Abstract

Die Erfindung betrifft ein Verfahren zum automatischen Überwachen einer Flamme (69) beim thermischen Bear­ beiten von Werkstücken mit einem Brenner (10), insbeson­ dere beim Schneiden mit einem Autogrenbrenner, wobei zündfähige Gase und/oder Gasgemische dem Brenner (10) zugeführt werden und durch eine Zündeinrichtung die Gase zur Flammbildung gezündet werden. The invention relates to a method for automatic Monitoring a flame (69) at the thermal bear workpieces with a burner (10), in particular when cutting with an autogren torch, whereby ignitable gases and / or gas mixtures to the burner (10) be supplied and the gases through an ignition device be ignited to form a flame.

Um die Verwendung von zusätzlichen Meßgasen, sowie außerhalb des Brenners (10) angeordnete Sensoren zur automatischen Überwachung der Flamme (69) zu vermeiden und eine Einrichtung zum automatischen Überwachen der Flamme zu schaffen, die einfach aufgebaut sowie kostengün­ stig realisierbar ist und zu keiner den Bearbeitungsvorgang störenden Gerätegeometrie fuhrt, wird mindestens während des Zündens in einem Bereich, in dem sich die Flamme (69) ausbildet, vorzugsweise in der Nähe des sich ausbildenden Flammkegels (68) der dort vorhandene Druck erfaßt und einer Überwachungsvorrichtung zugeführt. To the use of additional measurement gases, as well sensors arranged outside the burner (10) for to avoid automatic monitoring of the flame (69) and a device for automatically monitoring the To create flame that is easy to set up and inexpensive is realizable and none of the machining process disruptive device geometry leads, at least during ignition in an area where the flame (69) trains, preferably in the vicinity of the training Flame cone (68) detects the pressure there and fed to a monitoring device.
