Abstract

Hose of manual arc-welding and cutting torch has interchangeable connection to torch body by an arrangement of a connecting and sealing body (1) on the hose, with a sealing face (3) contg. several ring grooves. The connecting and sealing body (5) on the torch body has several sealing rings (4) on its end face which fit precisely between the grooves in the hose sealing face. The outside surface of the torch body is provided with a thread and the bodies can be screwed together using a union nut (2). A keyway may be provided in the torch connecting and sealing body, projecting to fit in bores in the hose connecting and sealing body.

Description

Die Erfindung bezieht sich auf die lösbare Verbindung zwischen dem Brennerrohr eines Lichtbogenhandschweiß- und Schneidbrenners und dem Brennergrundkörper, zumeist angeordnet im Handgriff mit den darin zugeführten Versorgungsleitungen für Strom, Wasser und Gas.The invention relates to the releasable connection between the Torch tube of a manual arc welding and cutting torch and the burner body, mostly arranged in the handle with the supply lines for electricity, water and gas supplied therein.

Die Unterbrechung der Versorgungsleitungen beim schweißnaht­ bedingten Wechsel des Brenners und damit Brennerrohres nimmt relativ viel Zeit in Anspruch. Außerdem gibt es Schweißpositionen, die beim Brennerwechsel beibehalten werden müssen. Bisher sind diesbezügliche Lösungen nicht bekannt.The interruption of the supply lines when welding conditional change of the burner and thus burner tube takes relatively long time. There are also welding positions which must be maintained when changing the burner. So far related solutions not known.

Bekannte Lösungen, wie DD 1 04 447, offenbaren dreh- und wechselbare Anschlußelemente, DE-PS 41 36 609 offenbart eine lösbare Verbindung für luftgekühlte Schweißbrenner, DE-PS 43 13 831 beschreibt eine Lösung, wie unterschiedliche Anschlußsysteme einfach und schnell maschinenseitig montiert werden können. Das einfache und sichere Wechseln des Brennerrohres während des Schweiß- bzw. Schneidvorganges bei wassergekühlten Lichtbogenhand­ schweiß- und Schneidbrennern auf der Griffseite ist ein noch ungelöstes Problem.Known solutions, such as DD 1 04 447, disclose rotary and changeable connection elements, DE-PS 41 36 609 discloses a Detachable connection for air-cooled welding torches, DE-PS 43 13 831 describes a solution like different connection systems can be easily and quickly installed on the machine side. The simple and safe changing of the burner tube during the Welding or cutting process with water-cooled arc hand welding and cutting torches on the handle side is still one unsolved problem.

Die Erfindung stellt sich daher die Aufgabe, das wechselbare Anschlußelement für wassergekühlte Lichtbogenhandschweiß- und Schneidbrenner dahingehend zu verbessern, daß der Brennerhals schnell und auch mit gleichbleibender Position gewechselt werden kann und die Wasserversorgungsleitungen während des Auswechselns beidseitig abgedichtet sind. The invention therefore has as its object the interchangeable Connection element for water-cooled manual arc welding and Cutting torch to improve the torch neck can be changed quickly and with the same position can and the water supply lines during the replacement are sealed on both sides.  

Erfindungsgemäß wird die bekannte Verbindung zwischen Brennerrohr und Brennergrundkörper unter Verwendung einer Überwurfmutter dahingehend verändert, daß am Brennerrohr und griffseitig am Brennergrundkörper Anschluß- und Dichtkörper festsitzend angeordnet sind, in denen wiederum Ringnuten bzw. Dichtringe angeordnet sind. Es sind mehrere Dichtringe so angeordnet, daß sie zwischen die Ringnuten des Anschluß- und Dichtkörpers am Brennerrohr genau passen. Beide Anschluß- und Dichtkörper sind an ihrer äußeren Oberfläche im Paßstellenbereich mit einem Gewinde ausgerüstet und dadurch mit der Überwurfmutter verschraubbar.According to the known connection between the burner tube and burner body using a union nut changed so that on the burner tube and handle side on Burner base body Connection and sealing body stuck are arranged, in which ring grooves or sealing rings are arranged. There are several sealing rings arranged so that they between the ring grooves of the connecting and sealing body on Fit the burner tube exactly. Both connection and sealing bodies are on their outer surface in the fitting area with a thread equipped and thus screwable with the union nut.

