Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Rahmen für Fenster oder Türen mit den Maßnahmen des Oberbegriffs des Patentanspruchs 1.The invention relates to a method for producing frames for windows or doors with the measures of the preamble of claim 1.
Rahmen für Fenster oder Türen werden häufig aus PVC (Hart-Polyvinylchlo rid) hergestellt, wobei einzelne abgelängte Kunststoffprofile miteinander ver schweißt werden. Es ist bekannt, die auf Gehrung geschnittenen Kunststoff profile an ihren Stirnseiten mit einem Schweißspiegel so weit zu erwärmen, dass der Kunststoff plastifiziert wird. Anschließend wird der Schweißspiegel entfernt und die plastifizierten Stirnseiten unter Druck zusammengefügt, wobei die Stirnseiten miteinander verschweißen.Frames for windows or doors are often made of PVC (hard polyvinyl chloride rid), whereby individual cut plastic profiles ver be welded. It is known to miter cut plastic heat the profiles on their end faces with a welding mirror so far that the plastic is plasticized. Then the welding mirror removed and the plasticized end faces joined together under pressure, the end faces welded together.
Aus der DE 198 22 292 A1 ist es ferner bekannt, neben dem Gehrungsstoß der Kunststoffprofile Dichtprofile aus Ethylen-Propylen-Dien-Terpolymer (EPDM) anzuordnen. EPDM ist ein Elastomer, das im Unterschied zu Plastomeren unter dem Einfluss von Druck und Temperatur nicht bleibend verformbar ist. Das heißt, ein in das Kunststoffprofil eingezogenes Dichtprofil wird durch das Aufbringen von Wärme durch den Schweißspiegel nicht plastifiziert, sondern behält seinen Aggregatzustand bei. Das bedeutet aller dings auch, dass Dichtprofile im Gehrungsstoß, selbst wenn sie auf Gehrung geschnitten sind, nicht miteinander verschweißt werden können.It is also known from DE 198 22 292 A1, in addition to the miter joint the plastic profiles sealing profiles made of ethylene-propylene-diene terpolymer (EPDM) order. EPDM is an elastomer that is different from Plastomers do not remain under the influence of pressure and temperature is deformable. That means a sealing profile drawn into the plastic profile is not caused by the application of heat by the welding mirror plasticized, but maintains its physical state. That means everyone dings also that sealing profiles in the miter joint, even if they are mitred are cut, cannot be welded together.
Es ist aber bekannt, dass derartige Dichtprofile durch Kleben oder Vulkani sieren miteinander verbunden werden können. Während geklebte Verbin dungen an den Stoßstellen nur einen Teil der Festigkeit des Werkstoffs der Dichtprofile erreichen, ist eine Verbindung durch Vulkanisieren fester, aber fertigungstechnisch aufwendig. Insbesondere müssen die Dichtprofile sepa rat von den Kunststoffprofilen miteinander verbunden werden und nachträg lich in die zu einem Rahmen für Fenster oder Türen zusammengesetzten Kunststoffprofilen eingezogen werden. Der Zeitaufwand hierfür ist relativ groß.But it is known that such sealing profiles by gluing or Vulkani can be connected to each other. While glued verbin only a part of the strength of the material Reaching sealing profiles is a connection by vulcanizing them more firmly, however technically complex. In particular, the sealing profiles must be sepa advice from the plastic profiles are connected together and subsequently Lich in the assembled into a frame for windows or doors Plastic profiles are drawn in. The time required for this is relative large.
Ausgehend von dieser Problematik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Herstellung von Rahmen für Türen oder Fenster aus miteinander verschweißbaren Kunststoffprofilen aufzuzeigen, bei wel chem in die Kunststoffprofile eingezogene Dichtprofile gleichzeitig mit den Kunststoffprofilen miteinander verbunden werden können.Based on this problem, the object of the invention based on a process for the production of frames for doors or windows from weldable plastic profiles to show at wel sealing profiles drawn into the plastic profiles simultaneously with the Plastic profiles can be connected to each other.
Die Erfindung löst diese Aufgabe durch ein Verfahren mit den Maßnahmen des Patentanspruchs 1.The invention solves this problem by a method with the measures of claim 1.
