Description
Sϊromόüse für Schweißbrenner Sϊromόüse for welding torch
Die Erfindung betrifft eine Stromdüse für Schweißbrenner mit einem geraden Drahtförderkanal zur Führung und Kontaktierung der Drahtelektrode.The invention relates to a Stromdüse for welding torch with a straight wire feed channel for guiding and contacting the wire electrode.
Die Stromdüse, auch Kontaktdüse genannt, hat einmal die Aufgabe, die Drahtelektrode zu führen und zum anderen den Strom in die Drahtelektrode in geringem Abstand vom Lichtbogen einzuleiten. Die Stromdüse ist weiter der störan-fälligste Teil im Schweißstromkreis und überwiegend brennerspezifisch verwendbar, d. h. jeder Schweißbrennerhersteller setzt in seinen Erzeugnissen speziell konstruierte Stromdüsen ein. Da in Unternehmen selten Schweißbrenner von nur einem Hersteller zum Einsatz kommen, ist die Bevorratung mit Ersatzteilen aufwendig.The Stromdüse, also called contact nozzle, once has the task of guiding the wire electrode and on the other to initiate the current in the wire electrode at a small distance from the arc. The Stromdüse is still the most troublesome part in the welding circuit and mainly burner-specific usable, d. H. Every manufacturer of welding torches uses specially designed current nozzles in its products. Since welding torches from only one manufacturer are rarely used in companies, the stocking of spare parts is complex.
Vor diesem technischen Hintergrund stellt sich die Erfindung die Aufgabe, eine Stromdüse zu entwickeln, die in Schweißbrenner, insbesondere aller bekannten Hersteller, passt.Against this technical background, the invention has the object to develop a Stromdüse that fits in welding torch, in particular of all known manufacturers.
Erfindungsgemäß, wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.According to the invention, the object is solved by the features of claim 1. Advantageous developments emerge from the dependent claims.
Eine erfindungsgemäße Stromdüse für Schweißbrenner mit einem geraden Drahtförderkanal weist auf, dass die Stromdüse (1) mindestens zweiteilig ausgebildet ist, wobei die Stromdüsenspitze (2) mit dem verbleibenden Adapterstück (3) lösbar verbunden ist und das Adapterstück (3) wiederum lösbar mit dem Düsenstock verbunden ist.A current nozzle for welding torch with a straight wire feed channel according to the invention comprises that the current nozzle (1) is formed at least in two parts, wherein the current nozzle tip (2) with the remaining adapter piece (3) is detachably connected and the adapter piece (3) in turn releasably connected to the nozzle connected is.
Bevorzugt ist bei der Stromdüse der Durchmesser der Bohrung (4) in der Stromdüsenspitze (2) kleiner ist als im Adapterstück und beide Bohrungen (4, 5) sind brennerseitig mit E/πführschrägen ausgebildet.In the case of the flow nozzle, the diameter of the bore (4) in the flow nozzle tip (2) is preferably smaller than in the adapter piece, and both bores (4, 5) are designed with E / π guiding bevels on the burner side.
Es kann vorteilhaft sein, dass die lösbare Verbindung zwischen Stromdüsenspitze (2) und Adapterstück (3) eine Schraubverbindung ist.It may be advantageous that the detachable connection between the current nozzle tip (2) and adapter piece (3) is a screw connection.
Günstigerweise ist die Stromdüse aus Kupferlegierungen hergestellt, wobei zumindest die Stromdüsenspitze aus dispersionsgehärtetem Kupfer besteht. Vorte/Jhafterweise besteht die Stromdüsenspitze (2) aus einem Werkstoffverbund mit einem verschleißfesten Kern aus dispersionsgehärtetem Kupfer und einer Hülle aus einer gut leitenden KupferlegieruπgConveniently, the current nozzle is made of copper alloys, wherein at least the current nozzle tip consists of dispersion-hardened copper. Vorte / Jhafterweise the Stromdüsenspitze (2) consists of a composite material with a wear-resistant core of dispersion-hardened copper and a shell of a highly conductive Kupferlegieruπg
Es kann auch günstig sein, dass die-Stromdüsenspitze (2) aus einem Werkstoffverbund besteht, mit einem verschleißfesten Kern aus dispersionsgehärtetem Kupfer und einer Hülle aus Reinkupfer.It may also be favorable that the-current nozzle tip (2) consists of a composite material, with a wear-resistant core of dispersion-hardened copper and a shell of pure copper.
Bei einer Ausführungsform ist das dispersionsverfestigte Material im Kern der Strom-düsenspitze (2) partikelverstärkt.In one embodiment, the dispersion strengthened material is particle-reinforced in the core of the stream nozzle tip (2).
