Abstract

Die Erfindung betrifft eine Gleitschweißdüse für Heißgasschweißgeräte, mit der in unterschiedlichen Arbeitspositionen die Plastmaterialien geheftet oder geschweißt werden können. Erfindungsgemäß wird das dadurch erreicht, daß ein Düsenkörper auf die vorhandene Runddüse des Heißgasschweißbrenners drehbar in Passung gesteckt ist, daß der Düsenkörper ausreichende Befestigung für den Arbeitsgang bietet.The invention relates to a Gleitschweißdüse for hot gas welding equipment, with the plastic materials can be stapled or welded in different working positions. According to the invention this is achieved in that a nozzle body is rotatably fitted into the existing round nozzle of the hot gas welding torch in fit that the nozzle body provides sufficient attachment for the operation.

Description

Gleitschweißdüse für Heißgasschweißgeräte AnwendungsgebietGleitschweißdüse for hot gas welding equipment Application

Die Erfindung betrifft eine Gleitschweißdüse für Heißgasschweißgeräte, insbesondere zum Heften und Schweißen von Thermoplaststoffen·The invention relates to a Gleitschweißdüse for hot gas welding equipment, in particular for stapling and welding of thermoplastics ·

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Es ist ganz allgemein bekannt, daß beim Heißgasschweißen der erzeugte Gasstrom auf Grund- und Zusatzmaterial gelenkt und im teigigen Zustand unter Druck verbunden wird. Es sind heißgasbetriebene Gleit- oder Schnellschweißdüsen bekannt, DD-PS 129 757, die den Schweißprozeß beschleunigen, aber meist nur eine Einzweckfunktion erfüllen* Dies erfolgt dadurch, daß ein Führungsrohr von der Vorwärmkammer umgeben ist,wobei die Austrittsöffnung des Führungsrohres in der Vorwärmkammer endet und mit dem Gasauslaß in Verbindung steht. Das Heißgas wird hierbei über ein Luftführungsrohr, das fest mit der Vorwärmkammer verbunden ist", auf das Grund- und Zusatzmaterial gelenkt und im teigigen Zustand von der Düsennase unter Druck verbunden.. Nachteilig ist, daß durch die starre Verbindung derHeißgaszuführung die Bewegungsrichtung beim Heften oder Schweißen immer in Längsachse des Gerätes erfolgen muß. Sind innerhalb eines Bauteiles Verbindungen herzustellen, bei denen die funktionsbedingte Baulänge.des Heißgasgerätes hinderlich ist, muß eine Düse mit gebogenem Zufall rungs rohr aufgeschraubt werden« Aus diesem Grund müssen mehrere Düsen vorrätig sein,It is well known that in hot gas welding the generated gas flow is directed to base and additional material and connected in the doughy state under pressure. There are hot gas operated sliding or Schnellschweißdüsen known, DD-PS 129 757, which accelerate the welding process, but usually only meet a Einzweckfunktion * This is done by a guide tube is surrounded by the preheating, wherein the outlet opening of the guide tube ends in the preheating and communicates with the gas outlet. The hot gas is in this case via an air guide tube, which is firmly connected to the preheating chamber, "directed to the base and additional material and connected in the doughy state of the nozzle nose under pressure .. The disadvantage is that the direction of movement when stapling or. By the rigid connection of the hot gas If there are connections within a component in which the function-related construction length of the hot gas device is a hindrance, a nozzle with a bent random pipe must be screwed on "For this reason, several nozzles must be in stock,

um den gleichen Zusatzwerkstoff an allen Stellen ordnungs» gemäß zu verschweißen· Weiterhin ist es nachteilig, daß für das'Heftschweißen zusätzlich besonders geformte Düsen erforderlich sind, mit denen der gezielt geleitete Heißgas-· strom das Grundmaterial aufteigen soll und die Düsenspitze' unter Druck die Materialien verbindet. Durch eine Schraubverbindung oder eine ausklappbare Anordnung sind die Düsen am Heißgasschweißbrenner befestigt· Auch hier müssen mehrere Düsen vorhanden sein, um in den unterschiedlichen Schweißpositionen arbeiten zu können» Dadurch bedingt, macht ein hoher Aufwand an Düsen und Zeit für diese Arbeitsweiss das Wechseln der Schraubverbindungen, die bei 38O0C leicht verzundern, erforderlich·Furthermore, it is disadvantageous that additionally specially shaped nozzles are required for tack welding with which the specifically directed hot gas stream is intended to rise the base material and the nozzle tip under pressure Materials connects. The nozzles are attached to the hot-gas welding torch by means of a screw connection or a fold-out arrangement. Again, several nozzles have to be present in order to be able to work in the different welding positions. In this way, a high expenditure of nozzles and time for this work white makes it necessary to change the screw connections. which easily scale up at 38O 0 C, required ·

Ziel der ErfindungObject of the invention

Das Ziel der Erfindung besteht darin, in Vermeidung der voranbeschriebenen Mangel, die Einsatzmöglichkeit von Gleitschweißdüsen zu erweitern und die Arbeitsproduktivität beim Plastschweißen zu erhöhen»The aim of the invention is, in avoiding the above-described defect, to expand the possibility of use of Gleitschweißdüsen and increase labor productivity in plastic welding »

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

Es besteht daher die Aufgabe, eine Gleitschweißdüse zu schaffen, die einfach gestaltet, ein Arbeiten in allen Schweißpositionen gestattet, ohne zusätzliche Schweißdüsen oder andere Hilfsmittel zu benötigen* Zur Lösung der Aufgabe wurde eine Gleitschweißdüse gefunden, die dadurch gekennzeichnet ist, daß ein Düsenkörper auf die vorhandene Runddüse des Heißgasschweißbrenners drehbar in Passung gesteckt ist, daß der schalenartig ausgebildete und am hinteren Teil mit einem Schlitz versehene Düsenkörper ausreichende Befestigung für den Arbeitsgang bietet*It is therefore an object to provide a Gleitschweißdüse, which allows simple design, working in all welding positions, without requiring additional welding nozzles or other aids * existing round nozzle of the hot gas welding torch is rotatably fitted in fit, that the cup-shaped and provided at the rear with a slot nozzle body provides sufficient attachment for the operation *
