(1) the design of the 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, 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) the design of the stamping parts must be simple shape, reasonable structure, in order to help simplify the mould structure, simplify the process, which is less, the simpler the stamping process of a complete machining of the parts, reduce the 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, for the cover can be normal use, make dimensional precision grade and the surface roughness request lower grade, and promotes the exchange of products, reduce waste, to protect the product quality is stable.
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 helpful to extend the service life of die.
