Abstract

In the zone of the surfaces which will be visible when a welded butt joint is made between hollow profiles of synthetic material, the edges to form the visible joint are set back relatively to the edges to be welded, by an amt. corresp. to the material required for the weld. The projecting edges of the profile are then raised to the welding temp and the profiles are pressed together so that the setting back of the visible edges is eliminated and the welded seam is formed underneath. Setting back of the edges is effected by a milling cutter, and the machining to size and the setting back are carried out in one operation. The walls of the core forming the welds are thicker than the circumferential walls of the profile, and the distance of these walls from the visible outer walls is such that the welded seam made lies against the butting edges of the outer walls which are filled by a glue. Frames for doors and windows can thus be assembled without it being necessary to have an additional operation for trimming off the visible welded seams.

Description

Verfahren zum Verschweißen stoßenderProcess for welding butt joints

Kunststoff-Hohlprofile Beschreibung Die Erfindung betrifft ein Verfahren zum Preßverschweißen stoßender Kunststoff-Hohlprofile, wobei die Profilabschnitte zunschst unter Berücksichtigung der Abbrennlänge zugeschnitten, die Stoß flächen danach auf Schweißtemperatur erwärmt und die Profilabschnitte sodann unter Herbeiführung der Schweißverbindung gegeneinander gestaucht werden, wie es insbesondere bei der Herstellung von Rahmenkonstruktionen etws liir Fenster und Türen zur Anwendung kommt.Plastic hollow profiles Description of the invention relates to a method for pressure welding butting plastic hollow profiles, wherein the profile sections are first cut to size taking into account the burn-off length, the joint surfaces are then heated to welding temperature and then the profile sections are compressed against each other while causing the welded connection, as it is especially in the production of frame constructions for windows and Doors is used.

Als nachteilig erweist es sich bei der bekannten Verfahrensweise, daß sich bei der Verschweißung der Rofilabschnitte an der Stoßstelle ein chweirhnilst ausbildet, der Jedenfalls an den Sichtflächen des Rahmens unerwünscht ist und entfernt werden muß. Die Entfernung des Schweißwulstes ist zumal an der Innenkante des Stoßes beschwerlich und aufwendig.It proves to be disadvantageous in the known procedure, that there is a chweirhnilst when the profile sections are welded at the joint forms, which is undesirable in any case on the visible surfaces of the frame and removed must become. The removal of the weld bead is especially on the inside edge of the joint arduous and time-consuming.

Sichtflächen im Sinne der Erfindung sind die Flächen, die im Einbauzustand des Rahmens sichtbar sind.Visible surfaces within the meaning of the invention are the surfaces that are in the installed state of the frame are visible.

Der Erfindung liegt die Aufgabe zugrunde, die Verschweißung von Kunststoff-Hohlprofilen so auszugestaiten, daß jedenfalls an den Sichtflächen des Rahmens ein Schweißwulst gar nicht erst entsteht.The invention is based on the task of welding hollow plastic profiles in such a way that in any case a weld bead on the visible surfaces of the frame does not arise in the first place.

Die Aufgabe wird mit einem Verfahren der eingangs umrissenen Art gelöst, das erfindungsgemäß dadurch gekennzeichnet ist, daß die Profilabschnitte mindestens im Bereich der Sichtflächen der Stoßverbindung unter Belassung von einen hinreichenden tragenden Querschnitt gewährleistenden Stoffschluß eingehenden Stoßflächen mit einem der Abbrennlänge entsprechenden Rücksprung versehen werden und die Profilabschnitte unter Eliminierung der Rücksprünge über die vorspringenden Profilteile verschweißt werden.The task is solved with a method of the type outlined above, which is characterized according to the invention in that the profile sections at least in the area of the visible surfaces of the butt joint leaving a sufficient one load-bearing cross-section ensuring material connection incoming abutment surfaces with a the setback corresponding to the burn-off length and the profile sections welded over the protruding profile parts while eliminating the recesses will.

