Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verbinden von Profilen aus thermoplastischem Kunststoff zu Fenster- oder Türrahmen mit einer Anschlagdichtung aus thermoplastischem Kunststoff mittels Heizelementverschweißung. Bei diesem Schweißverfahren ist es üblich, die Anschlagdichtungen erst nach dem Verschweißen der Profile zu den Fenster- oder Türrahmen in eine entsprechende Dichtungsnut einzurollen und, soweit die Anschlagdichtungen aus thermoplastischen Material extrudiert wurden, im Gehrungsbe reich getrennt zu verschweißen. Durch diesen zusätzlichen Ar beitsgang wird die Produktion dieser Fenster- oder Türen jedoch verteuert.The invention relates to a method for connecting profiles made of thermoplastic with window or door frames a stop seal made of thermoplastic material Heating element welding. With this welding process it is usual, the stop seals only after welding the Profiles to the window or door frame in a corresponding Roll the sealing groove and, as far as the stop seals from thermoplastic material were extruded in the miter welded separately. With this additional ar However, the production of these windows or doors becomes a step more expensive.
Es ist daher bereits bekannt, Fenster- bzw. Türrahmenprofile bereits vor dem Verschweißen im Gehrungsbereich mit entspre chenden Anschlagdichtungen zu versehen, wobei diese Anschlag dichtungen im Gehrungsbereich zusammen mit den Profilen in ei nem Arbeitsgang mit verschweißt werden. Profile mit anextru dierten Dichtungen sind beispielsweise aus der EP 0 167 084 B1 sowie der nicht vorveröffentlichten DE 197 20 940 A1 bekannt.It is therefore already known to have window or door frame profiles correspond to the miter area before welding appropriate stop seals, this stop Seals in the miter area together with the profiles in egg welded in one operation. Profiles with anextru dated seals are for example from EP 0 167 084 B1 as well as the unpublished DE 197 20 940 A1.
Durch das Verschweißen der Profile entsteht im Gehrungsbereich eine Schweißwulst mit einer Höhe von einigen Millimetern. Diese wird üblicherweise mit Putzmaschinen im Gehrungsbereich ent fernt. Soweit dieses auch im Bereich der Anschlagdichtungen er folgt, werden diese naturgemäß in diesem Bereich ebenfalls zer stört, wodurch die Dichtungsfunktion im Eckbereich unterbrochen wird. Es ist bereits bekannt, statt der mechanischen Entfernung der Schweißwülste im Dichtungsbereich durch mechanische Kraft einwirkung auf die Anschlagdichtungen im Gehrungsbereich die darunter befindlichen, noch thermoplastisch verformbaren Schweißwülste niederzuquetschen bzw. zu -stauchen. Soweit die Anschlagdichtungen aus thermoplastischem Kunststoff gefertigt sind, werden diese allerdings bei diesem Vorgang bleibend zu sammengequetscht und damit ihrer Dichtungsfunktion beraubt.The profiles are welded in the miter area a sweat with a height of a few millimeters. This is usually done with plastering machines in the miter area distant. As far as he in the area of the stop seals follows, these are naturally also broken up in this area interferes, which interrupts the sealing function in the corner area becomes. It is already known instead of mechanical removal the welding beads in the sealing area due to mechanical force action on the stop seals in the miter area underneath, still thermoplastic Squeeze or sweat welding beads. So far the Stop seals made of thermoplastic are, however, become permanent during this process squeezed together and thus robbed of their sealing function.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren und eine Vorrichtung zum Verschweißen von Fenster- und Türpro filen zur Verfügung zu stellen, das mit geringem Aufwand eine Eckverschweißung von Kunststoffprofilen aus thermoplastischem Kunststoff zusammen mit den Anschlagdichtungen ermöglicht, ohne daß dabei die Dichtungsfunktion im Gehrungsbereich beeinträch tigt wird.The object of the present invention is therefore a method and a device for welding window and door pro filen to provide that with little effort Corner welding of plastic profiles made of thermoplastic Plastic together with the stop seals allows without that this affects the sealing function in the miter area is done.
