Progressive die stamping products have the cause of chip crush: ignition barrel price

A. large gap;B. improper feeding;C. the stamping oil drops too fast and the oil is sticky;D. The mold is not demagnetized;E. The punch is worn and the chip is pressed onto the punch;F. The punch is too short and the insert die length is insufficient;G. Hard material and simple punching shape;H. Emergency measures.

Solutions:

A. Control the machining accuracy of convex and concave die or modify the design clearance;B. when it is sent to the proper place, trim the material belt and clean the mold in time;C. Control the amount of stamping oil drop, or change the type of oil to reduce the viscosity;D mold, research and repair must be demagnetization (iron punching material more attention);E. Research and repair punch edge;F. Adjust the length of the punch blade into the die;G. Change materials and modify design.Punch edge into the end face to eject or trim the slope or arc (pay attention to the direction).Reduce the laminating area between the end face of the punch edge and the chip;H. Reduce the sharpness of the die edge, reduce the research amount of the die edge, and increase the roughness of the surface of the straight edge of the die (covering).Reduce the impact speed, slow down the chip jumping.
