Analysis of several problems in the production process of stamping parts

If the stamping parts are bent and deformed, then we believe that this is due to the fact that the gap force and the reaction force are not in the same line during the process of applying the force, resulting in a moment. In response to this situation, we need to take appropriate measures to deal with it. For example, we need to properly adjust the blanking gap to make it reasonable. Of course, we can also take other methods to deal with it. For example, we can add a blanking plate or a holding plate to the stamping die used, and make it contact with the blanking plate plane and maintain a certain pressure. Of course, if the cutting edge of the die is checked and it is found that there is a back taper, the die needs to be trimmed in time to restore it to normal. In the actual processing of stamping parts, we will encounter many other problems, let's introduce a few more situations. During the punching process, it was found that the dimensional accuracy of the periphery of the workpiece and its inner hole had changed. What is going on here? After analysis, we divided into possible reasons: 1. Positioning pins, stop pins, etc. have changed or worn too much; 2. During operation, due to lack of concentration, the workpiece shifted left and right; 3. The material used has lower dimensional accuracy and so on. Another situation is that in the process of bending the stamping part, a large number of burrs appear in the bending part. At this time, we can take such measures to deal with: 1. It is best to keep the bending direction perpendicular to the fiber direction of the material during the bending process; 2. Increase the bending radius appropriately, and enlarge the circle as much as possible when conditions permit. Corner radius; 3. Ensure that its surface is clean and smooth. The above is the analysis of several problems that may be encountered in the production process of stamping parts for everyone. I hope that after this sharing, we can bring some help, and we can avoid similar problems as much as possible in the future processing. The problem.
