Abstract
PURPOSE: To make possible the continuous formation of the bend pipe like as elbow, etc., to improve the working efficiency, to save the labor, and to reduce the cost, by employing the bend pipe former constituted of the bending roll die, the caterpiller type pusher die, etc., at forming the bend pipe.
CONSTITUTION: The pipe P to be worked is conveyed by the roller conveyer 1 until the first half of the pipe 1 is laid on the guide parts 3; the forming groove 5a of the individual segment die of the caterpiller type pusher die 4 contacts with the upper half of the pipe P, the conveying projection 5b contacts with the rear end Po of the pipe P, and the pipe P is fed into the bending roll die 2. The pipe P is bent being pushed by the forming groove 5a of the segment die 5 and the forming groove 2a of the bending roll die 2; hereby, the bend pipe P' is obtained. The peripheral speed of the roll die 2 is made faster than the traveling speed of the pusher die 4 on purpose to tense the internal surface of the pipe P; and the reverse is also possible. According to this method, the bend pipe like as elbow, etc., can be continuously cold formed, the efficiency is improved, the labor is saved, and the cost is reduced.
