Description
Die Erfindung betrifft eine Walzvorrichtung mit zumindest zwei an einem gemeinsamen Gerüst angeordneten, an seitlichen Gerüstholmen in vertikal entlang den seitlichen Gerüstholmen beweglichen Lagerungen gehaltenen Walzen nach dem Oberbegriff des Anspruchs 1.The invention relates to a rolling device with at least two at a common Scaffolding arranged on side scaffold beams in vertically along Rolls held on the side girders of movable mounts according to the preamble of claim 1.
Derartige Walzvorrichtungen können ober- und unterseitig eines Walzspalts insbesondere jeweils mehrere einander abstützende Walzen enthalten, etwa eine Arbeitswalze, die direkt mit dem Walzgut in Kontakt kommt und ihrerseits auf einer zumeist größeren Stützwalze oder einer Zwischenwalze, die ihrerseits an einer Stützwalze anliegt, abrollt. Die Arbeitswalzen und/oder die Stützwalzen und/oder die Zwischenwalzen können dabei axial gegeneinander verschieblich sein. Bei einer Konturierung der Walzenballen mindestens zweier Walzen sind damit gezielte an dem den Walzspalt durchlaufenden Walzgut möglich. Die Höhe des Walzspalts soll dabei einstellbar sein, was eine vertikale Verlagerbarkeit der axialen Verschiebevorrichtung an dem Gerüst erfordert.Such rolling devices can on top and bottom of a roll gap in particular each contain a plurality of mutually supporting rollers, such as a work roll, which comes directly into contact with the rolling stock and in turn on a mostly larger support roll or an intermediate roll, in turn abuts on a support roller rolls. The work rolls and / or the backup rolls and / or the intermediate rollers can axially displaceable against each other be. In a contouring of the roll bale of at least two rollers thus targeted at the Walzspalt continuous rolling possible. The height the roll gap should be adjustable, which is a vertical displacement the axial displacement device on the framework requires.
insbesondere bei einer zusätzlich zur axialen Verschiebevorrichtung vorgesehenen Ausbildung einer Arbeitswalzenbiegevorrichtung ist es schwierig, auch bei einem großen Walzenaufgang, also bei einer großen Höhe des Walzspalts, diese Einstellbarkeit zu gewährleisten. Dieses beruht darauf, daß die in die Biegevorrichtung, mit der einem Auseinanderbiegen der den Spalt begrenzenden Walzen durch das Walzgut entgegengewirkt werden soll, integrierten Verriegelungselemente ebenso wie die Führungselemente für die axiale Verschiebevorrichtung und die Lagerungen für die Walzen in den seitlichen Holmen des Gerüsts verschoben und eingestellt werden müssen. Jedes dieser Elemente hat einen erheblichen Raumbedarf, so daß dann, wenn große Walzspalte realisierbar sind, ein kleiner Walzspalt nicht mehr einstellbar ist. in particular, provided in addition to the axial displacement device Training a work roll bender is difficult, too at a large roll rise, ie at a high height of the roll gap, to ensure this adjustability. This is due to the fact that in the bending device, with a bending apart of the gap bounding Rolling through the rolling stock to be counteracted, integrated locking elements as well as the guide elements for the axial displacement device and the bearings for the rollers in the lateral spars of the scaffolding have to be moved and adjusted. Each of these elements has a considerable space, so that when large roll gaps feasible are, a small nip is no longer adjustable.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Walzvorrichtung mit zumindest einer axialen Verschiebeeinrichtung zu schaffen, wobei die Walzvorrichtung, z.B. zum Walzen dicker Blöcke, bzw. Brammen, die Einstellung eines möglichst beliebig großen Walzenaufgangs möglich macht.The invention is therefore based on the object, a rolling device with at least an axial displacement device, wherein the rolling device, e.g. for rolling thick blocks, or slabs, setting a as large as possible roller tray makes possible.
