Claims

[Claims for Utility Model Registration] 1. Upper and lower parts that give a certain bend to the transported material 1.
A plurality of pairs of rolls are assembled in the horizontal direction, and the upper roll or lower roll of these paired rolls is movable in the vertical direction with respect to the lower roll or the upper roll,
In the roll straightening machine, which is disposed offset in the axial direction, a V-shaped groove for straightening materials such as square bars, rectangular bars, round bars, etc. is provided on the outer peripheral surface of the lower roll or the upper roll, and an angle material, etc. V-shaped convex portions for material straightening are provided in parallel in the axial direction, and the material is straightened in cooperation with the grooves or convex portions of the lower roll or upper roll on the outer peripheral surface of the upper roll or the lower roll. A roll straightening machine characterized by having a V-shaped groove and making an upper roll or a lower roll movable in the axial direction. 2 Up and down that gives a certain bend to the transported material 1
A plurality of paired rolls are assembled in the horizontal direction, and the upper roll or lower roll of the paired rolls is movable in the vertical direction with respect to the lower roll or the upper roll, and is arranged with a position shift in the axial direction. In the roller straightening machine, the outer peripheral surface of the lower roll or the upper roll is provided with a V-shaped groove for straightening materials such as square bars, rectangular bars, round bars, etc., and a V-shaped protrusion for straightening materials such as angle materials. A V-shaped member is provided in parallel in the axial direction, and is located at a position facing the grooves and convex portions of the lower roll or upper roll on the outer circumferential surface of the upper roll or lower roll, and cooperates with the grooves to straighten the material. A roll straightening machine comprising a first groove and a V-shaped second groove that cooperates with the convex portion to straighten the material.
