Abstract：

In order to study the influence of the change of process parameters on the torsion deformation of retainer ring during its forming process, the three-dimensional model of retainer ring based on ABAQUS software was established by the dynamic display integral algorithm of finite element. Then, the influences of process parameters on the torsion deformation of retainer ring were obtained by the orthogonal test. When the roll diameter, the roll speed and the hole deflection angle increase, the torsion angle of rolled piece first decreases and then increases, first increases and then decreases, and decreases respectively, and the primary and secondary sequence influencing the torsion deformation is hole deflection angle>roll speed>roll diameter. Furthermore, a mathematical regression expression for the roll diameter, the roll speed, and the hole deflection angle was constructed. Through the regression model analysis, when the torsion angle y^ was the smallest, the influences of process parameters on the torsion deformation were ideal under the condition of the roll speed was 169 r·min-1, the roll diameter was Φ360 mm, and the hole deflection angle was 13.78°.
