Description

Die Erfindung richtet sich auf ein Verfahren und eine Vorrichtung zur Herstellung eines thermisch getrennten Verstärkungsprofiles, insbesondere für Fenster- und Türrahmen, wobei zwischen zwei Metallprofilen eine die thermische Trennung bewirkende Kunststoffeinlage vorgesehen ist.The invention is directed to a method and an apparatus for producing a thermally separated reinforcing profile, in particular for window and door frames, wherein between two metal profiles a thermal separation causing plastic insert is provided.

Derartig thermisch getrennte Profile sind in unterschiedlichen Gestaltungen bekannt. So beispielsweise aus der DD 201 655 A , DE 100 33 861 A , DE 20 2004 017 181 U , um nur einige Beispiele zu nennen.Such thermally separated profiles are known in different designs. For example, from the DD 201 655 A . DE 100 33 861 A . DE 20 2004 017 181 U just to name a few examples.

Aus diesen Literaturstellen ist zum Teil bekannt, zunächst über Stege verbundene Profile mit einer Kunststoffeinlage im Bereich des Steges durch Einspritzen des Kunststoffes und Aushärten herzustellen, wobei dann der Steg, der für sich eine thermische Brücke bildet, entfernt wird. Auch ist es bekannt, fertige Kunststoffelemente zwischen zwei Metallprofile einzuclipsen, um die thermische Trennung zu bewirken.From these references it is sometimes known to first produce webs connected profiles with a plastic insert in the region of the web by injecting the plastic and curing, in which case the web, which forms a thermal bridge for itself, is removed. It is also known einzuclipsen finished plastic elements between two metal profiles to effect the thermal separation.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren und eine Vorrichtung anzugeben, mit der im kontinuierlichen Durchlauf thermisch getrennte Verstärkungsprofile herstellbar sind, die beispielsweise bei Fenster und Türen als Verstärkungsprofile herangezogen werden können.The object of the present invention is to provide a method and a device with which in a continuous pass thermally separated reinforcing profiles can be produced, which can be used for example in windows and doors as reinforcement profiles.

Diese Profile können selbstverständlich auch für andere Einsatzzwecke benutzt werden, etwa für den Einsatz beim Bau von Wintergärten, Gewächshäusern, Klimageräten od. dgl.These profiles can of course be used for other purposes, such as for use in the construction of conservatories, greenhouses, air conditioners od. Like.

Mit einem Verfahren der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, dass zwei mit einem senkrecht zur Hauptfläche ausgebildeten Randsteg versehene Metallprofile im Wege der Kaltverformung hergestellt werden, wobei die Randprofile mit einer zur Hauptfläche weisenden Rückkröpfung versehen werden, nachfolgend die Metallprofile einander gegenüber positioniert werden und zwischen die Randprofile im kontinuierlichen Durchlauf ein schnell härtender Kunststoff eingespritzt wird.With a method of the type described is this Problem solved according to the invention in that two provided with a perpendicular to the main surface edge web metal profiles are made by cold deformation, the edge profiles are provided with a pointing to the main surface Rückkröpfung, subsequently the metal profiles are positioned opposite each other and between the edge profiles in the continuous Pass a fast-curing plastic is injected.

Aus der gattungsbildenden DD 201 655 ist eine Verfahrensweise bekannt, bei der zunächst ein entsprechendes Leichtmetallprofil, welches mit einem die Auflage für den Kunststoff bildenden Überbrückungssteg versehen ist, ausgespritzt wird. Dabei ist dort auch beschrieben, dass das Metallprofil eine Mehrzahl von Überbrückungsstegen aufweisen kann, die dann die Auflage für die Kunststoffstege bei deren Herstellung bilden, wobei alle diese Metallstege nacheinander entfernt werden müssen.From the generic DD 201 655 is known a procedure in which initially a corresponding light metal profile, which is provided with a support for the plastic forming bridging web, is injected. It is also described there that the metal profile may have a plurality of bridging webs, which then form the support for the plastic webs during their production, all of these metal webs must be removed one after the other.

