    Abstract: The mechanism is intended for increasing the twist of radial blades (46) which are integrally forged with the perimeter rim of a rotor disc. Two guide assemblies are arranged at axially opposite sides of the blades. Each comprise circumferentially spaced channels (72,76) for slidable blade forming tools (80,82). One tool (80) of each pair has its end (84) contoured to engage the suction side of a blade, whilst the other tool end contour (90) engages its pressure side as the two tools are moved together by a press assembly. The rotor is located between the assemblies by a clamp mechanism. The rotor and twist mechanism are pre-heated.

    Abstract: Forging Method and Apparatus The present invention provides methods and apparatus 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 and a movable die comprising at least two separately movable elements which are mounted on a common axis with the stationary die. A plurality of arcuate die segments are adjacently placed in cylindrical array about the stationary and movable dies. The arcuate die segments form cavities of the inverse geometry of the appendages to be formed and in at least one embodiment are interlocked to prevent tilting of the segments in the die package. The movable die elements are sequenceable to form a billet of material into a workpiece having an intermediate configuration, and subsequently into a workpiece of final configuration. In at least one embodiment, pressure pads are disposed against one of the movable dies to prevent displacement of that die by the billet material as the intermediate configuration is formed.
