Abstract: Provided is construction which is able to downsize an orbital forging device comprising a spherical seat with shaft that swings and rotates with a molding die. The end section on the other side in the axial direction of the swinging shaft 13 is supported with respect to the driving mechanism 17 in a state where the movement toward one side in the axial direction (lower side) is prevented, and a member for preventing the swinging shaft 13 from moving toward the one side in the axial direction with respect to the frame 10 is not assembled in a section which is located between the convex spherical seat 14 and the driving mechanism 17 in the axial direction of the swinging shaft 13.

Abstract: Provided are an oil receiver (20) having an annular recess portion (52) which faces an entire circumference of an outer circumferential edge of a concave spherical portion (36), and a guide member (21) which guides lubricating oil, which has flowed out from a spherical engagement portion between a convex spherical portion (24) and a concave spherical portion (36), toward an annular recess portion (52).

Abstract: In a preparation step, a frame (10), a concave spherical seat (15), a convex spherical seat (13), a rotation body (16), a rotating shaft (12), and a work holder (17) are assembled, a laser head (33) is attached to the convex spherical seat (13), and a light receiving unit (38) is attached to the work holder (17). In a rotation body centering step, an irradiation position of a laser beam (LB) with respect to a laser irradiation surface (41) is changed by rotating the rotation body (16) while allowing the laser irradiation surface (41) to be irradiated with the laser beam (LB) emitted from the laser head (33) and a trajectory of the irradiation position is checked.

Abstract: The inspection device of the swing forging apparatus includes an inspection tool and a laser irradiation surface. When inspecting the swing forging apparatus, the inspection tool is supported to the head to which the processing roll is not supported, with a substantially same condition as the processing roll, and the inspection tool has a function of emitting a laser beam onto a central axis of the inspection tool. When inspecting the swing forging apparatus, the laser irradiation surface is arranged so that a relative position of the laser irradiation surface to the head in an axial direction of the head can be changed and the laser beam can be irradiated to the laser irradiation surface.
