Planetary straightening machine

DETAILED DESCRIPTION We claim: 1.
A planetary production workpiece processing machine comprising; a stationary frame, a central rigid annular element rotatably mounted on a fixed axis relative to said frame having circumferentially extending workpiece engaging tooling thereon, cooperating non-rotatably fixed non-yieldably rigid reactive workpiece engaging displacement tooling mounted on said frame in non-concentric relation adjacent to the path of said circumferential tooling extending between workpiece entering and exiting positions, said respective rotating and reactive tooling being formed with varying relative spacing accommodating and producing a planetary rolling drive and reaction engagement of the workpiece with varying relative radial displacement to perform a processing operation by stressing said workpiece beyond its elastic limit.
2.
A machine as set forth in claim 1, including axially spaced portions of said tooling adapted to engage a linear workpiece stressing portions thereof beyond the elastic limit to achieve desired processing.
3.
A machine as set forth in claim 2, with tooling adapted to provide a varying deflection bending stress in performing a straightening operation on said workpiece.
4.
A machine as set forth in claim 3, said tooling including an initial portion providing a progressive rapid deflection of the workpiece beyond the elastic limit of a straight workpiece, followed by a portion providing a relatively gradual relaxation of deflection as the workpiece progresses towards the exit position.
5.
A machine as set forth in claim 4, wherein the relaxation in deflection per revolution of the workpiece is no greater than the allowable tolerance for straightness.
6.
A machine as set forth in claim 1, wherein the tooling includes means for producing a reduction forming operation on the workpiece.
7.
A machine as set forth in claim 1, including tooling means for accommodating tooling engagement of different diameters of multi-diameter parts having a common axis, said means including separate power driven and free floating rotatable annular elements adapted to engage said different diameters
