The working principle of win-roll swing rolling was introduced,and the effective calculation method and research results of winroll swing rolling parameters were obtained by knowledge of mechanics and geometrics,rolling theory and metal plasticity forming theory.Then,the force and energy parameters of win-roll swing rolling were systematically analyzed researched in theory,and the calculation method and its corresponding solving formula of effective rolling area,rolling stress and rolling torque were obtained. Furthermore,the rolling parameter of one ring workpiece in actual production was solved by the above method and solving formula,and the above calculation method was verified by experiments. The results show that the actual result is consistent with the theoretical result,and the maximum deviation is not more than 13. 6%. Thus,the calculation of win-roll swing rolling is reasonable,and it provides a theoretical reference for the parameters selection of win-roll swing rolling.
