Fig. 1 zeigt die Ansicht einer Einrichtung zum Ein­ schweißen eines rohrförmigen Teiles 1, wie z. B. ein Kunststoffrohr in den Muffenteil eines Formteiles 2. Fig. 1 shows the view of a device for welding a tubular part 1 , such as. B. a plastic pipe in the socket part of a molded part 2 .

Die Einrichtung weist ein Grundgestell 3 auf, auf welchem in Führungen zwei Schlitten 4, 5 mittels eines Handgriffes 6 und eines nicht näher dargestellten Verstelltriebes von- und gegeneinander verschiebbar angeordnet sind. Zwischen den Schlitten 4 und 5 ist am Grundgestell 1 verschwenkbar eine Heizvorrichtung 7 angeordnet, welche elektrische, heizbare Heizelemente 8 und 9 aufweist.The device has a base frame 3 , on which two slides 4 , 5 are arranged in and out of each other in guides by means of a handle 6 and an adjusting drive, not shown. A heating device 7 , which has electrical, heatable heating elements 8 and 9 , is pivotably arranged on the base frame 1 between the slides 4 and 5 .

Auf dem Schlitten 4 ist eine Einspannvorrichtung 10 für die rohrförmigen Teile angeordnet, welche V-förmig ausgebildete Spannbacken 11 aufweist (siehe Fig. 2). Dadurch ist eine zentrische Spannung von im Durchmesser unterschiedlichen Rohren 1 gewährleistet.A clamping device 10 for the tubular parts, which has V-shaped clamping jaws 11 , is arranged on the slide 4 (see FIG. 2). This ensures a central tension of pipes 1 with different diameters.

Auf dem Schlitten 5 ist eine Einspannvorrichtung 12 für Formteile 2 angeordnet, welche ein Unterteil 13, ein Auflageteil 14 bzw. 40, für die Formteile 2 und eine Spann­ vorrichtung 15 aufweist.On the carriage 5 , a clamping device 12 for molded parts 2 is arranged, which has a lower part 13 , a support part 14 or 40 , for the molded parts 2 and a clamping device 15 .

Das Auflageteil 14 bzw. 40 ist mittels zwei Stiften 16 auf dem Unterteil 13 in positionierter Lage leicht auswech­ selbar aufgesteckt.The support part 14 or 40 is easily exchangeable by means of two pins 16 on the lower part 13 in a positioned position.

Das in den Fig. 1, 3 und 4 gezeigte Auflageteil 14 weist eine im wesentlichen halbschalenförmige Auflagekontur 17 auf, welche der Außenkontur eines als Kreuz-Stück 2 a ausgebildeten Fittings bzw. Formteils 2 angepaßt ist.The support part 14 shown in FIGS . 1, 3 and 4 has an essentially half-shell-shaped support contour 17 , which is adapted to the outer contour of a fitting or molded part 2 designed as a cross piece 2 a .

In dieses Auflageteil 14 können auch T-Stücke 2 b oder Winkel 2 c (siehe Fig. 3), jeweils auch in unterschiedlicher Lage, jedoch zur gleichen Rohrdimension passend, eingelegt werden. Durch die Auflagekontur 17 und die Positionierung des Auflageteils 14 mittels den Stiften 16 ist das Formteil 2 mit einer Muffenachse 30 koaxial zu Rohrachse 31 aus­ gerichtet und weist auch in Achsrichtung eine festgelegte Lage für den Verschiebeweg auf.T-pieces 2 b or angles 2 c (see FIG. 3) can also be inserted into this support part 14 , in each case also in a different position but matching the same pipe dimension. Due to the support contour 17 and the positioning of the support part 14 by means of the pins 16 , the molded part 2 is aligned with a sleeve axis 30 coaxially to the pipe axis 31 and also has a fixed position for the displacement path in the axial direction.

Die Spannvorrichtung 15 weist eine am Schlitten 5 oder am Unterteil 13 angeordnete Haltestange 18 auf, an welcher ein Arm 19 schwenkbar gelagert ist, an dessen anderem Ende ein Gewinde für eine Spannschraube 20 angeordnet ist. Mittels eines Handgriffes 21 ist ein Druckstück 22 der Spann­ schraube 20 gegen das eingelegte Formteil 2 drückbar, wobei gleichzeitig auch das Auflageteil 14 gegen das Unterteil gedrückt und somit in positionierter Lage festgehalten wird.The clamping device 15 has a holding rod 18 arranged on the slide 5 or on the lower part 13 , on which an arm 19 is pivotably mounted, at the other end of which a thread for a clamping screw 20 is arranged. By means of a handle 21 , a pressure piece 22 of the clamping screw 20 can be pressed against the inserted molded part 2 , and at the same time the support part 14 is pressed against the lower part and is thus held in position.

Eine spezielle Befestigung der Auflageteile 14 ist somit nicht erforderlich, wodurch ein rasches Umrüsten für Formteile einer anderen Dimension oder/und anderen Form gewährleistet ist.A special attachment of the support parts 14 is therefore not necessary, which ensures a quick changeover for molded parts of another dimension and / or different shape.

