What are the technical requirements for high-precision automotive stamping parts processing technology?
1. Raw material performance of high-precision stamping parts: There are 4 points about raw material performance testing, 1. Chemical analysis, mainly to analyze the content of chemical elements in raw materials, to confirm whether it can meet the performance of the product; 2. Material inspection, the appearance of the material , whether the thickness, quality certificate, etc. meet the procurement requirements; 3. Hardness testing, generally using Rockwell hardness tester and other equipment to test the hardness of materials; 4. Forming performance testing, for products that need to be bent, annealing process is added during production, for The material is subjected to bending test, cupping test, etc.;
2. Process requirements for high-precision automotive stamping parts: 1. When designing precision stamping parts, try to adopt a simple and reasonable processing method; 2. Select a press with a suitable tonnage to meet the processing technology requirements; 3. Meet the requirements of precision stamping parts Forming performance requirements; 4. Design appropriate surface roughness and stamping accuracy, and make inspection specifications;
3. Selection of stamping oil for high-precision stamping parts: stamping materials of different materials require different stamping oils. For example, carbon steel plates are mainly used for some machinery and equipment with low processing accuracy requirements. Pay attention to the viscosity of the drawing oil; stainless steel material The general requirements for the use of tensile oil with high oil film strength and good sintering resistance; copper and aluminum alloy materials should have good material ductility, and oily and good sliding oil can be selected;
The technical requirements for the processing of high-precision stamping parts are briefly introduced. Precision stamping parts are generally complex processes. For the performance of the product, the process requirements must be followed to ensure operability.
