(1) The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
(2) The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing material consumption as much as possible. Use low-cost materials where possible, and make parts as scrap-free and blank as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and simplify the number of processes, that is, use the least and simplest stamping process to complete the processing of the entire part, reduce the need for other methods to process, and facilitate the stamping operation. , to facilitate the organization of mechanized and automated production to improve labor productivity.
⑷ For the designed stamping parts, under the condition of normal use, try to make the dimensional accuracy grade and surface roughness grade lower, which is conducive to the exchange of products, reduces waste, and ensures stable product quality.
⑸ The designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and will help to prolong the service life of the stamping die.