Bei dem erfindungsgemäßen Verfahren werden die Stirnseiten der auf Geh rung geschnittenen Kunststoffprofile in herkömmlicher Weise durch Aufbrin gen von Wärme plastifiziert und unter Druck zusammengefügt. Dies ge schieht in bekannter Weise mit einem Schweißspiegel, der zwischen die Stirnseiten gebracht diese erwärmt, woraufhin die Stirnseiten wieder ausein ander gefahren werden, um den Schweißspiegel zu entfernen. Anschließend werden die Stirnseiten unter Druck zusammengefügt und verschweißen mit einander. Während des gesamten Vorgangs sind neben dem Gehrungsstoß elastomere Dichtprofile gehalten. Die Enden der Dichtprofile werden dabei vor dem Verschweißen der Kunststoffprofile im Bereich des Gehrungsstoßes von jeweils einem Niederhalter fixiert. Jeder Niederhalter ist quasi als Nega tiv des Dichtprofilquerschnitt ausgeführt, so dass die Dichtprofile durch die Niederhalter nicht verformt werden, sondern ihre relative Lage gegenüber den Kunststoffprofilen beibehalten. Die Niederhalter können hierzu auch mehrteilig ausgebildet sein, um kompliziertere Dichtprofilquerschnitte, insbe sondere hinterschnittene Dichtprofile, sicher zu fixieren.In the method according to the invention the end faces of the on tion cut plastic profiles in the conventional way by applying plasticized by heat and assembled under pressure. This ge shoots in a known manner with a welding mirror that is between the End faces brought this warmed up, whereupon the end faces apart again be driven to remove the welding mirror. Subsequently the end faces are joined together under pressure and weld with each other. Throughout the process are next to the miter joint elastomeric sealing profiles held. The ends of the sealing profiles will be there before welding the plastic profiles in the area of the miter joint fixed by a hold-down device. Every hold-down is like a Nega tiv of the sealing profile cross section, so that the sealing profiles through the Hold-down devices are not deformed, but rather their relative position keep the plastic profiles. The hold-down can also do this be formed in several parts, in particular to more complicated sealing profile cross sections special undercut sealing profiles to fix securely.
Die Niederhalter sind ebenso wie die Kunststoffprofile auf Gehrung ge schnitten und behalten ihre relative Lage gegenüber den jeweiligen Kunst stoffprofilen beim Erwärmen der Stirnflächen mit dem Schweißspiegel bei. Das bedeutet, dass die Niederhalter sich zusammen mit den Kunststoffpro filen und den eingezogenen Dichtprofilen auf den Schweißspiegel zu bewe gen und sich gemeinsam wieder von diesem entfernen, wenn der Schweiß spiegel entnommen wird.The hold-down devices, like the plastic profiles, are mitred cut and keep their relative position in relation to the respective art fabric profiles when heating the end faces with the welding mirror. This means that the hold-down clamps together with the plastic pro filen and move the retracted sealing profiles onto the welding mirror gen and together away from this when the sweat mirror is removed.
Nachdem die Stirnseiten der Kunststoffprofile nunmehr aufgeheizt wurden, wird zwischen die Enden der Dichtprofile Kautschuk gegeben. Als Kautschuk in diesem Sinne ist natürlicher oder synthetischer Kautschuk sowie jedes andere zum Vulkanisieren geeignete Material zu verstehen.Now that the end faces of the plastic profiles have been heated up, rubber is placed between the ends of the sealing profiles. As rubber in this sense is natural or synthetic rubber as well as any understand other materials suitable for vulcanization.
Dadurch, dass die Niederhalter auf Gehrung geschnitten sind, wurden diese beim Aufbringen von Wärme durch den Schweißspiegel ebenfalls erwärmt, so dass beim anschließenden Verschweißen der Kunststoffprofile der zwi schen die Enden der Dichtprofile gegebene Kautschuk in den Niederhaltern vulkanisiert wird. Durch die Vulkanisierung haben die Dichtprofile im Geh rungsstoß im wesentlichen die gleichen Dichtungs- und Verformungseigen schaften wie die Dichtprofile an sich. Der vulkanisierte Gehrungsstoß der Dichtprofile hält damit denselben thermischen und mechanischen Belastun gen stand, wie die Dichtprofile in ihrem weiteren Verlauf.Because the hold-downs are mitred, they became also warmed when heat is applied by the welding mirror, so that the subsequent welding of the plastic profiles between rubber ends in the hold-downs is vulcanized. Due to the vulcanization, the sealing profiles have in the go the same sealing and deformation properties like the sealing profiles themselves. The vulcanized miter joint of the Sealing profiles thus hold the same thermal and mechanical stress was the same as the sealing profiles in their further course.
