Abstract

1. A roll stand, for example a universal roll stand having horizontal and vertical roll sets arranged in a common vertical axial plane, the roll stand either being movable along displacement paths on rollers directly into and out of the roll axis for changing the stand and being securable in the roll axis to the base plates on being lifted from the displacement paths, or being movable by means of shortstroke displacement means indirectly into and out of the roll axis from the displacement paths terminating at the sides of the roll axis and being securable in the roll axis to the base plates of the roll stand, characterised in that the roll stand has its own drive (14), which is in driving connection with the rollers (10) and forms the displacement drive along the displacement paths (12a and 13a) by using the dead weight of the roll stand.

Description

Die Erfindung betrifft ein Walzgerüst, beispielsweise ein Universalwalzgerüst mit in einer gemeinsamen vertikalen Achsebene angeordneten Horizontal- und Vertikalwalzensätzen, welches zum Gerüstwechsel entweder längs Führungsbahnen auf Rollen direkt in die Walzlinie bzw. aus dieser bewegbar und in der Walzlinie unter Abheben von den Führungsbahnen mit den Sohlplatten verspannbar oder indirekt mittels kurzhubiger Verschiebemittel von den seitlich der Walzlinie endenden Führungsbahnen in bzw. aus der Walzlinie verschiebbar und auf den Sohlplatten des Walzgerüstes in der Walzlinie arretierbar ist.The invention relates to a roll stand, for example a universal roll stand with horizontal and vertical roll sets arranged in a common vertical axis plane, which can be moved either along guide tracks on rollers directly into or out of the rolling line and in the rolling line while lifting off the guide tracks with the base plates can be braced or moved indirectly by means of short-stroke displacement means from the guide tracks ending at the side of the rolling line into and out of the rolling line and can be locked in the rolling line on the base plates of the rolling stand.

Es ist bereits bekannt, Walzgerüste zum Ein- und Ausfahren aus der Walzlinie mittels Hubzylindern, Ketten mit Kettenantrieben, Seilen mit Seilwinden oder mit Ausziehwagen mit Antrieb (Ritzel und Zahnstangen) bei relativ kurzen Verfahrwegen zu verschieben.It is already known to move roll stands for moving in and out of the rolling line by means of lifting cylinders, chains with chain drives, ropes with cable winches or with pull-out carriages with drive (pinion and racks) with relatively short travel distances.

Diese Verfahr- bzw. Verschiebeantriebe sind infolge ihres baulichen und räumlichen Aufwandes jedoch nur für leichtere Walzgerüste mit relativ kurzen Verfahrwegen geeignet. Bei schweren Walzgerüsten sind derartige Einrichtungen besonders im Hinblick auf einen schnellen Gerüstwechsel bei langen Verfahrwegen zu den Zurichtereien infolge des erforderlichen baulichen Aufwandes nicht geeignet.However, due to their constructional and spatial complexity, these traversing and shifting drives are only suitable for lighter rolling stands with relatively short travels. Such devices are special in the case of heavy rolling stands not suitable in view of a quick change of scaffolding with long travels to the dressing shops due to the structural effort required.

Aufgabe der Erfindung ist es, auch schwere Walzgerüste sehr schnell und mit geringstem baulichen Aufwand über lange Verfahrwege beim Gerüstwechsel bewegen zu können.The object of the invention is to be able to move even heavy roll stands very quickly and with the least structural effort over long travels when changing stands.

Zur Lösung der gestellten Aufgabe wird vorgeschlagen, daß das Walzgerüst einen ortsfesten Antrieb aufweist, der getrieblich mit den Rollen verbunden und unter Ausnutzung des Eigengewichtes des Walzgerüstes den Verfahrantrieb längs der Führungsbahnen bildet.To solve the problem, it is proposed that the roll stand has a stationary drive which is connected to the rollers in a geared manner and forms the traversing drive along the guideways using the weight of the roll stand.

Vorteil einer solchen Anordnung ist, daß das Eigengewicht des Walzgerüstes zur besonders guten Übertragung des Drehmomentes von den Rollen auf die Führungsbahnen und die dadurch bedingten guten Auflagekräfte genutzt wird. Es kann somit ein beliebig langer Verfahrweg des Walzgerüstes schnell durchfahren werden, wobei jegliche, räumlich hindernden und baulich aufwendigen Hilfseinrichtungen in vorteilhafter und kostensparender Weise entfallen können. Die Vorrichtung ist einfach und vermeidet eine zusätzliche Behinderung des Bedienungspersonals beim Querverfahren des Walzgerüstes.The advantage of such an arrangement is that the dead weight of the roll stand is used for the particularly good transmission of the torque from the rollers to the guideways and the resulting good contact forces. An arbitrarily long travel path of the roll stand can thus be traveled quickly, any auxiliary devices which are spatially obstructing and structurally complex can be dispensed with in an advantageous and cost-saving manner. The device is simple and avoids an additional hindrance to the operating personnel when the rolling stand is moved crosswise.

Ein Ausführungsbeispiel der Erfindung stellt die Zeichnung dar. Es zeigt:

  • Fig. 1 ein Universalwalzgerüst in der Seitenansicht mit Verfahrantrieb und
  • Fig. 2 das Universalgerüst in der Vorderansicht.
The drawing represents an embodiment of the invention. It shows:
  • Fig. 1 shows a universal roll stand in side view with traversing drive and
  • Fig. 2 shows the universal scaffold in the front view.

