Swaging apparatus

Abstract

A hand actuated swaging device for securing a metallic fitting to an end of a hose has a one-piece cast frame with an integral die support. A ball screw and ball nut assembly is supported by the frame. The screw carries a pusher which presses a fitting into a swaging die without rotation with the screw. .Iadd.A generally triangularly shaped clamp is provided which is pivotally secured at its apex to side support members and having an arcuate shaped base disposed to press the die into an opening through an end member of the frame..Iaddend.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:  .[.1. An apparatus for securing a fitting to a hose which comprises a ball screw and ball nut assembly, a swaging die having a die cavity adjacent one end of the screw with the cavity aligned with the screw, means for supporting said ball nut and said die against relative longitudinal movement and against rotation with the screw comprising a cast one-piece frame having a first end member, a second end member spaced longitudinally from the first end member and a pair of laterally spaced side support members integral at one end thereof with the said first end member and integral at the other end with the said second end member, an opening through the said first end member and an opening through the second end member for supporting the swaging die, said openings having a common axis, said ball screw passing through said opening through the first end member and said ball nut secured to said first end member, means carried by said end of the screw for pressing a fitting and hose assembly in said die cavity comprising a holder element secured to the said screw end for rotation therewith and having a cavity therein, a pusher element having one end in the cavity of the holder element and an opposite end adapted to support a fitting and hose assembly as it is moved towards the die cavity, means for securing the pusher element in the cavity of the holder element against rotation with the screw and against substantial longitudinal movement relative to the screw comprising a thrust bearing in the cavity of the holder element and about the said pusher, and means for turning the screw in the nut..]. .[.2. The apparatus of claim 1, wherein the die is segmented..]. .[.3. The apparatus of claim 1, having a leverage arm pivotally secured to the frame for supporting the apparatus..]. .[.4. The apparatus of claim 1 comprising a generally triangularly shaped clamp pivotally secured at its apex to each of said side support members and having an arcuate shaped base disposed to press the die into the opening through the said second end member of the frame..]. .Iadd. 5. An apparatus for securing a fitting to a hose which comprises a ball screw and ball nut assembly, a swaging die having a die cavity adjacent one end of the screw with the cavity aligned with the screw, means for supporting said ball nut and said die against relative longitudinal movement and against rotation with the screw comprising a cast one-piece frame having a first end member, a second end member spaced longitudinally from the first end member and a pair of laterally spaced side support members integral at one end thereof with the said first end member and integral at the other end with the said second end member, an opening through the said first end member and an opening through the second end member for supporting the swaging die, said openings having a common axis, said ball screw passing through said opening through the first end member and said ball nut secured to said first end member, means carried by said end of the screw for pressing a fitting and hose assembly in said die cavity comprising a holder element secured to the said screw end for rotation therewith and having a cavity therein, a pusher element having one end in the cavity of the holder element and an opposite end adapted to support a fitting and hose assembly as it is moved towards the die cavity, means for securing the pusher element in the cavity of the holder element against rotation with the screw and against substantial longitudinal movement relative to the screw comprising a thrust bearing in the cavity of the holder element and about the said pusher, a generally triangularly shaped clamp pivotally secured at its apex to each of said side support members and having an arcuate shaped base disposed to press the die into the opening through the said second end member of the frame, and means for turning the screw in the nut. .Iaddend.
