Description

Die Erfindung betrifft eine Vorrichtung zur regelbaren Beeinflussung der Reibkräfte zwischen den Führungsflächen und Anlageflächen von, in den Ständerfenstem von Walzgerüsten geführten Lagereinbaustücken der Walzen.The invention relates to a device for controllably influencing the frictional forces between the guide surfaces and contact surfaces of, in the stand windows bearing chocks of the rollers guided by roll stands.

Vorrichtungen dieser Art dienen dazu, den Vibrationen entgegenzuwirken, die häufig beim Walzen von Blechbändem in Mehrwalzengerüsten, insb. bei höheren Walzgeschwindigkeiten, auftreten, die die Gefahr des Auftretens von Schwingungsproblemen mit sich bringen. Diese Vibrationen können zu Oberflächenschäden, wie sog.

Figure 00010001
Rattermarken" an den Bändern führen und wirken sich auch negativ auf die Standzeiten der Walzen aus. Wenn zur Vermeidung dieser Vibrationen mit kleineren Walzgeschwindigkeiten gewalzt werden muß, sinkt die Produktivität der Walzstraße mit der Folge des Entstehens höherer Kosten.Devices of this type serve to counteract the vibrations which frequently occur when rolling sheet metal strips in multi-roll stands, in particular at higher rolling speeds, which entail the risk of vibration problems occurring. These vibrations can cause surface damage such as so-called
Figure 00010001
Chatter marks "on the belts lead and also have a negative effect on the service life of the rolls. If rolling has to be carried out at lower rolling speeds in order to avoid these vibrations, the productivity of the rolling mill drops with the result of higher costs.

Es wurde bereits vorgeschlagen, diesen Schwingungsproblemen durch Erzeugung einer Reibkraft zwischen den Führungs- und Anlageflächen von Ständerfenster- und Lagereinbaustücken mit Hohlkörpern zu begegnen, die mittels hydraulischem Druck aufdehnbar waren. Diese aufdehnbaren Hohlkörper werden in die Ständerfenster der Walzgerüste eingebaut und beaufschlagen die Andruckflächen der Lagereinbaustücke. Diese Hohlkörper führen zwar zu einer Erhöhung der Reibkräfte zwischen den Führungs- und Anlageflächen von Ständerfenstern und Lagereinbaustücken, weisen aber den Nachteil auf, daß sie die Anlagefläche der Lagereinbaustücke nur ballig und nicht gleichmäßig ganzflächig beaufschlagen. Eine Veränderung der Andruckstärken läßt sich nicht oder nur sehr schwierig herbeiführen. Eine definierte Anpreß- und Reibkraft läßt sich nicht, oder nur sehr schwierig herbeiführen.It has already been suggested to address these vibration problems through generation a frictional force between the guide and contact surfaces of the stator window and To counter bearing chocks with hollow bodies, which by means of hydraulic Were expandable. These expandable hollow bodies are in the stand window of the rolling stands and act on the pressure surfaces of the bearing chocks. These hollow bodies lead to an increase in the frictional forces between the guide and contact surfaces of stand windows and bearing chocks, but have the disadvantage that they the contact surface of the bearing chocks only apply crowned and not evenly over the entire surface. A change the pressure strengths can not be achieved or only with great difficulty. A defined contact and friction force can not, or only very difficult to achieve.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäßen Vorrichtungen so zu verbessern, daß sie die ganzflächige Beaufschlagung der Andruckflächen der Lagereinbaustücke mit variablen Andruckkräften zur Erzeugung definierter Reibkräfte, unabhängig von den jeweiligen walztechnischen Bedingungen ermöglichen.The invention is based, so the generic devices the task to improve that they apply the entire area to the pressure surfaces of the Bearing chocks with variable pressure forces to generate defined friction forces, enable regardless of the respective rolling conditions.

Diese Aufgabe wird durch in den Ständerfenstern angeordnete, in diesen senkrecht zu den Führungs- bzw. Anlageflächen von Ständerfenster und Lagereinbaustück verschiebbar geführte, die Führungsflächen tragende, ebene, rückseitig druckbeaufschlagbare Trägerplatten gelöst. Wie die Erfindung weiter vorsieht, kann dabei ein, die Trägerplatte rückseitig beaufschlagendes, im Walzenständer angeordnetes Kolben-Zylinder-Aggregat vorgesehen werden. Schließlich kann auch die Möglichkeit vorgesehen werden, auf die Trägerplatten auswechselbare Verschleißplatten aufzusetzen, die die Anlagefläche aufweisen.This task is carried out vertically in the upright windows to the guide or contact surfaces of the stand window and bearing chock slidably guided, flat, on the back supporting the guide surfaces pressurizable carrier plates released. As the invention further provides can be one that acts on the back of the carrier plate in the roller stand arranged piston-cylinder unit are provided. Finally, can also the possibility to be provided, exchangeable on the carrier plates Put on wear plates that have the contact surface.

