Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Profilleisten o. dgl. mit geschlossenen Endbereichen gemäß dem Oberbegriff des Patentanspruches 1 und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing profile strips or the like. With closed end regions according to the Preamble of claim 1 and a device to carry out the procedure.

Bekannt ist beispielsweise ein Verfahren, bei welchem ein auf einer Walzenstraße gefertigtes Edelstahl- oder Alu-Profil mit einem Haftvermittler beschichtet und in einem Extruder­ kopf mit Kunststoff umspritzt und verklebt wird. Bei dieser Verfahrensweise können jedoch nur Profilleisten gefertigt werden, welche über die gesamte Länge denselben Querschnitt aufweisen. Diese im Endlosstrangverfahren erstellten Profil­ leisten werden anschließend in einem relativ aufwendigen Verfahren mit angespritzten Kunststoffendstücken versehen.For example, a method is known in which a Stainless steel or aluminum profile made on a roller mill coated with an adhesion promoter and in an extruder the head is overmolded with plastic and glued. At this In practice, however, only profile strips can be manufactured which have the same cross-section over the entire length exhibit. This profile created in the endless strand process are then afforded in a relatively elaborate Provide the process with molded plastic end pieces.

Des weiteren sind Verfahren zur Herstellung von Profilleisten o. dgl. bekannt, bei denen ein Edelstahl- oder Alu-Profil mit Haftvermittler versehen und mit einem Kunststoffspritzteil durch induktive Erwärmung verklebt wird. Diese Verfahrensart ermöglicht es zwar, eine über die gesamte Länge verschieden­ artige Profilquerschnittgestaltung mit den jeweils konstruk­ tiv gewünschten Endformen zu erhalten, ist jedoch durch eine zusätzlich notwendig werdende MF-Induktionsklebemaschine und die zusätzlich anfallenden Handzeiten, wie Einknüpfen und Beschneiden eines eventuell gewünschten Blankbereichs für eine kostengünstige Fertigung relativ aufwendig.Furthermore, there are processes for the production of profile strips o. Like. Known in which a stainless steel or aluminum profile provided with adhesion promoter and with a plastic injection molded part is glued by inductive heating. This type of procedure allows one to be different over the entire length like profile cross-section design with each construct tiv to obtain the desired final forms is, however, by a MF induction gluing machine and the additional hand times, such as knotting and  Crop any blank area you want for cost-effective production is relatively complex.

Bedingt durch Toleranzen in Edelstahl- oder Alu-Profilblech sowie bei gespritzten Kunststoffprofilen liegen zu verklebende Flächen auch bei Aufbringen von Anpreßdruck nicht immer überall aneinander an, so daß eine durchgehende gleichmäßige Klebeverbindung nicht immer erreichbar ist.Due to tolerances in stainless steel or aluminum profile sheet as well as with molded plastic profiles to be glued Surfaces not always everywhere, even when pressure is applied to each other so that a continuous even Adhesive connection is not always accessible.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrich­ tung zur Herstellung von Profilleisten aufzuzeigen, mit welchem Profilleisten mit einem Kern aus Edelstahl, Alumini­ um oder auch Hart-PVC, mit einer PVC-Ummantelung mittels einer einwandfreien Klebeverbindung herstellbar sind, wobei gleich­ zeitig die Profilleisten mit praktisch beliebigem Quer­ schnitt herstellbar sein sollen und die Herstellung mög­ lichst kostengünstig sein soll.The object of the invention is a method and a Vorrich to demonstrate the production of profile strips with which profile strips with a core made of stainless steel, aluminum um or also hard PVC, with a PVC sheathing by means of a flawless adhesive connection can be produced, being the same timely the profile strips with practically any cross cut should be producible and the production possible should be as inexpensive as possible.

Diese Aufgabe ist durch ein Verfahren gemäß dem Patentan­ spruch 1 beziehungsweise eine Vorrichtung gemäß dem Patentan­ spruch 6 gelöst.This object is achieved by a method according to the patent award 1 or a device according to the patent saying 6 solved.

