What to do if burrs occur in the precision metal stamping process-hardware

In the production process of precision metal stamping, because the principle of the die is cold stamping, punching and cutting, so in the production process, the metal material will often have burrs from precision metal stamping after stamping and forming. It affects the appearance, accuracy, and assembly. How to solve the problem of burrs in the manufacturing process? (1) The mold gap is too large or uneven, readjust the mold gap; (2) The mold material and heat treatment are improper, resulting in the inverted cone of the die or the cutting edge is not sharp. The material should be selected reasonably. The material of the mold working part should be made of cemented carbide and heat treated The method is reasonable; (3) Stamping wear, grinding punch or insert; (4) The punch enters the concave mold too deeply, adjust the depth of the punch into the concave mold; (5) The guide structure is not precise or the operation is improper, and the inner guide of the mold is repaired The guiding accuracy of the column guide sleeve and the punching machine is to standardize the punching operation. Hardware, 15 years of craftsmanship focused on precision metal stamping, more than 20 Ru0026D and design engineers, product accuracy can reach 0.01MM, 16 quality inspection procedures are firmly checked for quality. Choose, choose rest assured!
