Abstract
A cold header or a screw machine preforms a rod end blank from rod stock. A female blank has a drilled and tapped rod portion and an undersized spherical head portion. A male blank has an unthreaded straight shank and an undersized spherical head portion. The rod portion is necked adjacent the head portion. The blank is placed on an indexing table which advances the blank through a series of processing stations. The head portion is heated for three seconds with an induction coil, rested for one second, and heated again for three seconds with an induction coil. The head portion is then flattened, shaped and enlarged in a closed die press. The head portion is quenched to room temperature. The head portion is punched in a die punch to remove the slug and flash.
