Description

Die Erfindung betrifft eine Vorrichtung zur automatischen Positionierung von Walzgerüsten mit Kaliberwalzen und diesen vorgeordneten Walzbalken und Walzarmaturen auf die Walzmitte.The invention relates to a device for the automatic positioning of rolling stands with caliber rolls and these upstream rolling beams and rolling fittings on the center of the roll.

Bekannte Vorrichtungen dieser Art weisen durchweg eine, auf die Walzlinie festgelegte Walzarmatur auf, die außerhalb des Gerüstes installiert ist.Known devices of this type consist of a rolling armature which is fixed to the rolling line and is installed outside the stand.

Mit diesen Vorrichtungen läßt sich beim Verschieben der Walzgerüste mit den Walzkalibern zu deren Ausrichtung auf die Walzarmaturen und die Walzmitte infolge der unvermeidlichen Toleranzen durchweg nicht die erforderliche Genauigkeit erreichen. Der starke Schmutzanfall an den Walzgerüsten erschwert diese Ausrichtung noch zusätzlich.With these devices it is not possible to achieve the required accuracy when moving the roll stands with the roll calibres to align them with the roll fittings and the center of the roll due to the inevitable tolerances. The heavy accumulation of dirt on the roll stands makes this alignment even more difficult.

Der Erfindung liegt die Aufgabe zugrunde, diese Schwierigkeiten und Nachteile bei der Ausrichtung zu beseitigen und die Ausrichtung selbst zu vereinfachen.The object of the invention is to eliminate these difficulties and disadvantages in the alignment and to simplify the alignment itself.

Diese Aufgabe wird durch einen ortsfesten, die Träger der Walzarmatur aufnehmenden Führungsrahmen gelöst, auf dem das Walzgerüst relativ zu diesem Träger verschieb- und gegenüber dem Träger festlegbar angeordnet ist.This object is achieved by a stationary guide frame receiving the supports of the rolling armature, on which the rolling stand is displaceable relative to this support and can be fixed relative to the support.

Durch diese Ausbildung der Vorrichtung wird erreicht, daß nach Verschieben des Walzgerüstes die jeweiligen Kaliber der Walzen automatisch auf die mit ihrem Träger bereits in der Walzlinie positionierten Walzarmaturen ausgerichtet und festgelegt werden können.This configuration of the device ensures that the respective calibers of the rolls can be automatically aligned and fixed to the rolling fittings already positioned in the rolling line with their carrier after the rolling stand has been moved.

Wie die Erfindung weiter vorsieht, können die Träger der Walzarmaturen in dem Führungsrahmen um eine parallel zu den Walzenachsen, quer zur Walzrichtung liegende Achse schwenkbar angelenkt werden, dabei können den Kalibern der Walzen zugeordnete Positionierausnehmungen in den walzgerüstfesten Walzbalken und ein, am Träger der Walzarmaturen angeordneter, in diese Ausnehmungen einbringbarer Positionieranschlag vorgesehen werden. Der Träger der Walzarmaturen kann dabei bei Horizontalwalzgerüsten aus einem, einerseits an dem Führungsrahmen und andererseits an einer, die beiden Ständer des Walzgerüstes verbindenden, parallel zu den Walzenachsen oberhalb der Walzlinie liegenden Traverse angelenkten Scharnierbügel bestehen. An den Trägern der Walzarmaturen können, oberhalb und ggfs. unterhalb der Armaturen angeordnete Sprühdüsenträger für, auf die Walzen aufbringbare Kühlmittel vorgesehen werden. Diese Sprühdüsenträger können um die Schwenkachse der Träger der Walzarmaturen schwenk- und feststellbar angeordnet und dabei mit unmittelbar oder mittelbar gegen das Walzgerüst abgestützten Stellanschlägen ausgestattet sein. Weiter kann eine, an sich bekannte, fest auf dem Führungsrahmen angeordnete, mit dem Walzgerüst verbundene, gegen den Druck eines Hydraulikpuffers wirkende Spindel-Verschiebeeinrichtung vorgesehen werden.As the invention further provides, the supports of the roll fittings can be pivoted in the guide frame about an axis parallel to the roll axes, transverse to the rolling direction, thereby positioning recesses assigned to the calibres of the rolls can be arranged in the roll stand fixed to the roll stand and one arranged on the support of the roll fittings , positioning stop which can be introduced into these recesses are provided. In the case of horizontal rolling stands, the support of the rolling fittings can consist of a hinge bracket which is articulated on the one hand on the guide frame and on the other hand on a hinge bracket which connects the two uprights of the rolling stand and lies parallel to the roll axes above the rolling line. On the supports of the rolling fittings, spray nozzle supports arranged above and, if necessary, below the fittings can be provided for coolants that can be applied to the rollers. These spray nozzle supports can be arranged so as to be pivotable and lockable about the pivot axis of the supports of the rolling fittings and can be equipped with adjusting stops supported directly or indirectly against the rolling stand. Furthermore, a spindle displacement device, known per se and arranged fixedly on the guide frame and connected to the roll stand and acting against the pressure of a hydraulic buffer, can be provided.

