<p>An apparatus for reforming an end shell (100) includes a stationary tooling assembly (12) having a reform punch (22) for engaging an interior surface of the central wall portion (106) of the end shell. A reciprocating tooling assembly (14) includes spring-loaded pressure pad (38) complimentary to the reform punch for engaging the exterior surface of the central wall portion. A reform ring (58), mounted circumferentially about the pressure pad, includes an annular nose (64) for fully engaging and supporting the exterior surface of the frustoconical wall portion of the end shell. At the bottom of the reforming stroke, the central wall portion is simultaneously supported by the reform punch and the pressure pad.</p> |