Die Vorrichtung erlaubt es, definierte Anpreßkräfte und Reibkräfte an den Lagereinbaustücken im Ständerfenster des Walzgerüstes unter Überbrückung des Betriebsspiels zu erzeugen, d.h. definierte Anpreßkräfte und Reibkräfte unabhängig von den walztechnologischen Bedingungen gezielt vorzugeben.The device allows defined contact forces and frictional forces on the bearing chocks in the stand window of the mill stand, bridging the operating game to generate, i.e. defined contact forces and friction forces independently specified by the rolling technology conditions.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is based on the embodiment shown in the drawing explained in more detail.

Die Zeichnung zeigt in schematischer Darstellung die Teilansicht eines in den Ständerholmen SH1, SH2 gebildeten Ständerfensters SF eines, im übrigen nicht dargestellten Walzgerüstes, gesehen in Walzenachsrichtung. Das Lagereinbaustück LE der Walze W ist im Ständerfenster SF zwischen den Führungsflächen FF1 und FF2 des Fensters in Richtung des Doppelpfeils DP auf- und abbewegbar geführt. In dem, in der Zeichnung links wiedergegebenen Ständerholm SH1 ist in der Begrenzungsfläche des Ständerfensters SF eine Ausnehmung AS vorgesehen, in die, senkrecht zur Führungsfläche FF1, verschiebbar geführt, eine ebene Platte PL eingesetzt ist. Diese weist auf ihrer, dem Lagereinbaustück LE und dessen Anlagefläche AF zugewandten Seite die dieser zugeordnete Führungsfläche FF1 auf und wird rückseitig vom Kolben eines, in den Ständerholm SH eingesetzten Kolben-Zylinder-Aggregats KZA beaufschlagt. Auf die, der Anlagefläche AF des Lagereinbaustücks LE zugewandte Fläche der Platte PL kann, auf nicht dargestellte Weise eine Verschleißplatte aufgesetzt werden, deren eine Seite dann die Führungsfläche FF1 bildet.The drawing shows a schematic representation of the partial view of one in the Stand spars SH1, SH2 formed stand window SF one, otherwise not Roll stand shown, seen in the roll axis direction. The bearing chock LE of the roller W is in the stand window SF between the guide surfaces FF1 and FF2 of the window can be moved up and down in the direction of the double arrow DP guided. In the stand beam SH1 shown on the left in the drawing is in the boundary surface of the stator window SF is provided with a recess AS, into which a plane is slidably guided perpendicular to the guide surface FF1 Plate PL is inserted. This points to their, the bearing chock LE and its Contact surface AF side facing this associated guide surface FF1 open and is inserted on the back of the piston of one into the upright SH Piston-cylinder unit KZA applied. On the, the AF contact surface of the bearing insert LE facing surface of the plate PL can, not shown Way a wear plate are placed, one side then forms the guide surface FF1.

Mit Hilfe des Kolben-Zylinder-Aggregates KZA läßt sich über, nicht dargestellte hydraulische Steuereinrichtungen die Platte PL in der Ausnehmung AS über den Anstellweg AW gegen das Lagereinbaustück LE verschieben. Dabei werden die vorerrechneten Anpreßkräfte FP und die, aus diesen resultierenden Reibkräfte FR zwischen den Führungsflächen FF1 und FF2 des Ständetfensters SF und den Andrückflächen AF1 und AF2 des Lagereinbaustücks LE erzeugt.With the help of the piston-cylinder unit KZA, not shown hydraulic control devices the plate PL in the recess AS over the Move the adjustment path AW against the bearing insert LE. The pre-calculated contact forces FP and the resulting friction forces FR between the guide surfaces FF1 and FF2 of the stand window SF and the pressure surfaces AF1 and AF2 of the bearing chock LE generated.

Die Platte PL läßt sich antriebsseitig oder bedienseitig bei Stützwalzen, Zwischenwalzen und auch Arbeitswalzen eines Walzgerüstes anwenden.The plate PL can be on the drive side or on the operator side for back-up rolls, intermediate rolls and also use work rolls of a roll stand.
