Abstract

PURPOSE:To correctly straighten a pipe material without causing a local dent, by making plural trumpet-shaped hollow die-rolls, being mounted on a rotary frme-body and having rotary axial-lines slanted against the advancing direction of the material, replaceable in accordance with the pipe material diameter. CONSTITUTION:A pipe material is inserted into a rotating rotary frame-body 20 through a guide rolls 2. The inserted pipe material is advabced zigzag according to the attached angles of dies 40, and is straightened uniformly, while being given bending moment by bringing it into linear contact with the inner surface of a hollow hole of a die-roll 43 to receive the actions of revolution and rotation of the dies 40. The material is given propelling force by the slant of rotating axis of the roll 43 to reach a crushing part 50, and is straightened more forcibly. The whole surface linear contact is made possible without loading any unreasonable force on the material by replacing the roll 43 with a new one through a die detaching hole 21a when the outer dia. of the pipe material is changed. Further, the bending quantity is adjusted by switching operation while rotating the body 20, because each die is movable perpendicularly to the advancing direction of the material; the part 50 is also made to be replaceable and movable.
