METHOD FOR MAKING BLANKS OF WHEEL TYPE ARTICLES Russian patent published in 2002 - IPC

FIELD: plastic metal working, namely modified techniques for making wheel type articles by forming and rolling processes. SUBSTANCE: method comprises steps of cutting elongated round ingots by initial blanks with flat ends; heating blanks until deforming temperature; removing furnace scale out of end surface of heated blanks by milling; acting upon flat end surfaces of blanks by rotating milling cutters simultaneously at two sides along the whole end surface directly after their heating for deformation; rotating milling cutters to opposite directions at the same effort of their pressing to both sides of blanks; performing parallel working by milling cutters of end surfaces of blanks at changing inclination angle of milling cutters in range (0 - 5) degrees relative to axis (lateral surface) of blank; after descaling soaking blanks in air for (5-20) c before deformation. EFFECT: guaranteed descaling of end surface of heated blanks, elimination of turning of wheels along formed portion of disc at restoration. 5 cl, 2 dwg, 1 ex
