Abstract
Description
Die Erfindung betrifft einen Schneidbrenner mit einem Brennerkopf, der eine auswechselbare Schneiddüse aufnimmt, nach dem Oberbegriff des Anspruchs 1.The invention relates to a cutting torch with a burner head, which accommodates an exchangeable cutting nozzle, according to the preamble of
Bei einem bekannten Schneidbrenner mit einteiliger, gasemischender Düse ist eine Brennerspitze von einer Hülse umgeben. Diese beiden Teile sind mittels eines feingängigen Gewindes fest miteinander verbunden und gegeneinander abgedichtet (
Um einen leichteren Düsenwechsel insbesondere der Schneiddüse zu ermöglichen, ist es bereits bekannt, eine Schneiddüsenaufnahme, in welche die Schneiddüse hineinragt, mit einer ringspaltförmigen Heizdüsenaufnahme koaxial zu umgeben und in diese Heizdüsenaufnahme die Heizdüse einzusetzen (
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Schneidbrenner nach dem Oberbegriff des Anspruchs 1 bereitzustellen, bei dem der Düsenwechsel mit unkomplizierten technischen Mitteln schneller handhabbar und trotzdem zuverlässig ist.The present invention is therefore an object of the invention to provide a cutting torch according to the preamble of
Hierzu weist der erfindungsgemäße Schneidbrenner die Kombination der in Anspruch 1 angegebenen Merkmale auf. Das Merkmal der kappenartigen Heizdüse ist in Anspruch 2 konkretisiert.For this purpose, the cutting torch according to the invention has the combination of the features specified in
Eine vorteilhafte Variante der kappenartigen Heizdüsenanordnung ist in Anspruch 3 angegeben.An advantageous variant of the cap-like Heizdüsenanordnung is specified in
In jedem der beiden obigen Fälle ist ein Düsenschnellwechselsystem geschaffen, welches einen Wechsel der Schneiddüse und der Heizdüse an dem Brennerkopf ohne Werkzeug besonders rasch ermöglicht. Der Düsenwechsel kann damit rationell automatisiert werden.In each of the two above cases, a nozzle quick change system is provided which allows a change of the cutting nozzle and the heating nozzle on the burner head without tools very quickly. The nozzle change can thus be efficiently automated.
Die im Betrieb des Schneidbrenners erforderliche Anpresskraft der Heizdüse an den Brennerkopf wird zweckmäßig durch die Flächenpressung eines O-Rings in vertikaler Richtung gemäß Anspruch 1 realisiert, indem ein unterer Außenmantelabschnitt des Brennerkopfs eine erste ringförmige Auflagefläche aufweist und ein oberer Abschnitt der kappenartigen Heizdüse eine nach innen vorstehende zweite ringförmige Auflagefläche hat, welche der ersten ringförmigen Auflagefläche gegenüberliegt, wobei ein O-Ring zwischen der ersten ringförmigen Auflagefläche und der zweiten ringförmigen Auflagefläche angeordnet ist. Diese gewindelose Abdichtung ist für den automatisierten Düsenwechsel günstig. Mit dieser Abdichtung sowie der Anordnung der Verbindungselemente des Schnellverschlusses in der kappenartigen Heizdüsenanordnung werden die Verbindungselemente vor mechanischer Beschädigung und Verschmutzung geschützt.The required during operation of the cutting torch contact pressure of the heating nozzle to the burner head is expediently realized by the surface pressure of an O-ring in the vertical direction according to
Der zum Düsenwechsel vorgesehene Schnellverschluss kann in einer ersten Ausführungsform gemäß Anspruch 4 durch wenigstens einen Passstift realisiert sein, der aus einem unteren Außenmantelabschnitt des Brennerkopfs herausragt, und durch wenigstens eine Bajonettnut in dem oberen Abschnitt der kappenartigen Heizdüse bzw. der Außenkappe, in welche Bajonettnut der Passstift eingreift.The provided for changing the nozzle quick release can be realized in a first embodiment according to claim 4 by at least one dowel pin protruding from a lower outer shell portion of the burner head, and by at least one bayonet groove in the upper portion of the cap-like heating nozzle or the outer cap, in which bayonet the Engaging pin engages.
