Why does stamping parts have cracking problems

I don't know if you know the specific processing process of stamping parts. In fact, although the processing process of this product is relatively simple, it needs to maintain a better state during the operation. Otherwise, it is easy to cause some unexpected situations. For example, the stamping parts will appear cracks and other undesirable phenomena, which affects their normal use. Below, we take a look at the specific reasons and treatment measures. To solve the problem of cracking, we first need to find out the real cause. In the actual processing process, we can only find that there is more than one reason for the cracking of the metal stamping parts. In general, there are three reasons that can cause the cracking problem. The first factor is the excessive local tensile stress used. Since the product will be affected by internal stress and external impact during processing, it will cause cracking. The other two reasons are: the forming process parameters have not been well implemented, and the flanging forming mold has certain defects in the design. In the molding process, in order to meet the requirements of the process, it is necessary to ensure that the die and the die core must be tightly attached together. In addition, in the molding process, it should also be ensured that the die die and the molding surface remain consistent , So as not to cause cracking problems in stamping parts. So, what measures should we take to prevent this problem in the production process? In view of this problem, we can consider from three aspects. The first point is the drawing process. When drawing, the contact area between the punch and the blank should be increased as much as possible. When designing the structure of the stamping parts, it is best to make the radius of each fillet larger and the depth of each part to be uniform. Third, when designing the mold, a more reasonable design method should be adopted. In short, in order to avoid these problems as low as possible, we must take some effective measures in a targeted manner, so that we can truly prevent the occurrence of defective metal stamping parts and improve the quality of products.
