Abstract (en)

[origin: WO2022248008A1] The invention relates to a drive device (10) for a machine tool (100), for example, a punching machine tool, the machine tool (100) thereof, and a method for operating the machine tool (100). The drive device (10) comprises a wedge unit (20) adapted for translating movement provided by a drive unit (15) of the machine tool (100) in a first direction (X) to a movement of a ram connection portion (60)of the machine tool (100) in a second direction (Z), wherein the second direction (Z) differs from the first direction (X), wherein the wedge unit (20) defines a guide angle (21) determining a relation between a movement distance in the first direction (X) and a movement distance in the second direction (Z). Furthermore, the guide angle (21) is arranged to be adjustable.
