How to solve the unreasonable size of punching parts?

In the production of stamping parts, users will find that they often encounter such problems. When the size is set, why the size of the processed stamping parts will become larger or smaller, or the size of the punch In the case of large differences, we need to analyze this kind of problem, and then take corresponding measures according to the specific reasons. Judging from our rich production experience, if we encounter this kind of problem in the production process, it is best to consider from seven aspects, that is to say, in addition to considering the size of the convex and concave molds of the stamping parts. In addition to factors such as machining accuracy requirements and blanking clearance, the following three aspects need to be considered: The first 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 reason for this problem is mainly due to the instability of stamping parts during bending. Therefore, if you want to solve this problem, you must ensure a suitable blanking gap. If the blanking gap is unreasonable, you should re-adjust it. The second aspect, if the punching edge is worn, it will cause the tensile force on the material to increase, so it will increase the probability of turning and twisting of the stamping part. If there is a problem of turning materials, the punching size of the stamping parts will be reduced. However, if the material is subjected to strong pressure, a certain amount of deformation will occur, and this deformation will cause the size of the punching hole to become larger. If the pressure is reduced, the punch size will also decrease. In the last aspect, 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 bevel or an arc, it is likely to cause turning over and eventually increase the size of the punching hole. In short, in actual work, analysis should be carried out according to the specific situation, and then corresponding measures should be taken to deal with it.
