In the process of precision stamping production, the quality of bent parts is a problem that we are very concerned about. A common quality problem with bent parts is the appearance of cracks. The reasons for the cracks are: 1. The bending radius of the punch is too small. 2. One side of the rough burr is on the outside of the curve. 3. The plasticity of the sheet is low. 4. The hardened layer of the blank is too large when blanking. The solutions are: 1. Appropriately increase the bending radius of the punch. 2. Place the burr on the inner side of the bend. 3. Use diameter annealing or materials with better plasticity during stamping. 4. The bending line is perpendicular to the fiber direction or 45 degrees.
