Description
Die Erfindung betrifft eine Laserbearbeitungsmaschine zum Bearbeiten eines Rohres mittels eines Laserstrahls, mit Mitteln zur Benetzung und/oder zur Kühlung der Rohrinnenwand vor oder während der Laserbearbeitung mittels eines Fluids, wobei die Mittel zur Benetzung und/oder zur Kühlung der Rohrinnenwand eine Düse für Fluid aufweisen, die in das Rohr in dessen Längsrichtung eingeführt ist.The The invention relates to a laser processing machine for processing a tube by means of a laser beam, with means for wetting and / or for cooling the pipe inner wall before or during the laser processing by means of a fluid, wherein the means for Wetting and / or for cooling the pipe inner wall a nozzle for fluid flowing into the tube in its longitudinal direction is introduced.
Beim Laserschneiden kommt es vor, dass Spritzer oder Schlacke im Inneren des bearbeiteten Werkstückes der Schnittkante gegenüberliegend an dem Werkstück anhaften. Dies macht eine kostenintensive Nachbearbeitung des Werkstückes beispielsweise durch Sandstrahlen erforderlich. Derartige Probleme treten insbesondere an Werkstücken aus Edelstahl auf.At the Laser cutting happens that splash or slag inside the machined workpiece of the cutting edge opposite adhere to the workpiece. This makes a costly Post-processing of the workpiece, for example by sandblasting required. Such problems occur especially on workpieces made of stainless steel.
Ebenso können Verfärbungen, die durch einen Laserenergieüberschuss beim Einstechen oder Schneiden an der einer Schnittkante gegenüberlie genden Seite des Werkstückes verursacht werden zu einer kostenintensiven Nachbearbeitung beispielsweise durch Schleifen oder Polieren führen. An Rohren mit großer Wandstärke und filigranen Konturen kann es in Folge der starken Erwärmung im Material zu Ausbrennungen kommen. Derartige Probleme treten insbesondere an Werkstücken aus Baustahl auf.As well can discolorations caused by a laser energy surplus when piercing or cutting at a cutting edge gegenüberlie ing Side of the workpiece can be caused to a costly Post-processing, for example, by grinding or polishing. On pipes with large wall thickness and filigree Contours may increase as a result of the intense warming in the material Burns come. Such problems occur in particular Workpieces made of structural steel.
Gattungsgemäßer
Stand der Technik ist bekannt aus
Bearbeitungsbedingte Anhaftungen im Rohrinneren noch wirksamer zu verhindern, ist Aufgabe der vorliegenden Erfindung.Conditional processing To prevent adhesions inside the pipe even more effectively is the task of present invention.
Diese Aufgabe wird durch die Laserbearbeitungsmaschine nach Anspruch 1 gelöst. Im Falle der Erfindung wird die Düse für das Fluid zur Benetzung und/oder zur Kühlung der Rohrinnenwand in Rohrlängsrichtung vor der Bearbeitungsstelle des Laserstrahls angeordnet. Von dort aus richtet die Düse einen Fluidkegel sowohl auf Höhe der Bearbeitungsstelle des Laserstrahls als auch der Bearbeitungsstelle des Laserstrahls diametral gegenüberliegend auf die Rohrinnenwand. Das Benetzungs- und/oder Kühlmedium kann in optimal dosierter Menge eingebracht werden. Die Benetzung und/oder Kühlung des betreffenden Rohres ist zu unterschiedlichen Zeitpunkten möglich. Bei einer Benetzung beziehungsweise Kühlung während der Laserbearbeitung kann eine direkte Kühlung der Schnittkante erfolgen. Das Fluid kann außerdem zu der Seite geführt werden, welche der Bearbeitungsstelle des Laserstrahls gegenüberliegt. Das Anhaften von Materialspritzern insbesondere bei Werkstücken aus Edelstahl (VA) wird verhindert. Bei der Baustahlbearbeitung tritt ein geringerer Wärmeverzug auf und/oder die Schnittqualität wird verbessert. Bei einer gleichzeitig mit der Laserbearbeitung erfolgenden Benetzung und/oder Kühlung werden Prozessrauche gebunden. Infolgedessen ist es denkbar, dass auf Einheiten zum Absaugen von Prozessrauchen verzichtet werden kann.These The object is achieved by the laser processing machine according to claim 1 solved. In the case of the invention, the nozzle for the fluid for wetting and / or for cooling the pipe inner wall in the tube longitudinal direction in front of the processing point of the laser beam arranged. From there, the nozzle directs a fluid cone both at the level of the processing point of the laser beam and the processing point of the laser beam diametrically opposite the pipe inner wall. The wetting and / or cooling medium can be introduced in optimally dosed amount. The wetting and / or cooling of the pipe in question is too different Times possible. In a wetting or Cooling during laser processing can be a direct cooling of the cutting edge done. The fluid can also be led to the page which the Machining point of the laser beam opposite. The Adherence of material splashes, especially for workpieces made of stainless steel (VA) is prevented. In the construction steel processing occurs less heat distortion and / or the quality of cut will be improved. At one at the same time as laser processing subsequent wetting and / or cooling become process fumes bound. As a result, it is conceivable that on suction units can be dispensed with by process smoking.
