Effect of Spinning Process Parameters on the Forming Quality of Inner and Outer Teeth Shaped Parts

Abstract Deform-3d software was used to conduct numerical simulation on the spinning forming process of inner and outer teeth to study the strain distribution and material flow law during the spinning forming process. The influence of mandrel rotation speed and roller feed speed on the forming quality of inner and outer teeth profile was studied. The results show that the best forming quality of the spinning parts can be obtained under the combination of the process parameters of the mandrel rotation speed of 150r/min and the roller feed speed of 110mm/min. Compared with the experimental results, the maximum relative errors of inner and outer teeth wall thickness were 2.03% and 1.78%, which verified the reliability of the finite element model. The results can provide guidance for the finite element simulation and production of inner and outer teeth spinning forming process.