Die vorliegende Erfindung hat den Vorteil, dass im kontinuierlichen Durchlaufverfahren im Wege der Kaltverformung zunächst die beiden Metallprofile gebildet werden, diese werden dann zusammengeführt, entsprechend positioniert und folgend wird dann der Spalt bzw. die Lücke zwischen dem Metallprofil mit Kunststoff ausgespritzt. Dabei können die Metallprofile so positioniert werden, dass ihre Randstege auf einer Auflagefläche gleiten, die z.B. mit Dieselöl oder fettlöslicher Flüssigkeit gegen das Anhaften von Kunststoff präpariert wurde, so dass ein permanentes kontinuierliches Herstellen der thermisch getrennten Profile möglich ist.The present invention has the advantage that the two metal profiles are first formed in the continuous flow method by means of cold forming, these are then brought together, positioned accordingly and then the gap or the gap between the metal profile is then ejected with plastic. In this case, the metal profiles can be positioned so that their edge webs slide on a support surface, the e.g. was prepared with diesel oil or fat-soluble liquid against the adhesion of plastic, so that a permanent continuous production of the thermally separated profiles is possible.

Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Dabei kann beispielsweise vorgesehen sein, dass unter bzw. zwischen die Metallprofile ein Kunststoffband zur Bildung eines Abschlussbodens für den eingespritzten Kunststoff zugeführt wird, wobei dieses Kunststoffband entweder im Inneren des Profiles verbleiben kann oder aber, falls seine Oberfläche entsprechend präpariert ist, nachfolgend kontinuierlich wieder entnommen werden kann.Embodiments of the invention will become apparent from the dependent claims. It can be provided, for example, that under or between the metal profiles, a plastic tape to form a closure bottom for the injected Plastic is supplied, said plastic tape can either remain in the interior of the profile or, if its surface is prepared accordingly, can be subsequently removed again continuously.

Vorteilhaft ist es, wenn bei der Bildung eines doppelten, die Wärmebrücke verhindernden Kunststoffsteges zwischen den Metallprofilen nach Bildung eines ersten Kunststoffsteges ein schwertgeführter Stützkern positioniert wird, der bei kontinuierlichem Vorbeiführen der Metallprofile den Stützboden für den aufgebrachten Kunststoff bildet.It is advantageous if, in the formation of a double, the thermal bridge preventing plastic web between the metal profiles after forming a first plastic web a sword-guided support core is positioned, which forms the support bottom for the applied plastic with continuous passing of the metal profiles.

Auch diese Verfahrensweise hat den Vorteil, dass keinerlei Metallprofilbereiche etwa nach Einspritzen des Kunststoffes entfernt werden müssen.This procedure also has the advantage that no metal profile areas have to be removed, for example, after injection of the plastic.

Je nach Einsatzzweck des jeweiligen Profiles kann es zweckmäßig sein, den Hohlraum zwischen den Metallprofilwänden einerseits und den Kunststoffstegen andererseits ganz auszufüllen, etwa durch Kunststoffschaum. Hierzu sieht die Erfindung vor, dass im Stützkern in Förderrichtung der Metallprofile Perforationen vorgesehen sind, z.B. Bohrungen, zum kontinuierlichen Einbringen von Kunststoffschaum od. dgl. zwischen die gebildeten Kunststoffstege.Depending on the purpose of the particular profile, it may be appropriate to completely fill the cavity between the metal profile walls on the one hand and the plastic webs on the other hand, such as plastic foam. For this purpose, the invention provides that perforations are provided in the support core in the conveying direction of the metal profiles, e.g. Holes for the continuous introduction of plastic foam od. Like. Between the formed plastic webs.

