Instruct and appraise the quality of auto repair and auto parts

 

Quality technical experts conduct evaluations, follow-up services, and accept complaints on the quality of auto repair and auto parts in accordance with national and industry standards. This is the best in the auto repair industry in Jiangsu Province. After China and the United States signed the “Accession to the World” agreement, Jiangsu Zhongda responded quickly to set up a quality appraisal center, issued a “Quality Commitment Letter” to users, and set up quality tracking points. They believe that China’s accession to the WTO is just around the corner, which is both an opportunity and a challenge for Chinese companies.

We must prepare early to be invincible in the future global market competition. Strive for Toyota to get permission to build cars in China, Xiali is about to be reborn. The National Development Planning Commission has approved two development projects recently. One is to invest 100 million yuan to establish Tianjin Toyota Motor Co., Ltd. as a joint venture with Toyota Motor Co., Ltd., and the production will be produced by Tianjin Motor Xiali Co., Ltd. The second is a medium-sized car in the global strategic small car series jointly developed by Japan Toyota Motor Corporation and adopts a common platform. The second is to invest 100 million yuan, based on the one and one in the world strategic small car series newly developed by Toyota Motor Corporation of Japan. , Implemented the Xiali car model replacement project.

At this year's fair, Zhongda's fully automatic computerized car washing machine became the new favorite of the old year. At the International High-tech Achievement Fair held in Shenzhen, the Zhongda gantry-type fully automatic computerized car washing machine attracted much attention. It has become a new favorite for its fast and convenient cleaning, clean and bright, powerful function, wide application range, fast investment recovery and other advantages.

Talking about the Software Upgrade Work of Auto Repair Service

 

In recent years, the expansion of corporate organizations, the addition of auto repair shops to service stations, and the lack of functions; the increase in interlocking sales departments, and the frequent interruption of external network dial-up communications, resulting in business data errors; network virus attacks, operations are threatened , Hardware and software upgrades should be urgently carried out.

The main content of the software upgrade is to increase the operation interface and application software modules of the database system and the corresponding database and index files, and modify the structure of the original database. The Web server, mail server, and database server of the intranet network are connected to the Internet metropolitan area network through the Gigabit switch and optical fiber through the two-layer Gigabit switch and the firewall; and are connected to the intranet through the three-layer Gigabit switch and optical fiber through the firewall. After several 100M switches of the company are transferred to each user; at the same time, the internal telephone network of the enterprise is connected to the three-layer Gigabit switch through the VDSL switch.

1. Due to the increase of organizational structure and the expansion of business scope, new functional modules of database application software should be added, and more than 50 databases and 20 temporary databases should be maintained. For some databases, fields and index files should be added to adapt to the new modules. For needs and query requirements, modules such as planning, accounts receivable, accounts payable, inventory analysis, inventory reporting, taxation, auto repair factory settlement, etc., are added to the original basis.

2. The original auto parts database system has the following problems: First, the key word for the database query is the auto parts spare part number. Due to the large number of manufacturers, there is a one-to-one relationship between the same auto part number and the part name, but the same name and part number are one-to-many. This requires operators to learn more than 10,000 spare part numbers before they can work. Today, labor mobility is a problem.

Which CNC Machining Manufacturer is Better for CNC machining? Find China Hardware and You Will Feel More at Ease

Keywords: Cnc Machining,CNC machining manufacturers,Which CNC machining manufacturer is better for cnc machining

Today, Mr. Yi shared a poor case, saying that when the company urgently needed parts, it found a CNC machining manufacturer, and the result was pitted. The reason is that there is no after-sales service after the CNC machining manufacturer's products are made, and it is still There are constant problems, which makes Mr. Yi very anxious, saying that there are so many CNC machining manufacturers now, which one is better? With such a question, let me explain it below.

Every choice may be right, but it may also be wrong, but the standard of my own measurement is different. Judging from the question of which CNC machining manufacturer is better, Yi always fails to find the right one, otherwise such a problem will not arise. Each CNC machining manufacturer has its own accounting standards, but the accounting methods are different. Some are calculated according to the customer’s drawings and needs, and some are calculated according to the customer’s general intention. In order to ensure the cost, some alternative materials will be used, so For the problem of Mr. Yi, if you can select and calculate the CNC machining process according to the drawings provided by the customer, then such a problem will not occur.

It can be seen that no matter what you choose, you must be cautious and not blind your eyes because of some petty gains. Which CNC center is good is not only the quality, but also the character. If the character is not good enough, no matter how good the product is, it is useless. To describe it in the words of an employee, it is to find a CNC center, find one that you can understand, rather than find a hidden one. For YIJINHardware, choose a good one, don’t choose an expensive one, choose a simple one, don’t choose a complicated one.

The benefits of micro-lubrication of engraving machine

During the milling and working process of the engraving machine, a large number of small debris will be generated. These debris can be seen everywhere in the work site. The traditional lubrication method will cause the debris to adhere to the surface of the workpiece, which will seriously affect the quality of engraving. At the same time, most traditional engraving machines are used A large number of emulsion spraying methods achieve lubrication and cooling. The disadvantage of this method is that processing any light cutting parts also requires a large amount of emulsion circulating spraying. On the one hand, it causes a waste of emulsion; on the other hand, it accelerates the aging of the equipment structure. After aging, the amount of emulsion leaking to the ground increases. When cutting tools rotate at high speeds, the emulsion will also be sprayed to the surrounding area. Over time, environmental pollution is serious. Workers’ skin and respiratory system are affected by the emulsion in such an environment, and their health is also affected. There will be potential injuries, which is also an important factor in the loss of operating technicians. The application of micro-lubrication technology has significantly improved the environment. After the product is processed, it saves a lot of cleaning work and reduces labor costs and energy consumption.

