Precision automobile stamping parts

Precision automobile stamping parts, as the name implies, is the metal stamping parts of automobile parts. In automobile stamping parts, some parts become auto parts directly after stamping, and the other parts need to be processed by welding, machining, or painting. There are many kinds of automobile stamping parts, such as spring tray, spring seat, spring bracket, end cover, seal cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, support ear, bracket, etc.
Material selection principle of precision automobile stamping parts
In the selection of materials, the metal materials with different mechanical properties are firstly selected according to the type and use characteristics of automobile stamping, so as to ensure the product quality and save materials.
Generally, the following principles should be followed when selecting the materials of automobile stamping parts:
A. the selected materials should first meet the performance requirements of automobile parts;
B. the selected materials should have good technological properties;
C. the selected materials should be economical.
Reasonable material selection of precision automobile stamping parts
A large number of cold stamping processes are used in the production of automobile stamping parts, which is suitable for the needs of multi variety and mass production of automobile stamping parts. In medium and heavy-duty vehicles, most of the covering parts such as the body outer panel, and some load-bearing and supporting parts such as frame and carriage are automobile stamping parts. The steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the steel consumption of the whole vehicle. The cold stamping materials have a close relationship with the production of automobile stamping parts. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts, and affects the quality, cost, service life and production organization of products An important and complex task.
