Production improvement process of metal automobile stamping parts

In the processing of hardware parts, automobile stamping parts manufacturers have certain regulations and principles for every part and every process. Stamping workers perform stamping in accordance with a certain work sequence. Stamping parts processing companies are looking for more optimal factors. The stamping process has been greatly improved, let’s take a look; the general production sequence of auto stamping factory parts includes: stamping, cleaning, welding, degreasing, cleaning, electrophoresis. Aiming at the improvement of the stamping process of auto parts, the improvement of production efficiency in the stamping process, the protection of molds, the improvement of stamping quality, etc., stamping plants have developed many methods, including the following: For the shape, a simple and reasonable structure should be used, and at the same time, the number of processing surfaces and the processing area should be minimized as much as possible. 2. The stamping materials used in automobile stamping parts must not only meet the technical requirements of product design, but also meet the requirements of the stamping process and the processing requirements of cutting, electroplating, cleaning and other processes after stamping. 3. The requirements of metal stamping forming performance. In order to facilitate the improvement of stamping deformation and the quality of stamping parts, the material should have good plasticity, large plate thickness directivity coefficient, small plate plane directivity coefficient, yield strength and elasticity of the material. The ratio of the amount is small. For the separation process, it is not necessary for the hardware material to have good plasticity, but it should have a certain degree of plasticity. The better the plasticity, the more difficult it is to separate. 4. Choose a reasonable method of mechanical manufacturing blank preparation, 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. 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, so the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface. 6. The stamping oil used in the processing of auto parts should meet the process requirements. The special high-quality stamping oil can significantly improve the processing environment and improve the accuracy of the workpiece.
