Method of forging a part with the steps of radially closing opposed dies, applying force and then reinforcing the opposed forging dies

摘要

A method of forging a part of a predetermined shape from a workpiece 120 comprises the following steps of radially closing opposed forging dies 112 such that forging dies 112 move radially inward, in a predetermined direction to contact workpiece 120. Opposed forging dies 112 define a cavity therebetween of the predetermined shape of the resulting part. Apply axial and radial forces to the workpiece with the radially closing forging dies 112. The applying step includes the step of generating compressive and shear stresses within the workpiece such that the workpiece deforms outwardly to the predetermined shape defined by the opposed forging dies 112. During the application of compressive and shear forces, the opposing forging dies 112 are structurally reinforced with a die housing 130 which receives and circumferentially encompasses the opposed forging dies during the forging process.
