Reasons and solutions for easy breakage of hexagonal punches (1)

    Introduction: The phenomenon of punch breakage will occur when using stamping dies. The following will introduce you to the common causes of punch breakage:

    1. The closing height is too low, and the cutting edge of the punch is too long.

      Solution: Adjust the closing height to make the punch blade a proper length.

    2. Improper positioning of the material causes the punching tungsten steel punch to cut a single side and break due to uneven force.

      Solution: adjust positioning or feeding device

    3. The scrap of the lower mold blocks the knife edge and causes the punch to break.

      Solution: re-drill the large blanking hole to make the blanking smooth

    4. The fixed part (splint) of the punch is offset from the guiding part (beating board).

      Solution: repair or re-cut into the block to make the punch up and down smoothly

    5. Poor guide of the punching board, causing unilateral force on the punch.

      Solution: re-repair the boarding gap

    6. The punch blade is too short, and it is dry with the punch.

      Solution: Replace the punch and increase the length of the knife edge

    7. The punch is not fixed well and moves up and down.

      Solution: re-fix the punch so that it cannot move up and down

    8. The cutting edge of the punch is not sharp.

      Solution: re-grind the cutting edge