So kann die Partikelverstärkung mit verschleißfesten Partikeln, ausgewählt aus der Gruppe bestehend aus Bor, Hartstoffpartikeln, WC, W, TiB2, SiC, TiC1 AI2O3, ZrO2, TiO2, SiO2, SiC, TiN, Siliciumnitrid sowie Kombinationen derselben, durchgeführt sein.Thus, the particle reinforcement with wear-resistant particles selected from the group consisting of boron, hard material particles, WC, W, TiB2, SiC, TiC 1 Al2O3, ZrO2, TiO2, SiO2, SiC, TiN, silicon nitride and combinations thereof, be performed.
Die Stromdüse ist bevorzugt mehrteilig - bspw. zweiteilig - ausgebildet und zwar so, dass die Trennung unmittelbar nach der Stromdüsenspitze erfolgt. Es entsteht so ein Adapterstück. Beide Konstruktionsteile sind lösbar miteinander verbunden, bevorzugt miteinander verschraubt. Das hat einmal den Vorteil, dass im Bedarfsfall nur die verschlissene Stromdüsenspitze gewechselt wird und nicht die gesamte Stromdüse ausgetauscht werden muss. Weitere Vorteile sind die einfachere und platzsparendere Lagerhaltung sowie Kosteneinsparung im Materialeinkauf, weil das störanfällige Teil die Stromdüsenspitze ist und nicht die gesamte Stromdüse. Darüber hinaus dient diese Konstruktion durch Schonung von Ressourcen auch dem Umweltschutz und der Zielsetzung für nachhaltiges Wirtschaften. Das Adapterstück ist brennerseitig so ausgebildet, dass sowohl der Durchmesser als auch die Gewindegeometrie am brennerseitigen Ende des Adapters der Geometrie des Gasdüsenstockes des gewählten Schweißbrenners angepasst ist. Die Adapter sind brennerspezifisch ausgeführt.The Stromdüse is preferably in several parts - eg. In two parts - designed in such a way that the separation takes place immediately after the current nozzle tip. This creates an adapter piece. Both structural parts are releasably connected to each other, preferably screwed together. This has the advantage that only the worn current nozzle tip is replaced if necessary and not the entire current nozzle must be replaced. Further advantages are the simpler and more space-saving storage and cost savings in material purchasing, because the trouble-prone part is the current nozzle tip and not the entire Stromdüse. In addition, by conserving resources, this construction also serves environmental protection and the objective of sustainable management. The adapter piece is burner-side designed so that both the diameter and the thread geometry is adapted to the burner-side end of the adapter of the geometry of the gas nozzle stick of the selected welding torch. The adapters are burner-specific.
Die Erfindung wird nachfolgend anhand der Zeichnungen einer bevorzugten Ausführungsform der Erfindung, auf weiche sie keineswegs eingeschränkt ist, näher erläutert. Dabei zeigen: Fig. 1 Stromdüse, SchnittdarstellungThe invention will be explained in more detail below with reference to the drawings of a preferred embodiment of the invention, to which it is by no means restricted. Showing: Fig. 1 Stromdüse, sectional view

Fig. 4 Beispiele für zweiteiligen StromdüsenaufbauFig. 4 examples of two-part Stromdüsenaufbau
Fig. 1 zeigt die Stromdüse 1 in der montierten Form. Gut erkennbar ist der wesentlich kleinere Durchmesser der Bohrung 4 in der Stromdüsenspitze 2 im Vergleich zur Bohrung 5 im Adapter 3.Fig. 1 shows the current nozzle 1 in the assembled form. Clearly visible is the much smaller diameter of the bore 4 in the current nozzle tip 2 in comparison to the bore 5 in the adapter. 3
Wesentlich für die Erfindung ist auch die Ausbildung von Bohrung 4 und 5 mit einer Einführschräge, die jeweils brennerseitig angeordnet ist und die Genauigkeit der Drahtführung vom nichtdargestellten Brennerrohr in die Stromdüse 1 am Adapter 3 und an der Stromdüsenspitze 2 garantiert. Die Einlaufschräge an der Stromdüsenspitze 2 in Verbindung mit dem kleineren Durchmesser von Bohrung 4 bewirkt, dass nur in der Stromdüsenspitze 2 der Stromübergang auf den Schweißdraht erfolgt, das unerwünschte Wandern des Kontaktpunktes wird also stark ein-geschränkt. Gleichzeitig erhöht sich dadurch die Belastung für die Stromdüsenspitze 2 was erfindungsgemäß durch den Einsatz von verschleißbeständigerem Mate-rial, wie z.B. ODS-Kupfer, Verbundmaterial mit ODS-Kupfer im Kern oder auch ODS-Kupfer mit zusätzlicher Partikelverstärkung, gelöst wird. (s. Fig. 4:welche jeweils eine Originaldüse zeigt, wobei - von oben nach unten - die Adapterdüse zunächst auseinandergebaut und zerlegt sowie zusammengeschraubt, gezeigt ist).Essential for the invention is the formation of bore 4 and 5 with an insertion bevel, which is respectively arranged on the burner side and guarantees the accuracy of the wire guide from the unillustrated burner tube in the Stromdüse 1 on the adapter 3 and the Stromdüsenspitze 2. The inlet slope at the current nozzle tip 2 in conjunction with the smaller diameter of bore 4 causes only in the current nozzle tip 2, the current transfer occurs on the welding wire, the unwanted migration of the contact point is thus greatly restricted. At the same time thereby increases the burden on the Stromdüsenspitze 2 which according to the invention by the use of more wear-resistant mate rial, such. ODS copper, composite material with ODS copper in the core or ODS copper with additional particle reinforcement, is dissolved. (see Fig. 4: each showing an original nozzle, wherein - from top to bottom - the adapter nozzle first disassembled and disassembled and screwed together, is shown).
