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.