Im Falle einer bevorzugten Erfindungsbauart ist ein Schlauchsystem zur Benetzung und/oder zur Kühlung der Rohrinnenwand vorgesehen, dessen flexibler Schlauch mit Hilfe von Druckluft in das zu bearbeitende Werkstück eingeführt und dort positioniert werden kann (Anspruch 2). Das Schlauchsystem ermöglicht es, die Benetzung und/oder Kühlung entweder während Bearbeitungsnebenzeiten oder während der Laserbearbeitung durchzuführen.in the Case of a preferred Erfindungsbauart is a hose system provided for wetting and / or cooling of the pipe inner wall, its flexible hose with the help of compressed air in the processed Workpiece introduced and positioned there can (claim 2). The hose system allows the Wetting and / or cooling either during processing auxiliary times or during laser processing.
In weiterer bevorzugter Ausgestaltung der Erfindung dient zum Einführen und Positionieren des Schlauches eine an einem Schlauchende vorgesehene Düse mit Mitteln zum Rückstau der Druckluft (Anspruch 3).In Another preferred embodiment of the invention is used for insertion and positioning the hose one provided at a hose end Nozzle with means for backflow of compressed air (claim 3).
Ein doppelwandig ausgebildeter Schlauch (Anspruch 5) ermöglicht es, dass sowohl Druckluft als auch Fluid zur Benetzung und/oder zur Kühlung der Rohrinnenwand zu der Düse am Schlauchende strömen können. Bei dem Fluid muss es sich nicht zwingend um Kühlwasser handeln. Denkbar sind auch ein Wasser-/Öl-Gemisch, Wasser mit Spülmittel etc.A double-walled hose (claim 5) allows both compressed air and fluid for wetting and / or cooling of the pipe inner wall to flow to the nozzle at the hose end. The fluid does not necessarily have to be cooling water. Also conceivable are a water / oil mixture, water with detergent Etc.
Im Falle einer weiteren bevorzugten Ausführungsform der Erfindung umfasst das Schlauchsystem eine Aufrolleinheit für den Schlauch (Anspruch 6). Mittels der Aufrolleinheit kann der Schlauch bevorratet und straff gehalten werden.in the Case of a further preferred embodiment of the invention The hose system includes a reel unit for the Hose (claim 6). By means of the reeling unit, the hose stockpiled and kept tight.
Die Mittel zur Benetzung und/oder zur Kühlung der Rohrinnenwand können an der Laserbearbeitungsmaschine beliebig angeordnet sein. Denkbar sind eine Anordnung auf einer Vorschubstation für Werkstücke oder auf einer Beladevorrichtung für Werkstücke (Ansprüche 7, 8).The Means for wetting and / or for cooling the pipe inner wall can be arranged arbitrarily on the laser processing machine be. Conceivable are an arrangement on a feed station for Workpieces or on a loading device for workpieces (Claims 7, 8).
