Description

Die Erfindung bezieht sich auf ein Walzgerüst mit, in zwei parallelen Walzenständern gelagerten und an einer Seite mit Antriebselementen kuppelbaren Tragwellenpaaren für auf diese in einen Sitz zwischen beiden Walzenständern aufschiebbare Walzringe, bei dem der, den Antriebselementen der Tragwellen abgewandte Walzenständer mit den Lagern in Walzenachsrichtung von dem anderen Walzenständer wegbewegbar ist, und die Tragwellen aus zwei, in dem einen und in dem anderen Walzenständer gelagerten, mit den einander zugewandten Stirnseiten auf die Stirnseiten des Walzrings auflegbaren, unter Axialdruck kuppelbaren Ringstücken bestehen, und die Stirnseiten der Ringstücke nach außen geneigt verlaufende Flächenabschnitte aufweisen.The invention relates to a rolling stand with, mounted in two parallel roller stands and on one side with drive elements that can be coupled with support shaft pairs for roller rings that can be slid onto a seat between the two roll stands, in which the roller stand facing away from the drive elements of the support shafts with the bearings in the direction of the roll axis from the other roller stand can be moved away, and the support shafts consist of two, in the one and in the other roller stand, with the facing end faces that can be placed on the end faces of the rolling ring, can be coupled under axial pressure, and the end faces of the ring pieces extend outwardly inclined surface sections exhibit.

Bei einer bekannten Bauart solcher Walzgerüste (DE-C-423 595) müssen die Walzringe von, außerhalb des Walzgerüstes befindlichen Halteeinrichtungen in Einbauposition zwischen die beiden Walzenständer des Walzgerüstes gebracht und gehalten, durch eine Aufeinanderzubewegung der Walzenständer, bei der konische Ansätze der Ringstücke in entsprechende stirnseitige Ausnehmungen in den Walzringen eingebracht und unter dem, auf sie ausgeübten Axialdruck festgehalten werden. Für den Ausbau der Walzringe bei einem Walzenwechsel müssen die Walzringe zunächst erneut mit Hilfe der außerhalb des Walzgerüstes befindlichen Halteeinrichtung festgehalten werden und können dann, nach Auseinanderbewegen der beiden Walzenständer mit Hilfe der erwähnten Halteeinrichtung aus dem Gerüstbereich heraus und dann in entsprechender Arbeitsweise Auswechselwalzen in das Walzgerüst eingebracht werden. Diese Arbeitsweise erfordert für den Walzenwechsel neben der Erfahrung des Bedienungspersonals beim Einbringen der Walzringe in deren Einbauposition verhältnismäßig viel Zeit und kann besonders bei schweren Walzringen zu Beschädigungen, insbesondere der konischen Ansätze führen.In a known design of such roll stands (DE-C-423 595), the roll rings of holding devices located outside the roll stand must be brought into the installation position between the two roll stands of the roll stand and held, by moving the roll stands towards one another, in the conical approaches of the ring pieces into corresponding ones end recesses are made in the rolling rings and held under the axial pressure exerted on them. To remove the roll rings when changing rolls, the roll rings must first be held again with the help of the holding device located outside the roll stand and can then, after the two roll stands have been moved apart, with the aid of the holding device mentioned, out of the stand area and then in a corresponding manner of operation, replacement rolls into the roll stand be introduced. In addition to the experience of the operating personnel when inserting the roller rings in their installation position, this method of operation requires a relatively long time for the roller change and can lead to damage, in particular to the conical approaches, in the case of heavy roller rings.

Bei einer ähnlichen Bauart bekannter Walzgerüste (EP-A-0 163 104, veröffentlicht am 4.12.85) wird der den Antriebselementen der Tragwellen abgewandte Walzenständer dabei zum Zwecke des Wechsels der Walzringe mit den dabei von dem Tragwellenpaar abgezogenen Lagern walzenaxial in Richtung von dem anderen Walzenständer wegbewegt, und das Tragwellenpaar kann in der dabei entstehenden einseitig gelagerten Kragstellung in dem anderen Walzenständer festgehalten und festgelegt werden. Die an dem beweglichen Walzenständer angeordneten mit den Walzringen verbind-und lösbaren Halteelemente sind mit dem Innenring des jeweiligen Lagers verbunden und bestehen aus einer Büchse, auf die der Walzring aufschiebbar ist. Diese den Walzring tragenden Büchsen können dann auf die in dem ortsfesten Walzenständer gelagerten in einer Kragstellung befindlichen Tragwellen aufgeschoben werden und bilden in dem aus den beiden Walzenständern zusammengebauten Walzgerüst die jeweilige in beiden Walzenständern lagernde Tragwelle für den Walzring. Neben der Notwendigkeit des Festhaltens und Festlegens des Tragwellenpaares in einer einseitig gelagerten Kragstellung in dem ortsfesten Walzenständer ist diese Ausbildungsform mit dem Nachteil behaftet, daß die für das Einstellen der Walzringe auf die Walzlinienmitte sehr wichtige, genaue axiale Positionierung der Büchse und damit des auf der Büchse sitzenden Walzrings Schwierigkeiten bereitet und einen verhältnismäßig großen technischen Aufwand erfordert.In a similar design of known roll stands (EP-A-0 163 104, published on December 4, 1985), the roll stand facing away from the drive elements of the support shafts is used for the purpose of changing the roll rings with the bearings removed from the support shaft pair in the direction of the other in the direction of the rolls Roll stand moved away, and the pair of support shafts can be held and fixed in the resulting one-sided cantilever position in the other roll stand. The holding elements which can be connected and detached to the rolling rings on the movable roller stand are connected to the inner ring of the respective bearing and consist of a bush onto which the rolling ring can be pushed. These bushings carrying the rolling ring can then be pushed onto the supporting shafts located in the cantilevered position in the stationary roller stand and form in the rolling stand assembled from the two rolling stands the respective supporting shaft for the rolling ring which is supported in both roller stands. In addition to the need to hold and fix the pair of support shafts in a cantilevered bearing in the stationary roll stand, this form of training has the disadvantage that the exact axial positioning of the bush, and thus that on the bush, which is very important for the setting of the rolling rings on the center of the rolling line seated rolling ring creates difficulties and requires a relatively large technical effort.

