ABSTRACT:
A tool pack includes a cradle (30) that defines a space (36) into which ironing die assemblies (80, 100, 106) and a plurality of lubricating rings (78, 102, 104) each associated with an ironing ring are mounted. A lubricant manifold (152) is configured so that the lubricating rings can be manipulated into position to provide communication between the rings and the manifold. The cradle has a pair of spaced locator bars (52) exposed in the space and a cover (40) is pivotally mounted on the cradle to close an access opening and is locked by a clamp mechanism (44). The cover has deflectable metal members (62) that engage the ironing assemblies and lubricating rings and apply pressure to force the assemblies into engagement with the locator bars and also provide sealing engagement between the manifold and the lubricating rings.
