摘　　要：针对板料冲裁切边加工时机床所产生的强烈冲击和振动,本文提供了一种用于侧移台液压机使用的上置式缓冲装置,创新的采用大行程缓冲缸配合液压系统和电气系统实现缓冲点的自动调节,使得液压机由冲裁工艺载荷平稳过渡到缓冲载荷。同时采用快速卸压装置使主缸内积聚的液压能和机身弹性变形能迅速受控释放,消除滑块突然过冲现象,有效减轻液压机冲裁加工时产生的冲击和振动。Due to the strong impact and vibration generated by the machine tool in the blanking and edge cutting process of sheet metal,a kind of upper buffer device used for the side-moving table hydraulic press has been provided in the text.The large stroke buffering cylinder has been innovatively adopted together with the hydraulic system and electrical system to achieve automatic buffering point adjustment,which realizes the stable transition from punching process load to buffering load of the hydraulic press.Meanwhile,the hydraulic energy accumulated in the main cylinder and the elastic deformation of the frame can be controlled and released rapidly by adopting the rapid pressure relief device,so as to eliminate the sudden overshoot phenomenon of the slider which effectively reduces the impact and vibration caused by the punching and cutting process of the hydraulic press.
