Gasdüse für Schutzgas-HandschweißbrennerGas nozzle for inert gas hand welding torch

Die Erfindung bezieht sich auf eine Gasdüse, wie sie in Schutzgas-Handschweißbrennern zum Einsatz kommt. Die Gasdüse ist über einen Gasdüsenträger mit dem Brennerhals des Schutzgas-Handschweißbrenners verbunden. Die Gasdüse ist bei bekannten Brennern über Steck- oder Schraubverbindungen am Gasdüsenträger angeordnet und dieser wiederum sitzt i.d.R. im Brennerhals.The invention relates to a gas nozzle as used in inert gas hand welding torches. The gas nozzle is connected to the torch neck of the inert gas hand welding torch via a gas nozzle carrier. In known torches, the gas nozzle is arranged on the gas nozzle carrier via plug or screw connections, and this in turn is usually located in the torch neck.

Die Gasdüse ist ein empfindliches Brennerteil, da sie einmal einer hohen thermischen Belastung und zum anderen Schweißspritzern direkt ausgesetzt ist. Das führt zu einem hohen Materialverschleiß und/oder zu häufigen Reinigungsarbeiten an der Gasdüse. Außerdem führt die hohe thermische Belastung der Gasdüse zur überhitzung des Brennerhalses und damit auch zu erschwerten Arbeitsbedingungen, denen der Schweißer, also die Arbeitskraft, ausgesetzt ist.The gas nozzle is a sensitive part of the torch because it is exposed to high thermal loads and to welding spatter. This leads to high material wear and/or frequent cleaning work on the gas nozzle. In addition, the high thermal load on the gas nozzle leads to overheating of the torch neck and thus to difficult working conditions to which the welder, i.e. the worker, is exposed.

Der Erfindung liegt daher die Aufgabe zugrunde, die Gasdüse so auszugestalten, daß eine größtmögliche Wärmeübertragung am Brennerkopf gewährleistet wird und damit auch eine schnelle Abkühlung, um einmal Überhitzung und Verschmutzung durch Schweißspritzern weitestgehend minimieren und zum anderen die Lebensdauer der Gasdüsen erhöhen zu können.The invention is therefore based on the object of designing the gas nozzle in such a way that the greatest possible heat transfer to the burner head is ensured and thus rapid cooling in order to minimize overheating and contamination by welding spatter as far as possible and to increase the service life of the gas nozzles.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen Gasdüse und Gasdüsenträger eine größtmögliche Wärmeübertragungsfläche geschaffen wird. Die Wärmeübertragungsfläche ist dabei so ausgebildet, daß das Zusammenfügen von Gasdüse mit Gasdüsenträger problemlos ist und ein
sicherer Halt zwischen Gasdüse und Gasdüsenträger gewährleistet wird. Dazu sind die Gasdüse und der Gasdüsenträger, wie aus der Zeichnung ersichtlich, besonders ausgebildet.This object is achieved according to the invention by creating the largest possible heat transfer surface between the gas nozzle and the gas nozzle carrier. The heat transfer surface is designed in such a way that the joining of the gas nozzle with the gas nozzle carrier is problem-free and a
A secure hold between the gas nozzle and the gas nozzle holder is ensured. The gas nozzle and the gas nozzle holder are specially designed for this purpose, as can be seen in the drawing.

Der am nicht dargestellten Brennerhals angesetzte Gasdüsenträger 2 ist mit einem Außengewinde A und im Anschluß daran mit Kontaktfläche 3 versehen.The gas nozzle carrier 2 attached to the burner neck (not shown) is provided with an external thread A and, in connection thereto, with a contact surface 3.

Dabei kann die Kontaktfläche 3 zylindrisch, wie dargestellt, oder konisch sein. Entsprechend hat Gasdüse 1, an dem der Gasdüsenspitze entgegengesetzten Ende, das passende Innengewinde 5 und im Anschluß einen zylindrischen oder konischen Abschnitt 6, der i.d.R. der Länge von Kontaktfläche 3 am Gasdüsenträger 2 entspricht. Der Gasdüsenträger 2 kann so über eine kombinierte Schraub-Steckverbindung sicher und fest mit der Gasdüse 1 verbunden werden und gewährleistet dabei eine maximale Wärmeübertragungsfläche, wie 10 zeigt. Zur Unterstützung der sicheren kombinierten Schraub-Steckverbindung zwischen Gasdüsenträger und Gasdüse sind erfindungsgemäß an der Gasdüsenoberfläche im Bereich des Innengewindes 5 Dehnungsfugen 7 angeordnet, die von Feder 8 mit Vorspannung umschlossen werden und so das Dehnungsverhalten der Gasdüse 1 während des Brennerbetriebes kompensieren.The contact surface 3 can be cylindrical, as shown, or conical. Accordingly, the gas nozzle 1 has the appropriate internal thread 5 at the end opposite the gas nozzle tip and a cylindrical or conical section 6, which usually corresponds to the length of the contact surface 3 on the gas nozzle carrier 2. The gas nozzle carrier 2 can thus be securely and firmly connected to the gas nozzle 1 via a combined screw-plug connection, thereby ensuring a maximum heat transfer surface, as shown in Figure 10. To support the secure combined screw-plug connection between the gas nozzle carrier and the gas nozzle, according to the invention, expansion joints 7 are arranged on the gas nozzle surface in the area of the internal thread 5, which are enclosed by a spring 8 with preload and thus compensate for the expansion behavior of the gas nozzle 1 during burner operation.
