How to solve the distortion of metal stamping parts?

With the refinement of industrial electronics, various industries have higher and higher requirements for stamping parts, including the shape of metal stamping parts. In the process of punching the shape of metal stamping parts, it is easy to produce turning and distortion, which affects the quality of the product. Now I will share my experience with you: Why do metal stamping parts have turning distortion? How to solve it? In the die, the outer shape of the punched part is formed by punching the leftover material around the punching part. The main reason for the turning and distortion of stamping parts is the influence of punching force. When punching, due to the existence of the punching gap, the material is stretched on one side of the die (the material is warped upward) and compressed on the side of the male die. 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). The overturning of the stamping part is caused by the stretching of the material on the die surface. Therefore, when punching, pressing and compressing the material is the key point to prevent the punching from turning over and twisting. The reasons and solutions for turning and twisting of metal stamping parts: 1. It is caused by the burrs of the stamping parts during punching. Need to study the cutting edge, and pay attention to check whether the blanking gap is reasonable. 2. The turning, distortion and deformation of the punched parts have occurred during the punching process, which leads to poor forming after bending, which needs to be solved from the punching and unloading station. 3. It is caused by the instability of stamping parts during bending. Mainly for U-shaped and V-shaped bending. To deal with this problem, guiding the stamping parts before bending, guiding during the bending process, and pressing the material during the bending process to prevent the stamping parts from slipping during bending are the key points to solve the problem. After reading this article, I believe everyone has some understanding. The main reason for the distortion of the metal stamping parts is the influence of the blanking force and the unreasonable blanking gap and uneven clearance. The above methods can effectively solve these problems and avoid the stamping parts from turning and twisting.
