Metal stamping parts design principle is what?

1) Design of stamping parts must meet the product use and technical performance, and can be convenient for assembly and replacement. （ 2) Design of stamping parts must be beneficial to improve the utilization rate of metal materials, reduce material varieties and specifications, as far as possible to reduce the consumption of materials. In the permission of using cheap materials, as far as possible make the parts do not waste and waste less cutting. （ 3) Design of stamping parts must be simple shape, reasonable structure, to help simplify the mould structure, simplify the process number, which is the least, the most simple stamping process to complete the whole parts processing, reduce processing with other methods, and is advantageous to the stamping operations, is advantageous for the organization to realize mechanization and automation production, in order to improve labor productivity. （ 4) Design of stamping parts, in can ensure normal use case, make dimensional precision grade and the surface roughness request lower grade, and promotes the exchange of products, reduce scrap, guarantee the stability of product quality. （ 5) Design of stamping parts, as far as possible should be conducive to use existing equipment, process equipment and technological process for machining, and is conducive to extend the service life of die on an article: the quality of the plastic wood stainless steel card buckle and structure is introduced
