Definitions

  • the invention relates to a rolling device with two work rolls, which are mounted in each case by means of work roll chocks in a rolling stand, wherein the work roll chocks in the rolling stand via at least one Agriculturewalzenverriegelung are locked and unlocked, at least two other rollers, in particular two support rollers, each supported by means of roll chocks in the rolling mill are, wherein both at least one of the work rolls and at least one of the other rolls in the roll stand for setting a desired roll gap relative to the other work roll or the other further roll, in particular in the vertical direction, are adjustable, the work rolls with Axialverschiebeschn for axial displacement are provided, with which the work rolls can be brought relative to the rolling stand in a desired axial position and held there, and wherein the work rolls with bending means in operative connection with which they can be acted upon with a bending moment.
  • a rolling apparatus of this kind is well known in the art. It is exemplified on the EP 0 256 408 A2 , the EP 0 256 410 A2 , the DE 38 07 628 C2 and the EP 0 340 504 B1 pointed. Rolling devices are known from these documents, in which two work rolls, which are located at a defined distance from one another, form the roll gap required for rolling and are supported on support rolls or intermediate rolls. The thus formed rolling device is thus equipped as a device with four or six rollers, wherein the individual rollers are positioned relative to each other in the vertical direction to produce the desired nip.
  • the work rolls are arranged axially displaceable, whereby it is possible to effect an influence of the strip profile in strip lines by a variable roll gap profile.
  • Vorstrassen wins the procedural possibility for axial displacement of the work rolls in importance, on the one hand for targeted Bandprofilbeeinlung, on the other hand to extend the roll travel through targeted wear distribution.
  • Another important embodiment of the rolling apparatus is that there are means for bending or balancing the work rolls. Through this, a bending moment can be introduced into the work rolls, which has procedural advantages, as can be seen from the aforementioned literature.
  • the work roll bending and displacement systems usually have stationary blocks in which the adjusting means required for bending and balancing or axial displacement are arranged. These offer the advantage of fixed pressure medium supply lines, which do not have to be separated during the work roll change.
  • the required plunger are either stationary in stationary blocks arranged, which leads disadvantageously to not negligible tilting moments in the axial displacement, or they are designed as with the axial displacement mitverschiebenden cartridges to the tilting moments or friction forces better to master.
  • the prior art rolling devices reach their limits in terms of process engineering when high roll uprights are required, as required, for example, in sheet metal or pre-lines.
  • the plunger of the bending or Balancierzylinder must be performed over much longer lengths and thus require a lot of space to ensure the lever ratios occurring at long distances, even with fully extended ram.
  • Short guide lengths of the plunger of the bending or Balancierzylinder be achieved again when the bending or Balancierzylinder with the system Häwalzen- / Stützwalzeneinbau the ride, so to speak "flying" between in downwardly projecting arms of the support or Eisenwalzeneinbau matterss and laterally cantilevered tabs of the work roll chock are arranged.
  • the plunger can be arranged either in the support or Eisenwalzeneinbau 1:1 or in the work roll chock; its arrangement in the support or intermediate roll chock offers the advantage that the Druckstoffzuschreibtechnischtechnischmaschinen need not be separated when changing work rolls.
  • Such a solution with "flying" arranged bending or Balanciersystem in combination with an axial displacement is from the DE 101 50 690 A1 known.
  • the axial displacement of the work roll is realized by a coaxially arranged on the work roll chock displacement cylinder.
  • the displacement cylinder and the work roll set thereby form a structural unit and are installed together in the rolling stand.
  • the invention is therefore based on the object to provide a rolling device with bending and Axialverschiebesystem for the work rolls, which on the one hand permits high roll uprights, on the other hand, is characterized by a small space requirement in relation to the stand window height. Furthermore, a good guidance of the plunger of the bending or Balancierstoff should be ensured, while at the same time care should be taken that the number the operating change parts in the case of a work roll change is as low as possible. In addition, the related requirements of the axial Häwalzenverriegelung and the position measurement of Axialverschiebeweges should be met.
  • This object is achieved in that the Axialverschiebesch between rolling stand and work roll locking are arranged or act and the bending means between the work roll chock and the other roll chock are arranged or act.
  • a first further development provides that the further roll chock, that is to say that of the support roll, has a guide in which the work roll chock is arranged so as to be displaceable relative to the further roll chock and fixable.
  • the axial displacement means are preferably fixedly arranged on the roll stand and have at least one linear guide on which the work roll chock is arranged to be displaceable relative to the axial displacement means in a direction transverse to the axial displacement direction, in particular displaceable in the vertical direction, and fixable.
  • this has two webs extending on both sides of the axis of the work roll, which webs can be locked with one axial displacement means each.
  • the linear guide is fixedly mounted on Axialverschiebesch and in a direction transverse to Axialverschiebichtung, in particular in the horizontal direction, displaceable, preferably plate-shaped, bar, which together with the linear guide for the end of the web forms a receiving slot.
  • the bolt can be in communication with actuating means, by means of which it is positionable in two layers, namely in a locking position and in an unlocking position.
  • the actuating means per Axialverschiebesch preferably consists of two hydraulic piston-cylinder systems, which are arranged parallel to each other and can move the bolt, the piston-cylinder systems on the side facing away from the work roll chock side of the bolt attack on this.
  • the Axialverschiebesch are equipped according to a development with means for preventing twisting, which prevent rotation of the axial ends of the Axialverschiebesch.
  • At least one bending means designed as a hydraulic linear actuator is arranged in a cantilever arm of the further roll chock and presses on a laterally projecting tab of the work roll chock. It can be arranged between the bending means and the laterally projecting tab of the work roll chock a sliding surface.

