Description

Die Erfindung betrifft in Ständerfenstern von Warmwalzgerüsten angeordnete Blöcke mit als Biegevorrichtung vorgesehenen hydraulischen Kolbenzylindereinheiten, die über Führungsstücke auf die Einbaustücke der Arbeitswalzen Biegekräfte zu übertragen vermögen.The invention relates to stator windows of hot rolling stands Blocks with hydraulic piston-cylinder units provided as a bending device, the guide pieces on the chocks of the work rolls Are able to transmit bending forces.

Es hat sich insbesondere bei Kaltwalzgerüsten bewährt, Biegevorrichtungen für die Arbeitswalzen in Blöcken anzuordnen, die vorzugsweise bereichsweise in Ausnehmungen der Ständerholme untergebracht sind. Schwierigkeiten ergaben sich bei der Konstruktion, da von den Biegevorrichtungen sowohl positive als auch negative Kräfte gewünscht werden, und da außerdem eine relative Verschiebbarkeit der Arbeitswalzen in Axialrichtung gegeneinander verlangt wird. Kritisch ist hierbei noch der Platzbedarf der Biegevorrichtungen, der die Möglichkeiten der Lagerung der Stützwalzen einschränkt.It has proven particularly useful in cold rolling stands, bending devices for arrange the work rolls in blocks, preferably in sections Recesses of the uprights are housed. Difficulties arose in the design because of the bending devices both positive and negative forces are also desired, and there is also a relative displaceability the work rolls are requested against each other in the axial direction. The space requirements of the bending devices and the possibilities are also critical here the storage of the backup rollers.

Die DE 195 36 042 A1 offenbart eine Führungsvorrichtung für Vier- oder Mehrwalzen- Kaltwalzgerüste, die mit einem Biegezylinder auf jeder Seite der Einbaustücke auskommt. Eine axiale Verschiebung der Walzen wird dadurch gewährleistet, daß die Biegeblöcke in ständerfensterfesten Axialführungen verschiebbar angeordnet sind. Durch diese Führungen werden die Ständerfenster stark eingeschnürt.DE 195 36 042 A1 discloses a guide device for four- or multi-roll Cold rolling stands, with a bending cylinder on each side of the chocks gets along. Axial displacement of the rollers is ensured that the bending blocks can be moved in the window guides fixed axial guides are arranged. Through these guides, the stand window severely constricted.

Die JP-A-59-153505 offenbart eine Führungsvorrichtung für die Arbeitswalzen eines Kaltwalzgerüstes, bei dem ein Biegezylinder auf jeder Seite der Einbaustücke vorgesehen ist. Diese Biegezylinder arbeiten auf verschwenkbare Führungsstücke, wodurch die Biegeblöcke sehr stark aufbauen, so dass die Ständerfenster entsprechend stark eingeschnürt werden bzw. entsprechend große Ständerfenster mit den dadurch verbundenen erheblichen Kosten Anwendung finden.JP-A-59-153505 discloses a guide device for the work rolls of a cold rolling mill with a bending cylinder on each side of the chocks is provided. These bending cylinders work on swiveling Guide pieces, which build the bending blocks very strong, so that the Stand windows are constricted accordingly or accordingly large stand windows with the associated considerable application costs Find.

Eine Übertragung der für Kaltwalzgerüste gefundenen Lösungen auf Warmwalzwerke ist daher praktisch unmöglich, da die hier zu entwickelnden Maximalkräfte die beim Kaltwalzen erforderlichen um mehr als den Faktor 3 überschreiten. Insbesondere zeigt es sich, daß die aufzubringenden Kräfte bei den in Frage kommenden Betriebsdrucken nicht mehr von jeweils einer hydraulischen Kolbenzylindereinheit vertretbarer Größe entwickelt werden können; für Warmwalzgerüste hat man daher die Biegevorrichtungen aufweisenden Blöcke kompliziert aufgebaut und mit einer Anzahl von bspw. sechs bis zwölf parallel arbeitenden Kolbenzylindereinheiten d. h. bis zu 24 Kolben-Zylindereinheiten pro Gerüst versehen. Weiterhin wurde als störend empfunden, daß die Biegevorrichtungen so große Abmessungen erfordern, daß eine freie Gestaltung der Lagerung der Stützwalzen nicht mehr möglich ist und bspw. auf Morgoil-Lager verzichtet werden muß und Wälzlager einzusetzen sind. A transfer of the solutions found for cold rolling stands to hot rolling mills is therefore practically impossible since the maximum forces to be developed here exceed those required for cold rolling by more than a factor of 3. In particular, it shows that the forces to be applied to the possible operating pressures no longer of one hydraulic Piston cylinder unit of reasonable size can be developed; For Hot rolling stands therefore have the blocks having bending devices complicated structure and with a number of, for example, six to twelve in parallel working piston cylinder units d. H. up to 24 piston-cylinder units provided per scaffold. It was also found to be disruptive that the bending devices such large dimensions require that the Storage of the backup rolls is no longer possible and, for example, on Morgoil bearings must be dispensed with and roller bearings must be used.

