Description
Vorrichtung zum hydraulischen Tiefziehen Zusatz zum Patent: 1240 801 Gegenstand des Hauptpatentes ist eine Vorrichtung zum hydraulischen Tiefziehen, insbesondere von Blech, mit einem mit Flüssigkeit gefüllten Druckbehälter, einem Ziehstempel, über den beim Eindringen in den Behälter das herzustellende Ziehteil durch den Druck der Flüssigkeit geformt wird, einem das auf den Rand des Druckbehälters aufgelegte Ziehteil belastenden, jedoch ein Nachgleiten ermöglichenden Niederhalter und einen durch die Blechauflagefläche des Druckbehälterrandes zusammen mit dem Ziehteil gebildeten, dichten Behälterabschluß, wobei die Flüssigkeit zwischen dem Ziehteil und dem ihm zugekehrten Behälterrand bis zu diesem als Druckpolster herangeführt ist.Device for hydraulic deep drawing Addendum to patent: 1 240 801 The subject of the main patent is a device for hydraulic deep drawing, in particular of sheet metal, with a pressure vessel filled with liquid, a drawing punch, through which the drawn part to be produced when penetrating the container is caused by the pressure of the liquid is formed, a loading on the drawn part placed on the edge of the pressure vessel, but a sliding allowing hold-down and a tight container closure formed by the sheet metal support surface of the pressure vessel edge together with the drawn part, the liquid between the drawn part and the container edge facing it up to this as Pressure pad is brought up.
Voraussetzung für den Betrieb einer Vorrichtung nach dem Hauptpatent ist die Füllung des Druckbehälters derart, daß zwischen diesem und dem Ziehteil, d. h. der aufgelegten Platine, keine Luftblasen vorhanden sind. Sofern das Ziehteil einen ebenen Flansch hat, d. h. alle Randteile in ein und derselben horizontalen Ebene liegen, bereitet die Füllung des Druckbehälters keine Schwierigkeiten. Werden je- doch Teile gezogen, deren Flansch nicht in einer Ebene liegt, der also uneben ist, so muß Vorsorge getroffen werden, daß der Druckbehälter blasenfrei gefüllt werden kann.A prerequisite for the operation of a device according to the main patent is the filling of the pressure vessel in such a way that between this and the drawn part, d. H. the printed circuit board, there are no air bubbles. If the drawn part has a flat flange, i. H. all edge parts lie in one and the same horizontal plane, the filling of the pressure vessel does not cause any difficulties. However, if parts are pulled whose flange is not in one plane, which is therefore uneven, then precautions must be taken to ensure that the pressure vessel can be filled without bubbles.
In Weiterbildung der Erfindung nach dem Hauptpatent wird für Ziehteile mit unebenem Flansch vorgeschlagen, im Druckbehälter im höchstgelegenen Bereich der Randfläche Entlüftungsventile od. dgl. anzuordnen, durch die nach dem Auflegen des Ziehteiles und Anlegen des Niederhalters der geschlossene Druckbehälter zum Füllen entlüftet werden kann.In a further development of the invention according to the main patent is for drawn parts Suggested with an uneven flange, in the pressure vessel in the highest area the edge surface vent valves od. The like. To be arranged through the after placing of the drawn part and applying the hold-down device to the closed pressure vessel Filling can be vented.
Das Füllen des durch das Ziehteil und den angelegten Niederhalter geschlossenen Druckbehälters kann mit Hilfe eines in den Druckbehälter oder in einen damit verbundenen Behälter eintauchenden Kolbens erfolgen.The filling of the through the drawn part and the applied hold-down closed pressure vessel can with the help of a in the pressure vessel or in a associated container plunging piston take place.
Für die Vorrichtung nach der Erfindung können sowohl einfach als auch mehrfach wirkende Pressen eingesetzt werden. Bei einfach wirkenden Pressen muß der Niederhalter gegenüber dem Ziehstempel einen entsprechenden federbelasteten Vorlauf haben. Die Steuerung des Druckes im Druckbehälter kann in Abhängigkeit von der Stellung des Ziehstempels erfolgen.For the device according to the invention can be both simple and multiple acting presses are used. In the case of single-acting presses, the Hold-down a corresponding spring-loaded lead opposite the drawing punch to have. The pressure in the pressure vessel can be controlled depending on the position of the drawing punch.
