Konkret betrifft die Erfindung eine Spritzdüsen-Verstelleinrichtung zur Positionierung zumindest einer Spritzdüse gegenüber einem Strang in einer Strangführung einer Brammen-Stranggießmaschine, aufweisend
- eine Verschiebeeinrichtung, umfassend einen Antriebskörper und einen Stellkolben, zum Verschieben des Stellkolbens gegenüber des feststehenden Antriebskörpers; und
- einen Spritzdüsenhalter zum Haltern von zumindest einer Spritzdüse, wobei die Spritzdüse zum Aufspritzen von Kühlmittel auf den Strang ausgebildet und der Spritzdüsenhalter mit dem Stellkolben verbunden ist.
- a displacement device, comprising a drive body and an actuating piston, for displacing the actuating piston relative to the stationary drive body; and
- a spray nozzle holder for holding at least one spray nozzle, wherein the spray nozzle for spraying coolant formed on the strand and the spray nozzle holder is connected to the actuating piston.
Eine derartige Vorrichtung ist beispielsweise aus der
Die Aufgabe der Erfindung ist es, die Nachteile des Stands der Technik zu überwinden und eine besonders kompakte Spritzdüsen-Verstelleinrichtung der eingangs genannten Art anzugeben, bei der das Kühlmittel betriebssicher, insbesondere ohne den Einsatz von Schlauchleitungen, von der Verschiebeeinrichtung zur Spritzdüse geleitet werden kann; insbesondere sollen auch existierenden Strangführungssegmente mit der Spritzdüsen-Verstelleinrichtung nachgerüstet werden können.The object of the invention is to overcome the disadvantages of the prior art and to provide a particularly compact spray nozzle adjustment device of the type mentioned, in which the coolant can be reliably, in particular without the use of hose lines, passed from the displacement device to the spray nozzle; In particular, existing strand guide segments should also be retrofitted with the spray nozzle adjustment device.
Diese Aufgabe wird durch eine eingangs genannte Vorrichtung gelöst, bei der
- zumindest ein teleskopierbares Teleskoprohr zur Leitung des Kühlmittels vom Antriebskörper zum Spritzdüsenhalter vorgesehen ist, sodass die Spritzdüse drehsteif mit dem Antriebskörper verbunden ist; und
- die Längsachsen des Stellkolbens und des Teleskoprohrs parallel ausgerichtet sind.
- at least one telescopic telescopic tube is provided for guiding the coolant from the drive body to the spray nozzle holder, so that the spray nozzle is torsionally rigidly connected to the drive body; and
- the longitudinal axes of the actuating piston and the telescopic tube are aligned in parallel.
Durch die erfindungsgemäße Vorrichtung wird zum Einen das Kühlmittel mittels eines Teleskoprohrs sehr betriebsicher und vor allem ohne wartungsintensive Schlauchleitungen vom Antriebskörper der Verschiebeeinrichtung zur Spritzdüse - die als eine Einstoff- oder eine Mehrstoffdüse ausgebildet sein kann - geleitet; zum Anderen wird der Spritzdüsenhalter und somit auch die Spritzdüse mittels des Teleskoprohrs drehsteif mit der Verschiebeeinrichtung verbunden, d.h. dass der Spritzdüsenhalter gegen eine Verdrehung gegenüber der Verschiebeeinrichtung gesichert wird. Das Teleskoprohr kann grundsätzlich ein- oder mehrstufig ausgeführt sein. Unter einer einstufigen Ausführung versteht man ein Teleskoprohr
- mit einem feststehenden und einem verschieblichen Rohr, wobei beide Rohre koaxial ausgerichtet sind und das verschiebliche Rohr einen kleineren Durchmesser als das feststehende Rohr aufweist,
- bei dem das verschiebliche Rohr gegenüber dem feststehenden Rohr abgedichtet ist, und
- bei dem das verschiebliche Rohr verschieblich (auch als teleskopierend bezeichnet) gegenüber dem feststehenden Rohr ausgebildet ist, sodass das Teleskoprohr einerseits im eingefahrenen Zustand eine geringe Baulänge aufweist und andererseits, im ausgefahrenen Zustand eine große Baulänge gegeben ist.
- with a fixed and a displaceable tube, wherein both tubes are aligned coaxially and the displaceable tube has a smaller diameter than the fixed tube,
- in which the displaceable tube is sealed from the fixed tube, and
- in which the displaceable tube is designed to be displaceable (also referred to as telescoping) with respect to the stationary tube, so that the telescopic tube has a small overall length in the retracted state and, on the other hand, has a large structural length in the extended state.
