LONG-SIZE WORK-PIECE SUPPORT MECHANISM OF THE ROLL STRAIGHTENING MACHINE PROJECTION PORT SIDE

摘要

PROBLEM TO BE SOLVED: To provide a long-size work-piece support roll of the roll straightening machine projection port side capable of preventing the occurrence of scratch on the long-size work-piece surface.SOLUTION: A long-size work-piece support mechanism configured such that guide/support rolls 2, 4 are arranged in a row along a work-piece carrying line L on the roll straightening machine projection port side and, on the other hand, a long-size work-piece W is supported by the respective guide/support rolls 2, 4 and, at the same time, is carried and is projected to a straightening roll 10 of a roll straightening machine 1 is provided. At least one of the guide/support rolls 2, 4 is constituted with a split-type roll 5 provided with a pair of roll main bodies 51a, 51b which are rotatable around an axial center independently on each other. A lower part of one side lateral half part of a long-size work-piece outer circumferential surface is supported by an outer circumferential surface of roll main body 51a of one side and, at the same time, a lower part of an other side lateral half part of the long-size work-piece outer circumferential surface is supported by an outer circumferential surface of roll main body 51b of the other side.SELECTED DRAWING: Figure 2