Der besondere Vorteil dieses Verfahrens ist allerdings darin zu sehen, dass die Enden der Dichtprofile gleichzeitig mit dem Verschweißen der Kunst stoffprofile verbunden werden. Durch dieses Verfahren ist eine erhebliche Zeitersparnis und damit Rationalisierung bei der Herstellung von Rahmen für Fenster oder Türen aus miteinander verschweißbaren Kunststoffprofilen möglich.However, the particular advantage of this process can be seen in the fact that the ends of the sealing profiles simultaneously with the welding of the art fabric profiles are connected. This procedure is a significant one Time saving and thus rationalization in the production of frames for Windows or doors made of weldable plastic profiles possible.
Vorteilhaft werden die Fertigungsparameter so gewählt, dass das Vulkanisie ren des Kautschuks und das Verschweißen der Kunststoffprofile zeitgleich abgeschlossen ist (Anspruch 2). Um dieses Ziel zu erreichen, sind eine Reihe von Parametern zu berücksichtigen, wobei neben der Auswahl der Werkstoffe und der Bemessung der eingebrachten Wärmemenge konstruk tive Einflussgrößen eine wesentliche Rolle spielen. Insbesondere kommt es darauf an, wie der Kautschuk zwischen die Enden der Dichtprofile gegeben wird. Während es grundsätzlich möglich ist, eine bestimmte Menge Kautschuk vor dem Zusammenfahren der Kunststoffprofile bzw. der Nieder halter im Bereich des Gehrungsstoßes zu platzieren, wobei sich der Kautschuk gleichmäßig über den Querschnitt des Dichtprofils verteilt, kann auch eine bestimmte Menge Kautschuk jedem Ende der Dichtprofile separat zugeordnet werden. Vorteilhaft kann auch Kautschuk in Form eines Film streifens im Bereich des Gehrungsstoßes platziert werden (Anspruch 3). Der Kautschuk zieht sich nach dem Zusammenfahren der Niederhalter selbsttätig in den Gehrungsstoß ein, wodurch eine gleichmäßige Verbindung der Enden der Dichtprofile durch Vulkanisierung entsteht.The manufacturing parameters are advantageously chosen so that the vulcanization rubber and welding of the plastic profiles at the same time is completed (claim 2). To achieve this goal are one Set of parameters to take into account, in addition to selecting the Materials and the dimensioning of the introduced heat quantity influencing factors play an important role. In particular it happens on how the rubber is given between the ends of the sealing profiles becomes. While it is basically possible, a certain amount Rubber before moving the plastic profiles or the Nieder to place the holder in the area of the miter joint, whereby the Rubber can be evenly distributed over the cross-section of the sealing profile also a certain amount of rubber separately at each end of the sealing profiles be assigned. Rubber in the form of a film can also be advantageous strips are placed in the area of the miter joint (claim 3). The Rubber pulls itself automatically after the hold-down devices move together into the miter joint, creating an even connection of the ends the sealing profiles are created by vulcanization.
Nach den Maßnahmen des Anspruchs 4 wird der Kautschuk zwischen die Enden der Dichtprofile injiziert. Hierzu ist wenigstens ein Niederhalter mit einer Zuführung für den Kautschuk versehen.According to the measures of claim 4, the rubber is between the Ends of the sealing profiles injected. For this purpose, at least one hold-down device is included a feeder for the rubber.
In Abhängigkeit von der Zuführung des Kautschuks bzw. von der ge wünschten Konturierung im Bereich des Gehrungsstoßes besitzen die Nie derhalter angepasste Querschnitte. Es ist daher möglich, dass die durch Vulkanisierung miteinander verbundenen Enden der Dichtprofile im Geh rungsstoß eine von ihrem Profilquerschnitt abweichende Kontur haben (An spruch 5). Dies kann gewünscht sein, um das Verformungsverhalten der flussen oder auch um den Vulkanisiervorgang verfahrenstechnisch zu er leichtern. Natürlich ist es auch möglich, dass der Profilquerschnitt der Dicht profile im Gehrungsstoß beibehalten wird (Anspruch 6).Depending on the supply of the rubber or on the ge the never have the desired contouring in the area of the miter joint adapted cross sections. It is therefore possible that through Vulcanization of interconnected ends of the sealing profiles in the walk butt joint have a contour that deviates from their profile cross-section (An Proverb 5). This may be desirable to determine the deformation behavior of the flow or to process the vulcanization process easier. Of course, it is also possible that the profile cross section of the seal profile is maintained in the miter joint (claim 6).
