Description
Die Anmeldung betrifft ein Verfahren und Anlagen zur Herstellung von 3D BautellenThe application relates to a method and equipment for the production of 3D construction cells
Rapid Prototyping und 3D-Printing sind Begriffe die in den letzten Jahren immer häufiger gefallen sind und mittlerweile vierlerlei Anwendungen gefunden haben. So gibt es heute verschiedene generative Fertigungsverfahren zur Herstellung von Bauteilen komplexer Geometrie, wie etwa SLM (Selective Laser Melting) und Auftragschweißen, alle mit ihren eigenen Stärken und Schwächen. SLM und Auftragschweißen sind sehr flexibel was die Geometrie der zu fertigenden Bauteile betrifft, werden jedoch in ihrer Einsetzbarkeit und Wirtschaftlichkeit beschränkt durch die Größe der zu erzeugenden Bauteile und der damit verbundenen Prozessdauer. Des Weiteren ist es nicht bzw. nur begrenzt möglich auskragende Strukturen ohne Stützstrukturen zu fertigen. Bis heute werden deswegen Kühlelemente wie in
Aus der Druckschrift
Ausgehend vom vorstehend angeführten Stand der Technik und oder beschriebenen Problematik liegt der vorliegenden Erfindung die Aufgabe zugrunde Verfahren und darauf aufbauende Anlagen zur schnellen und wirtschaftlichen Fertigung von Bauteilen komplexer Geometrie anzugeben.Based on the above-mentioned prior art and or problems described, the present invention has for its object to provide methods and systems based thereon for the fast and economic production of components of complex geometry.
Um sowohl den Aspekt der Schnelligkeit sowie Wirtschaftlichkeit zu erfüllen wird das zu fertigende Bauteil in beliebig viele, aber mindestens drei Teilvolumen aufgeteilt. Diese Teilvolumen können zwei Gruppen zugeordnet werden. Die drei Teilvolumen setzen sich zusammen aus einem ersten Teilvolumen (
Weiter kann ein zweites Teilvolumen (
Ein etabilierter und effizienter Prozess zum Auftragen kann mittels Plasma-Beschichtungsverfahren realisiert werden. Allerdings ist die Qualität nicht sehr hoch und gleichzeitig wird das Werkstück aufgrund der Plasma-Aufheizung thermisch belastet. Das Problem kann durch Verwendung von Laserauftragschweißen und Laser-Selektives Schmelzen vermieden werden. Dabei können zum einen die Auflösung der Struktur erhöht und zum anderen die thermischen Einflüsse minimiert werden.An established and efficient process for application can be realized by means of plasma coating processes. However, the quality is not very high and at the same time the workpiece is thermally stressed due to the plasma heating. The problem can be avoided by using laser cladding and laser selective melting. On the one hand the resolution of the structure can be increased and on the other hand the thermal influences can be minimized.

Hinsichtliche der Herstellung ist es vorteilhaft, dreidimenisonale Bauteile in Schichten aufzuteilen. Die schichtförmigen Teilvolumen weisen eine entsprechenden Strukturen und Dicke auf. Die Schichten können vorzugsweise eben oder zylinderisch sein.In terms of production, it is advantageous to divide three-dimensional components into layers. The layer-shaped partial volumes have corresponding structures and thickness. The layers may preferably be flat or cylindrical.
Als schichtförmigen Teilvolumen der ersten Gruppe können Bleche verwendet werden. Die Vorfertigung kann vorzugsweise mittels Laserschneiden ausgeführt werden.As a layer-shaped partial volume of the first group sheets can be used. The prefabrication can preferably be carried out by means of laser cutting.
Basierend auf im oben erläuterten Verfahren können Anlagen zur Herstellung von 3D-Bauteilen konzipiert werden. Um das Verfahren in Produktion umzusetzetn, besteht die mindestens aus einer abtragenden Bearbeitungsstation, einer generierenden Bearbeitungsstation, einer zusammenfügenden Bearbeitungsstation.Based on the procedure described above, systems for the production of 3D components can be designed. In order to implement the method in production, there is at least one abrading processing station, one generating processing station, one merging processing station.
Bei der abtragenden Bearbeitungsstation kann es sich um eine Fräsmaschine oder eine Laserschneidenstation handeln.The abrading processing station may be a milling machine or a laser cutting station.
In der auftragenden Bearbeitungsstation kann eine Laser-Auftragstation oder eine Laser selektive Schmelzstation verwendet werden.In the applying processing station, a laser application station or a laser selective melting station can be used.
Eine Laserschweißstation stellt bevorzugte Lösung für die zusammenfügende Bearbeitungsstation dar.A laser welding station is the preferred solution for the assembling processing station.
Des Weiteren kann eine gemeinsame Laserstrahlquelle für alle Bearbeitungsstationen genutzt werden, etwa ein Faserlaser oder fasergekoppelter Diodenlaser.Furthermore, a common laser beam source can be used for all processing stations, such as a fiber laser or fiber-coupled diode laser.
