Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Ein- bzw. Ausführung von Walzgut insb. Formstahl zwischen die Walzen von Walzgerüsten, bestehend aus quer zur Walzrich­tung, oberhalb und unterhalb der Walzlinie liegenden, an Ständerholmpaaren der Walzgerüste hubmotorangetrieben auf- und abbeweglichen Tragbalken, mit denen Tragkörper der je­weiligen Führungselemente eines Führungselementpaares für das Walzgut schwenk-, einstell- und festlegbar verbindbar sind.The invention relates to a device for the introduction and execution of rolling stock, in particular shaped steel between the rolls of roll stands, consisting of support beams which can be moved up and down on the stator pairs of the roll stands, driven transversely to the rolling direction, above and below the rolling line, with which Carrier body of the respective guide elements of a pair of guide elements for the rolling stock can be connected in a pivotable, adjustable and fixable manner.

Vorrichtungen dieser Art dienen dazu, die Position der bei­den Führungselemente unabhängig voneinander zu verändern und einzustellen z.B. die Symmetriemittigkeit des Steges eines zu walzenden Trägers zu verbessern, dessen Steg von den Führungselementen beaufschlagt zwischen die Walzen eines Walzgerüstes ein- bzw. aus diesen ausgeführt wird. Bei einer bekannten Ausbildung (JP-AS 38 762) sind Tragkörper der Führungselemente in einem senkrecht zur Walzebene außen an den Ständerholmpaaren der Walzgerüste gelagerten Hubspindeln gewindegeführt auf- und abbewegbar. Die Druckspindeln werden über ebenfalls an den Ständerholmen angeordnete Spindelge­ triebe von einem gemeinsamen Motor angetrieben. Die Füh­rungselemente sind in ihrem jeweiligen Träger um walzenachs­parallele Schwenkachsen schwenkbar; die Schwenklage der oberhalb der Walzebene angeordneten Führungselemente wird dabei durch einen ebenfalls am Ständerholm angeordneten, zwischen der Schwenkachse und den Walzen mit den Führungs­elementen verbundenen Hubmotor ausgeführt, während die un­terhalb der Walzebene befindlichen Führungselemente mit ihrem Einführungsende auf dem Außenumfang der unteren Walze aufliegen.Devices of this type are used to change and adjust the position of the two guide elements independently of one another, for example to improve the symmetry of the web of a beam to be rolled, the web of which is acted upon by the guide elements between the rollers of a roll stand or is carried out therefrom. In a known design (JP-AS 38 762), supporting bodies of the guide elements can be moved up and down in a thread-guided manner in a lifting spindles mounted perpendicularly to the roll plane on the outside of the stator beam pairs of the roll stands. The pressure spindles are also arranged on the column spars drives driven by a common motor. The guide elements can be pivoted in their respective supports about pivot axes parallel to the rollers; the pivoting position of the guide elements arranged above the roller plane is carried out by a lifting motor which is also arranged on the upright and is connected to the guide elements between the pivot axis and the rollers, while the guide elements located below the roller plane rest with their insertion end on the outer circumference of the lower roller.

Diese Ausbildungsform der gattungsgemäßen Vorrichtung bringt die Nachteile mit sich, daß die Einstellung der Führungsele­mente vor Beginn des Walzbetriebes vorgenommen werden muß, wenn diese bereits an das Walzgerüst montiert worden sind, d.h., der Walzbetrieb kann erst aufgenommen werden, wenn die Einstellung der Führungselemente beendet ist. Das gleiche gilt auch für das Auswechseln der Führungselemente für Än­derungen des Walzprogramms. Abgesehen davon, daß solche Einstellungsarbeiten am Walzgerüst selbst schwierig und zeitraubend sind, weil häufig auch andere am Walzgerüst angeordnete, nicht zu der Walzguteinführungseinrichtung gehörende Bauteile mit abgebaut werden müssen und weil auch die Verwendung von Hilfsvorrichtungen für die Einstellung durch solche Arbeiten innerhalb der Walzenstraße erschwert oder auch unmöglich gemacht wird.This embodiment of the generic device has the disadvantages that the adjustment of the guide elements must be carried out before the start of the rolling operation if they have already been mounted on the rolling stand, ie the rolling operation can only be started when the adjustment of the guide elements has ended . The same also applies to the replacement of the guide elements for changes in the rolling program. Apart from the fact that such adjustment work on the rolling stand itself is difficult and time-consuming, because other components which are arranged on the rolling stand and do not belong to the rolling stock insertion device must also be dismantled, and because the use of auxiliary devices for adjustment by such work within the rolling mill also complicates or is also made impossible.

