To provide a simple, operationally reliable and space-saving device, the upper spindle drive (8, 9) has an upper guiding axle (5) on which an eccentric pin (20) connected in articulated fashion to a girder (4) of the narrow side (2) of the mould is rotatably mounted, the rotational position of the pin being determined by the position of the guiding axle (5). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Verstellung von Kokillenschmalseitenwänden zur Breitenverstellung des Gießformates einer Stranggießkokille während des Gießens, wobei eine Kokillenschmalseitenwand durch einen oberen und einen unteren Spindeltrieb verstellbar ist, die gemeinsam durch einen Motor angetrieben und mit der Kokillenschmalseitenwand verbunden sind.The invention relates to a device for adjusting mold narrow side walls for width adjustment of the casting format of a continuous casting mold during casting, wherein a mold narrow side wall is adjustable by an upper and a lower spindle drive, which are driven together by a motor and are connected to the mold narrow side wall.

Bei dieser bekannten Vorrichtung (DE-AS 23 40 768) sind die beiden Spindeltriebe von einem Motor angetrieben, wobei eine Verbindungswelle zum unteren Spindeltrieb mit einer Schaltkupplung versehen ist. Auf diese Weise kann der obere Spindeltrieb zum Schwenken der Kokillenschmalseitenwand allein angetrieben werden. Die Funktionen des Motors und der Schaltkupplung sind geregelt, so daß die Verstellung während des Gießbetriebes in Abhängigkeit von der Formatbreite automatisch ablaufen kann.In this known device (DE-AS 23 40 768), the two spindle drives are driven by a motor, a connecting shaft to the lower spindle drive being provided with a clutch. In this way, the upper spindle drive for pivoting the mold narrow side wall can be driven alone. The functions of the motor and the clutch are regulated so that the adjustment can take place automatically depending on the format width during the casting operation.

Aufgabe der Erfindung ist die Schaffung einer einfachen, betriebssicheren und platzsparenden Vorrichtung zur Breiten- und Konizitätsverstellung der Schmalseitenwände, wobei unkontrollierte Schrägstellungen infolge Rechnerausfall vermieden werden.The object of the invention is to provide a simple, reliable and space-saving device for adjusting the width and conicity of the narrow side walls, uncontrolled inclinations due to computer failure being avoided.

Nach der Erfindung wird dies bei einer Vorrichtung nach dem Oberbegriff des Anspruchs 1 dadurch erreicht, daß der obere Spindeltrieb eine obere Führungsachse aufweist, an der ein mit einem Träger der Kokillenschmalseitenwand gelenkig verbundener Exzenterbolzen drehbar gelagert ist und auf dem Exzenterbolzen Zahnräder befestigt sind, die an je einer an einem Rahmen befestigten Zahnstange im Abrolleingriff sind.According to the invention, this is achieved in a device according to the preamble of claim 1 in that the upper spindle drive has an upper guide axis on which an eccentric bolt articulated to a support of the mold narrow side wall is rotatably mounted and gear wheels are attached to the eccentric bolt a rack attached to a frame is in rolling engagement.

Auf diese Weise wird die Drehstellung des Exzenterbolzens von der Position der Führungsachse bestimmt.In this way, the rotational position of the eccentric pin is determined by the position of the guide axis.

Es wird eine einfache und damit kostengünstige Vorrichtung zum Verstellen von Schmalseitenwänden geschaffen. Die Vorrichtung erfordert nur geringen Einbauraum und ist daher besonders zur Verstellung der Schmalseitenwände von Kokillen für Dünnbrammen geeignet.A simple and therefore inexpensive device for adjusting narrow side walls is created. The device requires only a small installation space and is therefore particularly suitable for adjusting the narrow side walls of molds for thin slabs.

Bei einer Verstellung einer Schmalseitenwand durch die Spindeltriebe wird durch das Abrollen der Zahnräder eine Verdrehung des Exzenterbolzens und damit kontinuierlich eine zusätzliche Verstellung im Umfang der Exzentrizität bewirkt. Ein anderes Verhältnis von Spindelverstellung und Exzenterbolzenverstellung kann durch einen Exzenterbolzen mit anderer Exzentrizität erreicht werden.When adjusting a narrow side wall by means of the spindle drives, the rolling of the gear wheels causes the eccentric bolt to rotate and thus continuously causes an additional adjustment in the scope of the eccentricity. A different ratio of spindle adjustment and eccentric bolt adjustment can be achieved by an eccentric bolt with a different eccentricity.

