Abstract:
PROBLEM TO BE SOLVED: To provide a rolling device capable of correcting undulation of a tooth trace.SOLUTION: Provided is a rolling device 1 for rolling-molding a rod-like raw material W by an infeed system, which comprises: a support part 20 for supporting the rod-like raw material W rotatable around the axis; and round dies 35 and 45 on the outer peripheries of which die teeth are formed and which are arranged so that the dice teeth contact with an outer peripheral surface of the rod-like raw material W supported by the support part 20. The die tooth comprises a molded die tooth T1 for creating a processing tooth T3 on the outer peripheral surface of the rod-like raw material W and a finished die tooth T2 for improving tooth surface accuracy of the processing tooth T3 by rotating while meshing with the processing tooth T3. The finished die tooth T2 is formed in such a shape that its tooth tip does not contact with the tooth bottom of the processing tooth T3.
