Common defects in stamping parts bending
Defects: unqualified bending angle, cracked bending edge, steps at the bending R angle, etc.
1. Unqualified bending angle → The gap between the male and female dies is too large, the matching angle of the male and female dies does not match, and the thickness of the plate material is uneven.
2. Broken bending edge → The gap between the male and female dies is too small; the bending angle is too small; the punching force is too large and the speed is too fast; the plate material is too hard.
3. There is a step at the bending R angle → The bending angle of the male and female dies is too large; the outer R angle is too large; the bending force is too small.