 

The engraving machine adopts the Doppel micro-lubrication system to achieve quasi-dry cutting. The system can perform lubrication and cooling of the processing tools and workpieces and remove debris according to the actual needs of the work during the milling process of the engraving machine. Any emulsion leakage, there is no excessive oil on the surface of the workpiece, thus reducing the subsequent cleaning work, saving manpower and material resources, quasi-dry cutting avoids the harm of workers’ skin damage, reduces the staff turnover rate, reduces training costs, and improves efficient. At the same time, there is no oil leakage, the equipment and ground environment are clean, and zero pollution is achieved.

Comprehensive requirements for the performance of internal combustion engine oil, gear oil, and hydraulic oil

 

As the automobile manufacturing industry continues to improve the transmission device, the ATF standard is required to rise accordingly, and the life span of the transmission system is the same. The main performance requirements of ATF oil are relatively high. The functional requirement is to improve the transmission efficiency of the power; it acts as a hydraulic oil, is a heat transfer medium, prevents wear, rust and corrosion, and lubricates the sliding and rolling surfaces. The characteristic requirements are excellent low temperature performance, oxidation resistance, foam resistance and air inclusion, compatibility with air-sealing cushions, compatibility with other ATF oils, and must be compatible with various friction materials.

ATF oil is a kind of oil with comprehensive performance and excellent quality, which concentrates the comprehensive requirements on the performance of internal combustion engine oil, gear oil and hydraulic oil. ATF oil is a lubricant with *complex formula, *difficulty in preparation, and high technical requirements. Especially today and in the future, the performance requirements of ATF oil are extremely demanding, and there are special requirements for base oils. Hydroisomerized ò, ó type base oils have excellent oxidation stability, and their low temperature performance is far superior to solvent refined oils. Another advantage of hydroisomerized dewaxing base oil is that it can reduce the impact on the friction performance of ATF oil.

ATF oil prepared with isomeric dewaxing base oil also has a certain energy saving effect. Therefore, the isomeric dewaxing base oil is the best component for the preparation of ATF oil, especially suitable for the production of ATF oil. Daqing Lubricant No. 2 Plant has the ability to produce ATF oil, and is currently sending the oil to the Southwest Research Institute for various tests of Dexronó, and will further obtain Allison C-4 certification.

Analysis of Energy Structure of Gas Locomotive

Adjust the energy structure to solve the problem of tight oil supply and high prices. At present, the price of liquefied gas and natural gas is much lower than that of gasoline, and when the “West-East Gas Pipeline” project is completed, cities along the route will have sufficient natural gas resources. Reduce the impact of cars on urban air pollution. Under the same technical conditions and working conditions, the emission of gas vehicles is much better than that of gasoline vehicles. Therefore, urban development and promotion of gas vehicles can reduce the pollution of the city's atmosphere by vehicles. The air purification project initiated by 13 ministries and commissions in April 1999? “Clean cars in action” activities accelerated the development of urban gas vehicles.

At present, the number of CNG and LPG gas vehicles in all parts of the country has been rising sharply, and this boom is still heating up. However, in the process of promoting gas vehicles in various places in the past two years, various problems have appeared. Not only did they fail to achieve the desired energy saving and pollution reduction goals, but also caused new energy waste and air pollution. In view of the problems that have emerged in the past two years, this article discusses several issues that should be paid attention to in the development of gas vehicles in cities. The technology of gas vehicles is not yet mature. Among the gas vehicles promoted in China in the past two years, a more serious problem is that each pilot city spends most of its power on the transformation of vehicles (accounting for nearly 80%), while ignoring the development and development of gas vehicles. Production (only 20%). Although the modified car is simple and easy to use, it can be used immediately, but the disadvantages far outweigh the advantages. Whether it is economical, environmentally friendly, or the performance of the vehicle itself, the situation is not optimistic.

Analysis of the current auto parts market

The fluctuation of auto parts this time is the second fluctuation since the fluctuation in the early 1980s. However, the market fluctuations in this continent are temporary, and the auto parts market will enter a stable development track. An analysis of the current auto parts market. Production status: According to statistics in 1985, the country has more than 2,400 auto parts manufacturing enterprises with 674,000 employees, accounting for 48 of the entire auto industry; the total production capacity is 8.4 billion yuan, accounting for 35.7 of the auto industry. Fixed assets (original value) 4.88 billion yuan, accounting for 35 of the entire automotive industry, total profits of 1.53 billion yuan, accounting for 32.3.

The main problems in production are: unreasonable production structure, blind development, and scattered power. For example, there are more than 20 manufacturers of automotive electrical appliances, more than 30 manufacturers of carburetor, and more than 100 manufacturers of automotive gears. The technical equipment and specialization level are low, the products are outdated, the quality is poor, the batch is small, and the development capacity is low. Poor, research, design, and testing methods are weak, and various professional and technical personnel are very lacking. In the management system, the management system is divided and self-contained, which prevents the parts industry from forming high-level, specialized, large-scale, and serialized production. pattern. 2. The production capacity is far greater than the need. The total production capacity of auto parts nationwide was 8.4 billion yuan. In 1986, 5.8 billion yuan was spent on supporting, repairing, and loading vehicles, which was nearly half of last year’s total demand. According to our statistics of 74 types of 440 factories and 74 types of auto parts listed in the mandatory plan for auto parts, the resources that could provide repair parts in 1957 were far greater than the needs of the national auto parts companies.

For automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.

Why are Bolts Tightened? What are the Benefits of Tightening Them?

Keywords:bolts,Why are bolts tightened? What are the benefits of tightening it?

Recently, there has been a lot of publicity about the spirit of craftsman, with reports on how rigorous the method of tightening bolts by German technicians is compared with the method of Tightening bolts by Chinese workers. Strictly speaking, in the process of equipment assemblly, the method of tightening bolts has been defined in the design, even with what tools?Screw bolt so simple thing, how to still decide an operation specification? Are designers really looking for trouble? In fact, the screw bolt is not as simple as imagined. The screw bolt is to make the bolt obtain an initial pretightening force. What role does this pretightening play?