Die Erfindung sieht auch eine entsprechende Anlage vor, die gekennzeichnet ist durch zwei parallele Kaltverformungsstationen zur Bildung je eines mit wenigstens einem Steg mit Rückfalzung versehenen Metallprofiles, eine Zusammenführstation für die beiden entsprechend hergestellten Metallprofile, eine Einspritzstation für den Kunststoff, eine Abkühlstrecke sowie eine Trenneinrichtung zur Abtrennung von gebildeten Profilen in Weiterverarbeitungslängen.The invention also provides a corresponding plant, which is characterized by two parallel cold forming stations for forming a metal profile provided with at least one web with Rückfalzung, a Zusammenführstation for the two correspondingly produced metal profiles, an injection station for the plastic, a cooling section and a separator for Separation of formed profiles in further processing lengths.

Weitere Ausgestaltungen der erfindungsgemäßen Anlage ergeben sich aus den weiteren Anlageansprüchen, die hier zum Inhalt der Beschreibung gemacht werden.Further embodiments of the system according to the invention will become apparent from the other plant claims, which are made here the content of the description.

Die in Fig. 1 schematisch dargestellte, allgemein mit 1 bezeichnete Anlage zur Herstellung von thermisch getrennten Verstärkungsprofilen aus Metall, wie sie querschnittlich in Fig. 11 in unterschiedlichen Varianten dargestellt ist, besteht zunächst aus zwei Kaltverformungs- bzw. Profilierungsstrecken 2 und 3, in denen Metallbänder 4 im Wege der Kaltverformung profiliert werden. Ist dies geschehen, werden sie in einer nicht näher dargestellten Einrichtung 5 zusammengeführt und im kontinuierlichen Durchlauf in einer Kunststoffgießanlage, allgemein mit 6 bezeichnet, mit einer Kunststoffbrücke versehen.In the Fig. 1 schematically illustrated, generally designated 1 plant for the production of thermally separated reinforcing profiles made of metal, as they cross-section in Fig. 11 is shown in different variants, initially consists of two Kaltverformungs- or profiling sections 2 and 3, in which metal strips 4 are profiled by cold deformation. If this is done, they are brought together in a device not shown in detail 5 and provided in a continuous run in a Kunststoffgießanlage, generally designated 6, provided with a plastic bridge.

Nach Durchlaufen einer Kühlstrecke 7, die ebenfalls in Fig. 1 nicht näher dargestellt ist, werden sie in einer Zuschnittanlage 8 auf Länge geschnitten und auf einem Zwischenlager 9 zum weiteren Transport abgelegt. Dieses Zwischenlager 9 kann ebenfalls als Kühlstrecke oder Packanlage (Verpackungsanlage) ausgebildet sein.After passing through a cooling section 7, which is also in Fig. 1 is not shown in detail, they are cut to length in a cutting unit 8 and stored on an intermediate storage 9 for further transport. This intermediate storage 9 can also be designed as a cooling section or packing system (packaging system).

Varianten der Kunststoffgießanlage 6 sind in den Fig. 2 bis 9 wiedergegeben, die nachfolgend etwas näher beschrieben sind:

  • Die unterschiedlichen Varianten der Kunststoffgießanlage 6 sind in den unterschiedlichen Figuren mit 6a, 6b etc. bezeichnet.
Variants of Kunststoffgießanlage 6 are in the Fig. 2 to 9 reproduced below, which are described in more detail below:
  • The different variants of the plastic casting 6 are designated in the different figures with 6a, 6b, etc.

