ABSTRACT:
The stand-supported bending device for the axially slidable rolls of a rolling mill comprises at least one bending cylinder whose piston acts on a mount of a slidable roll provided with an intermediate piece guided tilt-free in a supporting block covering one or more of the pistons. The intermediate piece is provided with a mount facing planar pressing surface. Since the opposing pressing surface is located on the mount, e.g. on laterally extending engaging lugs of the mount, symmetric to the transverse central plane of a radial bearing of the mount, the bending force acts continuously on this mount in this central plane whose lateral relative position the mount of the axially slidable rolls may take relative to the bending device. The tilt-free guiding which absorbs the tilting torque or moment of the intermediate piece can be improved by a mechanical or hydraulic synchronizing device. Then the pistons are no longer exposed to transverse forces due to the axial sliding of rolls and/or their mounts. All hydraulic connections are made rigidly.
