Beschreibung description
Die Erfindung betrifft eine Einrichtung zum Ein-schweissen eines rohrförmigen Kunststoffteiles in ein Kunststoff-Formteil, wie sie im Oberbegriff von Anspruch 1 gekennzeichnet ist. The invention relates to a device for welding a tubular plastic part into a plastic molded part, as characterized in the preamble of claim 1.
Einrichtungen der vorgängig genannten Art sind z.B. durch die DE-B 2 734 911 bekanntgeworden. Die DE-U 8 207 270 zeigt eine Einrichtung, bei welcher die als Fitting ausgebildeten Formteile in deren zylindrischen Muffenpartie in an den Durchmesser angepassten Spannbacken festgespannt werden. Devices of the type mentioned above are e.g. through DE-B 2 734 911. DE-U 8 207 270 shows a device in which the shaped parts designed as a fitting are clamped in their cylindrical socket part in clamping jaws which are adapted to the diameter.
Eine einwandfreie Spannung ohne Verformung der Muffenpartie ist hierbei nur dann möglich, wenn hierbei das Formteil eine genügend lange zylindrische Muffenpartie aufweist. Für die axiale Positionierung und Abstützung ist mindestens ein verstellbarer Anschlag erforderlich, wobei durch Fehlein-steliungen ungenügende Muffen-Schweissverbin-dungen entstehen können. Proper tensioning without deformation of the socket section is only possible if the molded part has a sufficiently long cylindrical socket section. At least one adjustable stop is required for axial positioning and support, whereby inadequate socket-welded connections can result from incorrect settings.
Aufgabe der vorliegenden Erfindung ist die Schaffung einer Einrichtung der eingangs genannten Art, mittels welcher Formteile unterschiedlichster Art in einwandfrei positionierter Lage auch in axialer Richtung gehalten werden, ohne dass sie durch das Spannen deformiert werden. The object of the present invention is to create a device of the type mentioned at the outset, by means of which molded parts of the most varied types are held in a perfectly positioned position and also in the axial direction without being deformed by the tensioning.
Erfindungsgemäss wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1 gelöst. According to the invention, this object is achieved by the characterizing features of claim 1.
Besonders vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet. Particularly advantageous embodiments of the invention are characterized in the dependent claims.
Durch die erfindungsgemässe Ausbildung eines Auflageteils der Einspannvorrichtung für Formteile ist deren genaue Positionierung für das Ver-schweissen mit einem rohrförmigen Teil gewährleistet, wobei beim Spannen keine Veränderung der Rundheit der Muffenpartie des Formteils erfolgt. The design according to the invention of a support part of the clamping device for molded parts ensures its precise positioning for welding to a tubular part, with no change in the roundness of the socket part of the molded part during clamping.
Die Erfindung ist in den beiliegenden Zeichnungen beispielsweise dargestellt und nachfolgend beschrieben. Es zeigen: The invention is illustrated in the accompanying drawings, for example, and described below. Show it:

Fig. 2 eine Ansicht in Richtung A von Fig. 1, 2 is a view in the direction A of Fig. 1,
Fig. 3 eine Draufsicht des Auflageteils in Richtung B von Fig. 1 3 shows a top view of the support part in direction B of FIG. 1
Fig. 4 eine Seitenansicht des Auflageteils in Richtung C von Fig. 1 4 shows a side view of the support part in the direction C of FIG. 1
Fig. 5 eine Draufsicht auf eine Ausführungsvariante eines Auflageteils gemäss Fig. 3 und 5 is a plan view of an embodiment variant of a support part according to FIGS. 3 and
Fig. 6 eine weitere Ausführungsvariante eines Auflageteils in Draufsicht. Fig. 6 shows a further embodiment variant of a support part in plan view.
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, e.g. 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, 5 ist am Grundgestell 1 verschwenkbar eine Heizvorrichtung 7 angeordnet, welche elektrisch 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 electrically heated heating elements 8 and 9, is pivotably arranged on the base frame 1 between the slides 4, 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 On the carriage 5 is a jig
12 für Formteile 2 angeordnet, welche ein Unterteil 12 arranged for molded parts 2, which is a lower part
13 ein Auflageteil 14 für die Formteile 2 und eine Spannvorrichtung 15 aufweist. 13 has a support part 14 for the molded parts 2 and a clamping device 15.
Das Auflageteil 14 ist mittels zwei Stiften 16 auf dem Unterteil 13 in positionierter Lage leicht auswechselbar aufgesteckt. The support part 14 is easily interchangeably attached to the lower part 13 by means of two pins 16 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 2a ausgebildeten Fitting bzw. Formteil 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 2a.
In dieses Auflageteil 14 können auch T-Stücke 2b oder Winkel 2c (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 ausgerichtet und weist auch in Achsrichtung eine festgelegte Lage für den Verschiebeweg auf. T-pieces 2b or angles 2c (see FIG. 3) can also be inserted into this support part 14 in different positions, but in a suitable manner for 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 coaxial 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 Spannschraube 20 gegen das eingelegte Formteil 2 drück-bar, 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, the support part 14 also being pressed against the lower part and thus being 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 Auflageteiis 14a, deren Auflagekontur 17a zur Aufnahme eines 45 Grad-Winkels ausgebildet ist. 5 shows a variant of a support part 14a, the support contour 17a of which is designed to accommodate a 45 degree angle.
Die Fig. 6 zeigt eine weitere Ausführungsvariante eines Auflageteils, dessen Auflagekontur 17b zur Aufnahme von Muffen und Bundbuchsen ausgebildet ist, wobei in einer haibringförmigen Nute 23 der Bund der Bundbuchse zu liegen kommt. FIG. 6 shows a further embodiment variant of a support part, the support contour 17b of which is designed to accommodate sleeves and collar bushings, the collar of the collar bushing being located in a ring-shaped groove 23.
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 Ver-schweissen in der beschriebenen Einrichtung eingespannt werden. With three different support parts 14 for each pipe dimension, the most common molded part or fitting program for a pipe system can be clamped in a precisely fixed position for welding in the described device.
Da das Druckstück der Spannschraube nicht im Einsteck- bzw. Schweissbereich der Formteile zu liegen kommt, können auch in diesem Bereich keine Deformierungen am Formteil entstehen. Since the pressure piece of the clamping screw does not come to rest in the insertion or welding area of the molded parts, no deformations can occur on the molded part in this area either.
Selbstverständlich kann auch die zweite auf dem Schlitten 4 angeordnete Einspannvorrichtung gleich wie beschrieben zur Aufnahme von Formteilen mit einem Auflageteil ausgebildet werden, so dass zwei Formteile miteinander verschweisst werden können. Of course, the second clamping device arranged on the slide 4 can also be designed to hold molded parts with a support part, as described, so that two molded parts can be welded to one another.
