Abstract
Description
Die Erfindung betrifft einen Brenner für Schutzgas-Lichtbogenschweißung mit einem Brennerkopf, von dem ein metallischer Stutzen als Gas- und Stromleitung ausgeht, der zumindest teilweise von einer Schutzhülse abgedeckt ist, und mit einem Brennergriff, der ein mit dem Stutzen kuppelbares metallisches Anschlußstück für Gas und Strom aufweist.The The invention relates to a burner for inert gas arc welding with a burner head, of which a metallic nozzle as a gas and Power line goes out, at least partially covered by a protective sleeve is, and with a burner handle, which can be coupled with the neck metallic Fitting for gas and Having electricity.
Ein
derartiger Brenner ist bekannt (
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Brenner der eingangs beschriebenen Gattung konstruktiv und montagetechnisch zu vereinfachen.In contrast, lies The invention is based on the object, a burner of the type described above To simplify the type of construction and assembly technology.
Diese Aufgabe wird dadurch gelöst, daß das Anschlußstück eine Bohrung aufweist, deren Innendurchmesser mit enger Passung dem Außendurchmesser des Stutzens entspricht, und daß der Außenumfang des Anschlußstückes im Bereich des dem Brennerkopf zugewandten Endes eine Haltenut aufweist, wobei die Schutzhülse an ihrem freien Ende innenseitig einen Haltering aufweist, der in die Haltenut eingreift, wenn Brennerkopf und Brennergriff vollständig miteinander verbunden sind.These Task is solved by that the fitting a Has bore whose inner diameter with a close fit to the outer diameter corresponds to the neck, and that the outer periphery of the fitting in the Area of the burner head end facing has a retaining groove, the protective sleeve has at its free end on the inside a retaining ring which in the retaining groove engages when burner head and torch handle completely together are connected.
Die Bearbeitung des Stutzens und des Anschlußstückes ist einfach, denn es handelt sich um Drehteile, die sich auch auf einfache Weise zusammenfügen lassen. Am Ende der Montage schnappt der Haltering der Schutzhülse in die Haltenut des Anschlußstückes, denn die Schutzhülse besteht in der Regel aus einem nachgiebigem Material, z.B. aus einem hitzebeständigen Silikon-Werkstoff. Die enge Passung zwischen dem Stutzen und der Bohrung gewährleistet hinreichende Sicherung für die Stromübertragung und auch für Gasdichtigkeit sowie eine hinreichende Wärmeübertragung zwischen Brennerkopf und Brennergriff. Das gilt insbesondere für wassergekühlte Brenner, bei denen auf eine Wasserkühlung des Brennerkopfes verzichtet werden kann.The Working the neck and fitting is easy, for it is about These are turned parts that can be put together in a simple way. At the end of the assembly, the retaining ring of the protective sleeve snaps into the Holding the connector, for the protective sleeve is usually made of a resilient material, e.g. from a heat-resistant Silicone material. The tight fit between the neck and the Drilled hole guaranteed adequate fuse for the power transmission and also for Gas tightness and adequate heat transfer between the burner head and burner handle. This is especially true for water-cooled burners, where on a water cooling the burner head can be dispensed with.
Um den Kontakt zwischen dem Stutzen und der Bohrung im Anschlußstück zu verbessern, kann es zweckmäßig sein, wenn der Stutzen wenigstens einen von seinem freien Ende ausgehenden Axialschlitz aufweist, dessen Länge kleiner ist als die Länge des in die Bohrung eingesteckten Stutzenabschnitts. Dann kann nämlich der geschlitzte Stutzenabschnitt gegen die Wandung der Bohrung federn.Around to improve the contact between the neck and the bore in the fitting, it may be appropriate if the neck at least one emanating from its free end Axial slot has, whose length is smaller than the length of the nozzle section inserted into the bore. Then, namely, the Slotted socket section against the wall of the bore springs.
Es besteht auch die Möglichkeit, in das Anschlußstück eine Hülse einzusetzen, die die Bohrung aufweist. Auch diese Hülse kann wenigstens einen Axialschlitz aufweisen, der von dem dem Brennerkopf zugewandten Ende ausgeht, wodurch im Ergebnis die federnde Anlage zwischen Stutzen und Bohrung unterstützt wird.It there is also the possibility in the fitting one Insert sleeve, which has the bore. This sleeve can also have at least one axial slot have, which emanates from the end facing the burner head, resulting in the resilient system between nozzle and bore supports becomes.
Handelt es sich um einen wassergekühlten Brenner, dann kann ein Ringraum mit Kühlwasseranschlüssen zwischen dem Anschlußstück und der Hülse vorgesehen sein. Die Kühlwasseranschlüsse münden vorzugsweise stirnseitig in den Ringraum. Wie bereits erwähnt genügt es, das Anschlußstück mit der Hülse zu kühlen, weil für die Wärmeübertragung zwischen Brennerkopf und Brennergriff die Kontaktfläche zwischen Stutzen und Bohrung ausreicht.These it is a water-cooled burner, then an annulus with cooling water connections between the connector and the Sleeve provided be. The cooling water connections preferably open frontally into the annulus. As already mentioned, it is sufficient, the fitting with the Sleeve too cool, because for the heat transfer between the burner head and torch handle the contact surface between Socket and bore sufficient.
