Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Schneiden eines Werkstückes mit einem Laserstrahl, insbesondere mit einem Laserstrahl eines CO2-Lasers.The invention relates to a device for cutting a workpiece with a laser beam, in particular with a laser beam of a CO 2 laser.
Mit
einem CO2-Laser, insbesondere sogenannte
CO2-Bandleiterlaser,
wie sie beispielsweise aus der
Der Erfindung liegt nun die Aufgabe zu Grunde, eine Einrichtung zum Schneiden eines Werkstücks mit einem Laserstrahl, insbesondere mit einem Laserstrahl eines CO2-Lasers anzugeben, mit der auch bei kleineren räumlichen Abmessungen des Schneid kopf es das Laserstrahlschneiden dicker Werkstücke bei Verwendung eines Laserstrahls hoher Strahlqualität verbessert ist.The invention is based on the object to provide a device for cutting a workpiece with a laser beam, in particular with a laser beam of a CO 2 laser, with it even with smaller spatial dimensions of the cutting head it laser beam cutting thicker workpieces using a laser beam higher Beam quality is improved.
Die genannte Aufgabe wird gemäß der Erfindung gelöst mit einer Einrichtung mit den Merkmalen des Anspruches 1. Gemäß diesen Merkmalen enthält die Einrichtung zum Schneiden eines Werkstückes mit einem Laserstrahl, insbesondere mit einem Laserstrahl eines CO2-Lasers einen Schneidkopf, aus dem der Laserstrahl zum Werkstück hin austritt, der eine Fokussiereinrichtung zum Fokussieren des Laserstrahls sowie eine Faltspiegelanordnung zum Führen des fokussierten Laserstrahlen enthält. Durch diese Maßnahme ist es möglich, bei nach wie vor geringen Abmessungen des Schneidkopfes eine langbrennweitige Fokussiereinrichtung einzusetzen, um auf diese Weise einen größeren Strahldurchmesser im Fokus zu erhalten.The above object is achieved according to the invention with a device having the features of claim 1. According to these features, the device for cutting a workpiece with a laser beam, in particular with a laser beam of a CO 2 laser, a cutting head, from which the laser beam to the workpiece out, which includes a focusing device for focusing the laser beam and a folding mirror assembly for guiding the focused laser beams. By this measure it is possible, while still small dimensions of the cutting head to use a long focal length focusing device to obtain in this way a larger beam diameter in focus.
Eine besonders kompakte Ausführungsform wird erreicht, wenn im Schneidkopf eine der Fokussiereinrichtung in Ausbreitungsrichtung des Laserstrahls nachgeordnete Faltspiegelanordnung angeordnet ist, die insbesondere wenigstens einen ersten und einen zweiten Faltspiegel umfasst, die eine spitzwinklige Z-Faltung des Laserstrahls bewirken.A becomes particularly compact embodiment achieved when in the cutting head one of the focusing device in the propagation direction the laser beam downstream folding mirror arrangement is arranged, in particular at least a first and a second folding mirror includes, which cause an acute-angled Z-fold of the laser beam.
Zur weiteren Erläuterung der Erfindung wird auf das Ausführungsbeispiel der Zeichnung verwiesen, in deren einziger Figur ein Schneidkopf einer erfindungsgemäßen Einrichtung zu Schneiden eines Werkstückes in einer teilweise geschnittenen perspektivischen Darstellung veranschaulicht ist.to further explanation The invention is based on the embodiment referred to the drawing, in the single figure, a cutting head a device according to the invention for cutting a workpiece illustrated in a partially sectioned perspective view is.
Gemäß dieser
Figur umfasst der Schneidkopf
