FIELD: mechanics.
SUBSTANCE: invention refers to metal deformation process, and namely to manufacture of workpieces, preferably from titanium alloys, on hydraulic tube-profile presses. Workpieces are used for manufacturing wide-chord fan blades. Workpiece is pressed with compression ram travel by pressing the metal out to the cavity between external die connected to container and internal die connected to central mandrel. At that, there formed is axisymmetric workpiece with root and feather parts. Root is formed with variable height. Then the obtained workpiece is cut into sectors. Final shaping of blade workpiece is performed by die forming.
EFFECT: there is provided rational geometric shape with specified design and metal texture on general purpose equipment.
