Excessive temperature of engine piston can easily lead to overheating and melting and cylinder holding; overheating of rubber seals, triangular belts, tires, etc., can easily lead to premature aging, performance degradation and shorten service life; overheating of coils of electrical equipment such as starters, generators, regulators, etc., can easily cause burnout and scrap.

Automobile sheet metal is a technical means of automobile repair. In this respect, automobile sheet metal is equal to automobile sheet metal repair. It means that automobile body should be repaired after collision, that is, all the work except anti-corrosion and decoration spraying. For example, automobile body damage analysis, automobile body measurement, automobile body sheet metal shaping, stretch correction, stress relief welding, automobile body accessories assembly, adjustment and so on.

There are many sheet metal materials suitable for stamping, which are widely used in electronic and electrical industries, including: 1. SPCC of common cold rolled sheet SPCC refers to the continuous rolling of steel ingots by cold rolling mills into required thickness coils or sheets of steel. SPCC surface does not have any protection, and it is easy to be oxidized when exposed to air. Especially in humid environment, the oxidation speed is accelerated and dark red rust appears. The surface should be sprayed, plated or other protection when used.

As a member of the auto parts market, the sheet metal parts can not be left alone. There are many "secrets" that are not known to consumers. The sheet metal parts of automobiles, generally refers to the metal shell of automobiles, which is usually made of steel plates. On the basis of ensuring a certain strength, it is the basic requirement to minimize the weight. In addition to its protective and aesthetic functions, automotive sheet metal parts are also the main carriers of gas resistance for automobiles. Therefore, the quality and life of automobile sheet metal parts not only affect the appearance of the car, but also increase the resistance of air to the car due to the quality and deformation, which makes the economy decline.

According to Master Junjinluo, in order to distinguish the quality of sheet metal parts, we can start with packaging, weight, welding process, painting process and the degree of coincidence when loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after handing in the car. It is better to distinguish them from the packaging of the products in advance. Generally, the products produced by small factories will not print the contact mode and the factory address. Besides the contact mode and the factory address, the regular manufacturers will also have steel stamps, qualifications and inspection labels on the products. And so on, even if consumers have problems in the future use process, they can also have a way to safeguard their rights.

Stamping part is the production technology of product parts with a certain shape, size and performance, by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force and deformation in the die. Sheet metal, die and equipment are the three elements of stamping. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet metal stamping, short for stamping. Rongzhi automotive stamping parts indicate that it is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.

When choosing automobile stamping parts, it is often difficult for our friends, so we should choose automobile stamping parts according to those evidences? The following is Rongzhi automobile stamping parts collation of some information, through a variety of comparisons, I hope to be able to give some guidance to friends who want to buy Automobile Stamping parts! The details are as follows, for reference only.

The forming technology of automotive stamping parts has gained unprecedented recognition and reform with the development of demand, and has made tremendous progress in both depth and breadth. Especially in the aspect of combination with high-tech, the method and system have new changes.

The inspection method of automobile stamping parts is an important method to ensure the quality of finished products and high qualified rate. For the operators of stamping parts production enterprises, they generally need to know how to carry out the inspection. The following six inspection methods are mainly arranged for Rongzhi automobile stamping parts. Careful analysis can be divided into three categories: sensory inspection, polishing inspection, and so on. Tool inspection.

The following six inspection methods are mainly arranged for Rongzhi automobile stamping parts. Careful analysis can be divided into three categories: sensory inspection, polishing inspection, and so on. Tool inspection. Sensory inspection can be divided into visual inspection and touch inspection, polishing inspection can be divided into asphalt polishing and flexible screen polishing, and tool inspection can be divided into oil coating inspection and gauge inspection.

In the production process of automobile sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-function stamping die, only "high-speed" and "multi-function" can not meet the production requirements, only to achieve continuous conveying of sheet metal to stamping machine and stamping die, and stamped sheet metal workpiece can be removed from the stamping die and conveyed to the next stamping worker in a very short time. Only in this way can the economic benefits of the theory be guaranteed. Therefore, the correct stamping process should be: careful analysis and research of the whole stamping process of sheet metal parts, to ensure that the whole process from the beginning of sheet metal loading to the completion of sheet metal processing, has the expected shortest production beat, so as to achieve the best efficiency.

"In the next ten years, China's demand for automobiles will remain at an average annual growth rate of 13%-15%. Compared with the world's automotive powers, China's automotive market has a relatively long period of rapid growth. This period is probably from 2009 to 2023, spanning about 15 years. This is a period for all domestic spare parts enterprises. Good opportunities for development."

The annual National Two Sessions have already begun. The 2011 two sessions are just summarizing the key points of the 11th Five-Year Plan and looking forward to the 12th Five-Year Plan. Therefore, during the two sessions in 2011, there will be a lot of topics about how to make the automobile industry bigger and stronger, and how to change from quantity to quality.

The pyramid-shaped matching relationship between the whole vehicle factory and the automobile parts enterprises forms a relatively fixed interdependence relationship between the whole vehicle and the automobile parts enterprises, and the cooperative relationship between them is relatively strong. It is difficult for new entrants to replace the original suppliers.

As the name implies, automotive stamping parts are metal stamping parts that constitute automotive parts. In automotive stamping parts, one part becomes automotive parts directly after stamping, and the other part can only become automotive parts after stamping through welding, mechanical processing, or painting process. There are many kinds of automobile stamping parts, such as spring tray, spring seat, spring bracket, end cover, cap, compression valve cover, compression valve cover, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, supporting ear, bracket and so on, all belong to automobile stamping parts.

When choosing materials, the metal materials with different mechanical properties are selected according to the stamping type and use characteristics of automobiles, so as to ensure product quality and save materials.

For automobile stamping parts, because they are website products and keywords, so the learning requirements are comprehensive and specific. Therefore, its knowledge content and related difficult problems should be involved, and none of them can be omitted. So, based on this, the following will proceed immediately to improve everyone's learning efficiency.
