摘要

Process for simultaneously producing separated workpieces (6, 7) by inner high pressure or hydro deformation comprises exposing cutting edges (9, 10) during deformation, and passing a blank into a gap (8) between the cutting edges during deformation. Deformation I carried out using a calibration pressure selected so that the blank lies completely in negative molds (4, 5) on the inner wall (3). A gap width (11) of the gap is dimensioned so that the workpieces can be separated at the calibration pressure. An independent claim is also included for a device for carrying out the process.
