Abstract
A pusher rod extends lengthwise through the eccentric shaft. An additional disk clutch is located inside of the flywheel, which disk clutch is connected to a shaft section, which engages the pusher rod via a screw thread connection. This allows the drive of the punching press to translatorically shift the pusher rod via the further disk clutch. The pusher rod operates the movement of a locking pin, which locks the eccentric shaft to the eccentric bushing by a corresponding translatoric movement. The pusher rod operates furthermore a braceable coupling disk which transmits the driving force from the eccentric shaft to the drive apparatus of the workpiece feed drive. In order to operate these control units when adjusting the stroke of the press it is merely necessary to operate the machine drive in one or the other sense of rotation causing a corresponding closing or opening of clutches and locking members. No further drives are necessary for generating any control movements necessary for the adjusting of the stroke of the punching press. Furthermore, all control movements originate from the side of the flywheel such that a compact design is arrived at.