Das erfindungsgemäße Verfahren eignet sich besonders zur Verbindung von Dichtprofilen, die aus einem Ethylen-Propylen-Kautschuk hergestellt sind (Anspruch 7).The method according to the invention is particularly suitable for connecting Sealing profiles made of an ethylene-propylene rubber (Claim 7).
Die Menge des zuzuführenden und damit zu vulkanisierenden Kautschuks wird durch die Ablängung der Enden der Dichtprofile gesteuert. Je weiter die Enden der Dichtprofile vom Gehrungsstoß entfernt sind, desto größer ist die Menge des zu vulkanisierenden Kautschuks. Dementsprechend ist die Menge des erforderlichen Kautschuk gering, wenn die Enden der Dichtprofile im Bereich des Gehrungsstoßes liegen und ebenfalls auf Gehrung geschnitten sind. Die Verbindung der Enden der Dichtprofile ist dann auf den unmittelbaren Bereich des Gehrungsstoßes beschränkt.The amount of rubber to be fed and thus vulcanized is controlled by cutting the ends of the sealing profiles. The further the The ends of the sealing profiles are removed from the miter joint, the larger the Amount of rubber to be vulcanized. Accordingly, the Amount of rubber required is low when the ends of the sealing profiles are in the area of the miter joint and are also mitred are cut. The connection of the ends of the sealing profiles is then on the limited immediate area of the miter joint.
Das erfindungsgemäße Verfahren wird anhand der in den Zeichnungen dar gestellten Ausführungsbeispiele nachfolgend näher erläutert. Es zeigen:The method according to the invention is illustrated in the drawings presented embodiments explained in more detail below. Show it:

Die Enden 9 sind vom Gehrungsstoß 8 beabstandet. Sie werden jeweils von Nieder haltern 10 gegen die Schenkel 5 der Kunststoffprofile 1, 2 gedrückt. Hierzu werden die Niederhalter 10 in Richtung der Pfeile PF entlang der strichpunk tierten Linien L in der Bildebene nach unten bewegt, wobei die Niederhalter 10 die Enden 9 der Dichtprofile 7 übergreifen. Die Niederhalter 10 sind ebenfalls auf 45° Gehrung geschnitten, wobei ihre Stirnflächen 11 mit den Stirnseiten 3, 4 der Kunststoffprofile 1, 2 in einer Ebene liegen (Fig. 2). Die Niederhalter 10 sind in ihrem Querschnitt gegengleich zu dem Querschnitt der Dichtprofile 7 ausgebildet, so dass zwischen den Enden 9 der Dichtpro file 7 und den Stirnseiten 3, 4 der Kunststoffprofile 1, 2 bei auf den Schen keln 5 aufgesetzten Niederhaltern 10 ein Hohlraum entsteht, der dem Quer schnitt der Dichtprofile 7 oberhalb der Aufnahmenut 6 entspricht. A miter joint 8 between the end faces 3 , 4 of the plastic profiles 1 , 2 facing ends 9 of the sealing profiles 7 do not extend in this embodiment, for example, to the end faces 3 , 4 of the plastic profiles 1 , 2 . The ends 9 are spaced from the miter joint 8 . They are each pressed down by 10 holders against the legs 5 of the plastic profiles 1 , 2 . For this purpose, the hold-down devices 10 are moved downward in the direction of the arrows PF along the dash-dotted lines L in the image plane, the hold-down devices 10 overlapping the ends 9 of the sealing profiles 7 . The hold-down devices 10 are also cut at a 45 ° miter, their end faces 11 lying with the end faces 3 , 4 of the plastic profiles 1 , 2 in one plane ( FIG. 2). The hold-downs 10 are formed in their cross-section diametrically opposed to the cross section of the sealing profiles 7, so that between the ends 9 of the Dichtpro file 7 and the end faces 3, 4 of the plastic profiles 1, 2 in on the legs angles 5 mounted holding-down devices 10 a cavity is formed, which corresponds to the cross section of the sealing profiles 7 above the receiving groove 6 .