Die Erfindung löst diese Aufgabe durch eine Walzvorrichtung mit den Merkmalen
des Anspruchs 1. Hinsichtlich vorteilhafter Ausgestaltungen wird auf die abhängigen
Ansprüche 2 bis 10 verwiesen.The invention solves this problem by a rolling device with the features
of claim 1. With regard to advantageous embodiments is based on the
Erfindungsgemäß ist mit der Integration der axialen Verschiebeeinrichtung in die die Lagerungen für eine Arbeitswalze aufnehmenden Bauteile eine erhebliche bauliche Vereinfachung erreicht, bei der die separate vertikale Verschiebbarkeit der axialen Verschiebevorrichtung nicht mehr erforderlich ist.According to the invention with the integration of the axial displacement device in the bearings for a work roll receiving components a considerable Structural simplification achieved in which the separate vertical displacement the axial displacement device is no longer required.
Wenn der die axiale Verschiebung bewirkende Kolben dabei außerhalb des Walzgerüsts gehalten ist, ist der Walzenwechsel erleichtert. Zudem sind die räumlichen Verhältnisse dann besonders günstig.If the piston causing the axial displacement outside of Roll stand is maintained, the roll change is facilitated. In addition, the spatial conditions then particularly favorable.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus einem in der Zeichnung dargestellten und nachfolgend beschriebenen Ausführungsbeispiel des Gegenstandes der Erfindung.Further advantages and features of the invention will become apparent from a in the Drawing illustrated and described below embodiment the subject of the invention.

Im Ausführungsbeispiel ist beispielhaft eine insgesamt mit 1 bezeichnete Walzvorrichtung
dargestellt, die als sogenanntes Vier-Walzen-Gerüst ausgebildet ist
und zwei Arbeitswalzen 2, 3 sowie zwei Stützwalzen 4, 5 umfaßt. Auch eine
andere Anzahl von Walzen ist möglich, beispielsweise auch die Ausbildung eines
Sechs-Walzen-Gerüsts mit zusätzlichen Zwischenwalzen zwischen den
Arbeitswalzen 2, 3 und den Stützwalzen 4, 5. Zwischen den Arbeitswalzen 2, 3
ist der Walzspalt 6 für das zu watzende Gut ausgehildet. Die Höhe 7 dieses
Walzspalts 6, der sogenannte Wafzenaufgang, ist einstellbar.In the exemplary embodiment is an example of a generally designated 1 rolling device
represented, which is designed as a so-called four-roller framework
and two
Die Walzen 2, 3, 4, 5 sind in einem Gerüst 8 gehalten, von dessen Ständern die
Holme 9 eines Ständers gezeigt sind, und die jeweils ein Fenster 10 begrenzen,
das als Führung für die vertikale Einstellbarkeit der Walzen 2, 3, 4, 5 und zur
Ermöglichung des Walzenwechsels dient.The
Zumindest eine der Arbeitswalzen 2, 3 - in der Regel mehrere der Walzen - ist
in Richtung ihrer axialen Erstreckung verschieblich. Hierfür ist eine Axial-Verschiebeeinrichtung
11 vorgesehen, die ein Antriebsmittel, etwa einen in
axialer Richtung der Walze 2, 3 orientierten und in Verlängerung dieser jeweiligen
Walze liegenden Kolben 12 umfaßt und die weiter unten noch näher beschrieben
ist.At least one of the
Die Stützwalzen 4, 5 sind über Stützwalzeneinbaustücke 13, 14 in den Randbereichen
der Fenster 10 an den Holmen 9 gehalten. Um die vertikale Verschieblichkeit
der Stützwalzen 4, 5 - zumindest der oberen Stützwalze 5 - sicherzustellen,
sind die Stützwalzeneinbaustücke 13, 14 in sich vertikal erstreckten
Gleitschienen 29 von seitlichen Haltevorrichtungen 27, 28, die an den Holmen 9
festgelegt sind, beweglich. Die Gleitschienen 29 sind zwischen den Holmen 9
und Vorsprüngen der Haltevorrichtungen 27, 28 ausgebildet und können mit
einem geeigneten Reibungsverminderer beschichtet sein. The back-up
Die im Ausführungsbeispiel gezeigten Arbeitswalzen 2, 3 sind in den Arbeitswalzeneinbaustücken
18, 19 über Lager 26 gelagert. Die Arbeitswalzeneinbaustücke
(18), 19 sind zumindest im Fall der oberhalb des Walzspalts 6 angeordneten
Arbeitswalze 3 in einer U-förmigen Ausnehmung 20 des oberen
Stützwalzeneinbaustücks 14 abgestützt (Fig. 2). Auch für die untere Arbeitswalze
2 kann eine derartige Lösung vorgesehen sein. Damit ist zumindest die obere
Arbeitswalze 3 mit der Stützwalze 5 vertikal mitbeweglich. Die Höheneinstellung
des Walzspalts 6 ist somit vereinfacht. Ebenso ist der Walzenwechsel vereinfacht.The
Innerhalb der Ausnehmung 20 ist auch die Biegevorrichtung 22 vertikal angeordnet.
