Description
Die vorliegende Erfindung bezieht sich auf das Ver- The present invention relates to the
schweißen hohler Kunststoffprofile insbesondere zur Bildung von rahmenEhnlichen Anordnungen, sowie auf KunststofRprofile und dafür zu verwendende Einsätze.welding of hollow plastic profiles, especially to form frame-like ones Arrangements, as well as on plastic profiles and inserts to be used for them.
Zur Zeit werden Kunststoffprofile durch bekannte Verfahren miteinander verschweißt, bei denen man z.B. eine dUnne , auf eine Temperatur von 190 - 2500C elektrisch beheizte Metallplatte zwischen die beiden miteinander zu verschweißenden Stoßenden legt. Reicht die Heizwirkung aus, um das thermoplastische Material zu erweichen, so wird die dünne Platte entfernt, und die beiden Profile werden zusammengepreßt, so daß sie miteinander verschweißt werden. Im Bereich der Schweißnaht kann es aber zu einem Abbau des Kunststoffs kommen, so daß seine Festigkeit darunter leidet. Aus diesem Grunde besitzt die Verschweißung eine schwache Stelle bzw. Linie, an der sie leicht auseinandergerissen und zerstört werden kann. Dies trifft insbesondere dann zu, wenn sich die Verschweißung an der Ecke eines aus Profilen hergestellten Rahmens befindet. At present, plastic profiles are interconnected by known methods welded, in which, for example, a thin, at a temperature of 190 - 2500C electrically heated metal plate between the two to be welded together Butt ends. Is the heating effect sufficient to control the thermoplastic material soften, the thin plate is removed and the two profiles are pressed together, so that they are welded together. However, it can be in the area of the weld seam cause the plastic to degrade so that its strength suffers. For this reason, the weld has a weak point or line which it can easily be torn apart and destroyed. This is particularly true then to when the weld is at the corner of one made of profiles Frame is located.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und ein Verstrkungselement im Bereich der Verschweißung anzuordnen. The present invention is based on these disadvantages to remove and to arrange a reinforcement element in the area of the weld.
Zur Lösung dieser Aufgabe ist das erfindungsgemaße Verfahren zum Zusammenschweißen hohler thermoplastischer Profile dadurch gekennzeichnet, daß man einen thermoplastischen, an einem Ende mehrere zur Seite hinausragende Laschen besitzenden Einsatz in ein offenes Ende eines der Profile einführt, so daß die Laschen gegen den Rand des offenen Endes zu liegen kommen, und daß man die offenen Enden und die diesen zugeordneten thermoplastischen Einsätze miteinander durch eine Stoßverschweißung verbindet, so daA die Laschen und die Profile miteinander vereinigt bzw. verschmolzen werden. To solve this problem, the inventive method is for Welding together hollow thermoplastic profiles, characterized in that one a thermoplastic having several tabs protruding to the side at one end Insert insert into an open end of one of the profiles so that the tabs against the edge of the open end come to rest, and that one the open ends and the these associated thermoplastic inserts to one another by butt welding connects, so that the tabs and the profiles are united or fused with one another will.
Zur Herstellung rechtwinkliger Ecken können das offene Ende jeden Profils und das genannte eine Ende des Einsatzes vor dem Vehweißen unter einem Winkel von 450 zur Prof illängsachse stehen. Any open end can be used to make square corners Profile and said one end of the insert prior to being welded at an angle from 450 to the longitudinal axis of the profile.
Gemäß einem weiteren Merkmal bezieht sich die Errindung auf die Kombination eines hohlen, thermoplastischen Profils und eines bei dem erfindungsgemäßen Verfahren anzuwendenden Einsatzes, der aus thermoplastischem Werkstoff besteht und an einem Ende mehrere zur Seite hinausragende Laschen besitzt, so daß die Laschen, wenn der Einsatz in ein offenes Ende des Profils eingeführt wird, auf den Rand des offenen Endes zu liegen kommen. According to a further feature, the invention relates to the combination a hollow, thermoplastic profile and one in the method according to the invention applicable insert, which consists of thermoplastic material and on a End has several tabs protruding to the side, so that the tabs when the Insert is inserted into an open end of the profile, onto the edge of the open End up coming to a standstill.
Um den Einsatz sicherer in das hohle Profil einführen zu können, kann das Profil mit Längarippan versehen sein, die in Nuten der SiNsEtze eingreifen können. In order to be able to introduce the insert more safely into the hollow profile, the profile can be provided with lengthways ribs that engage in the grooves of the SiNsEtze can.
Die Erfindung bezieht sich weiterhin auf einen Einsatz zur Verwendung bei einer solchen Kombination, der aus thermoplastischem Material besteht und einends mehrere, zur Seite hinausragende Laschen besitzt. Vorzugsweise stehen die Laschen von dem einen Ende in bezug auf die Längsrichtung des Einsatzes hervor, so daß es bei dem Verschweißen nur darauf ankommt, daß die taschen miteinander und mit den offenen Enden der Profile verschmolzen bzw. verschweißt werden. Auf diese Weise wird eiz thermische Verformung an den offenen Enden der Profile vermieden und eine reste Verbindung gewhrleistet. The invention further relates to an insert for use in such a combination, which consists of thermoplastic material and at one end has several tabs protruding to the side. Preferably the tabs are upright from one end with respect to the longitudinal direction of the insert so that it When welding, the only thing that matters is that the pockets with each other and with the open ends of the profiles are fused or welded. In this way eiz thermal deformation at the open ends of the profiles is avoided and a remaining connection guaranteed.
