Abstract：

Aiming at the shortcomings of traditional filling compound wedge structure, the improvement methods were put forward. In the traditional filling compound wedge structure, the movable drive slider and movable punch were driven by the rigid wedge panel and returned by nitrogen cylinders, and because of high frequent and high-speed motion and work, the serious wear of wedge panel was caused which affected the accuracy of wedge structure. Therefore, the traditional filling compound wedge structure was improved, the working and return strokes were driven by the cylinder for movable drive slider and movable punch, which solved the problem of unreliable positioning for part caused by the wear of wedge panel when the traditional filling compound wedge structure was applied. In addition, the auxiliary nitrogen cylinder was used to carry out the working stroke of movable punch, which also solved the problem of slow stamping production rhythm when the cylinder drove the movable punch.
