Abstract

The invention concerns a double roller guide for rolling mills, consisting of at least two guide rollers positioned in series in the direction of rolling and mounted on associated roller carriers positioned so that they can pivot and be adjusted according to the position of the guide rollers. In order to make it possible to position the guide rollers in the same direction and in parallel, the roller carriers are two-armed pivoted levers at the one end of which the guide roller is mounted and the other end of which is supported on an adjustable stop, whereby the transmission ratios of both roller carriers are equal and the end of one roller carrier is supported on the other roller carrier at a distance from its pivoting axis.

Description

Die Erfindung betrifft eine Doppelrollenführung für Walzwerke, bestehend aus wenigstens zwei in Walzrichtung hintereinander angeordneten Führungsrollen, die an zugeordneten Rollenträgern gelagert sind, welche schwenkbar und hinsichtlich der Zustellung der Führungsrollen einstellbar angeordnet sind.The invention relates to a double roller guide for rolling mills, consisting of at least two guide rollers arranged one behind the other in the rolling direction, which are mounted on associated roller carriers, which are pivotably arranged and adjustable with respect to the feed of the guide rollers.

Bei verschiedenen Walzverfahren, z.B. bei offenen Straßen und bei kontinuierlichen Straßen mit Schlingenregelung soll die Rollenführung gleichzeitig einen gewissen Richteffekt bewirken. Deswegen werden anstelle eines Rollenpaares zwei Rollenpaare zu einer Doppelrollenführung zusammengeschlossen. Doppelrollenführungen sind in verschiedenen Ausführungsformen bekannt.In various rolling processes, e.g. on open roads and on continuous roads with loop control, the roller guide should also have a certain straightening effect. Therefore, instead of one pair of rollers, two pairs of rollers are combined to form a double roller guide. Double roller guides are known in various embodiments.

Je nach Stahlqualität und Walztemperatur ändern sich die Breitungseffekte des Walzgutes während des Walzprozesses. Speziell für Qualitätsstahl-Walzwerke wird häufig gefordert, daß die Führungen schnell und unkompliziert nachgestellt werden können, um sie den geänderten Verhältnissen des Walzgutes bei Qualitätswechsel anzupassen. Bei einer Doppelrollenführung ist darüber hinaus wichtig, daß die hintereinander geschalteten Rollen auf einer Seite des Walzgutes parallel zueinander verstellt werden. Dazu fehlt es an einer geeigneten Einrichtung.Depending on the steel quality and rolling temperature, the spreading effects of the rolling stock change during the rolling process. Especially for quality steel rolling mills, it is often required that the guides can be adjusted quickly and easily in order to adapt them to the changed conditions of the rolling stock when the quality changes. In the case of a double roller guide, it is also important that the rollers connected in series are adjusted parallel to one another on one side of the rolling stock. There is no suitable facility for this.

Aufgabe der Erfindung ist es, eine Doppelrollenführung der eingangs beschriebenen Gattung so zu verbessern, daß wenigstens zwei in Walzrichtung hintereinander geschaltete Rollen, bei beidseitig des Walzgutes angeordneten Rollenpaaren aber auch alle vier Rollen, zentral und parallel zugestellt werden können.The object of the invention is to improve a double roller guide of the type described at the outset so that at least two rollers connected in series in the rolling direction, but with four pairs of rollers arranged on both sides of the rolling stock, all four rollers can be fed centrally and in parallel.

Diese Aufgabe wird dadurch gelöst, daß die Rollenträger jeweils zweiarmige Schwenkhebel sind, an deren einem Ende die Führungsrolle gelagert ist und deren anderes Ende auf einem verstellbaren Anschlag abgestützt ist, wobei die Übersetzungsverhältnisse beider Rollenträger gleich sind und das Ende eines Rollenträgers auf. dem anderen Rollenträger im Abstand von dessen Schwenkachse abgestützt ist.This object is achieved in that the roller carriers are each two-armed swivel levers, at one end the guide roller is mounted and the other end is supported on an adjustable stop, the transmission ratios of both roller carriers being the same and the end of a roller carrier. the other roller carrier is supported at a distance from its pivot axis.

