Abstract

Each water bath (T1) holding the sizing dies has end walls where it is joined to the next water bath. The end walls are fitted with locating recesses and projections placed so as to be symmetric in plan view about a vertical axis. The lid hinges and closing clamps can be attached on either side wall so that the lid is reversible. Connections are provided on both sides of the bath. A series of baths is arranged with cooling water alternately in contra-flow or in parallel flow with the extrusion. The sizing dies and end walls can accordingly be fitted in alternate positions.

Description

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 und zu kalibrieren, wobei an den Stirnwänden Zentriervorsprünge und Zentriervertiefungen angeordnet sind.The The invention relates to a device for calibrating and cooling Plastic profiles, consisting of at least one tub with a first end wall and a second end wall in which openings provided for the passage of the plastic profile to be processed are, and with screens, which are arranged between the end walls to the plastic profile respectively and to calibrate, wherein at the end walls centering projections and Centering recesses are arranged.

Zur Produktion von Kunststoffprofilen werden Extrusionslinien verwendet, die grundsätzlich aus einem Extruder mit einer Extrusionsdüse, einer Trockenkalibriereinrichtung und einer daran 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 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 Gleichstrom oder im Gegenstrom möglich, was je nach Einsatzfall entsprechend ausgewählt wird. Die Wanne wird an Vakuumpumpen angeschlossen, um im Inneren einen Unterdruck zu erzeugen, der gewährleistet, dass sich das Profil an die Kalibrierblenden anlegt. Dieser Unterdruck wird in der Regel auch zur Förderung des Kühlmediums verwendet, wobei eine Druckdifferenz in Kühlmedienförderrichtung dabei erforderlich ist.to Production of plastic profiles, extrusion lines are used the basically off an extruder with an extrusion die, a dry calibrator and an adjoining one Wet calibration consist. Furthermore, such an extrusion line usually has a caterpillar take-off and a saw for separating profile sections. The wet calibration device is in general from several calibration wells, in which the from the Dry calibrator emerging profile through a water bath to be led and finally chilled becomes. To the leadership and Calibration of the plastic profile are in the tub in predetermined intervals Calibration diaphragms arranged, each having an opening that the outer contour corresponds to the profile. The cooling medium, usually Water, within the tub is controlled by appropriate longitudinal pumps Circulated tub, being through corresponding openings Turbulences are generated in the calibration diaphragms that affect the cooling effect improve. Depending on the direction of the circulation is a cooling in the DC or in countercurrent, which is selected depending on the application. The tub is on Vacuum pump connected to generate a negative pressure inside, which ensures that the profile applies to the calibration diaphragm. This negative pressure is usually also for promotion of the cooling medium used, wherein a pressure difference in Kühlmedienförderrichtung required is.

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 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.conventional Tubs are due to their structural design either for cooling in DC or for a cooling formed in countercurrent. A change is in this regard only through radical reconstruction possible. Furthermore, form several wells lying one behind the other one for the cooling process required correspondingly long calibration distance. It turns out that in each case the same arrangement of the tubs with counter- or DC cooling at the contact surfaces the adjacent wells is a pressure difference. These Pressure difference leads often to impairments smoothness in production.

Aufgabe der vorliegenden Erfindung ist es, die Vorrichtung der oben beschriebenen Art so weiterzubilden, dass sie vielseitig einsetzbar ist und mit geringst möglichem Aufwand hinsichtlich des Kühlprinzips veränderbar ist und eine wesentliche Verbesserung der Laufruhe ermöglicht.task It is the object of the present invention to provide the device of the above-described To further develop art so that it is versatile and with minimal possible Effort in terms of the cooling principle variable is and allows a significant improvement in smoothness.

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.According to the invention solved these tasks by that the centering projections and the centering recesses on both end walls in the plan view similar are arranged and that respect a vertical in use position central axis of each end wall symmetrical a centering recess is arranged for each centering projection.

Wesentlich an der vorliegenden Erfindung ist, dass jede einzelne Wanne grundsätzlich beidseitig verwendbar ist, d.h., dass durch eine Drehung von 180° die stromaufwärtige Stirnfläche zur stromabwärtigen Stirnfläche gemacht werden kann und umgekehrt.Essential In the present invention, each individual tray is basically bilateral is usable, that is, by a rotation of 180 °, the upstream end face to downstream face can be made and vice versa.

Eine alternative Möglichkeit, wahlweise eine Kühlwirkung im Gegen- bzw. Gleichstrom zu ermöglichen 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.A alternative possibility optionally a cooling effect to allow in counter or direct current would be the double arrangement of Water and vacuum connections on the side walls the tubs. However, this has the disadvantage of the consequence that each connection device represents a cost factor, and a vulnerability (insufficient Tightness), which leads to an increased demand for energy for production the negative pressure leads.

Eine Verbesserung der Laufruhe im Produktionsbetrieb wird dadurch ermöglicht, dass die Druckdifferenzen an den Kontaktflächen aneinandergereihter Wannen eliminiert werden, was dadurch ermöglicht wird, dass die jeweils aufeinander folgenden Wannen abwechselnd im Gegen- und Gleichstrom betrieben werden.A Improvement of smoothness in production operation is made possible by that the pressure differences at the contact surfaces of juxtaposed tubs be eliminated, which is made possible by the fact that each successive wells alternately operated in counter and direct current become.

In den Wannen sind die Blenden steckbar angeordnet, sodass die Blenden an die jeweilige Extrusionsrichtung – durch ebenfalls eine 180° Drehung – angepasst werden können. Dies gilt sowohl für die Blenden in den Wannen als auch für jene Blenden, die die Stirnwände der Wannen bilden.In The panels are arranged pluggable, so the panels adapted to the respective extrusion direction - also by a 180 ° rotation can be. This applies to both the panels in the tubs as well as for those screens that are the end walls of the Form tubs.
