Reasons and solutions for turning and twisting during precision stamping and bending

With the development of society, various industries have increasingly higher requirements for metal stamping parts, including the appearance of stamping parts. In the process of precision stamping and bending, some undesirable problems, such as turning over and twisting, are prone to occur. So what is the reason for this kind of situation? This article summarizes the experience to share with you. 1. The burrs of stamping parts caused by blanking are caused. Need to study the cutting edge, and pay attention to check whether the blanking gap is reasonable. 2. Turning, distortion and deformation of the stamping parts have occurred during blanking, resulting in poor forming after bending, which needs to be dealt with from the blanking and unloading station. 3. It is caused by the instability of stamping parts during bending. Mainly for U-shaped and V-shaped bending, the positioning of the stamping parts before bending, the guidance during the bending process, and the pressing of the material during the bending process, to prevent the stamping parts from slipping during bending. As for why there will be twisting distortion during precision stamping and bending and how to solve it? I believe everyone has already understood. The main reason is the influence of the punching force and the unreasonable blanking gap and uneven gap. Through the above methods, these problems can be effectively solved and the stamping parts can be prevented from turning over and twisting.
