In a method for thickening a plastically deformable hollow body wall of a hollow body, with effective radial support of the unthickened hollow body wall on an outer supporting face of an outer mold and with effective radial support of the hollow body wall on an inner supporting face of an inner supporting body, the hollow body is acted on by a compressive force by two application members at application points by moving the application members towards one another in the axial direction with a compressing movement. The application points on the hollow body are distanced from one another in the axial direction. An expansion space of the outer mold is arranged between the application points. Due to the compressing movement of the application members, material of the hollow body wall between the application points is plasticised in the region of the expansion space of the outer mold, and plasticised material of the hollow body wall flows into the expansion space of the outer mold, thus thickening the hollow body wall.

Provided is a forging method capable of preventing a vibration state from being disturbed during forming. The present invention relates to a forging method in which, when a forging material W1 in a forming hole 12 of a die body 11 is plastically worked by driving a punch 2 into a forming hole 12 of the die body, ultrasonic vibrations are applied to the die body 11. The contact state of the forging material W1 with respect to a forming hole inner peripheral surface during the plastic working of the forging material W1 is classified into an insufficient contact state, a sufficient contact state, and a full contact state in order from the forming start time. An application of ultrasonic vibrations is started after shifting from the insufficient contact state to the sufficient contact state.

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.

A press forming system includes a press working unit, a material supply device, a detection device, and a control device. The press working unit includes a slide that moves in accordance with an operation pattern in which the slide passes through an advance position where press forming is formed from a withdrawal position, and returns to the withdrawal position. The material supply device starts a supply operation at a synchronous timing before the slide returns from the advance position to the withdrawal position. The control device performs a control for stopping the slide before the slide reaches the withdrawal position from the advance position in a case where the suppliable state of the forming material is not detected within a predetermined determination period by the detection device.
