Technical guidelines for metal stamping parts

The reason for the change of the workpiece in the process of metal stamping parts: the technical requirements of metal stamping parts are developing in the direction of complex structure, increased block size, more parts on related sides, increased load-bearing capacity and strict internal stress restrictions. This requires and promotes the development of special stamping forming technologies such as hydroforming, precision forming, explosive forming, spinning forming, dieless forming, laser forming and electromagnetic forming technology.

Hardware stamping parts are widely used in various fields of our lives, including some electronic devices, auto parts, decorative materials and so on. The design of metal stamping parts must meet these basic requirements. On this basis, certain design principles or indicators are required:

1. Satisfy product use and technical performance, and can be easily assembled and repaired.

2. It is 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 shape is simple and the structure is reasonable, which is conducive to simplifying the mold structure and simplifying the number of processes, that is, the smallest and simplest stamping process is used to complete the processing of the entire part, reducing the use of other methods to process, and is beneficial to the stamping operation. Facilitate the organization of mechanized and automated production to improve labor productivity.

4. 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. The design of 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 is conducive to the extension of the service life of the die.