Nach der Erfindung erfolgt die Verschweißung der Profilabschnitte im wesentlichen über die über die Rticksprünge vorspringenden Stoßflächen der Profile in an sich bekannter Weise, während im Bereich der Rücksprünge ein merkliche Verschweißung nicht erfolgt und in diesem Bereich somit auch kein Schweißwulst entsteht, der entfernt werden müßte.According to the invention, the profile sections are welded essentially via the abutment surfaces of the profiles protruding over the recesses in a manner known per se, while in the area of the recesses there is a noticeable weld does not take place and therefore no weld bead arises in this area, which is removed would have to be.

Das Verfahren eignet sich insbesondere für die Verschweißung von Mehrkammerprcfilen, bei denen sich die Kernkammer für die Verschweißung der Profile anbietet. Dabei kann dann im Bedarfsfall auch ein umlaufender Rücksprung vorgesehen werden.The process is particularly suitable for welding multi-chamber profiles, in which the core chamber for the Welding of the profiles offers. If necessary, a circumferential return can also be provided will.

Hierfür werden vorzugsweise Profile eingesetzt, bei denen dieWandteile des Kerns stärker dimensioniert sind als die Umfangswandteile der Profile, Das schließt die zusätzliche Verschweißung der Profilabschnitte im Bereich der der Ansicht nicht zugänglichen Umfangswandteile nicht aus.For this purpose, profiles are preferably used in which the wall parts of the core are larger than the peripheral wall parts of the profiles, that includes the additional welding of the profile sections in the area of the view is not accessible peripheral wall parts.

Vorzugsweise werden Mehrkannerprofile eingesetzt, bei denen der Abstand der Kernwandteile von den Umfangswandteilen so bemessen ist, daß der beim Verschweißen der Profilabschnitte entstehende Schweißwulst gegen die Umfangswandteile den Stoß überdeckend zur Anlage kommt. Nach einer speziellen Ausführungsform werden Profile vorgesehen, bei denen im Abstand von den der Ansicht zugänglichen Umfangswandteilen ein sich iiber die gesamte Länge dieser Umfangswandteile erstreckendes, rücksprlmgfreies, an der Verschweißung teilnehmendes Wandteil und/oder Stege vorgesehen werden, deren Abstand von den Umfangswandteilen so bemessen ist, daß der Schweißwulst sich gegen das Umfangswandteil anlegt. Dabei erübrigt sich dann das Abdichten des Stoßes etwa durch Verkleben der Umfangswandteile.Preferably, multi-scanner profiles are used in which the distance the core wall parts is dimensioned by the peripheral wall parts so that the welding the weld bead produced by the profile sections against the peripheral wall parts the joint comes to the plant covering. According to a special embodiment, profiles provided, in which at a distance from the view accessible peripheral wall parts one that extends over the entire length of these circumferential wall parts and is free of rebound, participating in the welding wall part and / or webs are provided, the Distance from the peripheral wall parts is dimensioned so that the weld bead is against the peripheral wall part applies. Sealing of the joint is then unnecessary by gluing the peripheral wall parts.

Das Verfahren ist anwendbar auf fluchtende wie auch auf Gehrung zusammengesetzte Profilabschnitte.The method can be used for aligned as well as mitred assemblies Profile sections.

Die Rahmenecke kann in an sich bekannter Weise durch in die Profile eingefügte Eckwinkel ausgesteift werden, Dabei können auch flache Winkel eingesetzt werden. Bei im Bereich des Stoßes Ausnehmungen aufweisenden Eckwinkeln drückt sich der sich beim Verschweißen der Profilabschnitte ausbildende Schweißwulst in diese Ausnehmungen.The frame corner can in a manner known per se through into the profiles Inserted corner angles can be stiffened. Flat angles can also be used will. In the case of corner angles having recesses in the area of the joint, there is pressure the welding bead that forms when the profile sections are welded into them Recesses.