Der Erfindung liegt die Aufgabe zugrunde, die erfindungsgemäße Ausbildung des Walzgerüstes so zu verbessern, daß die oben geschilderten Nachteile und Schwierigkeiten beseitigt werden.The invention has for its object to improve the construction of the rolling stand according to the invention so that the disadvantages and difficulties described above are eliminated.

Diese Aufgabe wird dadurch gelöst, daß an dem beweglichen Walzenständer mit den Walzlängen verbind- und lösbare Halteelemente angeordnet sind, die mit dem Innenring des jeweiligen Lagers direkt oder indirekt verbunden, eine axiale Fortsetzung des Ringstücks bilden, und auf deren Außenumfang der Walzring von einer Seite her aufschiebbar ist und auf dem Außenumfang des Haltelementes aufliegend, von diesem gehalten wird, und wobei die Ringstücke mit dem Walzring durch eine Hyraulikmutter mit Zuganker axial zu einem, wie eine einstückige Walze wirkenden Element verspannbar sind, bei dem die Drehantriebsübertragung zwischen den Stirnseiten der Ringstücke und des jeweiligen Walzrings ausschließlich durch Reibungskraft erfolgt.This object is achieved in that on the movable roll stand with the rolling lengths connectable and releasable holding elements are arranged, which are connected directly or indirectly to the inner ring of the respective bearing, form an axial continuation of the ring piece, and on the outer circumference of the rolling ring from one side can be slid on and rests on the outer circumference of the holding element, is held by the latter, and the ring pieces can be clamped axially with the roller ring by a hydraulic nut with tie rod to form an element that acts as a one-piece roller, in which the rotary drive transmission between the end faces of the ring pieces and the respective rolling ring is done exclusively by frictional force.

Bei der erfindungsgemäßen Ausbildung wird der Walzring zwischen den beiden Ringstücken in bekannter Weise nur durch Beaufschlagung mit axialern Druck zentrisch zur Rotationsachse gehalten und wird nach Lösen dieses axialen Drucks auf den von dem im bedienungsseitigen beweglichen Walzenständer gelagerten Ringstück gehalten und beim Wegfahren dieses Walzenständers von dem antriebsseitigem Walzenständer weg transportiert Es ergibt sich eine genaue Einstellmöglichkeit auf die Walzmitte sowie eine zusätzliche Sicherheit bei der Übertragung des Drehmoments über die beiden Ringstücke auf die Stirnseiten des Walzrings wenn die Drehmomententübertragung über die nach außen geneigt konisch verlaufenden Flächen erfolgt.In the embodiment according to the invention, the rolling ring between the two ring pieces is held in a known manner centrally only by the application of axial pressure to the axis of rotation and, after releasing this axial pressure, is held on the ring piece supported by the movable roll stand on the operator side and when the roll stand moves away from the drive side Roller stand transported away There is a precise setting option on the center of the roller and additional security when transmitting the torque via the two ring pieces to the end faces of the roller ring if the torque is transferred via the outwardly tapered surfaces.

Die Erfindung wird anhand der in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Die Zeichnung zeigt in

  • Fig. 1 eine Ausbildungsform des Walzgerüstes im Axialschnitt,
  • Fig. 2 eine andere Ausbildungsform, ebenfalls im Axialschnitt ähnlich der nach Fig. 1,
  • Fig. 3 eine weitere Ausbildungsform.
The invention is explained in more detail using the exemplary embodiments shown in the drawing. The drawing shows in
  • 1 shows an embodiment of the roll stand in axial section,
  • 2 is another form of training, also in axial section similar to that of FIG. 1,
  • Fig. 3 shows another form of training.

