Abstract

Directional drives are for example used upstream of coilers in mill stands for coiling up the strip in a defined manner. A first roll (5) that can be placed against a second roll (6) is used to adjust or control the desired strip tension and a lateral deviation of the strip. The directional drive (1) according to the invention has an especially simple design and can be controlled in a very precise manner. For this purpose, the rockers (2, 3) on which the roll (5) which can be placed against the second roll is mounted are separately mounted in a frame (12) so as to be swiveled and can therefore be swiveled independently.

Description

Die gegenständliche Erfindung betrifft einen Lenktreiber mit zwei Walzen, wobei eine erste Walze im Wesentlichen stationär und eine zweite Walze gegen die erste Walze anstellbar angeordnet ist, und mit zwei verschwenkbaren Schwingen, in denen die zweite Walze gelagert angeordnet ist, und an denen zum Verschwenken der Schwingen jeweils ein Druckmittelzylinder angeordnet ist.The subject invention relates to a steering wheel driver with two rollers, wherein a first roller is arranged substantially stationary and a second roller against the first roller engageable, and with two pivotable rockers, in which the second roller is mounted, and in which for pivoting the Swinging a pressure medium cylinder is arranged in each case.

Lenktreiber kommen typischerweise in Walzstraßen zum Einsatz, wo sie vor Walzbandhaspeln angeordnet werden, um den Bandzug vor der Haspel mittels zwei Walzen einzustellen. Eine andere Aufgabe des Lenktreibers besteht darin, seitliche Wanderungen des Walzbandes vor dem Aufhaspeln zu verhindern. Dazu wird eine verschwenkbare Walze so angesteuert und gegen eine stationäre Walze angestellt, dass durch die Lage dieser Walze gegenüber der stationären Walze das Walzband einen gewünschten Bandzug und eine gewünschte seitliche Verschiebung erfährt.
Ein solcher Lenktreiber geht z.B. aus der EP 192 982 B1 oder der DE 26 15 254 A1 hervor, die einen Treiber zeigen, deren verschwenkbare Walze in einer durchgehenden Schwinge gelagert ist. Die Lagerung dieser Walze ist durch Steuerzylinder beweglich, sodass die Walze über ihre Lagerung entsprechend bewegt werden kann. Ein solcher Treiber weist jedoch aufgrund der beweglichen Lagerung einen sehr aufwendigen Aufbau auf.
Die EP 747 147 B1 zeigt einen Lenktreiber, dessen verschwenkbare Walze in zwei Schwingen gelagert ist, an denen jeweils ein Druckmittelzylinder angreift und die Schwingen dadurch separat angesteuert werden können. Die beiden Schwingen sind starr mit einer Torsionsfeder verbunden, die die Drehachse der Schwingen bildet. Bei der Ansteuerung der Schwingen über die Druckmittelzylinder beeinflussen sich diese gegenseitig und es ist die Federkonstante der Torsionsfeder in der Kraftregelung immer zu berücksichtigen. Die Federkonstante ist jedoch nicht exakt bekannt und ändert sich zudem noch mit den äußeren Bedingungen, z.B. mit der Umgebungstemperatur, Materialeigenschaften der Feder, etc., sodass die Regelung eine gewisse innewohnende Ungenauigkeit aufweist.Steering drivers are typically used in rolling mills where they are placed in front of rolled strip reels to set the strip tension in front of the reel by means of two rolls. Another object of the steering operator is to prevent lateral migrations of the rolled strip before being coiled. For this purpose, a pivotable roller is so driven and employed against a stationary roller, that by the position of this roller relative to the stationary roller, the rolled strip undergoes a desired strip tension and a desired lateral displacement.
Such a steering driver goes for example from the EP 192 982 B1 or the DE 26 15 254 A1 showing a driver whose pivotal roller is mounted in a continuous rocker. The storage of this roller is movable by control cylinder, so that the roller can be moved according to their storage. However, such a driver has due to the movable storage on a very complex structure.
The EP 747 147 B1 shows a steering driver whose pivotal roller is mounted in two rockers, where each a pressure medium cylinder attacks and the wings can be controlled separately. The two wings are rigidly connected to a torsion spring, which forms the axis of rotation of the rockers. In the control of the rockers on the pressure cylinder, these influence each other and it is the spring constant of the torsion spring in the force control always considered. However, the spring constant is not exactly known and also changes with the external conditions, such as the ambient temperature, material properties of the spring, etc., so that the scheme has a certain inherent inaccuracy.

