High-speed punch press processing of common defects and solutions

   The following are some common defects and solutions of high-speed punching machine processing:
Defect one: excessive burrs on punched parts
    Reason: mold edge wear, unreasonable gap, etc..
    Solution: timely grinding or replacement of the mold edge, adjust the reasonable gap.
Defect 2: Deformation of punched parts
    Reason: Insufficient pressing force, unreasonable mold structure, etc.
    Solution: Increase the pressing force and optimize the die structure design.
Defect 3: Dimensional deviation
    Cause: Inaccurate positioning of the mold, failure of feeding mechanism, etc.
    Solution: Check and correct the mold positioning device, repair the feeding mechanism.

Defect 4: Surface scratches
    Reason: Rough surface of the mold, foreign objects in the feeding process, etc.
    Solution: Polishing the surface of the mold to make it smooth, and cleaning the foreign matter in the feeding path.
Defect 5: Breakage of punched parts
    Cause: Problems with material properties, excessive punching force, etc.
    Solution: Replace the material with suitable performance, adjust the process parameters to reduce the punching force.
Defect 6: Waste material jumping back
    Reason: The straight wall of concave die edge is too high, and the clearance between scrap and concave die is too small.
    Solution: Reduce the height of the straight wall of concave mold edge, and increase the clearance between scrap and concave mold appropriately.
