A C-frame press having a press frame, a first ram device, an opposed second ram device, and a drive device for moving at least one of the ram devices in a pressing direction. The press frame has first and second bending bars connected to each other by a tension column and a pressure column which together define a frame plane extending parallel to the pressing direction. The tension column is connected to each of the first and second bending bars by a bearing which is torque-free about an axis which extends perpendicularly to the frame plane. The first and second ram devices are each supported on the press frame by a bearing which is torque-free about an axis which extends perpendicularly to the frame plane. At least the at least one movable ram device is guided in a linear guide which extends parallel to the pressing direction.

A frame for a hydraulic apparatus includes at least two supporting pillars parallel to each other, a supporting assembly mounted on the at least two supporting pillars, and a link mechanism mounted on the supporting assembly and coupling the core plate to the adjustable die plate. The supporting assembly includes a fixed die plate, an adjustable die plate slidably, and a core plate. The fixed die plate includes a periphery sidewall and a surface perpendicular to the periphery sidewall, the fixed die plate defines a ring-shaped indentation in the surface and extending along a circumferential direction of the fixed die plate, the fixed die plate further defines at least two first through openings interconnected with the ring-shaped indentation and cut through the periphery sidewall.
