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.

Description
Die Erfindung betrifft eine Vorrichtung zum Angleichen der Oberkante der unteren Arbeitswalze von Walzgerüsten, insbesondere Quarto-Gerüsten an die Walzlinie mittels eines Keilpaares unterhalb jedes unteren Walzeneinbaustückes, bestehend aus einem unteren, horizontal in Walzenachsrichtung verschiebbarem Keilelement und einem oberen, ausschließlich in vertikaler Richtung verschiebbaem Keilelement, die während des Walzvorganges mit ihren Keilflächen aufeinanderliegen.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.
Es ist bekannt, daß Angleichen der Oberkante der Arbeitswalzen an die Walzlinie durch Passplatten unterschiedlicher Höhe vorzunehmen, welche nach dem jeweils erforderlichen Ausgleichsmaß ausgewählt werden. Diese Platten werden gemeinsam mit den Einbaustücken von einem Wagen ein- und ausgefahren. Diese Lösung ist nachteilig, weil für jedes Ausgleichsmaß zwei besondere Paßplatten erforderlich sind, von denen insbesondere die höheren schwer zu handhaben sind.It is known to adjust the upper edge of the work rolls to the rolling line by means of shims of different heights, which are selected according to the required compensation dimension. These plates are moved in and out of a car together with the chocks. This solution is disadvantageous because two special fitting plates are required for each compensation dimension, the higher ones in particular being difficult to handle.
Es ist weiterhin bekannt, die in einem Verschieberahmen aufgenommenen Paßstücke unterschiedlicher Höhe selektiv unter die Einbaustücke in die Ständerfenster eines Quarto-Gerüstes einzufahren. Dazu sind als Hubeinrichtung für die Einbaustücke in den Ständern Traversenzylinder angeordnet, die eine aufwendige Bearbeitung der Ständer erforderlich machen (DE-A-28 06 525).It is also known to selectively move the fitting pieces of different heights accommodated in a sliding frame under the chocks into the stand windows of a four-high scaffold. For this purpose, 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).
Durch das europäische Patent EP-B-02 31 445 ist eine Vorrichtung zur Höhenverlagerung von Walzen in Walzgerüsten bekannt geworden, bei der in gattungsgemäßer Weise unter jedem Einbaustück der Stützwalze ein Keilpaar angeordnet ist, mit dem ein stufenloser Höhenausgleich der Walze dadurch erreicht werden kann, daß der untere Keil in Horizontalrichtung verschiebbar und der obere Keil in Vertikalrichtung verschiebbar ist. Bei diesem Stand der Technik ist zwischen dem oberen Keil und der Unterseite des Stützwalzeneinbaustückes eines von mehreren unterschiedlich hohen Paßstücken eingesetzt, die in ihrer Höhe treppenartig gestuft nacheinander durch Querverschieben in die Arbeitsstellung verbringbar sind. Auf diese Weise kann bei der bekannten Vorrichtung ein stufenförmiger Ausgleich der Arbeitswalzenlage durch Einschieben der unterschiedlich hohen Pass-Stücke vorgenommen werden, während die Keilanordnung dazu dient, die Stufenhöhen zu überbrücken.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. In this prior art, 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. In this way, in the known device, 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.
Die bekannte Vorrichtung ist infolge der Nebeneinanderanordnung von verschiebbaren Paßstücken und Keilen sehr bauaufwendig und benötigt zudem ausreichenden Platz, um die verschieden gestuften Paßstücke unterzubringen.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.
Ausgehend von der letztgenannten europäischen Patentschrift liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung so zu vereinfachen, daß mit einfachen und vor allem platzsparenden Einrichtungen ein hinreichend genaues Angleichen der Oberkante der unteren Arbeitswalze an die Walzlinie vorgenommen werden kann.Based on the last-mentioned European patent specification, 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.