In der Fig. 1 und 2 ist ein Universalwalzgerüst 1 mit in einer gemeinsamen vertikalen Achsebene angeordneten Horizontalwalzen 2, 3 und Vertikalwalzen 4, 5 im Prinzip dargestellt. Die Anstellung der Horizontalwalzen 2, 3 erfolgt durch einen Verstellantrieb 7, während die Anstellung der Vertikalwalzen 4, 5 jeweils seitlich von Anstellantrieben 8 und 9 vorgenommen wird.1 and 2, a universal roll stand 1 with horizontal rolls 2, 3 and vertical rolls 4, 5 arranged in a common vertical axis plane is shown in principle. The horizontal rollers 2, 3 are adjusted by an adjusting drive 7, while the vertical rollers 4, 5 are adjusted laterally by adjusting drives 8 and 9.

Das Walzgerüst stützt sich über auf Achsen 11 gel ,erten Rollen 10 auf einer Führungsbahn 12 ab, die sich im Bereich der Walzlinie als Sohlplatte 13 fortsetzt. An dem Walzgerüst 1 ist im Bereich der Achse 11 ein Antriebsmotor 14 angeordnet, welcher über ein Zwischengetriebe 15 auf die Achse 11 und damit auf die Rollen 10 mit dem Eigengewicht des Walzgerüstes 1 kraftübertragend wirksam ist und damit den Verfahrantrieb des Walzgerüstes zum Ausfahren oder Einfahren in die Walzlinie beim Gerüstwechsel bildet. Der Antriebsmotor 14 ist über mitlaufende Kabelrollen mit der elektrischen Stromversorgung verbunden.The roll stand is supported by gel on axes 11, rollers 10 on a guide track 12, which continues in the area of the rolling line as a base plate 13. On the roll stand 1, a drive motor 14 is arranged in the area of the axis 11, which is force-transmitting via an intermediate gear 15 on the axis 11 and thus on the rollers 10 with the weight of the roll stand 1 and thus the travel drive of the roll stand for extending or retracting in forms the rolling line when changing stands. The drive motor 14 is connected to the electrical power supply via idler cable reels.

In dem Ausführungsbeispiel der Fig. 1 und 2 wird das Walzgerüst auf den Führungsbahnen 12 bis seitlich neben die Walzlinie gefahren und dann mittels eines Hubzylinders 15 auf eine keilförmig ausgebildete Gegenfläche 16 der unteren, entsprechend ausgebildeten Gerüstauflagefläche in die Walzlinie gezogen, wobei sich die Rollen 10 von der Führungsbahn 12 abheben. So dann wird das Walzgerüst mittels der Klemmzylinder 17 mit der Sohlplatte 13 verspannt, indem sich die Klemmkolben 17a in Ausnehmungen 1a der Klemmleisten des GerüstfuBes des Walzgerüstes 1 einlegen.In the exemplary embodiment in FIGS. 1 and 2, the rolling stand is moved on the guideways 12 to the side next to the rolling line and then pulled into the rolling line by means of a lifting cylinder 15 onto a wedge-shaped counter surface 16 of the lower, correspondingly designed stand bearing surface, the rollers 10 Lift off the guideway 12. So then the roll stand is clamped to the base plate 13 by means of the clamping cylinders 17 by the clamping pistons 17a inserting themselves into recesses 1a in the clamping strips of the stand foot of the roll stand 1.

Es ist auch möglich, das Walzgerüst 1 mittels des Verfahrantriebes 14 bis in die Walzlinie zu bewegen, wo dann das Walzgerüst mittels eines hydraulisch oder dergleichen betätigbaren Hubtisches angehoben und damit mit den Rollen 10 von der Führungsbahn 12 abgehoben und in vorbeschriebener Weise mit den Sohlplatten über die Klemmzylinder 17 verspannt wird.It is also possible to move the roll stand 1 by means of the traversing drive 14 into the rolling line, where the roll stand is then lifted by means of a hydraulically or similarly operated lifting table and thus lifted from the guide track 12 by the rollers 10 and in the manner described above with the base plates the clamping cylinder 17 is clamped.

Da bei schweren Walzgerüsten wie Universal-, Duo- oder Triowalzgerüsten sehr häufig lange Verfahrwege zu überwinden sind, ist der Direktantrieb des Walzgerüstes als Verfahrantrieb besonders vorteilhaft, da damit kostenaufwendige Hilfseinrichtungen eingespart werden und die Wechselzeiten für die schweren Walzgerüste weiter verkürzt werden.Since long travel distances are very often to be overcome with heavy roll stands such as universal, duo or trio roll stands, the direct drive of the roll stand as a travel drive is particularly advantageous, since it saves costly auxiliary equipment and further shortens the changing times for the heavy roll stands.

Das Ausführungßbeispiel stellt ein Universalgerüst dar, doch ist der Verfahrantrieb ebenso bei schweren Duo-, Trio-, Quarto- und Mehrrollenwalzgerüsten sowie bei Gerüstbauarten wie Vertikal- bzw. Kippgerüsten anwendbar.The exemplary embodiment represents a universal stand, but the traversing drive can also be used for heavy duo, trio, four-high and multi-roll mill stands as well as for stand types such as vertical or tilting stands.
