Abstract

The deforming process involves using a fluid (8) on the component (4). A cutting process follows after the deformation, in the same tool (1, 2). The cutting is carried out by means of fluid jet cutting, so that the same fluid can be used for both working processes. The fluid remaining in the tool can serve to damp the fluid jet (13).

Description

Die Erfindung bezieht sich auf ein Verfahren zum Umformen eines Bauteiles unter Mitwirkung eines auf das Bauteil einwirkenden Fluids, wobei im Zuge des Umformens im gleichen Werkzeug als weiterer Bearbeitungsvorgang ein Schneiden des Bauteiles erfolgt. Die Erfindung bezieht sich des weiteren auf ein geeignetes Werkzeug zur Durchführung des Verfahrens.The invention relates to a method for forming a component with the participation of a fluid acting on the component, whereby in the course of forming in the same tool as a further machining operation The component is cut. The invention further relates to a suitable tool for performing the method.

Die erwähnte Verfahrensweise zum Bearbeiten eines Werkstückes ist be­ kannter Stand der Technik, wie dies beispielsweise aus der EP 0 484 789 B1 und der DE 195 06 067 C1 hervorgeht. Beide Dokumente beziehen sich auf die Technologie des Innenhochdruckumformens und nutzen für das Aus­ schneiden eines Ausschnittes aus der Wandung eines als Hohlkörper aus­ gebildeten Bauteiles während oder unmittelbar nach dessen Umformung die Wirkung des Fluids und einen entsprechend gestalteten Stempel als Schneidwerkzeug oder sehen geeignet ausgebildete Schneidkanten an Werkzeugausnehmungen vor.The above-mentioned procedure for machining a workpiece is known prior art, such as this from EP 0 484 789 B1 and DE 195 06 067 C1 emerges. Both documents refer on the technology of hydroforming and use it for the end cut out a section of the wall as a hollow body formed component during or immediately after its forming Effect of the fluid and a stamp designed accordingly Cutting tool or look at suitably trained cutting edges Tool recesses.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Verfahrensweise zum Umformen und Schneiden eines Bauteiles unter Mitwirkung eines Fluids derart zu gestalten, daß das Fluid weitergehende Funktionen erfüllen kann.The invention is based, the known procedure for forming and cutting a component with the help of a fluid to be designed in such a way that the fluid can perform further functions.

Die erfindungsgemäße Lösung ergibt sich dadurch, daß nach den kenn­ zeichnenden Merkmalen des Patentanspruches 1 verfahren wird.The solution according to the invention results from the fact that according to the drawing features of claim 1 is proceeded.

Sonach wird der Schneidvorgang unter Einsatz von Fluidstrahlen hoher Ge­ schwindigkeit vorgenommen. Diese Technologie ist an sich im Stand der Technik hinlänglich bekannt, vgl. DE 196 03 933 A1 bzw. internationale Pa­ tentklassifikation B 24 C 5/02 (Strahlpistolen, z. B. zum Erzeugen material­ abtragender Fluidstrahlen hoher Geschwindigkeit für das Schneiden von Werkstoffen) bzw. B 26 F 1/26 (Perforieren durch nichtmechanische Mittel, z. B. durch einen Flüssigkeits- oder Gasstrahl). Der wesentliche Vorteil bei der Anwendung gerade dieser Schneid-Technologie ist, daß das bei der Umformung des Bauteiles mitwirkende Fluid als Mittel zum Erzeugen und/oder Auffangen bzw. Dämpfen/Abbremsen des Fluidstrahles dienen kann. Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind mit den Unteransprüchen beansprucht.Then the cutting process is carried out using fluid jets of high Ge speed made. This technology is in itself state of the art Technology well known, cf. DE 196 03 933 A1 or international Pa tent classification B 24 C 5/02 (blasting guns, e.g. for producing material abrasive fluid jets of high speed for cutting Materials) or B 26 F 1/26 (perforation by non-mechanical means, e.g. B. by a liquid or gas jet). The main advantage at  The application of this cutting technology is that it is used in the Reshaping of the component fluid as a means of generating and / or serve to collect or dampen / brake the fluid jet can. Advantageous further developments and refinements of the invention are claimed with the subclaims.

