Description

Die Erfindung betrifft eine Antriebs- und Führungsvorrichtung für die oszillierende Bewegung einer Durchlaufkokille in Stranggießanlagen, insbesondere Rogen-Stranggießanlagen mit bogenformiger Kokille, mit gestängelosem Exzenterantrieb für den die Kokille tragenden Hubtisch, mit seitlichen Leisten am Hubtisch, die die Bewegungshahn dese Hubtisches und damit der Kokille im Zusammenwirken mit beiderseits der Leisten angreifenden, ortsfesten Führungen bestimmen.The invention relates to a drive and guide device for the oscillating movement of a continuous mold in continuous casting plants, in particular roe continuous casting plants with an arcuate mold, with rodless eccentric drive for the lifting table carrying the mold, with side strips on the lifting table, which the movement tap of the lifting table and thus the mold in cooperation with stationary guides that attack both sides of the strips.

Die oszillierenden Bewegungen von Stranggießkokillen werden bekannterweise über Lenkhebel- und Exzentersysteme erzeugt. Dabei weisen allerdings die Ausführungen, bei denen die Bewegung auf die Kokille mittels Lenkhebel übertragen wird (7.B. DE-OS 1 758 554), den großen Nachteil auf, daß sich wegen der viel-fältigen Verzweigungen und der damit verbundenen großen Anzahl von Gelenkstellen bei Verschleiß das Lagerspiel addiert, was zu mangelnder Genauigkeit und zu einer Veränderung der Lage des Hubtisches führt. Eine Mindesttofleranz in der Führung der Stranggießkokille gegenüber dem im Stützwalzengerüst geführten Strang muß aber unbedingt eingehalten werden.The oscillating movements of continuous casting molds are known to be generated via steering lever and eccentric systems. However, the designs in which the movement is transmitted to the mold by means of a steering lever ( 7 .B. DE-OS 1 758 554) have the major disadvantage that, owing to the manifold branches and the large number associated with them Joint positions add up to the bearing play when worn, which leads to a lack of accuracy and a change in the position of the lifting table. However, a minimum tolerance in the guidance of the continuous casting mold compared to the strand guided in the backup roll stand must be observed.

Ein bekannter Exzenterantrieb (DE-AS 2 012 270), bei dem am Hubtisch um waagerechte Achsen drehbare Rollen gelagert sind, die sich auf synchron angetriebenen Exzenterscheiben abstützen, so daß bei deren Umlauf eine oszillierende Bewegung des die Kokille tragenden Hubtisches entsteht, vermeidet zwar die vielen Hebel-Gelenkstellen, weil der Kokillenhub nicht mehr von Hebelgestängen übertragen wird sondern von gestängelosen Exzenterantrieben, besitzt aber wegen der zusätzlichen Hubtsichrollen andere schnell verschleissende und zu Betriebsstörungen führende Lagerstellen und Bauteile. Darüber hinaus hat der Kokillenhubtisch zur Führung der Hubbewegung mindestens einen im mittleren Bereich seitlich angebrachten Vorsprung bzw. eine Leiste, der bzw. die zwischen seitlich anliegenden Rollen geführt ist. Diese Führungsrollen, die kleinste Schwenkbewegungen machen, sind durch die geringen Winkelbewegungen einem hohen Verschleiß unterworfen, wodurch Laufgenauigkeit und -ruhe erheblich gestört sind. Im übrigen werden bei dem bekannten Antrieb dann, wenn die Kokille bzw. der Hubtisch auf einer kreisbogenförmigen Bahn oszilliert wird, Kurvenscheiben mit unterschiedlicher Exzentrizität verwendet. Hierbei ist die Exzen-trizität der bogeninneren Kurvenscheiben kleiner als die der bogenäußeren Scheiben.A known eccentric drive (DE-AS 2 012 270), in which rotatable rollers are supported on the lifting table about horizontal axes, which are supported on synchronously driven eccentric discs, so that when they rotate an oscillating movement of the mold tra The resulting lifting table avoids the many lever articulation points because the mold stroke is no longer transmitted by lever linkages but by rodless eccentric drives, but because of the additional lifting locking rollers it has other quickly wearing bearing points and components that lead to malfunctions. In addition, the mold lifting table has at least one projection or a bar which is attached laterally in the central region and which is guided between laterally adjacent rollers for guiding the lifting movement. These guide rollers, which make the smallest swivel movements, are subject to high wear due to the small angular movements, which considerably disturbs running accuracy and smoothness. Moreover, in the known drive, if the mold or the lifting table is oscillated on an arc-shaped path, cam disks with different eccentricity are used. The eccentricity of the inside of the cam disc is smaller than that of the outside of the curve.

