IDLE STRAIGHTENING APPARATUS FOR REGULATING ANGLE OF STEEL

摘要

One embodiment of the present invention provides an idle angle corrector includes: a supporting frame having a moving space part in which C-shaped section steel moves, wherein the C-shaped section steel has a web and a first and second flanges being respectively formed at both sides thereof; an upper roller part being coupled to the upper side of the supporting frame and pressurizing the upper side of the web; a lower roller part being coupled to the lower side of the supporting frame and pressurizing the lower side of the web; a first side roller part being coupled to the supporting frame and pressurizing the side of the first flange; and a second side roller part being coupled to the supporting frame and pressurizing the side of the second flange, wherein the upper roller part, the lower roller part, the first side roller part, and the second side roller part corrects the angle of the C-shaped section steel with being rotated by the transferring force of the C-shaped section steel ejected from a two-step roller, and the upper roller part includes: an upper correction roll having upper bearing mounting grooves at both sides thereof and pressurizing the upper side of the web; upper bearing being inserted into the upper bearing mounting grooves; an upper rotary shaft being inserted into the upper bearings with penetration and supporting the upper correction roll; and upper fixing parts being coupled to the supporting frame and supporting both ends of the upper rotary shaft.
