Analysis of chip jumping and crushing of continuous die stamping parts

Netizens asked: What are the reasons for the chipping and crushing of the continuous die stamping parts, and what countermeasures should be taken? Expert reply: The reasons for the chipping and crushing of the continuous die stamping parts, the corresponding countermeasures are the following methods. ☆ When the gap is too large, control the processing accuracy of the convex and concave molds or modify the design gap; 　　☆ If the material is not properly fed and needs to be sent to the appropriate position, trim the strip and clean the mold in time; 　　☆ The punching oil drips too fast, the oil is sticky, and the punching oil drips　　☆ The mold is not demagnetized and must be demagnetized after training (more attention should be paid to the punching material); 　　☆ The punch is worn and the chips are pressed on the punch, and the punch knife edge needs to be trained; 　　☆ The punch is too large Short, the length of the inserted die is insufficient, the length of the punch blade into the die needs to be adjusted; 　　☆ The material is hard, and the punching shape is simple. It can be ejected or trimmed at the end of the punch blade to reduce the punch blade. The bonding area between the end face and the chip material.