Bei einer Profilleiste, die aus Hart-PVC gefertigt ist, liegt sowohl die Vorerwärmungstemperatur als auch die Akti­ vierungstemperatur des Haftvermittlers niedriger, als bei einer Profilleiste, welche aus Edelstahl oder Alu gefertigt ist. Bei letzteren liegt die Vorerwärmungstemperatur bei etwa 120 bis 150 Grad Celsius, bei einer Profilleiste aus Hart-PVC bei ca. 60 bis 70 Grad Celsius.For a profile strip that is made of hard PVC, lies both the preheating temperature and the acti bonding temperature lower than at a profile strip, which is made of stainless steel or aluminum is. The preheating temperature is included in the latter  about 120 to 150 degrees Celsius, with a profile strip Hard PVC at approx. 60 to 70 degrees Celsius.

Die so vorbehandelte Metall- oder Hart-PVC-Profilleiste wird in eine beheizte Spritzgießform so eingelegt, daß sie bei­ spielsweise mittels eines Elektro- oder Permanent-Magneten oder anderweitig in der Form ihre vorgesehene Auf- und Anlage erhält. Nach dem Schließen der Spritzgießform wird die je­ weils einliegende und vorbehandelte Metall- oder Hart-PVC- Profilleiste mit vorzugsweise Weich-PVC o. dgl. bei einer Spritztemperatur von ca. 170 Grad Celsius ummantelt. Beim Auftreffen der heißen Kunststoffspritzmasse auf die jeweili­ ge vorbehandelte Metall- oder Hart-PVC-Profilleistenober­ fläche wird der Haftvermittler aktiviert.The metal or hard PVC profile strip pretreated in this way becomes placed in a heated injection mold so that it at for example by means of an electric or permanent magnet or otherwise in the form of their intended installation and layout receives. After closing the injection mold the because of the inserted and pre-treated metal or hard PVC Profile strip with preferably soft PVC or the like at one Coated spray temperature of approx. 170 degrees Celsius. At the Impact of the hot plastic injection compound on the respective pretreated metal or hard PVC profile strips the adhesive agent is activated.

Die Aktivierungstemperatur sollte so gewählt werden, daß sie immer unter der Schmelztemperatur (ca. 170 bis 180 Grad Celsius) des jeweils eingespritzten Kunststoffes liegt.The activation temperature should be chosen so that it always below the melting temperature (approx. 170 to 180 degrees Celsius) of the injected plastic.

Versuche haben ergeben, daß Haftvermittler mit verschiedenen Aktivierungstemperaturen nach dem Auftragen auf eine Metall- oder Hart-PVC-Profilleiste und vor dem Ummanteln auf ca. 70% bis 80% ihrer ange­ gebenen Aktivierungstemperatur aufgeheizt sein müssen, um durch den Wärmeübergang vom Spritzmedium die geforderte Aktivierungstemperatur zu erreichen. Experiments have shown that adhesion promoters with different Activation temperatures after application to a metal or hard PVC profile strip and before sheathing on approx. 70% to 80% of their ange given activation temperature must be heated to due to the heat transfer from the spray medium the required To reach activation temperature.  

Bei schwierigen Teilen oder Profilen mit eingelegter Hart- PVC-Profilleiste wurde beispielsweise auf eine Wärmevor­ behandlung verzichtet und nach dem Ummanteln der Profillei­ sten der jeweilige Haftvermittler durch bloßes Auflegen auf eine beheizte Profilschiene oder auch durch induktive Erwär­ mung aktiviert.For difficult parts or profiles with inserted hard PVC profile strip was pre-heated, for example treatment waived and after coating the Profillei the respective adhesion promoter by simply hanging up a heated profile rail or by induction heating activated.

Ein zusätzlicher Anpreßdruck war hier nicht erforderlich, weil durch den hohen Einspritzdruck das Spritzmedium gleich­ mäßig an jedem Punkt der einliegenden Profilleiste fest anlag und somit der Haftvermittler beide Teile fest verbin­ den konnte.An additional contact pressure was not necessary here because the spray medium is the same due to the high injection pressure moderately firm at every point of the inserted profile strip system and thus the adhesion promoter firmly connected both parts could.

Mittels der angeführten Lösungsmöglichkeit können auch bei langen Profilleisten Sichtbereiche, Fenster o. dgl. mit in die vorgesehene Kunststoffprofilform eingespritzt werden, ohne nachträglich eine Beschneidung vorzunehmen.By means of the listed solution, you can also at long profile strips visible areas, windows or the like with in the intended plastic profile shape is injected, without subsequently circumcising.

