Description

Die Erfindung bezieht sich auf eine Walzenstraße mit den Merkmalen nach den Oberbegriffen der Ansprüche 1 + 2; siehe beispielsweise EP-A 0 154 249.The invention relates to a roller train with the features according to the preambles of claims 1 + 2; see for example EP-A 0 154 249.

Es ist die Aufgabe der Erfindung eine Walzenstraße dieser Art so auszubilden, daß der Dimensionswechsel der Walzen mit geringstem Zeitaufwand durchgeführt werden kann.It is the object of the invention to design a roller train of this type in such a way that the dimension change of the rollers can be carried out in the shortest possible time.

Diese Aufgabe wird nach dem gleichen Lösungsprinzip durch Walzenstraßen mit den Merkmalen des Anspruchs 1 oder des Anspruchs 2 gelöst. Die weiteren Unteransprüche haben bevorzugte Weiterbildungen dieser Lösungen zum Inhalt.This object is achieved according to the same solution principle by roller mills with the features of claim 1 or claim 2. The further subclaims contain preferred developments of these solutions.

Walzenstraßen nach der Erfindung haben den Vorteil, daß bei jeder Ausführungsform sämtliche hinteren, also antriebsseitigen Ständer am Maschinenbett bleiben können, wenn ein Dimensionswechsel der Walzen durchgeführt wird. Dies vereinfacht den konstruktiven Aufbau. Das Spannen bzw. Entspannen der Walzenachsen bzw. der Zentrierbolzen erfolgt in einfacher Weise von Hand mittels eines Inbusschlüssels. Durch die hydraulische Verspannung ergibt sich eine hohe Rundlaufgenauigkeit. Bei der Ausführungsform nach Anspruch 1, können sämtliche vorderen Ständer, da sie zu einer Einheit zusammengefaßt sind, nach oben abgehoben werden, so daß für die Abnahme voderseitig kein Raum zur Verfügung zu sein braucht. Ein Lösen von Schraubverbindungen ist beim Wechsel nicht erforderlich. Durch die kraftschlüssige Verbindung der vorderen und der hinteren Ständer ergibt sich eine große Laufruhe. Paßfedernuten in den Walzenachsen entfallen.Rolling mills according to the invention have the advantage that, in each embodiment, all rear stands, that is to say the drive-side stands, can remain on the machine bed when the rolls are changed in dimension. This simplifies the construction. The roller axes or the centering bolts are tensioned or relaxed in a simple manner by hand using a Allen key. The hydraulic bracing results in high concentricity. In the embodiment according to claim 1, all front stands, since they are combined into one unit, can be lifted upwards, so that no space need be available for the removal on the front side. It is not necessary to loosen screw connections when changing. The frictional connection of the front and rear stands results in great smoothness. Keyways in the roller axes are not required.

Bei der Ausführungsform nach Anspruch 2 können auch die bedienungsseitigen, also vorderen Ständer ortsfest bleiben. Benötigt wird dabei lediglich ein Magazinständer für jedes Walzgerüst oder ein Magazinständer für sämtliche Walzgerüste. Der Magazinständer nimmt die neu anzubringenden Walzen auf. Er dient auch zur Aufbewahrung derselben. Wenn die Auswechslung der Walzen mittels eines Magazinständers vorgesehen ist, dann muß der Schubweg der hinteren Ständer so groß sein, daß für das Einsetzen des Magazinständers der erforderliche Zwischenraum vorhanden ist.In the embodiment according to claim 2, the operator-side, that is, the front stand can also remain stationary. All you need is a magazine stand for each roll stand or a magazine stand for all roll stands. The magazine stand picks up the newly installed rollers. It also serves to store the same. If the replacement of the rollers by means of a magazine stand is provided, then the pushing distance of the rear stands must be so large that the space required for inserting the magazine stand is available.

Im folgenden werden Ausführungsbeispiele der Erfindung näher beschrieben unter Bezugnahme auf die Zeichnungen.

  • Fig. 1 zeigt eine Ansicht eines Walzengerüstes nach der Erfindung in Betriebsstellung, in Walzrichtung gesehen, zum Teil geschnitten;
  • Fig. 2 zeigt eine entsprechende Ansicht dieses Walzgerüstes in der Einstellung bei dem Dimensionswechsel der Walzen;
  • Fig. 3 ist eine Ansicht eines hinteren (antriebsseitigen Ständers) in Richtung der Walzenachse;
  • Fig. 4 zeigt im Prinzip die Anordnung der vorderen Ständer auf einer gemeinsamen Wechselplatte;
  • Fig. 5 zeigt eine weitere Ausführungsform der Erfindung und zwar eine Ansicht eines Walzgerüstes beim Dimensionswechsel der Walzen.
Exemplary embodiments of the invention are described in more detail below with reference to the drawings.
  • Fig. 1 shows a view of a roll stand according to the invention in the operating position, seen in the rolling direction, partially cut;
  • Fig. 2 shows a corresponding view of this roll stand in the setting when changing the dimensions of the rolls;
  • Fig. 3 is a view of a rear (drive side stator) in the direction of the roll axis;
  • Fig. 4 shows in principle the arrangement of the front stand on a common removable plate;
  • FIG. 5 shows a further embodiment of the invention, namely a view of a roll stand when the rolls change dimensions.

Die Walzenachsen 01 sind nicht in dem hinteren Ständer 02 sondern in dem vorderen Ständer 03 (Bedienungsseite) fest gelagert. Sämtliche vorderen Ständer 03 sind auf einer gemeinsamen Wechselplatte 04 fest montiert.The roller axles 01 are not fixed in the rear stand 02 but in the front stand 03 (operating side). All front stands 03 are permanently mounted on a common removable plate 04.

Bei Dimensionswechsel der Walzen bleiben die hinteren Ständer 02 auf einem Maschinenbett 05.When the rollers change dimensions, the rear stands 02 remain on a machine bed 05.

Die Übertragung des Drehmomentes auf die jeweilige Walze 07 und die Gelenkwelle 06 bzw. Einzelantrieb 08 geschieht über hydraulische Spannelemente 09, die in der Walzenachse 01 integriert sind und gemeinsam beaufschlagt werden.The torque is transmitted to the respective roller 07 and the cardan shaft 06 or individual drive 08 via hydraulic tensioning elements 09, which are integrated in the roller axis 01 and are acted upon together.

Dadurch entfallen die nach dem Stand der Technik erforderlichen Paßfedernuten.This eliminates the feather keys required according to the prior art.

Bei der Erfindung sind die Achsen- bzw. Bohrungstoleranzen so dimensioniert, daß ein Schiebesitz ein leichtes Aufschieben der Walzen 07 gewährleistet. Das Einleiten der Spannkraft geschieht durch Betätigung einer Spannschraube 11 mit Kolben 12, die auf hydraulische Spannelemente 09 einwirken. Durch die hydraulische Spannung ist ein absolut zentrierter Sitz der Walzen gewährleistet. Die Rundlaufgenauigkeit erreicht Spitzenwerte. Außerdem erhalten die Ständer 02 und 03 durch die kraftschlüssige Verbindung der Walzenachsen eine zusätzliche Stabilität, die sich positiv auf die Laufruhe der Anlage auswirkt.In the invention, the axis or bore tolerances are dimensioned such that a sliding seat ensures that the rollers 07 are easily pushed on. The clamping force is introduced by actuating a clamping screw 11 with pistons 12 which act on hydraulic clamping elements 09. The hydraulic tension ensures an absolutely centered fit of the rollers. The concentricity reaches top values. Stands 02 and 03 are also given additional stability due to the frictional connection of the roller axes, which has a positive effect on the smooth running of the system.

Die Wechselplatte 04, auf welcher gemeinschaftlich sämtliche vorderen Ständer 03 angebracht sind, ist auf das Maschinenbett 05 aufgesetzt, durch Bolzen 13 zentriert und wie beschrieben hydraulisch verspannt. Die Betätigung erfolgt durch Spannschrauben 19. Es sind nur zwei Spannbolzen 13 erforderlich.The interchangeable plate 04, on which all the front stands 03 are jointly attached, is placed on the machine bed 05, centered by bolts 13 and hydraulically clamped as described. It is actuated by clamping screws 19. Only two clamping bolts 13 are required.

Bei Dimensionswechsel der Walzen fahren bei jedem Gerüst die oberen Walzenachsen 01 und die zugeordnete untere Walzenachse mittels Spindelgetriebe 16, für die manuelle Betätigung 14 oder ein Servomotor 15 vorgesehen ist, auseinander in eine Endlage, die auf Fig. 2 mit 17 gekennzeichnet ist. Anschließend werden die hydraulischen Systeme in den Walzenachsen über Spannschrauben 11 entspannt. Die kraftschlüssige Verbindung wird dadurch unterbrochen. Die hinteren Ständer 02 fahren mittels einer Schubvorrichtung 18 (Hydraulikzylinder) gemeinschaftlich zur Seite, wie auf Fig. 2 dargestellt, so daß die Walzenachsen 01 aus den Lagerbuchsen 20 der hinteren Ständer 02 herausgelangen. Wie Fig. 2 zeigt, sind dann sämtliche vorderen Ständer 03 frei.When the dimensions of the rollers change, the upper roller axes 01 and the associated lower roller axis move apart in a stand by means of a spindle gear 16, for which manual actuation 14 or a servo motor 15 is provided, into an end position, which is identified by 17 in FIG. 2. The hydraulic systems in the roller axes are then relaxed via tensioning screws 11. The non-positive connection is interrupted. The rear stands 02 travel together to the side by means of a pushing device 18 (hydraulic cylinder), as shown in FIG. 2, so that the roller axles 01 come out of the bearing bushes 20 of the rear stands 02. As shown in FIG. 2, all front stands 03 are then free.

Durch Lösen der Spannschraube 19 an den Bolzen 13 wird die Verbindung der Wechselplatte 04 mit dem Maschinenbett 05 gelöst. Die Wechselplatte kann dann mit sämtlichen vorderseitigen Ständern 03, auf denen sich noch die Walzenachsen und die Walzen befinden, entnommen und durch einen vorbereiteten neuen Ständersatz mit neuen Walzen ersetzt werden. Der Einbau des neuen Ständersatzes, das betriebsfertige Einstellen der gesamten Walzenstraße geschieht in umgekehrter Reihenfolge. Dabei wird die Wechselplatte aufgesetzt und verspannt. Die hinteren Ständer verfahren dann gemeinschaftlich, bis die Walzenachen 01 von den Lagerbuchsen 20 aufgenommen sind. Als dann werden Rollen und Lager hydraulisch verspannt.By loosening the clamping screw 19 on the bolt 13, the connection of the exchangeable plate 04 to the machine bed 05 is released. The removable plate can then with all front stands 03, on which the Roller axes and the rollers are removed and replaced with a prepared new stand set with new rollers. The installation of the new stand set, the ready-to-use setting of the entire roller mill takes place in reverse order. The removable plate is put on and clamped. The rear stands then move together until the roller axles 01 are received by the bearing bushes 20. Then the rollers and bearings are braced hydraulically.

Das auf Fig. 5 dargestellte Walzgerüst hat gleichfalls einen vorderen Ständer 30 und einen hinteren Ständer 32. Beide Ständer sind mit Spindelantrieben 30a ausgerüstet. Fig. 5 zeigt das Walzgerüst in seiner Stellung beim Dimensionswechsel der Walzen. Die beiden Walzenachsen 31 des vorderen Ständers sind frei. Der hintere Ständer 32 ist zur Seite gefahren, so daß sich zwischen den beiden Ständern ein Zwischenraum ergibt, der so groß ist, daß zwischen den freien Walzenachsen 31 und dem hinteren Ständer 32 ein zusätzlicher Zwischenraum ist. In diesem Zwischenraum ist für den Dimensionswechsel ein Magazinständer 40 eingesetzt, der die beiden neu aufzubringenden Walzen 44 trägt.The rolling stand shown in FIG. 5 also has a front stand 30 and a rear stand 32. Both stands are equipped with spindle drives 30a. Fig. 5 shows the roll stand in its position when changing the dimensions of the rolls. The two roller axes 31 of the front stand are free. The rear stand 32 is moved to the side, so that there is a space between the two stands which is so large that there is an additional space between the free roller axles 31 and the rear stand 32. In this space, a magazine stand 40 is used for the change of dimensions, which carries the two new rollers 44 to be applied.

