为了解决高速冲孔压力机在金属薄板冲孔时出现的工件表面平面度差、沿边和搭边处金属断裂、尺寸膨胀等问题,以目前应用最广泛的闭式双点高速精密压力机的偏心主轴为研究对象,介绍了改进压力机主轴的设计原理,设计增加了来自设备本身的主动压料卸料功能,从根本上解决了生产上存在的上述问题。 In order to solve the high-speed punching presses in punching metal sheet surface roughness, edge and edge of the metal rupture, size expansion and other issues, the most widely used in the closed two-point high-speed precision press eccentric The main shaft is the object of study. The design principle of the improved press spindle is introduced. The design adds the function of active material unloading from the equipment itself and fundamentally solves the above problems in production.
