What are the benefits of hot stamping for automotive stamping parts?

Auto stamping parts, as the name suggests, are metal stamping parts that constitute auto parts. In automobile stamping parts, some of them become auto parts directly after stamping, and the other part needs to be processed by welding, machining, or painting before they can become auto parts after stamping. There are many kinds of automobile stamping parts, such as spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil seal, etc. Tubes, lugs, brackets, etc. are all automotive stamping parts.

Stamping parts, if the process of hot stamping is used, the benefits it can bring are mainly to realize the lightweight production of automobiles, and to effectively improve the strength of stamping parts. Moreover, it is molded at high temperature, so it has the advantages of high molding accuracy, high molding performance, etc., and there is no springback problem. The auto parts that can be used are the anti-collision beams, safety parts and car body structural parts.

If the 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, mainly include the following, which are:

Blanking: That is, the sheet is punched into the desired outer contour blank for subsequent fabrication.

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

Transfer: The heated material is taken out of the heating furnace and then sent to the thermoforming mold. The key point is that the speed should be fast. If the speed is too slow, it will affect the quality of the stamping parts.

Stamping, quenching and subsequent treatment: stamping and forming the material at a certain temperature so as not to affect the forming performance of the material. After the material is formed, the mold must be closed and kept under pressure for a certain period of time, so that the material has good properties, and at the same time, quenching treatment is also required. In the follow-up treatment, it is mainly some surface treatment, or small fabrication such as drilling.
