High precision stamping parts processing technology to understand it

High precision stamping parts processing technology have? 18 years focus on stamping to make small take you know about the author: a raw material performance, high precision stamping parts: there are 4 points about raw material performance testing, 1. Chemical analysis, mainly is to analyze the chemical elements content in raw materials, to confirm whether it can conform to the product performance; 2. Material inspection, the appearance of the material, thickness and quality certificate of compliance with procurement requirements; 3. Hardness testing, generally use the equipment to detect materials such as rockwell hardness tester hardness. 4. Forming performance testing, to need annealing process is added when bending in the production of products, for material bending test, cupping test, etc. ; Second, the high precision stamping process requirements: 1. Precision stamping parts in the design of the structure simple and reasonable processing method as far as possible; 2. Choose the suitable tonnage press so as to meet the requirements of processing technology; 3. Conform to the requirements of the precision stamping formability; 4. Design suitable surface roughness and precision stamping, production inspection specifications; 3, high precision stamping parts stamping oil: the choice of different materials of the stamping materials require different stamping oil, such as: carbon steel sheet is mainly used for some mechanical equipment processing accuracy is not high, pay attention to choose the drawing oil viscosity; Stainless steel is generally requires the use of high oil film strength and good sintering resistance tensile oil; Copper aluminum alloy should be good ductility, can choose oil, oil with good sex of sliding; Simple introduced the high precision stamping parts processing technology, precision stampings, generally for complex process, in order to product performance, will follow the process requirement, ensure the maneuverability.
