Description

Zentraldüsen-Schneidbrenner zum Brennen von Löchern Es ist bekannt, mit den üblichen Schneidbrennern, die eine Ring- oder Lochkranzdüse für das Heizgas und eine zentrale Düse für den Sauerstoffstrahl besitzen, durch Brennbohrer kreisrunde Löcher in Werkstücken aus Stahl herzustellen. Auf diese Weise können aber keine Löcher mit drei.-eckigem, quadratischem, rechteckigem oder vieleckigem Querschnitt erzeugt werden. Man hat deshalb schon vorgeschlagen, auf das Werkstück Schablonen aus schwer brennbarem Werkstoff aufzulegen, um dem Sauerstoffstrahl den Querschnitt der gewünschten Lochform zu geben. Hiermit lassen sich aber nur Löcher verhältnismäßig kleinen Querschnitts und geringer Tiefe erzielen. Das den Sauerstoffstrahl umgebende Heizgas wird durch die Schablone abgeschirmt, so daß es lange dauert, bis die Zündtemperatur des Stahls erreicht wird. Außerdem wird nur ein Teil des Sauerstoffstrahls ausgenutzt.Central nozzle cutting torch for burning holes It is known with the usual cutting torches that have a ring or perforated ring nozzle for the heating gas and have a central nozzle for the oxygen jet, circular by torch drill Making holes in steel workpieces. But none of them can do this in this way Holes with triangular, square, rectangular or polygonal cross-sections be generated. It has therefore already been suggested to use templates on the workpiece made of flame-retardant material to give the oxygen jet the cross-section to give the desired hole shape. This only allows holes to be made in proportion Achieve small cross-section and shallow depth. The one surrounding the oxygen beam Heating gas is shielded by the stencil so that it takes a long time to reach the ignition temperature of steel is achieved. In addition, only part of the oxygen jet is used.

Die Erfindung betrifft einen Brenner zum Brennbohren von Löchern, der diese Nachteile nicht besitzt. Ein Brenner nach der Erfindung ist mit einer Ring- oder Lochkranzdüse für den Sauerstoff, die kongruent zum Umfang des zu bohrenden Lochquerschnitts. gestaltet bzw. angeordnet sind, und einer zentralen runden Düse für das Heizgas versehen. Im Gegensatz zu den üblichen Schneidbrennern umhüllt also der Sauerstoff das Heizgas. Dabei. wird das Heizgas voll ausgenutzt, und der Sauerstoff schneidet ein maßhaltiges Loch auch bei großer Stärke des Werkstücks. Das Brennbohren nnit einem Brenner nach der Erfindung eigne sich besonders für nachträgliches" Bohren von montierten Werkstücken, z. B. von verlegten. Trägern oder von Eisenbahnschwellen auf der Strecke.The invention relates to a burner for flame drilling holes, which does not have these disadvantages. A burner according to the invention is with a Ring or perforated wreath nozzle for the oxygen, which is congruent to the circumference of the hole to be drilled Hole cross-section. are designed or arranged, and a central round nozzle for the heating gas. In contrast to the usual cutting torches, it is wrapped the oxygen the heating gas. Included. the heating gas is fully used, and the oxygen cuts a dimensionally accurate hole even if the workpiece is very thick. The torch drilling with a burner according to the invention is particularly suitable for subsequent " Drilling of assembled workpieces, e.g. B. of misplaced. Girders or from railway sleepers on the route.
