Description
Die Erfindung bezieht sich auf eine Laserauftragsvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a laser application device according to the preamble of
Im Einzelnen bezieht sich die Erfindung auf eine Laserauftragsvorrichtung mit einem Maschinenbett, auf dessen Oberfläche ein Pulvermaterial auftragbar ist, welches mittels eines Lasers schichtweise aufschmelzbar ist, um ein Bauteil zu erzeugen.In detail, the invention relates to a laser application device with a machine bed, on the surface of which a powder material can be applied, which can be melted in layers by means of a laser in order to produce a component.
Die Erfindung betrifft somit eine DLD (Direct Laser Depositioning)-Vorrichtung für die Herstellung von Bauteilen mithilfe eines schichtweisen Laserschmelzverfahrens, bei dem mittels Laser ein metallisches, keramisches oder nicht-metallisches Pulver schichtweise geschmolzen wird, um so ein Bauteil in Schichten aufzubauen.The invention thus relates to a DLD (Direct Laser Depositioning) device for the manufacture of components by means of a layered laser melting process, in which a metallic, ceramic or non-metallic powder is melted by layers in order to build up a component in layers.
Diese Art von Vorrichtungen bestehen neben einer Hülle, einer Steuerung, einem Materialvorrat und einer Materialbereitstellungsvorrichtung aus einem sogenannten Maschinenbett
Beim Stand der Technik werden ein oder mehrere Laser
Die Herstellung des Bauteils
Daher hängt die Qualität des Bauteils (Oberflächengüte, Porosität, Materialeigenschaften) stark von der Schmelzgeschwindigkeit ab, d.h., eine hohe Geschwindigkeit bedingt geringere Qualität. Daher ist die Verarbeitungsgeschwindigkeit stark limitiert.Therefore, the quality of the component (surface quality, porosity, material properties) depends strongly on the melting rate, i.e., a high speed results in lower quality. Therefore, the processing speed is severely limited.
Der Erfindung liegt die Aufgabe zugrunde, eine Laserauftragsvorrichtung der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau und einfacher, kostengünstiger Herstellbarkeit einen hohen Wirkungsgrad aufweist und mittels derer die Herstellungszeit von Bauteilen reduziert werden kann.The invention has for its object to provide a laser applicator device of the type mentioned, which has a high efficiency with a simple structure and simple, cost manufacturability and by means of which the production time of components can be reduced.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Anspruchs 1 gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention the object is achieved by the combination of features of
Erfindungsgemäß ist somit vorgesehen, dass das Maschinenbett zumindest eine Ausnehmung aufweist, in welcher eine verschiebbar angeordnete Stützstruktur gelagert ist. According to the invention it is thus provided that the machine bed has at least one recess in which a displaceably arranged support structure is mounted.
Der erfindungsgemäßen Lösung liegt somit der Gedanke zugrunde, eine wiederverwendbare Stützstruktur vorzusehen. Diese ist in dem Maschinenbett angeordnet und kann dann zur Anwendung kommen, wenn sie zur Abstützung von Bereichen des zu erzeugenden Bauteils benötigt wird. Es ist somit nicht erforderlich, die Stützstruktur selbst aus dem Pulvermaterial zu erzeugen, so wie dies aus dem Stand der Technik bekannt ist. Vielmehr ist bereits eine geeignete Stützstruktur vorhanden, die in einfacher Weise zur Anwendung gelangen kann. Hierdurch verkürzt sich der Zeitraum für die Herstellung des Bauteils ganz erheblich, da lediglich das Bauteil selbst aus dem Pulvermaterial schichtweise aufgeschmolzen werden muss, nicht jedoch die Stützstruktur.The solution according to the invention is therefore based on the idea of providing a reusable support structure. This is arranged in the machine bed and can then be used when it is needed to support areas of the component to be produced. It is thus not necessary to produce the support structure itself from the powder material, as known from the prior art. Rather, a suitable support structure is already present, which can be used in a simple manner. As a result, the period for the production of the component is shortened considerably, since only the component itself from the powder material must be melted in layers, but not the support structure.
