Technical requirements and indexes of metal stamping parts

The technical requirements of metal stamping parts should be developed in the direction of complex structure, increased block size, more parts with related edges, greater bearing capacity and strict internal stress limit, which can promote the development of special stamping technology, such as hydroforming, precision forming, explosive forming, spinning, dieless forming, laser forming and electromagnetic forming;

Design index of metal stamping parts

1. To meet the product use and technical performance, and can be easy to assemble and repair;

2. It is beneficial to improve the utilization rate of metal materials of metal stamping parts, reduce the varieties and specifications of materials, and reduce the consumption of materials as far as possible. If allowed, low-cost materials can be used to make the parts as free as possible and less scrap blanking;

3. Under the condition of ensuring normal use, the requirements of dimensional accuracy grade and surface roughness grade should be lower as far as possible, which is conducive to the exchange of products, reduce waste products and ensure the stability of product quality;

4. The design of metal stamping parts should be conducive to the use of existing equipment, technological equipment and technological process to process them as far as possible, and to extend the service life of the die;
