A machine is disclosed for crimping a fitting onto a hose by means of a contractible collet assembly driven by a reciprocable ram. The ram includes a pusher assembly adjacent the working end thereof for transmitting ram force to the collet assembly. The pusher assembly includes first and second pusher members, and the pusher members are mounted for axial movement with the ram and for lateral swinging movement relative to the ram. In this manner, the pusher members transmit ram force to the collet assembly and are movable to expose the collet assembly for loading and unloading the workpiece and for changing the collet assembly to eliminate the long ram stroke and cycle time associated with prior art machines. |
