Stamping design principles for metal fittings


Punching process is to use the power of conventional or special stamping equipment to directly deform the sheet in the mold and deform it to obtain a certain shape , Size and performance production technology of product parts.
Punching design principles for stamping:
(1) The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
(2) The stamped parts must be designed to improve the utilization of metal materials, reduce the variety and specifications of materials, and reduce 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 The stamping operation facilitates the organization to realize mechanization and automated production to improve labor productivity.
(4) The designed stamping parts should ensure that the dimensional accuracy level and surface roughness level are as low as possible under the conditions of normal use, which is conducive to the interchange of products, reduces waste products, and ensures stable product quality.
(5) The stamping parts designed shall be conducive to the use of existing equipment, process equipment and processes as much as possible, and it will be helpful to extend the service life of the die.
