METHOD OF STRAIGHTENING AUTOMOTIVE WHEEL DISCS Russian patent published in 2013 - IPC B21D1/10 

FIELD: process engineering.

SUBSTANCE: invention relates to automotive parts repair and reconditioning, particularly, to straightening wheel disc surfaces and may be used in reconditioning cast and stamped wheel discs deformed in operation. Location and numerical magnitudes of end and radial play are defined to eliminate warpage in two steps. At first step, end play is eliminated by applying force along disc rotational axis and locking disc on swivel washer by standard holes intended for locking it at wheel axle hub using adjustable stops for preventing bending. At second step, radial play is eliminated by applying force in radial direction. Note here that disc is fixed in stationary jaw chuck to clamp the disc by its edges. Note here that straightening is periodically diagnosed by revolving the disc. For this, jaw chuck is unclamped to fix disc in centres without removal from test bench.

EFFECT: higher accuracy of reconditioning.
