Abstract

The invention relates to a device for coupling and uncoupling fluid lines for bearing inserts in rollers running in roll stands, in particular for working rollers and support rollers. The above device is improved, whereby the coupling elements for the fluid lines are automatically coupled to and uncoupled from the fluid connectors in the bearing insert.

Description

Medienkupplung für WalzgerüsteMedia coupling for roll stands
Die Erfindung betrifft eine Vorrichtung zum Kuppeln und Entkuppeln der Medienzuleitungen an den in Walzenständern geführten Lagereinbaustucken von Walzen, insbesondere von Arbeitswalzen und Stützwalzen.The invention relates to a device for coupling and uncoupling the media feed lines on the bearing chocks of rollers guided in roller stands, in particular of work rollers and backup rollers.
Das Kuppeln und Entkuppeln der Medienzuleitungen ist besonders bei den Öl- flutlagern von Kaltwalzgerüsten mit Schwierigkeiten verbunden, weil sich die Kupplungsanschlüsse der Lagereinbaustücke durchweg auf der schwer zugänglichen Antriebsseite der Walzgerüste befinden. Um dennoch die Kupplungselemente sicher zu handhaben, insbesondere die relativ großen Kupplungselemente der Ölablaufleitungen wird eine große Erfahrung des Bedie- nungspersonals vorausgesetzt. Durch die Höhe der oberen Einbaustücke von Stützwalzen ist das Bedienungspersonal erheblich gefährdet. Auch die Schlaucheigenspannungen führen dazu, daß das manuelle Kuppeln und Entkuppeln der Medien an Walzgerüsten eine schwer durchzuführender und risikobehaftete Arbeit für das Bedienungspersonal bleibt.Coupling and uncoupling of the media supply lines is particularly difficult with the oil flood bearings of cold rolling stands, because the coupling connections of the bearing chocks are always on the hard-to-access drive side of the rolling stands. In order to handle the coupling elements safely, in particular the relatively large coupling elements of the oil drain lines, extensive experience of the operating personnel is required. Due to the height of the upper chocks of back-up rollers, the operating personnel is at considerable risk. The hose internal stresses also mean that the manual coupling and uncoupling of the media on roll stands remains a difficult and risky job for the operating personnel.
Aus dem Dokument EP 0 947 255 A2 ist eine Vorrichtung zum Kuppeln und Entkuppeln der Medienzuleitungen an den in Walzenständern geführten Lagereinbaustucken von Walzen bekannt. Die hierbei verwendeten Kupplungselemente der Medienzuleitungen sind den Medienanschlüssen in den Lagerein- baustücken zugewandt und sind gemeinsam in einem Träger angeordnet. Dieser Träger ist parallel zur Anstellbewegungsrichtung der Lagereinbaustücke in einem Führungsrahmen geführt. Der Führungsrahmen ist mit dem Walzenständer verbundenen Führungen in Walzenachsrichtung gegen das Lagereinbaustück und von diesem weg verschiebbar gehalten. Hierdurch wird das An- kuppeln und Endkuppeln der Medienzuleitung halbautomatisch durchführbar. Ausgehend von diesem Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, eine Vorrichtung für das automatische Kuppeln aller vier Einbaustük- ke eines Arbeitswalzensatzes bzw. eines Stützwalzensatzes mit allen notwendigen Ver- und Entsorgungsmedien bereitzustellen.From document EP 0 947 255 A2, a device for coupling and uncoupling the media feed lines on the bearing chocks of rolls guided in roll stands is known. The coupling elements of the media feed lines used here face the media connections in the bearing chocks and are arranged together in one carrier. This carrier is guided in a guide frame parallel to the direction of movement of the bearing chocks. The guide frame is connected to the roller stand and held in the roller axis direction against the bearing chock and away from it. As a result, the coupling and final coupling of the media supply line can be carried out semi-automatically. Based on this prior art, it is the object of the present invention to provide a device for the automatic coupling of all four chocks of a work roll set or a backup roll set with all the necessary supply and disposal media.
Die Aufgabe wird in erfinderischer Weise dadurch gelöst, daß alle vier Einbaustücke der Stützwalzen bei Quarto-Gerüsten bzw. der Arbeitswalzen bei Duo-Walzgerüsten mit einer automatisierten Ölrücklaufkupplung versehen sind für den Ölrücklauf, den Ölvorlauf, die Hydrostatik, die Hydraulik, Fettschmierung, Pneumatik oder dergleichen. Die Kupplung ist so ausgelegt, daß große Olmengen mit wenig Rücklaufwiderstand gefördert werden können. Auf der Einbaustückseite, d. h. in Bereichen der Medienanschlüsse werden die Kupplungen bei Entkupplung durch federbetätigte Klappen automatisch öldicht verschlossen.The object is achieved in an inventive manner in that all four chocks of the support rollers in four-high stands or the work rollers in duo-roll stands are provided with an automated oil return coupling for the oil return, the oil supply, the hydrostatics, the hydraulics, grease lubrication, pneumatics or like. The coupling is designed so that large quantities of oil can be pumped with little return resistance. On the back cover, d. H. In the areas of the media connections, the couplings are automatically sealed oil-tight when disconnected by spring-operated flaps.
Hierzu weist die Klappe einen Dichtkegel auf, der gegen einen Radialwellen- dichtring schließt. Die Klappenkonstruktion mit Dichtkegel ist in Figur 1 dargestellt. Figur 2 zeigt schematisch die An- bzw. Entkopplungssituation.For this purpose, the flap has a sealing cone that closes against a radial shaft sealing ring. The valve construction with sealing cone is shown in Figure 1. Figure 2 shows schematically the coupling or decoupling situation.
Das Ölrücklaufrohr ist ebenfalls mit einem Radialwellendichtring RWDR abge- dichtet, wie dies vergrößert in Figur 3 dargestellt ist.The oil return pipe is also sealed with an RWDR radial shaft sealing ring, as is shown enlarged in FIG. 3.
Die automatisch wirkende Kupplung hat alle Freiheitsgrade, die durch die Bewegung des Einbaustückes im Walzenständer verursacht sind infolgeThe automatically acting coupling has all degrees of freedom caused by the movement of the chock in the roll stand
- unterschiedlicher vertikaler Positionen durch Walzenabschliff und Wär- meausdehnung- Different vertical positions due to roll grinding and thermal expansion
- unterschiedlicher Winkellage des Einbaustücks infolge der Schrägstellung durch Walzenbiegung.- Different angular position of the chock due to the inclination due to roller bending.
Die automatisch arbeitende Medienkupplung für Walzeneinbaustücke ist so ausgelegt, daß durch sie auch das Verriegeln der Einbaustücke zum Walzenständer erfolgen kann. Die gekuppelte und entkuppelte Position der Kupplung wird beispielsweise durch eine elektrische Signalgebung überwacht und das elektrische Signal wird in die Prozeßautomatik eingebunden. The automatic media coupling for roller chocks is designed so that it can also be used to lock the chocks to the roller stand. The coupled and uncoupled position of the clutch is monitored, for example, by electrical signaling and the electrical signal is integrated into the automatic process.