Die Biegevorrichtung 22 kann alternativ aber auch, wie in Fig. 2 dargestellt,
in Aussparungen 31, 32 des jeweiligen Stützwalzeneinbaustücks 14 angeordnet
sein. Diese Biegevorrichtung 22 umfaßt wie auch die Biegevorrichtung
21 für die untere Arbeitswalze 2 jeweils den Lagerenden einer Arbeitswalze 2, 3
zugeordnete Druckelemente 23, die auf die äußeren Randbereiche der Arbeitswalzen
2, 3 nahe deren Lagerungen 26 einwirken und damit im Randbereich
der Walzen 2, 3 eine vertikal vom Walzspalt 6 auswärts gerichtete Kraft
entsprechend der im mittleren Bereich wirksamen Kraft des Walzguts ausüben,
um einem Auseinanderbiegen der Arbeitswalzen 2, 3 durch das Walzgut entgegenzuwirken.
Die Biegevorrichtung 22 wirkt somit zwischen dem Stützwalzeneinbaustück
14 einerseits und dem Arbeitswalzeneinbaustück 19 andererseits,
so daß eine separate Abstützung der Biegevorrichtung 22 an den Holmen
9 entbehrlich ist.Within the
Die oben erwähnten Axialverschiebeeinrichtungen 11 sind an den äußeren
Randbereichen der Arbeitswalzen 2, 3 angeordnet. Die axialen Verschiebeeinrichtungen
können an einer Seite oder, bei nicht angetriebenen Walzen, beidseits
einer Walze 2, 3 vorgesehen sein und umfassen im Ausführungsbeispiel
jeweils einen horizontal und in Verlängerung der Walzenachse angeordneten
und außenseitig der Holme 9 befindlichen Kolben 12. The above-mentioned
Alternativ sind auch mehrere, horizontal und parallel zur Walzenachse angeordnete
Kolben möglich. Der Kolben 12 der Axialverschiebeeinrichtung 11 ist
über ein Widerlager 25 an Haltearmen angeordnet, welche in den Arbeitswalzeneinbaustücken
18, 19 horizontal gleitend angeordnet sind. Die Haltearme 24
werden von seitlichen Haltevorrichtungen 16, 17 umgriffen, die an den Holmen
9 festgelegt sind und eine horizontale Bewegung der Haltearme 24 in Richtung
der Walzenachse verhindem. Damit ist auch der Kolben 12 der axialen Verschiebevorrichtung
11 in axialer Richtung fixiert. Die Haltearme 24 sind in den
Gleitschienen 15 der seitlichen Haltevorrichtungen 16, 17 in vertikaler Richtung
beweglich.Alternatively, several, horizontal and parallel to the roll axis arranged

Zylinergehäuse 30 über ein Widerlager 25 an Haltearmen 24 angeordnet und
über seitliche Haltevorrichtungen 16, 17 in axialer Richtung fixiert sind, ist möglich.
Die axiale Verschiebeeinrichtung 11 und das Lager 26 der Arbeitswalze 2,
3 sind somit gemeinsam in den Arbeitswalzeneinbaustücken 18, 19 integriert
und gemeinsam vertikal verschieblich. Eine separate vertikale Einstellungsmöglichkeit
