  • Method of manufacturing articles by deformation of cylindrical blanks
    Patent number: 4489581
    Abstract: Disclosed is a method of manufacturing articles by deformation of cylindrical blanks, comprising heating the blanks (1), their transverse wedge forming followed by deformation of the end crops (3) by shearing blades, separating the end crops (3) from the formed blanks (2), and flashless forging of the formed blanks (2), separation of the end crops (3) from the formed blanks (2) being performed by reducing the speed of rotation of the end crops (3) after deformation down to a value ranging from .omega./2.5 to zero, where .omega. is the speed of rotation of the blank (2) during forming.
