Basic requirements for processing technology of metal stamping parts

Hardware is familiar to us. Among them, metal stamping parts are often used in industrial production or daily life. The metal stamping process is processed by stamping machines, die punches and other equipment, according to the shape required by customers Stamping and forging processing. Sophisticated equipment, convenient operation, high stamping precision, easy to achieve advantages such as mechanization and automation, is currently the most used processing method.

The basic requirements of metal stamping parts processing technology:

1. The processing of metal stamping parts is smaller parts, so in the selection of materials, it is necessary to meet the technical requirements of processed product design and also meet the stamping process and processing requirements after stamping (such as cutting, electroplating, Welding, etc.).

2. For the processing of metal stamping parts, when designing the stamping structure of the parts, a surface with a simple and reasonable structure can be used, which can reduce the number of processed surfaces and the smallest processing area.

3. It is necessary to choose a reasonable method of blank preparation in mechanical manufacturing, which can directly use profile, casting, forging, stamping and welding. The selection of the blank is related to the specific production technical conditions, and generally depends on the production batch, material properties and processing possibilities.

4. The requirements of metal stamping forming performance, in order to improve the processing procedures, stamping deformation and the quality of the parts, the material should have good plasticity, small yield ratio, large plate thickness directivity coefficient, and small plate plane directivity coefficient , The ratio of the yield strength of the material to the elastic modulus is small. For the separation process, the material does not need to have good plasticity, but it should have a certain degree of plasticity. The better the plasticity, the more difficult it is to separate, and the processed products have higher precision.

5. Specify the processing cost of parts with appropriate manufacturing accuracy and surface roughness. The processing cost of metal stamping parts will increase with the improvement of precision, especially in the case of high precision, this increase is extremely significant. Therefore, when there is no sufficient basis, high precision should not be pursued. In the same way, the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface.

The processing technology of metal stamping parts is relatively complicated. In order to ensure that the performance of metal stamping parts can meet the requirements of use, it is necessary to follow the corresponding process requirements to ensure the feasibility of production.
