Abstract
PURPOSE:To prevent a pipe material from the generation of flaws caused by bringing the material into contact with each other, by providing a continuous drawing apparatus of a pipe material constituted of a drum to coil the material around it, a die-box moving synchronously to the rotation of the drum, and a snubbing roll with grooves to retain the coiled material. CONSTITUTION:A drawn pipe material 2 is fixed at its tip by a gripping part 28 and is coiled around a rotating drum 4 from its underside. In this case, a die box 18 for drawing the pipe material 2 is moved by an hydraulic cylinder 14, of which moving action is made to synchronize the moving action of a driving mechanism 12 used for rotating the drum 4, in order to coil the material 2 spirally and regularly around the drum 4 with the prescribed pitches. When the pipe material 2 reaches the upper limit of the drum 4, the drum 4 is decelerated and, at the same time, the die-box 18 is stopped to release the material 2 from the gripping part 28, after the snubbing roll 24 is pressed to the pipe material 2 in order to press the material 2 against the drum 4. Thus the flaws, caused by bringing the pipe material into contact with each other, are prevented.