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß jedes obere Keilelement mittels einer Hubvorrichtung zusammen mit dem jeweiligen Walzeneinbaustück anheb- und absenkbar ist und daß die Keilflächen beider Keile treppenartig gestuft sind, wobei die Stufen ineinandergreifend die Keilelemente vertikal abstützen.To achieve the object, it is proposed according to the invention that 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.
Kern der vorliegenden Erfindung ist es, das obere Keilelement selbst einerseits mit dem Hubelement für das Einbaustück der anzuhebenden Walze zu verknüpfen und andererseits gleichzeitig zur Abstützung des Einbaustückes in der jeweils gewünschten Höhenlage zu verwenden. Durch das Anheben des oberen Keilelementes selbst wird es möglich, das untere Keilelement in die jeweils gewünschte Position zu verschieben und danach das obere Keilelement darauf abzusetzen. Damit eine Selbsthemmung der Keile möglich ist, sind die Keilflächen treppenförmig gestuft. Dadurch können die Keile sehr kurz bauen, wodurch der Verschiebeweg äußerst kurz gehalten werden kann. Dadurch wird eine äußerst einfache und auch robuste Vorrichtung geschaffen, die platzsparend in dem Walzgerüst unterzubringen ist.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.
In einer besonders günstigen Ausgestaltung ist vorgesehen, daß das obere Keilelement Teil einer das untere Keilelement übergreifenden Traverse ist, die mittels seitlich neben dem unteren Keilelement angeordneter Kolben-Zylinder-Einheiten heb- und senkbar ist, wobei das jeweilige Walzeneinbaustück auf der Traverse aufliegt und die Traverse in Vertikalrichtung geführt ist. Die vorgeschlagene Lösung ermöglicht die Anordnung der als Kolben-Zylinder-Einheiten ausgebildeten Hubvorrichtung außerhalb des Verschiebeweges der unteren Keilelemente. Die Kolben-Zylinder-Einheiten können beispielsweise seitlich an die Walzenständer angeflanscht werden. Darüber hinaus sind die Kolben-Zylinder-Einheiten gut sichtbar und somit leicht zu inspizieren. Das jeweilige Einbaustück liegt auf den Traversen auf, an deren Unterseite das obere Keilelement ausgebildet ist.In a particularly favorable embodiment, it is provided that 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. In addition, 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.
Nach einer Weiterbildung Merkmal der Erfindung wird vorgeschlagen, daß die Führung für die Traverse aus mindestens zwei Führungsbolzen besteht, die von entsprechenden senkrechten Bohrungen der Traverse umgriffen werden.According to a development feature of the invention, it is proposed that the guide for the traverse consists of at least two guide bolts which are encompassed by corresponding vertical bores in the traverse.
Letztere Führungen sind erforderlich, damit sichergestellt ist, daß das obere Keilelement ausschließlich in vertikaler Richtung und in diese Richtung frei bewegbar ist. Bolzen und Bohrungen sind sehr einfache Bauelemente, die den hier gestellten Anforderungen voll genügen.The latter guides are required to ensure that the upper wedge element can only be moved freely in the vertical direction and in this direction. Bolts and holes are very simple components that fully meet the requirements set here.
Es hat sich gezeigt, daß günstige Stützverhältnisse erzielt werden, wenn das Verhältnis der horizontalen zur vertikalen Erstreckung der Stufen etwa 2 : 1 bis 3 : 1 ist. Je nach Anforderungen an die Verstellbarkeit der Arbeitswalzen wird die Höhe und Zahl der Stufen gewählt werden, wobei grundsätzlich gilt, daß bei mehreren kleinen Stufen eine feinere Anpassung an die Höhenlage erfolgen kann, als bei wenigen hohen Stufen.It has been shown that favorable support ratios are achieved if the ratio of the horizontal to the vertical extent of the steps is approximately 2: 1 to 3: 1. Depending on the requirements for the adjustability of the work rolls, the height and number of steps will be selected, with the general rule that with several small steps a more precise adjustment to the altitude can be made than with a few high steps.

