Abstract
The present invention provides an apparatus for producing in a single stroke a forged metal article with a helical contoured surface. The apparatus uses an upper punch with a generally smooth surface which is telescopically received in a punch housing and a lower punch of generally smooth surface which is mounted for free rotation with respect to the axis of the die assembly. This design allows for the use of a die of the general configuration and length of the finished article which is economical and efficient to operate.
