我厂有一台B558插床是59年早期仿苏产品,由于原设计的缺欠,存在滑枕停不住、切削力不足及液压系统漏油过于严重等现象。产生这些现象较重要的两个原因是: 第一、原机床66—24型止回阀性能太差,当调整压力高了,切削力不足;如果调整压力低了,平衡不了滑枕重量要掉刀。第二、原机床底部兼作油箱,容积小,工作时温度过高,造成液压系统漏油严重。针对上述不足,从以下两方面进行改装: I plant a B558 slotting machine is 59 years ago Imitation Su products, due to the lack of original design, the existence of ram can not stop, lack of cutting force and the hydraulic system is too serious oil spills and so on. Two of the more important causes of these phenomena are: First, the original machine 66-24 check valve performance is poor, when the adjustment pressure is high, the cutting force is not enough; if the adjustment pressure is low, the balance can not balance the ram to fall Knife. Second, the former at the bottom of the machine as a fuel tank at the bottom, small volume, high temperature during work, resulting in serious oil spills hydraulic system. In response to the above shortcomings, from the following two aspects of modification:
