Description

Die Erfindung bezieht sich auf ein Walzgerüst mit zwei oder mehr Paaren von Walzenständern mit zwischen den Ständern der Paare geführten Walzenlagerträgern (Walzeneinbaustücken) und diese Ständer außerhalb der Walzenlagerträger verbindende Quertraversen, die über Druckmittelträger mit antreibbaren, auf ortsfesten in die Ständer eingesetzten, auf diesen aufstehenden Gewindesäulen geführten Druckmuttern auf den Gewindesäulen anstellverschiebbar sind.The invention relates to a roll stand with two or more pairs of roll stands with roll bearing supports (roll chocks) guided between the stands of the pairs, and cross members connecting these stands outside the roll bearing supports, which are driven by pressure medium supports with drivable, fixed in the stands, standing on them Threaded pillars are adjustable adjustable on the threaded pillars.

Bei einem als Universalwalzgerüst ausgebildeten Walzgerüst dieser Gattung (DE-A-1 452 027) wurden die Druckmutterträger für die Bewegung, d.h. die Anstellung des Walzlagerträgers für die Vertikalwalzen auf die ortsfest in die Walzenständer eingesetzten Gewindespindeln aufgesetzt, und die in diesen Trägern angeordneten Druckmuttern mit den Gewindespindeln gewindeverbunden. Der Antrieb der Druckmuttern der Druckmutterträger erfolgte von außerhalb der Träger angeordneten Antriebsaggregaten aus über eine Gelenkspindelverbindung. Eine entsprechende Anordnung für die Anstellung der Horizontalwalzen war bei dieser Gerüstausbildung nicht vorhanden; die Horizontalwalzen wurden hier in üblicher Weise über eine in einer fest mit dem Walzenständer verbundenen Kappe gewindegelagerte Anstellspindel angestellt.In the case of a roll stand of this type (DE-A-1 452 027) designed as a universal roll stand, the pressure nut carriers for the movement, that is to say the employment of the roller bearing support for the vertical rolls, were placed on the threaded spindles fixedly installed in the roll stand, and the pressure nuts arranged in these supports were also included the threaded spindles. The pressure nuts of the pressure nut carriers were driven from drive units arranged outside the carriers via a joint spindle connection. A corresponding arrangement for the employment of the horizontal rollers was not available with this stand design; the horizontal rollers were adjusted here in the usual way via an adjusting spindle which was threadedly mounted in a cap firmly connected to the roller stand.

Diese Walzgerüstausbildung mit Anstellung der Träger der Vertikalwalzen über unabhängig von diesen auf die Gewindespindeln aufgesetzte Druckmutterträger sollte einmal den sonst üblichen, an die Ständer für die Führung der Horizontalwalzen seitlich angesetzten Tragansatz für die Vertikalwalzenträger vermeiden und weiter das Auswechseln dieser Vertikalwalzen mit ihrem Träger erleichtern, sowie ferner die Möglichkeit schaffen, bei Duo-Walzbetrieb nur mit den Horizontalwalzen auch Horizontalwalzen mit kleinerem als dem üblichen Durchmesser zu verwenden.This roll stand design with employment of the supports of the vertical rolls via pressure nut supports placed independently of these on the threaded spindles should, on the one hand, avoid the otherwise usual support attachment for the vertical roll supports attached laterally to the stands for guiding the horizontal rolls and further facilitate the replacement of these vertical rolls with their supports, as well as also create the possibility to use horizontal rolls with a smaller than the usual diameter in duo rolling operation only with the horizontal rolls.

Der Erfindung liegt die Aufgabe zugrunde, diese bekannte Walzgerüstausbildung weiter zu verbessern, um auch den leichteren Ausbau der Horizontalwalzen nach der Seite oder bei Walzgerüsten mit ausschwenkbarer oberer, die beiden Walzenständer verbindender Quertraverse einen Ausbau der Horizontalwalzensätze nach oben, sowie eine voneinander unabhängige Anstellung beider Horizontalwalzen möglich zu machen. Diese Aufgabe wird ausgehend von einen Walzgerüst nach den Oberbegriff des Anspruchs 1 durch eine parallel oder quer zu der jeweiligen Quertraverse an deren dem Walzenlagerträger abgewandten Seite auf beide Gewindesäulen aufgesetzte Zusatz-Quertraverse und mit dieser verbundene, mit den Druckmuttern der Druckmutterträger kuppelbaren Antriebselemente und Antriebe gelöst. Die Zusatzquertraversen können erfindungsgemäß ortsfest oder bewegbar auf den Gewindesäulen angeordnet werden, wobei auf den Gewindesäulen gelagerte, von den Antriebselementen antreibbare Getriebemuttern mit den Druckmuttern kuppelbar sein, und bei Walzgerüsten mit ortsfest angeordneten Zusatz-Quertraversen die Getriebemuttern als axial verzahnte Schiebekupplungen ausgebildet mit den Druckmuttern antriebsverbindbar sein. Bei Walzgerüsten mit um eine der Längsachsen der Gewindesäulen schwenkbaren Quertraversen können die Zusatz-Quertraversen ebenfalls um die Längsachsen der Gewindesäulen schwenkbar ausgebildet werden. Schließlich können erfindungsgemäß die Druckmuttern lösbar mit den Quertraversen verbunden sein und in deren ausgeschwenktem Zustand mit der jeweiligen Gewindesäule schraubverbunden bleiben.The invention is based on the object of further improving this known roll stand design, in order to also facilitate the removal of the horizontal rolls to the side or, in the case of roll stands with a swiveling upper cross bar connecting the two roll stands, an expansion of the horizontal roll sets upwards and an independent employment of both horizontal rolls to make possible. This object is achieved on the basis of a rolling stand according to the preamble of claim 1 by an additional crossbar placed parallel or transversely to the respective crossbar on its side facing away from the roller bearing support on both threaded columns and connected to this, drive elements and drives which can be coupled to the pressure nuts of the pressure nut support . According to the invention, the additional crossbeams can be arranged in a stationary or movable manner on the threaded columns, gearbox nuts mounted on the threaded columns and drivable by the drive elements being able to be coupled to the pressure nuts, and in the case of rolling stands with fixedly arranged additional crossbeams, the geared nuts are designed as axially toothed sliding couplings with the pressure lock nuts be. In the case of rolling stands with cross beams that can be swiveled around one of the longitudinal axes of the thread columns, the additional cross beams can be used are also designed to be pivotable about the longitudinal axes of the threaded columns. Finally, according to the invention, the pressure nuts can be releasably connected to the crossbeams and can remain screw-connected to the respective threaded column in their swung-out state.

Der Ausbau von Horizontalwalzensätzen mit den Walzenlagerträgern ist je nach der Ausbildungsform bei ausgeschwenkter Quertraverse (DE-A1-30 39 203) nach oben oder bei entsprechend weit nach oben bzw. nach unten gefahrenen Quertraversen auch nach der Seite hin möglich. Die oberen und die unteren Horizontalwalzen lassen sich hierbei unabhängig voneinander anstellen, und es besteht auch die Möglichkeit, über die Anstellung der unteren Horizontalwalzen die Gerüsthöhe zu verstellen. Da die Walzenständer selbst verhältnismäßig klein gehalten werden können, entsteht ein entsprechend kleiner und mit wenig Aufwand herzustellender Walzgerüstkörper, der mit ggfs. untereinander identischen Quertraversen auch für die Vertikalwalzen und Zusatz-Quertraversen mit aufsetzbaren einfachen Serienmotoren als Antriebsaggregaten ausgestattet werden kann, wodurch sich der Herstellungsaufwand zusätzlich verringert. Die Walzenständer stellen insb. bei Universalwalzgerüsten, verglichen mit der üblichen Ausbildungsform kleine unkomplizierte Gußteile dar. Bei Verwendung kleiner Walzen für das Walzgut kleiner Querschnitte entsteht praktisch ein Walzgerüst mit sehr großer Ständersteifigkeit und hoher Toleranzgenauigkeit, weil in diesem Falle die Quertraversen alle sehr nahe an den die Gewindesäulen tragenden Ständerteil herangefahren werden können und damit kurze Ständerlängen entstehen, weil die überstehenden Längen der Gewindesäulen sich außerhalb des Belastungsrahmens des Walzgerüstes befinden.The expansion of horizontal roller sets with the roller bearing supports is possible, depending on the design, with the cross-beam swung out (DE-A1-30 39 203) upwards or with the cross-beams moved correspondingly upwards or downwards to the side. The upper and lower horizontal rollers can be adjusted independently of one another, and there is also the possibility of adjusting the stand height by adjusting the lower horizontal rollers. Since the roll stands themselves can be kept relatively small, a correspondingly small and inexpensive roll stand body is created, which can be equipped with cross-beams that are possibly identical to one another, also for the vertical rolls and additional cross-beams, with attachable simple series motors as drive units, which increases the manufacturing outlay additionally reduced. In the case of universal roll stands, the roll stands are small, uncomplicated castings compared to the usual design. When using small rolls for the rolling stock with small cross-sections, a roll stand with a very high stiffness and high tolerance accuracy is created, because in this case the crossbeams are all very close to the the column part supporting the threaded column can be moved up and thus short column lengths arise because the protruding lengths of the threaded columns are outside the load frame of the roll stand.

