The main factors affecting the resilience of stamping parts

In fact, springback is a problem that must be considered for the production of most stamping parts, and it is also a more complicated problem. So far, we have not found a perfect way to completely solve this problem. Therefore, we need to conduct further research and analysis on this issue. So, what are the main factors affecting the resilience of stamping parts? Next, we will briefly analyze this problem for everyone, hoping to help you. The first influencing factor is the material. Because different stamping parts may be made of different PP sheets, the properties of their materials are different, so their strength is different, and their yield strength will also be different. Under normal circumstances, if the yield strength of the sheet is higher, then the rebound phenomenon is more likely to occur. The second influencing factor is the thickness of the material used. This is because in the process of processing and manufacturing stamping products, the thickness of the plate used will have a great difference in its bending performance. Generally speaking, when the thickness of the sheet increases, its rebound phenomenon will gradually decrease. This is because due to the increase in its thickness, the material involved in the plastic deformation increases, so the elastic recovery deformation also increases, which will eventually manifest as a smaller rebound. The third important factor is the shape of the processed stampings. Everyone should know that if the processed shapes are different, the resilience shown will be different. Under normal circumstances, if the shape of the workpiece is more complicated, then an additional shaping process will be added during production to reduce the impact of springback. For some parts with special shapes, springback compensation measures are also needed. In addition, there may be some other factors that will affect the resilience of stamping parts. For example, the blank holder force used in the molding process will also affect the resilience to a certain extent.