Der Erfindung liegt die Aufgabe zugrunde, diese Schwierig­keiten und Nachteile zu vermeiden und damit die bei der Einstellung der Führungselemente und bei deren Auswechseln entstehenden Stillstandszeiten der Walzgerüste zu verrin­gern.The object of the invention is to avoid these difficulties and disadvantages and thus to reduce the downtimes of the roll stands that arise when the guide elements are adjusted and when they are replaced.

Diese Aufgabe wird dadurch gelöst, daß die Tragkörper der Führungselemente jeweils auf einem selbständigen Zusatztrag­balken ageordnet sind, der mit dem, mit dem Ständerholmpaar verbundenen Tragbalken auswechselbar lösbar verbind- und festlegbar ist.This object is achieved in that the supporting bodies of the guide elements are each arranged on an independent additional supporting beam, which can be exchangeably detachably connected and fixed to the supporting beam connected to the stator beam pair.

Diese Lösung erlaubt es die Führungselemente außerhalb der Walzenstraße an einem dafür besonders ausgerüsteten Montage­platz am Zusatztragbalken anzubringen und einzustellen, ehe diese zusammen mit dem Zusatztragbalken mit dem Walzgerüst verbunden werden. Dabei kann ein bereits am Gerüst befindli­cher Zusatztragbalken gegen den mit den eingestellten Füh­rungselementen ausgestatteten Zusatztragbalken ausgetauscht werden. Ein solcher Austausch z.B. für einen Wechsel im Walzprogramm erfordert am Walzgerüst verglichen mit dem bei gattungsgemäßen bekannten Vorrichtungen notwendigen Zeitauf­wand und der Montageschwierigkeiten nur wenig Zeit und weni­ge Montagehandgriffe.This solution allows the guide elements to be attached to the additional support beam outside the roller train at a specially equipped assembly location and adjusted before they are connected to the roll stand together with the additional support beam. An additional support beam already on the scaffolding can be exchanged for the additional support beam equipped with the set guide elements. Such an exchange e.g. for a change in the rolling program requires only little time and a few assembly steps on the roll stand compared to the time required for generic devices and the assembly difficulties.

Der den Zusatztragbalken aufnehmende Tragbalken wird zweck­mäßig mit seinen beiden Enden in Führungsnuten der Ständer­holme gleitbar geführt und der Zusatztragbalken erfindungs­gemäß an der den Walzen des Walzgerüstes abgewandten Seite des Tragbalkens angeordnet und mittels in Steckhülsen ein­bringbarer Steckbolzen auf diesen aufgesteckt. Wie die Er­findung weiter vorsieht können die Steckbolzen am Zusatz­tragbalken angeordnet sein und nach der dem Tragbalken abge­wandten Seite eine Kragverlängerung aufweisen, auf die die entsprechenden Aufnahemausnehmungen aufweisenden Tragkörper der Führungselemente aufsteckbar sind. Vorteilhaft kann der Tragbalken dabei in Richtung auf die Walzen des Walzgerüstes hin eine zwischen die Ständerholme ragende, den Zusatztrag­balken ganz oder teilweise mit Abstand einfassende Ausbuch­tung aufweisen, damit die Bautiefe beider Tragbalken ein­ schließlich der am Zusatztragbalken angeordneten Führungs­elemente bezogen auf deren Anordnung im Walzgerüst kleinge­halten wird. In den beiden Enden des Tragbalkens können druckmittelbetätigbare an den Enden den Zusatztragbalkens vorgesehene Auflageflächen in Aufsteckrichtung des Tragbal­kens beaufschlagende Keil-Klemmriegel angeordnet werden.The supporting beam receiving the additional supporting beam is expediently slidably guided with its two ends in guide grooves in the uprights and the additional supporting beam is arranged according to the invention on the side of the supporting beam facing away from the rolls of the roll stand and is plugged onto the latter by means of plug-in pins which can be inserted into plug sleeves. As the invention further provides, the socket pins can be arranged on the additional support beam and, on the side facing away from the support beam, have a cantilever extension onto which the supporting bodies of the guide elements having the corresponding receiving recesses can be attached. Advantageously, the support beam can have a bulge projecting between the stator spars and wholly or partially enclosing the additional support beam in the direction of the rollers of the roll stand, so that the overall depth of both support beams is one finally, the guide elements arranged on the additional support beam are kept small in relation to their arrangement in the roll stand. In the two ends of the support beam, pressure-medium-actuated wedge-type clamping bars acting on the ends of the additional support beam can be arranged in the plug-on direction of the support beam.