Aus der EP 1 086 916 A2 ist eine Lagereinheit für eine anstellbare Zugwalze zu entnehmen, die aus zwei auf einer Achse starr fixierten Einheiten bestehen, wobei jeweils um weitere Achsen eine gemeinsame Welle durch schwenken angestellt wird. Nachteilig ist der komplexe Aufbau und die geringe Stabilität bei hohen Lasten.From the EP 1 086 916 A2 is to remove a bearing unit for a engageable draw roller, consisting of two rigidly fixed on one axis units, in each case about a further axis a common shaft is made by pivoting. A disadvantage is the complex structure and low stability at high loads.

Es ist nun eine Aufgabe der gegenständlichen Erfindung, einen Lenktreiber anzugeben, der den bekannten Stand der Technik verbessert, indem er einfach aufgebaut und einfach und genau steuerbar ist.It is now an object of the subject invention to provide a steering actuator which improves on the known state of the art by being simple in construction and simple and precisely controllable.

Diese Aufgabe wird durch einen Lenktreiber gelöst, der die Merkmale des Anspruchs 1 aufweist.
Durch die separaten Schwingen, kann der Lenktreiber sehr einfach aufgebaut werden und es müssen keine gegenseitigen Beeinflussungen von miteinander verbundenen Schwingen berücksichtigt werden, was den Lenktreiber sehr einfach und vor allem auch genau steuerbar macht.This object is achieved by a steering driver having the features of claim 1.
Due to the separate wings, the steering actuator can be very easily built and it It is not necessary to take into account mutual influences of interconnected rockers, which makes the steering driver very simple and, above all, precisely controllable.

Besonders vorteilhaft werden die Schwingen an einem ihrer Enden am Rahmen gelagert und wird jeweils am anderen Ende der Druckmittelzylinder angeordnet und zwischen den beiden Enden an den Schwingen die Lagerung der zweite Walze angeordnet, da sich dabei unter Anderem günstige Hebelverhältnisse ergeben.Particularly advantageously, the rockers are mounted at one of their ends on the frame and is arranged in each case at the other end of the pressure cylinder and arranged between the two ends of the rockers, the bearing of the second roller, as there are, inter alia, favorable leverage.

Eine besonders bevorzugte Ausgestaltung erhält man, indem man am Rahmen eine Achse drehbar gelagert anordnet und eine der beiden Schwingen starr mit dieser Achse verbindet, was noch weiter verbessert werden kann, indem die zweite Schwinge verschwenkbar mit der Achse verbunden wird. Der konstruktive Aufbau wird dadurch vereinfacht, da nur eine einzige Achse erforderlich ist, um beide Schwingen unabhängig voneinander drehbar zu lagern.A particularly preferred embodiment is obtained by arranging an axle rotatably mounted on the frame and one of the two wings rigidly connected to this axis, which can be further improved by the second rocker is pivotally connected to the axle. The structural design is simplified because only a single axis is required to support both wings rotatably independently.

Die Funktionssicherheit des Lenktreibers wird erhöht, wenn eine Verschwenksicherung vorgesehen wird, um zu verhindern, dass sich eine Schwinge zu weit verschwenkt wird und dadurch Teile des Lenktreibers oder der Schwinge, z.B. eine Lagerung oder eine Dichtung, beschädigt oder zerstört werden könnten.The reliability of the steering actuator is increased when a Verschwenksicherung is provided to prevent a rocker is pivoted too far and thereby parts of the steering drive or the rocker, e.g. a bearing or seal could be damaged or destroyed.

Besonders vorteilhaft ist die Lagerung der Walze und die Lagerung der Schwinge in einer Linie angeordnet, sodass durch die Betätigungskraft der Betätigungseinrichtung kein Kippmoment entsteht.Particularly advantageously, the bearing of the roller and the bearing of the rocker is arranged in a line, so that no tilting moment is created by the actuating force of the actuator.

Der erfindungsgemäße Lenktreiber wird nachfolgend anhand der beispielhaften, nicht einschränkenden Figur 1 beschrieben, die einen solchen Lenktreiber in dreidimensionaler Ansicht zeigt.The steering driver according to the invention is described below with reference to the exemplary, non-limiting FIG. 1 described, which shows such a steering driver in three-dimensional view.

