(1) design of pressing must satisfy the product use and technical performance, and can be easily assembly and repair match means.
(2) the stamping design must be beneficial to improve the utilization rate of metal materials, reduce the materials and the variety of specifications, reduce material consumption. In the permission of the low prices of materials, as far as possible the parts do no waste and less waste cutting.
(3) the stamping design must be simple shape, reasonable structure, in order to be helpful for mould structure, simplify the process simplified number, which is at least, the most simple punching process to complete the entire parts processing, reduce, reuse other processing methods, and to facilitate the stamping operation, organized and realize mechanization and automatic production, in order to improve the productivity of Labour.
(4) design of pressing, in can guarantee the normal use and try to make size precision grades and surface roughness level required some low, and to facilitate the exchange of product, reduce the waste, and to ensure the product quality is stable.
(5) design of pressing, should be advantageous to try to use the existing equipment, process equipment and process flow of the processing, stamping and to facilitate the use of the life extension.
