What are the causes of chip jumping crush caused by die stamping parts
1. When the clearance is too large, control the machining accuracy of the concave and convex die or modify the design clearance.
2. If the material is not properly fed, trim the material belt and clean the mold in time when it is sent to the appropriate position.
3. Stamping oil drops too fast, oil stains, control stamping oil amount or replace oil to reduce viscosity.
4. The mold is not demagnetized, and it should be demagnetized after study (pay more attention to the iron material).
5. Punch wear, chips pressed on the punch, need to research punch edge.
6. The punch is too short and the length of the insert die is not enough. It is necessary to adjust the length of the insert die.
7. The material is hard, the punching shape is simple, it can load the top out or trim the inclined plane or arc in the end face of the punch edge to reduce the end face of the punch edge and the fitting area.
Emergency measures are: reduce the amount of research on the edge of the concave die, increase the surface roughness of the straight edge of the concave die, use a vacuum cleaner to suck the waste, reduce the impact speed, slow down the chip jumping.