Der Magazinständer 40 hat einen horizontalen Schenkel 42, der auf einer Bahn 45 des Maschinenbettes verschiebbar aufsitzt. An einem vertikalen Schenkel 41 des Magazinständers sind vorstehend zwei Hohldorne 43 gehalten, deren Innenraum die gleichen Abmessungen hat, wie die im hinteren Ständer 32 eingebauten Lagerbuchsen 34. Die neuen Walzen 44 sitzen jeweils verschiebbar auf einem Hohldorn 43. In der dargestellten Stellung sind die Walzenachsen 31, Lagerbuchsen 34 achsgleich eingestellt. Aus der gezeichneten Stellung heraus, wird der Magazinständer 40 mit den neuen Walzen mit Hilfe der Schubvorrichtung 35 in Richtung des Pfeiles nach links gegen den vorderen Ständer 30 geschoben bis in die gestrichelt gezeichnete Stellung 40a, wo die für die Lagerung vorgesehenen Abschnitte 31b der Walzenachsen von den beiden Hohldornen 43 aufgenommen werden. Aus dieser Stellung heraus können die neuen Walzen 44 von Hand die für ihre Lagerung vorgesehenen Abschnitte 31a der Walzenachsen aufgeschoben werden.The magazine stand 40 has a horizontal leg 42 which is slidably seated on a track 45 of the machine bed. On a vertical leg 41 of the magazine stand two hollow mandrels 43 are held above, the interior of which has the same dimensions as the bearing bushes 34 installed in the rear stand 32. The new rollers 44 are each slidably seated on a hollow mandrel 43. In the position shown, the roller axes are 31, bearing bushes 34 set with the same axis. From the position shown, the magazine stand 40 with the new rollers using the Pushing device 35 pushed in the direction of the arrow to the left against the front stand 30 into the position 40a shown in broken lines, where the sections 31b of the roller axes intended for storage are received by the two hollow mandrels 43. From this position, the new rollers 44 can be pushed on the sections 31a of the roller axes intended for their storage by hand.

Nunmehr kann der Magazinständer wieder in den Zwischenraum zurückgeschoben und mittels Kran abgehoben werden. Der hintere Ständer 32 wird gegen den vorderen Ständer verschoben, bis die Achsabschnitte 31b der Walzenachsen von den Lagerbuchsen 34 aufgenommen sind. Alsdann kann die hydraulische Verspannung der Walzen bzw. der Lager wie beschrieben vorgenommen werden.Now the magazine stand can be pushed back into the space and lifted off with a crane. The rear stand 32 is displaced against the front stand until the axle sections 31b of the roller axles are received by the bearing bushes 34. The hydraulic bracing of the rollers or the bearings can then be carried out as described.

Man kann den Magazinständer so bemessen, daß er zwei Walzen für ein Walzgerüst trägt. Man kann aber auch Magazinständer vorsehen, die mehrere Walzenpaare für mehrere Gerüste tragen.The magazine stand can be dimensioned so that it carries two rollers for a roll stand. But you can also provide magazine stands that carry several pairs of rollers for several stands.

Bei der Ausführungsform nach Fig. 5 können auch alternativ die hinteren Ständer 32 feststehend und die vorderen Ständer 30 verschiebbar sein.In the embodiment according to FIG. 5, the rear stands 32 can alternatively also be fixed and the front stands 30 can be displaced.
