A forging machine includes a first tool carrier and a second tool carrier, a drive system for driving the first tool carrier in a working movement, a machine frame, wherein the machine frame is formed of a concrete prestressed with prestressing elements, wherein the machine frame comprises a frame base and a frame support connected to the frame base, wherein longitudinal prestressing elements are provided which extend parallel to the central axis (M) and each extend through the frame support, the frame base, and through the cross-member, wherein transverse prestressing elements are provided both in the frame base and in the cross-member, wherein the longitudinal prestressing elements and the transverse prestressing elements include prestressing anchors, and wherein the prestressing anchors are each arranged on an outer surface of the frame base or the cross-member.

A modular press suitable for use in the manufacture of EWC products may include a plurality of frame modules coupled together and aligned along a feed path axis. Each frame module may have a generally planar body supported on a corresponding pair of bases, an elongate aperture, an upper and a lower platform within the aperture, and a platen between the platforms. Optionally, the ends of the aperture may be curved. A first actuator system may be operable to move the platen from a raised position to an intermediate position, and a second actuator system may be operable to press the platen downwardly from the intermediate position onto a workpiece within the aperture. Some modular presses include conveyor rolls and a third actuator system to raise and lower the conveyor rolls. In some embodiments, the actuator systems may be pneumatic actuator systems. Corresponding methods and systems are also described herein.

Provided is a combined cold isostatic press and general press capable of simultaneously performing cold isostatic pressing using pressure of fluid and general pressing using mechanically applied pressure. The combined cold isostatic press and general press includes a main frame having a center penetration region, a pressure vessel supported by the penetration region of the main frame, the pressure vessel performing cold isostatic pressing using fluid injected therein, a top lid installed to be vertically slidable from or to an upper end of the pressure vessel by the fluid filled in the pressure vessel so as to function as piston, the top lid being configured to open or close the upper end of the pressure vessel, a lower lid configured to open or close a lower end of the pressure vessel and a press unit located between the top lid and the main frame to perform pressing using pressure applied by the top lid as the top lid slides from the pressure vessel. As such, enhanced productivity and reduction in fluid consumption and manufacturing costs may be accomplished.

The present disclosure provides an oil hydraulic press including a support frame, at least one main cylinder assembly and at least one fixed die table. The at least one main cylinder assembly and the at least one fixed die table are disposed in the support frame. A pressing mechanism is formed between the at least one main cylinder assembly and the at least one fixed die table. The support frame is in an annular or ring-like shape and is configured for fixing the at least one main cylinder assembly and the at least one fixed die table. The main cylinder assembly and the fixed die table can be fixed by the support frame, which forms a ring-like structure, can be operated in one, two or multiple sets in parallel, and all can realize pressing manufacture. The oil hydraulic press has less components, reduced material consumption and low manufacturing cost.

A radial press is provided having a main structure, a plurality of pressing jaws arranged around a pressing axis, and having a drive unit which acts on the pressing jaws. The drive unit is supported on the main structure and can move the pressing jaws radially in the direction of the pressing axis and away from the same, at least one fibrous structure is provided radially outside the pressing jaws, the fibrous structure enclosing the pressing jaws and extending in annularly closed form around the pressing axis in a plane which is substantially perpendicular to the pressing axis.

In an example, a cubic press is described having press bases with spacers disposed between adjacent press bases. Sets of two or more tie bars are also disposed between adjacent press bases. The tie bars are placed in a state of compression while the spacers are placed in a state of compression. During operation, the press bases may become displaced relative to one another such that additional tension is experienced by the tie bars while the amount of compression experienced by the spacer is reduced. The tie bars exhibit a relatively small cross-sectional area as compared to the cross-sectional area of the spacer.
