1. Raw material properties of high-precision stamping parts
①Chemical analysis mainly analyzes the content of chemical elements in raw materials to confirm whether they can meet product performance;
②Material inspection, material appearance, thickness and quality certificate to see if they meet the procurement requirements;
③ Hardness testing: Material hardness is generally tested using Rockwell hardness tester and other equipment;
④ Forming performance testing: Add annealing technology to products that need to be bent during the production process, and conduct bending tests, cupping tests, etc. on the materials. ;
2. Process requirements for Petrol Car stamping parts
① When designing precision stamping parts, try to use processing methods with simple and reasonable structures;
②Choose a press of appropriate tonnage to meet the processing technology requirements;
③Meet the forming performance requirements of precision stamping parts;
④ Design appropriate surface roughness and stamping accuracy, and produce and inspect 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 in some mechanical equipment that do not require high processing accuracy. Pay attention to the viscosity of the tensile oil; stainless steel generally requires the use of tensile oil with high strength and good sintering resistance; alloy materials such as copper and aluminum should have good Due to the ductility of the material, oil with good oiliness and good sliding properties can be used;
The processing technology requirements of high-precision stamping parts are briefly introduced. Precision stamping parts generally require complex processes. For the performance of the product, the process requirements must be followed to ensure operability.
