Definitions

  • the invention relates to a device for aligning the upper edge of the lower work roll of roll stands, in particular four-high stands to the rolling line by means of a pair of wedges below each lower roll chock, consisting of a lower wedge element that can be moved horizontally in the direction of the roll axis and an upper wedge element that can only be moved in the vertical direction which lie on one another with their wedge surfaces during the rolling process.
  • truss cylinders are arranged as lifting devices for the chocks in the uprights, which necessitate complex machining of the uprights (DE-A-28 06 525).
  • the European patent EP-B-02 31 445 has disclosed a device for height adjustment of rolls in roll stands, in which a pair of wedges is arranged in a generic manner under each chock of the support roll, with which a stepless height compensation of the roll can be achieved, that the lower wedge is displaceable in the horizontal direction and the upper wedge is displaceable in the vertical direction.
  • one of a plurality of differently sized adapters is inserted between the upper wedge and the underside of the support roller chock, the height of which can be successively stepped by means of a step-by-step shifting into the working position.
  • a step-like compensation of the work roll position can be carried out by inserting the different height pieces, while the wedge arrangement serves to bridge the step heights.
  • the known device is very complex due to the side-by-side arrangement of displaceable adapters and wedges and also requires sufficient space to accommodate the differently graduated adapters.
  • the present invention is based on the object of simplifying a generic device in such a way that with simple and, above all, space-saving devices, the upper edge of the lower work roll can be adequately matched to the rolling line.
  • each upper wedge element can be raised and lowered together with the respective roller chock by means of a lifting device and that the wedge surfaces of both wedges are stepped, the steps intermeshingly supporting the wedge elements vertically.
  • the essence of the present invention is to link the upper wedge element itself on the one hand with the lifting element for the chock of the roller to be lifted and on the other hand to use it at the same time for supporting the chock at the desired height.
  • By lifting the upper wedge element itself it becomes possible to move the lower wedge element into the desired position and then to place the upper wedge element thereon. So that the wedges can self-lock, the wedge surfaces are stepped. This allows the wedges to be made very short, which means that the displacement path can be kept extremely short. This creates an extremely simple and also robust device which can be accommodated in the roll stand in a space-saving manner.
  • the upper wedge element is part of a cross-member which overlaps the lower wedge element and can be raised and lowered by means of piston-cylinder units arranged laterally next to the lower wedge element, the respective Roller chock rests on the crossbar and the crossbar is guided in the vertical direction.
  • the proposed solution enables the lifting device designed as a piston-cylinder unit to be arranged outside the displacement path of the lower wedge elements.
  • the piston-cylinder units can, for example, be flanged to the side of the roll stands.
  • the piston-cylinder units are clearly visible and therefore easy to inspect.
  • the respective chock rests on the trusses, on the underside of which the upper wedge element is formed.
  • the guide for the traverse consists of at least two guide bolts which are encompassed by corresponding vertical bores in the traverse.
  • 1 denotes the lower support roller of the four-high mill stand, which is otherwise not shown.
  • the back-up roller is mounted on both sides in chocks 2 and 3, which in turn are guided in the roller stand 4 so that they can be raised and lowered.
  • the device mainly consists of the lower wedge elements 5 and the upper wedge elements 6, which are shown in the right half of the figure and are only indicated in the left half.
  • Both wedge elements 5, 6 are provided with small steps which replace the flat wedge surfaces which are otherwise customary with wedges. These steps are of identical design on both wedges 5, 6 and fit well into one another so that the upper wedge element 6 rests securely on the lower wedge element 5 and can absorb large horizontal forces.
  • each lower wedge element 5 can be displaced in the horizontal direction parallel to the axial direction of the support roller 1 with the aid of a drive, the two lower wedge elements being connected to one another via tension elements 8 and thus being moved in synchronism.
  • Each upper wedge element 6 is formed on the underside of a crossmember 9, the shape of which can be clearly seen in the plan view in FIG.
  • the crossbeams 9 on both sides are of identical dimensions and consist of a body which is double T-shaped in plan view and which engages over the lower wedge element 5.
  • four piston-cylinder units 10 are arranged, with which the crossmember 9 and with it the chocks 2 and 3 seated on it can be raised.
  • the lower wedge elements When the crossbar is raised, the lower wedge elements can be inserted or extended under the upper wedge elements 6 by transverse displacement with the aid of the drive 7, so that after lowering the crossbar with the upper wedge elements 6, the height of the support roller and the work roller arranged above it can be varied.
  • bolts 12 are provided which extend vertically on the lower framework 4 and have corresponding bores in them penetrate the truss 9. The bolts or the bores only permit vertical movement of the cross member and thus also of the upper wedge elements 6.
  • piston-cylinder units 10 The arrangement of the piston-cylinder units 10 in relation to the crossmember can be seen in FIG. It can clearly be seen that the piston-cylinder units 10 do not impede the path of movement of the lower wedge elements 5 because they are arranged laterally next to them.
  • extension rails 13 for the roller set are arranged laterally next to the device according to the invention, on which - as shown - wheel sets roll, which are provided on the lower chocks of the support roller 1.
