Benefits of technology

[0007]The goal of the present invention is to create a roll arrangement, especially a roll arrangement of the work rolls of a rolling stand, by means of which the rolls can be easily adjusted in the axial direction and the disadvantages of the prior art avoided.
[0009]It is advisable for the stationary frame to be connected to the rolling stand. The frame connected to the rolling stand represents a compact and low-cost solution, because the forces which occur during the rolling process and during the axial shift of the rolls are also absorbed by the rolling stand.

Problems solved by technology

These roll arrangements with axial shifting devices according to the prior art are of relatively complicated design.

Embodiment Construction

[0018]In all the figures, the same technical elements are designated by the same reference numbers.

[0019]FIG. 1 shows a top view of a first exemplary embodiment of a roll arrangement 1 with two axially adjustable rolls 2, 3, which can be pushed in the axial direction by a shifting unit or adjusting means 4 on the drive side of the rolling stand. The forces which thus arise must be absorbed. This is done by a frame 8 or frame structure in which the shifting unit or adjusting means 4 are mounted. To this end, the adjusting means 4 comprise two hydraulic cylinders 5, 6, which are mounted in a block 7, which is held in turn in the frame 8. The frame preferably consists of a welded frame, which is assembled from welded-together frame elements and which holds the adjusting means 4. These are preferably moved in the rolling direction and / or in the direction opposite the rolling direction by the bearing holders 15, 15a, 18, 18a and by the cylinders 19, 20 seated in the stationary frame part...

Abstract

The invention pertains to a roll arrangement (1, 101, 201), especially a roll arrangement of the work rolls (2, 3, 102, 103, 202, 203) of a rolling stand, which can be shifted in the axial direction by adjusting means (4, 104, 204), where the adjusting means (4, 104, 204) comprise at least one hydraulic cylinder (5, 6, 105, 106, 205), which controls the axial shiftability of the rolls, where the hydraulic cylinder is arranged in a frame, which is stationary or adjustable.

Description

TECHNICAL AREA[0001]The invention pertains to a roll arrangement such as a roll arrangement of work rolls of a rolling stand.PRIOR ART[0002]Rolling stands with work roll arrangements for the processing of stock to be rolled, such as the processing of flat metal or steel strip, are known. Devices for shifting the rolls to improve the quality of the strip are also known for these roll arrangements.[0003]For example, reference can be made to the publications EP 0 154 896 B1, EP 0 118 812 B1, and DE 25 22 213 A1, which disclose roll arrangements with roll guide means, which make it possible to adjust the rolls in a plane perpendicular to the axis of the rolls.[0004]DE 35 21 180 A1, furthermore, discloses a roll arrangement with a device for adjusting the rolls in the axial direction, wherein the rolls are supported in sliding chocks and can be adjusted by means of hydraulic cylinders, which are braced against the roll stand and the bearing support.[0005]Axial adjustable roll arrangement...