 

Why to make the bolt to obtain an initial preload, this should start from the role of the bolt connection.

 

Transfer lateral force or torque

The bolt pretightening force generates pressure between the contact surfaces of the connected parts. The greater the pressure between the contact surfaces, the greater the transverse force can be transmitted. When the pressure on the contact surface is large enough, the transverse force is transferred entirely by the friction force, and the bolt only bears the pre-tightening force, not the shear stress and compressive stress, and the safety of the bolt is greatly increased, as shown in Figure 1.

 

Sealing function

When the bolt connection is used for pressure pipe or pressure vessel, the bolt should have enough pretightening force to play a sealing role, and the total pretightening force of the bolt should not be less than the pressure of the fluid between the contact surface, as shown in Figure 2. 

Prevent the structure from opening

Generally under fatigue load of bolt connection are not allowed to be fitting slotted, once produce gap between fittings, bolt tension will be increased with the increase of the tensile load increase quickly, the image below for the bolt tensile force and the load curve (as shown in figure 3), we can see that in the first half of the curve, by fitting between slit, bolt tensile slow growth, After the joint is slit, the bolt tension increases rapidly.

 

After the joint is opened, the amplitude of the alternating fatigue load of the bolt will increase rapidly, and the fatigue strength of the bolt will be greatly shortened.

Bolt tightening is analyzed from three aspects, including:

  • Bolt pretightening can prevent the opening separation of the connecting piece, improve the fatigue strength of the bolt connection;
  • To prevent the sliding of the connecting piece, relying on friction to achieve the role of the connecting piece to resist external load, to avoid the bolt subjected to shear load;
  • Prevent internal pressure leakage of pressure vessels.

 

The above three points are exactly the three parts of VDI2230 standard to calculate the bolt required preload, that is, the minimum preload required by the bolt, so as to design the appropriate bolt specification and performance grade, and finally determine the bolt preload.

Analysis on Innovation Experience of Mechanical Processing Equipment Management

Production equipment is an important tool and means for an enterprise’s production and operation, and it is also a material indicator of the level of social productivity development. The state of equipment technology not only affects the quality of the company’s products, but also affects the economic benefits of the company and the future of the company. Therefore, good management, good use of production equipment, and improvement of equipment management are of great significance to promote the progress and development of enterprises.

The daily management of equipment mainly includes the following: equipment inspection management; equipment lubrication management; equipment maintenance management; spare parts management and safety management.

1 Equipment inspection

Equipment inspection refers to the inspections performed by operators or maintenance workers on the equipment with visual inspection and simple test tools within a specified time according to the inspection items of the equipment maintenance account in order to maintain the specified performance of the equipment. Kind of inspection method. Spot inspection and daily maintenance have the following advantages: it can discover hidden dangers of equipment in time, eliminate faults in the bud, and prevent further deterioration of equipment parts and equipment accidents. Through the accumulation of inspection data, we constantly sum up experience, improve maintenance standards, maintain stable equipment performance, and extend equipment life. Participating in the daily inspection of the equipment can further grasp and understand the structure and performance of the equipment, and improve the sense of responsibility and the level of equipment maintenance for consciously taking care of the equipment. Spot inspection is one of the main channels for equipment operation information feedback. During the equipment inspection, the individual advocates full participation, and everyone related to the equipment management personnel, operators, and auxiliary personnel should put forward their own opinions, and then standardize and organize the inspection system with strong operability. The content of the inspection can be summarized as follows: There are ten major elements of equipment inspection, including pressure, temperature, leakage, lubrication, abnormal noise, heat, vibration, wear, and slack. They can be used as the basis for inspection and diagnosis. The key parts of equipment inspection include sliding parts, rotating parts, transmission connecting parts, supporting parts, hydraulic transmission parts, and parts corroded by media.

2 Equipment lubrication management

The correct selection of various lubricating materials and lubrication according to the specified lubrication time, location and quantity to reduce friction and wear, so that the equipment has good lubrication is an important guarantee for equipment safety, stable accuracy and efficient operation. Equipment lubrication management work requirements: draw up various management systems, prepare lubrication benchmarks, check the implementation of the lubrication system, and achieve “five determinations” (fixed point, fixed oil, fixed amount, fixed time, fixed person). Instruct the correct use of lubricating oil (grease), the reasonable storage of oil products and the daily maintenance of oil quality. If the equipment is found to be poorly lubricated and cause serious wear, the equipment should be stopped and measures should be taken to improve the lubrication condition in time. We will conscientiously manage the recovery and management of waste oil. Grasp the focus of lubrication work, that is, keep clean, use oil rationally, quantify on time, use proper methods, and prevent leakage and blockage.

3 Equipment maintenance management

Equipment maintenance management can be divided into five methods: after the event (passive) maintenance; preventive (active) maintenance; condition maintenance; improvement maintenance and transformation maintenance five methods, the five methods will be introduced separately below.

3.1 After the event (passive) maintenance

Post-maintenance is also called passive maintenance, which mainly refers to a maintenance activity that repairs the equipment after it is found to have problems. The advantage of this maintenance method is that it does not require advance planning, is simple and easy to implement, and can make full use of the equipment's spare parts.

The physical life of the components and maintenance costs are low. Scope of application: For equipment that is not important in production or can be substituted, post-event (passive) maintenance can be used.

3.2 Preventive (proactive) maintenance

Preventive maintenance is also called active maintenance. This maintenance method is to prevent equipment performance degradation or reduce the probability of equipment failure, maintenance activities carried out according to a predetermined plan. The advantage of proactive maintenance is that the maintenance is usually determined according to the operating time of the equipment

Time period. Scope of application: Preventive maintenance should be adopted for equipment that plays an important role in production or whose failure risk is greater than the maintenance risk.

