Abstract
A magnet actuator assembly for reciprocating a ram shaft in a crimping press. The actuator assembly comprises stationary upper and lower electromagnet members and a movable central electromagnet member coupled to the ram shaft. The mating surfaces of the electromagnet members are formed of combinations of frusto-conical and planar regions so that an adequate force at a large separation between the upper and central electromagnet members is generated to raise the central electromagnet member and a relatively large force at a small separation between the central and lower electromagnet members is generated to effect the crimping function.
