Abstract

The method involves selective or linear welding of adjacent plastic plates (1, 2) according to a predetermined welding pattern by laser, infrared or ultrasound. The plastic plates welded with each other are heated. The heated plastic plates are deformed by application of pressurized air and/or vacuum. An outer plate of the plastic plates is deformed during the deformation of the plastic plates. The welding pattern is provided such that passages exist between the plastic plates after the deformation of the plastic plates.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines aus mehreren Kunststoffplatten hergestellten Endproduktes.The The invention relates to a method for producing one of a plurality of plastic plates produced end product.

Aus der DE 297 12 684 U1 ist bereits eine mehrlagige Verbundplatte bekannt, welche wenigstens zwei profilierte, ein Wellenprofil mit auf jeder Seite in einer Ebene liegenden Scheitellinien aufweisende Lagen enthält. Die einzelnen profilierten Lagen sind wellige Kunststoff-Verbundlagen aus einem mehrschichtig extrudierten Verbund. Sie umfassen zwei Außenschichten und eine Mittelschicht aus Polymeren aus der gleichen stofflichen Gruppe. Die Mittelschicht besteht aus einem hochkristallinen Polymer mit eingebauten zugfesten Fasern. Der Schmelzpunkt des Polymers liegt wenigstens 15°C höher als die Schmelzpunkte der Polymere der Außenschichten. Das Elastizitätsmodul des Polymers der Mittelschicht ist um wenigstens 10% geringer als die Elastizitätsmodule der Polymere der Außenschichten. Zwischen wenigstens zwei benachbarten profilierten Lagen ist eine Zwischenplatte eingefügt, die mit den Scheitellinien der daran anliegenden profilierten Lagen verschweißt ist.From the DE 297 12 684 U1 already a multilayer composite panel is known, which contains at least two profiled, having a wave profile with lying on each side in a plane crest lines having layers. The individual profiled layers are wavy plastic composite layers of a multilayer extruded composite. They comprise two outer layers and a middle layer of polymers from the same material group. The middle layer consists of a highly crystalline polymer with built-in tensile fibers. The melting point of the polymer is at least 15 ° C higher than the melting points of the polymers of the outer layers. The modulus of elasticity of the polymer of the middle layer is at least 10% lower than the elastic moduli of the polymers of the outer layers. Between at least two adjacent profiled layers an intermediate plate is inserted, which is welded to the apex lines of the profiled layers adjacent thereto.

Aus der DE 103 43 603 A1 ist eine insbesondere für Trockentransformatoren vorgesehene, wenigstens drei Lagen aus Isoliermaterial aufweisende Isolierplatte bekannt. Diese weist eine gleichförmige Wellenstruktur auf, wobei die Abstände der äußeren Mantellinie der Isolierplatte um die doppelte Wellenamplitude vergrößert sind. Zur Her stellung einer wellenförmig geformten Platte wird eine ebene Isolierplatte in eine Form eingebracht, dort unter Druck in eine Wellenform gebracht, auf 250°C aufgeheizt, für die Dauer einer Stunde auf dieser Temperatur gehalten und danach in der Form abgekühlt. Die derart hergestellte wellenförmige Platte wird auf einer weiteren ebenen Isolierplatte angeordnet und entlang ihrer Wellenrücken mit der benachbarten ebenen Platte verschweißt.From the DE 103 43 603 A1 is known in particular for dry-type transformers, at least three layers of insulating material having insulating known. This has a uniform wave structure, wherein the distances of the outer surface line of the insulating plate are increased by twice the wave amplitude. For the manufacture of a wave-shaped plate a flat insulating plate is placed in a mold, placed there under pressure in a waveform, heated to 250 ° C, held for one hour at this temperature and then cooled in the mold. The wave-shaped plate thus produced is placed on another flat insulating plate and welded along its wave backs with the adjacent flat plate.

Die Aufgabe der Erfindung besteht darin, ein vereinfachtes Verfahren zur Herstellung eines aus mehreren Kunststoffplatten hergestellten Endproduktes anzugeben.The The object of the invention is a simplified method for producing a made of several plastic plates Indicate the end product.

Diese Aufgabe wird durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.These The object is achieved by a method with the specified in claim 1 Characteristics solved. Advantageous embodiments and further developments of Invention are given in the dependent claims.

