The intention is to present a shifting device with which even high shifting forces can be reliably transmitted and which can be assembled rapidly and easily. The invention therefore provides that the axial shifting be effected by means of a clamping arrangement (3) which is in releasable operative connection with the roll journal (8) of a rolling-mill roll (1). The releasable clamping connection between clamping arrangement (3) and roll journal (8) is here of positively engaging design. It is particularly expedient if the clamping arrangement (3) is designed as a compact unit consisting of a clamping head (10), with at least one axially prestressed compression spring (13), which acts on the clamping discs (14) acting as clamping elements, the clamping discs (14) clamping a radially elastic clamping bush (15) to the roll journal (8), the clamping discs (14) being releasable from their clamping position by means of a hydraulic fluid counter to the action of the compression spring (13) and the clamping discs (14) being, on the one hand, supported axially against a housing part (10) and, on the other hand, braced against the compression spring (13) via an axially shiftable hollow cylinder (16), and the clamping bush (15) being provided in the region of the clamping discs (14) acting on it with an inner profiling (19) which, together with the complementary profiling (18) on the roll journal (8), forms the releasable clamping connection. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum axialen Verschieben von sich drehenden Wellen, insbesondere von Walzwerkswalzen, wobei die axiale Verschiebung mittels einer Klemmeinrichtung erfolgt, die mit dem Walzenzapfen einer Walzwerkswalze in lösbarer Wirkungsverbindung steht und die lösbare Klemmverbindung zwischen Klemmeinrichtung und Walzenzapfen formschlüssig ausgebildet ist.The invention relates to a device for the axial displacement of rotating shafts, in particular of rolling mill rolls, the axial displacement being carried out by means of a clamping device which has a releasable operative connection to the roll neck of a rolling mill roll and the releasable clamping connection between the clamping device and the roll pin is of a positive fit.

Bisher wurden für die axiale Verschiebung von Arbeits- bzw. Zwischenwalzen verschiedene Kupplungsarten für die Axialkraftübertragung ausgeführt, die alle sehr konstruktionsaufwendig sind, da für jede Walzengröße eine andere Vorrichtung benötigt wurde. Der Einsatz bekannter Vorrichtungen kann zudem nur im Zusammenhang mit relativ großen Walzenzapfendurchmessern erfolgen.So far, various types of coupling for the axial force transmission have been carried out for the axial displacement of work or intermediate rolls, all of which are very expensive to construct, since a different device was required for each roll size. Known devices can also only be used in connection with relatively large roll neck diameters.

In der DE-A1-2845266 wird eine Ringspann- Sicherheits- Klemmeinheit zwar für verschiedene Anwendungsgebiete beschrieben, allerdings nicht für Walzwerkswalzen. Auch können konstruktionsbedingt nur Verschiebekräfte bis 20 t kraftschlüssig übertragen werden.DE-A1-2845266 describes a ring clamping safety clamping unit for different areas of application, but not for Rolling mill rolls. Due to the design, only displacement forces of up to 20 t can be transmitted in a non-positive manner.

Die DE-A1-3145134 betrifft eine gattungsgleiche Axialverschiebevorrichtung, die sehr konstruktionsaufwendig ist und zudem wird für jede Walzengröße eine andere Vorrichtung benötigt. Der Einsatz dieser Vorrichtung ist nur im Zusammenhang mit großen Walzenzapfendurchmessern möglich. Während des Betriebes werden zudem Hydraulikmedien benötigt, wodurch drehende Ölzuführungen mit entsprechend aufwendigen Dichtungen erforderlich sind.DE-A1-3145134 relates to an axial displacement device of the same type, which is very expensive to construct and in addition a different device is required for each roll size. This device can only be used in connection with large roll neck diameters. Hydraulic media are also required during operation, which means that rotating oil feeds with correspondingly complex seals are required.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung vorzustellen, mittels derer die genannten Nachteile vermieden bzw. Schwierigkeiten ausgeräumt werden können. Insbesondere soll die Verschiebevorrichtung auch hohe Verschiebekräfte sicher übertragen sowie schnell und leicht montierbar sein.It is therefore an object of the invention to present a device by means of which the disadvantages mentioned can be avoided or difficulties can be eliminated. In particular, the displacement device should also reliably transmit high displacement forces and be quick and easy to assemble.

