The problem of material selection for automotive stamping parts
Auto stamping parts are metal stamping parts that constitute auto parts. There are many varieties, such as spring trays, spring seats, spring brackets, end caps, caps, compression valve covers, compression valve sleeves, oil seal seats, bottom covers, dustproof Covers, impellers, oil cylinders, lugs, brackets, etc. are all automotive stamping parts. When selecting materials for automobile stamping parts, first select metal materials with different mechanical properties according to the type and use characteristics of automobile stamping, so as to achieve the purpose of not only ensuring product quality, but also saving materials.
1. The selection of materials should be reasonable
Reasonable selection of materials is an important and complex task. The steel used for cold stamping is mainly steel plates and strips, which account for 70% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automotive stamping parts is very close. Damage not only determines the performance of the product, but also directly affects the process design of the automotive stamping process, and affects the quality, cost, service life and production organization of the product.
2. Three principles of selection
- (1) The selected materials should first meet the performance requirements of auto parts;
- (2) The selected materials must have better process performance;
- (3) The selected materials must be economical.
