-10- Die Assembly for Use in Forging Operations Abstract The present invention provides a technique for improving the dimensional accuracy of forged components. Uniformity of like component details is sought and a specific object is to provide a die package for forming closely toleranced appendages integrally with a central disk structure from which the appendages extend. In one effective embodiment incorporating concepts of the present invention, the forging dies include a stationary die 26 and a moveable die 28 which are mounted on a common axis and a plurality of arcuate die segments 30 which are adjacently placed in cylindrical array about the stationary and moveable dies. The arcuate die seg- ments form cavities of the inverse geometry of the appen- dages to be formed and are interlocked to prevent tilting of the segments in the die package. A collar 40 extends from the stationary die to interlocking engagement with a channel 46 in the inwardly facing surface of each arcuate die segment.
