Description
Die Erfindung betrifft eine Einrichtung zum Brennschneiden mittels Sauerstoff.The invention relates to a device for flame cutting by means of Oxygen.
Für d'as autogene Schneiden von Blechen oder sonstigen Werkstücken bediente man sich bekanntermaßen einer Einrichtung, bei welcher um die Sauerstoffdüse, die den Sauerstoff für das eigentliche Schneiden zuführte, noch eine Gasdüse angeordnet war, welche dem Werkstück die nötige Temperatur .geben sollte, damit der Werkstoff zum Zünden bzw. zum Verbrennen oder Schmelzen gebracht werden konnte.For the autogenous cutting of sheet metal or other workpieces As is known, a device was used in which the oxygen nozzle, which supplied the oxygen for the actual cutting, a gas nozzle was also arranged which should give the workpiece the necessary temperature so that the material could be caused to ignite or burn or melt.
Diesem Bekannten gegenüber wird erfindungsgemäß vorgeschlagen, zum Erhitzen des Werkstückes eine mit Hoch- oder Niederfrequenzstrom gespeiste elektrische Heizvorrichtung zu wählen, .die in .dem Werkstück ,derart große Wirbelströme erzeugt, daß das: Werkstück an den .im Bereich der Heizspule liegenden Stellen stark erhitzt wird, so:-gar zum Schmelzen gebracht werden kann, so @daß das Werkstück die für das Schneiden durch den Sauerstoffstrom benötigte und erforderliche Temperatur aufweist. Die Heizspule der Heizvorrichtung ist,die Sauerstoffdüse umlagernd angeordnet. Man kann aber auch, da man durch die Heizspule jede beliebige Temperatur in. dem Werkstück erreichen kann., die- elektrische Heizvorrichtung der Sauerstoffdüse vorauslaufen lassen und alsdann trotzdem noch das Werkstück durch den Sauerstoffstrom schneiden. Des weiteren kann der Sauerstoffdüse eine weitere elektrische Heizvorrichtung nachgeordnet @sein, die alsdann dem Nachglühen der Schnittflächen dhent.In relation to this known it is proposed according to the invention to Heating of the workpiece is an electric one fed with high or low frequency current Select a heating device that generates such large eddy currents in the workpiece that the: workpiece heats up strongly at the points in the area of the heating coil is so: -gar can be brought to melt, so @ that the workpiece is the for the cutting by the oxygen flow has the required and required temperature. The heating coil of the heating device is arranged around the oxygen nozzle. Man but can also, since the heating coil can be used to set any temperature in the workpiece can achieve., the electrical heater precedes the oxygen nozzle and then still cut the workpiece through the flow of oxygen. Furthermore, a further electrical heating device can be arranged downstream of the oxygen nozzle @be, which then dhent the afterglow of the cut surfaces.
Die elektrische Erwärmung eines Werkstückes und die Induktionserhitzung wie auch das Vor- und Nachwärmen beim Brennschneiden sind zwar an sich allgemein bekannt, .der Vorschlag jedoch, zum Brennschneiden mittels Sauerstoff sich einer mit Hoch- oder Niederfrequenzstrom gespeisten, das Erhitzen des Werkstückes besorgenden elektrischen Heizvorrichtung zu. bedienen, ist diesem Bekannten gegenüber neu und von wesentlichen Vorteilen begleitet, die insbesondere darin bestehen, daß günstigere Schneid- und Abkühlungsbedingungen für zum Aufhärten neigende Stähle: geschaffen werden. In der Zeichnung ist der 1Gegenstand der Erfindung in einer lbeispielsweisen Ansführungsform im senkrechten Mittelschnitt und in Draufsicht veranschaulicht.The electrical heating of a workpiece and induction heating as well as preheating and post-heating during flame cutting are general in themselves known, the suggestion, however, to use oxygen for flame cutting fed with high or low frequency current, heat the workpiece electric heater too. use is new to this acquaintance and Accompanied by significant advantages, which are in particular that cheaper Cutting and cooling conditions for steels that tend to harden: created will. In the drawing, the subject matter of the invention is shown in an exemplary manner Form of embodiment illustrated in vertical center section and in plan view.
Mit i ist das zu schneidende Werkstück, mit 2 ,die S.auerstoffdüse und mit 3 die mit, Hoch- oder Niederfrequenzstrom gespeiste elektrische Heizvorrichtung bezeichnet, deren Heizspule 4 nach dem gewählten Beispiel die Sauerstoffdüse 2 umlagernd angeordnet ist. Die Heizvorrichtung 3@ kann wasserader luftgekühlt sein und hat eine dementsprechende geeignete Gestaltung, wie sie _z. B. in .dien Abbildungen veranschaulicht ist.With i the workpiece to be cut, with 2, the oxygen nozzle and with 3 the electric heating device fed with high or low frequency current denotes, the heating coil 4 of which, according to the example chosen, surrounds the oxygen nozzle 2 is arranged. The heating device 3 @ can be air-cooled and has water veins a correspondingly suitable design, as it _z. B. in the illustrations is illustrated.
