Description
Verfahren und Vorrichtung zur Herstellung eines Hohlkörpers mit einer Aushalsung durch Explosiv-Verformung 7 Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines Hohlkörpers mit einer Aushalsung durch Explosiv-Verformung, bei dem eine Ronde in einer Matrize zu einem Hohlkörper verformt wird. Method and device for producing a hollow body with a Collaring by explosive deformation 7 The invention relates to a method and a device for the production of a hollow body with a neck by explosive deformation, in which a round blank is deformed into a hollow body in a die.
Bekannt ist, daß man mit Explosionsenergie oeffnungen mit und ohne Gegenwerkzeug stanzen kann. Bekannt ist, daß in einem. gesonderten Arbeitsgang durch vorheriges Einbringen -der Öffnung entsprechend der Abwicklung dann mittels Sprengstoff die Aushalsung in einer Matrize ausgeformt wird.It is known that explosive energy can be used to create openings with and without Can punch counter tool. It is known that in one. separate operation prior introduction of the opening according to the development then by means of explosives the neck is formed in a die.
Aufgabe der Erfindung ist es, ein vereinfachtes Verfahren und eine Vorrichtung zu schaffen, bei-dem durch Explosivumformung von Blechen zu Hohlkörpern in einem Arbeitsgang bei entsprechender Einrichtung in der Matrize Aushalsungen eingeformt werden können.The object of the invention is to provide a simplified method and a To create a device in which by explosive deformation of metal sheets to form hollow bodies in one operation with the appropriate equipment in the die can be molded.
Das Verfahren nach der Erfindung besteht darin, daß die Verformung des Hohlkörpers und die Aushalsung in einem Arbeitsgang vorgenommen werden, in dem mit dem Eindrücken der Ronde in die Matrize gleichzeitig eine Öffnung in die Ronde gestanzt und eine Ausformung der Aushalsung durchgefUhrt wird0 In der Zeichnung ist das erfindungsgemäße Verfahren näher erläutert. Es wird ein Schnitt durch eine Verformungavorrichtung gezeigt.The method according to the invention is that the deformation of the hollow body and the necking are carried out in one operation, in which When the round blank is pressed into the die, an opening is created in the blank at the same time punched and a shaping of the neck is carried out 0 in the drawing the method according to the invention is explained in more detail. There will be a cut through one Deformation device shown.
Die Ronde 1 befindet sich vor der Verformuiig auf der Matrize 2 und wird durch den Niederhalter 3 festgespannt. Die Matrize 2 ist mit einer Vakuumleitung 4 verbunden. Die Sprengstoffladung 5 befindet sich oberhalb der Ronde 1. Die Matrize 2 hat eine Vertiefung 6, in der sich ein Stanzwerkzeug 7 befindet.The round blank 1 is located on the die 2 and in front of the deformation is clamped by the hold-down device 3. The die 2 is provided with a vacuum line 4 connected. The explosive charge 5 is located above the round blank 1. The die 2 has a recess 6 in which a punch 7 is located.
Das umzuforniende Blech 1 wird auf die Matrize 2 aufgelegt. Nach Anbringen der Sprengstoffladung 5 wird die Matrize in einen Wasserbehälter abgesenkt. Bei Zündung des Sprengstoffes wird die freiwerdende Energie, übertragen durch das Wasser, zur Umformung des Bleches 1 in die der in der Matrize 2 enthaltenen Kontur ausgenutzt.The sheet metal 1 to be reworked is placed on the die 2. After attaching the explosive charge 5, the die is lowered into a water container. at Ignition of the explosive is the released energy, transmitted through the water, used for reshaping the sheet 1 into the contour contained in the die 2.
Sind Aushalsungen in runder, ovaler oder eckiger Ausführung in dem zu formenden Teil vorgesehen, so ist in der Matrizenwandung ein Stanz- und Aushalswerkzeug 7 eingesetzt.Are round, oval or square shaped collars in the Part to be formed is provided, a punching and necking tool is provided in the die wall 7 used.
Bei der Explosivuraformung schlägt das umzuformende Blech zur Erzielung einer exakten Formung mit hoher Geschwindigkeit in der Größenordnung von 100 - 200 m/sec auf die Matrizenwandung auf. Infolgedessen wird beim Auftreffen des Bleches 1 auf das in der Matrizenwandung eingebrachte Stanzwerkzeug 7 die Ordnung entsprechend der Abwicklung der Aushalsung herausgetrennt und die kinetische Energie ist auch noch ausreichend, die Aushalsung 8 auszuformen. Bei entsprechender Ausführung des Stanz- und Aushalswerkzeuges ist keine weitere Bearbeitung erforderlich.During the explosive forming, the sheet metal to be formed strikes to achieve this precise molding at high speed on the order of 100-200 m / sec on the die wall. As a result, when it hits the sheet 1 on the punching tool 7 introduced into the die wall accordingly the development of the neck cut out and the kinetic energy is also still sufficient to form the collar 8. With the appropriate execution of the No further processing is required for the punching and necking tool.
