ABSTRACT:
A process for seating a lockbolt with a positioned collar, swaging the collar onto the seated lockbolt and breaking off the pintail all in one operation. A single source of hydraulic power pulls a nose piece with gripper jaws to seat the lockbolt and to break off the pintail, and to move an anvil in the opposite direction to swage a collar onto the seated lockbolt. A combination air and hydraulic system sequences these steps.
