Design principles of stamped parts

(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 specification of materials, and reducing the consumption of materials as much as possible. Where possible, inexpensive materials are used to make parts as scrap-free and scrap-free as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, using the least and simplest stamping process to complete the processing of the entire part, reducing the processing of other methods, and conducive to stamping operations, facilitating the organization of mechanized and automated production to improve labor productivity.
(4) The designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy level and surface roughness level requirements lower, and facilitate the exchange of products, reduce scrap, and ensure stable product quality.
(5) The designed stamping parts should be conducive to the use of existing equipment, process equipment and technological flow to process them as much as possible, and conducive to the extension of the service life of the die.
