How to choose steel plate and steel belt for automobile stamping parts
Steel plates and strips in automotive stampings: The steel used for cold stamping is mainly steel plates and steel strips, accounting for 72.6% of the steel consumption of the whole vehicle. Cold stamping materials are closely related to the production of automotive stampings, and the materials are good or bad. It not only determines the performance of the product, but also directly affects the process design of automotive stamping parts, and affects the quality, cost, service life and production organization of the product. Therefore, the rational selection of materials is an important and complex task.
High-strength steel: The rapid development of the automobile industry has played an important role in the development of the national economy and society. However, affected by problems such as energy shortages and environmental pollution, the contradictions in the development of the industry have become increasingly prominent. Looking to the future, the development of this industry can only be sustainable if it is based on the background of nature, ecology, energy conservation, and safety. Under this background of automobile stamping parts, the application of automobile lightweight and high-strength steel has become an important development direction. However, due to the increase in the strength of high-strength steel sheets, the traditional cold stamping process is prone to cracking during the forming process, which cannot meet the processing requirements of high-strength steel sheets.
