Die Erfindung betrifft eine Vorrichtung zum Kalibrieren und Kühlen von Kunststoffprofilen, bestehend aus mindestens einer Wanne mit einer ersten Stirnwand und einer zweiten Stirnwand, in denen Öffnungen zum Durchtritt des zu bearbeitenden Kunststoffprofils vorgesehen sind, und mit Blenden, die zwischen den Stirnwänden angeordnet sind, um das Kunststoffprofil zu führen 5 und zu kalibrieren, wobei an den Stirnwänden Zentriervorsprünge und Zentriervertiefungen angeordnet sind.The invention relates to a device for calibrating and cooling of plastic profiles, comprising at least one trough having a first end wall and a second end wall, in which openings are provided for the passage of the plastic profile to be processed, and with diaphragms which are arranged between the end walls to to guide the plastic profile 5 and to calibrate, wherein centering projections and centering recesses are arranged on the end walls.
Zur Produktion von Kunststoffprofilen werden Extrusionslinien verwendet, die grundsätzlich aus einem Extruder mit einer Extrusionsdüse, einer Trockenkalibriereinrichtung und einer daran io anschließenden Nasskalibriereinrichtung bestehen. Weiters weist eine solche Extrusionslinie üblicherweise einen Raupenabzug und eine Säge zum Abtrennen von Profilabschnitten auf. Die Nasskalibriereinrichtung besteht im Allgemeinen aus mehreren Kalibrierwannen, in denen das aus der Trockenkalibriereinrichtung austretende Profil durch ein Wasserbad geführt wird und damit endgültig abgekühlt wird. Zur Führung und Kalibrierung des Kunststoffprofils sind in der 15 Wanne in vorbestimmten Abständen Kalibrierblenden angeordnet, die jeweils eine Öffnung aufweisen, die der Außenkontur des Profils entspricht. Das Kühlmedium, üblicherweise Wasser, innerhalb der Wanne wird durch entsprechende Pumpen in Längsrichtung der Wanne umgewälzt, wobei durch entsprechende Öffnungen in den Kalibrierblenden Turbulenzen erzeugt werden, die die Kühlwirkung verbessern. Je nach Richtung der Umwälzung ist eine Kühlung im 20 Gleichstrom oder im Gegenstrom möglich, was je nach Einsatzfall entsprechend ausgewählt wird. Die Wanne wird an Vakuumpumpen angeschlossen, um im Inneren einen Unterdrück zu erzeugen, der gewährleistet, dass sich das Profil an die Kalibrierblenden anlegt. Dieser Unterdrück wird in der Regel auch zur Förderung des Kühlmediums verwendet, wobei eine Druckdifferenz in Kühlmedienförderrichtung dabei erforderlich ist. 25For the production of plastic profiles extrusion lines are used, which basically consist of an extruder with an extrusion die, a dry calibration device and an adjoining thereto Naßkalibriereinrichtung. Furthermore, such an extrusion line usually has a caterpillar take-off and a saw for separating profile sections. The wet calibration device generally consists of several calibration troughs, in which the profile emerging from the dry calibration device is passed through a water bath and thus finally cooled. For guiding and calibrating the plastic profile, calibrating diaphragms are arranged in the tub at predetermined intervals, each having an opening which corresponds to the outer contour of the profile. The cooling medium, usually water, within the tub is circulated by respective pumps in the longitudinal direction of the tub, wherein turbulence is generated by corresponding openings in the calibration diaphragms, which improve the cooling effect. Depending on the direction of the circulation, a cooling in 20 DC or in countercurrent is possible, which is selected depending on the application accordingly. The tub is connected to vacuum pumps to create a negative inside which ensures that the profile fits against the calibration blades. This suppression is usually used to promote the cooling medium, with a pressure difference in the cooling medium conveying direction is required. 25
Herkömmliche Wannen sind aufgrund ihres konstruktiven Aufbaus entweder für eine Kühlung im Gleichstrom oder für eine Kühlung im Gegenstrom ausgebildet. Eine Änderung ist diesbezüglich nur durch tiefgreifende Umbaumaßnahmen möglich. Des weiteren bilden mehrere Wannen dicht hintereinander liegend eine für den Abkühlvorgang erforderliche entsprechend lange 30 Kalibrierstrecke. Dabei zeigt sich, dass bei einer jeweils gleichen Anordnung der Wannen mit Gegen- bzw. Gleichstromkühlung an den Kontaktflächen der jeweils benachbarten Wannen eine Druckdifferenz besteht. Diese Druckdifferenz führt vielfach zu Beeinträchtigungen der Laufruhe im Produktionsbetrieb. 35 Aufgabe der vorliegenden Erfindung ist es, die Vorrichtung der oben beschriebenen Art so weiterzubilden, dass sie vielseitig ersetzbar ist und mit geringst möglichem Aufwand hinsichtlich des Kühlprinzips veränderbar ist und eine wesentliche Verbesserung der Laufruhe ermöglicht. 40 Erfindungsgemäß werden diese Aufgaben dadurch gelöst, dass die Zentriervorsprünge und die Zentriervertiefungen an beiden Stirnwänden in der Draufsicht gleichartig angeordnet sind und dass bezüglich einer in Gebrauchslage senkrechten Mittelachse jeder Stirnwand symmetrisch zu jedem Zentriervorsprung eine Zentriervertiefung angeordnet ist. 45 Wesentlich an der vorliegenden Erfindung ist, dass jede einzelne Wanne grundsätzlich beidseitig verwendbar ist, das heißt, dass durch eine Drehung von 180° die stromaufwärtige Stirnfläche zur stromabwärtigen Stirnfläche gemacht werden kann und umgekehrt.Conventional trays are designed either for a cooling in the DC or for a countercurrent cooling due to their structural design. A change in this regard is possible only through radical reconstruction. Furthermore, several wells lying one behind the other form a correspondingly long 30 calibration distance required for the cooling process. It turns out that with a respective same arrangement of the wells with counter or DC cooling at the contact surfaces of each adjacent wells there is a pressure difference. This pressure difference often leads to impairment of smoothness in production. 35 object of the present invention is to develop the device of the type described above so that it is versatile replaceable and can be changed with the least possible effort in terms of cooling principle and allows a substantial improvement in smoothness. According to the invention, these objects are achieved in that the centering projections and the centering recesses are arranged identically on both end walls in plan view and that a centering recess is arranged symmetrically to each centering projection relative to a central axis of each end wall perpendicular to the use position. It is essential to the present invention that each individual tub is basically usable on both sides, that is to say that by a rotation of 180 ° the upstream end face can be made to the downstream end face and vice versa.
Eine alternative Möglichkeit, wahlweise eine Kühlwirkung im Gegen- bzw. Gleichstrom zu er-50 möglichen wäre die doppelte Anordnung von Wasser- und Vakuumanschlüssen an den Seitenwänden der Wannen. Dies hat jedoch den Nachteil zur Folge, dass jede Anschlussvorrichtung einen Kostenfaktor darstellt, und eine Schwachstelle (mangelnde Dichtheit) darstellt, die zu einem Mehrbedarf an Energie zur Erzeugung des Unterdruckes führt. 55 Eine Verbesserung der Laufruhe im Produktionsbetrieb wird dadurch ermöglicht, dass dieAn alternative possibility, optionally a cooling effect in the counter or direct current to 50 possible would be the double arrangement of water and vacuum connections on the side walls of the tubs. However, this has the disadvantage that each connection device represents a cost factor, and represents a weak point (lack of tightness), which leads to an increased demand for energy for generating the negative pressure. 55 An improvement in smoothness in production is made possible by the fact that the
