Abstract: A ram guidance system for a stamping press is provided including an outer bush mounted to a portion of the stamping press. The outer bush has a central passageway sized and arranged so that a reciprocating ram extends through the passageway. An inner bush is coaxially mounted to the outer bush and a portion of the rod, with an anti-friction bearing assembly positioned between the outer bush and the inner bush so as to guide their relative movement. In another embodiment of the invention, a metal stamping system for operating a die set is provided that includes an outer bush mounted to a portion of the stamping press. The outer bush includes a passageway sized and arranged so that a ram extends through the passageway so as to be enclosed by the outer bush. An inner bush is coaxially mounted to (i) the outer bush and (ii) a portion of the ram, with an anti-friction bearing assembly positioned between the outer bush and the inner bush so as to guide their relative movement.

Abstract: A punch and die set is provided for use in a stamping press having a punch assembly and a die assembly reciprocated by a driving mechanism. The punch and die assemblies are aligned to a common center and are structured to slidably engage one another for positive guidance of the punch and die tools without the need for other guidance by shafts, bars or the like. One of the punch assembly and die assembly can be non-fixedly carried by the drive mechanism, allowing the guidance of the engaged punch and die assemblies to define the relative positions of the tools. This arrangement eliminates any stack-up of tolerances between the assemblies and substantially reduces misalignment during stamping, including any misalignment that may be introduced by the press driving mechanism.
