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.

If stamping parts are formed by hot stamping, what are the main processes?

Stamping parts, if they are formed by hot stamping, then, in the specific process, there are mainly the following, for:

Blanking: That is, stamping the sheet into the required outline blank for subsequent processing.

Austenitizing: It consists of two stages: heating and holding. The purpose of processing is to heat the material to a suitable temperature so that it has good plasticity.

Transfer: The heated material is removed from the heating furnace and then fed into the hot forming die. The key point is that the speed is fast, if the speed is too slow, it will affect the quality of stamping products.

Stamping, quenching and follow-up treatment: Stamping material, at a certain temperature, in order to avoid affecting the formability of the material. When the material is formed, the die should be closed and pressed for a certain period of time in order to make the material have good performance, and at the same time, quenching treatment should be carried out. In the follow-up treatment, mainly some surface treatment, or drilling and other small processing.

What are the benefits of hot stamping for stamping parts? And, which parts of the car can it be used in the production?

Stamping parts, if hot stamping forming technology is used, its benefits can be mainly to achieve lightweight production of automobiles, and effectively improve the strength of stamping parts. Moreover, it is formed at high temperature, so it also has the advantages of high forming accuracy, high forming performance, and there will be no springback problem. The automobile parts that can be used are anti-collision beam, safety parts and body structure parts.
