Definitions
- the invention relates to a rolling device with at least two rollers, which are each mounted by means of roll chocks in a rolling stand, wherein the rollers are provided with Axialverschiebeschn for axial displacement in a displacement direction with which the rollers are brought relative to the rolling mill in a desired position and held there and wherein the rollers are in operative connection with bending means, with which they can be subjected to a bending moment.
- a rolling device of this kind is known, for example, from WO 2005/011884 A1, in which two work rolls, which are located at a defined distance from one another, form the roll gap required for rolling, wherein the work rolls can be supported on support rolls or intermediate rolls.
- a rolling device formed in this way can therefore be equipped with four or six rollers, wherein the individual rollers can be positioned relative to one another in the vertical direction to produce the desired roll gap.
- the work rolls are arranged axially displaceable, whereby it is possible to achieve an influence of the strip profile in strip lines by a variable roll gap profile. Also in pre-lanes, the procedural possibility of axial displacement of the work rolls has significance, on the one hand for the purpose of targeted strip profile influencing, on the other hand for the extension of the roll travel through targeted wear distribution.
- the rolling device As described in WO 2005/011884 A1, is that there are means for bending or balancing the work rolls. As a result of this, a bending moment can be introduced into the work rolls, which has procedural advantages.
- the work roll bending and displacing systems are housed in fixed blocks in which the adjusting means required for bending and balancing or axial displacement are arranged. These offer the advantage of fixed pressure medium feed lines, which do not have to be separated when changing work rolls.
- the negative influence of this frictional force increases with decreasing height of the vertical guides of the bending device.
- the height of the guides is directly related to the roll diameter, ie for small roll diameters, the negative influence of the resulting frictional force is greater than for large roll diameters.
- the invention is therefore based on the object, a rolling device of the type mentioned in such a way that the disadvantages mentioned eliminated or at least reduced, that in particular the self-weight influences of the Axialverschiebesch be reduced in terms of the force exerted on the guides of the bending means frictional forces.
- the axial displacement means are preferably arranged indirectly via a connecting frame on the rolling stand. They can be arranged with their second operative end in a locking block, which is arranged in the direction of displacement of the Axialverschiebesch movable in or on the bending means.
- a further development provides that an effective positive locking connection between the locking block and the roll chock in the direction of displacement of the axial displacement means is produced by the articulated connection in the form of a locking bolt.
- at least one recess congruent with the shape of the locking bolt can be incorporated in the roll chock.
- the locking block may be mounted in or on the bending means at a location spaced from the first operative end by means of a guide.
- the guide preferably has a link in which a bolt connected to the bending means is arranged.
- the gate is advantageously designed as a groove-shaped recess extending in the direction of displacement of the axial sliding means.
- the Axialverschiebesch preferably have a hydraulic piston-cylinder system.
- the first and / or second action end of the axial displacement means may be slidably disposed on the Axialverschiebeschn and / or on the guide. This makes it possible in a simple manner to be able to adjust the pivot points with additional roll displacement in the horizontal rolling direction.
- the generation of a torque in the guides of the bending device is minimized independently of the diameter of the roller or the available overall height. As a result, the above adverse consequences are reduced. In particular, the control behavior of the bending device is improved.
- Fig. 2 shows the section A-A of FIG. 1, wherein the bending means are not shown.
- a rolling device 1 - partially only partially - shown which is constructed in a conventional manner.
- roll chocks 2 Two work rolls, not shown, are held by roll chocks 2, one of which can be seen in FIG.
- the roll chocks 2 are mounted in a roll stand (or roll stand) 3.
- the work rolls are axially displaced both in a direction of displacement x and acted upon by a bending moment can be.
- known Axialverschiebesch 4 and bending means 5 are provided.
- the Axialverschiebesch 4 have to force a hydraulic piston-cylinder system 16.
- the axial displacement means 4 have two ends 6 and 8, between which they can generate their displacement force in the displacement direction x.
- the first operative end 6 located on the right in the figures is fixed by means of an articulated connection 7 in the form of a bolt to a connecting frame 10, which in turn is fastened to the rolling stand 3.
- the axial displacement means 4 are also hinged articulated, by means of an articulated connection 9 in the form of a locking bolt.
- the locking pin 9 is mounted in a locking block 11 so that upon displacement of the Axialverschiebesch 4, the locking block 11 is moved with.
- the locking bolt 9 passes through the locking block 11 (see Fig. 1) and engages in a recess 12 which is incorporated in the roll chock 2. This has the consequence that upon a displacement of the axial displacement means 4, the movement is transmitted via the locking block 11 to the roll chock 2 and thus to the roll; the roller is then displaced axially in the displacement direction x.
- a recess 17 is incorporated in the bending means 5, in which the locking block has 11 place and is movable in the displacement direction x.
- a guide 13 is accommodated, which is mounted with its one end (left in the figures) by means of a link 14 and a bolt 15 which is fixed in the bending means 5.
- the gate 14 is - as shown in Fig. 2 can be seen - designed as an extending in the direction of displacement x groove.
- the bolt 15 supports the guide 13 at its one end. If the bending means 5 move up and down in the vertical direction V on vertical guides 18 (see Fig.
- the bending means 5 and the axial displacement means 4 are arranged separately from one another.
- the bending means remain - compared with previously known solutions - largely unchanged in their function and mechanical design of the components.
- the guides 13 are mounted, in which the locking block 11 is running.
- the tool ingot pieces 2 are coupled to the axial displacement means 4 via the locking block 11.
- the guides 13 are based on the running in the gate 14 bolt 15 on the bending means 5 from.
- a corresponding displacement of the pivot fulcrums can be provided.
