What are the factors that affect the accuracy of precision stamping parts? 'Hardware'

The main factors that affect the accuracy of precision stamping parts are as follows: 1. The quality of raw materials for precision stamping parts is inferior. 2. Multi-process precision stamping parts due to improper adjustment of the previous process or wear of rounded corners, breaking the principle of equal volume when deformed, and causing size changes after punching. 3. Due to the poor positioning of precision stamping parts during operation, or the poorly designed positioning mechanism, the blanks move during the punching process. Or the inaccurate positioning caused by the defects (prismatic degree, missing edges, etc.) of the shearing piece can cause the size to be out of tolerance. 4. The blanking sequence of precision stamping parts is wrong. 5. The size of the edge of the precision stamping die is out of tolerance. 6. The springback during the punching process of the precision stamping, and the shape of the part in the previous process is inconsistent with the shape of the supporting surface of the mold working part in the next process, which makes the stamping part. Deformation occurs during the blanking process, and elastic recovery occurs after the blanking process, which affects the dimensional accuracy. The above is the introduction of the hardware author on the factors affecting the accuracy of precision stamping parts. I hope it will be helpful to you. If you need to know more, welcome to consult:
