The primary basic processes of stamping are blanking, punching, zigzag and deep drawing.(1) blanking and punching blanking and punching are processes to separate the blank.The process of blanking and punching is completely the same except for different purposes. When blanking, the separated part is the product, and the rest of the surrounding is the waste; punching is to obtain holes, the punched

Hardness test of metal stamping parts Rockwell hardness tester is selected for hardness test of metal stamping parts. The small stamping parts with disordered shape can be used to test the small plane and can not be tested on the ordinary Rockwell hardness tester. Metal stamping processing includes stamping, zigzag, drawing, forming, finishing and other processes.Hardness test of metal stamping pa

I. in the daily processing of metal stamping parts, there will be problems such as large or small punch size and large difference between punch size and punch size.2. When the cutting edge is worn, the tensile stress of the data increases, and the tendency of turning over and distortion of the stamping parts increases. When turning over occurs, the punching dimension will be smaller.3. The strong
