Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur regelbaren Beeinflussung der Reibkräfte zwischen den Führungsflächen und Anlageflächen von, in den Ständerfenstern 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 Blechbändern in Mehrwalzengerüsten, insb. bei höheren Walzgeschwindigkeiten, auftreten, die die Gefahr des Auftretens von Schwin gungsproblemen mit sich bringen. Diese Vibrationen können zu Oberflächenschä den, wie sog. "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 that often when rolling sheet metal strips in multi-roll stands, especially with higher ones Rolling speeds, which occur the risk of occurrence of Schwin bring problems with it. These vibrations can lead to surface damage the, like so-called "chatter marks" on the tapes and also have a negative effect the service life of the rollers. If using to avoid these vibrations must be rolled at lower rolling speeds, the productivity of the Rolling mill resulting in 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 Ständer fenster der Walzgerüste eingebaut und beaufschlagen die Andruckflächen der La gereinbaustücke. Diese Hohlkörper führen zwar zu einer Erhöhung der Reibkräfte zwischen den Führungs- und Anlageflächen von Ständerfenstern und Lagerein baustücken, weisen aber den Nachteil auf, daß sie die Anlagefläche der Lagerein baustücke nur ballig und nicht gleichmäßig ganzflächig beaufschlagen. Eine Ver änderung der Andruckstärken läßt sich nicht oder nur sehr schwierig herbeiführen. Eine definierte Anpreß- und Reibkraft läßt sich nicht, oder nur sehr schwierig her beiführen.It has already been suggested to address these vibration problems through generation a frictional force between the guide and contact surfaces of and counter bearing chocks with hollow bodies, which by means of hydraulic Were expandable. These expandable hollow bodies are in the stand windows of the roll stands and act on the pressure surfaces of the La chocks. These hollow bodies lead to an increase in the frictional forces between the guide and contact surfaces of the stand windows and the warehouse construction pieces, but have the disadvantage that they are the bearing surface of the bearing Only apply construction parts spherically and not evenly over the entire surface. A ver It is difficult or impossible to change the contact pressure. A defined contact and friction force can not, or only very difficult add.
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 Reib kräfte, 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 enable forces regardless of the respective rolling technology conditions.
Diese Aufgabe wird durch in den Ständerfenstern angeordnete, in diesen senk recht zu den Führungs- bzw. Anlageflächen von Ständerfenster und Lagerein baustück 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 arranged by lowering them into the stand windows right to the guide or contact surfaces of the stud window and warehouse Slidably guided construction piece, supporting the guide surfaces, flat, on the back 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 Lage reinbaustücken im Ständerfenster des Walzgerüstes unter Überbrückung des Be triebsspiels 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 layer Reinbaustücke in the stand window of the rolling mill by bridging the Be generate driving game, d. H. defined contact forces and friction forces independently specified by the rolling technology conditions.
Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbei spiels näher erläutert.The invention is based on the embodiment shown in the drawing explained in more detail.

Das Lagerein baustück 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 vorgese hen, in die, senkrecht zur Führungsfläche FF1, verschiebbar geführt, eine ebene Platte PL eingesetzt ist. Diese weist auf ihrer, dem Lagereinbaustück LE und des sen Anlagefläche AF zugewandten Seite die dieser zugeordnete Führungsfläche FF1 auf und wird rückseitig vom Kolben eines, in den Ständerholm SH eingesetz ten Kolben-Zylinder-Aggregats KZA beaufschlagt. Auf die, der Anlagefläche AF des Lagereinbaustücks LE zugewandte Fläche der Platte PL kann, auf nicht dar gestellte 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 warehouse Building element 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 hen, in which, perpendicular to the guide surface FF1, slidably guided, a level Plate PL is inserted. This shows on their, the bearing chock LE and the sen contact surface AF facing this associated guide surface FF1 open and is inserted on the back of the piston one, into the upright SH piston-cylinder unit KZA. On the, the AF contact surface of the bearing insert LE facing surface of the plate PL can not, on asked way a wear plate are put on, one side then forms the guide surface FF1.
