Description

Die Erfindung betrifft ein Walzgerüst für bahnförmiges Walzgut, insbesondere zum reversierenden Walzen, mit zwei Arbeitswalzen, zwischen denen das Walzgut geführt wird und mit jeder dieser Arbeitswalzen zugeordneten Stützwalzen, wobei sowohl die Stützwalzen wie auch die Arbeitswalzen jeweils in Einbaustücken gelagert sind und den Stützwalzen Biegeblöcke zugeordnet sind.The invention relates to a roll stand for sheet-like rolling stock, in particular for reversing rolling, with two work rolls, between which the Rolled material is guided and assigned to each of these work rolls Back-up rolls, both the back-up rolls and the work rolls each in Chocks are stored and the support rollers are assigned bending blocks.

Ein derartiges Walzgerüst ist aus der DE 33 27 433 C2 bekannt.Such a roll stand is known from DE 33 27 433 C2.

Beim Walzen von Band sind die unterschiedlichsten Eigenschaften des Bandmaterials zu beachten, sei es durch die Erzeugung unterschiedlich dicker Bänder, oder Bänder mit unterschiedlichen Breiten oder die Bearbeitung unterschiedlicher Materialqualitäten. Diese Eigenschaften wirken sich insbesondere beim Einsatz von Arbeitswalzen mit vergleichsweise geringem Durchmesser aus, weil die Arbeitswalzen dann unterschiedliche Durchbiegungen erreichen. Diesen Durchbiegungen muss durch entsprechende Voreinstellung der Arbeitswalzen entgegengewirkt werden.
Bei der DE 33 27 433 C2 sind den Arbeitswalzen zum Stützen gegen die Versetzungsrichtung Stützvorrichtungen mit hydrostatischen Stützelementen zugeordnet, die mit hydrostatischen, den zu stützenden Flächen zugewandten Drucktaschen versehen sind und parallel zur Längsachse der jeweils zu stützenden Arbeitswalze angeordnet und steuerbar ausgebildet sind. Die Stützwalzen sind hierbei als Durchbiegungseinstellwalze mit einem um einen Träger mittels Stützelementen abgestützten Walzenmantel ausgeführt. Die Arbeitswalzen sind mit den diesen zugeordneten Stützvorrichtungen im Walzgerüst parallel zur Walzgutbahn horizontal verschiebbar.When rolling strip, the most varied properties of the strip material have to be taken into account, whether by producing strips of different thicknesses, strips with different widths or processing different material qualities. These properties have an effect particularly when using work rolls with a comparatively small diameter, because the work rolls then achieve different deflections. These deflections must be counteracted by appropriately pre-setting the work rolls.
In DE 33 27 433 C2, the work rolls for supporting against the direction of displacement are assigned support devices with hydrostatic support elements, which are provided with hydrostatic pressure pockets facing the surfaces to be supported and are arranged and designed to be controllable parallel to the longitudinal axis of the work roll to be supported. The support rollers are in this case designed as a deflection adjustment roller with a roller jacket supported around a carrier by means of support elements. The work rolls can be moved horizontally with the support devices assigned to them in the roll stand parallel to the rolled material web.

Ebenfalls horizontal verschiebbar sind die in Einbaustücken gelagerten Arbeitswalzen gemäß der EP 0 233 597 B1, wobei die Verschiebung in diesem Fall durch Lenkeranordnungen erfolgt, die durch als Exzenter ausgebildete Schwenkbolzen geführt und in ihrer Bewegung einstellbar sind.The ones stored in chocks can also be moved horizontally Work rolls according to EP 0 233 597 B1, the displacement in this Case is carried out by handlebar arrangements by trained as an eccentric Swivel pins are guided and their movement is adjustable.

Unabhängig davon ist es aus der EP 0159 796 A1 bekannt, Einfluss auf die Durchbiegung der Arbeitswalzen in Richtung bzw. entgegen der Richtung der Bewegung des Walzgutes zu nehmen.Irrespective of this, it is known from EP 0159 796 A1 to influence the Deflection of the work rolls in the direction or against the direction of the To take movement of the rolling stock.

Aufgabe der Erfindung ist es, mit einfachen Mitteln den Versatz der Arbeitswalzenachsen aus der Ebene der Stützwalzenachsen in einem relativ großen Bereich zu ermöglichen, um damit den unterschiedlichsten. Durchbiegungen entgegentreten zu können.The object of the invention is to offset the offset by simple means Work roll axes from the level of the backup roll axes in a relative large area to allow for the most varied. To be able to face deflections.