Besonders vorteilhaft ist die Erfindung gemäß Patentanspruch 2 beim hy­ dromechanischen Tiefziehen einzusetzen, eine als solche ebenfalls hinläng­ lich bekannte Technologie zum Umformen platinenförmiger Bauteile (vgl. "Das hydromechanische Ziehverfahren" in Blech Nr. 9/1963, Seiten 573 bis 578). In gleicher Weise läßt sich die Erfindung natürlich auch beim Innen­ hochdruckumformen von Bauteilen anwenden, wie dies in Patentanspruch 3 angegeben ist.The invention according to claim 2 is particularly advantageous in the hy to use dromechanical deep drawing, one as such is also sufficient Lich known technology for forming sheet-like components (cf. "The hydromechanical drawing process" in sheet No. 9/1963, pages 573 to 578). In the same way, the invention can of course also be used inside Apply high pressure forming of components, as in claim 3 is specified.

Stets ist es sinnvoll, daß das beim Umformen mitwirkende Fluid so lange im entsprechenden Werkzeugteil bzw. im Bauteilhohlraum verbleibt, bis der Schneidvorgang abgeschlossen ist. Natürlich wäre auch denkbar, vor dem Schneidvorgang ein Fluidwechsel/Austausch vorzusehen.It always makes sense that the fluid that is involved in the forming process lasts for so long corresponding tool part or in the component cavity until the Cutting process is completed. Of course, it would also be conceivable before Cutting process to provide a fluid change / exchange.

Ein besonders geeignetes Werkzeug zur Durchführung des Verfahrens ist mit Patentanspruch 6 beansprucht.A particularly suitable tool for performing the method is claimed with claim 6.

Unter "Schneiden" ist auch ein Lochen, Trennen, Perforieren, Prägen, Be­ schriften, Markieren usw. zu verstehen. Das erfindungsgemäße Verfahren ist vorteilhaft beispielsweise anwendbar beim Umformen und Schneiden von Bauteilen aus Stahl, Edelstahl, Aluminiumlegierungen, Magnesiumlegierun­ gen usw."Cutting" also includes punching, separating, perforating, embossing, loading understand writings, marking, etc. The method according to the invention is can be used advantageously, for example, when shaping and cutting Components made of steel, stainless steel, aluminum alloys, magnesium alloy gene etc.

Ein Ausführungsbeispiel ist in Fig. 1 schematisch dargestellt, welche im we­ sentlichen das hydromechanische Ziehverfahren veranschaulicht. Dabei wir­ ken ein Unter- und ein Oberwerkzeug 1, 2 zusammen, wobei eine Ausneh­ mung 3 des Unterwerkzeuges 1 zusammen mit einer darauf aufliegenden Platine, die in der Darstellung bereits zu einem Bauteil 4 umgeformt ist, ei­ nen Druckraum einschließen. Ein entsprechend geformter Stempel 5 des vertikal beweglichen (Doppelpfeil 6) Oberwerkzeuges 2 taucht in die Aus­ nehmung 3 des Unterwerkzeuges 1 ein und bewerkstelligt die Umformung. Das Bauteil 4 wird in bekannter Weise während des Umformens randseitig von Niederhaltern 7 gehalten. Zulauf und Ablauf eines Fluids 8 sowie auch der Druck desselben vor, während und nach dem Umformvorgang sind durch entsprechende Zulauf- bzw. Ablaufleitungen 9, 10 gewährleistet, die unter Zwischenschaltung einer Pumpe 17 von einem Vorratsbehälter 18 ausgehen bzw. in diesen münden. Als Fluid 8 könnte beispielsweise dienen:
Wasser, Öl, Wasser-Öl-Emulsion in geeigneter Zusammensetzung sowie andere geeignete Emulsionsgemische.An embodiment is shown schematically in Fig. 1, which essentially illustrates the hydromechanical drawing process. We ken a lower and an upper tool 1 , 2 together, a Ausneh mung 3 of the lower tool 1 together with a board lying thereon, which is already formed into a component 4 in the illustration, include a pressure chamber. A correspondingly shaped stamp 5 of the vertically movable (double arrow 6 ) upper tool 2 plunges into the recess 3 from the lower tool 1 and accomplishes the forming. The component 4 is held in a known manner on the edge side by hold-down devices 7 during the forming. The inflow and outflow of a fluid 8 as well as the pressure of the same before, during and after the shaping process are ensured by corresponding inflow and outflow lines 9 , 10 which, with the interposition of a pump 17, emanate from a reservoir 18 or flow into the latter. The following could serve as fluid 8 :
Water, oil, water-oil emulsion in a suitable composition and other suitable emulsion mixtures.