3.3 Condition maintenance

Condition maintenance is a maintenance activity carried out based on the results of equipment condition monitoring. Its essence is the upgrade of preventive (proactive) maintenance. It is a targeted and quantitative maintenance activity. The advantage of conditional maintenance is that it overcomes the non-quantitative factors of preventive maintenance determined by equipment running time, which is beneficial to reduce maintenance costs and reduce preparation work. The scope of application of condition maintenance is: equipment should be equipped with relatively complete detection devices. Condition maintenance is the direction advocated and developed by equipment maintenance management.

3.4 Improve maintenance

The so-called improved maintenance refers to the improved maintenance method of equipment maintenance operations with new technology and new methods. The benefits of improved maintenance: Improved maintenance can greatly promote the improvement of the maintenance level and the quality of equipment maintenance.

3.5 Modification and maintenance

The maintenance activities that modify the structure of the equipment are called retrofit maintenance. The benefits of modification and maintenance: improve the performance of the equipment or enhance the reliability of the equipment. However, we should be cautious about this kind of construction. There should be argumentation and approval beforehand, and evaluation afterwards.

4 Spare parts management

At present, many companies implement the A, B, and C management methods of maintenance spare parts in the management of mechanical equipment spare parts. This method is helpful to ensure the needs of equipment maintenance and improve the reliability, maintainability and economy of the equipment. Spare parts that have a long cycle (slow turnover speed), high importance, fewer spare parts, difficult procurement and manufacturing, and higher prices are Class A spare parts. Class A spare parts should be controlled with emphasis, and should be ordered and purchased or processed in accordance with the most economical and reasonable use demand and time under the premise of ensuring supply to ensure normal production requirements. The control of B-type spare parts is not as strict as that of A-type spare parts, and the control of order batch, time and inventory can also be slightly looser than that of A-type spare parts. The consumption of C-type materials is not too large and there are many varieties. It is often possible to order one time according to the planned demand, or to extend the order interval appropriately to reduce the number of orders. There are a large number of spare parts in the spare parts warehouse. In the implementation of the A, B, and C classification management method, timely feedback of information has become a vital part. The management personnel of the spare parts warehouse should pay attention to the feedback of two aspects of information to the relevant departments: the information feedback of the minimum reserve and the information feedback of the spare parts warehousing.

5 Security Management

Safety management includes the management of personal safety and equipment safety. The production must be people-oriented. The safety of equipment management is also a guarantee of personal safety to a certain extent, and many of the above managements are aimed at equipment safety, so safety management will not be elaborated.

Key points of air filter cleaning

Although the traffic roads in various places are getting better and better, the dissatisfaction of the drivers with the roads still exists, especially in the places where they often pass. Road construction is a headache. Not only is the advancement blocked, The impact of construction dust on the car can not be ignored. At this time, car maintenance is necessary.

1. Regular cleaning of the air filter is the key

Because the air filter finely filters the air entering the engine cylinder, whether it can be kept clean and unobstructed is related to the life of the engine.

It is understood that the air filter is prone to blockage when walking on a smoke-filled road. If a dirty air filter is used during driving, it will cause insufficient intake of the engine and incomplete fuel combustion, which will cause the engine to fail to work. Stable, power drops, fuel consumption increases and other phenomena occur. Therefore, it is necessary to keep the air filter clean.

According to the master, according to the maintenance cycle of the vehicle, when the ambient air quality is generally good, it is sufficient to clean the air filter regularly every 5000 km maintenance cycle, but when the ambient air quality is poor, it is best to advance to every Once 3000 kilometers are cleaned up, car owners can choose to go to the 4S shop to clean up, or they can do it by themselves.

Hands-on method: The method of cleaning the air filter is actually very simple. Just open the engine compartment cover, lift the air filter box cover forward, take out the air filter element, and gently tap the end face of the filter element. If it is a dry filter element, it is recommended to use compression Blow the air from the inside to the outside to remove the dust on the filter element; if it is a wet filter element, it is recommended to wipe it clean with a rag. Remember not to wash with gasoline or water. If the air filter has been severely clogged, you need to replace it with a new one.

2. Internal and external recycling is a skill

During the driving process, if car owners cannot correctly grasp the use of internal and external circulation, the muddy air will cause great harm to the body. Using the external circulation, you can breathe the fresh air outside the car, driving at high speed, the air in the car will feel muddy after a long time, people are uncomfortable, and you cannot open the windows, you should use the external circulation to send some fresh air in; but if the air conditioner is turned on, it is In order to reduce the temperature in the car, do not open the outer loop at this time. Some people always complain that the air conditioner is not effective in summer. In fact, many people accidentally set the car into an external circulation state.

In addition, since most car owners are driving in urban areas, we remind car owners that in traffic jams during peak hours, especially in tunnels, internal circulation should be used as much as possible. When the car starts to drive at a normal uniform speed, it should be turned on to the outer loop state. When encountering a dusty road, when closing the windows, don’t forget to close the outer circulation to block the external airflow.

3. Air conditioning in the car is indispensable in winter

As the weather gets colder, some car owners close the windows without turning on the air conditioner. The owner, Miss Lin, is a living example. She said: Open the inner loop.” Does this approach work?

Master Yang told reporters that it is wrong to drive like Ms. Lin. Because the air in the car is limited, if you drive for a long time, it will cause the air in the car to become turbid and bring certain hidden dangers to driving safety. Master Yang recommends that car owners turn on the air conditioner after closing the windows. If you are afraid of the cold, you can switch on the air-conditioning fan to blow the air, so that the air in the car can be exchanged with the outside air. At this time, for dusty roads, it is very important to maintain the cleanliness of the air conditioner filter. It can filter the air that enters the cabin from the outside and improve the cleanliness of the air.

The replacement time and cycle of the air-conditioning filter is generally when the vehicle travels 8000 kilometers to 10000 kilometers, and usually only needs to be cleaned regularly.

