  Vorrichtung zum Verschweissen von Kunststoffrohren
Es ist bekannt, Rohre aus thermoplastischen Kunststoffen durch   Re ibungs schweissen    zu verbinden.



  Dieses Verfahren wird z. B. verwendet, um Bördelringe oder feste Flanschen mit Rohrenden zu verschweissen. Die benutzten Vorrichtungen haben aber den Nachteil, dass sie nur in der Werkstatt verwendet werden können.   An Montagestellen    und zwar besonders zur Verbindung bereits verlegter Rohre sind sie nicht zu gebrauchen.



   Die erfindungsgemässe Vorrichtung soll die Aufgabe lösen, die genannten Nachteile zu vermeiden.



  Mit ihr sollen   Kunststoffrohre    an beliebiger   Stelle,    d. h. in der Werkstatt oder am Montageort durch Reibungsschweissen schnell und sicher verbunden werden.



   Dies wird mit einer Vorrichtung erreicht, die aus einem Gehäuse, einem in dem Gehäuse gelagerten Winkelantrieb mit einem zweiteiligen, das eine der zu verschweissenden Rohre   umfassenden    grossen Kegel rad und einem von einer Welle angetriebenen kleinen Kegelrad sowie aus einem am Gehäuse gelagerten, gegen das genannte Rohr über eine zweiteilige, durch zwei Rohrschellen mit den Rohrenden verbundene Halterung abgestützten, gegabelten Hebei besteht, mit dessen Hilfe ein mit dem grossen Kegelrad kraftschlüssig durch Reibung verbundener Zwischenring während der durch die Welle über die Kegelräder bewirkten Drehbewegung an die beiden zu verschweissenden Rohrenden bzw. an das zu verschweissende Rohr sowie an das Gegenstück angedrückt und mit ihnen verschweisst wird.



   Der wesentliche   Erfindungsgedanke    besteht demnach darin, dass ein Zwischenring z. B. aus   thermo-    plastischem Kunststoff, der an den beiden zu verschweissenden Rohrenden unter Druck anliegt, zur Drehung gebracht wird. Dabei erwärmt er sich zusammen mit den anliegenden Gegenflächen auf   Schweisshitze.    Nach dem   Erkalten    bilden Zwischenring und Rohrenden eine druckdichte, homogene Verschweissung. Diese hat gegenüber den bisher bekannten, mit metallischen Teilen arbeitenden Verbindungen den Vorteil, dass sie in allen ihren Teilen die gleiche Korrosionsfestigkeit besitzt wie die Rohre selbst, da Zwischenring, Armatur und Rohre aus dem gleichen Werkstoff bestehen.



   Die beiden zu verschweissenden Rohrenden werden durch eine zweiteilige Halterung, welche vorteilhaft das Gehäuse teilweise umgibt, mittels zweier Rohrschellen festgehalten.



   Zur Durchführung der Montage sind zweckmässig Gehäuse und grosses Kegelrad geteilt.



   Die Vorrichtung wird über die Kegelräder durch eine Welle angetrieben. Diese kann als biegsame Welle ausgeführt werden.



   In den Abbildungen ist eine zweckmässige Aus  führungsforna    der   erfindungsgemässen    Vorrichtung   dargestellt.    Fig. 1 zeigt einen Längsschnitt, Fig. 2 einen hierzu um 900 gedrehten Schnitt durch die Vorrichtung in axialer Richtung.



   Die Vorrichtung besteht aus einem zweiteiligen Gehäuse 1 (Fig. 1), in dem ein kleines Kegelrad 2 mit einem zylindrischen Schaft 3 mittels der Kugellager 4 bis 6 gelagert ist. Die beiden Kugellager 5 und 6 werden durch eine Distanzhülse 7 voneinander getrennt und durch die Sprengringe 8 und 9 in ihrer Lage festgehalten.



   Das kleine Kegelrad 2 greift in ein zweiteiliges grosses Kegelrad 10 ein. Dieses wird an zwei kegeligen Flächen 11 und 12 im Gehäuse 1 gehalten bzw. gelagert. Mit einer dritten Kegelfläche 13 erfasst das grosse Kegelrad 10 ein Verbindungsstück 14. Zur Erhöhung der in der   Kegellläche    13 übertragenen Kraft kann die Fläche 13 im grossen Kegelrad mit Mitnehmern versehen sein.  



   An dem Gehäuse 1 ist ein Hebel 15 befestigt.



  Er wird durch eine Feder 16 nach aussen gedrückt.



  Bei Betätigung drückt er seinerseits mit seinem vorderen Rand 17 gegen eine metallische Schelle   18.    welche um das zu verschweissende Rohr 19 geklemmt wird. Das zweite zu verschweissende Rohrende bzw. das Zwischenstück (Armatur) 24 wird mit einer zweiteiligen Halterung 20, welche gelenkig in der   Schere    18 gelagert ist, über eine untere Schelle 25 befestigt (Fig. 2).



   Die Kegelräder   werden    über den zylindrischen Schaft 3 des kleinen Kegelrades angetrieben. Hierzu ist in dem zylindrischen Schaft 3 ein Schlitz 26 vorgesehen, in den ein passendes Kopfstück einer biegsamen Welle 21 eingreift. Die biegsame Welle wird in einer Muffe 22 geführt, welche mittels einer    Überwurfmutter r 23 mit dem Gehäuse 1 verbunden    wird.



