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 cylinder, lifting lug and bracket.
Cold stamping process is widely used in the production of automobile stamping parts, which is suitable for the needs of multi-variety and mass production of automobile stamping parts industry. 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 the 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 used in the whole vehicle. Cold stamping materials are closely related to 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. Therefore, the reasonable selection of materials is an important and complicated work. (Photo/Text/Photo: Pacific Auto Network Chen Jie 2)