In einer zweiten Ausführungsform des Schnellverschlusses wird eine besonders zuverlässige Verbindung der Heizdüse und der Schneiddüse mit dem Brennerkopf gemäß Anspruch 5 dadurch realisiert, dass aus dem unteren Außenmantelabschnitt des Brennerkopfs zwei Passstifte außen diametral gegenüberliegend herausragen, und dass innen in dem oberen Abschnitt der kappenartigen Heizdüse zwei Bajonettnuten an diametral gegenüberliegenden Stellen angeordnet sind, in welche die Passstifte eingreifen. Damit wird ein Kippmoment an der Heizdüse vermieden und die Dichtheit über den gesamten Umfang des Brennerkopfs und der Heizdüse wird gefördert.In a second embodiment of the quick release is a particularly reliable connection of the heating nozzle and the cutting nozzle with the Torch head according to
Sowohl die erste Ausführungsform als auch die zweite Ausführungsform des Schnellverschlusses erfordert keine aufwendigen Verriegelungsmechanismen, die bei einem Düsenwechsel zu betätigen wären.Both the first embodiment and the second embodiment of the quick release require no expensive locking mechanisms that would be operated at a nozzle change.
Als herstellungsgünstig sind gemäß Anspruch 6 die Bajonettnut bzw. Bajonettnuten aus einem Fixierkörper ausgeformt, der in dem oberen Abschnitt der kappenartigen Heizdüse fixiert ist.As production-favorable, the bayonet groove or bayonet grooves are formed from a fixing body, which is fixed in the upper portion of the cap-like heating nozzle according to
Es wird ausdrücklich darauf hingewiesen, dass die Anordnung der Passstifte und der Bajonettnuten an dem Brennerkopf bzw. an der kappenartigen Heizdüse auch vertauscht werden können, unter Aufrechterhaltung der gleichen Schnellwechselmöglichkeit.It is expressly understood that the arrangement of the dowel pins and the bayonet grooves on the burner head or on the cap-like heating nozzle can also be reversed, while maintaining the same quick-change facility.
Sowohl bei der ersten Ausführungsform als auch bei der zweiten Ausführungsform des Schnellverschlusses kann bei Dimensionierung der Bajonettnut(en) nach Anspruch 7 bis zu einem Viertel des Innenumfangs des oberen Abschnitts der kappenartigen Heizdüse bzw. der Außenkappe die kappenartige Heizdüse bzw. die Außendüse zum Düsenwechsel durch eine Vierteldrehung manuell ohne Werkzeug von dem Brennerkopf gelöst werden, wobei die Schneiddüse einfach herausgezogen werden kann. Analog umgekehrt erfolgt das Anbringen der Schneiddüse und der Heizdüse an dem Brennerkopf durch Ansetzen dieser beiden Teile von unten unter Aufbringung einer ausreichenden Anpresskraft und einer Vierteldrehung im entgegengesetzten Sinne wie zum Lösen. Die Dimensionierung der Bajonettnut(en) nach Anspruch 7 fördert einen raschen Wechsel von Schneiddüse und/oder Heizdüse sowohl manuell als auch automatisiert, insbesondere beim automatisierten Schneiden in Verbindung mit Brennschneidmaschinen und/oder Schneidrobotern.In both the first embodiment and the second embodiment of the quick release, when dimensioning the bayonet groove (s) according to
In einer anderen Ausführungsform des Verschlusses ist nach Anspruch 8 ein unterer Außenmantelabschnitt des Brennerkopfs mit einem Außengewinde versehen, und ein oberer Abschnitt der kappenartigen Heizdüse weist ein Innengewinde auf, welches in das Außengewinde des Brennerkopfs passt. Das Gewinde hat zum Schnellwechseln eine ausreichend große Steigung, was dadurch möglich ist, dass ein O-Ring nach Anspruch 1 zwischen dem Brennerkopf und der Heizdüse angeordnet wird.In another embodiment of the closure according to
Wie oben bemerkt, kann der erfindungsgemäße Schneidbrenner nach Anspruch 2 mit einer kappenartigen Heizdüsenanordnung realisiert werden, die eine kappenartige Heizdüse ist. In diesem Fall ist wenigstens das erste Verbindungselement des Schnellverschlusses an dem oberen Abschnitt der kappenartigen Heizdüse festgelegt und der obere Abschnitt der kappenartigen Heizdüse weist die nach innen vorstehende zweite ringförmige Auflagefläche auf, die der ersten ringförmigen Auflagefläche an dem unseren Außenmantelabschnitt des Brennerkopfs gegenüberliegt. Die kappenartige Heizdüse kann einstückig und damit besonders fertigungsgünstig und robust sein.As noted above, the cutting torch according to the invention can be realized according to