Die Vorteile der Erfindung bestehen insbesondere darin, dass im Vergleich zu bekannten Verfahren die Anzahl der Verarbeitungsschritte reduziert ist. Insbesondere kann eine Verformung der Kunststoffplatten nach erfolgter punktueller oder linearer Verschweißung und Erwärmung der Kunststoffplatten in einem einzigen Arbeitsschritt erfolgen. Dieser Arbeitsschritt erfolgt vorzugsweise unter Verwendung einer Doppelform, in welche die miteinander verschweißten und erwärmten und damit hinreichend verformungsfähigen Kunststoffplatten eingesetzt werden. Die Formgebung der Doppelform selbst ist so gewählt, dass die Außenplatten des aus mehreren Kunststoffplatten hergestellten Endproduktes eine jeweils gewünschte Form aufweisen. Diese kann eben sein oder auch ein jeweils gewünschtes anderes Profil aufweisen. Die Verformung erfolgt in vorteilhafter Weise durch ein Einbringen von Druckluft und/oder einem Vakuum in die Doppelform. Die Doppelform ist dabei so ausgestaltet, dass entsprechende Düsen eines Druckluftgerätes bzw. eines Vakuumerzeugers an den gewünschten Stellen der miteinander verschweißten und erwärmten Kunststoffplatten positioniert werden können.The Advantages of the invention are, in particular, that in comparison to known methods, the number of processing steps is reduced. In particular, a deformation of the plastic plates after completed spot or linear welding and heating the plastic plates done in a single step. This operation is preferably carried out using a Double form, in which the welded together and heated and thus sufficiently deformable Plastic plates are used. The shape of the double shape itself is chosen so that the outer plates of the made of several plastic plates finished product one each have desired shape. This can be flat or too each have a different desired profile. The deformation takes place in an advantageous manner by introducing compressed air and / or a vacuum in the double mold. The double form is included designed so that corresponding nozzles of a compressed air device or a vacuum generator at the desired locations of welded together and heated plastic plates can be positioned.

Durch ein geeignetes Dosieren von Druckluft und/oder Vakuum und eine geeignete Wahl der einzelnen Kunststoffplatten, die entweder gleiche oder unterschiedliche Stärken aufweisen, aus demselben oder unterschiedlichen Materialen bestehen und denselben oder unterschiedliche Schmelzpunkte aufweisen, und eine geeignete Vorgabe des Schweißmusters kann eine Vielzahl verschiedenartiger Endprodukte hergestellt werden.By a suitable dosing of compressed air and / or vacuum and a suitable Choice of individual plastic sheets, either the same or different Have strengths, from the same or different Materials exist and the same or different melting points and a suitable specification of the welding pattern a variety of different end products can be produced.

Beispielsweise können die Außenplatten eben verlaufen und eine oder mehrere innenliegende Platten eine Zickzack- oder eine Wellenform haben. Die Wellen mehrerer innenliegender Platten können parallel zueinander oder im rechten Winkel zueinander verlaufen. Ferner können die Außenplatten auch eine gewünschte profilierte Form haben, die von der beabsichtigten Anwendung des jeweiligen Endproduktes abhängig ist.For example the outer plates can run flat and one or more internal plates a zigzag or a wave shape to have. The waves of several internal plates can be parallel to each other or at right angles to each other. Furthermore, can the outer panels also profiled a desired Have the form of the intended application of each End product is dependent.

Mit dem erfindungsgemäßen Verfahren hergestellte Endprodukte weisen eine hohe Stabilität auf und haben ein vergleichsweise geringes Gewicht. Sie sind beispielsweise bei Produkten im Drainsegmentbereich, für leichte, aber dennoch stabil tragende Verpackungsteile und bei Trägerteilen in der Automobilindustrie verwendbar.With end products prepared by the process according to the invention have a high stability and have a comparatively low weight. They are, for example, products in the drain segment area, For lightweight, yet sturdy carrying parts and usable in carrier parts in the automotive industry.

Je nach Material der einzelnen Kunststoffplatten und der angewendeten Temperatur können die einzelnen Kunststoffplatten, die unterschiedliche Schmelzpunkte aufweisen können, unterschiedlich leicht verformbar sein.The be welded together so plastic plates heated in the next processing step, so that in a desired soft deformable processing state reach. Depending on the material of the individual plastic plates and the applied temperature, the individual plastic plates, which may have different melting points, different degrees of lightness be deformable.

Sind die Kunststoffplatten durch die Beaufschlagung mit der gewünschten Temperatur in den verformbaren Zustand gebracht, dann erfolgt ein Einsetzen der Kunststoffplatten in eine Doppelform und eine Verformung der Kunststoffplatten durch ein Einbringen von Druckluft und/oder ein Vakuum in die Doppelform, wobei Druckluft in die Bereiche zwischen einander benachbarten Kunststoffplatten eingebracht und Vakuum im Bereich der Außenseiten der äußeren Kunststoffplatten erzeugt wird.are the plastic plates by applying the desired Temperature brought into the deformable state, then takes place Insert the plastic sheets in a double mold and a deformation the plastic plates by introducing compressed air and / or a vacuum in the double mold, with compressed air in the areas between introduced adjacent plastic plates and vacuum in the Area of the outer sides of the outer plastic plates is produced.

Die Doppelform selbst kann an ihren Innenflächen glatt oder profiliert ausgebildet sein.The Double form itself can be smooth or smooth on its inner surfaces be formed profiled.

