Description

Vorrichtung zum Brennschneiden, insbesondere zum Anschneiden von schwer brennschneidbaren Werkstoffen Zusatz zur Patentanmeldung M285951b/49h (Auslegeschrift 1008 994) In der Patentanmeldung M 28595 I b/ 49 h ist eine Vorrichtung zum Brennschneiden, insbesondere zum Anschneiden von Werkstücken größerer Dicke beschrieben, bei welcher der Schneidflamme ein Eisendraht in an sich bekannter Weise mit gleichbleibender Geschwindigkeit maschinell durch ein Führungsrohr zuführbar ist.A device for cutting, in particular for incision of hard brennschneidbaren materials additional to the patent application M285951b / 49h (Auslegeschrift 1 008 994) In the patent application M 28595 I b / 49 h is a device for cutting, described in particular for the cutting of workpieces of greater thickness, in which the Cutting flame an iron wire can be fed mechanically through a guide tube in a manner known per se at a constant speed.

Nach der Erfindung wird die die Temperatur der Schneidflamme erhöhende Wirkung des laufend zugeführten Eisendrahtes noch dadurch verstärkt, daß der Eisendraht kurz vor seinem Einlauf in die Schneidflamme bis nahe an seinen Schmelzpunkt erhitzt wird. Das kann durch einen Reihen- oder Schlitzbrenner geschehen, der parallel zum Draht angeordnet ist. Zweckmäßig wird das Brenngas für diesen Hilfsbrenner von dem Hauptbrenner abgezweigt.According to the invention, the temperature of the cutting flame increases Effect of the continuously fed iron wire is reinforced by the fact that the iron wire shortly before it enters the cutting flame, it is heated to close to its melting point will. This can be done with a series or slot burner that runs parallel to the Wire is arranged. The fuel gas for this auxiliary burner is expediently from the Main burner branched off.

In der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung nach der Erfindung dargestellt. Wie im Hauptpatent ist mit 1 der Träger für den Brenner 2 bezeichnet. Am Träger 1 ist auch die Vorratstrommel 3 für den Eisendraht 4 gelagert, der durch angetriebene Förderrollen 5, 6 und das Leitrohr mit gleichbleibender Geschwindigkeit der Schneidflamme zugeführt wird, welche die Walzknüppel 8, 9 durchschneidet. Vor dem Eintritt in die Schneidflamme durchläuft der Draht die Flamme eines Reihen- oder Schlitzbrenners 10, dessen Brenngas von der Brenngasleitung des Brenners 2 abgezweigt ist.In the drawing is an embodiment of the device according to of the invention shown. As in the main patent, 1 is the carrier for the burner 2 designated. The storage drum 3 for the iron wire 4 is also mounted on the carrier 1, driven by conveyor rollers 5, 6 and the guide tube at a constant speed the cutting flame is fed, which cuts through the billets 8, 9. before the entry into the cutting flame, the wire passes through the flame of a series or slot burner 10, whose fuel gas from the fuel gas line of the burner 2 is branched off.
