ABSTRACT:
A lift unit is mountable upon a press or machine tool and comprises a housing having a back plate mounting a pair of upright guide rods and journal an upright feed screw. A carriage has a carriage plate guidably mounted upon the rods and threadably engaging the feed screw. A programmable DC motor upon the housing has a drive shaft coupled to the feed screw. An angularly adjustable support cradle depends from the carriage below the housing and is adapted to mount a workpiece gripper tool adapted for programmed transverse controlled reciprocal movements relative to the press. An electronic encoder upon the motor controls the direction and number of rotations of its drive shaft for effecting a programmed repetitive cycle of predetermined feed movements of the carriage.
