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. ^ 1 dwg, 1 ex |
