How to deal with the problem of punching size of stamping parts

In the production of stamping parts, users will find that they often encounter such problems. When the size of the set size is set, why the size of the processed stamping parts will become larger or smaller, or the size of the punch Different and larger situations, we need to analyze this kind of problem, and then adopt the corresponding method according to the detailed reason. Judging from our rich production experience, if we encounter this kind of problem in the production process, then we should consider it from seven aspects, which means that in addition to considering the size and processing accuracy of the convex and concave molds of the stamping parts In addition to the requirements and blanking gaps and other factors, the following three aspects need to be considered: One aspect may be caused by some burrs formed during blanking. If this is the case, we should check whether the blanking gap is reasonable. We believe that the main reason for this problem is that the stamped parts are unstable during bending. Therefore, if you want to deal with this problem, you must ensure a suitable blanking gap, if the blanking gap is unreasonable, it should be adjusted from the beginning. The second aspect is that if the punching edge is worn, it will cause the increase of the tension on the material, so it will increase the probability that the stamping part will appear to be turned and distorted. If there is a problem of turning materials, the punching size of the stamping part will be reduced. However, if the material is subjected to strong pressure, certain deformation will occur, and this deformation will result in an increase in the size of the punching hole. If the pressure drops, the size of the punching hole will decrease accordingly. After all, check whether there is any abnormality at the end of the punch edge. If some problems are found at the end during the production of stamping parts, such as a slope or an arc, it is likely to cause turning over, and eventually the size of the punching hole will become larger. In short, in practical work, analysis should be carried out according to detailed conditions, and then corresponding methods should be adopted.
