Abstract

The invention relates to a double-walled oxyacetylene cutter nozzle comprising mirror optics for laser cutting devices for the oxyacetylene cutting of metal sheets from steel, structural steel, shipbuilding steel, high-grade steel, aluminium or non-ferrous metal. To this end, the inventive double-walled oxyacetylene cutter nozzle (1) has an intermediate gap (4) located between the inner nozzle (2) and the outer nozzle (3) and configured as a retaining area for the cutting gas.

Description

Die Erfindung betrifft eine Doppelwand-Brennschneiddüse mit Spiegeloptik für Laserschneidgeräte.The invention relates to a double-wall flame cutting nozzle with mirror optics for Laser cutters.

Die bisher ausschließlich zum Laserschmelzschneiden von Metallblechen aus Stahl, Baustahl, Schiffsbaustahl, Edelstahl, Aluminium oder Buntmetallen in einem Druckbereich von mehr als 3 bar bis etwa 25 bar in Laserschneidgeräten, wie beispielsweise in den bekannten LaserMat®-Laserschneidgeräten der Firma Messer Cutting & Welding AG, D-64823 Groß-Umstadt, eingesetzten, aufgrund der hohen Temperaturbelastung anstelle einer Linse mit einer den CO2-Laserstrahl fokussierenden Spiegeloptik ausgerüsteten oder teilweise drehbaren Schneiddüsen sind für das, in einem Druckbereich von 0,2 bar bis etwa 3 bar erfolgende Laserbrennschneiden ungeeignet, da sie keinen Stauraum für den beim Laserbrennschneiden im Niederdruckbereich erforderlichen Druckaufbau im Schneidgas aufweisen.So far exclusively for laser fusion cutting of metal sheets from steel, structural steel, shipbuilding steel, stainless steel, aluminum or non-ferrous metals in a pressure range from more than 3 bar to about 25 bar in laser cutting devices, such as in the well-known LaserMat® laser cutting devices from Messer Cutting & Welding AG , D-64823 Groß-Umstadt, because of the high temperature load instead of a lens equipped with a CO 2 laser beam focusing mirror optics or partially rotatable cutting nozzles are unsuitable for laser flame cutting in a pressure range from 0.2 bar to about 3 bar , since they have no storage space for the pressure build-up in the cutting gas required for laser flame cutting in the low pressure range.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine derartige, kostengünstig herstellbare Schneiddüse mit Spiegeloptik für das Laserbrennschneiden zur Verfügung zu stellen.The invention is therefore based on the object of such an inexpensive one producible cutting nozzle with mirror optics for laser flame cutting for To make available.

Gelöst wurde die Aufgabe durch eine Doppelwand-Brennschneiddüse mit den Merkmalen von Anspruch 1.The task was solved by a double wall flame cutting nozzle with the Features of claim 1.

Zum Einsatz der erfindungsgemäßen, in üblichen Abmessungen gefertigten Doppelwand-Brennschneiddüse findet der bereits im Schneidkopf vorhandene Schneidgaseingang Verwendung. For the use of the inventive, manufactured in usual dimensions The double wall flame cutting nozzle will find the one already in the cutting head Cutting gas inlet use.  

Zum bestimmungsgemäßen Einsatz wird die Innendüse der Doppelwand- Brennschneiddüse in der Linsen-Position im Schneidkopf des Laserschneidgerätes zweckentsprechend angeordnet (eingeschraubt).The internal nozzle of the double wall Flame cutting nozzle in the lens position in the cutting head of the laser cutting device appropriately arranged (screwed in).

Der zwischen der Innendüse und der Außendüse der Doppelwand- Brennschneiddüse angeordnete Stauraum ist so ausgebildet, dass die zum Brennschneiden im Schneidgas erforderliche Druckerzeugung gewährleistet ist.The between the inner nozzle and the outer nozzle of the double wall Flame cutting nozzle arranged storage space is designed so that the for Flame cutting in the cutting gas required pressure generation is guaranteed.

Die vorzugsweise in den Laserschneidköpfen von LaserMat®-Schneidgeräten eingesetzte Doppelwand-Brennschneiddüse ist insbesondere zur Herstellung von flachen Bauteilen wie Metallblechen aus Stahl, Baustahl oder Schiffsbaustahl, Edelstahl, Aluminium oder Buntmetallen vorteilhaft einsetzbar.Preferably in the laser cutting heads of LaserMat® cutting devices Double-wall cutting nozzle used is especially for the production of flat components such as sheet metal made of steel, structural steel or shipbuilding steel, Stainless steel, aluminum or non-ferrous metals can be used advantageously.

Die erfindungsgemäße Doppelwand-Brennschneiddüse wird anhand der nachfolgenden Zeichnung näher erläutert.The double-wall flame cutting nozzle according to the invention is based on the following drawing explained in more detail.

Die einzige Figur der Zeichnung zeigt eine, üblicherweise aus Kupfer oder Hartmetall, wie beispielsweise Wolfram, gefertigte Doppelwand-Brennschneiddüse 1 mit einer den Laserstrahl leitenden Innendüse 2 und einer auf dieser lösbar befestigten Außendüse 3 mit einem zwischen der Innen- und Außendüse 2, 3 angeordneten Zwischenraum 4, welcher als Schneidgas-Stauraum mit einem Schneidgas-Eingang 5 zur im Lasergas erforderlichen Druckerzeugung ausgebildet ist.The single figure of the drawing shows a arranged usually made of copper or carbide, such as tungsten, made double-torch nozzle 1 with a conducting the laser beam inside nozzle 2 and an on this removably attached outer nozzle 3 having a between the inner and outer nozzle 2, 3 Intermediate space 4 , which is designed as a cutting gas storage space with a cutting gas inlet 5 for the pressure generation required in the laser gas.

Zum bestimmungsgemäßen Einsatz zum Laserbrennschneiden von Stahl, Baustahl oder Schiffsbaustahl, Edelstahl, Aluminium oder Buntmetallen wird die Innendüse 2 der Doppelwand-Brennschneiddüse 1 im Linsen-Bereich in einem bildlich nicht dargestellten Laserschneidkopf eines ebenfalls bildlich nicht dargestellten Laserschneidgerätes eingeschraubt.For the intended use for laser flame cutting of steel, structural steel or shipbuilding steel, stainless steel, aluminum or non-ferrous metals, the inner nozzle 2 of the double-wall flame cutting nozzle 1 is screwed into the lens area in a laser cutting head (not shown) of a laser cutting device ( also not shown).
