What Are the Technical Requirements for Metal Stamping Parts?

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, the corresponding process requirements must be followed to ensure the feasibility of production.

First of all, when designing the structure and shape of metal stamping parts, simple and reasonable surfaces and their combinations should be used at the same time to minimize the number and area of machined surfaces.

The second is the manufacturing selection of metal stamping parts. In mechanical manufacturing, a reasonable blank preparation method can be selected. Profiles, casting, forging, stamping and welding can be directly used. The selection of blanks is related to the specific production process conditions and generally depends on the production batch. , material properties and processing possibilities.

The third is the requirements for the forming performance of metal stamping parts. In order to improve the stamping deformation and product quality, the material should have good plasticity, a small yield ratio, a large plate thickness directional coefficient, a small plate surface directional coefficient, and the material yield strength and elasticity. The modulus ratio is small. The separation process does not require a material with good plasticity, but the material has some plasticity.

Fourth, the appropriate manufacturing precision and surface roughness are specified. The cost of metal stamping parts will increase with the increase of precision, especially in the case of high precision. This increase is very significant. Therefore, the pursuit of high precision is the same Without sufficient basis, the surface roughness of metal stamping parts should also be properly specified according to the actual needs of the surface.
