Definitions
- the invention relates to a roller arrangement, in particular a roller arrangement of work rolls of a roll stand.
- DE 35 21 180 A1 discloses a roller assembly with a device for axially displacing the rollers, wherein the rollers store in slidably mounted chocks and with hydraulic cylinders, which are supported against the roll stand and the support of the bearing, are displaced.
- Such axially displaceable roller arrangements are used in order to be able to influence the roll gap contour via the grinding of the working and intermediate rolls.
- the object is achieved with a roller arrangement, such as in particular a roller arrangement of work rolls of a roll stand, which are axially displaceable by means of displacement means, wherein the displacement means comprise at least one hydraulic cylinder, which controls the axial displaceability of the rollers, characterized in that the hydraulic raulikzylinder in a frame are arranged, which is fixed in space or displaced.
- the hydraulic cylinder is used for the axial displacement of the roller.
- the occurring forces must be absorbed, which is advantageously realized by a frame construction, in which the displacement means, such as a displacement unit, are added.
- the actuation is advantageously carried out via the bearing receivers, as well as in the web, which connects the two frame legs, recorded cylinder.
- Roll stand is connected.
- the frame connected to the rolling stand represents a compact and cost-effective solution, since the in the rolling process and during the axial displacement of the rollers occurring forces are taken up again in the rolling stand.
- the frame consists of frame members welded together.
- the frame is advantageously made of three essential parts that are welded together, with two legs are parallel and connected via a web.
- the displaceable frame is connected to bearing receivers of means for displacing or adjusting the rollers.
- the bearing receivers can be displaced in or counter to the rolling direction.
- the displaceable part of the frame also carries out this movement so that the axial force from the rolling process and / or the necessary displacement force is preferably aligned centrally with respect to the roller and preferably perpendicular to the rolling direction.
- the bearing receivers are advantageously displaced in or counter to the rolling direction.
- the displaceable part of the frame also carries out this movement so that the axial force from the rolling process or the required displacement force is always essentially centered on the roll and perpendicular to the rolling direction.
- FIG. 1 shows an illustration of a device according to the invention according to a first embodiment
- FIG. 2 shows an illustration of a device according to the invention according to a second embodiment
- Fig. 3 is an illustration of a device according to the invention according to a third embodiment.
- FIG. 1 shows a top view of a first embodiment of a roller assembly 1 with two axially displaceable rollers 2,3, which can be moved by means of displacement unit or displacement means 4 on the drive side of the rolling mill in the axial direction.
- the occurring forces must be absorbed.
- the displacement means 4 has two hydraulic cylinders 5, 6, which are accommodated in a block 7, which in turn is held in a frame 8.
- the frame preferably consists of a welded frame, which is composed of frame elements and welded and receives the displacement means 4. These are preferably moved in and / or counter to the rolling direction by the bearing receivers 15, 15a, 18, 18a and the cylinders 19, 20 seated in the fixed frame part.
- the hydraulic cylinders 5, 6 act on a block 9, which receives the work roll lock.
- the rollers 2,3 are slidably received, so that they are still held even with a shift, the hydraulic cylinder 5,6.
- means 11, 12, 13 and 14 are provided by means of which the load carriers 15, 16, 17, 18 of the rollers can also be displaced perpendicular to the axial direction A and in the axial direction by a pivoting movement.
- This embodiment is advantageous with a space-fixed frame connected to the roll stand, because the frame 8 can be produced compactly and cost-effectively in comparison to a frame which has to be arranged on a surrounding foundation, since those in the rolling process and during the axial displacement of the rolls occurring forces are taken up again in the rolling stand.
- the frame 8 is, as stated above constructed as a welded construction. This has the advantage that it can be modularly constructed from frame elements. It may advantageously consist of three frame elements, wherein in Figure 1, the two legs of the frame 8 are shown with a connecting web 8a, which advantageously connects the legs.
- FIG. 2 shows a second advantageous embodiment of a roller assembly 101 with two axially displaceable rollers 102,103, which can be moved by means of displacement means 104 on the drive side in the axial direction.
- the displacement means 104 has two hydraulic cylinders 105, 106, which are received in a block 107, which in turn is held in a frame 108.
- the frame 108 is advantageously formed integrally with the bearing receivers 118, 115.
- the means 111, 114 serve to pivot the Lageraufillon.
- the frame 108 receives the displacement means 104.
- the hydraulic cylinders 105, 106 act on a block 109, which receives the work roll locking.
- the means 111 and 114 are also used for HS adjustment.
- the rollers are slidably received, so that the rollers 102,103 are held displaceable by the displacement due to the control of the hydraulic cylinders 105,106.
- means 111, 112, 113 and 114 are provided by means of which the bearing receivers 115, 116, 117, 118 of the rollers 102, 103 are also displaceable perpendicular to the axial direction and in the axial direction by a pivoting movement.
- the device according to the invention according to FIG. 2 requires longer cylinder blocks of the displacement blocks of the means 111, 112, 113 and 114, it is nevertheless very compact in the direction perpendicular to the roller axes.
- FIG. 3 shows a third advantageous embodiment of a Walzenan- order 201 with two axially displaceable rollers 202,203, which can be moved by means of displacement means 204 on the drive side of the roll stand in the axial direction.
- the displacement means 204 on a hydraulic cylinder 205, which has a rotatable by means of pivoting piston rod to achieve a propulsion of the rollers.
- the locking of the roller position is advantageously carried out via the rotational movement.
- This arrangement is in turn held in a frame 208.
- the frame 208 is advantageously formed integrally with the bearing receivers 218,215.
- the means 211, 214 serve to displace the rollers 202, 203.
- the frame 208 advantageously receives the displacement means 204.
- rollers 202,203 On the operating side and drive side 210 of the two rollers 202,203, the rollers are slidably received, so that the rollers 202,203 are held displaceable by the displacement due to the control of the hydraulic cylinder 205.
- means 211, 212, 213 and 214 are still provided by means of which the bearing receivers 215, 216, 171, 218 of the rollers 202, 203 are also displaceable perpendicularly to the axial direction and in the axial direction by a pivoting movement.
- the inventive device of Figure 3 is also very compact.
- a roller is shown as being displaceable, hydraulic cylinders 5, 6, 105, 106, 205 are provided per roller so that the two rollers 2, 3, 10, 10, 10, 20, 20, 203 can be displaced independently of one another.