Die Erfindung wird an Hand der Zeichnung erläutert, die die Ziehvorrichtung im Querschnitt in verschiedenen Stadien des Ziehvorganges zeigt, und zwar F i g. 1 in geöffnetem Zustand, F i g. 2 mit angelegtem Niederhalter, F i g. 3 im entlüfteten Zustand, also mit gefülltem Druckbehälter, und F i g. 4 mit eingedrücktem Ziehstempel nach dem Formelvorgang.The invention is explained with reference to the drawing, which shows the pulling device in cross section in different stages of the pulling process, namely F i g. 1 in the open state, FIG. 2 with hold-down device applied, FIG . 3 in the vented state, that is to say with a filled pressure vessel, and F i g. 4 with the drawing punch pressed in after the formula process.
Die Ziehvorrichtung besitzt ein Unterteil 1, das die Wandung des Druckbehälters 2 bildet, der mit einem Zuflußventil 31 und einem Abflußventil 32 versehen ist. Zur Formung der durch den Niederhalter 8 gegen die Randfläche 33 des Unterteiles 1 gedrückten Platine 9 dient ein Ziehstempel 7. The pulling device has a lower part 1, which forms the wall of the pressure vessel 2, which is provided with an inflow valve 31 and an outflow valve 32 . A drawing punch 7 is used to shape the blank 9 pressed by the hold-down device 8 against the edge surface 33 of the lower part 1.
Mit der Vorrichtung nach der Erfindung ergibt sich folgender Arbeitsablauf.The following workflow results with the device according to the invention.
Die Platine 9 wird zunächst auf die Ziehwulst 24 des Unterteiles 1 aufgelegt und in ihrer Lage durch die Einlegestifte 23 gehaltert (F i g. 1). The circuit board 9 is first placed on the drawn bead 24 of the lower part 1 and held in its position by the insert pins 23 (FIG. 1).
Die Ziehvorrichtung wird nun durch den Niederhalter 8 geschlossen (F i g. 2). Dabei legt sich die Ziehwulst 24 in entsprechende Ausnehmungen 35 der Unterfläche 34 des Niederhalters 8. Durch das Aufsetzen des Niederhalters 8 werden die Randpartien der Platine 9 entsprechend der Randfläche 33 des Unterteiles 1 verformt.The pulling device is now closed by the hold-down device 8 ( FIG. 2). The pulling bead 24 lies in corresponding recesses 35 of the lower surface 34 of the hold-down device 8. By placing the hold-down device 8 , the edge portions of the board 9 are deformed in accordance with the edge surface 33 of the lower part 1.
Sobald der Niederhalter 8 allseitig aufliegt und damit die Platine gegen die Dichtung 43 gepreßt ist, kann der Druckbehälter 2 vollständig gefüllt werden. Dies erfolgt durch Verschieben des Kolbens 27 in Richtung des Pfeiles 36 unter gleichzeitigem öffnen des Ventils 25 (F i g. 3). Nunmehr ist auch der Raum zwischen dem niedrigsten Punkt 37 und dem höchsten Punkt 38 der Randfläche 33 des Unterteiles 1 mit Flüssigkeit gefüllt. Das Ventil 25 wird nuninehr wieder geschlossen, und das eigentliche Ziehen beginnt durch das Eindrücken des Ziehsterapels 7. Der Ziehstempel 7 drückt die Platine9 nach unten, wobei die Druckflüssigkeit als Matrize wirkt und die Platine über die Begrenzungsfläche 39 des ZiehstempeIs 7 formt. Am Ende des Ziehvorganges (F i g. 4) ist aus der Platine 9 das Ziehteil 41 mit dem gewölbten Flansch 42 geformt.As soon as the hold-down device 8 rests on all sides and the board is thus pressed against the seal 43, the pressure vessel 2 can be completely filled. This is done by moving the piston 27 in the direction of the arrow 36 while opening the valve 25 at the same time ( FIG. 3). The space between the lowest point 37 and the highest point 38 of the edge surface 33 of the lower part 1 is now also filled with liquid. The valve 25 is now closed again, and the actual drawing begins by pressing in the drawing stack 7. The drawing punch 7 pushes the blank 9 downward, the pressure fluid acting as a die and forming the blank over the boundary surface 39 of the drawing die 7. At the end of the drawing process (FIG . 4), the drawn part 41 with the curved flange 42 is formed from the blank 9.
Mit einer Vorrichtung nach der Erfindung lassen sich in der beschriebenen Weise Ziehteile mit unebenem Flansch, z. B. Kotflügel für Kraftwagen, in dem meisten Fällen mit nur einem einzigen Zug formen.With a device according to the invention can be described in the Way drawn parts with uneven flange, e.g. B. fenders for motor vehicles, in most Shape cases with just one pull.