Die Getriebemuttern 30, 31 werden von auf den Zusatz-Quertraversen 26, 27 bzw. 28, 29 angeordneten Motoren 32 und Anordnungen von Gelenkkupplungen 33 gemeinsam angetrieben und übertragen die Antriebskräfte auf die in den Quertraversen 17, 18 bzw. 19, 20 lagernden Druckmuttern 21, 22 bzw. 23, 24.Upper crossbars 17, 18 and lower crossbars 19, 20 are slidably mounted on the pairs of threaded columns 1a and 2a (FIGS. 1 and 2), into which rotatably mounted pairs of pressure nuts 21, 22 and 23, 24 are inserted which are in screw connection with the threaded columns 1a, 2a or 3a, 4a. Above and below the crossbars 17, 18 and 19, 20, respectively, upper additional crossbars 26, 27 and lower additional crossbars 28, 29 are arranged on the pairs of threaded columns 1a, 2a and 3a, 4a. In the exemplary embodiment, these each lie transversely to the upper crossbeams 17, 18 and the lower crossbeams 19, 20 and are screw-connected to the threaded columns 1a, 2a and 3a, 4a by means of pairs of gear nuts 30 and 31 which are mounted in them (cf. 1 bottom right). The gear nuts 30, 31 are jointly driven by motors 32 and arrangements of articulated couplings 33 arranged on the additional crossbeams 26, 27 and 28, 29, respectively, and transmit the drive forces to the pressure nuts 21 mounted in the crossbeams 17, 18 and 19, 20 , 22 and 23, 24 respectively.

Wie aus Fig. 1, 2, 4 und 5 ersichtlich, weisen die Tragrahmen 13 bzw. 14 der Walzen des Vertikalwalzenpaares 16 Auflageflächen 13a auf, an die sich Druckmuttern 34 bzw. 35 abstützen. Die Tragrahmen 13 bzw. 14 bilden auf diese Weise jeweils Quertraversen, die anders als die oberen und unteren Zusatz-Traversen 26, 27 bzw. 28, 29 mit den Gewindesäulenpaaren 7a bzw. 8a nicht schraubverbunden sind, sondern von den Druckmuttern 34 bzw. 35, die hier in den Zusatz-Quertraversen 36, 37 selbst lagern, auf den Gewindesäulen 7a bzw. 8a verschiebbar sind. Die Druckmuttern 34 bzw. 35 werden von Getriebemuttern 38, 39 angetrieben, die in den Zusatz-Quertraversen 36 bzw. 37 angeordnet sind. Der Antrieb dieser Getriebemuttern 36, 37 erfolgt entsprechend wie bei den Zusatz-Quertraversen 26, 27 bzw. 28, 29 durch Motoren 40 über Anordnungen von Gelenkkupplungen 41. Die Mittenachse dieser Gelenkkupplungen 41 verläuft zwischen benachbarten Motoren 40 Fig. 3) geneigt zur Horizontalen.As can be seen from FIGS. 1, 2, 4 and 5, the support frames 13 and 14 of the rollers of the pair of vertical rollers 16 have support surfaces 13a on which pressure nuts 34 and 35 are supported. In this way, the support frames 13 and 14 each form crossbeams which, unlike the upper and lower additional crossbeams 26, 27 and 28, 29, are not screw-connected to the pairs of threaded columns 7a and 8a, but rather by the pressure nuts 34 and 35 , which are stored in the additional crossbeams 36, 37 themselves, are displaceable on the threaded columns 7a and 8a. The pressure nuts 34 and 35 are driven by gear nuts 38, 39 which are arranged in the additional cross members 36 and 37, respectively. The drive of these gear nuts 36, 37 takes place correspondingly as with the additional crossbeams 26, 27 and 28, 29 by motors 40 via arrangements of articulated couplings 41. The central axis of these articulated couplings 41 runs between adjacent motors 40 (FIG. 3) inclined to the horizontal.

