Stamping parts manufacturers reveal the reasons for the inverted material distortion of stamping parts for you
The main reason for the turning and distortion of stamping parts is the influence of punching force.
   (1) Due to the existence of the blanking gap during punching, the material is stretched on one side of the die (the material is warped upward) and compressed on the side of the punch. When using the unloading plate, use the unloading plate to compress the material to prevent the material on the die side from warping upwards. At this time, the force of the material changes accordingly. As the discharge plate increases its pressing force, the material on the punch side is stretched (compression force tends to decrease), while the material on the concave die surface is compressed (tension force tends to decrease).
   (2) The overturning of the stamping part is caused by the stretching of the material on the die surface. Therefore, when punching, pressing and pressing the material is the key to prevent the punching from turning over and twisting.