An Hand der Zeichnungen wird die erfindungsgemäße Lösung näher erläutert. Dabei zeigt Fig. 1 das Brennerrohr mit Gasdüse und der Kontaktstelle zum Brennergriff im Gebrauchszustand. Fig. 2 zeigt den in Fig. 1 markierten Bereich im Schnitt. Aus Fig. 2 ist zu erkennen, daß am Brennerrohr Anschluß- und Dichtkörper 1 angeordnet ist, der mit der Dichtfläche 3 zum Brennergrundkörper abschließt. In Dichtfläche 3 sind mehrere, nicht sichtbare Ringnuten eingearbeitet. Über Anschluß- und Dichtkörper 1 ist Überwurfmutter 2 gesteckt. Mit Brennergrundkörper ist Anschluß- und Dichtkörper 5 fest verbunden. Im Anschluß- und Dichtkörper 5 ist herausragend ein Key-Way 6 angeordnet, der in entsprechend große und tiefe Bohrungen des Anschluß- und Dichtkörpers 3 paßt. Stirnflächig sind auf Anschluß- und Dichtkörper 5 mehrere Dichtringe 4 angeordnet, die in ihrer Anzahl und Lage zwischen die Ringnuten in Dichtfläche 3 passen. Der Anschluß- und Dichtkörper 5 ist an seiner Außenfläche mit einem Gewinde versehen und so in Überwurfmutter 2 einschraubbar. The solution according to the invention is explained in more detail with reference to the drawings. Here, FIG. 1 shows the burner tube with gas nozzle and the contact point for the torch handle in use. Fig. 2 shows the area marked in Fig. 1 in section. From Fig. 2 it can be seen that connection and sealing body 1 is arranged on the burner tube, which ends with the sealing surface 3 to the burner main body. Several sealing grooves (not visible) are incorporated in sealing surface 3 . Union nut 2 is inserted over connection and sealing body 1 . Connection and sealing body 5 is firmly connected to the burner base body. A key-way 6 is outstandingly arranged in the connection and sealing body 5 and fits into correspondingly large and deep bores of the connection and sealing body 3 . On the end face, a plurality of sealing rings 4 are arranged on the connecting and sealing body 5 , the number and position of which fit between the ring grooves in the sealing surface 3 . The connection and sealing body 5 is provided on its outer surface with a thread and can thus be screwed into the union nut 2 .

Dichtringe 4 haben die Funktion der Wasserabdichtung zwischen den Ringnuten nach außen im geschlossenen Zustand. Mit der Anordnung der Anschluß- und Dichtkörper 1 am Brennerrohr und 5 am Brennergrundkörper eines Lichtbogenhandschweiß- und Schneidbrenners in der erfindungsgemäßen Ausgestaltung können Brennerrohre schnell und positionsgetreu ausgewechselt werden. Die Anordnung der Anschluß- und Dichtkörper 1 und 5 an die Brennerteile ist unkompliziert, die Variabilität der so ausgerüsteten wassergekühlten Lichtbogenhandschweiß- und Schneidbrenner ist groß und ihre Handhabung einfach und sicher.Sealing rings 4 have the function of waterproofing between the ring grooves to the outside in the closed state. With the arrangement of the connection and sealing bodies 1 on the torch tube and 5 on the torch base body of a manual arc welding and cutting torch in the embodiment according to the invention, torch tubes can be replaced quickly and in the correct position. The arrangement of the connecting and sealing bodies 1 and 5 on the torch parts is straightforward, the variability of the water-cooled manual arc welding and cutting torches equipped in this way is great and their handling is simple and safe.
