Description

Verfahren zum Brennschneiden einer Tulpenflankenform in die Stirnflächen von miteinander zu verschweißenden Blechen Zum Brennschneiden einer Tulpenflankenform ist ein Verfahren bekannt, bei dem zunächst in die Stirnfläche der Blechkante in der Nähe ihres unteren Randes und parallel zu diesem mit Hilfe eines autogenen Schneidbrenners eine halbzylindrische Hohlkehle angeschnitten und dann ein Gehrungsschnitt ausgeführt wird, der die über der Hohlkehle liegende Kante wegschneidet. Bei diesem Verfahren kann der Gehrungsschnitt unter Umständen den unteren Rand der Hohlkehle beschädigen oder gar wegschneiden, oder es setzt sich Schlacke in der Hohlkehle fest.Process for flame cutting a tulip flank shape in the end faces of sheets to be welded together For flame cutting a tulip flank shape a method is known in which initially in the end face of the sheet metal edge in near its lower edge and parallel to it with the help of an oxy-fuel cutting torch cut a semi-cylindrical groove and then made a miter cut which cuts away the edge overlying the fillet. In this procedure the miter cut may damage the lower edge of the fillet or even cut away, or slag sticks in the groove.

Um dies zu vermeiden, wird erfindungsgemäß vorgeschlagen, während der Ausführung des Gehrungsschnitts in die Hohlkehle einen Luft- oder inerten Gasstrahl einzublasen, der den Schneidsauerstoffstrahl von dem unteren Rand der Hohlkehle ablenkt und das Festsetzen von Schlacke in der Hohlkehle verhindert.To avoid this, it is proposed according to the invention while the execution of the miter cut in the fillet an air or inert gas jet to blow the cutting oxygen jet from the lower edge of the fillet deflects and prevents slag from settling in the groove.
