Description

Heißluftschweißvorrichtung für thermoplastische Kunststoffe ohne bzw. mit Schweißdrahtführung an einer Düse Die Erfindung betrifft eine Heißluftschweißvorrichtung für thermoplastische Kunststoffe ohne bzw. mit Schweißdrahtführung an einer Düse. Hot air welding device for thermoplastics without or with welding wire guide on a nozzle. The invention relates to a hot air welding device for thermoplastics with or without welding wire guide on a nozzle.

Die Verschweißung thermoplastischer Kunststoffe mit Hilfe von Heißluftschweißgeräten und unterschiedlich geformten Schweißdüsen ist bekannt. Die bisher am meisten verwendeten Runddüsen (B) bestehen aus einem abgebogenen Rohr mit verschieden großer Luftaustrittsöffnung. Bei Verwendung dieser Düsen zum Schweißen wird der Schweißdraht mit der einen Hand in die Kehle der zu verschweißenden Werkstücke gedrückt, und die Verschweißung des Schweißdrahtes mit dem Werkstück geschieht durch den aus der Düse austretenden heißen Luftstrahl. The welding of thermoplastics with the help of hot air welding devices and differently shaped welding nozzles are known. Most used so far Round nozzles (B) consist of a bent tube with an air outlet opening of different sizes. When using these nozzles for welding, the welding wire is with one hand pressed into the throat of the workpieces to be welded, and the welding of the Welding wire with the workpiece happens through the hot emerging from the nozzle Air jet.

Es sind auch Schweißdüsen im Gebrauch, bei denen der Schweißdraht durch ein Vorwärmröhrchen, das mit der Schweißdüse fest verbunden ist, geführt wird. There are also welding nozzles in use in which the welding wire is passed through a preheating tube that is firmly connected to the welding nozzle.

Bei Verwendung dieser Düse hat der Schweißer eine Hand frei, da der Schweißdraht selbsttätig nachläuft und der Schweißdruck auf den Schweißdraht durch den Gleitschuh der Schweißdüse von der Hand des Schweißers ausgeübt wird, die das Schweißgerät führt.When using this nozzle, the welder has one hand free as the The welding wire runs automatically and the welding pressure is applied to the welding wire the welding nozzle's sliding shoe is exercised by the welder's hand, which is the Welding machine leads.

Es werden auch Heftdüsen verwendet, mit denen zusammenzufügende Kunststoffteile im Grunde der Naht geheftet werden. Beim Heften tritt ein schmaler Heißluftstrahl aus der Unterseite der Düse, deren nachfolgende Spitze dann das plastifizierte Material der zusammenzufügenden Werkstücke durch leichten Druck miteinander verbindet. Auf diese Wurzelnaht können dann weitere Schweißdrähte mit rundem oder profiliertem Querschnitt eingeschweißt werden. Stapling nozzles are also used, with which plastic parts are to be joined basically the seam will be stapled. A narrow jet of hot air occurs when stapling from the bottom of the nozzle, whose subsequent tip then the plasticized material of the workpieces to be joined together by applying light pressure. on This root seam can then be further welded wires with round or profiled ones Cross-section to be welded.

In der Praxis der Verarbeitung von thermoplastischen Kunststoffen spielen sich die Arbeitsvorgänge meist so ab, daß die Werkstücke geheftet und anschließend endgültig verschweißt werden. Bei Serien-und auch bei Einzelfertigungen ist es deshalb notwendig, das Werkstück einmal zum Heften und zum endgültigen Verschweißen der Naht nochmals einzuspannen. Außerdem müssen hierfür gleichzeitig zwei komplette Schweißgeräte, eins zum Heften und eins zum Schweißen, dauernd in Betriebsbereitschaft sein. In the practice of processing thermoplastics the work processes are usually played in such a way that the workpieces are stapled and then be finally welded. That is why it is for series and also for one-off productions necessary, the workpiece once for stapling and for the final welding of the Clamp the seam again. In addition, two complete Welding devices, one for tacking and one for welding, always on standby be.

Um diese Mängel auszuschalten, wird erfindungsgemäß vorgeschlagen, daß an dem vorderen Ende der Düse eine Heftdüse schwenkbar angeordnet ist, so daß die Heißluft durch einen Schlitz der Heftdüse auf den thermoplastischen Kunststoff austreten kann. In order to eliminate these deficiencies, it is proposed according to the invention that that at the front end of the nozzle a stapling nozzle is pivotably arranged so that the hot air through a slot in the tacking nozzle onto the thermoplastic material can emerge.

Die Erfindung bezweckt die Rüstzeiten zu verkürzen und Energie zu sparen. The invention aims to shorten the set-up times and energy save.

Abb. 1 zeigt die Heftdüse S in Vorder- und Seitenansicht mit den Laschen I und den Befestigungslöchern d; Abb. 2 zeigt die Heftdüse S an einer bekannten Heißluftschweißvorrichtung B ohne Schweißdrahtführung in Arbeits- und Ruhestellung; Abb. 3 zeigt die Heftdüse S an einer bekannten Heißluftschweißvorrichtung C mit Schweißdrahtführung in Arbeits- und Ruhestellung. Fig. 1 shows the stapling nozzle S in front and side views with the Tabs I and the mounting holes d; Fig. 2 shows the staple nozzle S on a known one Hot air welding device B without welding wire guide in working and rest position; Fig. 3 shows the tacking nozzle S on a known hot air welding device C with Welding wire guide in working and rest position.

Mit Hilfe der Heftdüse S ist es also möglich, die Düsen B und C erst zum Heften und nach Umklappen der Heftdüse S anschließend zum Schweißen zu verwenden. With the help of the staple nozzle S it is possible to use the nozzles B and C first to be used for tacking and, after folding down the tacking nozzle S, then for welding.

Für diese beiden Arbeitsvorgänge ist jeweils nur ein Heißluftschweißgerät erforderlich, und die Rüstzeit wird um die Hälfte vermindert. There is only one hot air welding device for each of these two work processes required, and the set-up time is reduced by half.
