Description

Biege- und Ausbalanciervorrichtung für axial verschiebbare Arbeitswalzen eines Walzgerüstes Bending and balancing device for axially displaceable work rolls of a roll stand
Die Erfindung betrifft eine Biege- und Ausbalanciervorrichtung für axial verschiebbare Arbeitswalzen eines Walzgerüstes, insbesondere eines Quarto- walzgerüstes, wobei beidseitig im Fenster jedes Walzenständers Führungsblöcke im Höhenbereich der Arbeitswalzeneinbaustücke vorgesehen sind und die Kraft von Biege- und Balancierzylindern auf die in Achsrichtung und vertikal verschiebbar geführten Arbeitswalzeneinbaustücke übertragen.The invention relates to a bending and Ausbalanciervorrichtung for axially displaceable work rolls of a rolling mill, in particular a Quarto rolling stand, with guide blocks in the height range of the work roll chocks are provided on both sides in the window of each roll stand and the force of bending and Balancierzylindern out in the axial direction and vertically displaceable Work roll chocks are transferred.
Derartige Walzgerüste können in Warm- und Kaltwalzwerken, Steckelwalzwerken und Grobblechwalzwerken vorhanden sein.Such rolling mills can be present in hot and cold rolling mills, Steckel mills and plate rolling mills.
Biege- und Ausbalanciervorrichtungen der vorstehenden Art sind beispielsweise aus der EP 0 256 408 A2 bekannt.Bending and balancing devices of the above type are known, for example, from EP 0 256 408 A2.
Der bisherige Hub der Biege- / Balancierzylinder ist begrenzt, um eine ausrei- chende Führung der Arbeitswalzeneinbaustücke bei großen Arbeitswalzenaufgängen sicherzustellen.The previous stroke of the bending / balancing cylinders is limited to ensure adequate guidance of the work roll chocks in large work roll runs.
Aufgabe der Erfindung ist es eine Biege-und Ausbalanciervorrichtung bereitzustellen, die einen wesentlich größeren Arbeitswalzenaufgang sicherstellt bei gleichzeitiger konstanter, maximaler Führung der Arbeitswalzeneinbaustücke.The object of the invention is to provide a bending and balancing device which ensures a much larger work roll emergence while maintaining constant, maximum guidance of the work roll chocks.
Gelöst wird diese Aufgabe erfindungsgemäß bei einer Biege-und Ausbalanciervorrichtung für axial verschiebbare Arbeitswalzen eines Walzgerüstes, insbe- sondere eines Quartowalzgerüstes, wobei beidseitig im Fenster jedes Walzenständers Führungsblöcke im Höhenbereich der Arbeitswalzeneinbaustücke vorgesehen sind und die Kraft von Biege- und Balancierzylindern auf die in Achsrichtung und vertikal verschiebbar geführten Arbeitswalzeneinbaustücke übertragbar ist, dadurch, dass die Führungsblöcke jeweils in einen oberen und einen unteren Füh- rungsblock unterteilt sind, dass die oberen Führungsblöcke im Fenster des Walzenständers vertikal verschiebbar gelagert sind, dass die unteren Führungsblöcke im Fenster des Walzenständers ortsfest oder ebenfalls vertikal verschiebbar gelagert sind und - dass in jedem der zusammengehörenden oberen und unteren Führungsblöcke ein von diesen geführter Biege- und Balancierzylinder angeordnet ist, der mit dem oberen und dem unteren Arbeitswalzeneinbau- stück in Eingriff steht.This object is achieved according to the invention in a bending and balancing device for axially displaceable work rolls of a roll stand, in particular a quarto roll stand, wherein on both sides in the window of each roll stand guide blocks in the height range of the work roll chocks are provided and the force of bending and Balancierzylindern on the axially and vertically displaceably guided work roll chocks is transferable, characterized in that the guide blocks are each block in an upper and a lower guide block in that the upper guide blocks are mounted so as to be vertically displaceable in the window of the roll stand, that the lower guide blocks are mounted fixedly or likewise vertically displaceably in the window of the roll stand, and that in each of the associated upper and lower guide blocks a bending and balancing cylinder guided by them is arranged which engages the upper and lower work roll installation pieces.
Vorzugsweise erfolgt die Kraftübertragung von den Biege- und Balancierzylindern auf die Arbeitswalzeneinbaustücke über an diesen anliegende Druckdeckel.Preferably, the power transmission takes place from the bending and Balancierzylindern on the work roll chocks via pressure applied to this lid.
Als besondere Ausgestaltung ist vorgesehen, dass die Druckdeckel die Ar- beitswalzeneinbaustückohren formschlüssig umklammern oder die Führungsblöcke die Arbeitswalzeneinbaustückansätze.As a special embodiment, it is provided that the pressure covers clasp the work roll installation back-up ears in a form-fitting manner or the guide blocks clamp the work roll installation backstops.
Die fliegende negative- und/oder positive Biegevorrichtung einschließlich Aus- balancierungsfunktion für stationäre und axial verschiebbare Arbeitswalzen, ist somit besonders geeignet für hohe Aufgänge.The flying negative and / or positive bending device including balancing function for stationary and axially displaceable work rolls is thus particularly suitable for high rises.
Kerngedanke der erfindungsgemäßen Lösung ist, dass der bisherige einteilige ortsfeste Führungsblock unterteilt wird in einen oberen beweglichen Führungsblock sowie einem unteren ortsfesten- oder beweglichen Führungsblock. Im oberen oder unteren Führungsblock angeordnet oder mit diesen verbunden ist ein Biege- und Balancierzylinder, der gleichzeitig auf die obere und untere Arbeitswalze wirkt und dabei im jeweilig anderen Führungsblock geführt ist.The core idea of the solution according to the invention is that the previous one-piece stationary guide block is divided into an upper movable guide block and a lower stationary or movable guide block. Arranged in or connected to the upper or lower guide block is a bending and Balancierzylinder which acts simultaneously on the upper and lower work roll and is guided in the respective other guide block.
