Definitions
- the invention relates, according to the preamble of the claim, to an interchangeable, independent supporting device for pivotable, adjustable and fixable guide element supporting bodies of guide elements for rolling stock for the introduction or execution of rolling stock, in particular shaped steel between the rolls of rolling stands, consisting of transverse to the rolling direction , above and below the rolling line, on uprights of the column stands of the rolling stands, which can be moved up and down by lifting motor drives, with which supporting bodies 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.
- Devices of this type serve 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.
- supporting bodies of the guide elements can be moved up and down in a thread-guided manner in a lifting spindles mounted on the outside of the stator spar pairs of the roll stands.
- the pressure spindles are also arranged on the column spindles 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 stator bar 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.
- 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 installed on the rolling stand, ie the rolling operation can only be started when the adjustment of the guide elements has ended .
- Such adjustment work on the roll stand itself is difficult and time-consuming, because other components which are arranged on the roll stand and do not belong to the rolling stock insertion device must also be dismantled and because the use of auxiliary devices for the adjustment by such work within the rolling mill also makes it difficult or difficult is also made impossible.
- 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 adjusting the guide elements and when replacing them.
- 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.

- the support beam can have a bulge protruding between the uprights and completely 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 included the guide elements arranged on the additional supporting beam are kept small in relation to their arrangement in the roll stand.
- pressure-medium-actuated wedge-type clamping bars acting on the ends of the additional supporting beam can be arranged in the push-on direction of the supporting beam.
- the rolling stock in the rolling stand 1, in the windows 1a of which the roller pairs 2 indicated by dash-dotted lines are guided between the inner surfaces of the column stanchions 1b and 1c, the rolling stock, not shown, is inserted between the rollers 2 with the aid of the guide elements 3a and 3b or 4a, 4b forming a pair. and executed from these.
- the pairs of guide elements 3a, 3b and 4a, 4b are articulated with pivot axes 5, 6 lying parallel to the roller to the respective support bodies 7 and 8, which are hook-shaped in cross section, which in turn can be connected to the additional support beams 9 and 10 assigned to them.
- the additional support beams 9, 10 can be connected to the support beams 16 and 17 guided in the roll stand 1 with T-grooves 14 in T-rails 15.
- the supporting sheets 16 and 17 have a protruding toward the rolls 2 of the roll stand 1 between the uprights 1b, 1c, according to the Open bulges 16a and 17a on the side facing away from the rollers 2 and are articulated with their two ends 16b and 17b to the side of the uprights 1b and 1c on these articulated lifting motors 18 and 19.

Abstract
Description
Die Erfindung bezieht sich gemäß Oberbegriff des Patentanspruches auf eine auswechselbare selbständige Tragvorrichtung für schwenk-, einstell- und festlegbare Führungselement-Tragkörper von Führungselementen für Walzgut 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, according to the preamble of the claim, to an interchangeable, independent supporting device for pivotable, adjustable and fixable guide element supporting bodies of guide elements for rolling stock for the introduction or execution of rolling stock, in particular shaped steel between the rolls of rolling stands, consisting of transverse to the rolling direction , above and below the rolling line, on uprights of the column stands of the rolling stands, which can be moved up and down by lifting motor drives, with which supporting bodies 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 Spindelgetriebe 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 serve 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 on the outside of the stator spar pairs of the roll stands. The pressure spindles are also arranged on the column spindles 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 stator bar 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 installed on the rolling stand, ie the rolling operation can only be started when the adjustment of the guide elements has ended . The same applies to the replacement of the guide elements for changes in the rolling program. Apart from the fact that such adjustment work on the roll stand itself is difficult and time-consuming, because other components which are arranged on the roll stand and do not belong to the rolling stock insertion device must also be dismantled and because the use of auxiliary devices for the adjustment by such work within the rolling mill also makes it difficult or difficult 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 adjusting the guide elements and when replacing them.
Diese Aufgabe wird an einer Vorrichtung gemäß Obergriff durch die kennzeichnenden Merkmale des Patentanspruches gelöst.This object is achieved on a device according to the general description by the characterizing features of the claim.
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 rolling 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 einschließlich 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 of the uprights and the additional supporting beam is arranged according to the invention on the side of the supporting beam facing away from the rollers 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 supporting beam and, on the side facing away from the supporting 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 protruding between the uprights and completely 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 included the guide elements arranged on the additional supporting beam are kept small in relation to their arrangement in the roll stand. In both ends of the supporting beam, pressure-medium-actuated wedge-type clamping bars acting on the ends of the additional supporting beam can be arranged in the push-on direction of the supporting beam.
