Abstract
PURPOSE: To increase accuracy of a product in the premolding and rolling work, by supporting an opposite side to the eccentric direction of a lower rotary supporting mold, rotated in an eccentric position at a premolding roller side and finish molding roller side, with a retaining roller.
CONSTITUTION: When a peripheral wall part 4 of a cup-shaped base material 1 is performed premolding work, the peripheal surface of a lower rotary supporting mold 11 is formed in a smaller outside diameter than an inside diameter of the peripheral wall part 4 as an internal premolding roll surface 11a, further the mold is rotatively driven at the eccentric position in the side of a premolding roller 12 for the cup-shaped base material 1, then the roll surface 11a is attachably provided to internal peripheral surfaces of the peripheral wall part 4. And a side face 11b of the lower rotary supporting mold 11, at an opposite side to the eccentric direction of the mold, that is, at the opposite side to the premolding roller 12, is supported by a rotatable retaining roller 14 axially mounted to a fixed frame 13. Further rolling work is also performed in a similar manner, and deflection deformation of the lower rotary supporting mold can be prevented.