Nachstehend wird die Erfindung noch an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles beschrieben, in welcher zeigtIn the following, the invention will be described with reference to Drawing shown embodiment described in which shows

Fig. 4 einen Querschnitt durch eine in Kunststoff eingebettete Flachinduktor-Spule mit aufgeleg­ ter Profilleiste. Fig. 4 shows a cross section through an embedded plastic inductor coil with superimposed profile strip.

Die in Fig. 1 dargestellte Spritzgießform dient zum Verbin­ den von Edelstahl-, Alu- oder Hart-PVC-Profilleisten mit Kunststoff, vorzugsweise Weich-PVC (Polyvinylchlorid).The injection mold shown in Fig. 1 is used to connect the stainless steel, aluminum or hard PVC profile strips with plastic, preferably soft PVC (polyvinyl chloride).

Vor dem Einspritzen der Kunststoffmasse 1 wird die Edel­ stahl-Profilleiste 2 in die Aufnahmeun­ terform 3 eingelegt und darin mittels Permanent- oder Elek­ tro-Magnet 4 so gehalten, daß eine gleichmäßige Auflage an allene Flächen und Punkten gewährleistet ist.Prior to the injection of the plastic mass 1, the precious steel profile bar 2 is inserted into the Aufnahmeun terform 3 and is so held by means of permanent or elec tro-magnet 4 that uniform support is ensured at allene areas and dots.

Bei eventuellen Freiflächen oder sogenannten Sichtbereichen 2′ (Fig. 1) ist vorgesehen, je nach Breite und Länge des Sichtbereiches vor dem Umspritzen eine Klebefolie aufzutra­ gen, um eine Oberflächenverkratzung oder -beschädigung durch den Kernzug zu vermeiden. In the case of possible open spaces or so-called viewing areas 2 ' ( Fig. 1), depending on the width and length of the viewing area, it is intended to apply an adhesive film before overmolding in order to avoid surface scratching or damage to the core pull.

In den Fig. 3 und 4 sind Profilleisten gezeigt, die nach der Kunststoffummantelung durch Auflegen auf einen Profilträger erwärmt und verklebt werden. Der profilierte Aufnahmeträger 5 in Fig. 3, vorzugsweise aus Kupfer gefer­ tigt, wird mittels Elektro-Heizelementen 6 aufgeheizt.In FIGS. 3 and 4 profile strips are shown, the heated and after the plastic covering by laying it on a profile carrier are glued. The profiled seat support 5 in Fig. 3, preferably of copper gefer Untitled is heated by electric heating elements. 6

Um eine einwandfreie schlüssige Auflage der Edelstahl- Profilleiste 2 auf dem Aufnahmeträger 5 zu erreichen (Fig. 3), erscheint es zweckmäßig, einen Permanent- oder Elektro-Magneten 4 vorzusehen.In order to achieve a perfect, coherent support of the stainless steel profile strip 2 on the receiving support 5 ( FIG. 3), it appears expedient to provide a permanent or electric magnet 4 .

Eine andere Art der Aufheizung der Edelstahl- oder Alu- Profilleisten ist in Fig. 4 dargestellt. Mittels einer Flach­ induktionsspule 7 wird Wärme zum Aktivieren des Haftvermitt­ lers erzeugt. Die MF-Flachinduktionsspule ist in eine Kunst­ stoffaufnahmeform 8 eingebettet, wobei das jeweilige Aufnah­ meprofil für eine Profilleiste in die Kunststoffaufnahmeform eingearbeitet ist. Auch hier wird die aufliegende Edelstahl- oder Alu-Profilleiste 2 mit dem umspritzten Kunststoffprofil 9 ohne zusätzlichen Anpreßdruck verklebt.Another type of heating the stainless steel or aluminum profile strips is shown in Fig. 4. By means of a flat induction coil 7 , heat is generated to activate the adhesion promoter. The MF flat induction coil is embedded in a plastic receiving mold 8 , the respective receiving profile being incorporated into the plastic receiving mold for a profile strip. Again, the overlying stainless steel or aluminum profile bar 2 is bonded to the molded plastic profile 9 without additional contact pressure.
