stamping parts have entered our career in a hurry, our requests for stamping parts are getting higher and higher, and the skill requirements for stamping parts processing are getting higher and higher. Let's take a look at what skills are required for stamping parts processing. .
1. Chemical analysis and metallographic analysis analyze the content of chemical elements in the data, determine the grain size level and average level of the data, assess the level of free cementite, band structure and non-metallic impurities in the data, review the data shrinkage, Fluffy and other disadvantages.
2. Data review The important data of stamping parts processing is hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials. The original materials of metal stamping parts should have quality certification, which guarantees that the data meets the requirements of the specified skills . When there is no quality certificate or other reasons, the manufacturer of metal stamping parts can choose the original materials for re-inspection as needed.
3. Forming function experiment: Conduct zigzag experiment and cupping experiment on the data to determine the work hardening index n value and plastic strain ratio r value of the data. In addition, for the steel plate forming function test method, the thin steel plate forming function can be divided according to the experimental method Scheduled.
4. Hardness testing The hardness testing of metal stampings adopts Rockwell hardness tester. The small stamping parts with complicated shapes can be used to test the plane is very small, but can not help testing on the general desktop Rockwell hardness tester. Metal stamping parts have the characteristics of thin, uniform, light and strong. Shenzhen Dafu Precision Industry Co., Ltd. specializes in the production of various metal stamping parts, specializing in the research and development and production of metal stamping parts. It adopts precise mold processing to make the metal stamping parts more accurate Up to the micron level.
