Automobile Press Parts , as the name suggests, are metal stampings that make up automotive parts. In automobile stamping parts, some parts are directly turned into auto parts after being stamped, and the other parts need to be welded, machined, or painted to be auto parts after being stamped. There are many types of automotive stamping parts, such as automotive shock absorber stamping parts, spring trays, spring seats, spring brackets, end covers, covers, compression valve covers, compression valve sleeves, oil seal seats, bottom covers, dust covers, impellers, oil Tubes, ears, brackets, etc. are all automotive stampings.
When selecting materials, first select metal materials with different mechanical properties according to the type of automotive stamping and use characteristics, in order to achieve the purpose of ensuring product quality and saving materials.
Generally, the following principles should be followed when selecting automotive stamping materials:
a The selected materials should first meet the performance requirements of automotive parts;
b The selected materials must have good process performance;
c. The selected materials should have better economy.
In the production of automotive stamping parts, a large number of cold stamping processes are used to meet the needs of multiple varieties and mass production of automotive stamping parts industry. In medium and heavy-duty vehicles, most of the cover parts, such as body panels, and some load-bearing and support parts, such as frame and carriage, are automotive stamping parts. The steel used for cold stamping is mainly steel plates and steel strips, which account for 72.6% of the vehicle's steel consumption. Cold stamping materials are closely related to the production of automotive stamping parts. The quality of the material not only determines the performance of the product, but also directly affects the product. The process design of automotive stamping parts affects the quality, cost, service life and production organization of the product, so the reasonable selection of materials is an important and complex task.
