摘要： 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.