Die Antriebsübertragung von den Getriebemuttern 30, 31 bzw. 38, 39 auf die Druckmuttern 21, 22, 23, 24 bzw. 34, 35 erfolgt entweder direkt (Fig. 2), wobei die Getriebemuttern 30, 31 bzw. 38, 39 ebenfalls mit den zugehörigen Gewindesäulen 1a, 2a, 3a, 4a bzw. 7a, 8a schraubverbunden sind oder daß sie auf deren Enden lagern und mit den zugehörigen Druckmuttern 21, 22 bzw. 23, 24 über axial verzahnte Schiebekupplungen 30a, 31a verbunden sind (Fig. 1).The drive transmission from the gear nuts 30, 31 and 38, 39 to the pressure nuts 21, 22, 23, 24 and 34, 35 takes place either directly (FIG. 2), the gear nuts 30, 31 and 38, 39 also with the associated threaded columns 1a, 2a, 3a, 4a or 7a, 8a are screw-connected or that they are supported on their ends and connected to the associated pressure nuts 21, 22 or 23, 24 via axially toothed sliding couplings 30a, 31a (Fig. 1 ).

Die oberen Quertraversen 17, 18 ruhen mit seitlichen Tragansätzen 42 auf Druckstößeln 43 von an den Doppelsäulenständern 1, 2 angeordneten Kolben-Zylinder-Aggregaten 44 (Fig. 2 und 3), während die Walzentraglager 9 der oberen Horizontalwalze 15 an den Kolbenstangen 45 von Kolben-Zylinder-Aggregaten 46 hängen, die ihrerseits aushebbar an an den Quertraversen 17, 18 angeordneten Tragansätzen 47 hängen. Die oberen und unteren Quertraversen 17, 18 bzw. 19, 20 weisen Druckansätze 17a, 18a bzw. 19a, 20a auf, die die Walzlagerträger 9 bzw. 10 der oberen und der unteren Horizontalwalzen beaufschlagen.The upper crossbeams 17, 18 rest with lateral support lugs 42 on pressure tappets 43 of piston-cylinder units 44 (FIGS. 2 and 3) arranged on the double column stands 1, 2, while the roller support bearings 9 of the upper horizontal roller 15 on the piston rods 45 of pistons Cylinder units 46 hang, which in turn hang from the lifting attachments arranged on the crossbeams 17, 18, 47. The upper and lower crossbeams 17, 18 and 19, 20 have pressure attachments 17a, 18a and 19a, 20a, which act on the roller bearing supports 9 and 10 of the upper and lower horizontal rolls.

Die oberen Horizontalführungen 48 für das Walzgut sind in bekannter Weise gelenkig in Lagerböcke 49 eingehängt, die mittels Tragplatten 50 mit der der oberen Quertraverse 17, 18 verbunden sind, während die unteren Horizontalführungen 51 gelenkig auf Lagerböcke 52 aufgesetzt sind, die entsprechend auf Tragplatten 60 sitzen, die mit der unteren Quertraverse 19 verbunden sind. Die Vertikalführungen 53 für das Walzgut (vgl. Fig. 3 und 4) sind in ebenfalls an sich bekannter Weise einerseits an den Walzlagerträger 54 mit einem Lenklager 53a und andererseits mit einem weiteren Lenklager 53b an einer am Seitenführungsansatz 7 bzw. 8 des Walzgerüstes angeordneten Führung 55 geführten Stoßstange 56 angelenkt, deren freies Ende fest mit dem Tragrahmen 13 bzw. 14 des Walzentraglagers 54 verbunden ist. An den Seitenführungsansätzen 7 bzw. 8 sind ferner Kolben-Zylinder-Aggregate 58 mit Schubstößeln 57 angeordnet, die die den Druckmuttern 34 bzw. 35 abgewandte Seite des Tragrahmens 13 bzw. 14 beaufschlagen.The upper horizontal guides 48 for the rolling stock are hinged in a known manner in bearing blocks 49, which are connected by means of support plates 50 to that of the upper crossmember 17, 18, while the lower horizontal guides 51 are articulated on bearing blocks 52, which are correspondingly seated on support plates 60 , which are connected to the lower crossbar 19. The vertical guides 53 for the rolling stock (see FIGS. 3 and 4) are likewise in a manner known per se on the one hand on the roller bearing support 54 with a steering bearing 53a and on the other hand with a further steering bearing 53b on a guide arranged on the side guide shoulder 7 or 8 of the rolling stand 55 guided bumper 56 articulated, the free end fixed to the support frame 13 or 14th of the roller bearing 54 is connected. On the side guide lugs 7 and 8 there are also piston-cylinder units 58 with push rods 57 which act on the side of the support frame 13 and 14 facing away from the pressure nuts 34 and 35, respectively.