Die Erfindung löst diese Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie eine Vorrichtung gemäß dem An spruch 2, bevorzugt in Verbindung mit einem oder mehreren der Merkmale des Unteranspruchs.The invention solves this problem by a method with the Features of claim 1 and a device according to the saying 2, preferably in conjunction with one or more of the Features of the subclaim.
Bei dem erfindungsgemäßen Verfahren wird zunächst eine An schlagdichtung aus thermoplastischem Kunststoff mit den zu ver schweißenden Profilen verbunden, beispielsweise durch Einrol len, Eindrücken o. dgl. einer separat extrudierten Anschlag dichtung. Bevorzugt wird jedoch eine anextrudierte Dichtung aus thermoplastischem Material verwendet, insbesondere entsprechend der DE 197 20 940 A1.In the method according to the invention, an An is first Impact seal made of thermoplastic with the ver welded profiles connected, for example by Einrol len, indentation or the like. A separately extruded stop poetry. However, an extruded seal is preferred thermoplastic material used, in particular accordingly DE 197 20 940 A1.
Im nächsten Arbeitsschritt werden die Profile zusammen mit der Anschlagdichtung auf Gehrung geschnitten und zusammen mit der Anschlagdichtung unter Bildung einer Schweißwulst zu den Fen ster- bzw. Türrahmen verschweißt. Die Schweißwulst wird unmit telbar anschließend im noch thermoplastisch verformbaren Zu stand im Gehrungsbereich lediglich in einem Teilbereich der An schlagdichtung durch mechanische Krafteinwirkung auf die An schlagdichtung niedergequetscht bzw. -gestaucht. Zwar kann die Anschlagdichtung bei diesem Vorgang in dem Teilbereich, auf den die mechanische Kraft eingewirkt hat, bleibend verformt werden und damit die Dichtungsfunktion in diesem Bereich vermindert werden, jedoch bleibt die Anschlagdichtung im übrigen Bereich unversehrt. In einem anschließenden Arbeitsgang wird in an sich bekannter Weise, beispielsweise mittels einer üblichen Putzma schine, die Schweißwulst im Gehrungsbereich mechanisch ent fernt, insbesondere durch Fräsen. Dieses Putzen bzw. Fräsen er folgt auch in dem Bereich der Anschlagdichtung, in dem die Schweißwulst noch nicht durch Niederquetschen bzw. -stauchen entfernt wurde. Durch diese mechanische Entfernung wird die Dichtung zwar u. U. im Fußbereich mit entfernt oder zerstört, nicht jedoch im übrigen Bereich, so daß eine ausreichende Dich tungsfunktion gewährleistet bleibt.In the next step, the profiles together with the Miter seal cut and miter together with the Stop seal forming a sweat bead on the fen Welded frame or door frame. The sweat bulge becomes unmit telbar subsequently in the still thermoplastic deformable Zu stood in the miter area only in a partial area of the An Impact seal due to mechanical force on the valve Impact seal crushed or compressed. It can Stop seal during this process in the section on which the mechanical force has acted, are permanently deformed and thus reduces the sealing function in this area , but the stop seal remains in the remaining area intact. In a subsequent step, in itself known manner, for example by means of a conventional cleaning machine machine, the weld bead in the miter area mechanically ent distant, especially by milling. This cleaning or milling he also follows in the area of the stop seal in which the Not yet sweat bulge by crushing or upsetting was removed. This mechanical removal means that Seal and U. removed or destroyed in the foot area, but not in the rest of the area, so that a sufficient you function remains guaranteed.
Bevorzugt wird das erfindungsgemäße Verfahren mittels einer Hand-Hebelpresse ausgeführt. Diese Hebelpresse umfaßt erfin dungsgemäß einen Grundkörper, einen mit dem Grundkörper schwenkbar verbundenen Hebel und einen Stempel zur Stauchung der Schweißwulst. Weiterhin umfaßt die Hebelpresse wenigstens eine Anlagefläche zur Fixierung der Hebelpresse im Gehrungsbe reich des Fenster- oder Türrahmens. Durch diese definierte Fi xierung wird erreicht, daß der Stempel die Anschlagdichtung nur in dem Teilbereich überragt, in dem die Anschlagdichtung nie dergequetscht bzw. -gestaucht werden soll.The method according to the invention is preferred by means of a Hand lever press executed. This lever press includes inventions according to a basic body, one with the basic body pivotally connected lever and a stamp for compression the sweat. Furthermore, the lever press comprises at least a contact surface for fixing the lever press in the miter of the window or door frame. By this defined Fi xierung is achieved that the stamp the stop seal only protrudes in the area where the rebate seal never to be squeezed or compressed.