Der Erfindung liegt somit die Aufgabe zugrunde, unter Vermeidung der störanfälligen, wartungsaufwendigen und zu Ungenauigkeiten führenden Gelenkstellen auch die Verwendung von zusätzlichen Stütz-und seitlichen Führungsrollen mit den dann erforderlichen Lagerungen iiberflüssig zu machen.The invention is therefore based on the object of avoiding the trouble-prone, maintenance-intensive and inaccurate articulation points which also make the use of additional support and lateral guide rollers with the then required bearings unnecessary.

Gemäß der Erfindung wird diese Aufgabe gelöst durch vier im Bereich der Ecken des Hubtisches angeordnete, synchron angetriebene Exzenter und mit an die Exzenter umgebenden Lagern befestigten Blattfedern zur Übertragung der Exzenterhübe auf den an den Blattfedern hängenden Hubtisch. Dabei ist jeweils eine Blattfeder mit dem Lager eines Exzenters und mit dem Hubtisch verbunden. Die durch die Exzenter bewirkten Oszillationshewegungen werden über die Blattfedern direkt auf den Hubtisch übertragen. Zusätzliche Stützrollen am Hubtisch entfallen vollkommen. Die Anzahl der Lager ist auf die Lagerstellen für die Exzenter reduziert, die zudem als problemfrei anzusehen sind, da sie als handelsübliche Pendelrollenlager ausgeführt werden können.According to the invention, this object is achieved by four synchronously driven eccentrics arranged in the region of the corners of the lifting table and with leaf springs attached to the bearings surrounding the eccentrics for transmitting the eccentric strokes to the lifting table hanging on the leaf springs. A leaf spring is connected to the bearing of an eccentric and to the lifting table. The oscillation movements caused by the eccentrics are transferred directly to the lifting table via the leaf springs. Additional support rollers on the lifting table are completely eliminated. The number of bearings is reduced to the bearing points for the eccentrics, which are also to be regarded as problem-free, since they can be designed as standard spherical roller bearings.

