① Press on the material. The traditional die design structure is overcome, and the material holding gap is opened on the discharge plate. In this way, the movement of the unloading plate in the stamping is stable, while the material
② Reasonable mold design. The arrangement of blanking sequence may affect the forming accuracy of stamping parts. For blanking of small parts of stamping parts, generally
The blanking of small area is arranged to reduce the impact of blanking force on the forming of stamping parts.
③ Add strong pressure function. Namely, the pressing part of the unloading insert is thickened to increase the pressure on the material at the die side, thus inhibiting the production of stamping parts during blanking
④ The end of the punch edge shall be chamfered or curved. This is an effective way to reduce the blanking force. Reduce the buffer cutting force, which can reduce the stretching of the material on the die side
The effect of material and distortion.
⑤ In daily die production, attention should be paid to maintaining the sharpness of the cutting edges of the punch and die. When the cutting edge is worn, the tensile stress of the material will increase
The trend increases.