Bezug nehmend auf Fig. 2 wird die Kunststoffgießanlage 6a von auf einer Basis 10 gelagerten Führungs- und Gleitrollen 11 gebildet, die beidseitig die hier im Wesentlichen L-förmig verformten Metallprofile 12 aufnehmen. Zwischen den Rollen 11 ist ein Führungsstab 13 vorgesehen, auf dessen Oberfläche ein Kunststoffband 14 von einem Coil abgewickelt aufgezogen wird, welches das Verkleben des einzuspritzenden Kunststoffes auf den Führungsstab 13 verhindert. Der schnell aushärtende Kunststoff wird über eine Extruderdüse 15 zwischen die Profile 12 gespritzt, er härtet vergleichsweise schnell aus, so dass die Profile 12 im Endlosdurchlauf mit einem entsprechenden, eine Wärmebrücke bildenden Kunststoffsteg 16 nach Durchlauf durch den Bereich 6a versehen sind.Referring to Fig. 2 the plastic casting machine 6a is formed by guide and sliding rollers 11 mounted on a base 10, which receive on both sides the here essentially L-shaped metal profiles 12. Between the rollers 11, a guide rod 13 is provided, on the surface of a plastic belt 14 is wound unwound from a coil, which prevents the bonding of the plastic to be injected on the guide rod 13. The fast-curing plastic is injected via an extruder die 15 between the profiles 12, it cures comparatively quickly, so that the profiles 12 are provided in continuous rotation with a corresponding, forming a thermal bridge plastic web 16 after passing through the area 6a.

In den nachfolgenden Figurenbeschreibungen werden die funktionsmäßig gleichen Elemente mit den gleichen Bezugszeichen versehen, auch wenn sie ggf. konstruktiv geringfügig anders gestaltet sind.In the following description of the figures, the functionally identical elements are provided with the same reference numerals, even if they are structurally slightly differently designed if necessary.

Wie sich aus Fig. 3 ergibt, besteht der Unterschied der Gestaltung der dortigen Kunststoffgießanlage 6b darin, dass statt des Führungsstabes 13 eine Mehrzahl von Führungsrollen 17 vorgesehen ist, auf denen das Kunststoffband 14 aufliegt und so die Unterlage für den zwischen die Metallprofile 12 zu spritzenden Kunststoff bildet.As it turned out Fig. 3 results, the difference in the design of the local Kunststoffgießanlage 6b is that instead of the guide rod 13, a plurality of guide rollers 17 is provided, on which the plastic strip 14 rests and so forms the base for the between the metal profiles 12 to be injected plastic.

In Fig. 4 ist eine abgewandelte Ausführungsform dargestellt. Hier stehen die Metallprofile 12 mit ihren Rückkröpfungen "auf dem Kopf" gegenüber der Position der Ausführungsform nach den Fig. 2 und 3, derart, dass im Profilgrund der thermisch trennende Kunststoffsteg 16 gebildet wird. Hierzu wird das trennende Kunststoffband 14 so auf einem entsprechenden Führungselement 13a geführt, dass ein Anbacken mit dessen Oberfläche nicht erfolgt. Eine solche Konstruktion ist ähnlich der der Fig. 2. Zusätzlich ist in dem Figurenteil B-B in Fig. 4 noch eine Einrichtung 13a als Gleitelement auf der Oberfläche des gebildeten Kunststoffsteges 16 dargestellt, die über eine nicht näher dargestellte Halteeinrichtung 18 in ihrer Position gehalten wird.In Fig. 4 a modified embodiment is shown. Here are the metal profiles 12 with their back turns "upside down" over the position of the embodiment of the Fig. 2 and 3 in such a way that the thermally separating plastic web 16 is formed in the profile base becomes. For this purpose, the separating plastic tape 14 is guided on a corresponding guide element 13a that caking with the surface does not occur. Such a construction is similar to that of Fig. 2 , In addition, in the figure part BB in FIG Fig. 4 nor a device 13a shown as a sliding member on the surface of the formed plastic web 16, which is held by a holding device 18, not shown in position.

