Abstract

A workpiece is warm forged in a closed die set by firstly preparing a billet of predetermined vol. equal to that of the workpiece, heating the billet to warm forging temp. and forging in the die set in which an ejector also forms part of the female die. The male die forms the workpiece in a single stroke in the female die and the ejector is then fully extended to eject the formed workpiece from the die set. Used in the mfr. of connecting rod end caps for use in internal combustion engines. The use of warm forging temps. reduces the occurrence of scale or oxide growth on the workpiece and enables the latter to be produced to a high dimensional accuracy.
