Abstract
An application position of a processing force directed radially outward is continuously changed in the circumferential direction of a cylindrical portion (25) while applying the processing force to a part of the cylindrical portion (25) of a hub main body (21) in the circumferential direction. An application position of a processing force directed radially inward is continuously changed in the circumferential direction of a staking portion intermediary body (41) while applying the processing force to a part of the staking portion intermediary body (41) in the circumferential direction.
Claims4
A staking device comprising:
- a reference axis;
- a holder that supports a workpiece along the reference axis;
- a pressing die that has a center axis and a processing surface portion, the pressing die being arranged such that the center axis of the pressing die is inclined with respect to the reference axis, the processing surface portion of the pressing die having a first processing surface portion and a second processing surface portion, the second processing surface portion being located radially outward with respect to the first processing surface portion;
- a first mechanism that has a first motor to execute a relative rotational movement between the workpiece and the pressing die while the center axis of the pressing die is inclined with respect to the reference axis;
- and
- a second mechanism that has a second motor, a guide rail and a guide block to change an inclination angle of the center axis of the pressing die with respect to the reference axis, the second motor being different from the first motor.