Sind die Innenflächen der Doppelform glatt ausgebildet, dann wird durch die Anwendung von Druckluft und/oder Va kuum beispielsweise ein Endprodukt hergestellt, wie es in der 3 gezeigt ist. Bei diesem Endprodukt haben die beiden Außenplatten 1 und 3 jeweils einen glatten, ebenen Verlauf. Die zwischen den beiden Außenplatten 1 und 3 positionierte innenliegende Kunststoffplatte 2 ist durch die Anwendung von Druckluft derart verformt, dass sie einen zickzackförmigen Verlauf hat. Die Kunststoffplatte 2 ist nach der genannten Verformung nach wie vor sowohl mit der Kunststoffplatte 1 als auch mit der Kunststoffplatte 3 punktuell bzw. linear verschweißt. Bei diesem Ausführungsbeispiel wurde das ursprüngliche Schweißmuster derart gewählt, dass durch das Verformen in einer Richtung senkrecht zur Zeichenebene verlaufende Kanäle gebildet werden.Are the inner surfaces of the double shape smooth, then by the use of compressed air and / or vacuum Va example, a final product is produced, as in the 3 is shown. In this final product, the two outer plates 1 and 3 each a smooth, even course. The between the two outer plates 1 and 3 positioned inside plastic plate 2 is deformed by the application of compressed air so that it has a zigzag course. The plastic plate 2 is after the said deformation still with both the plastic plate 1 as well as with the plastic plate 3 selectively or linearly welded. In this embodiment, the original welding pattern was chosen such that channels formed by the deformation in a direction perpendicular to the plane of the drawing are formed.

Bei dem in der 3 gezeigten Ausführungsbeispiel ist der Schmelzpunkt des Materials, aus welchem die Kunststoffplatten 1 und 3 bestehen, vorzugsweise größer gewählt als der Schmelzpunkt des Materials, aus dem die Kunststoffplatte 2 besteht. Durch das Erwärmen auf eine geeignete Temperatur kann dann insbesondere in Verbindung mit den glatten Innenflächen der Doppelform sichergestellt werden, dass die beiden Außenplatten 1 und 3 die gewünschte glatte Form aufweisen, während die innenliegende Kunststoffplatte 2 die in der 3 veranschaulichte Zickzackform erhält.In the in the 3 embodiment shown is the melting point of the material from which the plastic plates 1 and 3 exist, preferably chosen larger than the melting point of the material from which the plastic plate 2 consists. By heating to a suitable temperature can then be ensured in particular in conjunction with the smooth inner surfaces of the double mold, that the two outer plates 1 and 3 have the desired smooth shape, while the inner plastic plate 2 the in the 3 illustrated zigzag shape gets.

Nach dem Verformen und anschließender Abkühlung liegt das gewünschte Endprodukt vor.To the deformation and subsequent cooling is the desired end product.

Sind die Innenflächen der Doppelform hingegen profiliert ausgebildet, dann wird durch die Anwendung von Druckluft und/oder Vakuum beispielsweise ein Endprodukt hergestellt, wie es in der 4 gezeigt ist. Bei diesem Endprodukt hat die innenliegende Kunststoffplatte 2 ebenso wie in der 3 einen zickzackförmigen Verlauf. Die Form der beiden Außenplatten 1 und 3 passt sich aufgrund der Anwendung von Druckluft und/oder Vakuum an die Form gebung der Innenflächen der Doppelform an, so dass das schließlich hergestellte Endprodukt nicht nur eine profilierte innenliegende Kunststoffplatte 2 aufweist, sondern auch profilierte Außenplatten 1 und 3.If the inner surfaces of the double mold, however, formed profiled, then by the application of compressed air and / or vacuum, for example, a final product is produced, as in the 4 is shown. In this end product has the inner plastic plate 2 as well as in the 3 a zigzag course. The shape of the two outer panels 1 and 3 Adjusts due to the application of compressed air and / or vacuum to the shape environment of the inner surfaces of the double mold, so that the final product finally produced not only a profiled inner plastic plate 2 has, but also profiled outer panels 1 and 3 ,

Die vorliegende Erfindung beschreibt nach alledem ein Verfahren zur Herstellung eines aus mehreren Kunststoffplatten hergestellten Endproduktes, bei welchem jeweils zwei benachbarte Kunststoffplatten punktuell oder linear miteinander verschweißt werden. Danach erfolgt eine Erwärmung der miteinander verschweißten Kunststoffplatten. Aus den miteinander verschweißten, erwärmten Kunststoffplatten wird durch eine Anwendung von Druckluft und/oder Vakuum, welche vorzugsweise in einer Doppelform erfolgt, das jeweils gewünschte Endprodukt hergestellt. Die Form des Endproduktes ist abhängig von dem jeweils verwendeten Schweißmuster, von den Orten der Anwendung von Druckluft und/oder Vakuum, von der Stärke der angewendeten Druckluft bzw. des angewendeten Vakuums und von der Formgebung der jeweils verwendeten Doppelform. Die Form des Schweißmusters kann beispielsweise derart vorgegeben werden, dass das Endprodukt Kanäle, Rippen und/oder Versteifungspunkte aufweist.The The present invention, after all, describes a method for Production of an end product made of several plastic sheets, in which each two adjacent plastic plates punctually or welded together linearly. After that takes place a heating of the welded together plastic plates. Out the welded together, heated plastic plates is caused by an application of compressed air and / or vacuum preferably in a double form, the respectively desired end product produced. The shape of the final product depends on the welding pattern used, from the locations of the Application of compressed air and / or vacuum, of the strength the applied compressed air or the applied vacuum and the Shaping the double shape used in each case.
