?、?Hold down the material. Overcoming the traditional mold design structure and creating a material holding gap on the discharge plate. In this way, the unloading plate moves smoothly during stamping, while the material can be compressed.

　?、?Reasonable mold design. The arrangement of the cutting sequence may affect the accuracy of stamping parts forming. For the cutting of small parts of stamping parts, generally, a larger area of punching and cutting is arranged first, and a smaller area of punching and cutting is arranged to reduce the impact of punching force on the forming of stamping parts.

　?、?Add strong pressure function. Namely, thicken the size of the unloading insert pressing part to increase the pressure on the material on the concave mold side, thereby suppressing the flipping and twisting deformation of the stamped part during punching and cutting.

　　④ The end of the convex die edge is trimmed with an inclined or curved surface. This is an effective method to slow down the punching force. Reducing buffering and cutting force can reduce the tensile force on the material on the concave mold side, thereby achieving the effect of suppressing the flipping and twisting of stamping parts.

　?、?In daily mold production, attention should be paid to maintaining the sharpness of the punching convex and concave die edges. When the cutting edge is worn, the tensile stress on the material will increase, leading to an increase in the tendency of the stamped part to flip and twist.
