Abstract
Description
Die Erfindung bezieht sich auf einen Biegeblock zum Biegen der Walzen von Mehrwalzen-Walzgerüsten, der beidseitig der Lagereinbaustücke des zu biegenden Walzenpaares fest mit den Fensterholmen des Walzenständers oder mit Einrichtungen zur Horizontalstabilisierung der Walzen verbunden, in beiden Biegerichtungen verschiebbar geführte, über Kolbenzylinderaggregate antreibbare Biegebacken aufweist, die mit Druckauflageflächen der einen bzw. der anderen Biegerichtung zugeordnete Druckaufnahmeflächen an den Lagereinbaustücken bzw. den Einrichtungen beaufschlagen.The invention relates to a bending block for bending the rolls of multi-roll stands, which on both sides of the bearing chocks of the pair of rolls to be bent firmly connected to the window pillars of the roll stand or with devices for horizontal stabilization of the rolls, in both bending directions guided slidably, driven by piston-cylinder units bending jaws , which act on the bearing chocks or the devices with pressure bearing surfaces assigned to one or the other bending direction.
Bei den bekannten Ausbildungsformen (siehe z.B. DE-A 2250953) dieser Biegeblöcke an Mehrwalzengerüsten mit Paaren von Arbeitswalzen und diese beaufschlagenden Stützwalzen sind die Biegeblöcke vertikal geführt und weisen horizontale Schlitze mit Rechteckquerschnitt auf, die auf entsprechend geformte, an den Lagereinbaustücken der Arbeitswalzen vorgesehene rechteckförmige Anschlagnasen aufschiebbar sind. Bei Betätigung der, die Biegeblöcke antreibenden Kolbenzylinderaggregate werden damit die Biegekräfte auf die Lagereinbaustücke aufgebracht und deren Biegebewegung in Richtung aufeinanderzu bzw. voneinanderweg herbeigeführt. Die, den jeweiligen oberen bzw. unteren Lagereinbaustücken zugeordneten Biegebacken folgen während des Walzbetriebes dabei gemeinsam den, über die Balanciereinrichtungen der Stützwalzen auf die Arbeitswalzen aufgebrachten Vertikalbewegungen dieser Walzen.In the known forms of training (see, for example, DE-A 2250953) of these bending blocks on multi-roll stands with pairs of work rolls and supporting rolls which act on them, the bending blocks are guided vertically and have horizontal slots with a rectangular cross section, which have correspondingly shaped rectangular stop noses provided on the bearing chocks of the work rolls are postponed. When the piston cylinder units driving the bending blocks are actuated, the bending forces are thus applied to the bearing chocks and their bending movement in the direction toward or away from one another is brought about. The bending jaws assigned to the respective upper or lower bearing chocks jointly follow the vertical movements of these rolls, which are applied to the work rolls via the balancing devices of the support rolls, during the rolling operation.
Das, zwischen den horizontalen Schlitzen und den in diese eingreifenden Anschlagnasen erforderliche und unvermeidbare Führungsspiel zwischen den Druckauflageflächen der Schlitze und den Druckaufnahmeflächen der Anschlagnasen beeinträchtigt die genaue Einstellung der Biegekräfte insbesondere dann, wenn sehr kleine Biegekräfte aufgebracht werden sollen und auch bei Richtungswechseln der aufgebrachten Biegekräfte schlechthin (Nulldurchgang).The necessary and unavoidable guiding play between the pressure bearing surfaces of the slots and the pressure receiving surfaces of the stop lugs, which is necessary and unavoidable between the horizontal slots and the engaging stop lugs, affects the precise setting of the bending forces especially when very small bending forces are to be applied and also when the applied bending forces change direction (Zero crossing).
Der Erfindung liegt die Aufgabe zugrunde, diese Beeinträchtigungen zu beseitigen und die Möglichkeit eines, praktisch spielfreien Zusammenwirkens der Biegebacken mit den Lagereinbaustücken zu schaffen.The invention has for its object to eliminate these drawbacks and to create the possibility of a virtually play-free interaction of the bending jaws with the bearing chocks.