   Bei dem Verschweissen wird der konische Zwischenring 14 aus Kunststoff, welcher an der Kegeifläche 13 des grossen Kegelrades 10 anliegt, durch die biegsame Weile 21 über das kleine Kegelrad 2 in Rotation versetzt. Durch Betätigung des Hebels 15 wird der Zwischenring 14 axial in das Zwischenstück 24 sowie gegen das Rohr 19 gedrückt. Hierbei stützt sich der Hebel 15 gegen die Schelle 18 bzw. über die Halterung 20 und die untere Schelle 25 gegen das   Zwischenstück    24 ab. Die beiden zu verschweissenden Teile, das Rohr 19 und das Zwlschenstück 24, werden durch die Halterung 20 bzw. die Schellen 18 und 25 in ihrer Lage gehalten. Nach dem Verschweissen und   Erkalten    der Verbindung werden die Schellen 18 und 25 gelöst; danach kann die gesamte Vorrichtung, nämlich das zweiteilige Kegelrad 10, von der entstandenen Verbindung abgenommen werden.   



  
 



  Device for welding plastic pipes
It is known to connect pipes made of thermoplastics by friction welding.



  This method is z. B. used to weld crimp rings or fixed flanges with pipe ends. The devices used have the disadvantage that they can only be used in the workshop. They are not to be used at assembly points, especially for connecting pipes that have already been laid.



   The device according to the invention is intended to solve the problem of avoiding the disadvantages mentioned.



  With it, plastic pipes should be placed anywhere, i. H. be connected quickly and securely in the workshop or at the assembly site by friction welding.



   This is achieved with a device that consists of a housing, an angular drive mounted in the housing with a two-part, the one of the pipes to be welded comprehensive large cone wheel and a small bevel gear driven by a shaft and a mounted on the housing, against said Pipe consists of a two-part bracket supported by two pipe clamps connected to the pipe ends, bifurcated Hebei, with the help of which an intermediate ring, frictionally connected to the large bevel gear, is attached to the two pipe ends to be welded or during the rotary movement caused by the shaft via the bevel gears. is pressed against the pipe to be welded and the counterpart and welded to them.



   The essential idea of the invention is therefore that an intermediate ring z. B. made of thermoplastic, which rests under pressure on the two pipe ends to be welded, is made to rotate. In doing so, it heats up together with the adjacent opposing surfaces to the heat of sweat. After cooling, the intermediate ring and pipe ends form a pressure-tight, homogeneous weld. This has the advantage over the previously known connections that work with metallic parts that it has the same corrosion resistance in all its parts as the pipes themselves, since the intermediate ring, fitting and pipes are made of the same material.



   The two pipe ends to be welded are held in place by a two-part holder, which advantageously partially surrounds the housing, by means of two pipe clips.



   To carry out the assembly, the housing and the large bevel gear are appropriately divided.



   The device is driven by a shaft via the bevel gears. This can be designed as a flexible shaft.



   In the figures, an expedient execution form of the device according to the invention is shown. Fig. 1 shows a longitudinal section, Fig. 2 shows a section rotated by 900 through the device in the axial direction.



   The device consists of a two-part housing 1 (FIG. 1) in which a small bevel gear 2 with a cylindrical shaft 3 is mounted by means of ball bearings 4 to 6. The two ball bearings 5 and 6 are separated from one another by a spacer sleeve 7 and held in place by the snap rings 8 and 9.



   The small bevel gear 2 engages in a two-part large bevel gear 10. This is held or stored in the housing 1 on two conical surfaces 11 and 12. With a third conical surface 13, the large bevel gear 10 engages a connecting piece 14. To increase the force transmitted in the conical surface 13, the surface 13 in the large bevel gear can be provided with drivers.



   A lever 15 is attached to the housing 1.



  It is pressed outwards by a spring 16.



  When actuated, it in turn presses with its front edge 17 against a metallic clamp 18 which is clamped around the pipe 19 to be welded. The second pipe end to be welded or the intermediate piece (fitting) 24 is attached to a two-part holder 20, which is hingedly mounted in the scissors 18, via a lower clamp 25 (FIG. 2).



   The bevel gears are driven via the cylindrical shaft 3 of the small bevel gear. For this purpose, a slot 26 is provided in the cylindrical shaft 3, into which a suitable head piece of a flexible shaft 21 engages. The flexible shaft is guided in a sleeve 22 which is connected to the housing 1 by means of a union nut r 23.



   During the welding, the conical intermediate ring 14 made of plastic, which rests on the conical surface 13 of the large bevel gear 10, is set in rotation by the flexible shaft 21 via the small bevel gear 2. By actuating the lever 15, the intermediate ring 14 is pressed axially into the intermediate piece 24 and against the tube 19. Here, the lever 15 is supported against the clamp 18 or against the intermediate piece 24 via the holder 20 and the lower clamp 25. The two parts to be welded, the tube 19 and the intermediate piece 24, are held in their position by the holder 20 or the clamps 18 and 25. After the connection has been welded and cooled, the clamps 18 and 25 are loosened; then the entire device, namely the two-part bevel gear 10, can be removed from the connection that has been created.
