After bending, the end face of the workpiece bulges or is uneven
-
- 197
Cause: when bending, the outer surface of the material is pulled in the circumferential direction to produce shrinkage deformation, and the inner surface is pressed in the circumferential direction to produce elongation deformation, so the bending end face bulges along the bending direction.
terms of settlement:
- The punch and die shall have sufficient pressure at the final stage of stamping.
- Make the die fillet radius corresponding to the workpiece fillet.
- Add process improvement.