Wie aus Fig. 1 hervorgeht, sind in dem ortsfesten Walzenständer 1 und dem mit diesem durch Steck-Schraubelemente 3 und 4 lösbar verbundenen Walzenständer 2 in Lagern 5 und 6 die Ringstücke 27 und 28 gelagert. Das im ortsfesten Walzenständer 1 gelagerte Ringstück 27 bildet mit der Antriebsspindel 16 ein Stuck. Die beiden Ringstükke 27 und 28 lassen sich in axialer Richtung gegeneinander durch eine hydraulische Zugmutter verspannen und voneinander lösen, die aus einem in die Antriebsspindel 16 eingeschraubten Zuganker 17, einem Ringzylinder 18, einem in diesen eingesetzten Ringkolben 19, einer Ringmutter 20 und einem Stellring 21 besteht.As can be seen from FIG. 1, the ring pieces 27 and 28 are mounted in bearings 5 and 6 in bearings 5 and 6 in the stationary roll stand 1 and the roll stand 2 detachably connected thereto by plug-in screw elements 3 and 4. The ring piece 27 mounted in the stationary roll stand 1 forms a piece with the drive spindle 16. The two ring pieces 27 and 28 can be clamped against one another in the axial direction by a hydraulic tension nut and released from one another, which consists of a tie rod 17 screwed into the drive spindle 16, an annular cylinder 18, an annular piston 19 inserted therein, an annular nut 20 and an adjusting ring 21 consists.

In der in der Zeichnung dargestellten Position bilden die Antriebswelle 16 mit dem Ringstück 27, der Walzring 23 und das Ringstück 28 unter dem Spanndruck der Hydraulikmutter 18, 19, 20, 21 ein zusammengesetztes Element, das wie eine einstückige Walze wirkt.In the position shown in the drawing, the drive shaft 16 with the ring piece 27, the rolling ring 23 and the ring piece 28 under the clamping pressure of the hydraulic nut 18, 19, 20, 21 form a composite element which acts like a one-piece roller.

Die Ringstücke 27 und 28 weisen an ihren dem Walzring 23 zugewandten Stirnseiten konisch nach außen geneigte verlaufende Flächen 27a, 27b bzw. 28a und 28b auf, die an entsprechende Gegenflächen an den Stirnseiten des Walzrings 23 auflegbar sind. Der Walzring wird durch die von der hydraulischen Zugmutter 17, 18, 19, 20 erzeugte axiale Spannung zentrisch in der gezeichneten Position gehalten.The ring pieces 27 and 28 have on their end faces facing the rolling ring 23 conically outwardly sloping surfaces 27a, 27b or 28a and 28b which can be placed on corresponding counter surfaces on the end faces of the rolling ring 23. The rolling ring is held in the center by the axial tension generated by the hydraulic tension nut 17, 18, 19, 20 in the position shown.

Nach Lösen des Spanndrucks und Demontage der Ringmutter 20 kann der Walzenständer 2 mit dem auf einer am Ringstück 28 sitzenden Büchse 14 aufliegenden Walzring 23 in Richtung des eingezeichneten Pfeils P vom Walzenständer 1 in axialer Richtung wegbewegt werden. In diesem Ständer verbleibt lediglich das Lager 5 mit dem Ringstück 27 und der in dieses eingeschraubte Zuganker 17 der Hydraulikmutter.After loosening the clamping pressure and dismantling the ring nut 20, the roller stand 2 can be moved in the axial direction with the roller ring 23 resting on a bush 14 seated on the ring piece 28 in the direction of the arrow P from the roller stand 1. Only the bearing 5 with the ring piece 27 and the tie rod 17 of the hydraulic nut screwed into it remain in this stand.

Beim Ausführungsbeispiel nach Fig. 2 sind anders als bei dem vorstehend erläuterten Ausführungsbeispiel die konischen Flächen 38a und 38b bzw. 37a und 37b an Zwischenringen 30 und 31 angeordnet. die auf Ringabsätze 37c bzw. 38c der Ringstücke 37 und 38 aufgesetzt sind. Diese Zwischenringe bilden dabei auswechselbare Verschleißteile.In the exemplary embodiment according to FIG. 2, in contrast to the exemplary embodiment explained above, the conical surfaces 38a and 38b or 37a and 37b are arranged on intermediate rings 30 and 31. which are placed on ring shoulders 37c and 38c of the ring pieces 37 and 38. These intermediate rings form replaceable wear parts.

Wie aus Fig. 3 ersichtlich weisen bei diesem Ausführungsbeispiel die Ringstücke 47 und 48 Zylinderansätze 47a und 48a auf, die mit Klauenkupplungselementen 50 mit axialem Spiel ineinandergreifen. Der Zylinderansatz 48a dient dabei gleichzeitig als Halteelement für den Walzring 43 beim seitlichen Ausfahren des Walzenständers 2.As can be seen from FIG. 3, in this exemplary embodiment the ring pieces 47 and 48 have cylinder extensions 47a and 48a which engage with claw coupling elements 50 with axial play. The cylinder extension 48a also serves as a holding element for the roller ring 43 when the roller stand 2 is extended laterally.
