Harazawa tells you that metal stamping is easy to crack

 In the process of metal stamping parts processing, a little attention, it is possible to make stamping parts appear a variety of different defects. Such as scratches, cracking and other quality problems, today on the Hara Zawa prevention of stamping parts are cracked measures.
The tensile cracking of the stamping parts mainly occurs at the rounded corners, which is due to the excessive local tensile stress leading to local deformation and cracking. In order to reduce this situation, hardware stamping parts manufacturers can prevent it from the following aspects:

   First, choose good quality raw materials for stamping processing.
Two, the fillet radius in line with the production requirements of the premise of the best larger, metal stamping parts processing surface shape in the tensile direction as far as possible to do some uniform.
     
Three, in the design of the design of the shape as simple as possible, the amount of change is as gentle as possible;
Four. The drawing direction of metal stamping parts processing should make the contact area between punch and blank as large as possible. The reasonable shape and holding force of the pressing surface should make the resistance of each part of the pressing surface uniform and moderate, reduce the drawing depth, open process holes and notches, etc.
