Hose fitting

Abstract

A machine, tooling and method for cold forming complex metal parts such as a banjo style hose fitting starting with a near net shape volume of wire and continuing with multiple forging blows and an intermediate rotation of the blank to produce a hose coupling shell end, a transition neck, a large counterbored annular coupling body and a perpendicular alignment tang.

         5 . A banjo style hose fitting comprising a cold formed metal part, the part including an extruded open end hollow, cylindrical shell at one end, a circular coupling body having opposed generally parallel faces and a counterbore open at each of said faces, and a round neck portion between the shell and coupling body, the shell neck and coupling body defining a common longitudinal axis of the fitting. 
     
     
         6 . A banjo style hose fitting as set forth in  claim 5 , wherein the counterbore includes an end wall formed by shearing the wall of the counterbore. 
     
     
         7 . A banjo style hose fitting as set forth in  claim 5 , including a locating tang projecting from the coupling body at a location opposite the neck. 
     
     
         8 . A banjo style hose fitting as set forth in  claim 7 , wherein the tang is an extruded element having a diameter smaller than the diameter of the neck. 
     
     
         9 . A banjo style hose fitting as set forth in  claim 8 , wherein the distal end of the tang is bent into an orientation parallel to an axis of the counterbore and perpendicular to the longitudinal axis of the fitting.
