ABSTRACT:
Polymeric anti-extrusion rings are provided for internal cooling of a drawbolt swaging apparatus. One such ring is located on either side of an elastomeric expansion sheath on a drawbolt. There rings are formed of polymeric material which has low creep, high tensile strength and is substantially unaffected at swaging temperatures. The rings are sized to fit snugly on the drawbolt shank and to provide minimum practical clearance with the interior dimensions of the tube to be swaged. The outer perimeter of the rings adjacent to the drawbolt head and bushing are chamfered.
