Handling of common specific problems in the production of stamping parts

In fact, in the process of producing and processing various stamping parts, it is often encountered that the size of the punching hole is too large or too small, and the size of the punch is quite different. Therefore, in order to avoid such a situation, in the process of processing stamping parts, it is necessary to consider factors such as the design dimensions of the molding convex and the concave mold, the processing accuracy, and the blanking gap. In addition, the following aspects should be considered at the same time: First, if the punching edge is severely worn, the force on the material during processing will increase, and the stamping part will turn over, The possibility of distortion will greatly increase. And if the material is turned over, then the punching size will be reduced at this time. Second, in the process of processing, the raw materials of stamping parts may undergo certain plastic deformation after being subjected to pressure. This will cause the punching size to become larger, and when the pressure is reduced, the punching size of the single-column hydraulic machine will become smaller. Thirdly, consider the specific shape of the end of the punch's edge. Under normal circumstances, if the end is trimmed with a bevel or arc, the punching force is slowed down, so the stamping part is not prone to turning over, twisting and other problems. Therefore, the punching size will become larger at this time. If the end of the punch is flat, the size of the punching hole will be relatively small. In short, in actual production, for different problems, we need to analyze according to the specific situation, so as to find a way to solve the problem. It should be noted that if the stamping parts are relatively small, special tools should be used instead of directly feeding or picking up the parts by hand. Moreover, during the entire production process, operators and mold repairers are not allowed to put their hands into the mold to work.