Nach dem Umformen und anschließenden Anheben des Oberwerkzeuges 2 gelangt ein Gelenkarmroboter 11 mit endseitig angeordneter Strahlpistole 12 in den Bereich des noch im Unterwerkzeug 1 eingelegten Bauteiles 4, um mittels Fluidstrahl 13 einen Durchbruch 14 beliebiger Geometrie zu erzeu­ gen. Nach Durchdringen des Bauteiles 4 gelangt ein austretender Fluidstrahl 15 in den Einflußbereich des Fluids 8 und wird von diesem abgebremst.After forming and subsequent raising of the upper tool 2, an articulated arm 11 engages with its end arranged blasting gun 12 in the area of the inserted yet in the lower tool 1 component 4 to gene by means of fluid jet 13 an opening 14 of any desired geometry to erzeu. Passes after penetration of the component 4 a emerging fluid jet 15 in the area of influence of the fluid 8 and is braked by the latter.

Damit nach dem Anheben des Oberwerkzeuges 2 und außer Eingriff bringen der Niederhalter 7 keine unerwünschte Positionsveränderung des Bauteiles 4 erfolgen kann sind im Unterwerkzeug 1 an geeigneter Stelle zusätzliche Bauteilhalter 16, z. B. Magnete, Stifte, Sauger usw. angeordnet.So that after lifting the upper tool 2 and disengaging the hold-down device 7 no undesired change in position of the component 4 can take place in the lower tool 1 at a suitable point additional component holder 16 , z. B. magnets, pens, suction cups, etc. arranged.

Das Fluid für den Schneidvorgang kann beispielsweise Wasser, Wasser mit Zusätzen und Zusatzwirkstoffen (z. B. Abrasivsand für härtere Bauteil-Werk­ stoffe) usw. sein. Es ist zweckmäßig, wenn der Fluidstrahl 13 und das Fluid 8 für den Umformprozeß die gleiche Zusammensetzung besitzen, also iden­ tisch sind, so daß an die Strahlpistole 12 eine Versorgungsleitung 19 ange­ schlossen werden kann, die über eine Druckpumpe 20 in den Vorratsbehäl­ ter 18 mündet.The fluid for the cutting process can be, for example, water, water with additives and additional active substances (e.g. abrasive sand for harder component materials), etc. It is expedient if the fluid jet 13 and the fluid 8 for the forming process have the same composition, that is, they are identical, so that a supply line 19 can be connected to the jet gun 12, which opens out via a pressure pump 20 into the reservoir 18 ter 18 .

Anstelle eines Gelenkarmroboters 11 ist natürlich auch denkbar, die Strahl­ pistole 12 manuell oder mittels anderweitig geeigneter Vorrichtungen zu handhaben. Denkbar wäre auch, die Strahlpistole 12 an geeigneter Stelle in das Oberwerkzeug 2 zu integrieren.Instead of an articulated arm robot 11, it is of course also conceivable to handle the jet gun 12 manually or by means of other suitable devices. It would also be conceivable to integrate the blasting gun 12 into the upper tool 2 at a suitable point.

Wird die erfindungsgemäße Verfahrensweise beim Umformprozeß-Innen­ hochdruckumformen eingesetzt, so ist eine analoge Vorgehensweise an­ gezeigt. Die Strahlpistole 12 bzw. der Fluidstrahl 13 wird von außen nach innen in den mit Wirkmedium gefüllten Hohlraum des Bauteiles gerichtet, um z. B. einen Durchbruch in die Bauteilwandung einzubringen.If the procedure according to the invention is used for forming high-pressure inside, an analogous procedure is shown. The jet gun 12 or the fluid jet 13 is directed from the outside inwards into the cavity of the component filled with active medium in order to, for. B. bring a breakthrough in the component wall.