Nach einer bevorzugten Ausführungsform der Erfindung weist die Hebelpresse zusätzlich einen Anschlag auf, der den Stauchweg auf ein definiertes Maß begrenzt und damit die Schädigung der Dichtung im gestauchten Bereich auf ein notwendiges Maß be schränkt.According to a preferred embodiment of the invention, the Lever press additionally a stop on the upsetting path limited to a defined level and thus damage to the Seal in the compressed area to a necessary degree limits.

In dem in der Zeichnung dargestellten Ausführungsbeispiel wer den an sich bekannte Blendrahmenprofile 12, 12' mit anextrudier ter Anschlagdichtung 13, 13' entsprechend der DE 197 20 940 A1 im Gehrungsbereich 14 durch Heizelementschweißung verbunden. In Fig. 7 ist näher dargestellt, daß die Anschlagdichtung 13, 13' zwei Befestigungsstege 20, 21 sowie eine Dichtlippe 22 aufweist, so daß die Dichtung 13 eine optimale Steifigkeit aufweist und das Fenster absolut dicht schließt. Die Anschlagdichtung 13, 13' verdeckt mit ihren Befestigungsstegen 20, 21 dabei die Dich tungsnut 23, die der Aufnahme einer Ersatzdichtung dient.In the embodiment shown in the drawing who the known frame profiles 12 , 12 'with an extruded ter stop seal 13 , 13 ' according to DE 197 20 940 A1 in the miter area 14 by heating element welding. In Fig. 7 is shown in more detail that the abutment seal 13, 13 'two fixing webs 20, 21 as well as a sealing lip, having 22 so that the seal 13 has an optimum stiffness and the window closes completely sealed. The stop seal 13 , 13 'covered with their fastening webs 20 , 21 , you the groove 23 , which serves to accommodate a replacement seal.
Zum Verschweißen werden die Blendrahmenprofile 12, 12' zunächst zusammen mit den anextrudierten Anschlagdichtungen 13, 13' auf Gehrung geschnitten und in einer handelsüblichen Vierpunkt-Schweißmaschine fixiert. In den Figur ist nicht dargestellt, daß diese Fixierung der Blendrahmenprofile 12, 12' in an sich be kannter Weise durch Spannplatten der Schweißmaschine erfolgt. Diese Spannplatten überragen die in Fig. 6 oben dargestellte spätere Innenseite 15, 15' der Blendrahmenprofile 12, 12' um ei nige Zentimeter und dienen im nächsten Verfahrensschritt als Widerlager für die Oberkante 10 der Hebelpresse 1.For welding, the frame profiles 12 , 12 'are first miter cut together with the extruded stop seals 13 , 13 ' and fixed in a commercially available four-point welding machine. In the figures it is not shown that this fixing of the frame profiles 12 , 12 'takes place in a manner known per se by clamping plates of the welding machine. These clamping plates protrude beyond the later inside 15 , 15 'of the frame profiles 12 , 12 ' shown in FIG. 6 above by a few centimeters and serve in the next process step as an abutment for the upper edge 10 of the lever press 1 .
