Description
Die Erfindung betrifft ein Verfahren zum Entgraten von Metallteilen mittels eines Hochdruck-Flüssigkeitsstrahles mit einem Druck > 400 bar, der aus einer Hochdruck-Düse austritt und auf das zu behandelnde Werkstück gerichtet wird, sowie eine Vorrichtung zur Durchführung des Verfahrens auf einer Metallbearbeitungsmaschine.The invention relates to a method for deburring metal parts by means of a High-pressure liquid jet with a pressure> 400 bar, which comes from a high-pressure nozzle emerges and is aimed at the workpiece to be treated, and an apparatus for performing the method on a metalworking machine.
Ein derartiges Verfahren und eine derartige Vorrichtung ist aus der DE 195 33 579 A1 bekannt. Bei diesem Stand der Technik wird der Hochdruck-Flüssigkeitsstrahl mit einem Hochdruck bis 500 bar unter Verwendung einer Ölemulsion gebildet. Derartige Ölemulsionen enthalten maximal 10 bis 15 % Öl in Wasser und Additiven vorzugsweise Emulgatoren, die die feinste Verteilung des Öls in dem Wasser begünstigen, mit dem sich Öl nicht vermischt. Dabei wird die Entgratungswirkung von dem spezifisch schwereren Wasser erreicht und üblicherweise wird bei den auf dem Markt befindlichen Anlagen mit maximal 350 bar gearbeitet. Dieser Hochdruck reicht bei dem vorwiegend aus Wasser bestehenden Hochdruck-Flüssigkeitsstrahl aus, um eine ausreichende Entgratungs- und Säuberungswirkung zu erreichen. Der Entgratungs- und Säuberungsprozess läßt sich, wie dieser Stand der Technik zeigt, leicht in den Herstellungsprozess des Werkstückes integrieren, wenn dieser in der Maschinenkammer durchgeführt wird und für den Hochdruck-Flüssigkeitsstrahl die schon für die Kühlung des zu bearbeitenden Werkstückes verwendete Bohr- oder Schneidölemulsion verwendet wird.Such a method and such a device is known from DE 195 33 579 A1 known. In this prior art, the high pressure liquid jet with a high pressure up to 500 bar using an oil emulsion educated. Such oil emulsions contain a maximum of 10 to 15% oil in Water and additives preferably emulsifiers, which have the finest distribution of the Favor oil in the water with which oil does not mix. Doing so achieves the deburring effect of the specifically heavier water and Usually, the maximum for the systems on the market 350 bar worked. This high pressure is mainly enough for water existing high-pressure liquid jet to ensure adequate deburring and to achieve cleaning effect. The deburring and cleaning process can, as this prior art shows, easily in the Integrate the manufacturing process of the workpiece when it is in the machine chamber is carried out and for the high pressure liquid jet already used for cooling the workpiece to be machined or cutting oil emulsion is used.
Nun werden aber immer mehr Metallbearbeitungsmaschinen eingesetzt, bei denen als Kühl- und Schmiermittel Schneidöle oder Bohröle verwendet werden, bei denen das Öl nicht in Emulsionen fein verteilt ist, sondern mit Additiven als Lösung vorliegt und demzufolge nur noch einen vernachlässigbaren Anteil an Wasser aufweist.Now, however, more and more metalworking machines are being used in which Cutting oils or drilling oils are used as coolants and lubricants which the oil is not finely divided in emulsions, but with additives as Solution is available and therefore only a negligible proportion Has water.
Es ist Aufgabe der Erfindung, eine Entgratungsvorrichtung der eingangs erwähnten Art so zu verbessern, dass auch Öle als Hochdruck-Flüssigkeitsstrahl mit ausreichend großer Entgratungs- und Säuberungswirkung ohne Gefahr eingesetzt werden können.The object of the invention is a deburring device of the type mentioned at the beginning Art to improve so that even oils as a high pressure liquid jet used with a sufficiently large deburring and cleaning effect without danger can be.

For the workpieces there is no additional for deburring and cleaning Handling effort required more. The manufacturing time of the parts can be thereby shorten considerably. The loosened burrs are in the metal working machine transported in the same way as the chips at the metal cutting Editing. All that is required is that the workpiece chamber is provided with a drain outlet that with the oil drain device the metalworking machine is connected or brought can.
Ist eine Zufuhr von Schutzgasen in die gekapselte Werkstückkammer vorgesehen, dann ist nach einer Ausgestaltung die Werkstückkammer mit einem Anschluß für eine von der Gasversorgung kommende Leitung versehen.If a supply of protective gases is provided in the encapsulated workpiece chamber, then, according to one embodiment, the workpiece chamber has a Provide connection for a line coming from the gas supply.
Das Öl aus dem Öltank der Metallbearbeitungsmaschine ist direkt oder über einen Ölzwischenbehälter der Hochdruck-Erzeugungseinrichtung zugeführt.The oil from the metal processing machine's oil tank is direct or over an intermediate oil tank of the high pressure generating device is supplied.

