Dongguan Changan hardware stamping processing, technical requirements before production + 17% improvement in assembly production efficiency

The technicians of Dongguan Changan Hardware Stamping have said that some technical requirements about stamping processing determine the quality of stamping products. Do you know all these technologies? The following hardware master has sorted out some relevant information, and let everyone take a look: 1. Chemical analysis, metallographic inspection, analyze the content of chemical elements in the material, determine the level and uniformity of the material's grain size, and evaluate the free penetration in the material. The level of carbon body, band structure and non-metallic inclusions, inspection of material shrinkage, porosity and other defects. 2. Material inspection The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials. The raw materials of metal stamping parts should have quality certificates, which ensure that the materials meet the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts manufacturer can select raw materials for re-inspection as needed. 3. Formability test Perform bending test and cupping test on the material, determine the work hardening index n value and plastic strain ratio r value of the material, etc. In addition, the steel plate formability test method can be in accordance with the thin steel plate formability and test method. get on. 4. Hardness testing The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester.
