KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine weitere Ausbildung der in dem Patent 136634 gekennzeichneten Einrichtung und dient ebenso wie diese dazu, ein gleichmäßiges Aufspannen des Arbeitsstückes bei Ziehpressen usw. so zu gewährleisten, daß dasselbe an seinen Rändern überall aufliegt, was man bei den bisher bekannten Einrichtungen mittels eines kugelförmigen Einlegeringes usw. nur mangelhaft erreichen konnte. Ebenso wie nach dem Patent 136634 wird der Blechhalter einem Flüssigkeitsdruck ausgesetzt. Während derselbe jedoch dort auf einer Reihe von in einem mit Flüssigkeit gefüllten Zylindern angeordneten Kolben ruhte, ist hier statt mehrerer Zylinder eine einzige Aussparung im Tisch oder in der Blechhalteführung bezw. dem Blechhalter angebracht, in welcher ein mit Flüssigkeit oder Gas gefüllter Schlauch sich befindet.The present invention relates to a further embodiment of that characterized in patent 136634 Device and, like this, serves to ensure an even clamping of the workpiece in drawing presses, etc. that the same lies everywhere at its edges, what is known so far with the Achieve facilities by means of a spherical insert ring, etc. only inadequately could. As in the 136634 patent, the blank holder is subjected to liquid pressure exposed. During the same, however, there on a number of in one filled with liquid Pistons arranged in the cylinders are at rest, there is a single cylinder instead of several cylinders Recess in the table or in the sheet metal holding guide respectively. attached to the sheet metal holder, in which is a tube filled with liquid or gas.
Eine derartige Einrichtung ist in Fig. 1 und 2 der beiliegenden Zeichnung dargestellt, wobei Fig. ι die Anordnung der Aussparung im Blechhalter, Fig. 2 im Tisch zeigt.Such a device is shown in Figs the accompanying drawing, Fig. ι the arrangement of the recess in the sheet metal holder, Fig. 2 shows in the table.
Die Wirkungsweise ist folgende:The mode of action is as follows:
Die zu bearbeitende Blechplatte 3 wird zwischen Blechhalter 5 und Matrize 4 festgespannt. Der hierzu erforderliche Druck wird auf den Ring oder die Platte 2 und damit auf den mit ihr in Berührung befindlichen, mit Flüssigkeit oder Gas gefüllten Behälter 1 übertragen. Das in 1 enthaltene Gas oder Wasser wird infolgedessen dahin gedrängt, wo noch kein Druck stattgefunden hat, d. h. der Ring oder die Platte stellt sich selbsttätig ein; die Blechscheibe wird überall mit gleich großem Druck festgehalten und die Werkzeuge passen sich allen Unebenheiten des zu bearbeitenden Arbeitsstückes an.The sheet metal plate 3 to be processed is clamped between the sheet metal holder 5 and the die 4. The pressure required for this is on the ring or the plate 2 and thus on transferred to the container 1 which is in contact with it and filled with liquid or gas. The gas or water contained in 1 is consequently pushed to where it is still no printing has taken place, d. H. the ring or the plate adjusts itself automatically; the The sheet metal washer is held in place with the same amount of pressure everywhere and the tools fit to all unevenness of the work piece to be processed.