Bei der erfindungsgemäßen Doppelrollenführung bilden die Rollenträger ein Hebelgetriebe, weil das Ende des einen Rollenträgers gleichzeitig der verstellbare Anschlag für das Ende des anderen Rollenträgers ist. Es genügt folglich, einen der Rollenträger zu verstellen, damit der andere Rollenträger in gleicher Weise verstellt und damit beide Führungsrollen parallel zugestellt werden.In the double roller guide according to the invention, the roller carriers form a lever gear because the end of one roller carrier is at the same time the adjustable stop for the end of the other roller carrier. It is therefore sufficient to adjust one of the roller carriers so that the other roller carrier is adjusted in the same way and thus both guide rollers are delivered in parallel.

Insbesondere sollen die jeweiligen Abstände Drehachse der Führungsrolle-Schwenkachse des Rollenträgers einerseits bzw. Schwenkachse des Rollenträgers-verstellbarer Anschlag andererseits beider Rollenträger gleich sein. Damit wird im Ergebnis eine Art Parallelogrammführung erreicht, wobei jedoch beide Rollenträger nur im Bereich ihrer Schwenkachsen gelagert und im übrigen an den verstellbaren Anschlägen sowie über die Führungsrolle am Walzgut abgestützt sind. Zweckmäßig ist der Abstand der verstellbaren Anschläge (in Walzrichtung) gleich dem Abstand der Schwenkachsen (in Walzrichtung).In particular, the respective distances between the axis of rotation of the guide roller-pivot axis of the roller carrier on the one hand and the pivot axis of the roller carrier-adjustable stop on the other hand should be the same for both roller carriers. The result is a kind of parallelogram guidance, but both roller carriers are only supported in the area of their swivel axes and are supported on the adjustable stops and on the guide roller on the rolling stock. The distance between the adjustable stops (in the rolling direction) is expediently the same as the distance between the swivel axes (in the rolling direction).

Der verstellbare Anschlag für den einen Rollenträger kann eine Kurvenscheibe sein. Durch Verdrehen der Kurvenscheibe wird das darauf abgestützte Ende des Rollenträgers mehr oder weniger verschwenkt und die zugeordnete Führungsrolle des Rollenträgers in Gegenrichtung zugestellt. Das gleiche gilt für den anderen Rollenträger, der der Bewegung des auf der Kurvenscheibe abgestützten Endes zwangsläufig folgt.The adjustable stop for one roller carrier can be a cam. By turning the cam, the end of the roller carrier supported thereon is pivoted more or less and the associated guide roller of the roller carrier is fed in the opposite direction. The same applies to the other roller carrier, which inevitably follows the movement of the end supported on the cam disc.

Die Drehachse der Kurvenscheibe sollte orthogonal zu den Schwenkachsen der Rollenträger angeordnet sein, wobei die Kurvenscheibe wenigstens auf einer Seite eine Stützfläche mit in Umfangsrichtung veränderlichem Abstand zur Mittelebene der Kurvenscheibe aufweist. Wenn die Doppelrollenführung nur auf einer Seite des Walzgutes zwei Führungsrollen aufweist, genügt es, wenn die Kurvenscheibe einseitig eine Stützfläche aufweist.The axis of rotation of the cam should be arranged orthogonally to the swivel axes of the roller carriers, the cam having at least on one side a support surface with a circumferentially variable distance from the central plane of the cam. If the double roller guide has only two guide rollers on one side of the rolling stock, it is sufficient if the cam disc has a support surface on one side.

Die Kurvenscheibe kann aber auch beidseitig Stützflächen aufweisen, die spiegelsymmetrisch zueinander ausgebildet sind, so daß dann auf jeder Stützfläche ein Rollenträger einer Doppelrollenführung mit vier Führungsrollen abgestützt sein kann. Da die Stützflächen spiegelsymmetrisch ausgebildet sind, werden bei einer Verdrehung der Kurvenscheibe alle vier Führungsrollen einer Doppelrollenführung gleichsinnig und parallel zugestellt.The cam can also have support surfaces on both sides, which are mirror-symmetrical to each other, so that a roller carrier of a double roller guide with four guide rollers can then be supported on each support surface. Since the support surfaces are mirror-symmetrical, all four guide rollers of a double roller guide are fed in the same direction and in parallel when the cam disc is rotated.

