Pipe cutting-off machine and process of cut-off of tubular pieces from a pipe

摘要

The tube cutting machine has the tubes (33) fed sideways from a rack onto a pair of tapered support rollers (36) mounted on the machine bed. At one end of the bed is the cutting head (5) and this has a cutting tool mounted on a plain cylinder support that is rotated on bearings (9). The head also has a fluid powered piston actuator (6) to move clamps (7). The axial position of the head is measured by a sensor. The cut off section of the tube is held in a gripper unit (19). A second tool (13) is moved in radially to finish the edge of the tube. Movements of cutters are controlled by commands from a CNC controller (41).