Die Lösung der gestellten Aufgabe gelingt erfindungsgemäß dadurch, daß die Klemmeinrichtung als kompakte Einheit ausgebildet ist, bestehend aus einem Klemmkopf, mit zumindest einer axial vorgespannten Druckfeder, die auf die als Klemmkörper wirkenden Spannscheiben einwirkt, wobei die Spannscheiben eine radialelastische Spannbüchse mit dem Walzenzapfen verklemmen, wobei die Spannscheiben mittels eines hydraulischen Druckmittels entgegen der Wirkung der Druckfeder aus ihrer Klemmposition lösbar sind, und wobei sich die Spannscheiben einerseits axial an einem Gehäuseteil abstützen und andererseits über einen axial verschiebbaren Hohlzylinder mit der Druckfeder verspannt sind und die Spannbüchse im Bereich der auf sie einwirkenden Spannscheiben innen mit einer Profilierung versehen ist, die zusammen mit einer komplementären Profilierung auf dem Walzenzapfen die lösbare Klemmverbindung bildet.The object is achieved according to the invention in that the clamping device is designed as a compact unit, consisting of a clamping head with at least one axially preloaded compression spring, which acts on the clamping disks acting as clamping bodies, the clamping disks clamping a radially elastic clamping sleeve with the roll neck, wherein the tensioning disks can be released from their clamping position against the action of the compression spring by means of a hydraulic pressure medium, and wherein the tensioning disks are axially on one hand Support the housing part and, on the other hand, are clamped with the compression spring via an axially displaceable hollow cylinder and the clamping bush is provided with a profile in the area of the clamping discs acting on it, which together with a complementary profile on the roll neck forms the releasable clamping connection.

Die erfindungsgemäße Klemmeinrichtung läßt sich sowohl für die Verschiebung von Arbeitswalzen, als auch von Zwischenwalzen oder Stützwalzen in beliebiger Kombination verwenden, insbesondere auch in Walzgerüsten mit sogenannten Flaschenwalzen, die zur Änderung des Walzspaltprofils gegeneinander verschoben werden müssen, wobei ein einfaches Lösen und Klemmen der Kupplung gegeben ist. Das Kupplungssystem ist zwar für alle Arten der Axialverschiebung von Walzen in Walzgerüsten verwendbar, insbesondere aber für nicht angetriebene Walzen. Darüberhinaus kann die Kupplung bei angetriebenen Walzen eingesetzt werden, wobei die Welle für die Axiallager dann als Hohlwelle ausgebildet ist. Die Antriebsmomente werden dabei über die Hohlwelle formschlüssig auf die Walze übertragen, und die Axialkräfte über die erfindungsgemäße Walzenkupplung. Durch die formschlüssige Klemmverbindung zwischen Klemmeinrichtung und Walzenzapfen lassen sich beliebig hohe Verschiebekräfte übertragen, beispielsweise bis zu 50 t. Die neue Vorrichtung erlaubt ferner die Verwendung kleiner Walzenzapfendurchmesser und es wird eine geringe Baulänge wegen eines kurzen Walzenzapfens ermöglicht, wodurch auch der Walzenwechselwagen in verkürzter Bauweise ausgeführt werden kann. Die erfindungsgemäße Vorrichtung hat vorteilhaft nur eine geringe Anzahl von Bauteilen. Die Kupplungseinheit kann schnell und sicher gewechselt werden. Besonders vorteilhaft sind die Walzenzapfen im Bereich des Kupplungssystems austauschbar. Insgesamt ergeben sich niedrigere Herstellkosten.The clamping device according to the invention can be used for the displacement of work rolls, as well as intermediate rolls or back-up rolls in any combination, in particular also in roll stands with so-called bottle rolls, which have to be moved against each other to change the roll gap profile, with a simple release and clamping of the coupling being given is. The coupling system can be used for all types of axial displacement of rolls in roll stands, but in particular for non-driven rolls. In addition, the clutch can be used with driven rollers, the shaft for the axial bearings then being designed as a hollow shaft. The drive torques are positively transmitted to the roller via the hollow shaft, and the axial forces are transferred via the roller clutch according to the invention. The form-fitting clamping connection between the clamping device and the roll neck allows any high displacement forces to be transmitted, for example up to 50 t. The new device also allows the use of small roll neck diameters and a small overall length is made possible because of a short roll neck, which also shortens the roll changing carriage Construction can be carried out. The device according to the invention advantageously has only a small number of components. The coupling unit can be changed quickly and safely. The roller journals are particularly advantageously interchangeable in the area of the coupling system. Overall, there are lower manufacturing costs.

