Patent ID: 8776682

Claim:
A press for deformation of metal sheets or massive metal components comprising at least one press drive, each of the at least one press drive including an eccentric shaft carrying an eccentric and a connecting rod connected to the eccentric to be activated thereby, the axis of the eccentric shaft offset from the axis of the eccentric, the connecting rod having a first opening operatively surrounding the outer circumference of the eccentric, a direct electric drive including permanent magnets disposed on one of the outer circumference of the eccentric and the inner surface of the first opening of the connecting rod and windings disposed on the connecting rod or, respectively, the eccentric for generating a relative rotational movement between the eccentric and the surrounding connecting rod, the eccentric and surrounding connecting rod in operative relationship with the direct electric drive without mechanical motion transmission apparatus, for generating the relative rotational eccentric movement between the eccentric and the surrounding connecting rod for producing said deformation.
