Abstract

Beschrieben wird eine hydraulische Antriebseinrichtung für ein Werkzeug zum Fügen mindestens zweier Werkstücke aus duktilem Material wie z.B. zum Stanznieten oder Durchsetzfügen. Die Antriebseinrichtung besteht aus einem Stempelantrieb zum Betätigen eines Stempels für den Fügevorgang und einem Niederhalterantrieb zum Betätigen eines die Werkstücke während des Fügevorgangs einspannenden Niederhalters. Beide Antriebe sind als Kolben-Zylinder-Einheit ausgebildet. Die Kolben-Zylinder-Einheit des Niederhalterantriebs wird von der Kolbenstange des Stempelantriebs getragen. Ferner ist die Druckkammer des Niederhalterantriebs mit der einen Arbeitskammer des Stempelantriebs so verbunden, daß zum Erzeugen der Niederhaltekraft Druck in der Arbeitskammer des Stempelantriebs auf die Druckkammer des Niederhalterantriebes übertragen wird. Somit sind nur zwei Anschlüsse zur Druckversorgung beider Antriebe erforderlich.

Figure 00000001
A hydraulic drive device for a tool for joining at least two workpieces made of ductile material, such as for example punch riveting or clinching, is described. The drive device consists of a punch drive for actuating a punch for the joining process and a hold-down drive for actuating a holding-down device which clamps the workpieces during the joining process. Both drives are designed as a piston-cylinder unit. The piston-cylinder unit of the hold-down drive is carried by the piston rod of the stamp drive. Furthermore, the pressure chamber of the hold-down drive is connected to the one working chamber of the punch drive in such a way that, in order to generate the hold-down force, pressure in the working chamber of the punch drive is transmitted to the pressure chamber of the hold-down drive. This means that only two connections are required to supply pressure to both drives.
