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 cover parts such as body outer panels, and some load-bearing and support 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.
Stamping parts, if the process of hot stamping is used, 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 has the advantages of high molding accuracy, high molding performance, etc., 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.
When selecting materials, first, according to the type of automobile stamping and the characteristics of use, metal materials with different mechanical properties are selected to achieve the purpose of not only ensuring product quality, but also saving materials.
Usually, 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 should have good process performance;
- c The selected material should have good economy.
