(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 varieties and specifications of materials, and reducing the consumption of materials as much as possible. If allowed, materials with low price shall be used to make the parts blanking without waste and with less waste as far 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 the number of processes. That is, the minimum and simplest stamping process is used to complete the processing of the whole part, and other methods are used to reduce processing. It is also conducive to stamping operations, and it is convenient to organize and realize mechanized and automatic production, so as to improve labor productivity.
(4) Under the condition of ensuring normal use, the designed stamping parts should have lower requirements on dimension accuracy grade and surface roughness grade as far as possible, which is conducive to product interchange, reducing waste products and ensuring stable product quality.
(5) The designed stamping parts shall be conducive to the use of existing equipment, process equipment and process flow to process them as much as possible, and to the extension of the service life of the die.
