ABSTRACT:
A swaging apparatus in which a pusher member pushes a hose coupling sleeve having a hose end portion therewithin downwardly into a die cavity of a closed die defined by mating segmental die members in a retainer to radially deform said sleeve into gripping engagement with said hose characterized in that upward retraction of the pusher member automatically opens the die by effecting upward and lateral separating movement of said die members thus to release the swaged hose-coupling assembly for downward discharge from between the separated die members and through said retainer. The swaging apparatus is further characterized in that before the pusher member commences its downward swaging stroke on the next unswaged hose-coupling assembly inserted upwardly through the retainer and between the separated die members, the latter are released for movement by gravity into mating engagement within said retainer. The swaging apparatus is yet further characterized in that the opening of the die entails a prying (or a tearing away or tilting) motion of the segmental die members to facilitate stripping of the die members from the swaged hose-coupling assembly.
