Abstract:
1. A cone-type swaging press comprising: a single piston member axially movable along an actuation axis during a swaging process, said single piston member having at least one group of a plurality of substantially flat die shoe engaging surfaces connected together at adjacent axially extending edges to form fixed corners with each said substantially flat die shoe engaging surface facing inwardly toward said actuation axis and being angled to converge toward said actuation axis, said substantially flat die shoe engaging surfaces defining in transverse cross-section, a fixed polygonal shape; drive means for driving said single piston member axially along said actuation axis during a swaging process; and a plurality of die shoes engaged by the substantially flat die shoe engaging surfaces of the single piston member to move said die shoes radially inwardly as said single piston member is moved axially along said actuation axis, a respective said die shoe being located at each said fixed corner of said polygonal shape such that engagement portions of said die shoe at said fixed corner engage said substantially flat die shoe engaging surfaces on either side of said corner.
