Abstract

Hollow plastic profiles are fabricated into frame structures, e.g. for doors and windows, by butt welding at the mitres. An allowance must be made for the upsetting length when the sections are cut before the application of heat and pressure to perform the butt joint. All walls of the profiles which are visible when the frame has been installed are provided with a stepped recess along the proposed joint. The dimensions of the recesses are designed to compensate for the volume, displaced by the upsetting operation. The pref. method of producing the recesses is milling in one machining operation with the cutting operation.

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 zunächst unter Berücksichtigung der Abbrennlänge zugeschnitten, die Stoßflächen danach auf Schweißtemperatr erwärmt und die Profilabschnitte sodann unter Herbeiführung der Schweißverbindung gegeneinander gestaucht werden, wie es bei der Herstellung von Rahmenkonstruktionen etwa für Fenster und Türen zur Anwendung kommt, insbesondere für Einkammerprorile, Als nachteilig erweist es sich bei der bekannten Verfahrensweise, daß sich bei der Verschweißung der Profilabschnitte an der Stoßstelle ein Schweißwulst 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. Sichtflächen im Sinne der Erfindung sind die Flächen, die im Einbauzustand des Rahmens sichtbar sind.Plastic hollow profiles Description of the invention relates to a method for pressure welding butting plastic hollow profiles, wherein the profile sections are initially cut to size taking into account the burn-off length, the joint surfaces are then heated to welding temperature and the profile sections then are compressed against each other while causing the welded connection, as it is in the manufacture of frame constructions, for example for windows and doors comes, especially for Einkammerprorile, it proves to be disadvantageous in the known procedure that when the profile sections are welded the joint forms a weld bead, which in any case on the visible surfaces of the Frame is undesirable and must be removed. The removal of the weld bead is cumbersome and expensive, especially at the inner edge of the joint. Visible surfaces In the context of the invention, the surfaces that are visible when the frame is installed are.

Der Erfindung liegt die Aufgabe zugrunde, die Verschweißung von Kunststoff-Hohlprofilen so auszugestalten, daß jedenfalls an den Sichtflächen des Rahmens ein Schweißwulst gar nicht erst entsteht0 Die Aufgabe wird mit einem Verfahren der eingangs umrissenen Art gelöst, das erfindungsgemäß dadurch gekennzeichnet ist, daß die Wandteile der Profilabschnitte mindestens im Bereich der Sichtflächen der Stoßverbindung unter Belassung von einen hinreichenden tragenden Querschnitt gewährleistenden Stoßflachen mit einem der Abbrennlänge entsprechenden Rücksprung versehen werden und die Profilabschnitte unter Eliminierung der Riicksprünge über die Vorsprünge der Wandteile verschwert werden.The invention is based on the task of welding hollow plastic profiles designed in such a way that a weld bead is in any case on the visible surfaces of the frame does not arise in the first place Type solved, which is characterized according to the invention in that the wall parts of the Profile sections at least in the area of the visible surfaces of the butt joint Leaving abutment surfaces ensuring a sufficient load-bearing cross-section be provided with a recess corresponding to the burn-off length and the profile sections with elimination of the recesses over the projections of the wall parts will.

Nach der Erfindung erfolgt die Verschweißung der Profilabschnitte über die über die Rücksprünge vorspringenden Stoßflächen der Profilwandteile. Sich beim Verschweißen allenfalls im Bereich der Sichtflä.chen noch nach außen durchdrückendes Material läßt sich vergleichsweise leicht abstechen.According to the invention, the profile sections are welded via the abutment surfaces of the profile wall parts protruding over the recesses. Themselves When welding, at most in the area of the visible surface, there is still some pushing through to the outside Material can be cut off comparatively easily.

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.The frame corner can in a manner known per se through into the profiles inserted corner brackets are stiffened.

Der Rücksprung kann in einem an den Trenn- bzw. Zuschnitt anschließenden Arbeitsgang durch Hobeln bzw. Fräsen hergestellt rden' 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 für die Herstellung des Rücksprunges. Bestehen zusammenzufugende 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 return can be in a subsequent to the separating or cutting The operation is produced by planing or milling, preferably in one Operation made with the blank, for example with a cutting disc for the blank with at least one associated milling disc of smaller diameter for the Establishing the return. Consists of profile sections to be joined continuously cut to length sections, a cutting disc can be arranged with on both sides Milling disks of smaller diameter are used, with which the joints of 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.
