Abstract: A cold forging apparatus for forming complex shapes at a single station includes a plurality of multiple function punch assemblies disposed on intersecting axes. Each of the multiple function punch assemblies includes an inner or a center punch and an outer or ring-shaped punch surrounding and in sliding contact with the inner punch. The apparatus also includes a die holder for positioning a mass or slug of metal between the punches. A computer system controls movement of the punches and is programmable to form parts of different shapes at a single station. Off axis punches and angularly offset punches and an additional punch or punch assembly are also disclosed.

Abstract: A cold forging apparatus for forming complex shapes at a single station includes a first multiple function punch assembly having an inner and outer punch. A third punch or a second multiple function punch assembly is provided in a confronting relationship with the first multiple function punch assembly. A conveyor conveys a metal work piece from a supply source to a loading/unloading area between the first multiple function punch assembly and the third punch or second multiple function punch assembly. The conveyor includes a pivot assembly, a moveable J-shaped robot arm having an end effector fixed to one end thereof to rotate about the pivot assembly. A servo actuator and crank arm connected to one end thereof rotate the robot arm and end effector to convey a metal work piece from a supply source to a loading/unloading position and for conveying a forged product from the loading/unloading position to a storage area.

Abstract: A cold forging apparatus for forming complex shapes at a single station includes a pair of confronting multiple function punch assemblies disposed on a common axis. Each of the multiple function punch assemblies includes an inner or a center punch and an outer or ring-shaped punch surrounding and in sliding contact with the inner punch. The apparatus also includes a die holder for positioning a mass or slug of metal between the punches. A computer system controls movement of the punches and is programmable to form parts of different shapes at a single station.