Die Walzentraglager 9 und 10 der Horizontalwalzen 15 werden über die Druckansätze 17a, 18a bzw. 19a, 20a der Quertraversen 17, 18 bzw. 19, 20 von oben bzw. von unten beaufschlagt und in Anstellrichtung bewegt, wenn die Motoren 32 der zugehörigen Zusatz-Quertraversen 26, 27 bzw. 28, 29 die Druckmuttern 21, 22 bzw. 24, 25 über die Getriebemuttern 30, 31 antreiben. Die Zusatz-Quertraversen 26, 27 bzw. 28, 29 folgen dabei der Bewegung der Quertraversen 17, 18 bzw. 19, 20 in Anstellrichtung synchron; sie können aber auch ortsfest in einer oberen Stellung verbleiben, wenn die Getriebemuttern 30a, 31a, wie beschrieben (Fig. 1), auf den Enden der Gewindesäulen 1a, 2a bzw. 3a, 4a drehgelagert sind und die Antriebskraft über axial verzahnte Schiebekupplungen 30a, 31a auf die Druckmuttern 21, 22 bzw. 23, 24 übertragen wird. Die Ausbalancierung der oberen Horizontalwalze 15 mit ihren Walzenlagerträgern 9 und 10 gegenüber den Quertraversen 17, 18 erfolgt dabei mit Hilfe der Kolben-Zylinder-Aggregate 46, während die Druckstößel 43 der Kolben-Zylinder-Aggregate 44 die Quertraversen 17, 18 bei ihren Bewegungen in beiden Anstellrichtungen stützend tragen.The roller support bearings 9 and 10 of the horizontal rollers 15 are acted upon from above or below by the pressure attachments 17a, 18a or 19a, 20a of the crossbeams 17, 18 or 19, 20 and moved in the direction of attack when the motors 32 of the associated additional Cross beams 26, 27 and 28, 29 drive the pressure nuts 21, 22 and 24, 25 via the gear nuts 30, 31. The additional crossbeams 26, 27 and 28, 29 follow the movement of the crossbeams 17, 18 and 19, 20 synchronously in the direction of attack; but they can also remain stationary in an upper position if the gear nuts 30a, 31a, as described (FIG. 1), are rotatably mounted on the ends of the threaded columns 1a, 2a or 3a, 4a and the driving force is via axially toothed sliding clutches 30a, 31a is transmitted to the pressure nuts 21, 22 and 23, 24, respectively. The upper horizontal roller 15 with its roller bearing supports 9 and 10 are balanced with respect to the crossbeams 17, 18 by means of the piston-cylinder units 46, while the pressure rams 43 of the piston-cylinder units 44 move the crossbeams 17, 18 during their movements support both directions of support.

Die Bewegung der beiden, die Vertikalwalze 16 tragenden Tragrahmen 13, 14 in den Abstellrichtungen wird (Fig. 4 und 5) mit Hilfe der auf den Zusatz-Quertraversen 36, 37 angeordneten und gelagerten Druckmuttern 34, 35 hervorgerufen, wobei diese, da sie in ihren Stirnflächen nur auf den Auflageflächen 13a bzw. 14a der Tragrahmen 13, 14 aufliegen, diese nur in Richtung auf das Walzgut hin anzutreiben vermögen, während die Bewegungen in entgegengesetzter Richtung durch die Schubstößel 57 bewirkt wird. Die Vertikalführungen 53 für das Walzgut folgen diesen Bewegungen infolge ihrer Anlenkung bei 53a an den Walzlagerträger 54 der Vertikalwalze 16 und 53b an die mit dem jeweiligen Tragrahmen 13, 14 verbundenen Stoßstange 56.The movement of the two supporting frames 13, 14 carrying the vertical roller 16 in the storage directions (FIGS. 4 and 5) is brought about with the aid of the pressure nuts 34, 35 arranged and mounted on the additional crossbeams 36, 37, this being because they are in their end faces rest only on the support surfaces 13a and 14a of the support frames 13, 14, which can only drive them in the direction of the rolling stock, while the movements in the opposite direction are effected by the push rod 57. The vertical guides 53 for the rolling stock follow these movements as a result of their articulation at 53a on the roller bearing support 54 of the vertical roll 16 and 53b on the bumper 56 connected to the respective support frame 13, 14.

