FIELD: plastic metal working, possibly manufacture of forged blanks with rod.
SUBSTANCE: method comprises steps of heating cut off initial blank; forming semi-finished product from it and realizing final open forging and trimming fins. Semi-finished product is formed stage-by-stage beginning from rolling part of initial blank then subjected to forging. Rod portion of semi-finished product is formed by rolling; its volume consists 0.8 - 1.2 of volume of rod portion of ready forging. During forging process rod portion of semi-finished product is finally formed. Bulged flange is formed, mainly of remaining non-deformed part of blank.
EFFECT: production of forging at lowered efforts and reduced metal consumption.