Das Medium mit einem Ölanteil von > 50% ist in einem Ölbehälter ÖV enthalten, aus dem es einer Hochdruck-Erzeugungseinrichtung HD-Q zuführbar ist, wie Fig. 1 zeigt. Das Medium wird in der Hochdruck-Erzeugungseinrichtung HD-Q auf einen Hochdruck > 400 bar gebracht, wobei in bekannter Weise Pumpen, pneumatische Regeleinrichtungen und dgl. verwendet werden. Das Medium wird dann einer Hochdruck-Düse HD-D zugeführt, die in einer gekapselten Werkstückkammer WK angeordnet und auf die zu entgratende Stelle des in die Werkstückkammer WK eingebrachten Werkstückes WS gerichtet ist. Der aus der Hochdruck-Düse HD-D austretende Hochdruck-Flüssigkeitsstrahl HD-FS ist sehr energiereich und bricht die Grate am Werkstück ab oder trägt sie ab. Das sich in der Werkstückkammer WK ansammelnde Medium fließt über einen Ablauf AL wieder zum Ölbehälter ÖV zurück.The medium with an oil content of> 50% is contained in an oil tank, from which it can be fed to a high-pressure generating device HD-Q is, as Fig. 1 shows.

The high-pressure liquid jet HD-FS emerging from the high-pressure nozzle HD-D is very energetic and breaks off or burrs on the workpiece. The medium that accumulates in the workpiece chamber WK flows through a Drain AL back to the oil tank ÖV.
Damit sich der Ölnebel in der Werkstückkammer WK nicht entzünden oder explodieren kann, wird zusätzlich Kohlenstoffdioxyd CO2 oder Stickstoff N in die Werkstückkammer WK eingeleitet und dies zumindest während des Entgratungsvorganges. Die Werkstückkammer WK hat dabei einen Anschluß AS für eine von einer entsprechenden Gasversorgung GV kommende Leitung. Ist diese zusätzliche Sicherheitsmaßnahme nicht erforderlich, dann kann der Anschluß AS auch verschlossen werden.So that the oil mist in the workpiece chamber WK does not ignite or can explode, additional carbon dioxide CO2 or nitrogen N in the workpiece chamber WK initiated and this at least during the deburring process. The workpiece chamber WK has a connection AS for a line coming from a corresponding gas supply GV. Is this additional security measure is not required, then the connection AS can also be closed.

Das Öl der Metallbearbeitungsmaschine MBM wird auch als Medium zum Entgraten verwendet. Es wird aus dem Öltank ÖT der Metallbearbeitungsmaschine MBM entnommen und direkt oder über einen Ölbehälter ÖV der Hochdruck-Erzeugungseinrichtung HD-Q zugeführt und auf einen Hochdruck > 400 bar gebracht. Die Metallbearbeitungsmaschine MBM weist mehrere Bearbeitungsstationen auf, in die das Werkstück nacheinander gebracht wird. Dabei sind jeder Bearbeitungsstation spezielle Werkzeuge für die darin vorzunehmend Bearbeitungsgänge zugeordnet. In bekannter Weise kann für die Bearbeitungsgänge Öl aus dem Öltank ÖT zur Kühlung und/oder Schmierung des Werkstückes WS und/oder der Werkzeuge verwendet werden. Das Öl wird mit den Spänen abtransportiert, von den Spänen befreit und wieder dem Öltank ÖT zugeführt. In der letzten Bearbeitungsstation im Zyklus des Herstellungsablaufes wird die Entgratung durchgeführt. Diese Bearbeitungsstation weist eine gekapselte Werkstückkammer WK auf, in die das in einer Werkstückaufnahme WA gehaltene und fertig bearbeitete Werkstück WS eingeführt wird. In der Werkstückkammer WK ist die Hochdruck-Düse HD-D angeordnet und auf die zu entgratende Stelle des Werkstückes WS ausgerichtet. Dabei kann die Ausrichtung und der Abstand der Hochdruck-Düse HD-D zum Werkstück verändert und eingestellt werden. Selbstverständlich können in der Werkstückkammer WK auch mehrere Hochdruck-Düsen HD-D angeordnet und auf ein und dasselbe Werkstück WS oder auf mehrere Werkstücke ausgerichtet sein.Fig. 2 now shows how the new deburring process in the manufacturing process the workpiece on a commercially available metal processing machine (turning and rotary probes with oil cooling and / or oil lubrication) can be integrated can. The oil of the metalworking machine MBM is also used as a medium used for deburring.
