Selection of automotive stamping parts
If the hot stamping forming process is used for automobile stamping parts, the benefits it can bring are mainly to realize the lightweight production of automobiles, and to effectively improve the strength of stamping parts.
If the hot stamping forming process is used for automobile stamping parts, 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 also has the advantages of good molding accuracy and good molding performance, 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.
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 body outer panels, and some load-bearing and supporting parts such as frame, carriage and other auto parts are auto stamping parts. The steel used for cold stamping is mainly steel plates and steel strips, which account for 72.6% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automobile stamping parts is very close. The quality of the materials not only determines the performance of the product, but also directly affects the production. The process design of the automobile stamping process affects the quality, cost, service life and production organization of the product, so the rational selection of materials is an important and complex task.
We produce all kinds of metal parts include machine parts, metal stamping, deep drawn, sheet fabrication, welding parts, and assemble products
