Abstract：

In order to solve the problem of processing difficulties in conical slender multi-diameter shaft turning, the three-roll cross wedge rolling process of conical slender multi-diameter shaft used as removable wall bolt was analyzed. Through the theoretical calculation of axial rolling force and finite element analysis, the each primary wedge position, the suitable broadening angle β,the wedge number and the blank size in non-symmetry axis rolling by three-roll cross wedge rolling mill were obtained. The distribution of stress and strain fields for various stages in the forming process of non-symmetry axis rolling under the condition of three-roll cross wedge rolling and the velocity and displacement fields of material flow inside the rolling parts were analyzed, as well as the stress and strain continuous variation law with time for the feature points in the whole rolling process.
