Hot forming a cast forging ingot

A forging device for hot forming of a cast forging ingot, comprising:

• radially guided forging dies, each having two die parts which can be radially displaced relative to one another, an inner die part of the two die parts carrying a forging tool and being drive-connected to an other outer die part of the two die parts by a hydraulic cylinder;
• an eccentric drive which can drive the outer die part;
• an eccentric shaft coupled to the eccentric drive via a coupling to an electric motor;
• and
• a pump driven by the electric motor, for acting on the hydraulic cylinder between the inner and outer die parts wherein the electric motor is a torque motor which is coaxial with the eccentric shaft a rotor of the torque motor being rotatably mounted on the eccentric shaft or an eccentric shaft extension in connection with a driver flange of the eccentric shaft, and wherein the coupling is arranged between the rotor and the driver flange.
