What are the common stamping methods of stamping parts?

(1) reasonable mold design. In progressive die, the arrangement of blanking sequence may affect the forming accuracy of stamping parts. In order to reduce the influence of blanking force on the forming of stamping parts, the blanking with larger area is usually arranged first, and then the blanking of small area is arranged.
(2) press the material. It overcomes the traditional mold design structure, that is, when the mold is closed, the material can be compressed. For the key forming parts, the discharge plate must be made into an inlaid structure, so as to solve the wear of the pressing part of the discharge plate caused by long-time stamping, and the material can not be compressed.
(3) add the function of strong pressure. In other words, the size of the pressing part of the discharging insert is thickened to increase the pressure on the material at the die side, so as to prevent the stamping parts from turning over and twisting during blanking.
(4) the end of punch edge is trimmed with inclined plane or arc. This is an effective way to slow down the blanking force. By reducing the buffer cutting force, the drawing force on the side of die can be reduced, so as to prevent the stamping parts from turning over and twisting.
(5) in the daily die production, attention should be paid to maintaining the sharpness of punch and die edge. When the cutting edge is worn, the tensile stress of the material will increase, and the stamping parts tend to turn over and twist.
(6) unreasonable blanking clearance or uneven clearance is also the cause of stamping parts turnover and distortion, which needs to be overcome. A
