A precision press is a mechanical equipment used to process materials. During the processing of a precision press, the rebound and elastic deformation of materials are important issues that need to be considered and dealt with. These two factors directly affect the shape accuracy and dimensional accuracy of the final product.
The rebound of the material means that the material will partially or completely return to its original shape after being subjected to pressure and deformation. This is because the material itself has a certain elasticity. Considering the occurrence of this situation, we added overshoot when designing the mold. , Overshoot means that during the processing process, the upper mold is a certain distance below its lowest point.
In addition, the control system of the precision press can monitor parameters such as pressure and displacement in real time, and can accurately control elastic deformation. By reasonably adjusting the control system parameters, the impact of elastic deformation can be reduced and the processing accuracy of materials can be ensured.
In order to better handle the springback phenomenon, precision press molds are usually designed with rebound plates. The function of these plates is to exert additional pressure on the material through the rebound plate after the upper mold pressure is withdrawn, so that the material can better return to its original shape.