Hands-on method: The car air conditioner filter is usually located in the toolbox in front of the co-pilot. Just take out the filter sheet and find a position that does not interfere with the wind to slap the dust out, but remember not to wash it with water. However, the reporter still recommends that car owners go to the 4S shop to find technicians to help clean up. In addition to the more secure disassembly and assembly technology, you can also borrow an air gun in the car wash room to completely blow off the dust on the filter.

Auto parts are classified according to the type of vehicle type

 

Auto parts are generally categorized according to the types of vehicle types. Newly added vehicle types require space, shelves and storage personnel. These problems are difficult for enterprises to solve in a short time. How to do a good job in the supply of auto parts for enterprises Auto parts supply is actually a science of material management, which is a science of cost balancing between insufficient and surplus auto parts materials. If we want to master this subject well, we must take the market economy theory as the guide, continue to explore in practice, and find a new way to do a good job in auto parts.

Improve the professional quality of management staff. The current auto parts supply work has greatly improved the quality requirements of the business personnel. First of all, the business personnel must be familiar with the composition of the whole vehicle and know the thousands of parts and accessories of each model. Secondly, it is necessary to understand the consumption law of auto parts, which are regular consumption, which are seasonal consumption, and which are rare and not easy to wear. Third, understand the production situation of various spare parts, which manufacturers produce the same products, and which factories are famous and high-quality products. Fourth, it is necessary to grasp the general interchangeability of accessories between various models, which can be used, which can be replaced, and which cannot be interchanged. A proficient business level is a prerequisite for doing a good job in auto parts supply.

According to the consumption of auto parts, determine the correct inventory structure. According to the past statistics, combined with the current reality, reasonable allocation of regular reserves, reduce the blindness of purchase orders, and reduce unnecessary inventory.

What kind of communication equipment five-axis machining is more worth choosing

Various engineering constructions require very high standards for various parts and components, so the selection of parts machining manufacturers is also very careful. If you want to choose machining parts suitable for your own work, you must have a special understanding of the cooperative machining manufacturers. Specifically, what kind of communication equipment five-axis machining is more worthy of the public’s choice?

A wide variety of parts that can be processed

Before deciding to cooperate with parts machining manufacturers, it is necessary to determine the types of parts that can be processed by the manufacturers. Manufacturers with more and more types of machining parts will have a broader application market to avoid the loss of cooperation between the two parties due to the incompatibility of the types of parts required by customers. Popular manufacturers can provide a variety of parts machining according to customer application needs, while ensuring the efficiency of parts machining, but also ensuring that the products are more in line with the specifications.

The quality of processed parts is better

Reliable communication equipment five-axis machining manufacturers provide better processed products, which not only meet the needs of work and application, but also meet the rigid standards of parts production. In addition, they have high wear resistance in practical applications and can be used for a long time. To avoid frequent damage, customers also need to replace parts frequently, which not only brings economic losses to customers, but also affects work progress.

Higher machining efficiency for various parts

If you want to know which one of the five-axis communication equipment is reliable, it depends on the actual machining and production efficiency. It can produce parts and components that meet the requirements in a shorter time. Not only can the parts and products be put into use as soon as possible without delaying the actual work progress, And in contrast, it can create more profitable income in a short period of time, avoiding too low machining and production efficiency to meet the customer’s demand for quantity.

Customers choose cost-effective communication equipment five-axis machining manufacturers to establish cooperation in a targeted manner. In addition to the above points, they also need to look at the durability of the actual processed parts and products, so as to avoid some factories from greatly reducing the quality of parts in order to improve machining efficiency. While burdening customers, it also delays work progress to a certain extent.

Summer car maintenance tips

In the hot summer, the car is running at a higher load, and the mechanical wear and aging fatigue will be worse than usual. Daily maintenance can make your car’s normal service life longer. Therefore, how to carry out summer maintenance work on the car in advance is very critical. Here are a few common summer maintenance tips for everyone.

1, engine maintenance

In summer, we should try to choose some higher viscosity oil, because the viscosity of the oil will change with the increase of temperature. When the temperature is higher, the viscosity of the oil will decrease, the oxidation resistance will be poor, and it will be easily deteriorated. The oil film formed inside the engine is thin and uneven, which is likely to cause failure. In addition, under the condition of ensuring sufficient lubrication, lubricating oil with corresponding viscosity should be selected according to the temperature range, engine temperature and actual vehicle conditions during use.

2, high temperature explosion-proof tire

Because the higher the temperature, the higher the air pressure inside the tire. In the hot summer weather, excessively high or low tire pressure can easily cause abnormal heat and instantaneous inflation of the tire. Therefore, in summer, pay special attention to frequently checking the tire pressure to keep it within the normal range. In addition, the tires are prone to overheating during long-term driving or high-speed driving in summer, and the air pressure increases at the same time. At this time, you should stop to dissipate heat, and it is strictly forbidden to bleed to reduce pressure or splash water to cool down. At the same time, due to the increase of rain in summer, to eliminate the impact of slippery roads on driving safety, it is necessary to check the tire pattern, including the tire pattern type and pattern depth. Generally speaking, manufacturers will set wear marks on tires. When the pattern is worn to the point that this mark is exposed, it means that we need to replace the tires.

Precautions for car maintenance after rain

Summer is here, heavy rain and light rain continue to cool down the cities everywhere, people are more comfortable, and the cute car has experienced wind and rain. The rain has stopped, it’s time to do maintenance for your car, or symptoms such as mildew in the car and unlit car lights may come to your troubles.

**Step: Dehumidification inside the car

In fact, the work of dehumidification should be done when it rains. When it rains, the cold wind should be turned on. This can not only remove the fog, but also dehumidify. Pay more attention when the rain stops. The accumulated moisture must be removed as soon as possible, otherwise conditions such as mildew will easily occur. In addition to turning on the air conditioner to dehumidify the car, it is best to buy a simple dehumidification box, so that the parts in the car will not be susceptible to moisture after overnight. In addition, putting a roll of toilet paper in the car also has the effect of dehumidification.

