Abstract: A workpiece manipulator (1) for use with a radial forging press includes workpiece tongs (4). The workpiece tongs (4) are fastened to a manipulator frame (2) guided linearly on a manipulator track. The workpiece tongs (4) form a chuck with a fixed clamping axis (5) which extends in the forging axis or parallel to the forging axis. The workpiece can be manipulated with a linear translational movement. The manipulator frame (2) is rail-bound on wheels (12) during the translational movement.

Abstract: In order to widen the field of application of a stretcher-leveler having a minimum nominal width, at least one gripping head of the stretcher-leveler is connected to an adapter having clamping elements for clamping a plate to be stretched, the adapter having a nominal width that is smaller than the minimum nominal width of the stretcher-leveler, and a plate being stretched is connected to the gripping head via the adapter clamping elements and the adapter, before starting the stretching process.

Abstract: A hydraulic cylinder comprising a cylinder, a piston element movably guided in the cylinder in a working direction and comprising an active surface, and a first opening for feeding a fluid into a cylinder chamber by the active surface. A working pressure of the fluid acting on the active surface drives the piston element in the working direction. The active surface includes a first partial surface and at least one second partial surface, the cylinder chamber being divided into a first sub chamber with the first opening by the first active surface and a second partial surface with a second opening by the second partial surface, and the partial surfaces are hydraulically separated from each other at least in a selectable operating mode.
