What are the common problems in metal stamping
2020-05-05 701
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
