Reasonably control the bending springback of stamping parts

In the process of stamping parts, in fact, many different problems are often encountered. As a producer, we need to take corresponding measures to deal with different situations. Among them, one of our more common problems is that we must properly control the amount of bending springback during bending. Next, we will introduce several treatment measures for you. The first point is that we should choose appropriate materials. When designing, we need to take this into consideration. That is to say, under the premise of ensuring the demand for use, materials with lower yield strength, large elastic modulus, small hardening index, and stable mechanical properties should be selected to make stamping products. Secondly, when designing its structure, we also need to consider the size of its bending radius. For the control of this bending amount, we can refer to the corresponding numerical value of different materials for analysis, and then the section moment of inertia of the bending angle can be appropriately increased. In this way, the bending springback can also be reduced to a certain extent. In addition, when changing the bending stress state, we need to make the corners of the bending punch into a partially protruding shape. In this way, when the stamping part is finally bent, it can be reduced by a certain shrinkage. Ammunition. In addition to the above several methods, we can also consider such a method, that is, when bending, we can adjust the stress state of the bending deformation zone by increasing the tensile force in the length direction of the sheet. The tangential compressive stress of the inner layer can be transformed into tensile stress, which solves the problem of large springback of stamping parts. The last method is that when we design the mold, we can appropriately change the shape and size of the mold through the summary of the previous production experience, so that it can exactly meet the shape and size of the stamping part after springback. This method has been well applied.