Diese Aufgabe wird dadurch gelöst, daß jede Biegebacke aus einem Paar von, selbständig, gegenläufig antreibbaren Teil-Biegebacken besteht, deren Druckauflageflächen jeweils der einen bzw. der anderen Biegerichtung zugeordnet sind.This object is achieved in that each bending jaw consists of a pair of independent, oppositely drivable partial bending jaws, the pressure bearing surfaces of which are assigned to one or the other bending direction.
Mit diesen selbständig und gegenläufig antreibbaren Paaren von Teil-Biegebacken werden jeweils Nuten gebildet, deren beide Druckauflageflächen gegeneinander druckverschiebbar sind, und die es deshalb erlauben, die Druckaufnahmeflächen der Anschlagnasen des jeweiligen Lagereinbaustücks beidseitig zangenartig mit Gegendruck zu erfassen und die Biegekräfte auch bei Richtungswechsel dieser Kräfte spielfrei auf die Lagereinbaustücke aufzubringen.With these independently and oppositely drivable pairs of partial bending jaws, grooves are formed in each case, the two pressure bearing surfaces of which can be pressure-shifted relative to one another, and which therefore make it possible to grasp the pressure receiving surfaces of the stop lugs of the respective bearing chock with pliers-like pressure on both sides and the bending forces even when these forces change direction apply to the bearing chocks without play.
Die Erfindung ist bei allen Ausbildungsformen von Zwei- und Mehrwalzen-Walzgerüsten anwendbar auch bei solchen mit axial verschiebbaren Walzen.The invention is applicable to all forms of training of two and multi-roll stands, including those with axially displaceable rolls.
Wie die Erfindung weiter vorsieht, kann die eine Teil-Biegebacke ein kubus- oder quaderförmiges Gehäuse aufweisen, das mit ebenen Anlagegleitflächen zwischen Gegenanlagegleitflächen des Gehäuses der anderen Teil-Biegebacke geführt ist. Das Gehäuse der anderen Teil-Biegebacke kann dabei aus zwei, mit Abstand voneinander angeordneten, das Gehäuse der einen Teil-Biegebacke zwischen sich führenden, durch eine Traverse miteinander verbundenen Gehäuseabschnitten bestehen. Weiter können die, die einander entsprechenden Teil-Biegebacken für die obere bzw. die untere Walze des zu biegenden Walzenpaares antreibenden Kolbenzylinderaggregates je aus einem Kolbenzylinderaggregat in der einen Teil-Biegebacke und Verbindungsstangen zu der jeweils anderen Teil-Biegebacke bestehen.As the invention further provides, the one partial bending jaw can have a cube-shaped or cuboid-shaped housing that is guided with flat contact sliding surfaces between counter-contact sliding surfaces of the housing of the other partial bending jaw. The housing of the others Part-bending jaw can consist of two spaced-apart, the housing of one part-bending jaw leading between them, connected to each other by a cross member housing sections. Furthermore, the piston cylinder unit which drives the corresponding partial bending jaws for the upper or lower roller of the pair of rollers to be bent can each consist of a piston cylinder unit in one partial bending jaw and connecting rods to the other partial bending jaw.