Die Erfindung geht daher von der Aufgabe aus, Arbeitswalzen-Biegevorrichtungen der oben bezeichneten Gattung zu schaffen, die die aufzubringenden Stellkräfte mit einer Kolbenzylindereinheit zu bewirken vermögen, und deren Abmessungen so gering sind, daß eine einfache Unterbringung in im Ständerfenster vorzusehenden Blöcken ermöglicht ist und die freie Wahl der Lager der Stützwalzen gesichert bleibt.The invention is therefore based on the object, work roll bending devices to create the genus described above, which the be applied Are able to effect actuating forces with a piston-cylinder unit, and whose dimensions are so small that easy accommodation in the Stand window blocks to be provided and the free choice of Bearing of the backup rollers remains secured.

Gelöst wird diese Aufgabe mit den Merkmalen des Patentanspruches. Sie gestatten den Aufbau von Biegevorrichtungen, die das Ständerfenster nur mäßig einschnüren und damit sowohl für die Einbaustücke der Stützwalzen als auch deren Lager ausreichend Raum bieten.This object is achieved with the features of the patent claim. Allow you the construction of bending devices, which the stand window only moderately constrict and thus both for the chocks of the backup rollers as well whose warehouses offer enough space.

Die wesentlichen Bestandteile dieser Biegevorrichtung 2 sind in einem hohlzylindrischen Gehause 3 angeordnet. Ein vertikal verschiebbarer Druckzylinder 4 enthält in seinem oberen, erweiterten, und im Gehäuse 3 geführten Bereich einen Kolben 5, dessen Kolbenstange 6 im unteren, auch mit geringerem Außendurchmesser ausgeführten Bereich des Druckzylinders 4 in einer Stempelhülse 7 geführt ist, die ihrerseits wiederum durch Schleißflächen 8 des Gehäuses 3 geführt ist. Die Kolbenstange 6 durchgreift einen Flansch der Stempelhülse 7 und stützt sich auf diesen mittels eines Druckringes 9 ab, während die mit einer Endplatte 10 gehaltene Endbuchse 11 Zugkräfte der Kolbenstange 6 zu übertragen vermag. Die Endplatte 10 ist mit einer seitlichen, in eine Ausnehmung der Stempelhülse 7 eingreifenden Nase versehen, die zusammen mit einem mit ihr verbundenen Bolzen als Verdrehsicherung für Kolben 5 und Kolbenstange 6 dient.In the figure, a spar 1 of a stand of a hot rolling stand has broken off shown, with a bending device shown as a vertical section 2 is provided. The essential components of this bending device 2 are in a hollow cylindrical housing 3 is arranged. A vertically movable Printing cylinder 4 contains in its upper, expanded, and guided in the housing 3 Area a piston 5, the piston rod 6 in the lower, also with smaller outer diameter executed area of the pressure cylinder 4 in a stamp sleeve 7 is guided, which in turn through wear surfaces 8th of the housing 3 is guided. The piston rod 6 passes through a flange Stamp sleeve 7 and is supported on this by means of a pressure ring 9, while the end sleeve 11 held with an end plate 10 tensile forces of the piston rod 6 is able to transfer. The end plate 10 is with a lateral one Provide recess of the stamp sleeve 7 engaging nose, which together with a bolt connected to it as an anti-rotation device for pistons 5 and Piston rod 6 is used.

