ABSTRACT:
A unitary coining die assembly is provided which is mountable on the frame of an underdriven coining press independent of the press slide. The die assembly is positioned on the frame above the slide and is comprised of a mounting plate attached to the frame and a pair of support plates suspended therebeneath. An upper coining die is carried by the mounting plate, and a vertically displaceable lower coining die is carried by the lower support plate. A ring providing a die cavity cooperable with the coining dies is carried by the upper support plate. The support arrangement provides for the lower coining die to be pivotal laterally about an axis spaced from the die axis to facilitate access to the component parts. Further, the portion of the upper support plate is pivotal about the same axis to provide access to the die cavity ring and upper coining die. The press slide engages a die pad associated with the lower coining die and displaces the coining die upwardly into cooperable relationship with the upper coining die to shape a coin blank positioned therebetween.
