FIELD: technological processes.SUBSTANCE: invention relates to metal ring part rolling. Part is installed between three rolls, which provide deformation and continuous running-in between them. Maximum workpiece deformation is determined from equality:wherein D is diameter of outer surface part, W is moment of resistance to bending, [σ] - part material yield point, Ε is modulus of elasticity of material part, J is axis moment of inertia of cross section part, k- coefficient of allowable error (k= (1.4-1.7)), F is cross section area of part.EFFECT: higher processing efficiency and expanded performances as process result.2 cl, 1 dwg, 1 ex |
