Description

    TECHNICAL AREA
  • The invention pertains to a roll arrangement such as a roll arrangement of work rolls of a rolling stand.
    • PRIOR ART
  • 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.
  • 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.
  • 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.
  • Axial adjustable roll arrangements of this type are used to influence the roll gap contour by way of the grind of the work rolls and intermediate rolls.
  • These roll arrangements with axial shifting devices according to the prior art are of relatively complicated design.
    • DESCRIPTION OF THE INVENTION, GOAL, SOLUTION, ADVANTAGES
  • 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.
  • According to the invention, the goal is achieved with a roll arrangement, especially a roll arrangement of the work rolls of a rolling stand, which rolls can be shifted in the axial direction by adjusting means, wherein the adjusting means comprise at least one hydraulic cylinder, which controls the axial shiftability of the rolls, characterized in that the hydraulic cylinders are arranged in a frame, which is either stationary or adjustable. The hydraulic cylinder is used to shift the roll in the axial direction. The forces which develop during this process must be absorbed, which is realized advantageously by a frame structure, in which the adjusting means, such as a shifting unit, are mounted. Actuation proceeds advantageously by way of bearing holders and by way of cylinders mounted in the crosspiece which connects the two side pieces of the frame.
  • 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.
  • It is also advantageous for the frame to consist of welded-together frame elements. In the case of a welded frame, the frame consists advantageously of three essential parts, which are welded to each other, wherein two side pieces are parallel to each other and are connected by a crosspiece.
  • According to another exemplary embodiment of the invention, it is advantageous for the adjustable frame to be connected to the bearing holders of means for shifting or adjusting the rolls. To this end, especially for HS (horizontal stabilization) adjustment, the bearing holders can be pushed in the rolling direction or in the opposite, direction. The adjustable part of the frame also executes this movement, so that the axial force from the rolling process and/or the necessary shifting force is directed preferably toward the center of the roll and preferably perpendicularly to the rolling direction. In the case of HS adjustment, the bearing holders are advantageously pushed in the rolling direction or in the opposite direction. The adjustable part of the frame also executes this movement, so that the axial force of the rolling process or the necessary shifting force is always essentially centered with respect to the roll and perpendicular to the rolling direction.
  • It is also advantageous for the means for shifting or adjusting the rolls to be used for horizontal stabilization adjustment (HS adjustment). It is advantageous for the shifting or adjusting unit to be shifted by the HS adjustment, that is, by the shift which occurs in the rolling direction or in the opposite direction.
  • Advantageous elaborations are described in the subclaims.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The invention is explained in greater detail below on the basis of the drawings:
  • FIG. 1 shows a diagram of an inventive device according to a first exemplary embodiment;
  • FIG. 2 shows a diagram of an inventive device according to a second exemplary embodiment; and
  • FIG. 3 shows a diagram of an inventive device according to a third exemplary embodiment.
    •  PREFERRED EMBODIMENTS OF THE INVENTION
  • In all the figures, the same technical elements are designated by the same reference numbers.
  • 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, 15 a, 18, 18 a and by the cylinders 19, 20 seated in the stationary frame part. The hydraulic cylinders 5, 6 act on a block 9, which holds the work roll locking device.
  • On both the operating side and the drive side 10, the rolls 2, 3 are supported in a sliding manner, so that they are held even when shifted by the hydraulic cylinders 5, 6.
  • Means 11, 12, 13, and 14, furthermore, are also provided, by means of which the bearing holders 15, 16, 17, 18 of the rolls can also be adjusted perpendicularly to and in the direction of the axis A by a pivoting movement.
  • It is advantageous for this embodiment to be provided with a stationary frame, because the frame 8 can be produced compactly and also at low cost in comparison to a frame which must be mounted on a surrounding foundation, because the forces which occur in the rolling process and during the axial shifting of the rolls will again be absorbed by the rolling stand.
  • The frame 8, as explained above, is designed as a welded structure. This offers the advantage that it can be built in modular fashion out of frame elements. It can consist advantageously of three frame elements, wherein the two side pieces of the frame 8 are shown in FIG. 1, with a connecting crosspiece 8 a, which advantageously connects the two side pieces.
  • FIG. 2 shows a second advantageous exemplary embodiment of a roll arrangement 101 with axially adjustable rolls 102, 103, which can be pushed in the axial direction by adjusting means 104 on the drive side. To this end the adjusting means 104 comprise two hydraulic cylinders 105, 106, which are mounted in a block 107, which is held in turn in a frame 108.
  • The frame 108 is advantageously designed as an integral part of the bearing holders 118, 115. Here, too, the means 111, 114 are used to pivot the bearing holders. The frame 108 holds the adjusting means 104. The hydraulic cylinders 105, 106 act on a block 109, which holds the work roll locking device. The means 111, 114 are also used for the HS adjustment.
  • On the operating side 110 of the rolling stand of the two rolls 102, 103, the rolls are mounted in a sliding manner, so that, when the rolls 102, 103 are shifted by the actuation of the hydraulic cylinders 104, 106, they are still supported reliably.
  • Means 111, 112, 113, and 114, furthermore, are again provided, by means of which the bearing holders 115, 116, 117, 118 of the rolls 102, 103 can also be adjusted perpendicularly to and in the direction of the axis by a pivoting movement.
  • Blocking cylinders 120, 121, which can be extended, are used to lock the rolls in position.
  • Although the inventive device according to FIG. 2 requires longer cylinder blocks for the shifting blocks of the means 111, 112, 113, and 114, it is nevertheless very compact in design in the direction perpendicular to the roll axes.
  • FIG. 3 shows a third advantageous exemplary embodiment of a roll arrangement 201 with axially adjustable rolls 202, 203, which can be pushed in the axial direction by adjusting means 204 on the drive side of the rolling stand. To this end, the adjusting means 204 comprise a hydraulic cylinder 205 with a piston rod, which can be rotated by a pivot drive for the purpose of pushing the rolls forward. It is advantageous for the rolls to be locked in position by the rotational movement of the piston rod. This arrangement is again mounted in a frame 208.
  • The frame 208 is advantageously designed as an integral part of the bearing holders 218, 215. The means 211, 214 serve to adjust the rolls 202, 203. It is advantageous for the frame 208 to hold the adjusting means 204.
  • On both the operating side and the drive side 210 of the two rolls 202, 203, the rolls are mounted in a sliding manner, so that, when the rolls 202, 203 are shifted as a result of the actuation of the hydraulic cylinder 205, they are still supported reliably.
  • Means 211, 212, 213, and 214, furthermore, are also provided, which make it possible to adjust the bearing holders 215, 216, 217, 218 of the rolls 202, 203 perpendicular to and in the direction of the axis by a pivoting movement.
  • The inventive device of FIG. 3 is also highly compact in design.
  • In the same way that a roll is adjustable in the exemplary embodiments described above, it is possible to provide hydraulic cylinders 5, 6, 105, 106, 205 for each roll, so that the two rolls 2, 3, 102, 103, 202, 203 can be shifted independently of each other.
