Description

Die Erfindung bezieht sich auf ein Walzgerüst mit in zwei parallelen Walzenständem gelagerten und an einer Seite mit Antriebselementen kuppelbaren Tragwellenpaaren für auf diese in einen Sitz zwischen beiden Walzenständem aufschiebbare Walzringe, bei dem der den Antriebselementen der Tragwellen abgewandte Walzenständer mit den Lagem in Walzachsrichtung von dem anderen Walzenständer wegbewegbar ist und an dem beweglichen Walzenständer mit den Walzringen verbind-und lösbare Halteelemente angeordnet sind, die mit dem Innenring des jeweiligen Lagers direkt oder indirekt verbunden sind und auf deren Außenumfang der Walzring aufschiebbar ist.The invention relates to a roll stand with bearing shaft pairs mounted in two parallel roll stands and which can be coupled on one side with drive elements for roll rings which can be pushed onto them in a seat between the two roll stands, in which the roll stand facing away from the drive elements of the support shafts with the bearings in the rolling axis direction from the other Roll stand is movable away and on the movable roll stand with the roll rings connectable and detachable holding elements are arranged, which are connected directly or indirectly to the inner ring of the respective bearing and on the outer circumference of which the roll ring can be pushed.

Walzgerüste dieser Art, z. B. nach der EP-A 0 163 104 (veröffentlicht am 4. 12. 85), die auch bei größeren Gerüstabmessungen, wie sie für Knüppel-Formstahl oder auch andere Walzenstraßen notwendig sind, erlauben es, die Walzringe auszutauschen, ohne daß es einer Verstezung oder der Demontage des gesamten Walzgerüstes bedarf. Der den Antriebselementen der Tragwellen abgewandte Walzenständer wird 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 Halteelementen 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 Walzenständem zusammengebauten Walzgerüst die jeweilige in beiden Walzenständem 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.Roll stands of this type, e.g. B. according to EP-A 0 163 104 (published on December 4, 85), which even with larger scaffolding dimensions, such as are necessary for billet-shaped steel or other roller mills, allow the rolling rings to be replaced without one Bracing or dismantling of the entire roll stand is required. The roller stand facing away from the drive elements of the supporting shafts is moved axially in the direction of the other roller stand for the purpose of changing the rolling rings with the bearings removed from the supporting shaft pair, and the supporting shaft pair can be held and fixed in the other one-sided cantilevered cantilever position will. 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 sleeve 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 adjustment of the rolling rings to 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 gattungsgemäße Ausbildung des Walzgerüstes so zu verbessern, daß diese Nachteile und Schwierigkeiten beseitigt werden.The invention has for its object to improve the generic design of the rolling mill so that these disadvantages and difficulties are eliminated.

Die Aufgabe wird dadurch gelöst, daß bei einer aus zwei in dem einen und in dem anderen Walzenständer gelagerten mit den einander zugewandten Stirnseiten auf die Stirnseiten des Walzrings aufleg- und unter Axialdruck mit diesem kuppelbaren Ringstücken bestehende Tragwelle, und die Stirnseiten der Ringstücke nach außen geneigt verlaufende konische Flächenabschnitte aufweisen. Es besteht auch die Möglichkeit, die konisch verlaufenden Flächenabschnitte an auf Ringabsätzen der Ringstücke aufsetzbaren Zwischenringen anzuordnen.The object is achieved in that in the case of a bearing shaft which is supported by two in one and in the other, with the mutually facing end faces, placed on the end faces of the rolling ring and under axial pressure with this couplable ring pieces, and the end faces of the ring pieces inclined outward have running conical surface sections. There is also the possibility of arranging the conical surface sections on intermediate rings which can be placed on ring shoulders of the ring pieces.

Bei der erfindungsgemäßen Ausbildung wird der Walzring zwischen den beiden Ringstücken in bekannter Weise nur durch Beaufschlagung mit axialem 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 Drehmomentenübertragung 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 centered on the axis of rotation only by the application of axial pressure 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 Roll stand transported away. This results in a precise setting option for the center of the roll and an additional security in the transmission of the torque via the two ring pieces to the end faces of the roll ring if the torque is transmitted via the outwardly inclined conical 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 with reference to 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 Stück. Die beiden Ringstücke 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 releasably 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 braced against each other in the axial direction by a hydraulic tension nut and detached 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 form a composite element under the clamping pressure of the hydraulic nut 18, 19, 20, 21, 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 inclined running 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 roller 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 disassembling the ring nut 20, the roller stand 2 can be moved away from the roller stand 1 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 shown. Only the bearing 5 with the ring piece 27 remains in this stand and the tie rod 17 of the hydraulic nut screwed into this.

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 VerschleiBteile.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 interchangeable 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 roll ring 43 when the roll stand 2 is extended laterally.
