Design principles of metal stamping parts

When designing metal stamping parts, in addition to ensuring that the designed metal stamping parts can meet the product use requirements, the processability of the metal stamping parts should also be guaranteed.

The processability of stamping parts refers to the adaptability of stamping parts to stamping processes, that is, whether the designed stamping parts can meet the process requirements of stamping processing in terms of structural shape, dimensional accuracy, etc. Practice has proved that the processability of stamping parts is directly related to the difficulty of processing the parts, the quality of the products, and the labor efficiency and economic benefits.

In stamping production, the processability of metal stamping parts occupies a very important position. Therefore, when designing stamping parts, the following design principles should be followed based on the processability of the products.

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

2. Metal stamping parts must be conducive to improving the utilization rate of materials, reducing the variety and specifications of materials, and using low-priced materials where permitted.

3. Metal stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and optimize the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process. Try not to use other methods for processing, and facilitate stamping operations, and 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 level and surface roughness level requirements of stamping parts lower.

5. The designed stamping parts should be processed using existing equipment, process equipment and process flow as much as possible, which is conducive to extending the service life of the die.