Für die Übertragung der Exzenterhübe auf den Hubtisch durch die Blattfedern ist es gleich, ob nach einer bevorzugten Ausgestaltung der Erfindung die Exzenter mit ihren Wellen ortsfest gelagert und die freien Enden der Blattfedern am Hubtisch festgelegt sind, oder ob in kinematischer Umkehr die freien Enden der Blattfedern ortsfest festgelegt sind und die Exzenter mit ihren Wellen auf dem Hubtisch gelagert sind. In dem ersten Fall sind die Exzenter auf einem ortsfesten Rahmen des Strangführungsgerüstes angeordnet, und in dem zweiten Fall befinden sich die Exzenter auf dem Hubtisch, d.h. ihre Lager sind in Ruhe und die Exzenterwellen führen die Exzenterhübe unter Mitnahme des Hubtisches aus, wozu in ihrem Antrieb Gelenkwellen vorgesehen werden müßten. Hierbei sind dann die freien Enden der Blattfedern mit dem ortsfesten Rahmen verbunden.For the transmission of the eccentric strokes to the lifting table by the leaf springs, it is the same whether, according to a preferred embodiment of the invention, the eccentrics are fixed in place with their shafts and the free ends of the leaf springs are fixed on the lifting table, or whether the free ends of the leaf springs are in kinematic reversal are fixed and the eccentrics with their shafts are mounted on the lifting table. In the first case, the eccentrics are arranged on a stationary frame of the strand guide frame, and in the second case, the eccentrics are on the lifting table, i.e. their bearings are at rest and the eccentric shafts carry out the eccentric strokes with the lifting table, for which purpose drive shafts would have to be provided in their drive. The free ends of the leaf springs are then connected to the stationary frame.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind den Unteransprüchen 4 bis 8 zu entnehmen, wobei insbesondere den Ansprüchen 6 bis 8 die Bedeutung zukommt, für eine bogenförmige Kokille und beim Oszillieren auf einer bogenförmigen Bahn die bis dahin bekannten seitlichen Führungsrollen durch Federelemente zu ersetzen. An den Führungsrollen wälzen sich Vorsprünge oder Leisten des Hubtisches ab, wodurch der Hubtisch auf dem Gießradius gehalten wird. Durch die erfindungsgemäß vorgeschlagenen Federstäbe ist jetzt ein Maschinenelement zur Hubtischführung und zur Aufnahme der bei der Hubbewegung auftretenden Kräfte im Einsatz, das im Dauerfestigkeitsbercich liegt und wegen des Wegfalls von Roll- und Gleitreibung unbeeinflußbar von äußeren Einwirkungen, wie z.B. Hitze und Schmutz, ist. Um beim Einbau der Federstäbe keine Durchbiegung der Stäbe zuzulassen, kann es vorteilhaft sein, die Stäbe hydraulisch vorzuspannen.Further advantageous refinements of the inventive concept can be found in subclaims 4 to 8, claims 6 to 8, in particular, being of importance for replacing the previously known lateral guide rollers by spring elements for an arcuate mold and when oscillating on an arcuate path. Projections or strips of the lifting table roll on the guide rollers, as a result of which the lifting table is held on the casting radius. Due to the spring rods proposed according to the invention, a machine element for lifting table guidance and for absorbing the forces occurring during the lifting movement is now in use, which lies in the fatigue strength range and, due to the elimination of rolling and sliding friction, cannot be influenced by external influences, such as e.g. Heat and dirt, is. In order not to allow any deflection of the rods when installing the spring rods, it can be advantageous to preload the rods hydraulically.

Die Seitenansicht nach Fig. 1 läßt den oberen Teil einer Stranggießanlage erkennen, die mit dem erfindungsgemäßen Kokillen-Hubsystem / ausgerüstet ist. Das mit dem nicht dargestellten Fundament des Hüttenflurs verankerte Grundgerüst 1 trägt die die Stützrollen 2 für den Strang aufnehmenden Segmente, von denen lediglich die beiden obersten Segmente 4, 5 abgebildet sind. Zwischen dem obersten Segment 4 und einem ortsfesten, mit dem Grundgerüst 1 in Verbindung stehenden Rahmen 8 befindet sich der bewegliche Hubtisch 9, auf welchem die Kokille 10 aufsitzt. Der Hubtisch 9 hängt hierbei an vier im Bereich der Ecken des Hubtisches angreifenden Blattfedern 11, die jeweils mit einem Ende an hochgezogenen Stützen 8a des ortsfesten Rahmens B mit den Aussenlagern 12 von Exzentern 13 und an dem anderen, sozusagen freien Ende mit dem Hubtisch 9 verbunden sind (Fig. 4 und Fig. 5). Die Verbindung kann z.B. mittels Bolzen 14, 14a, 14b hergestellt werden.1 shows the upper part of a continuous caster, which is equipped with the mold lifting system / according to the invention. The basic structure 1 anchored to the foundations of the foundry corridor does not support the segments 2 which hold the support rollers 2 for the strand, of which only the two uppermost segments 4, 5 are shown. Between the uppermost segment 4 and a stationary frame 8, which is connected to the basic structure 1, there is the movable lifting table 9, on which the mold 10 is seated. The lifting table 9 is suspended from four leaf springs 11 which engage in the corners of the lifting table, each of which is connected at one end to raised supports 8a of the fixed frame B with the outer bearings 12 of eccentrics 13 and at the other, free end, so to speak, of the lifting table 9 are (Fig. 4 and Fig. 5). The connection can e.g. can be produced by means of bolts 14, 14a, 14b.