Bei einem mehrstufigen Teleskoprohr sind zumindest zwei Rohre verschieblich ausgebildet, sodass eine noch kompaktere Bauweise möglich ist. Sowohl bei einem einstufigen als auch bei einem mehrstufigen Teleskoprohr sind das feststehende Rohr mit dem Antriebskörper und das verschiebliche Rohr (bei einer mehrstufigen Ausführung das letzte verschiebliche Rohr) mit dem Spritzdüsenhalter verbunden. Durch die parallele Ausrichtung des Teleskoprohrs und des Stellkolbens ist es zudem möglich, das Kühlmittels unter Umständen auch mittels mehrerer Teleskoprohre, wobei der Stellkolben und die Teleskoprohre nicht notwendigerweise in einer Ebene liegen müssen, zum Spritzdüsenhalter zu leiten. Durch die kompakte Konstruktion der erfindungsgemäßen Vorrichtung können auch existierende Strangführungssegmente mit einer Spritzdüsen-Verstelleinrichtung (beispielsweise am Innenbogen) nachgerüstet werden.In a multi-stage telescopic tube at least two tubes are designed to be displaceable, so that an even more compact design is possible. Both in a single-stage and in a multi-stage telescopic tube, the fixed tube with the drive body and the sliding tube (in a multi-stage version, the last sliding tube) are connected to the spray nozzle holder. Due to the parallel orientation of the telescopic tube and the actuating piston, it is also possible, the coolant under certain circumstances by means of several telescopic tubes, the control piston and the telescopic tubes do not necessarily have to lie in one plane, to guide the spray nozzle holder. Due to the compact construction of the device according to the invention, existing strand guide segments can also be retrofitted with a spray nozzle adjustment device (for example on the inner arc).
Nach einer vorteilhaften Ausführungsform ist ein erstes Teleskoprohr zur Leitung von Wasser und ein zweites Teleskoprohr zur Leitung von Luft vorgesehen, wobei die Längsachsen des Stellkolbens, des ersten Teleskoprohrs und des zweiten Teleskoprohrs parallel ausgerichtet sind. Dadurch werden sämtliche Medien für eine Zweistoff-Spritzdüse betriebssicher und kompakt vom Antriebskörper der Verschiebeeinrichtung zum Spritzdüsenhalter geleitet.According to an advantageous embodiment, a first telescopic tube for guiding water and a second telescopic tube for guiding air is provided, wherein the longitudinal axes of the actuating piston, the first telescopic tube and the second telescopic tube are aligned in parallel. As a result, all the media for a two-substance spray nozzle Reliable and compact headed by the drive body of the displacement device to the spray nozzle holder.
Nach einer weiteren Ausführungsform, ist ein Faltenbalg mit dem Antriebskörper und dem Spritzdüsenhalter verbunden, wodurch das Eindringen von Schmutz verhindert werden kann. Durch den Faltenbalg wird das Eindringen von Schmutz, z.B. Zunder, unterhalb des Faltenbalgs (z.B. im Bereich der Dichtungen der Verschiebeeinrichtung oder des Teleskoprohrs) verhindert.According to another embodiment, a bellows is connected to the drive body and the spray nozzle holder, whereby the ingress of dirt can be prevented. The bellows prevent the ingress of dirt, e.g. Scale, below the bellows (e.g., in the region of the seals of the displacer or telescopic tube).
Nach einer besonders vorteilhaften Ausführungsform ist dem Faltenbalg eine Luftversorgung, vorzugsweise das zweite Teleskoprohr, zugeordnet, wodurch der Faltenbalg unter einem gegenüber der Atmosphäre erhöhten Druck gehalten werden kann. Durch den erhöhten Druck wird wirkungsvoll das Eindringen von staubförmigen Schmutzpartikeln verhindert.According to a particularly advantageous embodiment, the bellows is associated with an air supply, preferably the second telescopic tube, whereby the bellows can be kept under a pressure which is increased in relation to the atmosphere. The increased pressure effectively prevents the penetration of dusty dirt particles.
Nach einer robusten Ausführungsform umfasst die Verschiebeeinrichtung einen hydraulischen, pneumatischen oder elektrischen Linearantrieb.According to a robust embodiment, the displacement device comprises a hydraulic, pneumatic or electric linear drive.