Weitbre Einzelheiten, Vorteile und Merkmale sind der nun folgenden Beschreibung einer nur beispielshaften Ausführungsform dr Erfindung zu entnehmen. Broad details, advantages, and features are as follows Description of an exemplary embodiment of the invention can be found.
fig. 1 zeigt in perspektivischer Darstellung ein hohles Profil sowie einen Einsatz, deren Enden unter einem Winkel von 450 zueinander liegen, um eine Eckverbindung herzustellen; Fig. 2 zeigt einen schematischen Längsschnitt der Anordnung tor dem Zusammenschweißen der beiden thermoplastischen Profile; Zig. 3 zeigt einen Schnitt entsprechend der Fig. 2 nach dem Verschwei ßen; und Zig. 4 zeigt eine schematische perspektivische Darstellung der verschwelßten Eckverbindung gemEB Fig. 3. fig. 1 shows a perspective view of a hollow profile as well an insert, the ends of which are at an angle of 450 to each other, around a Establish corner connection; Fig. 2 shows a schematic longitudinal section of the arrangement tor the welding together of the two thermoplastic profiles; Zig. 3 shows one Section corresponding to FIG. 2 after the welding Shen; and Zig. 4 shows a schematic perspective illustration of the welded corner connection according to FIG. 3.
Fig. 1 zeigt das offene Ende eines hohlen, aus thermoplastischem Material bestehenden Profils 1 mit einem Innenraum 2 und einer Schnittkante 5, die unter einem Winkel von 45° zur Längsachse des Profils liegt. Der ebenfails aun thermoplastischem Material bestchende Einsatz 3 kann mit einer genauen Passung in den Hohiraum 2 des Profils 1 eingeführt werden. Der Einsat@ 3 hat Längsnuten 10 zur Aufnahme von an der InnenflJche des Profils 1 vorgesehenen Rippen 11. Der Einsatz 3 besitzt weiterhin seitlich hinausragende taschen b, 7, 8 und 9, die Uber den est des Einsat/es 5 nach den Selten vorstehen und auf dle Kante 5 des Proflis 1 zu liegen kommen, wenn der Einsatz in das offene Ende des Profils 1 eingefünrt ist. Diese Läschen verhindern, daß der Einsat@ zu weit in den Hohiraum des Profils 1 eingesteckt wird. Welterhin ragen die taschen vom Einsatz 3 in der Längsrichtung hervor, um ein Punktschweißen zu erleichtern. Fig. 1 shows the open end of a hollow, thermoplastic Material existing profile 1 with an interior 2 and a cut edge 5, which at an angle 45 ° to the longitudinal axis of the profile. Of the Insert 3, which is also made of thermoplastic material, can be provided with an accurate Fit in the cavity 2 of the profile 1 are introduced. The Einsat @ 3 has longitudinal grooves 10 for receiving ribs 11 provided on the inner surface of the profile 1 Insert 3 also has laterally protruding pockets b, 7, 8 and 9, the Uber the est des Einsat / es 5 protrude after the rare and on the edge 5 of the professional 1 come to rest when the insert goes into the open end of the profile 1 is. These small holes prevent the insert @ too far into the hollow space of the profile 1 is plugged in. Worldwide, the pockets protrude from the insert 3 in the longitudinal direction to facilitate spot welding.
Wie aus den Fig. 2 bis 4 ersichtlich ist, wird zwecks Verbindung der beiden Profile ein Einsatz D in das offene Ende eines jeden Profils 1 eingeschoben, und dio Profile werden remtä rig. 2 aufeinander zu bewegt. As can be seen from FIGS. 2 to 4, for the purpose of connection of the two profiles, an insert D is inserted into the open end of each profile 1, and the profiles become permanent. 2 moved towards each other.
Es erfoigt dann das Verschweißen unter Anwendung eines bekannten Schweißverfahrens derart1 das nicht nur die anstoßenden Laschen 6, 7, 8 und 9, sondern auch die Flächen der Kanten 5, mit den die Laschen in Kontakt kommen, miteinander verschweißt bzw. verschmolzen werden. Anhand der in Fig. und 4 abgebildeten, fertigen Eckschweißverbindung sieht man, daß die verschweißten Einsätze nicht nur die Durchführung des Schweißvorganges erleichtern, sondern auch die therrnoplastischen Profile im Schweißbereich versteifen und verstärken.It then requires welding using a known welding process In this way not only the abutting tabs 6, 7, 8 and 9, but also the surfaces the edges 5 with which the tabs come into contact, together be welded or fused. Based on the shown in Fig. And 4, finished Corner welded connection you can see that the welded inserts are not just the implementation facilitate the welding process, but also the thermoplastic profiles in the Stiffen and reinforce the welding area.
Es ist offensichtlich, daß die Erfindung nicht nur bei der Verschweißung von geschlossenen thermoplastischen Profilen, d.h. z.B. von Profilen ohne Wandunterbrechung, sondern auch bei der Verschweißung von offenen thermoplastischen Profilen, deren Wand unterbrochen ist, wie z»B. It is obvious that the invention does not only apply to welding of closed thermoplastic profiles, i.e. e.g. profiles without wall interruption, but also when welding open thermoplastic profiles, their Wall is interrupted, such as
bei C-Prorilen, U-Profilen oder V-Profilen, anwendbar ist, sofern ein Hohlraum zur Aufnahme des Einsatzes vorhanden ist.is applicable to C-profiles, U-profiles or V-profiles, provided there is a cavity for receiving the insert.