In addition to the welding of the door and the welding part of the car body, it is easy to rust and corrode after the rain. The hinges, locks and other iron parts inside the door are also easy to get damp because they are covered by the door trim. Therefore, the owner can find a shade when it is sunny. Wherever possible, open all the doors and trunk covers to allow the moisture in the car to drain and ventilate, and then remove the foot pads and seat covers in the car, rinse and dry.

Step 2: Sterilize inside the car

After the rain in summer, due to temperature and other factors, it is easier to breed various germs, so it is particularly important to disinfect and sterilize the interior of the car. The key areas to be cleaned should be seats, air-conditioning outlets, central control panels and dead corners. You can use a professional car interior cleaner and wipe it with a dry cloth.

When cleaning the center console, prevent the cleaning agent from penetrating into the CD, speakers, radio and other electrical equipment to corrode electrical components.

The third step: maintain the chassis

The summer temperature is high, coupled with rain, the chassis is vulnerable to damage. Exhaust gas, dust, noise, and moisture will penetrate into the body through the small holes in the chassis, causing the body to rust and peel off. Therefore, the chassis must be maintained after heavy rain.

In addition to simple cleaning, “chassis encapsulation” is also a good choice. It can isolate the chassis from the outside world, achieve the functions of anti-corrosion, anti-rust, and sound insulation, and extend the life of the body. Before “chassis encapsulation”, use a special detergent to remove the asphalt and oil stains attached to the chassis, and dry it. Any stains will affect the firmness of the encapsulation. Before encapsulation, the heat dissipation part of the transmission system and exhaust system should be shielded to avoid affecting the normal operation of these parts after encapsulation.

Step 4: Clean the exterior

The car is like its own, don't bother to wash the car after the rain, otherwise it will seriously affect your personal image. In fact, it is not only a personal image problem. In addition to sewage and silt in rainy days, the acidic substances contained in rainwater will seriously damage the car body and paint surface. If it is not treated in time, the car body will lose its luster and affect the appearance.

To prevent acid rain from damaging the car body, the simplest and most effective way is to wax, but if you want to achieve a very long-lasting protection effect, you must seal the glaze. Both can prevent the paint from fading and aging, thereby protecting the paint from aging. harm.

Step 5: Check the circuit

After the rain, the car may have an impact on the performance of some parts of the car due to multiple water injections, and in severe cases, the car cannot be turned on normally. When the circuit is exposed to water, it is likely to cause a short circuit. If the engine stalls while traveling, it cannot be ignited again, otherwise it is very easy to cause the engine to be scrapped. If there is water, the circuit equipment should be processed in time after passing. You can use non-fiber paper towels and textiles to dry the circuits one by one before starting.

In addition, checking the brake system is also very important. Because the brake system has a very strong adsorption force, rainwater is very easy to enter the brake fluid, which will affect the braking effect, and may cause brake failure in serious cases. It is recommended to go to a professional repair shop for inspection after rain to prevent future troubles.

Step 6: Check the headlights

Rainy weather can easily cause water in the headlights. The brightness of the headlights will be affected after the water enters. A lot of water may damage the headlights and change the direction of the headlights, which brings hidden dangers to driving safety. Therefore, it is important to check whether the headlights are flooded.

If you find that there is water fog in the headlights, you can turn on the headlights and turn on the high beams, and see if the water fog in the headlights starts to disappear after ten minutes, and whether it can completely disappear after one hour. If it disappears, don’t worry. , But if there is still water mist, it is necessary to go to a professional after-sales service station for treatment.

Improve auto parts sales economy

The auto parts market is generally affected by the big market, and demand has been flat after the second half of last year. However, the auto parts market is growing in demand with the increase in car ownership, which is everyone’s consensus. The national auto parts industry target has been set, measures are gradually introduced, supporting policies are gradually implemented, and the auto parts distribution system is further deepening reforms, and the agency system is in the ascendant, which provides a good economic environment for the development of the auto parts market. According to low standards, the total national demand for repair parts is 50 billion yuan, the six provinces and one city in East China are 14 billion yuan, the provinces and cities where the 10 provinces and cities are located are 19 billion yuan, and the user demand in Shanghai is 1.5 billion yuan. Based on the above analysis of the situation, the seminar believes that the first half of 1996 was a turning point for the start of the market, and the sales of automobiles and accessories in the first quarter became more difficult. We cannot sit back and watch the loosening of the macro economy, let alone miss the opportunities that appeared in the business activities at the beginning of the year. We should be full of confidence, muster the courage, face the reality, make the best use of the situation, grasp the business as soon as possible, and seize the fleeting signs of rebound in sales. , Put up the sales of cars and accessories.

In terms of vehicle sales, it is necessary to maintain and develop the original resource channels, consolidate and straighten out the integration of industry and trade, special dealership and agency business; and organize the resources of marketable vehicles and agricultural vehicles according to market demand, and make advances based on the needs of the market. , Strengthen research and after-sales technology, maintenance, and supply services. Adopt various preferential and flexible methods to expand sales, and at the same time open up the old car sales market, take the operation of old cars as a new economic growth point, and prevent assembled cars, eliminated cars, and inferior cars from entering the market. For high-quality products, implement unified distribution, share agency, increase batches, and increase grades, strive for the largest discounts from the factory, and strive for economies of scale. Be flexible and adaptable in terms of methods. Whether wholesale or retail, we must strive for market share with brand-name varieties, high quality, preferential prices, and high-quality services.

Accessories expand the business scope through wholesale

 

Timely feedback information to guide production and sales. This means that the main company can provide various market information for the manufacturer through its own business activities, which is convenient for the manufacturer to guide and organize production; at the same time, it can provide a variety of business guidance and business assistance to the retailer to make it more Reasonably organize purchases and expand sales. This warns us that in the information age, wholesalers have become more and more responsible for information feedback in the entire distribution activities. The above points show that the wholesale business of state-owned companies is an objective requirement in the development of business modernization and an important way for enterprise development.