Gelöst wird diese Aufgabe erfindungsgemäß bei einem Walzgerüst der im Oberbegriff des Anspruchs 1 genannten Art dadurch, dass die Biegeblöcke mit den Einbaustücken der Stützwalzen verbunden sind und dass die in den Einbaustücken gelagerten Arbeitswalzen durch an den Biegeblöcken angreifende Verstellmittel zusammen mit den Biegeblöcken achsparallel um die Stützwalzenachsen schwenkbar sind.This object is achieved according to the invention with a roll stand in Preamble of claim 1 mentioned type in that the bending blocks with the chocks of the backup rollers are connected and that in the Workpieces stored by chucks on the bending blocks attacking adjustment means together with the bending blocks parallel to the axis Back-up roller axes are pivotable.

Die Erfindung soll nachfolgend an einem Ausführungsbeispiel erläutert werden, wobei in der Figur ein Reversiergerüst schematisch dargestellt ist.The invention will be explained below using an exemplary embodiment, wherein a reversing frame is shown schematically in the figure.

Die Stützwalzen 1 sind in Einbaustücken 2 gelagert und können durch Hydraulikzylinder 6 um ihre Achsen geschwenkt werden. Die Anstellung der oberen und unteren Stützwalze erfolgt in bekannter Weise durch Zylinder 14 bzw. 15. Die obere Stützwalze wird mit dem Zylinder 9 ausbalanciert.
Die Hydraulikzylinder 6 sowie die Zylinder 9 zum Ausbalancieren für die obere Stützwalze sind in Zylinderblöcken 7 befestigt.
Die Stützwalzeneinbaustücke 2 werden in den Gleitsteinen 10 und Schleißplatten 11 gehalten. Die Gleitsteine werden vertikal in den Schleißplatten 12 und 13 geführt. The support rollers 1 are mounted in chocks 2 and can be pivoted about their axes by hydraulic cylinders 6. The upper and lower back-up rolls are adjusted in a known manner by cylinders 14 and 15, respectively. The upper back-up roll is balanced with the cylinder 9.
The hydraulic cylinders 6 and the cylinders 9 for balancing the upper support roller are fastened in cylinder blocks 7.
The backup roll chocks 2 are held in the sliding blocks 10 and wear plates 11. The sliding blocks are guided vertically in the wear plates 12 and 13.

Die Arbeitswalzen 3 sind ihrerseits in Einbaustücken 4 gelagert, wobei diese mit Biegeblöcken 5 verbunden sind, die ihrerseits in den Stützwalzeneinbaustücken 2 fixiert sind. An den Stützwalzeneinbaustücken 2 sind Verstellmittel 8 angelenkt, wobei diese bei diesem Ausführungsbeispiel mit den Hydraulikzylindern 6 betätigt werden. Mittels dieser Hydraulikzylinder 6 kann auf die Biegeblöcke 5 eine im Wesentlichen horizontale Kraft aufgebracht werden, die zu einem Verschwenken der Biegeblöcke und damit der mit diesen verbundenen Einbaustücke 4 der Arbeitswalzen 3 führt. Wie ersichtlich, wirken diese Verstellmittel von beiden Seiten auf die Biegeblöcke ein, so dass ein Verschwenken dieser in beiden Richtungen achsparallel um die Stützwalzenachsen möglich ist. Auf diese Weise kann der unterschiedlichen Durchbiegung der Arbeitswalzen beim Reversieren entgegengewirkt werden.The work rolls 3 are in turn stored in chocks 4, these with Bending blocks 5 are connected, which in turn in the support roller chocks 2 are fixed. Adjustment means 8 are articulated on the support roller chocks 2, this in this embodiment with the hydraulic cylinders 6 be operated. By means of these hydraulic cylinders 6, the bending blocks 5 can be a substantially horizontal force is applied, leading to a Swiveling the bending blocks and thus those connected to them Chocks 4 of the work rolls 3 leads. As can be seen, these work Adjustment means from both sides onto the bending blocks so that a Swivel this in both directions axially parallel to the Back-up roller axes is possible. In this way, the different Deflection of the work rolls can be counteracted when reversing.