  • the webs 12, 13 are received at their end 15 and 16 in the locked state in a receiving slot 17 which extends in the vertical direction and offers the possibility that the work roll chock 3 and thus the work roll 2 vertically positioned at that level in the rolling stand 4 and can be set, which corresponds to the required roll gap.

  • the sliding sleeve 28 consists of a sliding tube with guide bushes and a cubically shaped lid 29. With this cover 29 of the displacement piston 30 is coaxially fixed.
  • the sliding tube of the sliding sleeve 28 has laterally projecting guide straps 31 which slide on a T-piece 32 connected to the fixed block 27 (see Fig. 1).
  • means 21 for preventing twisting of the axial displacement means 8 are provided, i. H. a torsion of one axial end 22 relative to the other axial end 23 of the Axialverschiebeschs 8 is excluded.
  • a displacement measuring system 33 is arranged between the base of the T-piece 32 and one of the guide plates 31. With this it is possible to measure the current axial position of the work rolls 2.
  • the work roll latch 5 On the outside of the lid 29 of the sliding sleeve 28, the work roll latch 5 is attached. This consists essentially of a base plate 34 (see Fig. 1 and 4), the latch 14 and actuating means 18 for the bolt 14.

Solutions for work roll displacement devices above the roll line are problematic at high altitude. Solutions for work roll shifters under the rolling line can be built conventionally or as such for large rises.
  • the devices on the inlet and on the outlet side are substantially identical and symmetrical to each other, so that - as already in the case of the first embodiment - are described here only representative of the rolling line Axialverschiebesch 8 with high rising.
  • the configuration of the Axialverschiebeschs 8 also corresponds to that of the embodiment described above. Referring to FIGS. 8 to 12, it can be seen that the lid 29 is fixed to the displacement piston 30 connected is. He stands at least in the direction of the work roll chock 3 against the local outer contour of the sliding sleeve 28 before. Between the cover 29 and arranged on the sliding sleeve 28 plate 37 of the bolt 14 is installed, which surrounds the sliding sleeve 28 and can be moved to close the locking in approximately horizontal direction transverse to the axis of the sliding sleeve 28. Between the plate 37 and the latch 14 is formed by the closing of the bolt 14 of the vertically extending receiving slot 17, in which the laterally projecting web 12, 13 of the work roll chock 3 is guided. For this purpose, a recess is incorporated in the plate 37 or between plate 37 and bolt 14, a spacer is inserted with a comparable recess.
  • the vertically extending receiving slot 17 receives the axial displacement forces that must be passed through the laterally projecting webs 12, 13 of the work roll chock 3, while allowing large relative movements in the vertical direction. This allows a large roll rise as a result.
  • the contact surfaces of the webs 12, 13 on the plate 37 and the bolt 14 thereby form two abutments for the webs 12, 13 of the work roll chock 3.
  • the vertically extending receiving slot 17 is opened to the work roll removal by the bolt 14 is withdrawn. Then the work roll set can be pulled out to the operating side.
  • the plate 37 on the sliding sleeve 28 has two main functions. On the one hand, it serves as one of the two abutments for the webs 12, 13. On the other hand, it is part of means 21 for preventing a rotation of the Axialverschiebesch. 8
  • a component which is mounted outside the central axis, the sliding sleeve 28 fixed to the stand. This sticks out in one Opening of the plate 37 on the sliding sleeve 28 into it, or a component attached to the plate 37 of the sliding sleeve 28 protrudes into a stationary opening.
  • the anti-rotation device must have a guide of sufficient length, so that a rotation between the two axial ends 22 and 23 of the Axialverschiebeschs 8 is prevented for the entire maximum displacement.
  • the sliding sleeve 28 and the displacement piston 30 may be formed so that they do not slide on each other with cylindrical surfaces, but with such surfaces that prevent rotation to each other.
  • the fulfillment of the two main functions of the plate 37 on the sliding sleeve 28, namely to be both abutment and part of the rotation, can be achieved by two separate, worked on the sliding sleeve 28 or welded plates.
  • the combination of the two functions by means of the plate is easy to manufacture and therefore advantageous.
