Abstract
PURPOSE:To simplify the rolling mechanism and its control, by driving the three rolling rolls which are provided with conical outer surfaces and mutually parallel axes of rotation and are supported touchably and detachably freely and mutually with a cylindrical backup roll. CONSTITUTION:A bar type material 10 is supported freely rotatably around its axis 10a and movably in its axial direction. Three rolling rolls 11, 12, 13 are arranged along the outer surface of the material 10 at intervals; the axes 11a, 12a, 13a parallel to the axis 10a of the material 10 are supported freely rotatably; besides, the rolling rolls 11, 12, 13 are supported freely touchably and detachably from the material 10. Conical surfaces 11b, 12b, 13b are respectively formed in each of outer surfaces of rolling rolls 11, 12, 13 and the large diameter side of conical surface 11b, 12b, 13b is placed on the front side of the advancing direction of the material 10; a cylindrical backup roll 14 wholly surrounding outer surfaces of rolling rolls 11, 12, 13 is installed freely touchably and detachably from rolling rolls 11, 12, 13; this backup roll 14 is connected to a hydraulic cylinder 15. The backup roll 14 is driven to rotate, and the rolling rolls 11, 12, 13 thereby roll the material 10, while the hydraulic cylinder 15 adjusts the position of the backup roll 14; hereby, a desired taper part is formed in the material 10.