Eine besonders einfache Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß die Stützflächen eben sind. Die Kurvenscheibe ist dann im Querschnitt keilförmig. Sie läßt sich leicht bearbeiten.A particularly simple embodiment of the invention is characterized in that the support surfaces are flat. The cam disc is then wedge-shaped in cross section. It is easy to edit.

Damit sich die Zustellung der Führungsrollen während des Betriebes nicht verändert, kann eine Feststelleinrichtung für die Kurvenscheibe vorgesehen sein. Das kann beispielsweise eine Klemmschraube sein, mit der die Kurvenscheibe festgelegt wird.So that the infeed of the guide rollers does not change during operation, a locking device can be provided for the cam. This can be, for example, a clamping screw with which the cam disc is fixed.

Im übrigen kann wenigstens eine Feder vorgesehen sein, die die Rollenträger gegen ihre zugeordneten Anschläge drückt.In addition, at least one spring can be provided, which presses the roller carrier against its assigned stops.

Zum Ausgleich von Fertigungstoleranzen und zur Voreinstellung können die abgestützten Enden der Rollenträger Justierschrauben aufweisen, über die sie an den zugeordneten Anschlägen abgestützt sind.To compensate for manufacturing tolerances and for presetting, the supported ends of the roller carriers can have adjusting screws, by means of which they are supported on the assigned stops.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt in schematischer Darstellung teilweise eine Ansicht einer Doppelrollenführung für ein Walzwerk.In the following an embodiment of the invention shown in the drawing is explained; the single figure shows a schematic representation of a partial view of a double roller guide for a rolling mill.

Die dargestellte Doppelrollenführung dient zum Einführen des nicht dargestellten Walzgutes in das Walzenkaliber. Die Doppelrollenführung ist in einem nicht dargestellten Gehäuse oder an einem nicht dargestellten Trägerrahmen angeordnet. Dargestellt ist nur die eine Hälfte der Doppelrollenführung mit zwei Rollenträgern 1,2. Spiegelbildlich zur gezeichneten Mittellinie 3 sind zwei weitere, nicht dargestellte Rollenträger angeordnet.The double roller guide shown serves to introduce the rolling stock, not shown, into the roll caliber. The double roller guide is in a housing, not shown, or on a support frame, not shown arranged. Only one half of the double roller guide with two roller carriers 1, 2 is shown. Two further roller carriers, not shown, are arranged as a mirror image of the center line 3 shown.

Jeder Rollenträger 1 bzw. 2 ist um eine Schwenkachse 4 bzw. 5 schwenkbar im Gehäuse oder am Trägerrahmen gelagert. Am in der Figur linken Ende jedes Rollenträgers 1 bzw. 2 ist eine Führungsrolle 6 bzw. 7 für das Walzgut drehbar gelagert. Am in der Figur rechten Ende jedes Rollenträgers bzw. 2 ist in einer zugeordneten Gewindebohrung eine Justierschraube 8 bzw. g gehalten, die sich orthogonal zu den Schwenkachsen 4 bzw. 5 erstrecken. Die Justierschraube 8 des äußeren Rollenträgers ist auf einem zugeordneten Anschlag 10 des inneren Rollentragers 2 abgestutzt. Die Justierschraube 9 des inneren Rollenträgers 2 ist an einer drehbaren Kurvenscheibe 11 abgestützt, deren Drehachse 12 sich orthogonal zu den Schwenkachsen 4 bzw. 5 erstreckt.Each roller support 1 or 2 is pivotally mounted about a pivot axis 4 or 5 in the housing or on the support frame. At the left end of each roller carrier 1 or 2 in the figure, a guide roller 6 or 7 is rotatably mounted for the rolling stock. At the right end of each roller carrier or 2 in the figure, an adjusting screw 8 or g is held in an associated threaded bore, which extends orthogonally to the pivot axes 4 or 5. The adjusting screw 8 of the outer roller carrier is supported on an associated stop 10 of the inner roller carrier 2. The adjusting screw 9 of the inner roller carrier 2 is supported on a rotatable cam plate 11, the axis of rotation 12 of which extends orthogonally to the pivot axes 4 and 5.

