Design principles of metal stampings
⑴The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
⑵The design of stamping parts must be conducive to improving the utilization of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. When possible, use low-cost materials to make parts as waste-free and waste-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, to complete the processing of the entire part with the least and simplest stamping process, reduce the use of other methods, and facilitate stamping operations , It is convenient for the organization to realize mechanization and automated production to improve labor productivity.
⑷The designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy level and surface roughness level as low as possible, which is conducive to the interchange of products, reducing waste products and ensuring stable product quality.
(2) The stamping parts designed should be conducive to the use of existing equipment, process equipment and process as much as possible, and it is beneficial to the extension of the service life of the die.
