Abstract

PURPOSE: To device to draw a pipe efficiently even if it is very long by providing the first tapered body in a hollow piston rod, the second tapered body in the first one, and a pipe-drawing shaft penetrating through the hollow piston rod respectively.
CONSTITUTION: A hollow piston rod 9' is penetrated through a hollow cylinder 5' not to be turned, and a pipe-drawing shaft 3' is penetrated through the rod 9'. To the pipe-drawing shaft 3', a taper jig 30 to clamp the pipe-drawing shaft is fitted. The tapered jig 30 is composed of a collar 21 fitted to the end of the cylinder 5' with a thrust bearing 22 between, a frame 29 equipped at the end of the rod 9', a pair of tapered bodies 25 and 26 equipped inside the frame 29, and a pushing spring 27, while around the collar 21, a spiral groove 28 is provided to be fitted to a guide pin 23 projected on the inner wall of the rod 9'. This construction serves to draw a pipe efficiently even if it is very long.
