Abstract

A roll stand or a roll assembly can be displaced on a track (11) extending transverse to the rolling direction by a piston-cylinder unit arranged below the roll driving spindles (6, 7) parallel to the track (11). In order to create a simple, reliable and space-saving displacement device having a long displacement path, a piston-cylinder unit (12, 13), which is connected to the roll assembly or to a roll stand, is connected via a coupling part guided in a defined fashion parallel to the track (11) to a piston-cylinder unit (19, 20), arranged fixed below the roll stand, in such a way that the installation site of the roll assembly (2, 3, 4, 5) or of the roll stand corresponds to a retraction position of the piston-cylinder unit (12, 13) connected thereto, and to an extension position of the fixed piston-cylinder unit (19, 20). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Verschieben eines Walzeneinbaus oder eines Walzgerüstes auf einer quer zur Walzrichtung verlaufenden Bahn mit einer unterhalb der Walzenantriebsspindeln parallel zur Verschiebebahn angeordneten Kolben-Zylinder-Einheit.The invention relates to a device for moving a roll installation or a roll stand on a web running transversely to the rolling direction with a piston-cylinder unit arranged below the roll drive spindles parallel to the moving track.

In Blech und Profilwalzwerken werden zum Walzenwechsel Walzeneinbauten bzw. Walzgerüste auf horizontalen Bahnen quer zur Walzrichtung verschoben. Als Verschiebeantriebe sind Spindeltriebe, Zahnstangentriebe und beidseitig beaufschlagbare Kolben-Zylinder-Einheiten bekannt.In sheet metal and profile rolling mills, roll internals or roll stands are moved horizontally across the rolling direction to change the rolls. Spindle drives, rack and pinion drives and piston-cylinder units which can be acted upon on both sides are known as displacement drives.

Zur Freihaltung des Verschiebebereichs ist es vorteilhaft, die Kolben-Zylinder-Einheiten unterhalb der Antriebsspindeln der Walzen anzuordnen. Der Platz zwischen Walzgerüst und Walzengetriebe reicht jedoch manchmal nicht aus, um für lange Verschiebewege erforderliche langhubige Zylinder unterzubringen. Teleskopzylinder werden von den Betriebsleitungen wegen der hohen Kosten und der ungünstigen Betriebsbedingungen nur ungern akzeptiert.To keep the displacement area clear, it is advantageous to have the piston-cylinder units below the drive pin to arrange the rollers. However, the space between the roll stand and the roller gearbox is sometimes not sufficient to accommodate the long-stroke cylinders required for long displacement distances. Operating lines are reluctant to accept telescopic cylinders due to the high costs and unfavorable operating conditions.

Aufgabe der Erfindung ist die Schaffung einer einfachen und betriebssicheren hydraulischen Verschiebevorrichtung, die bei geringem Platzbedarf einen großen Verschiebeweg ermöglicht.The object of the invention is to provide a simple and reliable hydraulic shifting device which enables a large displacement distance in a small space.

Nach der Erfindung wird dies dadurch erreicht, daß eine mit dem Walzeneinbau oder einem Walzgerüst verbundene Kolben-Zylinder-Einheit über ein parallel zur Verschiebebahn definiert geführtes Kupplungsstück derart mit einer unter dem Walzgerüst ortsfest angeordneten Kolben-Zylinder-Einheit verbunden ist, daß der Einbaustellung des Walzeneinbaus oder des Walzgerüstes eine eingefahrene Position der damit verbundenen Kolben-Zylinder-Einheit und eine ausgefahrene Position der ortsfesten Kolben-Zylinder-Einheit entspricht.According to the invention, this is achieved in that a piston-cylinder unit connected to the roll installation or a roll stand is connected via a coupling piece, which is defined parallel to the sliding path, to a piston-cylinder unit arranged in a stationary manner under the roll stand, in such a way that the installation position of the Roller installation or the roll stand corresponds to a retracted position of the associated piston-cylinder unit and an extended position of the stationary piston-cylinder unit.

Auf diese Weise wird eine einfache und betriebssichere Verschiebevorrichtung geschaffen, mit der bei geringem Platzbedarf ein großer Verschiebeweg erreichbar ist. Die Vorrichtung kann auch bei geringem Abstand zwischen Walzgerüst und Getriebe unter dem Walzgerüst und den Spindeln eingebaut werden, so daß besondere Durchlässe am Getriebe und Motor nicht erforderlich sind.In this way, a simple and reliable displacement device is created, with which a large displacement distance can be achieved with a small space requirement. The device can also be installed under a small distance between the roll stand and gear under the roll stand and the spindles, so that special passages on the gear and motor are not required.