In vorteilhafter Ausgestaltung der Erfindung besteht die Profilierung aus parallelen Ringnuten. Diese Art der lösbaren Klemmverbindung, vorzugsweise in trapezförmiger Ausbildung der Ringnuten, hat sich in der Praxis als besonders haltbar und betriebssicher herausgestellt.In an advantageous embodiment of the invention, the profiling consists of parallel ring grooves. This type of releasable clamp connection, preferably in a trapezoidal design of the ring grooves, has proven to be particularly durable and reliable in practice.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Klemmeinrichtung eine Axiallagerung vorgeschaltet, wobei die Klemmeinrichtung einen mit dem Klemmkopf fest verbundenen Klemmkopfzapfen besitzt, der von in einem Axiallagergehäuse angeordneten Axiallagern umgeben ist. Die axialen Verschiebekräfte für die Walze sind über das Axiallagergehäuse auf den Klemmkopfzapfen, den Klemmkopf bzw. letztlich über die Flanken der Rillen der Spannbüchse in den Walzenzapfen der Walze übertragbar. Der Walzenzapfen kann dadurch kürzer ausgeführt werden. Der Klemmkopfzapfen der Klemmeinheit bildet sozusagen eine Verlängerung des Walzenzapfens. Hierdurch ergeben sich Kosteneinsparungen, da der Klemmkopfzapfen nur einmal vorhanden sein muß und für verschiedene Walzen verwendbar ist.According to a further advantageous embodiment of the invention, the clamping device is preceded by an axial bearing, the clamping device being a clamping head pin fixedly connected to the clamping head has, which is surrounded by axial bearings arranged in a thrust bearing. The axial displacement forces for the roller can be transmitted via the axial bearing housing to the clamping head pin, the clamping head or ultimately via the flanks of the grooves of the clamping bush in the roller pin of the roller. The roll neck can therefore be made shorter. The clamping head pin of the clamping unit forms an extension of the roller pin, so to speak. This results in cost savings since the clamping head pin only has to be present once and can be used for different rolls.

Alternativ zur vorgeschalteten Axiallagerung kann es aber auch zweckmäßig und vorteilhaft sein, wenn die Axiallagerung zwischen der Klemmeinrichtung und der Walzenlagerung angeordnet ist. Die Walzenkupplung kann insbesondere bei Anordnung auf der Antriebsseite auch hinter der Axiallagerung angeordnet werden, allerdings mit dem Nachteil längerer Walzen. Von Vorteil ist die kürzere Kassettenführung der Biegeblöcke.As an alternative to the upstream axial bearing, it can also be expedient and advantageous if the axial bearing is arranged between the clamping device and the roller bearing. The roller clutch can also be arranged behind the axial bearing, in particular when arranged on the drive side, but with the disadvantage of longer rollers. The shorter cassette guide of the bending blocks is an advantage.

An seinem äußeren Ende weist der Lagerzapfen (5) einen fest verbundenen oder lösbaren Walzen- bzw. Wellenzapfen (8) auf, der von der erfindungsgemäßen Klemmeinrichtung (3) umgeben ist.Figure 1 shows the design of a rolling mill roll (1), with roll bearing (2), clamping device (3) and axial bearing (4). The roller (1) has the bearing journal (5), which is supported in a known manner in a radial bearing (6) of the chock (7).

Die Klemmkörper (14) bestehen aus Spannscheiben, die eine radialelastische Büchse (15) mit dem Walzenzapfen (8) verklemmen. Die Spannscheiben (14) stützen sich einerseits an dem Klemmkopf (10) ab und sind andererseits über einen axial verschiebbaren Hohlzylinder (16) mit der Druckfeder (13) verspannt. Die Büchse (15) weist an einem Ende einen Ringflansch (17) auf, der mit dem Klemmkopf (10) lösbar verbunden ist. Die Spannbüchse (15) ist im Bereich der auf sie einwirkenden Spannscheiben (14) innen mit einer Profilierung (nicht dargestellt) versehen, die mit einer komplementären Profilierung (18) auf dem Walzenzapfen (8) in lösbarer Wirkungsverbindung steht (vgl. insbesondere Fig. 3). Die Klemmverbindung wird aufgehoben, indem die Spannscheiben (14) und damit die Spannbüchse (15) mittels hydraulischem Druckmittel entgegen der Wirkung der Druckfeder (13) aus ihrer Klemmposition gelöst werden.The clamping device (3) consists of the clamping head (10), ie a housing with a pressure medium chamber (11) as well as a connection (12) for a hydraulic pressure medium, furthermore with at least one axially preloaded compression spring (13) which is attached to the roll neck ( 8) surrounding clamping body (14) acts. The clamping bodies (14) consist of clamping disks which clamp a radially elastic bushing (15) with the roll neck (8). The clamping discs (14) are supported on the one hand on the clamping head (10) and on the other hand are clamped to the compression spring (13) via an axially displaceable hollow cylinder (16).

The clamping connection is released by releasing the clamping disks (14) and thus the clamping bush (15) from their clamping position by means of hydraulic pressure medium against the action of the pressure spring (13).