Die Fig. 5 zeigt eine Ausführungsvariante eines Auflageteils 14 a, deren Auflagekontur 17 a zur Aufnahme eines 45°-Winkels ausgebildet ist. FIG. 5 shows a variant embodiment of a support portion 14 a whose contour support a is adapted to receive a 45 ° angle 17th

Die Fig. 6 zeigt eine weitere Ausführungsvariante eines Auflageteils, dessen Auflagekontur 17 b zur Aufnahme von Muffen und Bundbuchsen ausgebildet ist, wobei in einer halbringförmigen Nute 23 der Bund der Bundbuchse zu liegen kommt. Fig. 6 shows a further embodiment of a support member whose support contour 17 b for receiving sleeves and flange bushings is formed, wherein comes to lie in a semi-annular groove 23 of the collar of the collar bushing.

Mit drei unterschiedlichen Auflageteilen 14 für jeweils eine Rohrdimension kann somit das gebräuchlichste Formteil, bzw. Fitting-Programm für ein Rohrleitungssystem in genau fixierte Lage zum Verschweißen in der beschriebenen Ein­ richtung eingespannt werden.With three different support parts 14 for each pipe dimension, the most common molded part or fitting program for a piping system can be clamped in a precisely fixed position for welding in the described direction.

Da das Druckstück der Spannschraube nicht im Einsteck- bzw. Schweißbereich der Formteile zu liegen kommt, können auch in diesem Bereich keine Deformierungen am Formteil ent­ stehen.Since the pressure piece of the clamping screw is not in the Welding area of the molded parts can also lie no deformations on the molded part in this area stand.

Selbstverständlich kann auch die zweite auf dem Schlitten 4 angeordnete Einspannvorrichtung, gleich wie beschrieben, zur Aufnahme von Formteilen mit einem Auflageteil ausge­ bildet werden, so daß zwei Formteile miteinander ver­ schweißt werden können.Of course, the second arranged on the carriage 4 clamping device, same as described, for receiving molded parts with a support part are formed so that two molded parts can be welded together ver.

Die Fig. 7 und 8 zeigen ein Auflageteil 40, welches aus einer Grundplatte 41, zwei auf diese aufgesetzte Kontur­ teile 42 und aus einem Abstützteil 47 besteht. Die beiden Konturteile 42 weisen die für eine bestimmte Formteil­ abmessung halbzylinderförmige Auflagekontur 17 auf und sind mittels Schrauben 44 in positionierter Lage auf der Grund­ platte 41 befestigt. Gemäß Fig. 7 sind zwei Konturteile 42 in einem Winkel von 45° zueinander angeordnet, wodurch das Auflageteil 40 zur Aufnahme eines 45°-Winkels ausgebildet ist und an Stelle des in Fig. 5 gezeigten Auflageteils 14 a verwendet wird. FIGS. 7 and 8 show a supporting part 40, which consists of a base plate 41, two parts to this patch contour 42 and a supporting part 47th The two contour parts 42 have the semi-cylindrical support contour 17 for a specific molded part dimension and are fastened by means of screws 44 in a positioned position on the base plate 41 . According to FIG. 7, two contour parts 42 are arranged at an angle of 45 ° to one another, as a result of which the support part 40 is designed to accommodate a 45 ° angle and is used instead of the support part 14 a shown in FIG. 5.

Fig. 9 zeigt ein Auflageteil 40 a mit einer Grundplatte 41 a und vier Konturteilen 42, welche jeweils unter 90° zuei­ nander auf der Grundplatte 41 a befestigt sind. Fig. 9 shows a support part 40 a with a base plate 41 a and four contour parts 42 , which are each attached at 90 ° to each other on the base plate 41 a .

Dieses Auflageteil 40 a ist wie das zur Fig. 3 beschriebene Auflageteil zur Auflage von 90°-Winkeln, T-Stücken und Kreuzstücken geeignet.This support part 40 a is, like the support part described for FIG. 3, suitable for supporting 90 ° angles, T-pieces and cross pieces.

Fig. 10 zeigt ein Auflageteil 40 b zur Auflage von glatten Muffen, welches aus einer Grundplatte 41 b, zwei Kontur­ teilen 42 und einem Anschlagteil 45 besteht. Fig. 10 shows a support part 40 b for supporting smooth sleeves, which divide from a base plate 41 b , two contours 42 and a stop part 45 .

Für die drei verschiedenen Auflageteile 40, 40 a und 40 b können für die Formteile jeweils einer Rohrdimension die gleichen Konturteile 42 mit einer Auflagekontur 17 ver­ wendet werden, wobei für die unterschiedlichen Formen lediglich eine unterschiedliche Anordnung auf den Grund­ platten 41, 41 a und 41 b vorgesehen ist. Dies gewährleistet eine einfache und rationelle Herstellung der Auflageteile.For the three different support parts 40 , 40 a and 40 b , the same contour parts 42 with a support contour 17 can be used for the molded parts in each case one pipe dimension, whereby for the different shapes only a different arrangement on the base plates 41 , 41 a and 41 b is provided.
