FIELD: metal working by ultrasonic forging; manufacture of blades at enhanced technical and service characteristics.
SUBSTANCE: edge of plate is placed between taper surfaces of strikers located opposite each other for forming wedge-shaped blade and is subjected to deformation by ultrasonic forging. Plate is moved relative to longitudinal axes of strikers in transversal direction. Strikers connected with ultrasonic oscillation source are rotated about their longitudinal axes with the aid of drive. Taper working surface of each striker has recess whose generatrix corresponds to shape of surface of wedge-shaped blade.
EFFECT: improved quality of tool cutting edge; increased productivity; enhanced wear resistance of fittings.
