FIELD: plastic working of metals, possibly forging shops of metallurgical and machine engineering factories at making automobile wheels and similar products.
SUBSTANCE: method comprises steps of preparing initial blank by hot die forging; forming intermediate semi-finished product in the form of cup with wall passing to its bottom and with front rim in bottom zone and back rim near free end of cup; calibrating received intermediate semi-finished product according to final size between rims due to changing cup depth at applying deforming effort along axis of sleeve to back rim or to near-bottom portion of sleeve and fixing other of said two portions. Then calibrated semi-finished product is subjected to heat treatment and mechanical working.
EFFECT: possibility for producing semi-finished products of wheels with different distances between rims due to using universal fitting that needs only minimized tuning.
