With the advantages of light weight,high precision and economy and good dynamic characteristics,the pulleys manufactured by spinning instead of being manufactured by forging or casting are widely used in many fields. The forming characteristics during six-wedge poly-pulley spinning were analyzed. The spinning forming was divided into two processes:thickening and tooth forming. The FEA simulations of the thickening process during poly-pulley spinning,including performing,drumming and thickening,were carried out by MSC.Marc software due to the importance of this process in the whole spinning forming. It indicates that the maximum radial tensile strain exists at necking area of performing workpiece during performing,and forming defects also appear on this area easily. Bulging is the main deformation during drumming. Tensile strain is mainly in the radial direction and compressive strains are mainly in the axial and tangential directions during thickening,according to the forming effect of radial compression and thickening. On the basis of FEM simulation,the experiment was carried out to prove the results of FEM. The experimental results agree well with the results of simulation,which verifies the validity of simulation.
