The reasons and improvement measures for the burrs of die stamping parts are:
1) The cutting edge is worn or chipped, and the quenching hardness is low, and the cutting edge needs to be trained
2) If the clearance is too large, the effect is not obvious after training the knife edge, and it is necessary to further control the processing accuracy of the convex and concave mold or modify the design clearance;
3) The gap is unreasonably shifted up and down or loose, and the blanking gap needs to be further adjusted to confirm the wear of the template hole or the processing accuracy of the molded part;
4) The mold is misaligned up and down, it is necessary to replace the guide or re-assemble the mold