In Figur 1 ist mit 1 die untere Stützwalze des ansonsten nicht dargestellten Quarto-Walzgerüstes bezeichnet. Die Stützwalze ist beiderseits in Einbaustücken 2 und 3 gelagert, die ihrerseits im Walzenständer 4 heb- und senkbar geführt sind.In FIG. 1, 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
Die Vorrichtung besteht hauptsächlich aus den unteren Keilelementen 5 sowie den oberen Keilelementen 6, die in der rechten Figurenhälfte dargestellt, in der linken nur angedeutet sind. Beide Keilelemente 5, 6 sind mit kleinen Stufen versehen, die die sonst bei Keilen üblichen ebenen Keilflächen ersetzen. Diese Stufen sind an beiden Keilen 5, 6 gleichartig ausgebildet und passen gut ineinander so daß das obere Keilelement 6 sicher auf dem unteren Keilelement 5 aufliegt und große horizontale Kräfte aufnehmen kann.The device mainly consists of the lower wedge elements 5 and the
Wie bei 7 angedeutet, ist jedes untere Keilelement 5 mit Hilfe eines Antriebes in horizontaler Richtung parallel zur Achsrichtung der Stützwalze 1 verschiebbar, wobei beide unteren Keilelemente über Zugelemente 8 miteinander verbunden sind und somit im Gleichlauf bewegt werden.As indicated at 7, each lower wedge element 5 can be displaced in the horizontal direction parallel to the axial direction of the
Jedes obere Keilelement 6 ist an der Unterseite einer Traverse 9 ausgebildet, deren Form in Figur 2 in der Draufsicht deutlich erkennbar ist. Die Traversen 9 beider Seiten sind gleichartig dimensioniert und bestehen aus einem in der Draufsicht doppel-T-förmigen Körper, der das untere Keilelement 5 übergreift. An den äußeren Enden der Traverse 9 sind vier Kolben-Zylinder-Einheiten 10 angeordnet, mit denen die Traverse 9 und mit ihr das bei 11 auf ihr aufsitzende Einbaustücke 2 bzw. 3 anhebbar ist.Each
Bei angehobener Traverse können durch Querverschiebung mit Hilfe des Antriebs 7 die unteren Keilelemente unter die oberen Keilelemente 6 eingeschoben oder ausgefahren werden, so daß nach Absenken der Traverse mit den oberen Keilelementen 6 die Höhenlage der Stützwalze und der darüber angeordneten Arbeitswalze variiert werden kann.When the crossbar is raised, the lower wedge elements can be inserted or extended under the
Um zu verhindern, daß die Traversen mit den oberen Keilelementen 6 beim Verschieben der unteren Keilelemente 5 ihre Lage in Bezug auf Querrichtungen zu den Einbaustücken 2 und 3 verändern, sind Bolzen 12 vorgesehen, die sich auf dem unteren Gerüstrahmen 4 senkrecht erstrecken und entsprechende Bohrungen in den Traversen 9 durchdringen. Die Bolzen bzw. die Bohrungen gestatten ausschließlich eine Vertikalbewegung der Traverse und damit auch der oberen Keilelemente 6.In order to prevent the crossbeams with the
In Figur 3 ist die Anordnung der Kolben-Zylinder-Einheiten 10 in Bezug auf die Traverse erkennbar. Es ist deutlich zu sehen, daß die Kolben-Zylinder-Einheiten 10 den Bewegungsweg der unteren Keilelemente 5 nicht behindern, weil sie seitlich neben ihnen angeordnet sind.The arrangement of the piston-
Gleichzeitig ist aus Figur 3 erkennbar, daß seitlich neben der erfindungsgemäßen Vorrichtung Ausfahrschienen 13 für den Walzensatz angeordnet sind, auf denen - wie dargestellt - Radsätze abrollen, die an den unteren Einbaustücken der Stützwalze 1 vorgesehen sind.At the same time, it can be seen from FIG. 3 that
