ABSTRACT:
A process and apparatus for cold extruding gear teeth and projections comprises machining an annular ring gear blank with precision inside and outside diameters. The gear blank is mounted on a die ring which is arranged coaxially with respect to the blank. The die ring has internal die teeth. A mandrel having external die teeth is axially aligned with the gear blank. The mandrel or die ring is moved axially to extrude the blank through the internal and external die teeth.