Gemäß einem weiteren Merkmal der Erfindung ist das Kupplungsstück als Kreuzhebel ausgebildet, dessen oberer Arm an der mit dem Walzeneinbau oder dem Walzgerüst verbundenen Kolben-Zylinder-Einheit und dessen unterer Arm an der ortsfesten Kolben-Zylinder-Einheit angelenkt sind und an dessen Seitenarmen Führungsrollen gelagert sind, denen eine untere und eine obere parallel zur Verschiebebahn verlaufende Führungsbahn zugeordnet sind.According to a further feature of the invention, the clutch piece designed as a cross lever, the upper arm of which is articulated to the piston-cylinder unit connected to the roll installation or the roll stand and the lower arm of which is articulated to the fixed piston-cylinder unit and on the side arms of which guide rollers are mounted, with a lower and an upper one parallel to the sliding track are assigned.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen

  • Fig. 1 schematisch ein Walzgerüst mit einer Verschiebevorrichtung für den Walzeneinbau und
  • Fig. 2 das Walzgerüst mit aus dem Gerüst gefahrenen Walzensatz.
In the drawing, an embodiment of the invention is shown. Show it
  • Fig. 1 shows schematically a roll stand with a displacement device for roll installation and
  • Fig. 2 shows the roll stand with the set of rolls moved out of the stand.

Bei dem dargestellten Walzgerüst sind in Walzenständern 1 Walzen 2, 3 mit ihren Einbaustücken 4, 5 gelagert. Die Walzen 2, 3 sind über Spindeln 6, 7 und Kupplungstreffer 6a, 7a mit einem Getriebe 8 verbunden. Die Einbaustücke 5 der unteren Walze 3 stehen auf einem Ausfahrwagen 9, der mit Räder 10 auf Ausfahrschienen 11 aus dem Walzgerüst fahrbar ist. An dem Ausfahrwagen 9 ist die Kolbenstange 12 eines horizontal angeordneten Druckmittelzylinders 13 durch einen Bolzen 14 angebracht.In the roll stand shown, 1 rolls 2, 3 with their chocks 4, 5 are stored in roll stands. The rollers 2, 3 are connected to a gear 8 via spindles 6, 7 and coupling hit 6a, 7a. The chocks 5 of the lower roller 3 stand on an extension carriage 9, which can be moved with wheels 10 on extension rails 11 from the roll stand. The piston rod 12 of a horizontally arranged pressure medium cylinder 13 is attached to the extension carriage 9 by a bolt 14.

Der Druckmittelzylinder 13 ist am oberen Arm eines Kreuzhebels 15 durch Bolzen 16 angelenkt. Zur definierten Horizontalführung ist der Kreuzhebel 15 mit Rädern 17 versehen, die in einer zwischen Walzenständer 1 und Getriebe 8 parallel zu den Ausfahrschienen 11 angeordneten U-Führung 18 laufen. An einem unteren Arm des Kreuzhebels 15 ist die Kolbenstange 19 eines unter dem Walzgerüst horizontal angeordneten und an einem Walzenständer 1 befestigten Druckmittelzylinders 20 durch einen Bolzen 21 angelenkt.The pressure medium cylinder 13 is articulated on the upper arm of a cross lever 15 by bolts 16. For defined horizontal guidance, the cross lever 15 is provided with wheels 17 which are arranged in a U-guide 18 arranged between the roller stand 1 and the gear 8 parallel to the extension rails 11 to run. On a lower arm of the cross lever 15, the piston rod 19 of a pressure medium cylinder 20, which is arranged horizontally under the roll stand and fastened to a roll stand 1, is articulated by a bolt 21.

Zum Ausbauen der Walzen 2, 3 mit ihren Einbaustücken 4, 5 werden die Kolbenstange 12 und 19 durch Beaufschlagung der Druckmittelzylinder 13 und 20 ausgefahren. Ein neuer Walzensatz wird anschließend durch entgegengesetzte Beaufschlagung der Zylinder 13, 20 in die Einbaustellung gefahren.To remove the rollers 2, 3 with their chocks 4, 5, the piston rods 12 and 19 are extended by acting on the pressure medium cylinders 13 and 20. A new roller set is then moved into the installation position by acting on the cylinders 13, 20 in the opposite direction.
