D53—Ⅱ型液压专用多刀机床是一种加工管件的机床,适用于成批或大批量加工水暖管件的螺纹,以及圆盘、环形零件的机加工。由于被加工的零件主要依靠螺纹定位,所以夹具采用涨紧形式(如图1所示)。将工件旋人心轴的55°圆锥管螺纹的心轴上,按动开关,油缸带动心杆将心轴涨紧。工件加工完毕,油缸卸油,心杆回原位,增速机构将工件自动卸下, D53-Ⅱ type hydraulic multi-knife machine tool is a machine tool pipe processing, suitable for batch or batch processing of plumbing pipe thread, as well as the disc, ring parts machining. As the parts to be machined mainly depend on the thread positioning, the clamps are in the form of tensioning (as shown in FIG. 1). The workpiece spiral mandrel 55 ° taper pipe thread on the mandrel, press the switch, the cylinder rod drive the mandrel tension tight. Workpiece processing is completed, unloading oil tank, the rod back to the original position, the body will automatically increase the speed of unloading,
