In this article, let's look at the impact of the rationality of stamping die clearance on the quality of metal stamping parts. As we all know, a reasonable stamping die clearance can make the blanking achieve better section quality, smaller blanking force, higher dimensional accuracy and higher die life.
1.if the gap of the metal stamping die is small, although the punching quality is good, the wear of the stamping die is more serious, which greatly reduces the service life of the punching die, and is easy to cause the fracture of the punch.
2. if the gap of the stamping die is too large, the burr of the metal stamping part will be relatively large, and the quality of the product is poor;
3.the gap of the metal stamping die is too large or too small are easy to produce adhesion on the punch material, resulting in stamping with material, too small gap is easy to form a vacuum between the bottom of the punch and the sheet material and waste rebound.
4.a reasonable gap in the metal stamping die can extend the life of the die, the discharge effect is good, the burr and flanging are reduced, the plate is kept clean, the aperture is consistent, the plate will not be scratches, the number of grinding times is reduced, the plate is kept flat and straight, and the punching position is accurate.