Nach dem Aufsetzen der Niederhalter 10 auf die Schenkel 5 wird ein Schweißspiegel 12 in Richtung des Pfeils PF1 in den Gehrungsstoß 8 ein geführt. Die Kunststoffprofile 1, 2 werden dann zusammen mit den Dichtpro filen 7 und den Niederhaltern 10 in Richtung der Pfeile PF2 auf den Geh rungsstoß 8 bzw. den Schweißspiegel 12 zu bewegt und dort zur Anlage gebracht; vgl. Fig. 3. Durch den Schweißspiegel 12 werden die Stirnseiten 3, 4 der Kunststoffprofile 1, 2 plastifiziert und die Niederhalter 10 erwärmt. Anschließend werden die Kunststoffprofile 1, 2 mit den Niederhaltern 10 und den Dichtprofilen 7 wieder auseinander gefahren und der Schweißspiegel 12 entfernt.After placing the hold-down device 10 on the legs 5 , a welding mirror 12 is guided in the direction of arrow PF1 into the miter joint 8 . The plastic profiles 1 , 2 are then together with the Dichtpro filen 7 and the hold-down device 10 in the direction of the arrows PF2 on the walking joint 8 or the welding mirror 12 to be moved and brought to rest there; see. Fig. 3. The welding mirror 12, the end faces 3, 4 of the plastic profiles 1, 2 are plasticized and heats the down device 10. The plastic profiles 1 , 2 with the hold-down devices 10 and the sealing profiles 7 are then moved apart again and the welding mirror 12 is removed.
Fig. 4a zeigt nun eine erste Ausführungsform, bei der Kautschuk 13 in Form eines Filmstreifens in Richtung des Pfeils PF3 zwischen die Enden 9 der Dichtprofile 7 bzw. die Stirnflächen 11 der Niederhalter 10 gebracht wird. Anschließend werden die Kunststoffprofile 1, 2 zusammen mit den Nieder haltern 10 und den Dichtprofilen 7 in Richtung der Pfeile PF4 aufeinander zu bewegt. Im Gehrungsstoß 8 verschweißen dann die plastifizierten Stirnseiten 3, 4 der Kunststoffprofile 1, 2 miteinander, während der Kautschuk 13 im Niederhalter 10 vulkanisiert wird und die Enden der Dichtprofile 7 miteinan der verbindet. FIG. 4a now shows a first embodiment wherein the rubber 13 in the form of a film strip in the direction of arrow PF3 between the ends 9 of the sealing profiles 7 and the end surfaces 11 of the holding-down device 10 is placed. Then the plastic profiles 1 , 2 are moved together with the hold-down devices 10 and the sealing profiles 7 in the direction of the arrows PF4. In the miter joint 8 then the plasticized end faces 3 , 4 of the plastic profiles 1 , 2 weld to one another, while the rubber 13 is vulcanized in the hold-down device 10 and the ends of the sealing profiles 7 are joined together.
Eine weitere Variante für die Zuführung des Kautschuks zeigt Fig. 4b, wobei eine kugelförmige Menge Kautschuk 13 zwischen die Stirnflächen 11 der Niederhalter 10 in Richtung des Pfeils PF3 gebracht wird.A further variant for the feed of the rubber, Fig. 4b, where a spherical amount of rubber 13 is put between the end faces 11 of the holding-down device 10 in the direction of arrow PF3.
In der Ausführungsform nach Fig. 4c wird der Kautschuk 13 über eine Lanze 14 in den nicht näher dargestellten Hohlraum zwischen den Enden 9 der Dichtprofile 7 innerhalb der Niederhalter 10 injiziert. Die Lanze 14 befindet sich hierbei in der Ebene des Gehrungsstoßes 8 und greift zwischen die Stirnflächen 11 der Niederhalter 10, um den Kautschuk 13 zentral zu injizieren. In the embodiment according to FIG. 4c, the rubber 13 is injected via a lance 14 into the cavity, not shown, between the ends 9 of the sealing profiles 7 within the hold-down device 10 . The lance 14 is located in the plane of the miter joint 8 and engages between the end faces 11 of the hold-down device 10 in order to inject the rubber 13 centrally.
Fig. 5 zeigt schließlich die zu einer Ecke miteinander verbundenen Kunst stoffprofile 1, 2 sowie die durch Vulkanisieren verbundenen Enden 9 der Dichtprofile 7 nach dem Entfernen der Niederhalter 10. Die Dichtprofile 7 besitzen hierbei einen durchgehenden gleichbleibenden Querschnitt, der sich über die Enden 9 hinaus bis in den Gehrungsstoß 8 erstreckt. Dadurch wird sichergestellt, dass die Dichtprofile auch im Verbindungsbereich ein gleichbleibendes Verformungsverhalten besitzen. Fig. 5 shows, finally, the interconnected to a corner of the plastic profile 1, 2 and connected by vulcanizing ends 9 of the sealing profiles 7 after removal of the down device 10. The sealing profiles 7 in this case have a continuous, constant cross-section which extends beyond the ends 9 into the miter joint 8 . This ensures that the sealing profiles also have a constant deformation behavior in the connection area.
