Abstract

A mounting for a roller in a rolling mill has a locking system with a locking ring with flats (FA) axially sprung to locate into fixed locking profiles (AS) on the fixed mounting and thereby locking the roller drive when the roller is removed. This ensures a simple removal and replacement of the roller, with an automatic locking action.

Description

Vorrichtung zur Drehverriegelung einer, in den Ständerfenstern von Walzgerüsten in Lagereinbaustücken lagernden WalzwerkswalzeDevice for the rotational locking of a rolling mill roll stored in bearing blocks in rolling mill stands in the stator windows
Die Erfindung betrifft eine Vorrichtung zur Drehverriegelung einer, in den Ständerfenstern von Walzgerüsten in Lagereinbaustücken lagernden Walzwerkswalze. Beim Auswechseln solcher Walzen verwendet man Schienenkonstruktionen, mit deren Hilfe die Walzen zusammen mit ihren Lagereinbaustücken durch die Ständerfenster des Walzgerüstes hindurch ein- und aus diesen herausgefahren werden. Diese Schienen und die für die Verfahrbewegungen notwendigen Antriebselemente nehmen vor dem Walzgerüst viel Raum in Anspruch und behindern dadurch das Einbringen und die Bewegung von Zusatzaggregaten für den Walzbetrieb.The invention relates to a device for the rotational locking of a, stored in the stator windows of rolling stands in bearing chocks rolling mill. When replacing such rolls used rail structures, with the help of the rollers along with their bearing chocks through the stator window of the rolling stand on and are driven out of these. These rails and necessary for the traversing movements drive elements take up a lot of space in front of the rolling mill and thereby hinder the introduction and movement of additional units for rolling operation.
Man hat deshalb schon vorgeschlagen, den Walzenwechsel mit einem Tragbalken, sog. Porterbar, vorzunehmen. Dabei wird ein Zapfen der Walze mit dem an einem Kran hängenden Porterbar verbunden, und die Walze in dieser Position aus dem Gerüst herausgefahren. Bei diesem Verfahren ergibt sich die Schwie- rigkeit, dass die Lagereinbaustücke sich während der Transportbewegungen um die Walzen drehen. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die die Lagereinbaustücke während des Ausbringens und des Transports bis zum Wiedereinbringen in das Walzgerüst zur walze hin drehverriegelt und anschließend, nachdem die Walze mit Walzeneinbaustücken in das Gerüst eingebracht worden ist, bei ihrem Anschluss an die Antriebseinrichtung z. B. bei Aufbringen des Treffers auf den Walzenzapfen diese Drehverriegelung außer Wirkung bringt. Diese Aufgabe wird durch ein auf den Zapfen der Walze aufgeschobenes zylindrisches Schiebegehäuse gelöst, das außenseitig ebene Flächenabschnitte aufweist, die in einer Schiebeposition an entsprechenden Flächenabschnitten von mit dem Lagereinbaustück verbundenen Anschlagelementen anliegen und damit das zylindrische Schiebegehäuse gegen das La- gereinbaustück drehverriegeln. Wie die Erfindung weiter vorsieht, kann das Schiebegehäuse als eine zylindrische Flanschringbüchse ausgebildet sein, deren Flanschringe außenseitig diese ebenen Flächenabschnitte aufweisen. Weitere Ausbildungsmerkmale der Erfindung sind in den Unteransprüchen niedergelegt.It has therefore been proposed to make the roll change with a support bar, so-called. Porterbar. In this case, a pin of the roller is connected to the hanging on a crane Porterbar, and moved out of the frame in this position, the roller. In this method, there is the difficulty that the bearing chocks rotate around the rollers during the transport movements. The invention has for its object to provide a device which rotatably locks the bearing chocks during dispensing and transport until reintroduced into the rolling mill to roll and then, after the roll has been introduced with roll chocks in the scaffold at their connection the drive device z. B. when applying the hit on the roll neck this twist lock brings out of action. This object is achieved by a pushed onto the pin of the roller cylindrical sliding housing having the outside flat surface portions which abut in a sliding position on corresponding surface portions of the bearing chock associated stop elements and thus the cylindrical sliding housing against the La lock the installation block. As the invention further provides, the sliding housing may be formed as a cylindrical flange ring bushing, the flange rings on the outside have these flat surface portions. Further training features of the invention are laid down in the subclaims.
