Abstract

PURPOSE:To manufacture the ring body excellent in the shape and dimensional accuracy with good durability of a mandrel by executing the cold rolling of a work with the driving of mandrel by the rotation of a support roller and a driving forming roller, in case of forming the ring body of the inner race, etc., of a bearing. CONSTITUTION:The forming roller 4 having a regulating face 4b at the upper and lower parts and a ring body forming part 4a is fitted to the movable frame 3 reciprocated in an arrow mark (a) direction by a piston ring 2 and made movable independently by a motor 19. The fixed frame 12 fitting the support roller 13 independently rotated by a motor 27 is also arranged and the mandrel 5 having a ring body forming part 5a is set in the middle of the both. The work 14 of the blank for forming the ring body is arranged between the forming roller 4 and mandrel 5 and the work 14 is subjected to cold rolling in a ring body by the both ring body forming parts 4a, 5a of the forming roller 4 and mandrel 5 with the rotations of both rollers 4, 13. In this case the ring body of high roundness and high accuracy is formed by cold rolling from the work 14 by controlling the number of revolutions of the support roller 13 corresponding to those of the forming roller 4 based on the variation in the diameter of the ring body by the deformation of the work 14.
