CA 2471673
The invention concerns a device for punching work pieces in an internal high- pressure forming tool, whereby the device comprises a punching die (4) that is guided displaceably in a bore (3) of the forming tool. The device also contains a drive with which the punching die (4) is moved back and forth between the in-use position and the non-use position. In order to facilitate in a simple and space-saving manner the punching of work pieces in the internal high-pressure forming tool, it is suggested that the drive contains a pressure fluid and a pressure transfer device (15) that can be elastically expanded via the pressure fluid between a base (22) firmly attached to the tool and a punch head (11) of the punching die (4), whereby the pressure transfer device (15) abuts a partition (16) at least indirectly at the punch head (11).
