Claims

[Scope of utility model registration request]

A rotating swing shaft is interlocked with an inner eccentric sleeve inserted into an outer eccentric sleeve that is rotationally driven, and a conical mold with a blunt apex angle is attached to the center of the tip of the rotating swing shaft with an inclined axis. In a rotary oscillating forging machine, the inner eccentric sleeve is rotatably attached to the outer eccentric sleeve. A locking piece is provided for inserting the inner eccentric sleeve into the outer eccentric sleeve, and a locking control mechanism is provided for controlling the locking and release of the locking piece. A tilt angle adjustment mechanism that adjusts the tilt angle of the rotational swing shaft, and a control mechanism that controls these locking control mechanisms and tilt angle adjustment mechanisms are provided, and the locking control mechanism and tilt angle adjustment mechanism are arranged on the outside. An automatic inclination angle adjustment device for a rotary oscillating shaft of a rotary oscillating forging machine, characterized in that it is provided so as to be able to move toward and away from an eccentric sleeve and an inner eccentric sleeve.
