<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for straightening the bend of a wide flange beam, with which straightening and changing operations are performable simply when straightening the wide flange beam which is different in the dimensions of a cross section. <P>SOLUTION: The apparatus includes: inner rolling roll supporting parts 19, 20 for supporting inner rolling rolls 14, 15 freely rotatably; an inner rolling roll housing 12 in which these inner rolling roll supporting parts support the rolls by taking rotating pins 19a, 20a as the center of rotation so as to be freely swingable within a plane crossing orthogonally to the conveying direction of the wide flange beam 1 and which is provided with the inner rolling rolls, whose rotating shaft is extended vertically, so as to be away from and close to the inner surface of the left flange 1b1; inner rolling roll pressing-down means 16, 17 for making the inner rolling rolls press down the inner surface of the left flange; an outer rolling roll 23 for pressing down the outer surface of the left flange; and an outer rolling roll housing 13 for supporting the outer rolling roll so that the rotating shaft is extended vertically. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
