The punch is a metal part on the stamping die, also known as punch, punch or punch. It is installed on the die for continuous punching and punching operations, so that the processed materials are separated or plastically deformed to obtain the desired finished or semi-finished products.

Drawing die

    Die punches generally use high-speed steel and tungsten steel as materials. There are high-speed steel punches and tungsten steel punches. High-speed steel is a more commonly used material. Tungsten steel materials are generally used for punching and shearing molds with higher requirements. In the production process of tungsten steel die punches, sometimes the punch material breaks, what are the factors that cause it to burst? How should our application respond. Let's take a look together.

    1. The closing height is too low and the punch edge is too long. Solution: Adjust the closing height so that the punching edge fits the length.

    2. Due to improper material positioning, one side of the tungsten steel punch is cut off and broken due to uneven stress. Solution: Adjust the positioning or feeding device.

    3. The scrap of the lower die blocks the blade, causing the punch to break. Solution: Re-drill large blanking holes to make blanking smooth.

    4. The fixed part (clamp) of the punch is offset from the guide part (punch). Solution: Trim or re-thread the stopper to make the punch go up and down smoothly ..

    5. The poor orientation of the punching plate causes stress on one side of the punch. Solution: Re-adjust the gap between the playing boards.

    6. The punching edge is too short, use a punching plate to dry. Solution: Replace the punch again and increase the blade length.

    7. This fist cannot support well and moves up and down. Solution: Fix the punch again to prevent it from moving up and down.

    8. The punch is not sharp. Solution: Re-grind the cutting edge.