Wie aus Figur 1 zu ersehen, sind in den Fensterholmen 1 und 2 des Walzgerüstes, beiderseits der von den Stützwalzen 3 und 4 beaufschlagten Arbeitswalzenpaares 5, 6 die Biegeblöcke 7 und 8, fest mit den Fensterholmen 1 bzw. 2 verbunden, angeordnet. In den Biegeblöcken 7 bzw. 8 sind vertikal übereinander Paare von Teil-Biegebacken 11a, 11b bzw. 12a, 12b und 13a, 13b bzw. 14a, 14b vertikal geführt (vgl. hierzu auch Figuren 2, 3, 4 und 5).As can be seen from FIG. 1, the
Die dem oberen Lagereinbaustück 9 zugeordneten Teil-Biegebacken 13a, 13b eines Teil-Biegebackenpaares sind mit den darunter angeordneten, dem Lagereinbaustück 10 zugeordneten Teil-Biegebacken 14a, 14b (vgl. Figuren 4 und 5) gekoppelt und sind Zylindergehäuse von Kolbenzylinderaggregaten, deren Kolben 16 bzw. 19 durch gemeinsame Verbindungsstangen 17 bzw. 20 miteinander gekoppelt sind (vgl. Figur 4). Beim dargestellten Ausführungsbeispiel sind die Gehäuse der Teil-Biegebacken 13a, 13b (vgl. Figur 5) kubusförmig ausgebildet, wobei das Gehäuse der Teil-Biegebacke 13a aus zwei mit Abstand voneinander angeordneten Gehäusen besteht, zwischen denen das Gehäuse der anderen Teil-Biegebacke 13b gleitbar geführt ist (vgl. Figur 3). Die beiden Gehäuse der Teil-Biegebacke 13a sind dabei durch eine Traverse 21 ggfs. einstückig verbunden.The
An den jeweiligen Teil-Biegebacken sind, den Lagereinbaustücken 5, 6 zugewandte Anschlagleisten (Figur 1) 11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b angeordnet, die mit ihren Druckauflageflächen die Druckaufnahmeflächen von, an den Lagereinbaustücken 9 bzw. 10 angeordneten Anschlagnasen 9a, 9b bzw. 10a, 10b zu beaufschlagen vermögen, wenn die jeweiligen Teil-Biegebacken 11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b bei Betätigung der Kolben 16 bzw. 19 aufeinanderzu bewegt werden. Wie sich aus der Darstellung nach Figur 1 in Verbindung mit Figur 4 ergibt, bewegen sich dabei die Anschlagleiste 13a' der Teil-Biegebacke 13a und die Anschlagleiste 13b' der Teil-Biegebacke 13b in Richtung der in Figur 4 wiedergegebenen Pfeile aufeinanderzu und erfassen die ihnen zugeordnete Anschlagnase 9b des Lagereinbaustücks 9 zangenartig zwischen sich. Durch eine entsprechende hydraulische Steuerung der Kolben 16 und 19 kann jetzt der jeweils gewünschte Druck von oben oder von unten spielfrei auf die Anschlagnase 9b und damit auf das Lagereinbaustück 9 aufgebracht werden, ebenso entsprechend auf die übrigen Anschlagnasen 9a, 10a und 10b.On the respective partial bending jaws, the
Der Ausbau der Arbeitswalzen 5, 6 erfolgt durch deren Herausziehen aus separaten Führungen und über die Teil-Biegebacken (vgl. Fig. 1). Hier gleitet das untere Einbaustück 10 mit seinen Anschlagnasen 10a und 10 b auf den Anschlagleisten 12a' und 14a', und das obere Einbaustück 9 gleitet mit zusätzlichen Ausbaunasen 9a' und 9b' auf den Anschlagleisten 11a' und 13a'. Mit dieser Ausbildung wird erreicht, daß die Führungen für den Ausbau der oberen Arbeitswalze 5 in dem Raum vor und hinter dem Walzspalt für Bandführung, Kühl- und Spritzeinrichtungen nicht behindernd in Erscheinung treten. Die Arbeitswalzen 5, 6 können auch auf den Anschlagnasen 9a und 9b herausgezogen werden.The
Aus Fig. 2 ist ersichtlich, daß der Kolben 22 mit der Kolbenstange 23 zur Balancierung des Einbaustücks 24 der Stützwalze in dem Gehäuse des Biegeblocks 8 angeordnet ist.From Fig. 2 it can be seen that the
