Schweissmaschine zum maschinellen Zusammenschweissen von thermoplastischen KunststoffkörpernWelding machine for the mechanical welding together of thermoplastic plastic bodies

Die vorliegende Erfindung betrifft eine Schweissmaschine zum maschinellen Zusammenschweissen thermoplastischer Künststoff-Körper, mit kontinuierlich fortschreitender Relativbewegung zwischen diesen Körpern und der Schweissmaschine.The present invention relates to a welding machine for machine welding together of thermoplastic plastic bodies, with continuously progressing relative movement between these bodies and the welding machine.

Nach der bisher vielfach angewandten Methode zum Zusammenschweissen von thermoplastischen Kunststoffkörpern, insbesondere Rohren, wird ein Stumpfschweissvorgang gewählt, bei welchem die Körperz.B. die Rohrenden erhitzt und in achsialer Richtung zusammengepresst werden. Es ist ferner bekannt geworden, insbesondere Rohre grossen Durchmessers mit Hilfe einer V-Naht und einem Schweisskeil zu schweissen, was jedoch äusserst anstrengend und mühsam ist, so dass das Verlegen längerer Rohrstränge sehr arbeitsintensiv wird.According to the previously widely used method of welding together of thermoplastic plastic bodies, in particular pipes, a butt welding process is selected in which the bodies e.g. the pipe ends are heated and pressed together in the axial direction. It has also become known, in particular Large diameter pipes with the help of a V-seam and a Welding a welding wedge, which is extremely strenuous and laborious, so that the laying of longer pipe strings is very difficult becomes labor intensive.

Fig. 1 zeigt die Schweissmaschine, wie diese zum Verschweissen, insbesondere grossdurchmessriger thermoplastischer Kunststoffrohre, zum Einsatz gelangt. Zwei miteinander zu verschweissende Kunststoffrohre 1 und 4, deren Enden 2 und 5 V-förmig angeschrägt sind, werden bündig zusammengestossen. Pie die Schweissung durchführende Schweissmaschine 6 wird in entsprechender Lage auf die Rohre gesetzt und mittels zweier Kettenzüge 7 und 8 am Rohr derart befestigt, dass durch Ziehen an der Schweissmaschine 6 diese um das Rohr herum bewegt werden kann. Die Ketten 7 "und 8Fig. 1 shows the welding machine as it is used for welding, in particular large-diameter thermoplastic plastic pipes come into use. Two to be welded together Plastic pipes 1 and 4, the ends 2 and 5 of which are bevelled in a V-shape are butted together flush. The welding machine 6 performing the welding is opened in the appropriate position the pipes are set and fastened to the pipe by means of two chain hoists 7 and 8 in such a way that by pulling on the welding machine 6 this can be moved around the pipe. The chains 7 "and 8

sind durch Rollenpaare 10, welche sich über den Umfang der Ketten 7 und 8 ungefähr gleichmässig verteilen, gestützt. Die Achsen 11 der Rollenpaare 10 ragen seitlich über die Rollen heraus und dienen als Auflage, insbesondere für das Zugseil (nicht dargestellt) zum Bewegen der Schweissmaschine. Zwischen den sich folgenden Rollenpaaren 10 befindet sich jeweils eine Führungsrolle 14, welche dafür sorgt, dass sich die Kettenpaare 7*8 mit den Rollenpaaren 10 nicht in achsialer Richtung auf den Rohren verschieben.are by pairs of rollers 10, which extend over the circumference of the Distribute chains 7 and 8 approximately evenly, supported. The axes 11 of the pairs of rollers 10 protrude laterally over the rollers and serve as a support, in particular for the pull rope (not shown) for moving the welding machine. Between them following roller pairs 10 there is a guide roller 14 each, which ensures that the chain pairs 7 * 8 do not move with the pairs of rollers 10 in the axial direction on the tubes.

man vor der eigentlichen Schweissmaschine ein Vorwärmgerät zum Vorwärmen der Rohrenden einsetzt, welches direkt mittels einer besonderen Klemmvorrichtung auf dem Laufwagen 15 befestigt werden kann. Dem· gleichen Zwecke dient auch eine, gegebenenfalls, spezielle, Vorwärmung des Schweissdrahtes 65.a preheater is installed in front of the actual welding machine Preheating of the pipe ends begins, which are fastened directly to the carriage 15 by means of a special clamping device can. The same purpose also serves, if necessary, special, Preheating of the welding wire 65.

Es ist auch möglich, in diesem Sinne den Schweissdraht direkt vom Extruder über eine heizbare Spule oder auf einem beheizbaren Trägerband in den Schweissapparat zu führen. Das Vorheizen des Schweissdrahtes kann durch Direktkontakt mit aufgeheizten Teilen, beispielsweise einem aufgeheizten Trägerband, erfolgen. Dieses Trägerband kann gleichzeitig als Abzugsband für den Schweissdraht dienen, um ein Reissen des aufgeweichten Drahtes zu verhüten. Dieses Band kann anschliessend als fibdeckband für die warme Schweissnaht dienen. Dies bewirkt ein langsames, gleichmässiges, spannungsfreies Abkühlen der Schweissnaht. Es können natürlich auch die Schweissdrahtrollen als Ganzes vorgewärmt werden. Es ist ferner möglich, die Schweissmaschine stationär zu halten und das Schweissgut zu bewegen. Ausser V-Nähten können auch Bördelnähte von übereinander geschobenen Körpern oder andere Nahtarten mit dieser Maschine, stationär oder bewegt, geschweisst werden.In this sense, it is also possible to use the welding wire directly from the extruder via a heatable coil or on a heatable carrier tape into the welding machine. The preheating of the welding wire can be done by direct contact with heated parts, for example a heated carrier tape. This carrier tape can also be used as a pull-off tape for the welding wire serve to prevent the softened wire from breaking. This tape can then be used as a fiber cover tape for the warm weld seam to serve. This causes a slow, even, tension-free Cooling of the weld seam. Of course, the welding wire coils can also be preheated as a whole. It is further possible to keep the welding machine stationary and the weld metal to move. In addition to V-seams, flanged seams from one above the other can also be used pushed bodies or other types of seams can be welded with this machine, stationary or moving.
