我厂Ｑ4 2 50 0型棒料剪断机是一种高效下料设备 ,工作时带剪刀的滑块在两Ｖ型导轨上上下滑动 ,Ｖ型导轨与滑块上的导轨的间隙靠偏心轴与轴套调整 ,如图 1所示。原导轨与滑块上的导轨槽的间隙调整好以后 ,靠螺母 2及螺母 4与机体 3的摩擦力来锁定偏心轴 ,以防松动。由于工作时 I plant Q4 2 50 0 bar cutting machine is an efficient cutting equipment, work with scissors in the slide on the two V-type rails slide up and down, V-shaped rails and slider on the guide rail gap by eccentric shaft and Sleeve adjustment, shown in Figure 1. After adjusting the gap between the guide rail and the guide rail groove on the slider, the eccentric shaft is locked by the friction force between the nut 2 and the nut 4 and the body 3 to prevent loosening.
