摘要： PURPOSE:To obtain a titled device intended to improve the efficiency of an elongation work, by installing a rotary housing in the inside of a supporting outer cylinder of a main frame, and disposing a clamping mechanism to the tip of the housing to automatically clamp or unclamp a mandrel bar. CONSTITUTION:A rotary housing 3 is installed in the inside of a supporting outer cylinder 2 provided to the front part of a movable main frame 1, and a catching head 5 equipped with a wedge guide 6 is fitted to the tip of the housing 3. Said wedge guide 6 advances and retreats by the contraction and extension of a cylinder 12 through a bearing 8, and closes and opens a clamp claw 7 to clamp and unclamp a mandrel bar 15. In a state that the bar is clamped, the bar 15, the claw 7, the wedge 6, an inner ring 8 of the bearing 8, and the housing 3, etc. rotate in one body. When unclamped, the bar 15 is pushed out of a clamp space 16 to the outside of the housing 3 with the aid of a pusher bar 17 by actuating a cylinder 19.
