CRANK PRESS
A crank press with an adjustable stroke comprises a press frame having a frame slideways therewithin with a slider reciprocatively movable therealong and supported by a pneumatic cylinder. In order to significantly increase a working force, a length of the working stroke and efficiency, the crank press further comprises: at least two mutually synchronized crank drives configured for reciprocatively moving the slider along the frame slideways, a lever-crosspiece mechanism having at least one pair of threaded guide stanchions secured within the frame bed, a crosspiece slidably mounted on the guide stanchions atop the slider, at least two two-arm levers hingedly connected to the slider supportadly on the crosspiece, at least one pair of crosspiece stop nuts engaged with threads of the guide stanchions and configured for arresting the cross-piece at the moment of applying a force to the slider by the lever and a switching arrangement for slider reversal with regulation of its stroke.

Shaping device, in particular a spindle press, and method for shaping workpieces
A forming device, (e.g., a spindle press), can include a processing head, having a processing tool that is guided along a movement axis for the forming processing of a workpiece, and a processing region, located opposite the processing head, a processing station configured for the forming processing of the workpiece, and a rotary table having an axis of rotation parallel to the direction of movement and workpiece receptacles that are arranged, with respect to the axis of rotation, in an offset manner with respect to one another in the circumferential direction. The rotary table is configured such that each of the workpiece receptacles is transferable into at least one first working position located within the processing region and into at least one, second working position at least partially laterally outside a cross-sectional area of the processing head in axial projection with respect to the axis of movement.

Peripheral Combination Hydraulic Press to Forge and Method of Manufacturing Thereof
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.
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.
Method and apparatus for producing forging by rotary forging
A cycle is repeated a plurality of times, which includes a forging process for placing a material to be forged in a lower die and pressing the material to be forged in this state and then separating an upper die from the material to be forged; an elevation process for lifting the material to be forged by using an elevation device to separate the material to be forged from the lower die; a rotation process for rotating the material to be forged around its center by using a rotation device; and a lowering process for placing the material to be forged rotated by the elevation device in the lower die.
Forging heads and fixing devices with aligned through-holes and cavities
A forging head for additive manufacturing, comprising a base portion and a forging portion. The forging portion extends from the base portion for forging a cladding layer during formation of the cladding layer by additive manufacturing. The forging head further comprising a through hole which is formed through the base portion and the forging portion, for at least one of an energy bean and an additive material to pass through during formation of the cladding layer.
