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.

Dependent claims

A tool pack for a drawing and ironing machine comprising a cradle having an opening with closure means for said opening, said cradle defining an open space therein open at opposite ends for receiving a plurality of ironing dies with a plurality of lubricating rings interposed between respective adjacent pairs of ironing dies, a plurality of circumferentially-spaced locator means exposed in said space for engagement with said ironing dies, a manifold fixed in said cradle and having a mounting surface exposed to said open space, said manifold having a single inlet port and a plurality of outlet ports equal in number to said lubricating rings and extending through said mounting surface, each of said lubricating rings having a fitting having an exposed surface with an inlet port extending through said exposed surface so that said lubricating ring can be rotated on said locator means to produce extended surface contact between said exposed surface and said mounting surface and align said inlet port of said lubricator ring with an outlet port of said manifold, at least one of said locator means being deflectable to apply pressure to said ironing dies and lubricating rings and maintain accurate alignment of said ironing dies and lubricating rings with respect to a punch movable therethrough while producing sealing engagement between said mounting surface and said exposed surfaces.

In a drawing and ironing machine having a punch movable along a path through a plurality of ironing dies, a tool pack comprising a cradle open at opposite ends and having an opening between opposite ends with closure means for said opening pivoted along one edge of said opening and a plurality of circumferentially-spaced locator means extending between said opposite ends, said ironing dies engaging said locator means and having a lubricating ring located between each adjacent pair of ironing dies, a lubricant supply manifold fixed to said cradle and having a flat mounting surface with a plurality of outlet ports leading from a single inlet port, each lubricating ring having a fitting with an inlet port extending from a flat exposed surface so that said exposed surface can be rotated into engagement with said mounting surface and place said inlet port in communication with an outlet port in said manifold, and pressure applying means carried by said closure means for gripping said ironing dies and said lubricating rings between said locator means and said pressure applying means to accurately align said ironing dies with respect to each other and produce sealing engagement between said exposed surfaces of said lubricating rings and said mounting surface of said manifold.

A tool pack comprising a cradle that is open at opposite ends and has an opening between opposite ends with a door pivoted on said cradle to close said opening for gaining access to a space defined between said opposite ends, locator means in said space opposite said opening, said locator means comprising at least two circumferentially spaced locator bars extending between said opposite ends, a plurality of ironing die assemblies located in said space and engaging said locator bars, a plurality of circular lubricating rings respectively interposed between adjacent pairs of ironing dies and engaging said locator bars, each lubricating ring having a flat surface defining a tangential plane on a periphery thereof with a fitting secured to said flat surface and having a flat exposed surface inclined with respect to said flat surface and an inlet port therein, a manifold having a plurality of outlet ports extending through a mounting surface which is in extended engagement with said flat exposed surface, and pressure applying means carried by said door for forcing said ironing die assemblies and lubricating rings into engagement with said locator bars for maintaining said ironing assemblies in fixed positions within said cradle while applying a sealing force between each exposed surface of each lubricating ring and said mounting surface of said manifold when said door is in its closed position.