Expanding the wholesale ratio is a powerful measure to increase market share and further consolidate the position of the main company. With the successive opening up of the production material market, automotive industrial products have become commodities and must be sold in the market, which also brings opportunities for the development of collective and individual economies. At present, collective and individual spare parts outlets have spread all over the country, and the national policy to rectify the spare parts market has not been put in place, and the current national policy does not stipulate that state-owned units must purchase auto parts from state-owned spare parts companies. Make parts distribution and maintenance companies in each collaboration area work together and implement joint management. In this way, the supply and demand sides of auto parts meet directly and establish a linkage relationship.

The sales agent system for automobiles and auto parts is an inevitable product of the development of commodity production. Expanding the proportion of wholesale is an important means to increase sales and increase economic efficiency. In auto parts management, since the state-owned company ** management dominates the world, the business structure was broken. In the spare parts market, a state-owned, collective, and individual three-pronged situation has formed. The market for main companies is relatively shrinking, and some companies have suffered losses, and it is difficult to maintain their lives.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.

Application examples of industrial robots in numerical control processing

This article describes the application of FANUC robots to motor housing production lines. By adopting automatic robot loading / unloading technology and iRVision vision system, the trajectory of the robot can be rationally planned, and the Machining technology of industrial robots and the Machining technology of numerical control can be organically combined. The workpieces are automatically loaded and unloaded, and the finished products are automatically stacked, enabling high-precision, high-efficiency, low-cost machining.

Keywords: industrial robot, Cnc Machining combination, industrial automation

1. FANUC Robot

The automatic Machining line is equipped with two FANUC robots, the M-20iA handling system robot. One of the robots is the walking robot R1. Controlled by FANUC servo motor αi F12 / 3000, it has precision reducer, gear, rack drive, high reproducibility and can be easily adapted to the mechanical layout on both sides of the rail.

It is mainly used for gripping rough workpieces, loading machine tools, and gripping workpieces during machining. In addition, the processed product is taken out and transported to the conveyor belt.

Another fixed robot, R2, uses FANUC’s unique intelligent robot technology (iRVision vision function) to punch and stack finished products into baskets. FANUC Robot M-20iA The joints of each part of the robot are joint points or coordinate systems. The shape and position of each joint is shown in Figure 1.

2. Layout of automatic production line equipment

The motor casing automatic Machining production line consists of a supply conveyor and a blanking conveyor belt (equipped with the iRVision vision system). Figure 2 shows the device layout of walking robot R1 (rail type), fixed robot R2, two VM850 vertical machining centers, one CLX360 CNC lathe, completed basket, and system control cabinet.

CNC machining process

The workpiece is a motor casing for mass production as shown in Figure 3. The material is ADC12 aluminum alloy. Machining includes face milling, tapping, and boring.

  • (2) As shown in Fig. 5, two VM850 machining centers, φ5.5 mm for drilling, aperture chamfering process.
  • (3) The CLX360 CNC lathe chamfers inner holes, stepped holes, and holes as shown in Fig. 6.

In addition, special jigs need to be designed. The fixture of the machining center adopts the internal clamp method, and the CNC lathe adopts the external clamp method. The combined application technology of robots and Cnc Machine tools processes workpieces by automatic loading and unloading to improve machining efficiency.

4. Robot automatic loading / loading operation design

Design pneumatically fixed parts for robots based on the shape characteristics of workpieces including pneumatics, sensors and mechanical parts.
The work Machining process is as follows.

  • 1. Place the blank work on the in-feed conveyor.
  • 2. The walking robot R1 compound jig grips the rough-machined workpiece, moves it to the position of the machining center 1, and places the workpiece on the dedicated jig of the machining center 1. As shown in Figure 7.
  • 3. After the machining center 1 is completed, the compound claw of the walking robot R1 removes the workpiece and moves to the position of the machining center 2, and mounts the workpiece on the dedicated jig of the machining center 2.

4. After the Machining center 2 is completed, the walking robot R1 takes in the work to the position of the CNC lathe and mounts the work on a dedicated jig.

After the workpiece is machined, the workpiece is removed and the robot walks to the workpiece turntable to perform the workpiece flip and swap positions.

5. After the workpieces have been replaced on the turntable, the robot R1 places the final product on the unloading conveyor.

The workpiece is unloaded by Robot R2 and automatically placed in the finished basket.

This completes the complete process. Each Machining step has a corresponding beat. After adjusting the CNC machining program and the robot motion program, you can perfectly combine CNC machining with robot loading and unloading.

Special jig design

According to the machining work of each of the three CNC machine tools, three sets of composite pneumatic clamps were designed and introduced as follows.

(1) Vertical machining center 1 Special jig:

The main shortcomings of the four-roll calendering method in the production of inner lining

At the same time, the airtight layer film to be used on the guiding device is guided and enters the centering compound platform through the film conveyor belt. On the centering compound platform, the airtight layer film and the transition layer film are combined to form an inner lining. . The composite inner lining layer enters the winding device through the film conveyor belt for winding, and the hard polyester film is put on the winding. Similarly, the winding temperature is lower than 40 ℃, and the inner lining film is rolled on an I-shaped reel. At this point, the inner liner is produced and enters the forming process for use. Main technical parameters The main technical parameters of the four-roll calendering method for the production of inner lining are as follows; calender power 4×40kW; single-layer film thickness 0.4~3.0mm; film width composite centering error ≤ 2mm; film winding uniformity error. Main advantages and disadvantages The advantages of the four-roll calendering method to produce the lining layer are mainly manifested in the following aspects: (1) faster production speed; (2) better surface quality of the produced film; (3) lower temperature of the rubber compound; ( 4) Lower equipment investment.