In Fig. 5 ist dargestellt, wie zwei doppelt abgekröpfte Metallprofile 12a mit entsprechenden thermisch trennenden Kunststoffstegen ausgerüstet werden. Zunächst wird über eine erste Extruderdüse 15 am Profilgrund, ähnlich wie in Fig. 4 dargestellt, ein erster Kunststoffsteg 16a gebildet, nach Einführen eines entsprechenden Führungsstabes 13a wird dann über eine zweite Extruderdüse 15a der Kunststoffgießanlage 6b der Kunststoff eingebracht zur Bildung des zweiten Kunststoffsteges 16b. Dabei wird über eine Zuführeinrichtung 19 ein Trennmittel auf die Oberfläche des Führungsstabes 13a aufgebracht.In Fig. 5 It is shown how two double-beveled metal profiles 12a are equipped with corresponding thermally separating plastic webs. First, a first extruder nozzle 15 on the profile base, similar to in Fig. 4 shown, a first plastic web 16a formed after insertion of a corresponding guide rod 13a is then introduced via a second extruder die 15a of the Kunststoffgießanlage 6b of plastic to form the second plastic web 16b. In this case, a release agent is applied to the surface of the guide rod 13a via a feed device 19.

In Fig. 6 ist ein Ausführungsbeispiel dargestellt, in dem der Führungsstab 13b nach Erstellen des Kunststoffsteges 16a im Profilgrund unter der Extruderdüse 15 vor der zweiten Extruderdüse 15a eingebracht ist. Dies ist näher und vergrößert auch in Fig. 7 wiedergegeben.In Fig. 6 an embodiment is shown in which the guide rod 13b is introduced after creating the plastic web 16a in the profile base under the extruder die 15 in front of the second extruder die 15a. This is closer and enlarged also in Fig. 7 played.

Dabei ist in Fig. 7 in Verbindung mit Fig. 6 zunächst der untere thermisch trennende Kunststoffsteg 16a räumlich dargestellt zwischen den beiden doppelt abgekröpften Metallprofilen 12a. Der Führungsstab 13 wird dabei von dem entsprechenden Halteelement 13b zwischen den Profilen 12a gehalten.It is in Fig. 7 combined with Fig. 6 first of all the lower thermally separating plastic web 16a shown spatially between the two double-beveled metal profiles 12a. The guide rod 13 is held by the corresponding holding element 13b between the profiles 12a.

Im Unterschied zu Fig. 6 ist in den Fig. 8 und 9 eine weitere Variante dargestellt. Hier kann über den mit inneren Durchgangsbohrungen 20 ausgerüsteten Führungsstab 13c über die Zuführungseinrichtung 19a Kunststoffmaterial eingebracht werden, das dann den Innenraum des Profiles vollständig ausfüllt, wie dies beispielsweise in Fig. 11 bei dem oben rechts dargestellten Profil angedeutet ist.In contrast to Fig. 6 is in the Fig. 8 and 9 another variant shown. Here can be introduced via the equipped with inner through holes 20 guide rod 13c via the feed device 19a plastic material, which then completely fills the interior of the profile, as for example in Fig. 11 is indicated in the profile shown on the top right.

In Fig. 10 ist die Herstellungsweise eines der Metallprofile 12 wiedergegeben, wobei ausgehend von einem Flachband 20 dieses zunächst mit äußeren Zähnen oder Ausbuchtungen 21 od. dgl. versehen wird. Anschließend wird in einem Kaltverformungsschritt eine etwa L-förmige Konfiguration hergestellt mit einer Rückkröpfung 22 auf die Innenfläche des Metallbandes 20. Nach Positionsumkehr wird das Profil z.B. in die Position gemäß Fig. 2 oder 3 gebracht, um dann später mit dem entsprechenden Kunststoffsteg 16 ausgerüstet zu werden. Der Einfachheit halber ist der L-Schenkel des Profiles 12 mit 23 bezeichnet.In Fig. 10 the manufacturing method of one of the metal profiles 12 is reproduced, starting from a flat band 20 of this first od with outer teeth or bulges 21. The like. Is provided. Subsequently, in a cold-forming step, an approximately L-shaped configuration is produced with a back turn 22 on the inner surface of the metal strip 20. After position reversal, the profile is, for example, in the position according to Fig. 2 or 3 brought to be later equipped with the corresponding plastic web 16. For the sake of simplicity, the L-leg of the profile 12 is denoted by 23.
