Description

Die zum Pressen großer Blechteile oder zum Schmieden eingerichteten Pressen arbeiten zum Teil mit sehr hohen Drücken und haben deshalb im Laufe der Entwicklung Ausmaße und Formen angenommen, die zu außerordentlich großen Gewichten und damit zu entsprechenden hohen Gestehungskosten sowie zu einem großen Platzbedarf geführt haben. Um einerseits die sich immer mehr steigernden Preßkräfte, die bereits einen Wert von 75 0001 überschreiten, in einer tragbaren Form aufzunehmen, andererseits aber die Maße und Gewichte der Preßanlagen möglichst klein zu halten, ist es bereits bekannt, Hochdruckpressen in Tunnelform zu bauen. Bei derartigen Pressen wird das Werkstück durch einen Preßtisch verformt, der mit Hilfe von einem zugeordneten, aufblähbaren Gummisack gegen das Werkstück gepreßt wird. Bei diesen Pressen wirkt der mit einer Flüssigkeit hohen Druckes beaufschlagte Gummisack unter dem Preßtisch nur von einer Seite her auf das Werkstück, meist eine Blechtafel, so daß nur eine Blechverformung möglich ist.Some of the presses set up for pressing large sheet metal parts or forging work with very high pressures and have therefore assumed dimensions and shapes in the course of development, the extraordinarily large weights and thus correspondingly high production costs as well as have resulted in a large space requirement. On the one hand, the increasingly increasing pressing forces that already exceed a value of 75,0001 to be recorded in a portable form, but on the other hand To keep the dimensions and weights of the press systems as small as possible, it is already known, high-pressure presses to build in tunnel form. In such presses, the workpiece is passed through a press table deformed, which is pressed against the workpiece with the help of an associated, inflatable rubber bag will. In these presses, the rubber bag, which is subjected to a high pressure liquid, acts under the press table only from one side onto the workpiece, usually a sheet metal, so that only a sheet metal deformation is possible.

Die Erfindung bezieht sich auf eine hydraulische Hochdruckpresse mit zwei als solche starren, Werkzeuge tragenden Pressentischen. Erfindungsgemäß ist jedem der beiden Pressentische je ein Gummisack zugeordnet, wobei die den Gummisäcken zugewandten Oberflächen der Pressentische gewölbt ausgebildet und die beiden Pressentische in einem an sich bekannten rohrförmigen Tunnelgehäuse untergebracht sind. Bei kleinstem Gewicht der Presse ist eine sehr hohe Druckleistung durch die besondere Form der den Gummikissen zugewandten Oberflächen möglich, wobei zwei gegeneinander arbeitende Pressetische verwendet werden.The invention relates to a hydraulic high-pressure press with two, as such, rigid tools load-bearing press tables. According to the invention, each of the two press tables is a rubber bag assigned, wherein the rubber bags facing surfaces of the press tables are arched and the two press tables housed in a tubular tunnel housing known per se are. With the smallest weight of the press, a very high printing performance is possible thanks to the special shape of the Surfaces facing rubber cushions are possible, whereby two press tables working against one another are used will.

Dadurch wird erreicht, daß außer der erwähnten Material verformung, z. B. durch Ziehen des Werkstückes, auch Schmiedearbeiten auf der Hochdruckpresse vorgenommen werden können, d. h. daß das Werkstück zwischen zwei harten Werkzeugen verformt werden kann.This ensures that, in addition to the material mentioned, deformation, z. B. by pulling the workpiece, blacksmithing work can also be carried out on the high-pressure press, d. H. that this Workpiece can be deformed between two hard tools.

Die erfindungsgemäße Presse vereinigt somit in sich die Mittel und Einrichtungen zur Durchführung folgender Arbeitsprozesse: Sie kann wahlweise zum Schmieden, zum Blechpressen mit Hilfe von Matrize und Patrize oder zum Blechverformen mit Hilfe eines Gummikissens verwendet werden.The press according to the invention thus combines the means and devices for implementation the following work processes: It can be used either for forging or for sheet metal pressing with the aid of a die and male molds or for sheet metal forming with the help of a rubber pad.

In der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt.The subject of the invention is shown schematically in the drawing.

In dem rohrförmigen Tunnelgehäuse 1 sind die Pressentische 2 und 3 untergebracht, die sich entlang der Führungswände 4 abhängig oder unabhängig voneinander in lotrechter Richtung gegeneinander bewegen können. Zwischen dem Tunnelgehäuse 1 und den entsprechend gewölbten Flächen 5 und 6 der Pressen-Hydraulisctie HochdruckpresseIn the tubular tunnel housing 1, the press tables 2 and 3 are housed, which run along of the guide walls 4 depending on or independently of each other in the vertical direction against each other can. Between the tunnel housing 1 and the correspondingly curved surfaces 5 and 6 of the press hydraulic system High pressure press

tische 2 und 3 liegen die Gummisäcke 7 und 8, die über Rohrleitungen mit einem nicht dargestellten Druckflüssigkeitsvorratsbehälter in Verbindung stehen. In diesen Gummisäcken 7 und 8 wird der Preßdruck durch Beaufschlagung mit einer Flüssigkeit hohen Druckes erzeugt. Da nun die den Gummisäcken zugewandte Oberfläche 5 und 6 der Pressentische2 und 3 gewölbt ist, somit größer ist als die als Werkzeug nutzbare Fläche der Pressentische, kann eine wesentlich größere Preßkraft erzeugt werden, als dies bei den bisher bekannten Pressen möglich war, ohne daß die Abmessungen und Gewichte der Preßanlage in untragbarer Weise gesteigert werden.tables 2 and 3 are the rubber bags 7 and 8, which are pipelines with a not shown Hydraulic fluid reservoir are in communication. In these rubber bags 7 and 8, the pressure is applied generated by the application of a high pressure liquid. Since now the one facing the rubber bags Surface 5 and 6 of the press tables 2 and 3 is curved, thus larger than the tool usable area of the press table, a much greater pressing force can be generated than with the previously known presses was possible without the dimensions and weights of the press system becoming unacceptable Way to be increased.

Die Rückführung der Pressentische 2 und 3 nach dem Arbeitsgang erfolgt entweder durch ihr Eigengewicht bei Pressen, bei denen sich die Pressentische in lotrechter Richtung zueinander bewegen, oder durch besondere hydraulisch gesteuerte Einrichtungen.The return of the press tables 2 and 3 after the work cycle is done either by their own weight in presses in which the press tables move in a perpendicular direction to each other, or through special hydraulically controlled devices.
