Boluo hardware stamping parts processing, what are the stamping process technical requirements + stamping accuracy up to 0.01mm

The technical staff responsible for the processing of Boluo hardware stamping parts said that with the improvement of the current quality of life, the hardware stamping parts have penetrated into various fields, and it has been closely related to our lives. So what are the technical requirements for the hardware stamping process? The following hardware masters will introduce the main factors that affect the stamping process: sheet materials, molds, and equipment. 1. The raw material properties of metal stamping parts 1. Chemical analysis and metallographic inspection analyze the content of chemical elements in the material, determine the level and uniformity of the material grain size, and evaluate the free cementite, band structure and non-metallic inclusions in the material Check the material shrinkage, porosity and other defects. 2. Material inspection The materials of stamping parts are mainly hot-rolled or cold-rolled metal plate and strip materials. The raw materials of metal stamping parts should have a quality certificate, which ensures that the materials meet the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts factory can select raw materials for re-inspection as needed. 3. Formability test Carry out bending test and cupping test on the material to determine the work hardening index and plastic strain ratio of the material. In addition, the steel forming performance test method can be carried out in accordance with the thin steel forming performance and test method. 4. Hardness testing The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be tested with other testing instruments. 2. Process requirements of metal stamping parts 1. When designing the structure and shape of parts, metal stamping parts should adopt simple and reasonable surfaces and combinations, and at the same time, try to minimize the number of processed surfaces and the smallest processing area. 2. 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. 3. The requirements of metal stamping forming performance, in order to facilitate stamping deformation and the improvement of the quality of the parts, the material should have good plasticity, small yield ratio, large plate thickness directivity coefficient, small plate directivity coefficient, and material yield The ratio of strength to elastic modulus is small. The separation process does not require a material with good plasticity, but a material with a certain degree of plasticity. 4. Specify appropriate manufacturing accuracy and surface roughness. The cost of metal stamping parts will increase with the improvement of accuracy, especially in the case of high accuracy, this increase is extremely significant. Therefore, high accuracy should not be pursued when there is no sufficient basis. Similarly, the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface.