An beiden Führungsblöcken können die Verschiebevorrichtung für die Axialver- Schiebung einschließlich der Arbeitswalzenverriegelungen angebracht sein.On both guide blocks, the axial displacement shifter may be mounted, including the work roll latches.
Der obere bewegliche Führungsblock oder beide beweglichen Führungsblöcke werden im Walzenständer geführt.The upper movable guide block or both movable guide blocks are guided in the roll stand.
Zudem kann eine negative Biegung der Arbeitswalzen dadurch realisiert werden, dass die Druckdeckel die Arbeitswalzenbaustückohren oder die Führungsblöcke die Arbeitswalzeneinbaustückansätze formschlüssig umklammern.In addition, a negative bending of the work rolls can be realized in that the pressure cover the work roll construction tail pipes or the guide blocks clasp the work roll mounting lugs form fit.
Durch die Erfindung wird die hohe Zuverlässigkeit der jetzigen Biege- und Aus- balancierungsvorrichtung-Konstruktion gepaart mit einer höheren Flexibilität in Bezug auf Vergrößerung des Walzspaltes.The invention combines the high reliability of the present flexure and balancer design with greater flexibility in terms of nip enlargement.
Ein weiterer Vorteil besteht darin, dass man erfindungsgemäß mit einer minimalen Anzahl der Biege- und Balancierzylinder für positive- und negative Biegung auskommt, durch die gleichzeitige Wirkung auf die untere und obere Arbeitswalze.Another advantage is that according to the invention with a minimum number of bending and balancing cylinder for positive and negative bending gets by the simultaneous effect on the lower and upper work roll.
Die Erfindung erlaubt einen größeren Stellbereich der Arbeitswalzenbiegung (positiv und negativ), die für besondere Prozessanforderungen z.B. den Ste- ckelprozeß - große Walzkraftschwankungen innerhalb eines Bandes / Stiches - erforderlich bzw. wünschenswert ist.The invention allows a larger range of work roll deflection (positive and negative) that is suitable for particular process requirements, e.g. The Ste- ckelprozess - large rolling force fluctuations within a band / stitch - required or desirable.
Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen näher erläutert werden.The invention will be explained in more detail with reference to the drawings.

Fig. 3 einen Vertikalschnitt ähnlich Figur 1 in einer abgewandelte AusführungFig. 3 is a vertical section similar to Figure 1 in a modified embodiment
Fig. 4 eine weitere AusbildungFig. 4 is a further embodiment
Im Fenster des Walzenständers 1 sind die Arbeitswalzeneinbaustücke 3 und 3' für die obere und untere Arbeitswalze 10 bzw. 10' angedeutet. Der erfindungsgemäß geteilte Führungsblock ist am Fenster befestigt, wobei der obere Führungsblock 2 beweglich und der untere Führungsblock 2' ebenfalls beweglich oder ortsfest angeordnet sein kann. Die Arbeitswalzeneinbaustücke 3 und 3' sind durch die Verschiebevorrichtung 6 und 6' in Achsrichtung der Arbeitswalzen verschiebbar.In the window of the roll stand 1, the work roll chocks 3 and 3 'for the upper and lower work rolls 10 and 10' are indicated. The guide block divided according to the invention is fastened to the window, the upper guide block 2 being movable and the lower guide block 2 'likewise being movable or stationary. The work roll chocks 3 and 3 'are displaceable by the displacement device 6 and 6' in the axial direction of the work rolls.
Vertikal erfolgt die Positionsveränderung durch den Biege- und Balancierzylinder 5.Vertically, the change in position takes place through the bending and balancing cylinder 5.
Dieser steht über Druckdeckel 4 bzw. 4' mit den Arbeitswalzeneinbaustücken - oder besser gesagt, mit den Ohren dieser - in Eingriff, wobei es für die Erfindung auch wesentlich ist, dass durch nur einen Biege- und Balancierzylinder 5 die Verbindung zu dem oberen Arbeitswalzeneinbaustück 3 und dem unteren Arbeitswalzeneinbaustück 3' gleichzeitig hergestellt wird.This is about pressure cover 4 and 4 'with the work roll chocks - or rather, with the ears of these - in engagement, and it is also essential for the invention that by only one bending and Balancierzylinder 5, the connection to the upper work roll chock 3 and the lower work roll chock 3 'is simultaneously produced.
Bei der Ausführung nach Figur 3 ist - in Abwandlung von der Ausführung nach Figur 1 - lediglich die Kolbenanordnung getauscht.In the embodiment of Figure 3 is - in a modification of the embodiment of Figure 1 - only the piston assembly replaced.
Eine negative oder positive Anstellung der Arbeitswalzeneinbaustücke wird mit der Ausführung erreicht, die in der Figur 4 dargestellt ist. Hierbei umklammert der Führungsblock 2 den Ansatz des Arbeitswalzenein- baustücks 3 oder Druckdeckelerweiterungen 7 umklammern die Ohren der Ar- beitswalzeneinbaustücke 3 bzw. 3', so dass die Bewegung des Biege- und Balancierzylinders in beiden Richtungen direkt übertragbar ist. A negative or positive setting of the work roll chocks is achieved with the embodiment shown in FIG. Here, the guide block 2 clasps the approach of the work roll chock 3 or pressure cover extensions 7 clasp the ears of the work roll chocks 3 and 3 ', so that the movement of the bending and Balancierzylinder is directly transferable in both directions.