Wie aus den Fig. 2, 3 und 4 zu ersehen, weist das mit Horizontalwalzen 1 und 2 versehene Walzgerüst W Walzenständer 3 und 4 auf und ist auf den Fußauslegern 5 und 6 eines Führungsrahmens R in Richtung des eingezeichneten Doppelpfeils S in diesem Führungsrahmen R verschiebbar. Der Träger 7 der Walzarmaturen 8 ist an einem Scharnierbügel 9 angeordnet, der einerseits mit einer Lagerhülse 9a an dem Führungsrahmen R und andererseits mit einer weiteren Lagerhülse 9b an einer, die beiden Walzenständer 3 und 4 oberhalb der Horizontalwalzen 1 und 2 verbindenden Traverse 10 angelenkt ist. Den Horizontalwalzen 1 und 2 vor- und nachgeordnet sind die beiden, fest mit den Walzenständern 3 und 4 verbundenen Walzbalken 11 und 12.As can be seen from FIGS. 2, 3 and 4, the roll stand W provided with horizontal rolls 1 and 2 has roll stands 3 and 4 and can be displaced in this guide frame R on the foot arms 5 and 6 of a guide frame R in the direction of the double arrow S shown . The carrier 7 of the rolling fittings 8 is arranged on a hinge bracket 9, which is articulated on the one hand with a bearing sleeve 9a on the guide frame R and on the other hand with a further bearing sleeve 9b on a crossbar 10 connecting the two roll stands 3 and 4 above the horizontal rolls 1 and 2 . Upstream and downstream of the horizontal rolls 1 and 2 are the two roll beams 11 and 12 which are firmly connected to the roll stands 3 and 4.

Wie aus Fig. 3 und 4 ersichtlich, weisen die Walzbalken 11 und 12 den Kalibern K der Horizontalwalzen 1 und 2 zugeordnete Positionierausnehmungen A auf, in die ein am Träger 7 der Walzarmaturen 8 angeordneter Positionieranschlag PA durch Schwenken des Trägers 7 um die Achse der Traverse 10 ein- und herausbringbar ist.As can be seen from FIGS. 3 and 4, the rolling beams 11 and 12 have positioning recesses A assigned to the calibres K of the horizontal rolls 1 and 2, into which a positioning stop PA arranged on the support 7 of the rolling fittings 8 can be obtained by pivoting the support 7 about the axis of the crossmember 10 can be brought in and out.

Oberhalb der Walzarmaturen 8 sind an deren Träger 7 Sprühdüsenträger 13, 14 bzw. 15, 16 angeordnet, von diesen sind die oberhalb der oberen Horizontalwalze 1 befindlichen Sprühdüsenträger 13, 14 mit Lagerhülsen 13a bzw. 14a, relativ zu dem Träger 7 schwenkbar auf den Traversen 10 gelagert. Die Hydraulikzylinder 17, 18 stützen sich an, mit den Walzenständern 3 bzw. 4 verbundenen Auflageblöcken 20 bzw. 21 ab. Mit diesem Schwenkantrieb wird die Schwenkbewegung des Trägers 7 erzeugt.Above the roller valves 8, 7 spray nozzle carriers 13, 14 and 15, 16 are arranged on the carrier thereof, of which the spray nozzle carriers 13, 14 with bearing sleeves 13a and 14a located above the upper horizontal roller 1 are pivotable on the crossbeams relative to the carrier 7 10 stored. The hydraulic cylinders 17, 18 are supported on support blocks 20 and 21 connected to the roll stands 3 and 4, respectively. With this swivel drive, the swivel movement of the carrier 7 is generated.

