Japanese Patent JP2017177124
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing device for a wheel rim for an automobile in which a guide roll needs not to be replaced even if a shape (a shape of an outer peripheral surface in particular) of a rim work to be subjected to roll molding varies.SOLUTION: The manufacturing device comprises: a motor shaft 22 on which is mounted a bottom roll B; a motor that rotationally drives the motor shaft 22; a motor shaft 42 on which is mounted a top roll T; a motor that rotationally drives the motor shaft 42; a motor 31 which adjusts an interval between the motor shaft 22 and the motor shaft 42; a rotation shaft 53 on which is mounted a guide roll G; and a pressing mechanism. The pressing mechanism comprises: a base body 51; a moving body 52 that is supported to be movable relative to the base body 51 and supports the rotating shaft 53; and cylinder mechanisms 51a and 52 that adjust a position of the moving body 52 relative to the base body 51 and can move the guide roll G between a retreating position and a pressing position, which further, comprises a servo mechanism-type motor that adjusts a position in a shaft line direction of the base body 51.SELECTED DRAWING: Figure 2
