Abstract

Pressure-plates for a plastics butt-welding machine are used both for forming the weld and also for simultaneously removing the projecting weld beading; the plates exactly fit along the welded joint and are sharply cut back externally, resulting in a sharp cutting edge which removes the beading. Specif., the plates grip the profiles before assembly, covering them up to the finished dimension, leaving only a small length of the profile extending, to form the weld. When the plates are brought together, this material is squeezed inwards and outwards, the outward parts being cut off by the sharp edges of the plates.

Description

Beschreibung der Erfindung: Andruckplatten für Kunststoff= stumpfschweißmaschinen.Description of the invention: Pressure plates for plastic = butt welding machines.

Die Erfindung betrifft Andruckplatten für Kunststoff stumpf schweißmaschinen zum Schweißen mit gleichzeitigem Entfernen der sichtbaren Schweißwulst bei Kunststoffprofilen0 Aus solchen Kunststoffprofilen werden Fenster hergestellt.The invention relates to pressure plates for plastic butt welding machines for welding with simultaneous removal of the visible welding bead from plastic profiles0 Windows are made from such plastic profiles.

Die Eckverbindungen der Fensterrahmen werden stumpf auf Geh= rung zusammengeschweißt.Durch den Schweißvorgang entsteht eine Schweißwulst,die an der gesamten Außenkante und Fläche der Schweißnaht sichtbar ist.Diese sichtbare Schweißwulst muß nach dem Abkühlen entfernt werden.Nach dem heutigen Stand der Technik geschieht dies mit großem Zeitaufwand teils manuell und teils maschinell,z.B.durch abstechen,abfräsen,abschleifen.The corner connections of the window frames are butted to the joint The welding process creates a weld bead that is attached to the The entire outer edge and surface of the weld seam is visible must be removed after cooling down. This is done according to the current state of the art This takes a lot of time, partly manually and partly by machine, e.g. by parting, milling, grinding.

Der Erfindung liegt die Aufgabe zugrunde1 die entstehende Schweiß= wulst an den sichtbaren Kanten und Flächen während des Schweiß vorgangs zu entfernen,ohne daß die Oberfläche im aufgeheizten Bereich einfällt.The invention is based on the task of the resulting sweat = bead on the visible edges and surfaces can be removed during the welding process without that the surface collapses in the heated area.

Diese Aufgabe wird erfindermäßig dadurch gelöst,daß die zwei zu verschweißenden Kunststoffprofile mit Andruckplatten fest= gespannt werden,die im Endstand des Zusammenschiebens dicht auf Gehrung zusammenpassen.Die Gehrung der Andruckplatten muß genau mit der fertigen Schweißnaht übereinstimmen.Die Andruck= platten sind im Bereich der Gehrung mindestens 45 nach hinten abgefast,so daß sich nur die Spitzen berühren.Hierdurch entsteht eine scharfe Kante,die das austretende Kunststoffmaterial beim Zusammenschieben wegschneidet.Weil die Kunststoffprofile bis zum Fertigmaß von den Andruckplatten bedeckt und angedrückt Erfindung: Andruckplatten für Kunststoffstumpfschweißmaschinen angedrückt werden,staucht sich das gummielastische Kunststoff material im kritischen Bereich der aufgeheizten Schweißnaht nach innen und kann deshalb nach dem Abkühlen nicht mehr ein= fallen.Fei'ner wird durch die bestimmte Anordnung der Andruck= platten das Entstehen der Schweißwulst auf den Bereich der Materialzugabe beschränkt.This object is achieved according to the invention in that the two to be welded Plastic profiles with pressure plates firmly = are clamped in the final position of the pushing together The miter of the pressure plates must exactly match the The pressure plates are in the area of the miter Chamfered at least 45 cm backwards so that only the tips touch each other creates a sharp edge, which the emerging plastic material when pushed together Because the plastic profiles are up to the finished size from the pressure plates covered and pressed Invention: Pressure plates for plastic butt welding machines are pressed, the rubber-elastic plastic material compresses in the critical Area of the heated weld seam inwards and can therefore after cooling no longer fall in. Fei'ner is due to the specific arrangement of the pressure plates the creation of the weld bead is limited to the area of the material allowance.

Die durch die Erfindung erzielbaren Vorteile: 1. Durch die bestimmte Form und Anordnung der Andruckplatten wird das gummielastische Material im kritischen Bereich der aufgeheizten Schweißzone nach innen gestaucht und kann des halb nach dem Abkühlen nicht mehr einfallen.The advantages that can be achieved by the invention: 1. By the specific The rubber-elastic material is critical in terms of the shape and arrangement of the pressure plates The area of the heated welding zone is compressed inwards and can therefore move can no longer think of cooling.

2. Das Entstehen der Schweißwulst wird auf den Bereich der Materialzugabe fixiert. 2. The creation of the weld bead is due to the area of the material allowance fixed.

3. Beim Zusammenschieben wird die noch entstehende Schweiß wulst weggeschnitten,weshalb ihr Entfernen nach dem Ab= kühlen entfällt. 3. When pushing together the still emerging sweat will bulge cut away, which is why it is not necessary to remove it after cooling.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dar= gestellt und wird wie folgt näher beschrieben.An embodiment of the invention is shown in the drawing = and is described in more detail as follows.

Es zeigen Fig. 1 bis 4 die Arbeitsweise der Andruckplatten im Vertikalschnitt,Fig. 5 bis 8 im Horizontalschnitt.1 to 4 show the operation of the pressure plates in vertical section, FIG. 5 to 8 in horizontal section.

( schematisch dargestellt ) Fig. 1 zeigt die fertig eingestellten Andruckplatten vor dem Schweißvorgang.Es ist der Endstand des Zusasnenschiebens.(shown schematically) Fig. 1 shows the fully adjusted Pressure plates before the welding process. It is the final stage of pushing together.

Fig. 2 zeigt das fertig eingespannte Kunststoffprofil.Hier muß die Materialzugabe über die Spitzen der Andruckplatten vorstehen.Fig. 2 shows the fully clamped plastic profile Material allowance protrude over the tips of the pressure plates.

Fig. 3 zeigb die Profile sind an den eingefahrenen Schweiß= spiegel angedrückt.Fig. 3 shows the profiles are on the retracted welding mirror pressed on.

Fig. 4 zeigt die fertige Schweißnaht nach dem Zusammenschieben.Fig. 4 shows the finished weld after being pushed together.

Hier stimmt der Endstand der Andruckplatten genau mit dem auf Fig. 1 überein.Here the final position of the pressure plates exactly matches that shown in Fig. 1 match.

Erfindung: Andruckplatten für Kunststoffstumpfschweißmaschinen Fig. 5 zeigt die fertig eingestellten Andruckplatten vor dem Schweißvorgang.Es ist der Endstand des Zusammenschiebens.Invention: pressure plates for plastic butt welding machines Fig. 5 shows the completely set pressure plates before the welding process. It is the Final result of the collapse.

Fig. 6 zeigt das fertig eingespannte Kunststoffprofil.Hier muß die Materialzugabe über die Spitzen der Andruckplatten vorstehen.Fig. 6 shows the fully clamped plastic profile Material allowance protrude over the tips of the pressure plates.

Fig. 7 zeigt die Profile sind an den eingefahrenen Schweiß= spiegel angedrückt.Fig. 7 shows the profiles are on the retracted welding mirror pressed on.

Fig. 8 zeigt die fertige Schweißnaht nach dem Zusammenschieben.Fig. 8 shows the finished weld after being pushed together.
