Based on Simufact software

the three-dimensional elastic-plastic FE model of cold and hot spinning of CuSn8 Palloy cylinder was established.The reliability was validated by experiments

and the variation of spinning force and the distribution of stress and strain in the large plastic deformation zone were analyzed.The results indicate that the radial spinning force is the primary driving force of the spinning forming

followed by the axial force

and the tangential force is the mininum value.The maximum value of the equivalent stress always appears in the three-wheel operating area

while the equivalent plastic strain always presents a gradient distribution that both ends are increased towards the middle in the axial direction and its maximum value is located at the formed zone.With the fixed other parameters

the values of spinning force and equivalent stress in hot spinning forming are less than those in cold spinning

while the equivalent plastic strain is the reverse.
