Abstract
Description
Die Erfindung betrifft eine Kalibriereinrichtung zum Kalibrieren des
Durchmessers extrudierter Rohre,
die ein Kalibrierungsrohr und
Mittel zum Verändern des Durchmessers des Kalibrierungsrohres
aufweist,
wobei die Mittel zum Verändern des Durchmessers des
Kalibrierungsrohres mindestens zwei zur Extrusionsachse parallele
Stangen umfasst, deren relativer Abstand zueinander veränderbar ist.
The invention relates to a calibration device for calibrating the diameter of extruded pipes,
which is a calibration tube and
Has means for changing the diameter of the calibration tube,
wherein the means for changing the diameter of the calibration tube comprises at least two rods parallel to the extrusion axis, the relative distance between which can be changed.
Gattungsgemäße Kalibriereinrichtungen sind allgemein bekannt und dienen der Sicherstellung einer gleichbleibenden Qualität von extrudierten Kunststoffsträngen, insbesondere Kunststoffrohren. Nach der Extrusion des Kunststoffstranges ist es erforderlich, dessen gewünschte Kontur zu halten, bis der Strang eine selbsttragende Konsistenz aufweist. Hierzu dienen die bekannten Kalibriereinrichtungen. Der pastöse Strang wird im allgemeinen in der Kalibriereinrichtung, die die gewünschte Kontur aufweist, an dessen Wandung mittels Vakuum gezogen. Es kommen hier sogenannte Naß- und Trockenkalibriereinrichtungen zum Einsatz. Generic calibration devices are generally known and serve to ensure a constant quality of extruded plastic strands, especially plastic pipes. After Extrusion of the plastic strand is necessary, the desired one Keep contour until the strand has a self-supporting consistency. The known calibration devices are used for this purpose. The pasty strand is generally in the calibration facility that the desired Has contour, drawn on the wall by vacuum. It so-called wet and dry calibration devices are used here Commitment.
Durch Verwendung verschiedener Werkstoffe, aber auch durch Einflußparameter wie Temperatur, kommt es zu Veränderungen der Durchmesser der Kalibriervorrichtungen oder sie muß für das Erreichen der gewünschten Abmasse verändert werden. By using different materials, but also by Influencing parameters such as temperature, there are changes in the Diameter of the calibration devices or they must be used to achieve the desired dimensions can be changed.
Aus der DE 200 00 872 ist eine Kalibriereinrichtung bekannt, bei der eine geschlitzte Hülse mittels einer Art Schlauchklemme zusammen geschnürt wird. Dies hat den Nachteil, dass die Hülse nur in ihrem Zentrum im Durchmesser verändert werden kann, da der Längsschlitz die Hülse nicht komplett auftrennt, sondern am Anfang und am Ende einen durchgängigen Kreisquerschnitt besitzt. Hierdurch erweitert sich der Durchmesser zum Ende der Hülse, wodurch der Verstellbereich stark eingeschränkt ist. From DE 200 00 872 a calibration device is known in which a slotted sleeve together using a kind of hose clamp is laced. This has the disadvantage that the sleeve is only in its Center can be changed in diameter because the longitudinal slot Do not cut open the sleeve completely, but one at the beginning and at the end has a continuous circular cross-section. This expands the Diameter to the end of the sleeve, making the adjustment range strong is restricted.
Die EP 825 920 bietet eine andere Lösung an, hier wird über Keil- Klemmstangen, die gegeneinander verschoben werden, der Durchmesser einer Mehrzahl von Spaltringelementen, die zusammen eine Röhre bilden, verändert. Der Einsatz von Keil-Klemmstangen hat jedoch den Nachteil, dass relativ hohe Verstellkräfte erforderlich sind, da die Reibung der Stangen zueinander überwunden werden muss. Weiterhin ist die Fertigung von Keilstangen aufwendig. EP 825 920 offers a different solution. Clamping rods that are shifted against each other, the diameter a plurality of split ring elements that together form a tube form, changed. However, the use of wedge clamps has that Disadvantage that relatively high adjustment forces are required because the Friction between the rods must be overcome. Furthermore is the production of wedge bars is expensive.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung anzubieten, bei der eine Verstellung des Durchmessers einer Kalibriereinrichtung mit einfachen Mittels erfolgen kann, ohne dass hohe Verstellkräfte erforderlich sind. The object of the present invention is a device to offer, in which an adjustment of the diameter of one Calibration device can be done with simple means without high Adjustment forces are required.
