(1) The stamping parts designed must meet the requirements of product usage and technical performance, and can be easily assembled and repaired.
(2) The stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. In the case of permissible use of low-cost materials, as far as possible to make parts without waste and less waste blanking.
(3) The stamping parts designed must be simple in shape and reasonable in structure, so as to simplify the die structure and the number of working procedures, that is, to complete the whole part processing with the least and simplest stamping process, reduce the re-processing by other methods, and be conducive to stamping operation, facilitate the organization of mechanized and automated production, and improve labor productivity.
_The stamping parts designed in this paper, in order to ensure the normal use of the stamping parts, try to make the size accuracy and surface roughness level requirements lower, and is conducive to product interchange, reduce waste products and ensure product quality stability.
(5) The stamping parts designed should be conducive to the use of existing equipment, process equipment and process flow as far as possible, and to the extension of the service life of the die.
