ABSTRACT:
A die set for deforming a ferrule or similar article comprises a first die member and a cooperable second die member movable relative to the first die member along a central axis. The first die member includes first and second die elements that are disposed on opposite sides of the central axis and that are movable laterally toward and away from each other. The movable first and second elements define an expandable and contractable die nest for receiving a ferrule therein. A spring is provided for normally urging the die elements toward each other. The transverse spacing between the first and second die elements is chosen to provide an interference fit with the ferrule such that upon insertion into the die nest the ferrule is resiliently retained therein. The second die member has an anvil portion for entering into the die nest and deforming the ferrule resiliently held therein. Release of the ferrule after deformation is effected by sliding the ferrule out from the die nest.
