Abstract
In order to drive a punching machine electrically, with the aid of a double-armed rocker (70) a translational motion for the compression beam (10) is generated on the one hand, and a rotary motion for an opposing drive on the other hand. On the one side, the double-armed rocker (70) is driven by a rotating clutch shaft (50) by way of a crank gear (60-66) and, on the other side, a chain link (73) serves to control the compression beam. The opposing drive is operated by means of a one-arm rocker (75) and, also, by means of a chain link (76). To ensure the execution of an exact cycle, an engaging and disengaging claw clutch (31, 36) is present. The cycle is maintained by a cam disk arrangement (51) on the one hand, and a coupling groove (37) on a coupling box (32) with a coupling bolt (38), on the other hand. The above provides the electric drive for a rectilinear punching machine for punching sheets of paper for mechanical binding systems.
