Abstract

The invention relates to a drive device (19) for a secondary drive of a press and in particular of a drawing press (10). The drive device (19) serves in particular as a bed cushion drive. It has an electric linear motor (27), the rotor (46) of which is rigidly connected to a transmission piston (35) of a fluidic transmission unit (28). The fluidic transmission unit has a first pressure chamber (38a), which is connected via a first fluid line (39) to a first working chamber (41) of a working cylinder (29). The fact that the piston area (F1) of the transmission piston (35) that is adjacent to the first pressure chamber (38a) is smaller than the piston area (F3) of the working piston that is adjacent to the first working chamber (41) means that an increase in the force of the linear motor (27) by a factor corresponding to the ratio of the areas is achieved. This allows the forces necessary at the working cylinder (29) to be achieved with the aid of the linear motor (27).
