Definitions

  • the invention relates to a roll stand with rollers which can be set in two mutually parallel roll stands, of which the operator-side roll stand can be moved away from the other roll stand, in particular a universal roll stand with horizontal rolls and vertical rolls arranged in cassettes.
  • a roll stand of this type is already known from WO-A-88/06930.
  • the upper cross yoke is divided into two in a universal stand construction known from DE-C-30 39 203, so that it swings out and back again after the roll change and can be locked with the rest of the scaffolding. In the swung-out position, these are the rollers mounting chocks freely accessible and can be removed from the scaffolding via the window recesses.
  • additional swiveling mechanisms are required, e.g. B. in the form of hydraulic swing cylinders.
  • the roll change is simplified in that the horizontal rolls are accommodated without assembly from bearings arranged in the roll stands, the operator-side roll stand facing away from the drive elements with the bearings in the roll axis direction of the horizontal rolls can be moved away from the other roll stand and in cassettes stored vertical rollers are inserted in guides firmly connected to the roller stands. After the operator-side roll stand has been moved, not only the horizontal but also the vertical rolls are exposed and are accessible from the inside of the pulled-apart roll stand.
  • the cassette carrying the vertical rollers can thus be brought directly into the installation position in the roller stand required for the rolling operation, namely by inserting it into the guide, so that no additional pieces are required.
  • the object of the invention is to further simplify the roll change in a generic roll stand, in particular a universal roll stand, and to reduce the downtimes of the rolling train during the roll change.
  • an interchangeable frame which can be moved away with the operator-side roller stand accommodates the rollers. With a duo roll stand, these are the vertical or horizontal rolls, and with a universal roll stand, these are both the horizontal and the vertical rolls. After moving away the operator-side roll stand, the with the interchangeable frame is locked, for which purpose the interchangeable frame preferably has latching recesses for engaging and disengaging locking lugs of the operator-side roller stand, the interchangeable frame, designed as a dashboard at the same time, can be completely replaced, provided that it has been unlocked beforehand.
  • the removable frame with the rollers By moving the operator-side roller stand in its end position, the removable frame with the rollers is in an intermediate position, for. B. on the foundation or on rails, completely free. It is therefore accessible to a crane or a transfer platform with which the removable frame containing all wear parts (vertical and horizontal rollers as well as fittings or profile-dependent parts) can be removed from the rolling mill.
  • the separation of the roller set therefore no longer needs to be carried out in the rolling train, but rather can be carried out in a conversion hall without disturbing the further operational sequence.
  • a very simple, quick roll change can be achieved, as is otherwise only possible with changeable stands, but which always require that several stands be kept in reserve, which causes correspondingly high costs.
  • the interchangeable frame with the roll bundles of the upper and lower horizontal roll supports, z. B. sheet steel structures is provided.
  • the positions are opened up so that there is sufficient free space to allow the trays, which are preferably designed as pivot levers for the upper horizontal roller, to be pivoted into their position, which engages under the roller bundles and thus supports the roller or the roller ring.
  • Any pivot drive is suitable for pivoting the lever, e.g. B. hydraulic cylinders hinged to the swivel levers.
  • The are during the rolling operation Swivel lever in an out-of-operation position, removed from the roll collar or journal, whose diameter, which is not subject to wear, is always used for storage when changing the roll. Since the shelves for the lower horizontal roller do not interfere with the rolling operation, they can be rigidly connected to the change frame, e.g. B. train as lugs.
  • the removable frame protrude into the roll stand in the area of the vertical rolls with the lugs receiving the cassette.
  • the cassette is therefore at the scene, i.e. inserted into the approaches that form an integral part of the removable frame.
  • a universal roll stand 1 shown in FIG. 1 has a roller stand 3 on the drive side, which is connected to the foundation 2 via a base plate, and a movable roller stand 4 on the operator side.
  • the roller stands 3, 4 are arranged parallel to one another , and to move away or - can move to the operator-side roller stand 4, a displacement cylinder, not shown, with its piston rod.
  • the position of the operator-side roller stand 4 moved away from the roller stand 3 is shown in FIG. 2 - there in an intermediate position - and in FIG. 3 - there in the end position.
  • an upper and a lower horizontal roll 5, 6 and two vertical rolls 7 are arranged without an assembly.
  • the horizontal rollers 5, 6 are constructed in several parts. They consist of two support shafts, one of which is mounted in the roller stand 3 on the drive side and the other in the roller stand 4 on the operator side; they enclose a rolling ring 8 between them and are clamped to one another via tie rods 9. There are also four thinner tie rods 11, by means of which the two roller stands 3, 4 are braced together. Adjusting drives 12 are used to position the horizontal rollers 5, 6 or the rolling rings 8, with which the horizontal rollers 5, 6 can be removed from one another or brought closer to one another, depending on the direction of rotation of the drives 12.
  • Both the horizontal rollers 5, 6 or their rolling rings 8 and the vertical rollers 7 are arranged in an interchangeable frame 13 which is hydraulically locked to the movable, operator-side roller stand 4; for this purpose, it has locking recesses 14 (see FIG. 3) into which locking lugs 15 fastened to the roller stand 4 can be locked. Furthermore, the interchangeable frame 13 is provided with fitting supports 16 (see FIG. 4) which accommodate the fittings required for the operation of the rolling stand 1.
  • the vertical rollers 7 are each in a cassette 17 (see FIG. 4), which is arranged in the lugs 18 projecting into the roller stands 3, 4; in FIG. 4, the lugs 18, which have the guides 19 for the cassette 17, extend in the direction of the plane of the drawing into the windows of the roller stands 3, 4. In the operating state of the universal roll stand 1 shown in FIG. 1, the vertical rolls 7 are connected to roll positions 21.
  • the interchangeable frame 13 is also provided with stationary trays 22 assigned to the lower horizontal roller 6 on the one hand, and to the upper horizontal roller 5 assigned as a pivot lever 23, on the other hand.
  • Each pivot lever 23 is connected to the piston rod 25 of a hydraulic adjusting cylinder 26 via an intermediate lever 24 (cf. FIG. 4).
  • the horizontal rollers 5, 6 are mounted in eccentric sleeves 28 which are connected to the horizontal roller adjustment 12.
  • the positions of the horizontal rolls 5, 6 are moved apart as far as possible.
  • the lower horizontal roller 6 is then supported with its roller bundles 27 on the lower shelves 22 and the upper horizontal roller 5 with its roller bundle 27 on the pivoted lever 23 pivoted out of its inoperative position into the removal position shown in FIG.
  • the movable, operator-side roll stand 4 is then shown in FIG Move the position into the intermediate position shown in FIG. 2 away from the roll stand 3.
  • the locking lugs 15 are pulled out of the latching recesses 14 of the change frame 3, and when the roller stand 3 is moved into its end position according to FIG. 3, all the wear parts remain, i.e. in particular the horizontal rollers 5, 6, the vertical rollers 7 and also the exchangeable frame 13 containing fittings in the intermediate position in which it is on the foundation 2, for. B. hydraulically clamped (not shown), rests.
  • the removable frame 13 can be removed from the rolling mill by means of a lifting device 29 and immediately replaced with a newly equipped removable frame.
  • the separation of the roll set thus no longer takes place in the rolling mill, but in the distant conversion hall, which enables a quick roll change that is not unnecessarily long for the rolling operation.
  • the new removable frame is then assembled in the reverse order of the steps described.