Der Wicksprung kann in einem an den Trenn- bzw. Zuschnitt anschließenden Arbeitsgang durch Hobeln bzw. Fräsen hergestellt werden, vorzugsweise wird er in einem Arbeitsgang mit dem Zuschnitt hergestellt, etwa mit einer Trennscheibe für den Zuschnitt mit mindestens einer ihr zugeordneten Frässcheibe geringeren Durchmessers fürdie Herstellung des RUcksprunges. Bestehen zusammenzufügende Profilabschnitte aus fortlaufend abgelängten Abschnitten, kann eine Trennscheibe mit zu beiden Seiten angeordneten Frässcheiben geringeren Durchmessers verwendet werden, womit die Stöße zweier Abschnitte in einem Arbeitsgang erfindungsgemäß vorbereitet werden können.The winding jump can follow the separating or cutting edge Operation can be produced by planing or milling, preferably it is in produced in one operation with the blank, for example with a cutting disc for the blank with at least one associated milling disc of smaller diameter for making the return. There are profile sections to be joined from continuously cut sections, a cutting disc can be made with on both sides arranged milling disks of smaller diameter are used, with which the joints two sections can be prepared according to the invention in one operation.

Die Erfindung ist in der Zeichnung weitergehend erläutert.The invention is further explained in the drawing.

Der Schweißwulst 13 muß vor dem Einbau des Rahmens Jedenfalls im Bereich der Sichtflächen 14 noch entfernt werden.In Figure 1 is one of two welded together plastic hollow profile sections ll, 12 conventionally produced Tiahmenecke in the raw state, i.e. with still existing weld bead 13 is shown. The welding bead 13 must be installed before installation of the frame must be removed in the area of the visible surfaces 14 in any case.

Die interessierenden Sichtflächen werden etwa bei Profilen entsprechend Figur 2 gebildet von den Umfangswandteilen 211, 213 (teilweise) und 214.The visible surfaces of interest are corresponding, for example, with profiles FIG. 2 formed by the peripheral wall parts 211, 213 (partially) and 214.

Nach der Erfindung werden die Stoßflächen 211 bis 2162 der Umfangswandteile 211 bis 216 gegenüber den Kernwandteilen 217 bis 2.20 abgesetzt, so daß die Verschweißung der Profilabschnitte 21, 22 nur über dieKernwandteile 217 bis 220 erfolgt, sich also nur entlang den Kernwandteilen 217 bis 220 ein Schweißwulst 23 ausbildet. Der Rücksprung x der UmSangswandteile 211 bis 216 ist dabei so bemessen, daß die Umfangswandteile 211 bis 216 der verschweißten Profilabschnitte 21, 22 sich stoßen.According to the invention, the abutment surfaces 211 to 2162 of Perimeter wall parts 211 to 216 offset from the core wall parts 217 to 2.20, so that the weld of the profile sections 21, 22 only takes place via the core wall parts 217 to 220 that is, a weld bead 23 is formed only along the core wall parts 217 to 220. Of the Setback x of the circumferential wall parts 211 to 216 is dimensioned so that the circumferential wall parts 211 to 216 of the welded profile sections 21, 22 butt against each other.

Die Umfangswandteile 211 bis 216 der verschweißten Profilabschnitte 21, 22 können miteinander verklebt sein. Die Abdichtung des Stoßes insbesondere im Bereich der Sichtflächen kann aber auch durch den die entsprechenden Umfangswandteile hinterfangenden Schweißwulst 23 erfolgen. Dazu ist dann beispielsweise im Bereich des Umfangswandteiles 215 und der Stege 221, 222 kein RUcksprung vorgesehen, so daß diese Elemente an der Verschweißung teilnehmen und der sich dabei ausbildende Schweißwulst den Stoß der Umfangswandteile 213, 214 über die ganze Länge hinterfängt.The peripheral wall parts 211 to 216 of the welded profile sections 21, 22 can be glued together. The sealing of the joint in particular in the area of the visible surfaces, however, the corresponding peripheral wall parts can also be used behind catching weld bead 23 take place. This is then, for example, in the area of the peripheral wall part 215 and the webs 221, 222 no setback is provided, so that these elements take part in the welding and that which is formed in the process Welding bead catches the joint of the peripheral wall parts 213, 214 over the entire length.