Der Lenktreiber 1 in Fig. 1 besteht im Wesentlichen aus einem Rahmen 12, in dem eine erste Walze 6 in einer Lagerung 8 hier im Wesentlichen stationär gelagert ist. Stationär gelagert bedeutet hier, dass sich die Walze zwar drehen kann, diese aber bezüglich des Rahmens 12 im Wesentlichen keine weiteren Freiheitsgrade besitzt. Eine zweite Walze 5 ist in einer weiteren Lagerung 7 drehbar gelagert und ist gegenüber der ersten Walze 6 anstellbar angeordnet, kann also relativ zur ersten Walze 6 bewegt werden. Dazu sind zwei Schwingen 2, 3 vorgesehen, die um eine Drehachse 13 verschwenkbar am Rahmen angeordnet sind. An den Schwingen 2, 3 ist die zweite Walze 5 in der Lagerung 7 drehbar angeordnet und am freien Ende der Schwingen 2, 3 ist jeweils eine Betätigungseinrichtung 4, wie z.B. hier ein Druckmittelzylinder, vorzugsweise ein Hydraulikzylinder, angeordnet.The steering driver 1 in Fig. 1 consists essentially of a frame 12, in which a first roller 6 is mounted here in a storage 8 substantially stationary. Stored here means that although the roller can rotate, it has essentially no further degrees of freedom with respect to the frame 12. A second roller 5 is rotatably mounted in a further bearing 7 and is arranged adjustable relative to the first roller 6, so it can be moved relative to the first roller 6. For this purpose, two rockers 2, 3 are provided, which are arranged pivotably about an axis of rotation 13 on the frame. On the wings 2, 3, the second roller 5 is rotatably mounted in the bearing 7 and at the free end of the rockers 2, 3 is in each case an actuating device 4, such as here a pressure medium cylinder, preferably a hydraulic cylinder arranged.

Die Schwingen 2, 3 sind separat und unabhängig voneinander bewegbar am Rahmen 12 gelagert. Im Beispiel nach Fig. 1 ist dazu eine Achse 9, in Form eines Rohrs, in zwei Lagern 10, hier z.B. Wälzlager, wie z.B. ein Rollenlager oder Pendelrollenlager, drehbar am Rahmen 12 gelagert. Mit der Achse 9 ist eine Schwinge 3 fest verbunden, z.B. durch eine Schweißung wie in Fig. 1 angedeutet. Die zweite Schwinge 2 ist mittels einem Lager 11, hier wieder ein Wälzlager, drehbar an der Achse 9 angeordnet. Die beiden Schwingen 2, 3 können daher vollkommen unabhängig voneinander bewegt werden.The rockers 2, 3 are mounted separately and independently movable on the frame 12. In the example below Fig. 1 For this purpose, an axle 9, in the form of a tube, in two bearings 10, here for example rolling bearings, such as a roller bearing or spherical roller bearings, rotatably mounted on the frame 12. With the axis 9 a rocker 3 is firmly connected, for example by a weld as in Fig. 1 indicated. The second rocker 2 is rotatably arranged on the axis 9 by means of a bearing 11, here again a rolling bearing. The two wings 2, 3 can therefore be moved completely independently of each other.

Es wäre jedoch natürlich genauso denkbar, die beiden Schwingen 2, 3 jeweils in geeigneter Weise verschwenkbar auf einer eigenen mit dem Rahmen verbundenen Achse oder eigenem Zapfen, wobei die Schwinge 2, 3 fest mit der Achse oder dem Zapfen verbunden oder auf diesen gelagert sein könnte, oder direkt am Rahmen 12 zu lagern. Ebenso könnte am Rahmen 12 eine Achse starr angeordnet werden, auf der die Schwingen 2, 3 verschwenkbar gelagert sein könnten.However, it would of course also just conceivable, the two wings 2, 3 each in a suitable manner pivoted on its own connected to the frame axis or its own pin, the rocker 2, 3 could be fixed to the axle or the pin or stored on this , or directly to the frame 12 to store. Likewise, an axis could be rigidly arranged on the frame 12, on which the rockers 2, 3 could be mounted pivotably.

