Description

Unser Zeichen: G.M. 467 Ti/Sl Ludwigshafen am Rein, den 16 801961 Vorrichtung zum Verschweißen von Kunststoffrohren Es ist bekannt Rohre aus thermoplastischen Kunststoffen durch Reibungsschweißen 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.Our reference: G.M. 467 Ti / Sl Ludwigshafen am Rein, 16 801961 Device for welding plastic pipes It is known pipes made of thermoplastic To join plastics by friction welding. This method is z. B. used to weld crimp rings or fixed flanges to pipe ends. The used However, devices have the disadvantage that they are only used in the workshop can.

An Montagestellen und zwar besonders zur Verbindung bereits verlegter Rohre sind sie nicht zu gebrauchen.At assembly points, especially to connect those that have already been laid They are of no use to pipes.

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.The device according to the invention is intended to solve the stated problem Avoid disadvantages. With it, plastic pipes should be placed anywhere, i. H. in the workshop or at the assembly site quickly and safely thanks to friction welding get connected.

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 Kegelrad 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 Hebel 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.This is achieved with a device that consists of a housing, a in the housing mounted angular drive with a two-part, one of the to Welding tubes comprising large bevel gear and one driven by a shaft small bevel gear as well as from a mounted on the housing, against the said tube via a two-part, through two pipe clamps with the pipe ends connected bracket is supported, forked lever, with the help of which a with the large bevel gear frictionally connected intermediate ring during the rotary movement caused by the shaft via the bevel gears to the two welded pipe ends or on the pipe to be welded as well as on the counterpart is pressed and welded to them.

Der wesentliche Erfindungsgedanke besteht demnach darin, daß ein Zwischenring aus thermoplastischem 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. The essential idea of the invention is therefore that a Intermediate ring made of thermoplastic material, which is to be welded on the two Pipe ends is applied under pressure, is made to rotate. He warms up in the process together with the adjacent mating surfaces on welding heat. Form after cooling Intermediate ring and pipe ends a pressure-tight, homogeneous weld. This has opposite the previously known compounds that work with metallic parts have the advantage, that it has the same corrosion resistance as the pipes in all of its parts even, since the intermediate ring, valve and pipes are made of the same material.

Die beiden zu verschweißenden Rohrenden werden durch eine zweiteilige Halterung, welche das Gehäuse teilweise umgibt, mittels zweier Rohrschellen festgehalten. The two pipe ends to be welded are replaced by a two-part Bracket, which partially surrounds the housing, held by means of two pipe clamps.

Zur Durchführung der Montage sind Gehäuse und großes Kegelrad geteilt. The housing and large bevel gear are divided to carry out the assembly.

Die Vorrichtung wird über die Kegelräder durch eine Welle augen trieben. Diese kann als biegsame Welle ausgeführt werden.The device is driven over the bevel gears by a shaft eyes. This can be designed as a flexible shaft.

Figur 1 zeigt einen Längsschnitt, Figur 2 einen hierzu um 900 gedrehten Schnitt durch die Vorrichtung in achsialer Richtung.In the figures is an expedient embodiment of the invention Device shown. FIG. 1 shows a longitudinal section, and FIG. 2 shows one for this Section through the device rotated by 900 in the axial direction.

Die Vorrichtung besteht aus einem zweiteiligen Gehäuse 1 (Figur 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.The device consists of a two-part housing 1 (Figure 1), in which a small bevel gear 2 with a cylindrical shaft 3 by means of the ball bearings 4 to 6 is stored. The two ball bearings 5 and 6 are supported by a spacer sleeve 7 separated from each other and held in place by the snap rings 8 and 9.

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 Kegelfläche 13 übertragenen Kraft kann die Fläche 13 im großen Kegelrad mit Mitnehmern versehen sein.The small bevel gear 2 engages in a two-part large bevel gear 10 a. This is held on two conical surfaces 11 and 12 in the housing 1 or stored. 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 be provided with drivers in the large bevel gear.

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 Schelle18, 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 Schelle 18 gelagert ist, über eine untere sichelle 25 befestigt (Figur 2).A lever 15 is attached to the housing 1. He is made by a feather 16 pushed outwards. When actuated, he in turn pushes with his front Edge 17 against a metallic clamp 18, which around the pipe to be welded 19 is clamped. The second pipe end to be welded or the intermediate piece (fitting 24 is provided with a two-part bracket 20, which articulated in the clamp 18 is mounted, attached via a lower sickle 25 (Figure 2).