Der Antrieb der Exzenter 13 erfolgt von einem Motor 15 über Winkelgetriebe 16 und hellen 19 (Fig. 3), wobei die Wellen synchron laufen. Die Exzenterwellen 19 sind in Lagern 18 auf den Stützen 8a des ortsfesten Rahmens 8 gelagert, und beim Betätigen des Motors 15, in dessen Ausgangswelle 20 noch eine Kupplung 21 zwischengeschaltet ist, werden die Exzenterhübe von den Blattfedern 11, die die Verbindung zwischen dem ortsfesten Rabmen 8 und dem beweglichen Hubtisch 9 herstellen, auf den Hubtisch übertragen, so daß die Kokille die gewünschte Aufand Abwärtsbewegung ausführt.The eccentrics 13 are driven by a motor 15 via angular gears 16 and bright 19 (FIG. 3), the shafts running synchronously. The eccentric shafts 19 are mounted in bearings 18 on the supports 8a of the fixed frame 8, and when the motor 15 is actuated, in the output shaft 20 of which a clutch 21 is also interposed, the eccentric strokes are made by the leaf springs 11 which establish the connection between manufacture the stationary rabmen 8 and the movable lifting table 9, transfer them to the lifting table, so that the mold executes the desired up and down movement.

die aus Fig. 4 und 5 entnommen werden kann, ist jede Blattfeder uber ein lösbares Anschlußstück 22 mit dem jeweiligen Exzenterlager 12 verbunden, wobei die Anschlußstücke 22 unter Zwischenlage von Distanzblechen 23 über die Schrauben 14a mit den Lagern 12 zusammengefügt sind. Zur Justierung des Hubtisches 9 brauchen nur die Bolzen 14a etwas gelöst zu werden, da die Distanzbleche 23, die beim Anziehen der Schrauben geklemmt werden, und somit von den Schrauben nicht durchgriffen sind quer zu den Schrauben 14a entnommen und durch andere Distanzbleche mit gewünschter Dickenabmessung ersetzt werden können (Fig. 4). Die Festlegung der nicht an den Lagern 12 der Exzenter 13 angreifenden freien Enden der Blattfedern 11 mit dem Hubtisch 9 erfolgt ebenfalls unter Einbeziehung eines Zwischenstückes 24, das mit dem Hubtisch 9 über Schrauben 14b und mit der Blattfeder 11 über die Bolzen 14 die Verbindung herstellt (Fig. 5).4 and 5 can be seen, each leaf spring is connected to the respective eccentric bearing 12 via a detachable connecting piece 22, the connecting pieces 22 being joined to the bearings 12 with the interposition of spacer plates 23 via the screws 14a. To adjust the lifting table 9, only the bolts 14a need to be loosened somewhat, since the spacer plates 23, which are clamped when the screws are tightened and are therefore not penetrated by the screws, are removed transversely to the screws 14a and replaced by other spacer plates with the desired thickness dimension can be (Fig. 4). The fixing of the free ends of the leaf springs 11 not acting on the bearings 12 of the eccentrics 13 with the lifting table 9 also takes place with the inclusion of an intermediate piece 24 which establishes the connection with the lifting table 9 via screws 14b and with the leaf spring 11 via the bolts 14 ( Fig. 5).