Die in den Fig. 1 bis 4 dargestellte Hebelpresse 1 besteht im wesentlichen aus dem Grundkörper 2 mit zwei Rippen 3, 3', an dem der Hebel 4 mittels der Achse 5 schwenkbar angeordnet ist. Durch die Schraube 6 mit Feder 7 wird der Hebel 4 im Ruhe zu stand gemäß Fig. 1 gehalten. Unmittelbar nach dem Verschweißen der Blendrahmenprofile 12, 12' wird die Hebelpresse 1 mit den beiden Anschlagflächen 11, 11' im Gehrungsbereich 14 an den vor deren Kanten 16, 16' der Blendrahmenprofile 12, 12' zum Anliegen gebracht. Die Oberkante 10 der Hebelpresse 1 paßt dabei exakt unter die nicht dargestellten Spannplatten der Schweißmaschine, d. h., die Hebelpresse 1 hat insgesamt eine Höhe, die exakt der Tiefe der Blendrahmenprofile 12, 12' entspricht.The lever press 1 shown in FIGS . 1 to 4 consists essentially of the base body 2 with two ribs 3 , 3 ', on which the lever 4 is pivotably arranged by means of the axis 5 . By screw 6 with spring 7 , the lever 4 is held at rest as shown in FIG. 1. Immediately after the frame profiles 12 , 12 'have been welded, the lever press 1 with the two stop surfaces 11 , 11 ' is brought into abutment in the miter region 14 against the edges 16 , 16 'of the frame profiles 12 , 12 '. The upper edge 10 of the lever press 1 fits exactly under the clamping plates, not shown, of the welding machine, ie the lever press 1 has an overall height which corresponds exactly to the depth of the frame profiles 12 , 12 '.
Beim Verschweißen der Blendrahmenprofile 12, 12' werden die an extrudierten Anschlagdichtungen 13, 13' im Gehrungsbereich mit verschweißt. Durch die entstehende Schweißwulst 17 (Fig. 7) wä re jedoch ohne das erfindungsgemäße Niederquetschen der Schweißwulst 17 die Dichtungsfunktion im Gehrungsbereich 14 be einträchtigt. Unmittelbar nach dem Verschweißen der Blendrah menprofile 12, 12' ist die Schweißwulst 17 im Bereich der anex trudierten Anschlagdichtungen 13, 13' noch thermopiastisch ver formbar (Fig. 7). Durch Anheben des Hebels 4 (in Pfeilrichtung F, Fig. 2) wird der vordere Hebelbereich mit dem Stempel 8 in dem Teilbereich 18 (Fig. 7) auf die Schweißwulst 17 gedrückt, wodurch diese in diesem Teilbereich 18 gestaucht bzw. niederge quetscht wird. Diese Quetschung wird bis zu einer definierten Quetschtiefe durchgeführt, wobei der Anschlag 9 den Stauchweg begrenzt.When the window frame profiles 12 , 12 'are welded, the extruded stop seals 13 , 13 ' are also welded in the miter region. Due to the resulting welding bead 17 ( FIG. 7), however, the sealing function in the miter region 14 would be impaired without the welding bead 17 being crushed according to the invention. Immediately after welding the Blendrah menprofile 12 , 12 ', the weld bead 17 is still thermopiastically deformable in the region of the anex truded stop seals 13 , 13 ( Fig. 7). By lifting the lever 4 (in the direction of the arrow F, FIG. 2), the front lever area with the punch 8 in the partial area 18 ( FIG. 7) is pressed onto the welding bead 17 , as a result of which it is compressed or depressed in this partial area 18 . This crushing is carried out to a defined crushing depth, the stop 9 limiting the compression path.
Bei diesem Quetsch- bzw. Stauchvorgang kann es vorkommen, daß die Anschlagdichtung 13, 13' im gequetschten Teilbereich blei bend deformiert wird und einen Teil seiner Dichtfunktion ein büßt (Fig. 8) . Daher wird die Schweißwulst 17 nur im vorderen Bereich 18 der anextrudierten Anschlagdichtung 13, 13' ge staucht, während die Schweißwulst 17 aus dem hinteren Be reich 19 später mechanisch entfernt wird (Fig. 8), beispiels weise mit einer an sich bekannten Putzmaschine. Dabei kann zwar der hintere Befestigungssteg 21 mit zerstört werden, jedoch bleibt die Dichtlippe 22 unversehrt, so daß die Dichtfunktion insgesamt auch im Gehrungsbereich gewährleistet bleibt. In this squeezing or upsetting process, it can happen that the stop seal 13 , 13 'is permanently deformed in the crushed portion and a part of its sealing function is lost ( Fig. 8). Therefore, the weld bead 17 is only in the front region 18 of the anextrudierten stop seal 13, 13 'ge compresses, while the weld 17 from the rear loading rich 19 later is mechanically removed (Fig. 8), example, with a known per se Shine. Although the rear fastening web 21 can also be destroyed, the sealing lip 22 remains intact, so that the sealing function as a whole is also guaranteed in the mitred area.
