METHOD FOR MAKING ARTICLES SUCH AS WHEEL RIMS Russian patent published in 2005 - IPC

FIELD: plastic metal working, possibly manufacture of wheel rims of transport vehicles, mainly of aluminum alloys.

SUBSTANCE: method comprises steps of preparing initial blank by pressing tube of hollow ingot and cutting prepared initial blank by measured-length piece blanks; then forming intermediate blank from measured length one; after heat treatment of intermediate blank, finishing it by calibrating in die sets used for intermediate blank forming.

EFFECT: lowered metal consumption due to reduced allowance for mechanical working, elimination of warping at working, enhanced efficiency of method.
