Die US-PS 5 195 349 offenbart ein Werkzeug zum Massivumformen. Das Werkzeug weist eine obere und eine untere Matrize auf, der eine Schließvorrichtung zugeordnet ist. Des Weiteren weist das Werkzeug einen oberen Werkzeugteil auf, der fest mit der oberen Matrize verbunden ist. Der untere Werkzeugteil ist fest mit einem ortsfest gelagerten Pressentisch verbunden.The US-PS 5,195,349 discloses a tool for massive forming. The tool has an upper and a lower die, which has a closing device assigned. Furthermore, the tool has an upper tool part on, which is firmly connected to the upper die. The lower tool part is firmly connected to a fixedly mounted press table.
Bei einem solchen Werkzeug muss das Volumen des Rohlings weitgehend genau mit dem Innenvolumen des Werkzeugs übereinstimmen.at Such a tool must largely the volume of the blank exactly match the internal volume of the tool.
Es ist Aufgabe der vorliegenden Erfindung, eine Umformvorrichtung zu schaffen, bei der die Füllung der Form zuverlässig funktioniert.It Object of the present invention, a forming device to create at the filling the form reliable works.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Vorrichtung zum Umformen geschaffen wird, die wenigstens ein Werkzeugoberteil eine obere Matrize und eine untere Matrize und ein Werkzeugunterteil und eine erste Schließvorrichtung und eine zweite Schließvorrichtung umfaßt. Hierbei ist von Vorteil, daß die Schließkraft mittels der zwei Schließvorrichtungen, die unterschiedliche Schließkräfte aufweisen, an den benötigten Preßkraftverlauf, der für eine komplette Formfüllung des Werkzeugs notwendig ist, anpassbar ist.The The object is achieved in that a device is created for forming, the at least one tool shell a upper die and a lower die and a tool lower part and a first closing device and a second locking device includes. It is advantageous that the closing force by means of the two closing devices, have different closing forces, at the required Preßkraftverlauf, the for one complete mold filling of the tool is necessary, is customizable.
In einer erfindungsgemäßen Weiterbildung ist vorgesehen, daß der ersten und der zweiten Schließvorrichtung je ein Ringkolben mit Hülse zugeordnet ist.In a development of the invention is provided that the first and second locking device one ring piston each with sleeve assigned.
Eine weitere erfindungsgemäße Weiterbildung sieht vor, daß die Vorrichtung einen Druckring aufweist.A further development of the invention provides that the Device has a pressure ring.
Erfindungsgemäß ist in einer anderen Weiterbildung vorgesehen, daß die Vorrichtung wenigstens einen Stempel aufweist. Diese Stempel erweisen sich unter anderem als vorteilhaft im Falle des Auswerfens des fertigen Teiles aus dem Werkzeug.According to the invention is in another development provided that the device at least has a stamp. These stamps prove, among other things as advantageous in the case of ejection of the finished part the tool.
Weiter ist eine erfindungsgemäße Weiterbildung vorgesehen, bei der die Schließvorrichtung mit je einem Blasenspeicher kommuniziert. Es erweist sich als vorteilhaft, daß durch die Verwendung von unterschiedlichen Speichern unterschiedliche Schließkräfte realisierbar sind.Further is a development of the invention provided at the closing device each communicates with a bladder memory. It proves to be advantageous that by the use of different storage different closing forces feasible are.
In einer anderen erfindungsgemäßen Weiterbildung ist vorgesehen, daß die Vorrichtung einen Gegenstempel aufweist.In another embodiment of the invention is provided that the Device has a counter punch.
Eine erfindungsgemäße Weiterbildung der Erfindung sieht vor, daß die Vorrichtung wenigstens einen Auswerferstift aufweist.A inventive development the invention provides that the Device has at least one ejector pin.
Die Aufgabe wird erfindungsgemäß mittels einer Presse zum Umformen gelöst, die eine eingangs beschriebene Vorrichtung zum Umformen aufweist.The object is achieved according to the invention by means of a press for forming, which is an initially described device for forming has.
In einer erfindungsgemäßen Weiterbildung ist vorgesehen, daß die Presse wenigstens einen Stößel und wenigstens einen Pressentisch aufweist.In a development of the invention is provided that the Press at least a pestle and has at least one press table.
Eine andere erfindungsgemäße Weiterbildung sieht vor, daß die Presse wenigstens einen Stößelauswerferbolzen und wenigstens einen Tischauswerferbolzen aufweist.A other training according to the invention provides that the Press at least one plunger ejector pin and at least one Tischauswerferbolzen.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren zum Umformen gelöst, wobei eine Vorrichtung und/oder eine Presse zum Umformen, wie weiter oben beschrieben, zum Einsatz kommen. Von Vorteil ist hierbei, daß mittels dieses Verfahrens hergestellte Teile wegen der kompletten Formfüllung des Werkzeuges sehr präzise gefertigt werden.The The object is achieved by a Solved method of forming, wherein a device and / or a press for forming, as further described above, are used. The advantage here is that means This method produced parts because of the complete mold filling of the tool very precise be made.