Es ist aber auch möglich, die Erfindung mit einer kappenartigen Heizdüsenanordnung auszuführen, die nach Anspruch 3 eine Außenkappe und eine Heizdüse umfasst, die in die Außenkappe auswechselbar eingesetzt ist. Bei einem Heizdüsenwechsel braucht somit die Außenkappe nicht ausgetauscht zu werden. Vielmehr kann es genügen, die stärker verschleißende Heizdüse auszutauschen.But it is also possible to carry out the invention with a cap-like Heizdüsenanordnung comprising according to
Bei dieser zusammengesetzten kappenartigen Heizdüsenanordnung ist das erste Verbindungselement des Schnellverschlusses, welches mit dessen zweitem Verbindungselement an dem unteren Außenmantelabschnitt des Brennerkopfs zusammenwirkt, an der Außenkappe innen festgelegt. Die der ersten ringförmigen Auflagefläche an dem unteren Außenmantelabschnitt des Brennerkopfs in diesem Fall nur mittelbar gegenüberliegende zweite ringförmige Auflagefläche, die aus der Außenkappe ausgeformt ist, stützt einen Bund an einem oberen Abschnitt der Heizdüse. Auf dem Bund ist eine Dichtungsauflagefläche für den O-Ring ausgebildet, der somit zwischen der ersten Auflagefläche und mittelbar der zweiten Auflagefläche angeordnet ist.In this composite cap-like Heizdüsenanordnung the first connection element of the quick release, which cooperates with the second connecting element on the lower outer shell portion of the burner head, fixed to the outer cap inside. The first annular bearing surface on the lower outer shell portion of the burner head in this case only indirectly opposite second annular bearing surface, which is formed from the outer cap, supports a collar at an upper portion of the heating nozzle. On the collar a sealing bearing surface for the O-ring is formed, which is thus arranged between the first bearing surface and indirectly the second bearing surface.
Die Materialien, aus denen die Heizdüse einerseits und die Außenkappe andererseits bestehen, können entsprechend den Anforderungen an diese Bestandteile der kappenartigen Heizdüsenanordnung ausgewählt sein, z.B. für die Heizdüse Kupfer und für die Außenkappe Stahl.The materials constituting the heating nozzle on the one hand and the outer cap on the other hand may be selected according to the requirements of these constituents of the cap-like heating nozzle arrangement, e.g. for the heating nozzle copper and for the outer cap steel.
Die Dichtung des in der Heizdüse gebildeten Raums nach außen könnte bei allen Ausführungsformen noch weiter gesichert werden, indem nach Anspruch 9 je eine zylindrische Dichtfläche außen an dem unteren Abschnitt des Brennerkopfs und innen an dem oberen Abschnitt der kappenartigen Heizdüse bzw. der Außenkappe ausgeformt ist, wobei vorzugsweise nach Anspruch 10 ein O-Ring zwischen den beiden zylindrischen Dichtflächen angeordnet ist.The seal of the space formed in the heating nozzle to the outside could be further secured in all embodiments by each of a cylindrical sealing surface according to
Der in die Schneiddüsenaufnahmen einschiebbare zylindrische obere Abschnitt der Schneiddüse trägt vorzugsweise gemäß Anspruch 11 zwei O-Ringe im axialen Abstand, wodurch nicht nur die Abdichtung der Schneiddüse bzw. des Schneidsauerstoffkanals verbessert wird, sondern auch die Schneiddüse in der Schneiddüsenaufnahme axial ausgerichtet wird.The insertable into the cutting nozzle receiving cylindrical upper portion of the cutting nozzle preferably carries according to claim 11, two O-rings in the axial distance, which not only the sealing of the cutting nozzle or the cutting oxygen channel is improved, but also the cutting nozzle is axially aligned in the cutting nozzle holder.
