Einrichtung zur Nachbearbeitung eines aus einem pulverförmigen oder körnigen Material hergestellten ObjektesDevice for post-processing an object made from a powdery or granular material
Die vorliegende Erfindung betrifft eine Einrichtung zur Nachbearbeitung eines aus einem pulverförmigen oder körnigen Material hergestellten Objektes.The present invention relates to a device for post-processing an object made of a powdery or granular material.
Eine Vorrichtung und ein Verfahren zum Herstellen eines dreidimensionalen Objektes mittels Lasersintern ist aus der DE-C-43 00 478 bekannt.A device and a method for producing a three-dimensional object by means of laser sintering are known from DE-C-43 00 478.
Ein durch Lasersintern gebildetes Objekt muß nach dem Lasersintern von dem noch anhaftenden ungesinterten Pulver befreit werden. Dies geschieht üblicherweise auf einer Plattform, in die ein Sieb eingebaut ist. Das von dem Objekt abgelöste Pulver fällt durch das Sieb zur Wiederverwendung in einen Behälter.An object formed by laser sintering must be freed from the unsintered powder that is still adhering to it after laser sintering. This is usually done on a platform into which a sieve is built. The powder detached from the object falls through the sieve into a container for reuse.
Insbesondere bei Sinterung des Objekts in einem mitgesinterten Behälter mit Boden-, Wand- und Deckelschicht fällt eine große Menge sowohl an ungesintertem Pulver als auch an nicht mehr gebrauchten verfestigten Teilen wie z.B. den Boden- und Wandschichten an. Diese Mengen können von dem Sieb nicht in ausreichend kurzer Zeit getrennt werden. Ferner führt die kleine Korngröße des ungesinterten Pulvers zu einer Bildung von Pulverstaubwolken.Particularly when the object is sintered in a co-sintered container with a base, wall and lid layer, a large amount of both unsintered powder and solidified parts that are no longer needed, such as the base and wall layers, are produced. These quantities cannot be separated by the sieve in a sufficiently short time. Furthermore, the small grain size of the unsintered powder leads to the formation of powder dust clouds.
Aufgabe der Erfindung ist es, die Nachbehandelungszeit, insbesondere die Reinigungszeit, eines Objektes zu verkürzen undThe object of the invention is to shorten the post-treatment time, in particular the cleaning time, of an object and

Eine Einrichtung zur Nachbearbeitung eines aus einem pulverförmigen oder körnigen Material, z.B. Metall-, Keramik-, oder Kunststoffpulver oder kunstharzummantelter Sand, hergestellten bzw. gesinterten Objektes umfaßt ein im wesentlichen quaderförmigen Metallrahmen 1. Der Metallrahmen weist eine Oberseite, eine Unterseite und vier Seiten auf. Die vier Seiten sind mit Holzplatten verkleidet. In einer verkleideten Seite ist eine Tür 2 vorgesehen.A device for post-processing an object made or sintered from a powdery or granular material, e.g. metal, ceramic, or plastic powder or resin-coated sand, comprises an essentially cuboid-shaped metal frame 1. The metal frame has a top, a bottom and four sides. The four sides are covered with wooden panels. A door 2 is provided in one covered side.
Auf der Oberseite des Metallrahmens 1 ist ein zweiteiliger quaderförmiger Behälter 3 angeordnet. Ein erster Teil 11 des Behälters 3 weist eine Bodenplatte 4, eine mit der Bodenplatte fest verbundene Rückwand 13, zwei mit jeweils einer Kante der Bodenplatte 3 und der Rückwand 13 fest verbundene erste dreieckförmige Seitenwände 14 und einen niedrigen mit der derA two-part cuboid-shaped container 3 is arranged on the top of the metal frame 1. A first part 11 of the container 3 has a base plate 4, a rear wall 13 firmly connected to the base plate, two first triangular side walls 14 firmly connected to one edge of the base plate 3 and the rear wall 13, and a low part 12 of the
Rückwand 13 gegenüberliegen Vorderkante der Bodenplatte 4 fest verbundenen Vordersteg 15 auf. Ein zweiter Teil 12 des Behälters 3 ist als Haube mit einer Vorderwand 6, einer mit der Vorderwand 6 fest verbundenen Deckwand 5 und zwei mit jeweils einer Kante der Vorderwand 6 und der Deckwand 5 fest verbundene zweite Seitenwände 16 ausgebildet. Die Deckwand 5 ist über ein Scharnier mit der Rückwand 13 des Behälters 3 verbunden. Dadurch ist die Haube aufschwenkbar und das Behälterinnere von außen leicht zugänglich.The front edge of the base plate 4 is opposite the rear wall 13 and has a front web 15 that is firmly connected to it. A second part 12 of the container 3 is designed as a hood with a front wall 6, a top wall 5 that is firmly connected to the front wall 6 and two second side walls 16 that are firmly connected to one edge each of the front wall 6 and the top wall 5. The top wall 5 is connected to the rear wall 13 of the container 3 via a hinge. This means that the hood can be swung open and the inside of the container is easily accessible from the outside.
