There is provided a press device which causes a slide to advance and retreat to forge a forming object by using a die heated to a predetermined temperature. The press device includes a determination unit that determines whether or not a press operation enters a stable forging period during which a mechanical load acting on the slide in a press direction is stable, and a controller that adjusts a force acting on the forming object from the die to deform the forming object, based on a predetermined measurement value, when the determination unit determines that the press operation enters the stable forging period.

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.

A forging and pressing production systems enables at least one material to be formed by hot melt and forging and pressing by itself without human operation, thereby completing the mass production of the material. Operating factors such as the pressure, temperature and mold required for formation are taken into account, and the identification requirements for the material are reduced, thereby realizing large-scale production.

A method for monitoring and changing the position of at least one component, more particularly a running bar, slidingly guided within a press frame between abutments of the press frame is disclosed. A central alignment of the component within the press frame is continuously measured and the alignment of the component within the press frame is corrected as a function of the acquired measurement result by preferably automatically adjustable guide elements of the sliding guides of the press. The central alignment of the slidingly guided component within the press frame is measured by the sensing of the location of at least one, preferably two, reference points of the slidingly guided component preferably in a plane extending perpendicularly to the longitudinal center axis of the press. A press having automatically adjustable guide elements and means for controlling the guide elements as a function of the measured position of the component.

There is provided a press device including a reference operation setting unit that sets a reference transport motion of a transport device which corresponds to a predetermined reference press motion of the slide, a timing setting unit that sets a synchronous timing of the reference transport motion for the reference press motion, a press operation setting unit that sets a press motion of an actual operation by extending a time of a part of the reference press motion, and a transport operation setting unit that sets a transport motion of the actual operation which corresponds to the press motion by matching synchronous timings with each other between the press motion and the reference transport motion for the reference press motion, and by setting an operation pattern from the synchronous timing to be the same as that of the reference transport motion.

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.

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.