Der Druckmittelzylinder 4 ist hier mit einem Ende an der Schwingen 2, 3 und mit seinem anderen Ende jeweils am Rahmen 12 befestigt, sodass durch Beaufschlagen des Druckmittelzylinders 4 die zweite Walze 5 um die Drehachse 13 verschwenkt und relativ zur ersten Walze 6 bewegt werden kann. Der Angriffspunkt des Druckmittelzylinders 4, die Lagerung 7 der Walze 5 in der Schwinge 2, 3 und die Lagerung 11 der Schwinge 2 auf der Achse 9 bzw. die starre Verbindung zwischen Schwinge 3 und Achse 9 ist dabei bevorzugt jeweils in einer Linie angeordnet, sodass in den Schwingen 2, 3 durch die vom Druckmittelzylinder 4 ausgeübten Kräfte keine Kippmomente verursacht werden. Der Druckmittelzylinder 4 könnte aber auch an einem seitlich herausragenden Vorsprung der Schwingen 2, 3 befestigt sein.The pressure cylinder 4 is fixed here with one end to the wings 2, 3 and with its other end respectively to the frame 12, so that by applying the pressure cylinder 4, the second roller 5 can be pivoted about the rotation axis 13 and moved relative to the first roller 6. The point of application of the pressure cylinder 4, the bearing 7 of the roller 5 in the rocker 2, 3 and the bearing 11 of the rocker 2 on the axis 9 and the rigid connection between rocker 3 and axis 9 is preferably arranged in each case in a line, so no tilting moments are caused in the wings 2, 3 by the forces exerted by the pressure medium cylinder 4 forces. However, the pressure cylinder 4 could also be attached to a laterally projecting projection of the wings 2, 3.

Das Federpaket 14, das jeweils zwischen den Schwingen 2, 3 und der Lagerung 16 des Federpakets 14 angeordnet ist, dient im Wesentlichen dazu, das Lager 7 der Walze 5 nach oben zu ziehen, um so das Lagerspiel zu eliminieren bzw. zumindest zu verkleinern. Damit sollen Schläge auf das Lager 7 der zweiten Walze 5 beim Einfahren des Bandes zwischen die Walzen 5, 6 vermieden werden.The spring assembly 14, which is arranged in each case between the rockers 2, 3 and the bearing 16 of the spring assembly 14, essentially serves to pull the bearing 7 of the roller 5 upwards so as to eliminate or at least reduce the bearing clearance. This should be avoided impacts on the bearing 7 of the second roller 5 when retracting the belt between the rollers 5, 6.

Weiters kann wie in Fig. 1 angedeutet eine Verschwenksicherung 15 vorgesehen sein, um die Schwenkbewegung der auf der Achse 9 verschwenkbar angeordneten Schwinge 2 zu begrenzen. Damit wird verhindert, dass im Falle einer Fehlfunktion ein zulässiger Schwenkwinkel z.B. des Lagers oder einer Dichtung nicht überschritten werden kann. Die Verschwenksicherung 15 kann dabei so ausgeführt werden, dass auf der Achse 9 zwei Anschläge vorgesehen sind, die die Grenzen der Schwenkbewegung vorgeben, zwischen denen sich ein weiterer, mit der Schwinge 2 verbundener und mitbewegender Anschlag bewegt.Furthermore, as in Fig. 1 indicated a Verschwenksicherung 15 may be provided to limit the pivotal movement of the pivotable about the axis 9 rocker 2. This prevents that in case of malfunction a permissible swivel angle, for example, of the bearing or a seal can not be exceeded. The Verschwenksicherung 15 can be carried out so that on the axis 9 two stops are provided which specify the limits of the pivoting movement, between which another, connected to the rocker 2 and moving mitbewegender stop moves.

Die Funktion des Lenktreibers 1 ist aus dem Stand der Technik bereits hinlänglich bekannt und muss daher nicht mehr im Detail beschrieben werden. Zwischen den beiden Walzen 5, 6 wird ein Walzband durchgeführt, dessen Bandzug und seitliche Bewegung mittels des Lenktreibers 1 eingestellt werden kann, in dem die Schwingen 2, 3 durch die Druckmittelzylinder 4 verschwenkt werden und so die zweite Walze 5 in gewünschter Weise gegen die erste Walze 6 angestellt wird. Die Druckmittelzylinder 4 sind dabei entsprechend anzusteuern und eine entsprechende Regelung ist gegebenenfalls vorzusehen.The function of the steering actuator 1 is already well known from the prior art and therefore need not be described in detail. Between the two rollers 5, 6, a rolled strip is performed, the strip tension and lateral movement can be adjusted by means of the steering driver 1, in which the rockers 2, 3 are pivoted by the pressure cylinder 4 and thus the second roller 5 in a desired manner against the first Roller 6 is turned on. The pressure cylinder 4 are to be controlled accordingly and a corresponding regulation is optionally provided.
