Auto stamping parts, as the name suggests, are metal stamping parts that make up auto parts. Among the automobile stamping parts, one part becomes auto parts directly after being stamped, and the other part needs to be processed by welding, machining, painting, etc. to become auto parts after being stamped. 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 Tubes, lugs, brackets, etc. are all automotive stamping parts.
When selecting materials, first select metal materials with different mechanical properties according to the type of automobile stamping and use characteristics, so as to achieve the purpose of not only ensuring product quality, but also saving materials.
Generally, the following principles should be followed when selecting materials for automotive stamping parts:
a The selected materials should first meet the performance requirements of auto parts;
b The selected material must have better process performance;
c The selected materials should be economical.
A large number of cold stamping processes are used in the production of automotive stamping parts to meet the needs of the automotive stamping industry for multi-variety and mass production. In medium and heavy-duty vehicles, most of the covering parts, such as the outer panel of the body, and some load-bearing and supporting parts such as the frame, the carriage and other auto parts are all automobile stamping parts. The steel used for cold stamping is mainly steel plates and strips, accounting for 72.6% of the steel consumption of the whole vehicle. Cold stamping materials are closely related to the production of automotive stamping parts. The quality of the materials not only determines the performance of the product, but also directly affects the performance of the product. The process design of automobile stamping technology affects the quality, cost, service life and production organization of the product, so the reasonable selection of materials is an important and complicated task.