Wie in Fig. 4 angedeutet, können die oberen Quertraversen 17 und 18 aus einer in vollen Linien dargestellten Arbeitslage (Quertraversen 17) in eine, das Ausbauen der Horizontalwalzen 15 mit ihren Walzlagerträgern 9, 10 nach oben erlaubende, strichpunktiert wiedergegebene Ausbaustellung (Quertraverse 18) geschwenkt werden. Die zugehörigen Druckmuttern 21, 22 verbleiben dabei auf den Gewindesäulen 1a, 2a. Der Ausbau der Horizontalwalzen 15 nach oben bspw. mit Hilfe eines Krans wird dabei durch die zugehörigen Zusatz-Quertraversen 26, 27 nicht gehindert, weil diese erfindungsgemäß quer zu den Quertraversen 17, 18 liegen.As indicated in FIG. 4, the upper crossbeams 17 and 18 can be moved from a working position shown in full lines (crossbeams 17) into a dismantled position (crossbeam 18) that allows the horizontal rollers 15 with their roller bearing supports 9, 10 to be removed upwards. be pivoted. The associated pressure nuts 21, 22 remain on the threaded columns 1a, 2a. The removal of the horizontal rollers 15 upwards, for example with the aid of a crane, is not prevented by the associated additional crossbeams 26, 27, because according to the invention these are transverse to the crossbeams 17, 18.

In ähnlicher Weise können (vgl. Fig. 3 und 4) die die Vertikalwalze 16 aufnehmenden Tragrahmen 13, 14 ausgebaut werden. Diese lassen sich ebenfalls bspw. mit Hilfe eines Krans senkrecht nach oben von den Gewindesäulen 7a, 8a abheben, wobei sich noch der besondere Vorteil ergibt, daß dabei auch die Seitenführungen 53 für das Walzgut an den jeweiligen Tragrahmen 13, 14 verbleiben können. Der zur Horizontalen geneigte Verlauf der Mittenachse der Gelenkkupplungsanordnung 41 zwischen den Motoren 40 (vgl. Fig. 3) erlaubt es, die Zusatz-Quertraversen 36, 37 auch im Bereich der auf den Zapfen des Horizontalwalzenpaares 15 sitzenden Antriebskuppelhülsen 60 zu bewegen, ohne von deren Umfang behindert zu werden.In a similar manner (see FIGS. 3 and 4), the support frame 13, 14 receiving the vertical roller 16 can be removed. These can also be lifted vertically upward from the threaded columns 7a, 8a, for example with the aid of a crane, with the particular advantage that the side guides 53 for the rolling stock can also remain on the respective support frames 13, 14. The horizontal inclination of the center axis of the articulated coupling arrangement 41 between the motors 40 (see FIG. 3) makes it possible to move the additional crossbeams 36, 37 also in the area of the drive coupling sleeves 60 seated on the pins of the pair of horizontal rollers 15, without the latter Extent to be hindered.

Je nach den betriebsmäßigen und konstruktiven Erfordernissen können bei Walzgerüsten der erläuterten Art auch Quertraversen verwendet werden, auf denen die Antriebselemente für die Druckmuttern direkt angeordnet sind; ebenso besteht die Möglichkeit, die beim beschriebenen Ausführungsbeispiel bei den Zusatz-Quertraversen für die Tragrahmen der Vertikalwalzen verwendete Lagerung der Druckmuttern in der Zusatz-Quertraverse auch bei den Zusatz-Quertraversen für die die Horizontalwalzen beaufschlagenden Quertraversen zu verwenden. Entsprechendes gilt für die Ausbildung der Getriebemuttern als axial verzahnte Schiebekupplung; die Getriebemuttern können dabei sowohl als mit einer Schiebekupplung verbundenes Schneckenrad zweiteilig als auch einstückig ausgebildet sein.Depending on the operational and design requirements, cross-beams can also be used in roll stands of the type described, on which the drive elements for the pressure nuts are arranged directly; there is also the possibility of using the mounting of the pressure nuts in the additional crossbeam used in the exemplary embodiment described for the additional crossbeams for the supporting frame of the vertical rollers, also for the additional crossbeams for the crossbeams acting on the horizontal rollers. The same applies to the design of the gear nuts as an axially toothed sliding clutch; the gear nuts can be designed in two parts as well as in one piece both as a worm wheel connected to a sliding clutch.
