  • Patent number: 6857305
    Abstract: The present specification discloses a swaging press including a piston member co-operable with a plurality of die shoes to drive the die shoes inwardly upon axial movement of the piston member during a swaging operation, the piston member having a frusto-conical recessed region divided into a plurality of circumferentially disposed bearing surface zone of a defined axial length, each of the bearing surface zones having an inner axial end with a numerical radius of curvature less than or equal to the radius of curvature of a circular line forming the lateral edges of each of the bearing surface zones at the inner axial end whereby at least 50% of the outer bearing surface of each said die shoe remains in bearing engagement with the adjacent said bearing surface zone over the axial movement of the piston member during a swaging operation.

  • Publication number: 20030230128
    Abstract: The present specification discloses a swaging press including a piston member (30) cooperable with a plurality of die shoes (40) to drive the die shoes inwardly upon axial movement of the piston member (30) during a swaging operation, the piston member (30) having a frusto-conical recessed region (31) divided into a plurality of circumferentially disposed bearing surface zone (33) of a defined axial length, each of the bearing surface zones (33) having an inner axial end (35) with a numerical radius of curvature less than or equal to the radius of curvature of a circular line (36) forming the lateral edges of each of the bearing surface zones (33) at the inner axial end (35) whereby at least 50% of the outer bearing surface (41) of each said die shoe (40) remains in bearing engagement with the adjacent said bearing surface zone (33) over the axial movement of the piston member (30) during a swaging operation.