Die Kurvenscheibe 11 besitzt einen keilförmigen Querschnitt, so daß auf beiden Seiten ebene Stützflächen 13, 14 gebildet sind, die in gleichen Koordinaten jeweils gleiche Abstände von der Mittelebene 15 der Kurvenscheibe 11 aufweisen. Auf der Stützfläche 14 ist in entsprechender Weise und spiegelbildlich der Rollenträger des anderen Rollenträgerpaars abgestützt.The cam plate 11 has a wedge-shaped cross section, so that flat support surfaces 13, 14 are formed on both sides, each having the same distances from the central plane 15 of the cam plate 11 in the same coordinates. The roller carrier of the other pair of roller carriers is supported in a corresponding manner and in mirror image on the support surface 14.

Nicht dargestellt ist, daß wenigstens eine Feder vorgesehen ist, die die Rollenträger 1, 2 gegen ihre zugeordneten Anschläge 10 bzw. 13 drückt. Ferner ist nicht dargestellt, daß die Kurvenscheibe 11 an ihrem Außenumfang eine Meßscala sowie im übrigen einen oder mehrere Ansätze für ein Werkzeug zum Drehen der Kurvenscheibe 11 aufweisen kann. Damit die Kurvenscheibe 11 sich während des Betriebes nicht verdreht, ist eine nicht dargestellte Feststelleinrichtung z.B. eine Klemmschraube vorgesehen.It is not shown that at least one spring is provided which presses the roller carriers 1, 2 against their assigned stops 10 and 13, respectively. Furthermore, it is not shown that the cam disk 11 can have a measuring scale on its outer circumference and, moreover, one or more approaches for a tool for rotating the cam disk 11. So that the cam disc 11 does not twist during operation, a locking device, not shown, is e.g. a clamping screw is provided.

Bei der dargestellten Doppelrollenführung sind die Übersetzungsverhältnisse beider Rollenträger 1,2 gleich. Dazu sind die Abstände der jeweiligen Drehachsen der Führungsrollen 6 bzw. 7 von der Schwenkachse 4 bzw. 5 des zugeordneten Rollenträgers 1 bzw. 2 gleich und sind auch die Abstände der Schwenkachsen 4 bzw. 5 der Rollenträger bzw. 2 von den verstellbaren Anschlägen 10 bzw. 11 gleich. Ferner ist der Abstand der Anschläge 10 und 11 gleich dem Abstand der Schwenkachsen 4 und 5.In the double roller guide shown, the gear ratios of both roller carriers 1, 2 are the same. For this purpose, the distances between the respective axes of rotation of the guide rollers 6 and 7 from the pivot axis 4 and 5 of the associated roller carrier 1 and 2 are the same and the distances between the pivot axes 4 and 5 of the roller carriers and 2 from the adjustable stops 10 and 11 equal. Furthermore, the distance between the stops 10 and 11 is equal to the distance between the pivot axes 4 and 5.

Damit wird eine Art Parallelogrammführung verwirklicht, die es ermöglicht, durch Verdrehen der Kurvenscheibe 11 die Führungsrollen 6,7 und die nicht dargestellten Führungsrollen der anderen Seite gleichsinnig und gleichmäßig parallel zu verstellen. Das ist bei den Führungsrollen 6,7 durch strichpunktierte Linien angedeutet.A kind of parallelogram guidance is thus realized, which makes it possible to adjust the guide rollers 6, 7 and the guide rollers (not shown) on the other side in the same direction and uniformly in parallel by rotating the cam disk 11. In the case of the guide rollers 6, 7, this is indicated by dash-dotted lines.

Die Justierschrauben 8,9 dienen zum Ausgleich von Fertigungstoleranzen und auch zur Voreinstellung im Hinblick auf Rarallelität der Führungsrollen 6,7 im Hinblick auf das Walzgut.The adjusting screws 8.9 serve to compensate for manufacturing tolerances and also for presetting with regard to the parallelism of the guide rollers 6, 7 with regard to the rolling stock.
