Abstract
FIELD: metal pressure forming. SUBSTANCE: method comprises steps of upsetting an initial blank up to a diameter of its barrel, equal to a diameter of a flanged thickened portion of a semifinished product; forming a hollow semifinished product with the flanged thickened portion and with a boss, having a height being no less, than a height of the forging; determining geometrical dimensions of the semifinished product according to proposed relations; providing a length of the boss of the semifinished product no more, than a length of the boss of the forging and providing a height of the flanged thickened portion of the semifinished product no less, than a height of the flange of the forging; subjecting the semifinished product, had been received with normalized geometrical dimensions, to final deforming in order to receive a high-quality forging with provision of metal economy. EFFECT: enhanced quality of forgings, increased factor of metal using, increased strength of tool. 2 cl, 3 dwg
