Principles of designing metal stamping parts

Principles of designing metal stamping parts

1. The metal stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

2. Hardware 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 where permitted, and make the parts as waste-free and waste-less as possible.

3. The metal stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and simplify the number of processes, that is, use the least and simplest stamping process to complete the processing of the entire part, and reduce the use of other methods to process. It is conducive to the stamping operation and facilitates the organization of mechanized and automated production to improve labor productivity.

4. The designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy grade and surface roughness grade as low as possible, and it is conducive to product interchange, reducing waste and ensuring stable product quality.

5. Metal stamping parts should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and conducive to the extension of the service life of the die.
