FIELD: plastic metal working, possibly manufacture of forging with rod.
SUBSTANCE: method comprises steps of heating cut off initial blank, forming semi-finished product and finally forging it. Semi-finished product is formed at first by rolling part of initial blank and then subjecting it to forging. Rod portion of semi-finished product is formed by rolling; volume of said portion consists 0.8 -1.2 of volume of forging rod. Rod portion of semi-finished product is formed by finish forging process. Flange thickened portion of semi-finished product is formed, mainly from remaining non-deformed part of blank. Then blank is finally formed in closed die set.
EFFECT: lowered effort for making forging at reduced metal consumption.