Die Stromdüsenspitze 2 ist mittels Schraubverbindung mit dem Adapter 3 lösbar und sicher verbunden. Adapter 3 ist brennerseitig mit einem Außengewinde 7 ausgerüstet, wobei die Rohrstärke von Adapter 3 am brennerseitigen Ende in Abhängigkeit vom verwendeten Fabrikat des Schweißbrenners variiert und speziell angepasst wird. Die Außenkontur der Stromdüse 1 bleibt dabei als Einheit erhalten, d. h. der Verbindungsbereich Stromdüsenspitze-Adapter ist stufenlos. Der größere Durchmesser von Bohrung 5 bewirkt, dass der Schweißdraht annähernd reibυngs- frei transportiert werden kann und an der Schweißbrennerspitze im Bereich des Lichtbogens kontinuierlich zur Verfügung Stent. iNeoen αer iviaxeπaieiπsμaiuny, υα jeweils nur die verschlissene Stromdüsenspitze 2 ausgetauscht werden muss, gestaltet sich mit der Stromdüse 1 nach der Erfindung auch die Lagerhaltung ökonomischer. Durch diese Kosteneinsparung im Materialeinkauf wird der Einsatz eines höherwertigeren, jedoch teureren Materials interessant.The current nozzle tip 2 is detachably and securely connected by means of screw connection with the adapter 3. Adapter 3 is equipped on the burner side with an external thread 7, wherein the tube thickness of adapter 3 at the burner end depending on the make of the welding torch used varies and is specially adapted. The outer contour of the Stromdüse 1 remains as a unit, ie the connection area Stromdüsenspitze adapter is infinitely variable. The larger diameter of bore 5 makes it possible to transport the welding wire approximately free of friction and at the tip of the welding torch in the region of the welding torch Arc continuously available stent. In each case only the worn current nozzle tip 2 has to be exchanged, with the current nozzle 1 according to the invention it also becomes more economically viable. This cost saving in material purchasing makes the use of a higher quality but more expensive material interesting.
Bevorzugt ist die Stromkontaktdüse aus einem Werkstoff-Verbund hergestellt, wobei mindestens der Kern der Düse aus dispersionsgehärtetem Kupfer besteht. Die Düsenbohrung erhält dadurch eine verschleißfestere Drahtführung.Preferably, the current contact nozzle is made of a composite material, wherein at least the core of the nozzle consists of dispersion-hardened copper. The nozzle bore thus receives a more wear-resistant wire guide.
Die verschleissfeste Drahtführung durch den dispersionsverfestigten Kern bewirkt eine exakte Führung des Schweissdrahtes und verhindert weitgehend das Auftreten von Drahtrückbrennern. Die Verschletfibeständigkeit kann durch die Einlagerung von Hartstoffpartikeln in das dispersionsverfestigte Material weiter verbessert werden.The wear-resistant wire guide through the dispersion-strengthened core causes an exact guidance of the welding wire and largely prevents the occurrence of wire return burners. The entanglement resistance can be further improved by incorporating hard material particles into the dispersion strengthened material.
Während eine bevorzugte Ausführungsform der Erfindung ausführlich beschrieben wurde, ist dem Fachmann, an den sich die Beschreibung wendet, offensichtlich, dass verschiedene alternative Vorgehensweisen und Ausführungsformen der Erfindung möglich sind, wie durch die Ansprüche definiert. While a preferred embodiment of the invention has been described in detail, it will be apparent to those skilled in the art to which this description appeals that various alternative approaches and embodiments of the invention are possible as defined by the claims.
