(1) The designed
stamping parts must meet product use and technical performance, and can be easily assembled and repaired.
(2) The designed stamping parts must be beneficial to improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce the consumption of materials as much as possible. Use low-cost materials as far as possible, so that parts can be blanked without waste and with as little waste as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure to facilitate the simplification of the mold structure and the number of processes, that is, to use the least and simplest stamping process to complete the processing of the entire part, reduce the use of other methods, and help The stamping operation facilitates the organization to realize mechanized and automated production to improve labor productivity.
(4) Designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy level and surface roughness level requirements as low as possible, and are conducive to product exchange, reduce waste products, and ensure product quality stability.
(5) The designed stamping parts should be conducive to use the existing equipment, process equipment and process flow to process them as much as possible, and prolong the service life of the die.