Die Klemmeinrichtung (3) besitzt einen mit dem Klemmkopf (10) bzw. dem Gehäuse fest verbundenen Klemmkopfzapfen (20), der von der Axiallagerung (4) aufgenommen wird und vorzugsweise von zwei Axiallagern (21, 22) umgeben ist, wobei die axialen Verschiebekräfte für die Walze (1) über das Axiallagergehäuse (23) auf den Klemmkopfzapfen (20), den Klemmkopf (10) bzw. letztlich über die Flanken der Profilierungsrillen (18) zwischen der Spannbüchse (15) und dem Walzenzapfen (8) in die Walze (1) übertragen werden.The clamping device (3) has a clamping head pin (20) which is fixedly connected to the clamping head (10) or the housing and which is received by the axial bearing (4) and is preferably surrounded by two axial bearings (21, 22), the axial displacement forces for the roller (1) via the axial bearing housing (23) on the clamping head pin (20), the clamping head (10) or ultimately via the flanks of the profiling grooves (18) between the clamping bush (15) and the roller pin (8) into the roller (1) can be transferred.

Der Klemmkopf (10) umschließt wiederum den Druckmittelraum (11), der durch Nutringe (30, 31) gegenüber dem axial beweglichen Hohlzylinder (16) abgedichtet ist, wobei das Druckmittel hier über die Zuleitung (32) in den Druckmittelraum (11) gelangt. Die Zuleitung (32) befindet sich in dieser Ausführungsform im Deckel (33) des Klemmkopfes (10). Zwischen Klemmkopf (10) und Hohlzylinder (16) ist ferner die axial vorgespannte Druckfeder (13) angeordnet, bestehend aus fünf Tellerfedern, die auf die den Walzenzapfen (8) umgebenden Klemmkörper bzw. die Spannscheiben (14) einwirken und die längsgeschlitzte Spannhülse bzw. Büchse (15) mit dem Walzenzapfen (8) verklemmen. Die Büchse (15) hat an einem Ende einen Ringflansch (17), der mit dem Klemmkopf (10) fest verschraubt ist. Die Spannscheiben (14) werden (wie bei Fig. 1 beschrieben) mittels hydraulischem Druckmittel entgegen der Wirkung der Druckfeder (13) aus ihrer Klemmposition gelöst.

The clamping head (10) in turn surrounds the pressure medium chamber (11), which is sealed by means of grooved rings (30, 31) with respect to the axially movable hollow cylinder (16), the pressure medium reaching the pressure medium chamber (11) via the feed line (32). In this embodiment, the feed line (32) is located in the cover (33) of the clamping head (10). Between the clamping head (10) and Hollow cylinder (16) is also arranged the axially preloaded compression spring (13), consisting of five disc springs, which act on the clamping body or the clamping discs (14) surrounding the roll neck (8) and the longitudinally slotted clamping sleeve or bushing (15) with the Clamp roller pin (8). The bush (15) has an annular flange (17) at one end, which is screwed to the clamping head (10). The tensioning disks (14) (as described in FIG. 1) are released from their clamping position by means of hydraulic pressure medium against the action of the compression spring (13). The clamping discs (14) are supported on the cover (33) of the clamping head (10) and are clamped with the compression spring (13) via the axially displaceable hollow cylinder (16) or a hardened disc (34) arranged between them supported hardened washer (35) on the clamping head (10). The clamping sleeve (15) is provided on the inside with a profiling (19) in the area of the clamping discs (14) acting on it, which is in detachable operative connection with the complementary profiling (18) on the roll neck (8).

Figur 3 zeigt vergrößert die komplementären Profilierungen (18, 19) der Spannbüchse (15) und des Walzenzapfens (8) in gelöster Position. Besonders zweckmäßig bestehen die Profilierungen (18, 19) aus zahlreichen parallelen trapezförmigen Ringnuten bzw. Rillen (40, 41).FIG. 3 shows an enlarged view of the complementary profiles (18, 19) of the clamping bush (15) and the roll neck (8) in the released position. The profiles (18, 19) are particularly expedient from numerous parallel trapezoidal ring grooves or grooves (40, 41).

Die erfindungsgemäßen Maßnahmen sind nicht auf das in den Zeichnungsfiguren dargestellte Ausführungsbeispiel beschränkt. So kann beispielsweise, ohne den Rahmen der Erfindung wie sie in den Patentansprüchen definiert ist zu verlassen, die Profilierung der formschlüssigen Klemmverbindung in beliebiger Weise geformt sein. Die jeweilige konstruktive Ausgestaltung ist in Anpassung an die spätere Verwendung der Vorrichtung dem Fachmann anheimgestellt.The measures according to the invention are not limited to the exemplary embodiment shown in the drawing figures. For example, without leaving the scope of the invention as defined in the claims, the profiling of the positive clamping connection can be shaped in any way. The respective structural design is left to the person skilled in the art to adapt to the later use of the device.