In weiterer Ausbildung der Erfindung ist der obere Spindeltrieb über ein Kegelradgetriebe mit einer Motorwelle und das Kegelradgetriebe über eine Verbindungswelle mit einem Kegelradgetriebe des unteren Spindeltriebes verbunden, wobei die Verbindungswelle aus zwei durch eine Verstellkupplung verbundenen Abschnitten besteht.In a further embodiment of the invention, the upper spindle drive is connected to a motor shaft via a bevel gear mechanism and the bevel gear mechanism is connected to a bevel gear mechanism of the lower spindle drive mechanism via a connecting shaft, the connecting shaft consisting of two sections connected by an adjusting coupling.

Bei einer aus zwei Breitseitenwänden 1 und zwei Schmalseitenwänden 2 bestehenden Kokille zum Gießen von Dünnbrammen ist mindestens eine Schmalseitenwand 2 zur Formateinstellung zwischen den Breitseitenwänden 1 verstellbar. Hierzu ist die an einem Halter 3 befestigte Schmalseitenwand 2 über einen Träger 4 mit einer oberen und einer unteren Führungsachse 5, 6 verbunden. Die in einem Rahmen 7 aufgenommenen Führungsachsen 5, 6 sind zu ihrer Längsverschiebung innen mit einer Mutter 8 versehen, in die je eine Gewindespindel 9 eingeschraubt sind.In the case of a mold for casting thin slabs consisting of two broad side walls 1 and two narrow side walls 2, at least one narrow side wall 2 can be adjusted between the wide side walls 1 for setting the format. For this purpose, the narrow side wall 2 fastened to a holder 3 is connected via a carrier 4 to an upper and a lower guide axis 5, 6. The guide axes 5, 6 accommodated in a frame 7 are provided with a nut 8 on the inside for their longitudinal displacement, into each of which a threaded spindle 9 is screwed.

Die Gewindespindeln 9 sind mit je einem oberen und einem unteren Kegelradgetriebe 11, 12 verbunden, die durch eine mit einer Verstellkupplung 13 versehene Welle 14 verbunden sind. Eine Antriebswelle 15 treibt das obere Kegelradgetriebe 11 an. Durch die Verstellkupplung 13 kann die gegenseitige Drehlage der Kegelradgetriebe 11, 12 verändert werden.The threaded spindles 9 are each connected to an upper and a lower bevel gear 11, 12, which are connected by a shaft 14 provided with an adjusting coupling 13. A drive shaft 15 drives the upper bevel gear 11. The mutual rotational position of the bevel gear 11, 12 can be changed by the adjusting clutch 13.

Die untere Führungsachse 6 ist mit einer Gabel 16 versehen, die den Träger 4 umgreift. Gabel 16 und Träger 4 sind gelenkig durch einen mit Vertikalspiel gelagerten Bolzen 17 verbunden.The lower guide axis 6 is provided with a fork 16 which engages around the carrier 4. Fork 16 and carrier 4 are articulated by a bolt 17 mounted with vertical play.

Zur Erzielung einer Schwenkbewegung um den Bolzen 17 bei einer Verstellung der Schmalseitenwand 2 ist der Träger 4 im oberen Teil mit einem Lager 18 auf einem Exzenter 19 eines Exzenterbolzens 20 aufgenommen, der in einer mit der oberen Führungsachse 5 verbundenen Gabel 21 gelagert ist. Auf beiden Enden des Exzenterbolzens 20 sind Zahnräder 22 befestigt. Die Zahnräder 22 sind an am Rahmen 7 befestigten Zahnstangen 23 im Abrolleingriff.In order to achieve a pivoting movement about the bolt 17 when the narrow side wall 2 is adjusted, the carrier 4 is accommodated in the upper part with a bearing 18 on an eccentric 19 of an eccentric bolt 20 which is mounted in a fork 21 connected to the upper guide axis 5. Gears 22 are attached to both ends of the eccentric bolt 20. The gear wheels 22 are in rolling engagement on racks 23 fastened to the frame 7.

Bei einer Verschiebung der oberen Führungsachse 5 wird der Exzenterbolzen 20 durch das Abrollen der Zahnräder 22 an den Zahnstangen 23 gedreht, wodurch die Distanz zwischen Führungsachse 5 und dem Halter 3 zur Konizitätsveränderung kontinuierlich vergrößert oder verkleinert wird. Durch das geringe Vertikalspiel des Bolzens 17 in der Gabel 16 der unteren Führungsachse 6 wird eine Verklemmung der Führungsachsen 5 und 6 vermieden.When the upper guide axis 5 is displaced, the eccentric bolt 20 is rotated by the rolling of the gear wheels 22 on the toothed racks 23, as a result of which the distance between the guide axis 5 and the holder 3 for changing the taper is continuously increased or decreased. Due to the low vertical play of the bolt 17 in the fork 16 of the lower guide axis 6 jamming of the guide axes 5 and 6 is avoided.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt.The invention is not restricted to the exemplary embodiment shown.