In der Vorderwand 6 sind zwei in einem Abstand voneinander angeordnete Ausnehmungen 8 angeordnet. Die Ausnehmungen 8 weisen bevorzugt eine kreisförmige Außenkontur auf. In jeder Ausnehmung 8 ist ein Handschuh angeordnet, der mit seinem offenen Ende so mit der Ausnehmung 8 verbunden ist, daß die Ausnehmung 8 durch den Handschuh abgedichtet ist. Der Behälter 3 ist somit als Handschuhkasten ausgebildet.Two recesses 8 are arranged at a distance from one another in the front wall 6. The recesses 8 preferably have a circular outer contour. A glove is arranged in each recess 8, which is connected with its open end to the recess 8 in such a way that the recess 8 is sealed by the glove. The container 3 is thus designed as a glove box.
Innerhalb des Behälters ist ein Druckluftanschluß und eine mit dem Druckluftanschluß verbundene Druckluftpistole installiert.A compressed air connection and a compressed air gun connected to the compressed air connection are installed inside the container.
In der Bodenplatte 4 des Behälters 3 ist ein Grobsieb 7 mit einer rechteckigen Außenkontur vorgesehen. Das Grobsieb weist eine Maschenweite von 1-10 mm auf.A coarse sieve 7 with a rectangular outer contour is provided in the base plate 4 of the container 3. The coarse sieve has a mesh size of 1-10 mm.
Der erste Teil 11 des Behälter 3 besteht aus Holz oder Plastik und die Haube besteht bevorzugt aus einem durchsichtigen Material, wie z.B. Plexiglas.The first part 11 of the container 3 is made of wood or plastic and the hood is preferably made of a transparent material, such as plexiglass.
Innerhalb des Metallrahmens 1 ist eine Siebmaschine 9 angeordnet. Die Siebmaschine 9 weist einen Einlaß 17 und einen ersten Auslaß 18 und einen zweiten Auslaß 19 auf. Mit dem Einlaß 17 ist ein Ende eines Trichters 10, welches einen ersten Querschnitt aufweist, verbunden. Ein zweites Ende des Trichters 10 weist einen zweiten Querschnitt auf, der größer als der erste Querschnitt ist. Eine Außenkontur des zweiten Querschnitts ist größer als die Außenkontur des Grobsiebs 7. Die Außenkontur ist rechteckig. Der Trichter 10 und die Siebmaschine 9 sind so positioniert, daß das zweite Ende des Trichters 10 direkt unterA screening machine 9 is arranged within the metal frame 1. The screening machine 9 has an inlet 17 and a first outlet 18 and a second outlet 19. One end of a funnel 10, which has a first cross-section, is connected to the inlet 17. A second end of the funnel 10 has a second cross-section that is larger than the first cross-section. An outer contour of the second cross-section is larger than the outer contour of the coarse screen 7. The outer contour is rectangular. The funnel 10 and the screening machine 9 are positioned so that the second end of the funnel 10 is directly below

dem Grobsieb 7 ist. Der Trichter 10 ist so an der Bodenplatte 4 befestigt, daß kein Pulverstaub zwischen dem Grobsieb 7 und dem Trichter 10 entweichen kann.the coarse sieve 7. The funnel 10 is attached to the base plate 4 in such a way that no powder dust can escape between the coarse sieve 7 and the funnel 10.
