Abstract:
1. A cold forging apparatus for performing multiple functions at a single station to form complex shapes, said apparatus comprising a first multiple function punch assembly including a first inner punch and a first outer punch movable along a common axis with respect to one another, a second movable punch assembly including a second inner punch and a second outer punch movable along a common axis with respect to one another, means for moving said punches individually along said common axes, and means for positioning a die between said first multiple function punch and said second multiple function punch assemblies for receiving and containing a mass of material therein to be acted upon by said punches, and programmable logic controller, multi axis controller and feedback devices including a position sensor and pressure sensor for each of said punches and means for controlling movement of said punches individually along said common axes in response to the sensed pressure and position of said punches to thereby form a complex shape.
