FIELD: technological processes. ^ SUBSTANCE: in the first version of method hollow tubular billet is deformed on burnisher by cold radial forging with molding of rod body and head, with deformation degree of 2-20% during deformation of head, and 2-40% during body deformation. In the second version of method hollow tubular billet is deformed, and its external diameter corresponds to the largest diameter of finished rod head, by cold radial forging with molding of body, deformation degree makes 2-40%, after deformation internal surface of rod heads is honed. ^ EFFECT: higher strength characteristics, smaller weight and high quality of internal surface. ^ 2 cl |