Unter dem ersten Auslaß 18 ist ein erster Auffangbehälter 20 und unter dem zweiten Auslaß 19 ist ein zweiter Auffangbehälter 21 angeordnet. Die Auffangbehälter 20, 21 sind jeweils so mit einem an einem Auslaß vorgesehenen Stutzen verbunden, daß kein Pulverstaub zwischen dem jeweiligen Auslaß 18, 19 und dem jeweiligen Auffangbehälter 20, 21 entweichen kann. Als Siebmaschine wird beispielsweise eine Wirbelstrom-Siebmaschine Typ E 240 der Firma AZO. verwendet. In der Siebmaschine 9 werden bevorzugt Siebe mit einer Maschengröße von 200 - 400 &mgr; verwendet. Für Kunststoffpulver werden bevorzugt ca. 200 &mgr;-Siebe und für Sand werden bevorzugt ca. 300 &mgr;-Siebe verwendet.A first collecting container 20 is arranged under the first outlet 18 and a second collecting container 21 is arranged under the second outlet 19. The collecting containers 20, 21 are each connected to a nozzle provided on an outlet in such a way that no powder dust can escape between the respective outlet 18, 19 and the respective collecting container 20, 21. For example, a whirlpool screening machine type E 240 from AZO is used as a screening machine. In the screening machine 9, sieves with a mesh size of 200 - 400 μ are preferably used. For plastic powder, approx. 200 μ sieves are preferred and for sand, approx. 300 μ sieves are preferred.
Im Betrieb wird die Haube 5 geöffnet. Dann wird ein aus einem pulverförmigen oder körnigen Materials hergestelltes Objekt, beispielsweise mittels Lasersintern, auf das Grobsieb 7 bzw. auf die Bodenplatte 4 gestellt. Danach wird die Haube 5 geschlossen. Nun wird das Objekt durch einen Bearbeiter nachbearbeitet. Der Bearbeiter schlüpft mit seinen Händen in die mit den Ausnehmungen 8 verbundenen Handschuhe und zerbricht einen mitgesinterten Behälter des Objekts. Das jetzt anfallende ungesinterte Pulver fällt durch das Grobsieb 7 und über den Trichter 10 in die Siebmaschine 9. Die Siebmaschine 9 siebt das Pulver und teilt es in ein Grobgut und ein Feingut auf. Das Grobgut wird in dem ersten Auffangbehälter 20 gesammelt und das Feingut wird in dem zweiten Auffangbehälter 21 gesammelt. Die Reste des zerbrochenen mitgesinterten Behälters des Objekts verbleiben in dem Behälter 3 oder werden falls sie das Grobsieb 7 passieren auch in der Siebmaschine 9 gesiebt.During operation, the hood 5 is opened. Then an object made from a powdery or granular material, for example by means of laser sintering, is placed on the coarse sieve 7 or on the base plate 4. The hood 5 is then closed. The object is then reworked by a processor. The processor slips his hands into the gloves connected to the recesses 8 and breaks a container that is sintered with the object. The now accruing unsintered powder falls through the coarse sieve 7 and over the funnel 10 into the sieving machine 9. The sieving machine 9 sieves the powder and divides it into coarse material and fine material. The coarse material is collected in the first collecting container 20 and the fine material is collected in the second collecting container 21. The remains of the broken sintered container of the object remain in the container 3 or, if they pass the coarse sieve 7, are also sieved in the sieving machine 9.
Zur besseren Reinigung kann das Objekt zusätzlich noch durch die Druckluftpistole mit Druckluft abgeblasen werden. Dann werden die im Behälter 3 verbliebenen Reste sowie das Objekt wieder aus dem Behälter 3 entfernt.For better cleaning, the object can also be blown off with compressed air using the compressed air gun. Then the residues remaining in container 3 and the object are removed from container 3.
Die Auffangbehälter 20, 21 mit dem Siebgut können nach Öffnen der Tür 2 aus dem verkleideten Metallrahmen 1 entnommen werden und das Feingut kann der Wiederverwendung zugeführt werden.The collecting containers 20, 21 with the screening material can be removed from the covered metal frame 1 after opening the door 2 and the fine material can be reused.
Durch den geschlossenen Behälter wird verhindert, daß bei der Nachbearbeitung entstehende Pulverstaubwolken aus dem Arbeitsbereich austreten können.The closed container prevents powder dust clouds that arise during post-processing from escaping from the work area.
Weiter weist die Einrichtung durch Verwendung der Siebmaschine eine erheblich größere Siebkapazität auf.Furthermore, the facility has a significantly larger screening capacity through the use of the screening machine.
In einer bevorzugten Ausführungsform ist eine Absaugung an dem Behälter 3 angeordnet. Die Absaugung kann beispielsweise eine anstatt oder neben der Druckluftpistole an dem Druckluftanschluß angeschlossene Venturidüse aufweisen. Damit wird der durch die Bearbeitung des Objektes entstehende feine Staub bzw. das Restpulver abgesaugt.In a preferred embodiment, an extraction system is arranged on the container 3. The extraction system can, for example, have a Venturi nozzle connected to the compressed air connection instead of or next to the compressed air gun. This extracts the fine dust or residual powder generated by processing the object.