Nach einer weiteren Ausführungsform ist der hydraulische oder pneumatische Linearantrieb als ein Druckmittelzylinder ausgebildet. Die Verwendung von Druckmittelzylindern ist aufgrund der hohen Betriebstemperaturen in der Nähe des Strangs vorteilhaft.According to a further embodiment, the hydraulic or pneumatic linear drive is designed as a pressure medium cylinder. The use of pressure cylinders is advantageous because of the high operating temperatures in the vicinity of the strand.
Für die Fertigung der Spritzdüsen-Verstelleinrichtung ist es vorteilhaft, wenn der Antriebskörper und ein feststehender Teil zumindest eines Teleskoprohrs ein gemeinsames Gehäuse aufweisen.For the production of the spray nozzle adjustment device, it is advantageous if the drive body and a fixed part of at least one telescopic tube have a common housing.
Nach einer besonders kostengünstigen Ausführungsform ist mehreren Druckmittelzylindern ein hydraulischer oder pneumatischer Mengenteiler zugeordnet, sodass die Position mehrerer Spritzdüsen synchron gesteuert werden kann. Mittels des Mengenteilers ist gewährleistet, dass sämtliche Spritzdüsen synchronisiert eine Soll-Position anfahren und - sollte dies z.B. aufgrund einer Blockade nicht möglich sein - so fahren dennoch die nicht blockierten Spritzdüsen synchron gesteuert eine gemeinsame Position an.According to a particularly inexpensive embodiment, a plurality of pressure medium cylinders, a hydraulic or pneumatic flow divider is assigned, so that the position of several spray nozzles can be controlled synchronously. By means of the flow divider is guaranteed that all Injection nozzles synchronized approach a desired position and - if this is not possible due to a blockade, for example - then non-blocked spray nozzles move synchronously controlled to a common position.
Nach einer Ausführungsform ist zumindest einer, bevorzugt jeder, Spritzdüse genau ein Spritzdüsenhalter und dem Spritzdüsenhalter genau eine Verschiebeeinrichtung zugeordnet, wodurch die Spritzdüse unabhängig positionierbar ist. Dadurch ist eine vollkommen unabhängige Positionierbarkeit der Spritzdüsen möglich.According to one embodiment, at least one, preferably each, spray nozzle is assigned exactly one spray nozzle holder and the spray nozzle holder has exactly one displacement device, whereby the spray nozzle can be positioned independently. This allows a completely independent positioning of the spray nozzles.
Nach einer weiteren Ausführungsform sind zumindest einer Spritzdüse eine Wegmesseinrichtung und eine Regeleinrichtung zugeordnet, wodurch die Spritzdüse geregelt positionierbar ist. Mittels dieser Ausführungsform ist die Spritzdüse hochgenau positionierbar.According to a further embodiment, at least one spray nozzle is associated with a displacement measuring device and a control device, whereby the spray nozzle can be positioned in a regulated manner. By means of this embodiment, the spray nozzle can be positioned with high precision.
Nach einer sehr kostengünstigen Ausführungsform ist mehreren Druckmittelzylindern ein Mengenteiler, der durch mehrere drehzahlgekoppelte Zahnradmotore gebildet wird, ein Drehzahlsensor der einem Zahnradmotor zugeordnet ist, und eine Steuer- bzw. eine Regeleinrichtung zugeordnet, sodass die Position mehrerer Spritzdüsen, die den Druckmittelzylindern zugeordnet sind, synchron eingestellt werden kann. Mittels dieser Ausführungsform wird der Volumenstrom zu den Druckmittelzylindern über den Drehzahlsensor erfasst und mittels der Regeleinrichtung geregelt. Obwohl die Position der Spritzdüsen nicht klassischerweise durch eine Wegmesseinrichtung erfasst werden muss, können dennoch die Spritzdüsen ausreichend genau positioniert werden.According to a very inexpensive embodiment, a plurality of pressure medium cylinders is a flow divider, which is formed by a plurality of speed-coupled gear motors, a speed sensor associated with a gear motor, and associated with a control or a control device, so that the position of a plurality of spray nozzles, which are associated with the pressure medium cylinders, synchronously can be adjusted. By means of this embodiment, the volume flow to the pressure-medium cylinders is detected via the speed sensor and regulated by means of the control device. Although the position of the spray nozzles does not have to be detected conventionally by a displacement measuring device, nevertheless the spray nozzles can be positioned sufficiently accurately.
