CNC machining center is widely used in the current machining market, and the future development trend is very good. It can be said that most parts are related to CNC machining. Especially in the auto parts industry, the vast majority of products are processed by CNC. For example, bumper, instrument panel, door plate rotating shaft, transmission shaft, gear, gearbox, wheel hub, brake drum, etc., first process small parts through CNC, and then bond them.

If it is found after investigation that the surface of the round corner of the die is rough, which causes the scratch on the surface of the stamping part, the round corner radius of the die should be polished. In addition, if there is dirt on the working surface or material surface of the stamping die during the stamping process, which causes the workpiece to be injured, it is necessary to keep the surface of the convex and concave die clean, and clean it before starting the work.

Many stamping factories often have high scrap rate when they are stamping. When the scrap rate is high, it not only causes the increase of production cost but also does not conform to the concept of energy conservation and environmental protection. Now the competition in stamping industry is so fierce, and the profit has been greatly compressed. If the scrap rate remains high, a batch of orders may not only have no profit but also lose money. So it is very important to solve the problem of high scrap rate of stamping parts. To solve this problem, the home page should know what causes the high scrap rate? Only in this way can we solve the problem. So what is the reason for the high scrap rate of automobile stamping parts?

Now there are many kinds of processing methods involved in the metal processing industry, and sheet metal processing is one of the more common processing methods. During the processing and production, the staff need to learn the processing technology first, so as to ensure the processing quality and accuracy of materials. This kind of processing method contains a lot of contents. People can complete the technological process of blanking and blanking when processing. After these processing procedures, the production purpose can be achieved. During the processing and production, workers need to pay attention to the parameter characteristics and technological methods, which are important aspects that can not be ignored.

What are the characteristics of automobile stamping parts processing The parts obtained by different production processes have their own characteristics, and each production method has its own advantages. Nowadays, people have a relatively large demand for the parts processed by stamping parts, because many people will choose the stamping method to get the products they need, so many people are not very good at the characteristics of stamping parts processing Understand, in the end, what are the benefits of parts produced by this process?

Car seat cushion material should also be considered. When selecting seat cushions, be sure to feel them carefully, touch them with your hands and smell them with your nose to see if there is any peculiar smell or hair falling. Attention should also be paid to the use, especially the owners of smoking, try not to smoke in the car, because this kind of wool fabric is easy to catch fire. The car seat cushion can be divided into three parts, five parts, eight parts and nine parts.

See if the joint is flat. In the process of handling and storage of spare parts, due to vibration and collision, burr, indentation, damage or crack often occur at the joint part, which affects the use of parts. Pay attention to inspection when purchasing.

The storage warehouse shall be kept within the range of relative humidity of no more than 75% and temperature of 20-30 ℃. For rubber products, especially for rubber mending, they should be stored in a special warehouse which can keep the ambient temperature no more than 25 ℃, so as to * * ensure safety.

With the increasing number of cars, it is more and more common to have one car for each person. However, there are always all kinds of losses in the use of auto parts, which need to be maintained. For many car owners, the maintenance of the car is nothing more than a simple cleaning of the car, as well as regular inspection to see if there are major problems. But in fact, car maintenance is far more than that. What's more, the frequent mistakes in car maintenance not only do not prolong the life of your car, but also accelerate the aging of your car. Why? This depends on whether the following kinds of maintenance errors occur during maintenance!

In the process of sheet metal processing, there are many processing technologies that need to be paid attention to, including welding, cutting and other processes, as well as bending, but no matter the bending radius or bending angle, we should pay attention to them to avoid failing to meet the design requirements.

First of all, we will see whether the data of automobile stamping parts can pass the customs. In some automobile manufacturing enterprises, in order to increase the weight, manufacturers will replace steel with plastic or light data as the original data of automobile parts. This may save fuel, but for those who are concerned about the weight of the vehicle, it does not meet the requirements.

Brake failure includes excessive brake pedal travel, slow brake action, low or even lost brake efficiency, and increased brake distance. There are three ways to eliminate the faults of auto parts:

The car is parked in the parking space of its own community. Although the ground lock is installed, it cannot prevent the theft of vehicle parts. This makes a lot of car owners feel helpless in spite of their anger. How to deal with the theft of auto parts in the community?

In the chassis, engine, transmission and other core parts, China automobile has long relied on foreign brands. After more than ten years of technology accumulation, the level of independent auto parts has been significantly improved, including the Great Wall, Chery, Chang'an and other mainstream automobile enterprises have independently developed core parts, and a number of models carried by them have also become popular.

Car stamping parts play an important role in car industry, so the raw materials are widely used in the production of stamping parts. Generally in the production of such stamping time, most of the use of cold stamping technology to produce or process. Because the use of cold stamping processing method in the production enterprises can meet the characteristics of a large variety of industrial products and a large number of products per unit time. Especially in the era of large-scale mechanized production, the processing method of cold stamping has been widely welcomed in large and small processing enterprises.

After the car sheet metal parts are taken for repair or repair, the next process is very important, that is, cleaning, do a good job of cleaning, and the car body is completely new. So how to clean it?

I believe that many car owners have encountered such problems. When they get up in the morning to drive, they find that the parts on the car are missing, which is a very helpless thing. Even if the vehicle has an anti-theft device, a ground lock is also installed, but it cannot prevent the loss of auto parts. Which auto parts are easy to be stolen?

The gradual formation and development of automobile sheet metal parts processing industry has greatly accelerated the development of manufacturing industry. The mode of sheet metal processing and distribution breaks the traditional method of simple purchase and transportation, introduces the concept of processing and distribution, which broadens the vision and accelerates the integration of traditional machinery manufacturing and technology.

Automobile sheet metal parts generally refer to the metal shell of automobile, which is usually made of steel plate. On the basis of ensuring certain strength, it is the basic requirement to reduce the weight as much as possible. In addition to the role of protection and beauty, automobile sheet metal parts are also the main carrier of automobile gas resistance. Therefore, the quality and service life of automobile sheet metal parts will not only affect the appearance of the automobile, but also increase the resistance of air to the automobile due to the quality and deformation, which will reduce its economy.

The manufacturer of rearview mirror folding device shall check whether the surface of parts is rusted. The surface of qualified spare parts has both a certain precision and a bright finish. The more important the spare parts are, the higher the precision, the more strict the anti rust and anti-corrosion of the packaging. Pay attention to inspection during purchase. If parts are found to have rust spots, mildew spots, or rubber parts are cracked or lose elasticity, or there is obvious turning tool pattern on the journal surface, they shall be replaced.
