Power spinning is a highly efficient processing method to make cylinders of thin wall.But it will be influenced by many kinds of processing parameters.In order to improve the processing technology and the product quality,several processing parameters,which can greatly influence the process are selected to make the analysis and comparison.The inherent laws between the spinning processing parameters selection and the product production flaw have been proved.It puts forward some feasible processing parameters selection modes.The conclusion is that the shape parameter of roller must be chosen within the scope of the theory formula and experience,the ratio of feeding must consider the influence of percent thickness reduction,pipe billet thickness,roller diameter,radius of curvature and so on.Usually they are selected between 0.5mm/r and 1.5mm/ r.Ordinary cylinders are shaped by multi-passes, the thickness reduction ratio should be increased gradually,the thickness reduction size should be decreased progressively;Cylinders with inner ribs are shaped in one pass using big thickness reduction ratio or use different mandrels to realize the preliminary shape and the final forming.The spinning force must considerate the influence of every kind of process parameters.Thus,good quality product can be processed after adjustment,which provides a certain technical support and the theory guarantee for this process.