Die Erfindung wird anhand der in der Zeichnung dargestellten Ausbildung der Vorrichtung näher erläutert.The invention will be explained in more detail with reference to the embodiment of the device shown in the drawing.
In der Zeichnung zeigen in schematischer Darstellung:In the drawing show in a schematic representation:
Figur 1 die Ansicht eines Radialschnitts durch Walzenzapfen und Schiebegehäuse, gesehen in Richtung auf das Lagereinbaustück;Figure 1 is a view of a radial section through roll neck and sliding housing, seen in the direction of the bearing chock;
Figur 2 die Seitenansicht eines Teilschnittes durch Figur 1 ;Figure 2 is a side view of a partial section through Figure 1;
Figur 3 die Ansicht eines anderen Radialschnitts entsprechend Fig. 1 ;Figure 3 is a view of another radial section corresponding to Fig. 1;
Figur 4 die Seitenansicht von Fig. 3 undFigure 4 shows the side view of Fig. 3 and
Figur 5 eine Einzelheit der Ansicht nach Fig. 3.FIG. 5 shows a detail of the view according to FIG. 3.
Wie aus den Figuren 1 und 2 zu ersehen, ist auf dem Walzenzapfen WZ eine axial verschiebbare Flanschringhülse FB angeordnet, deren Flanschring FR außenseitig ebene Flächenabschnitte FA aufweist. Auf dem Lagereinbaustück LS sind Anschläge AS mit Anlageflächen für die ebenen Flächenabschnitte FA des Flanschrings FR angeordnet. Wie in Fig. 2 dargestellt, sitzt auf dem Walzenzapfen WZ der Treffer TR des Walzenantriebs und die Unterseite des Flanschrings FR liegt auf im Lagereinbaustück LS angeordneten Stützfedern SF auf, die den Flanschring FR gegen die Stirnseite des Treffers TR drücken. In dieser Position befinden sich die ebenen Flächenabschnitte FA des Flanschrings FR außerhalb des Anschlags AS mit der Folge, dass der Walzenzapfen WZ mit dem Flanschring FR im Lagereinbaustück LS frei drehen kann. Wird, wie aus Fig. 4 zu ersehen ist, für den Transport der Walze der Walzenzapfen WZ vom Treffer TR freigegeben, dann drücken die Stützfedern SF im Lagereinbaustück LS den Flanschring in eine Position, bei der dessen Anlageflächen AF an dem Anschlag AS anliegen und damit den Flanschring FR auf dem Walzen- zapfen WZ drehblockieren. Diese Blockierung wird nach Einbringen der Walze mit den Lagereinbaustücken LS in das Walzgerüst durch den auf Walzenzapfen WZ aufgeschobenen Treffer TR aufgehoben, der den Flanschring FR wieder in die in Fig. 2 dargestellte Position schiebt. As can be seen from Figures 1 and 2, an axially displaceable flange ring sleeve FB is arranged on the roll neck WZ, the flange FR has outside flat surface portions FA. On the bearing block LS stops AS are arranged with contact surfaces for the flat surface portions FA of the flange FR. As shown in Fig. 2, sitting on the roll neck WZ the hit TR of the roll drive and the underside of the flange FR is located on the bearing chuck LS arranged support springs SF, which press the flange FR against the end face of the hit TR. In this position, the flat surface portions FA of the flange FR are outside of the stop AS, with the result that the roll neck The tool can rotate freely with the flange ring FR in the bearing chuck LS. Is, as can be seen from Fig. 4, released for the transport of the roll of the roll neck WZ from the hit TR, then press the support springs SF in the bearing chuck LS the flange in a position in which rest their contact surfaces AF on the stop AS and thus lock the flange ring FR on the roller journal WZ. This blocking is canceled after introducing the roller with the bearing chocks LS in the roll stand by the pushed onto roll neck WZ hit TR, which pushes the flange FR back into the position shown in Fig. 2.