  • the detailed embodiment of the work roll latch 5 by means of the bolt 14 is shown in Figures 10 and 12.
  • the latch 14 may have an O- or U-shaped recess (in Fig. 10, the recess is O-shaped).
  • the latch 14 is not arranged in front of the head 29, but it surrounds the sliding sleeve 28.
  • the recess in the bolt 14 is so large that the bolt for mounting in training in the O-shape axially or when executed in U-shape axially or radially can be pushed onto the sliding sleeve 28.
  • the U-shape is as a closed mold, the stiffer design of the bolt 14.
  • the U-shape has the advantage that the cover 29 can be permanently connected to the sliding sleeve 28 or that the cover 29 and the sliding sleeve 28 may consist of one piece ,
  • the latch 14 When executed in U-shape, the latch 14 is open on the side of the sliding sleeve 28 which is opposite to the work roll chock 3. Because the latch 14 surrounds the sliding sleeve 28, the web 12, 13 of the Work roll chock 3 - measured from the middle of the work roll bearings - shorter than if the bar 14 were located in front of the head 29. Thus, the lever arm between the work roll bearing and the guide, which is formed by the two abutment bar 14 and plate 37 decreases. A smaller lever arm has the consequence that the frictional forces in the guide exercise only relatively small additional moments on the work roll bearings. The work roll bearing thus has a longer life.
  • the closing and opening of the receiving slot 17 for the laterally projecting webs 12, 13 of the work roll chock 3 is accomplished by a horizontal or approximately horizontal movement of the bolt 14, the locking stroke. Therefore, the recess in the bolt 14 in the direction of movement (horizontal) at least by the locking stroke is greater than is required for assembly.
  • the movement of the bolt 14 is effected by actuating means 18.
  • This is z. B. one or more actuators in the form of piston-cylinder systems 19, 20 (hydraulic cylinder with continuous piston rods).
  • the piston-cylinder systems 19, 20 expediently put on the side facing away from the work roll chock 3 of the bolt 14. It is particularly space-saving, if two piston-cylinder systems 19, 20 find space at the top and bottom in recesses of the bolt 14 and on the plate 37 or on the lid 29 are attached.
  • FIG. 10 Fig. 12 shows a piston-cylinder system 19, 20 in detail.
  • the bolt 14 has three recesses in the embodiment of FIG. 10, a large for the sliding sleeve 28, two smaller for the piston-cylinder systems 19, 20 and another to avoid collision with the means 21 for preventing the rotation of the Axialverschiebeschs 8.
  • the latch 14 is held by the piston-cylinder systems 19, 20 in the open or closed position. But it must also be secured against rotation against an axis parallel or identical to the central axis of the sliding sleeve 28.
  • strips 38, 39 are mounted, which prevent such rotation.
  • the strips 38, 39 can also form a common component with the plate 37 or with the plate 37 and the displacement sleeve 28.
  • An alternative embodiment of the rotation is obtained when 29 horizontal grooves are formed in the plate 37 or in the lid, in which raised strips of the bolt 14 are guided. Furthermore, it is possible to mold the grooves in the bar 14 and to attach the raised strips on the plate 37 or on the lid 29. Variants in which the rotation against the plate 37 are mounted, have the advantage that the lid 29 is then not additionally claimed to twist.
  • the cover 29 of the sliding sleeve 28 is shaped so that two functions can be fulfilled: First, the sliding piston 30 is coaxially fixedly connected to the cover 29 (see Fig. 8), so that the piston above the cover the sliding sleeve 28 including attachments and thus also the vertically extending receiving slot 17 for the work roll chock 3 can move axially.

  • the measurement of the Axialverschiebewegs is made possible by a out of or within the Axialverschiebesch 8 unit.
  • the arrangement of the transmitter within the printing system is avoided as possible due to risk inclination during maintenance.
  • the displacement measuring system 33 can be formed as an external unit or as an internal unit. In the case of an external unit, protection against harmful environmental influences is required, which can be achieved by a sealed, hydraulic cylinder-like system.
  • a type of piston fixedly mounted on the stator slides through a cylinder tube fixed to the moving parts of the axial displacement. Coaxially with the cylinder tube, the transmitter moves and generates the corresponding path signal. With appropriate sealing and stripping elements a sufficient protection of the system is achieved.