The four-roll calendering method mainly has the following shortcomings in the production of inner lining: (1) Since the rubber material fed into the roller gap of the calender is a reciprocating rubber strip, the rubber material has a certain amount of accumulation on the roller gap. The accumulated rubber is rolled into the nip for several times before being rolled, so it is easy to entrap air and make the rolled film contain air bubbles. (2) Because it is easy to form bubbles, the calendering method is only suitable for calendering to produce films that are not too thick. Generally, the thickness of the calendered film is not more than 3mm. For thick products (such as transition layer film), only the pasting method can be used. Production. (3) Since the roller of the four-roll calender is of no belt type and adopts the layered method, the cross-sectional shape of the inner lining produced by the calendering method can only approximately meet the structural design requirements. (4) The thickness error of the film is affected by the amount of accumulated glue. Therefore, the feeding should be carried out continuously and evenly to keep the amount of accumulated glue constant.

Combine auto parts marketing with maintenance industry

 

Combining the management of the auto parts distribution industry with the management of the auto repair industry. In the process of implementing the industry management of auto parts distribution, we not only manage according to the characteristics of the distribution industry, but also specially plan to use the advantages of the city's industry management to make the auto parts distribution industry. The management and the management of the automobile maintenance industry are organically combined, and the close relationship between the common nature is used to form an inseparable situation of mutual benefit. After implementing the management of the parts distribution industry, we will include all parts distribution companies in the city into the scope of the maintenance industry cooperation zone, so that the parts distribution and maintenance companies in each cooperation area will work together and implement joint management. In this way, the supply and demand sides of auto parts meet directly and establish a linkage relationship.

For many years, the auto parts market has been under the guidance of the planned economy as the mainstay and market regulation as the supplementary policy. At present, the number of collective and individual auto parts stores far exceeds that of state-owned stores. Looking at the situation in Heilongjiang Province alone, there are more than 400 auto parts stores in the province, but there are only more than 100 real state-owned enterprises. The coverage of state-owned stores is also quite limited, and the sales of state-owned stores are less than one-third of the province’s total sales. , The status and role of the main company has not been fully reflected. With the development of the economic situation, market competition will become more intense, and state-owned companies are facing severe challenges. So, what attitude should the main company take to meet the challenge, continuously enhance its competitiveness, and improve its economic status? We believe that to achieve this goal, state-owned companies should gradually develop towards wholesalers and agents.

How to improve the auto parts market in our city

 

At the same time, some business departments have become a place for thieves to sell dirty, making criminals even bolder and causing harm to public order. What makes people feel righteous is that this situation has become a strange phenomenon in the auto parts industry that the viewers are not surprised, the others are not afraid, and the recipients are worthy of it. It also severely threatened the status of state-owned channels.

At present, China is still in the initial stage of socialism. Privately owned vehicles are less than 10 of the total number of vehicles. The vast majority of vehicles are public vehicles. Whether it is buying auto parts or repairs, it is public money. The purchaser does not need to pay for it. Therefore, buying accessories is not like buying department stores and daily necessities for price and quality. It does not matter to the price and quality of auto parts. If private individuals can benefit from it, why not do it? And most car users Leaders are not familiar with auto parts, let alone product quality. There are not many vehicles in some units, and these vehicles are in an important position for accomplishing the tasks of the unit and as a tool for leadership. So as long as the vehicle is running, the requirements for other issues are not strict. This is also one of the reasons for the existence of strange phenomena.

At present, there are too many auto parts outlets in Chongqing, which greatly exceed social needs. We should no longer blindly develop social outlets. At the same time, we must clean up existing outlets, resolutely ban illegal operators, rectify unqualified ones, and strengthen industry management. , Implement macro control, rational layout, and strengthen the management of purchases, finances, and prices. The main channel should provide assistance, support and guidance to social outlets in business.

For automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.

How to properly protect the sealing performance of the car

 

In the hot summer weather, spontaneous combustion of vehicles caused by oil circuits and electrical circuits often occurs, which often causes the vehicles to be scrapped and sometimes even endangers personal safety. In this regard, fire protection professionals proposed that “cleaning in the cabin” can prevent spontaneous combustion, and specifically gave two key preventive measures.

A few days ago, in front of the business department of China Merchants Bank, Zhongshan Road, Heping District, Shenyang City, Liaoning Province, a black smoke suddenly appeared from the engine compartment of a silver-gray car, and then spontaneously ignited. After the firefighters rushed to the scene, they reminded the car owner to “don’t open the car cover yet”, and helped extinguish the fire, but the car was basically scrapped.

The reporter learned from the Shenyang Fire Brigade that since May, the temperature has risen significantly, and spontaneous combustion of vehicles has begun to increase. In just half a month, 36 car fire accidents have occurred in the city, which is the highest in the past year. At present, most common automobile spontaneous combustion incidents are caused by short circuits in high-temperature weather, and the probability of occurrence is more than 60%; the second is the oil circuit problem. A recent change is that spontaneous combustion incidents caused by car decoration have also begun to increase.

Sun Guofeng, a senior engineer of the Shenyang Fire Fighting Detachment, believes that there are two main causes of vehicle spontaneous combustion. One is the short circuit caused by the aging of the circuit. A large part of the spontaneous combustion accidents are caused by fire in the engine compartment. Connection, etc. caused by short circuit and fire. Another cause is the aging of the oil circuit leading to a fire. Because some oil leakage and oil leakage in the engine room have not been detected in time, the temperature in the engine room rises sharply in the summer high temperature environment, which is enough to ignite the leaking oil and cause the risk of spontaneous combustion. “‘Cabin cleaning’ can prevent spontaneous combustion. For short circuits caused by aging of the circuit, the way to avoid it is to develop a good inspection habit and regularly check some circuits in the car; and for the problem of aging oil circuits, wash the car at the same time. It is necessary to clean the dust and oil stains in the engine compartment, and if necessary, go to the repair shop for professional cleaning, so as to discover and eliminate the risks in time." He suggested.