Das Walzgerüst W wird mit Hilfe hier nicht dargestellter Verschiebemittel auf den Fußauslegern 5, 6 in Richtung des Pfeils S (Fig. 2) relativ zu dem Träger 7 der Walzarmatur 8, der sich in der in Fig. 3, rechts in der Zeichnung, dargestellten Schwenklage nach außen befindet, bis sich das gewünschte Kaliber K der Walzen 1, 2 zwischen den Walzarmaturen 8 befindet. Der Träger 7 mit der Walzarmatur 8 wird dann in die in Fig. 3 links in der Zeichnung wiedergegebene Stellung geschwenkt, wobei der Positionieranschlag PA in die ihm jeweils gegenüberliegende Positionierausnehmung A im Walzbalken 11 bzw. 12 einfährt. Die Konizität sowohl der Außenwandung des Positionieranschlags PA als auch der Innenwandungen der Positionierausnehmung A bewirkt dabei eine genaue Einmittung des Kalibers A auf die durch den Positionieranschlag PA bestimmte Walzmitte.The rolling stand W is with the aid of shifting means, not shown here, on the foot arms 5, 6 in the direction of the arrow S (FIG. 2) relative to the support 7 of the rolling armature 8, which is shown in FIG. 3, on the right in the drawing Pivotal position to the outside until the desired caliber K of the rollers 1, 2 is between the roller fittings 8. The carrier 7 with the rolling armature 8 is then pivoted into the position shown on the left in FIG. 3 in the drawing, the positioning stop PA moving into the respective positioning recess A in the rolling beam 11 and 12, respectively. The taper of both the outer wall of the positioning stop PA and the inner walls of the positioning recess A causes the caliber A to be precisely centered on the rolling center determined by the positioning stop PA.

Die Ausbildung nach den Fig. 5 und 6 entspricht der nach den Fig. 2 bis 4 mit der Maßgabe, daß hier ein Walzgerüst W' für Vertikalwalzen 1', 2' dargestellt ist. Der Träger 7' der Walzarmaturen 8' ist hier mit einer Lagerhülse 9a' an den Führungsrahmen R' angelenkt. Der (hier nicht dargestellte) Positionieranschlag greift in die in Fig. 5 wiedergegebenen Positionierausnehmungen A' in dem Walzbalken 11' ein. Das Walzgerüst W' wird bei dieser Ausbildung nicht auf den Fußauslegern 5', 6', sondern in Führungsnuten 22, 23 des Führungsrahmens R' verschoben.5 and 6 corresponds to that of FIGS. 2 to 4 with the proviso that here a roll stand W 'for vertical rolls 1', 2 'is shown. The carrier 7 'of the rolling fittings 8' is articulated here to the guide frame R 'with a bearing sleeve 9a'. The positioning stop (not shown here) engages in the positioning recesses A 'shown in FIG. 5 in the rolling beam 11'. In this embodiment, the roll stand W 'is not moved on the foot brackets 5', 6 ', but in guide grooves 22, 23 of the guide frame R'.

Aus Fig. 1 geht eine Verschiebeeinrichtung für das aus den Walzenständern 3, 4 und der Traverse 10 und den Horizontalwalzen 1 und 2 bestehende Walzgerüst W hervor, das auf einem Führungsrahmen R in Richtung des eingezeichneten Doppelpfeils S verschiebbar geführt ist. An das Walzgerüst W greift die Gewindespindel 23 eines von einem Motor 25 angetriebenen Spindelgetriebes 24 an. Die Verschiebung erfolgt gegen die Kraft einer Kolben-Zylinder-Anordnung 26, die das in der Verschieberichtung auftretende Spiel eliminiert.1 shows a shifting device for the roll stand W consisting of the roll stands 3, 4 and the cross member 10 and the horizontal rolls 1 and 2, which is guided on a guide frame R in the direction of the double arrow S shown. The threaded spindle 23 of a spindle gear 24 driven by a motor 25 acts on the roll stand W. The displacement takes place against the force of a piston-cylinder arrangement 26, which eliminates the play occurring in the displacement direction.
