FIELD: plastic working of metals, possibly in forging press shops in machine engineering enterprises for making parts by sheet forming with use of ingots of own production.
SUBSTANCE: method comprises steps of plastically deforming ingot by forging in four-striker device in forging press at forging reduction ratio 1:2 -1:5 till producing forged piece with diameter d =(0.2 - 0.8)d1 where d, d1 -diameters of forged piece and blank for sheet forming at allowance for working respectively. The forged piece is cut normally to its lengthwise axis by blanks multiple to several blanks for sheet forming. Prepared blanks are heated till temperature of plastic deformation, upset till diameter d1, annealed and turned according to diameter of round blank for sheet forming, Then blanks are cut normally to their lengthwise axis by measured blanks for sheet forming.
EFFECT: improved factor of metal using, simplified process.