Mit der Stirnseite des Druckzylinders 4 sowie der unteren Front der Stempelhülse 7 sind jeweils ein Führungsstück 12 bzw. 13 verbunden und nach hinten im Ständerfenster durch vertikale Schleißplatten 14, 15 abgestützt und ausgerichtet.With the front of the printing cylinder 4 and the lower front of the stamp sleeve 7 are each a guide piece 12 and 13 connected and in the rear Stand window supported and aligned by vertical wear plates 14, 15.

Die Arbeitswalzen 16, 17 des als Quartogerüst ausgeführten Warmwalzgerüstes sind mit nicht dargestellten Lagern in den Einbaustücken 18, 19 gelagert. Diese Einbaustücke sind mit seitlich auskragenden Nasen 20, 21 ausgestattet, die in Nute 22, 23 der Führungsstücke 12, 13 eingreifen und über Druckplatten 24 sich gegen deren Flanken abstützen. Die Nase 21 ist mit einer weiteren Druckplatte 25 ausgestattet, auf welcher der komplette Arbeitswalzensatz zum Wechseln ausfahrbar ist.The work rolls 16, 17 of the hot rolling stand designed as a four-high stand are stored in the chocks 18, 19 with bearings, not shown. These chocks are equipped with laterally projecting lugs 20, 21, which engage in grooves 22, 23 of the guide pieces 12, 13 and via pressure plates 24 support themselves against their flanks. The nose 21 is with another Pressure plate 25 equipped, on which the complete set of work rolls Switch is extendable.

Im Betriebe ergibt sich damit die folgende Funktion:
Die Nase 20 des Einbaustückes 18 hält über seine sich auf die Flanken der Nut 22 abstützenden Druckplatten 24 das Führungsstück 12 in einer der der Arbeitswalze 16 zugeordneten Höhe, während die Lage der Arbeitswalze 17 über die Nase 21 und deren sich auf die Flanken der Nut 23 abstützenden Druckplatten 24 die Höhe des Führungsstückes 13 bestimmt. Mit dem Führungsstück 13 sind die Stempelhülse 7 und die Kolbenstange 6 des Kolbens 5 verbunden, während das Führungsstück 12 mit dem Druckzylinder 4 verschraubt ist. Das bedeutet, daß durch die Stellung der Einbaustücke 18 und 19 auch die Lage des Kolbens 5 im Druckzylinder 4 bestimmt wird. Entsprechend der angewandten Regelung werden nun die obere und/oder die untere der im Druckzylinder 4 gebildeten Zylinderkammern unter Druck gesetzt und damit die Flächen des doppelt wirkenden Kolbens 5 entsprechend beaufschlagt. Die hierdurch an den Kolbenflächen entwickelten Kräfte werden den durch die Führungsflächen des Druckzylinders 4 sowie der Stempelhülse 7 im Gehäuse 3 vertikal verschiebbaren Führungsstücken 12, 13 zugeführt und beanspruchen über die Nasen 20, 21 die Einbaustücke 18, 19 mit der erforderlichen Vorspannung.This results in the following function in the company:
The lug 20 of the chock 18 holds the guide piece 12 at a height assigned to the work roll 16 via its pressure plates 24 which are supported on the flanks of the groove 22, while the position of the work roll 17 over the lug 21 and the flanks of the groove 23 supporting pressure plates 24 determines the height of the guide piece 13. The punch sleeve 7 and the piston rod 6 of the piston 5 are connected to the guide piece 13, while the guide piece 12 is screwed to the pressure cylinder 4. This means that the position of the piston 5 in the pressure cylinder 4 is determined by the position of the chocks 18 and 19. According to the applied control, the upper and / or the lower of the cylinder chambers formed in the pressure cylinder 4 are now pressurized and the surfaces of the double-acting piston 5 are accordingly acted upon. The forces thus developed on the piston surfaces are supplied to the guide pieces 12, 13 which can be displaced vertically by the guide surfaces of the pressure cylinder 4 and the stamp sleeve 7 in the housing 3 and, via the lugs 20, 21, stress the chocks 18, 19 with the required pretension.

Zum Walzenwechsel werden die Arbeitswalzen 16, 17 durch die Hubschiene 28 angehoben, wobei sich das untere Einbaustück 19 mit seiner an der Nase 21 vorgesehenen Druckplatte 25 auf der Hubschiene 28 abstützt.To change the rolls, the work rolls 16, 17 are moved by the lifting rail 28 raised, the lower chock 19 with its on the nose 21st provided pressure plate 25 is supported on the lifting rail 28.