Soll die Kokille 10 beim Oszillieren auf einer bogenförmigen Bahn bewegt werden, muß der Hubtisch 9 mit einer entsprechenden Radiusführung versehen sein. Außer der bekannten Unterschiedlichkeit der Exzenter - die nach Fig. 3 in Pfeilrichtung gesehen bogeninneren Exzenter 12 haben eine kleinere Exzentrizität e1 wie die bogenäußeren Exzenter 12 mit der Exzentrizität e2 - weisen deshalb die Schmalseiten des Hubtisches neuartige Führungen auf, die in Fig. 6 allgemein mit 25 bezeichnet sind. Die Anordnung dieser Führungen 25 ist aus Fig. 2 ersichtlich. Sie bestehen aus als Rundstäbe ausgebildeten Federelementen 25a, von denen jeweils die äußeren Enden an dem ortsfesten Rahmen 8 verankert sind, während die mittleren Bereiche an winkelförmigen Leisten 26, 26a festgelegt sind, die sich in der Mitte an den Schmalseiten des Hubtisches 9 befinden. Es empfiehlt sich, mehrere Federstäbe 25a i nebeneinanderliegend vorzusehen. Zur Aufnahme der Führungs- und Gegenkräfte müssen die Federstäbe in Einbaulage in Richtung zum Mittelpunkt des Gießradius der Stranggießanlage ausgerichtet sein. Jeder Federstab 25a kann auch anstatt aus einem einheitlichen Federstab aus einem Paar von Federstäben bestehen, wobei dann die inneren Enden eines jeden Federstabes an den Leisten 26, 26a festgelegt sind.If the mold 10 is to be moved on an arcuate path during oscillation, the lifting table 9 must be provided with a corresponding radius guide. In addition to the known diversity of the eccentrics - the eccentrics 12 inside the bend seen in the direction of the arrow in FIG. 3 have a smaller eccentricity e1 than the eccentric eccentric 12 with the eccentricity e2 - the narrow sides of the lifting table therefore have novel guides, which are generally shown in FIG. 6 25 are designated. The arrangement of these guides 25 can be seen in FIG. 2. They consist of spring elements 25a designed as round rods, of which the outer ends are anchored to the stationary frame 8, while the central regions are fixed to angular strips 26, 26a, which are located in the middle on the narrow sides of the lifting table 9. It is advisable to provide several spring bars 25a i side by side. To absorb the guiding and counter forces, the spring bars must be installed in the direction of The center of the casting radius of the continuous caster must be aligned. Each spring bar 25a can also consist of a pair of spring bars instead of a single spring bar, in which case the inner ends of each spring bar are fixed to the strips 26, 26a.

Die Federatäbe 25a sind als komplette Einheit leicht montierbar. Dazu werden die Federstabenden von Blöcken 29, 30 aufgenommen, welche auf eine Trägerplatte 31 aufgesetzt und mit dieser z.B. verschweißt sind. Im mittleren Bereich besitzen die Federstäbe jeweils eine Wulst 32 (Fig. 8), die in entsprechenden Ausnehmungen 33 der Leisten 26, 2Ga passen, die/dem Zusammenfügen, wodurch die Wulste 32 in den Ausnehmungen 33 zentriert werden, durch Schrauben 34 miteinander verbunden werden. Beim Einbau wird dann an den beiden Schmalseiten der Kokille je ein Leistenpaar 26, 26a an den beweglichen Hubtisch 9 mittels Schrauben 35 angeschraubt, während die Trägerplatte 31 ebenfalls durch Schrauben 36 mit dem ortsfesten Rahmen 8 verschraubt wird. Als Montagehilfe können die Leisten durch eine Zwischenlage 39 unterstützt werden, die nach dem Verschrauben wieder entfernt wird. Sobald der Oszillationsantrieb in Bewegung gesetzt wird, führen die zum Mittelpunkt ausgerichteten Federstäbe 25a den Hubtisch auf der gewünschten bogenförmigen Bahn, wobei sie etwas gedehnt werden. Es empfiehlt sich, die Federstäbe 25a über äußere Muttern 40 (Fig. 8) vorzuspannen.The spring rods 25a are easy to assemble as a complete unit. For this purpose, the spring rod ends are received by blocks 29, 30, which are placed on a carrier plate 31 and welded to it, for example. In the central region, the spring rods each having a bead 32 (Fig. 8) that fit into corresponding recesses 33 of the strips 26, 2Ga, the / the joining, whereby the beads are centered in the recesses 32, 33 interconnected by screws 34 . During installation, a pair of strips 26, 26a is then screwed to the movable lifting table 9 by means of screws 35 on the two narrow sides of the mold, while the carrier plate 31 is also screwed to the fixed frame 8 by screws 36. As an assembly aid, the strips can be supported by an intermediate layer 39, which is removed again after screwing. As soon as the oscillation drive is set in motion, the spring bars 25a aligned with the center point guide the lifting table on the desired arcuate path, whereby they are somewhat stretched. It is advisable to pretension the spring bars 25a via outer nuts 40 (FIG. 8).