Bevorzugterweise ist die Stützstruktur mittels einer Betätigungsvorrichtung in der Ausnehmung verschiebbar. Die Betätigungsvorrichtung ist bevorzugterweise unterhalb des Maschinenbetts angeordnet und kann beispielsweise einen Elektroantrieb umfassen. Hierbei ist es möglich, die Bewegung der Stützstruktur präzise zu steuern und zu überwachen. Preferably, the support structure is displaceable by means of an actuating device in the recess. The actuating device is preferably arranged below the machine bed and may for example comprise an electric drive. In this case, it is possible to precisely control and monitor the movement of the support structure.
Die Stützstruktur wird nun während des Bearbeitungsvorganges schrittweise mit Fortschritt des Pulverauftrages gemäß der Pulverauftragsdicke verfahren, wobei zu gewährleisten ist, dass während des Bearbeitungsvorganges die Stützstruktur bevorzugterweise nicht über die Oberfläche des Maschinenbetts vorsteht, um den Pulverauftrag und den schichtweisen Aufbau des Werkstücks nicht zu behindern. Sobald die verfahrbare Stützstruktur die vorgesehene Position im Pulverbett für die Herstellung des abzustützenden Bauteiles erreicht hat, wird der Verfahrvorgang gestoppt.The support structure is now moved during the processing step by step with progress of the powder application according to the powder application thickness, it being ensured that during the machining process, the support structure preferably does not project beyond the surface of the machine bed, so as not to hinder the powder application and the layered structure of the workpiece. Once the movable support structure has reached the intended position in the powder bed for the production of the component to be supported, the movement process is stopped.
Auf der Stützstruktur wird dann der abzustützende Bereich des Bauteils, beispielsweise ein auskragender Bereich, ausgebildet. Dabei wird die Stützstruktur üblicherweise mit diesem Bereich des Bauteils verbunden. Nach Fertigstellung des Bauteils wird die Stützstruktur zusammen mit dem Bauteil entnommen und nachfolgend von diesem getrennt. Das Trennen kann beispielsweise mittels eines Funkenerosionsdrahtes erfolgen. Hierbei wird nur sehr wenig Material von der Oberfläche der Stützstruktur entfernt, so dass diese wiederverwendbar ist.The region of the component to be supported, for example a projecting region, is then formed on the support structure. In this case, the support structure is usually connected to this region of the component. After completion of the component, the support structure is removed together with the component and subsequently separated from it. The separation can for example by means of a Spark erosion wire done. In this case, only very little material is removed from the surface of the support structure, so that it is reusable.
Die erfindungsgemäße Ausgestaltung eignet sich insbesondere für die Serienproduktion von Bauteilen, bei welchen stets die gleichen Stützstrukturen Verwendung finden. Erfindungsgemäß ist es auch möglich, in dem Maschinenbett mehrere Ausnehmungen vorzusehen und die nicht benötigten Ausnehmungen zu verschließen, beispielsweise mit einem Blindteil.The embodiment of the invention is particularly suitable for the mass production of components in which always find the same support structures use. According to the invention, it is also possible to provide a plurality of recesses in the machine bed and to close the unused recesses, for example with a blind part.
Da häufig das Volumen der Stützstruktur und die des Bauteils sehr ähnlich sind, kann eine Zeitersparnis von ca. 50% und eine ebenso hohe Kostenersparnis pro Bauteil erreicht werden. Es werden außerdem die Kosten für das Pulver für die Stützstruktur eingespart, d.h. die Materialkosten pro Bauteil können ebenfalls halbiert werden.Since often the volume of the support structure and the component are very similar, a time savings of about 50% and an equally high cost savings per component can be achieved. It also saves the cost of the powder for the support structure, i. The material costs per component can also be halved.
