Device and method for installing and adjusting sliding block of multipoint crank press

The present invention discloses a device and method for installing and adjusting a sliding block of a multipoint crank press. The device comprises a crank, a connecting rod with an end provided with a U-shaped notch, a sliding block and an eccentric pin shaft micro-adjustment mechanism. The eccentric pin shaft micro-adjustment mechanism is installed at the joint between the connecting rod and the sliding block. The crank, the connecting rod and the sliding block of the multipoint press are normally machined and installed through a classical process, so that the sliding block of the multipoint press runs to a bottom dead center. A gap among mechanisms is eliminated through the loading by a hydraulic loader. The position of one set of crank, connecting rod and sliding block mechanism is taken as a reference, and then the eccentric positions and directions of the eccentric pin shafts at other adjustment positions are finely adjusted, thus realizing high-precision assembly and operation of the multipoint press.

A radial forge is provided with variable radial displacement. The forge includes upper and lower frames having upper and lower double acting hydraulically driven rams. The forge also includes a horizontal master gear mounted on a circular thrust bearing to provide rotational freedom. One or more radial hydraulically drive rams are mounted to the master gear. Accordingly, the master gear serves as a gantry for positioning the radial rams. A billet may be centrally located between the inwardly directed radial rams and may be supported by the lower ram. The upper ram is aligned with the lower ram so that actuating the upper ram and/or lower ram compresses the billet between them and forces the billet to flow into and fill radial dies removably affixed to the radial rams.

PRESS DEVICE, CONTROL METHOD FOR PRESS DEVICE, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONTROL PROGRAM
20220203492 · 2022-06-30 ·

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.

Press forming system

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.