Die Lösung der Aufgabe ist in Verbindung mit dem Oberbegriff des Anspruchs 1 durch Verbindungselemente, die den relativen Abstand der Stangen verändern können, gekennzeichnet. The solution to the problem is in connection with the Preamble of claim 1 by connecting elements, the relative Distance of the bars can be marked.
Vorteilhafte Weiterbildungen sind in den Unteransprüchen wiedergegeben. Advantageous further developments are in the subclaims played.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. In the drawing, an embodiment of the invention is schematic shown.
Die Figur zeigt den Halbschnitt einer Kalibriereinrichtung mit einem Kalibrierungsrohr 1, das durch eine Kalibrierungshülse 9 gebildet wird. Die Kalibrierungshülse 9 ist spiralförmig geschlitzt und somit eine offene Hülse, die wie eine Spiralfeder wirkt. Der Schlitz 10 hat eine relativ große Steigung, es ist aber auch denkbar, einen Schlitz mit geringerer Steigung einzubringen und dann das Kalibrierungsrohr 1 aus einer durchgehenden Kalibrierungshülse 9 (analog einer Spiralfeder) oder einer Mehrzahl von entlang der Extrusionsachse 4 hintereinander, also in Reihe, angeordneten geschlitzten Kalibrierungshülsen 9 zu bilden. The figure shows the half section of a calibration device with a calibration tube 1 , which is formed by a calibration sleeve 9 . The calibration sleeve 9 is slit spirally and thus an open sleeve that acts like a coil spring. The slot 10 has a relatively large slope, but it is also conceivable to introduce a slot with a smaller slope and then the calibration tube 1 from a continuous calibration sleeve 9 (analogous to a spiral spring) or a plurality of one behind the other, that is in series, along the extrusion axis 4 , arranged to form slotted calibration sleeves 9 .
Zur Veränderung des Durchmessers des Kalibrierungsrohres 1, in diesem Ausführungsbeispiel der Kalibrierungshülse 9, sind zwei parallel zur Extrusionsachse 4 angeordnete Stangen 5 und 6 vorgesehen, die über Verbindungselemente 8 funktional in Verbindung stehen. Durch Verdrehen der Gewindemutter 12 wird die äußere Stange 5 axial verschoben. Die Verschiebung erfolgt relativ zu den in der Kalibriereinrichtung angeordneten Stützelementen 13. Durch die Stützelemente 13 werden all die Freiheitsgrade eliminiert, die nicht für die Verstellung benötigt werden. To change the diameter of the calibration tube 1 , in this exemplary embodiment the calibration sleeve 9 , two rods 5 and 6 are provided which are arranged parallel to the extrusion axis 4 and are functionally connected via connecting elements 8 . By turning the threaded nut 12 , the outer rod 5 is axially displaced. The displacement takes place relative to the support elements 13 arranged in the calibration device. The support elements 13 eliminate all the degrees of freedom that are not required for the adjustment.
Durch das Verschieben der Stange 5 wird der Winkel 3 der Verbindungselemente 8 zur Extrusionsachse 4 verändert, was eine radiale Bewegung der Stange 6 zur Folge hat. Dieser radiale Druck auf die Kalibrierungshülse 9 bewirkt ein Zusammenschnüren dieser und folglich eine Verringerung des Durchmessers. By moving the rod 5 , the angle 3 of the connecting elements 8 to the extrusion axis 4 is changed, which results in a radial movement of the rod 6 . This radial pressure on the calibration sleeve 9 causes it to constrict and consequently to reduce the diameter.
Die Kalibrierungshülse 9 ist mit Öffnungen 11 versehen, damit ein angelegtes Vakuum auf das zu kalibrierende Rohr wirken kann. Beim Einsatz mehrerer Kalibrierungshülsen 9 oder einer mit geringer Steigung des Schlitzes 10, wie oben beschrieben, kann auf die Vakuumöffnungen 11 verzichtet werden, da über die Schlitze 10 ausreichend Vakuum angelegt wird. The calibration sleeve 9 is provided with openings 11 so that an applied vacuum can act on the pipe to be calibrated. When using several calibration sleeves 9 or one with a slight slope of the slot 10 , as described above, the vacuum openings 11 can be dispensed with, since sufficient vacuum is applied via the slots 10 .
Ein wirksamerer Effekt der Durchmesserveränderung wird erzielt, wenn
das parallele Stangenpaar 5 und 6 mehrfach gleichmäßig um die
Extrusionsachse in der Kalibriereinrichtung angeordnet ist.
