Effect of Floating Die on Tooth Filling of Spur Gear Forging
According to the analysis of friction distribution on radial direction in the precision forging spur gear, the reason that the tooth corner was difficult to fill is revealed. Changing the motion mode of the floating die will change the friction condition between billet and floating die, as well as the filling situation of tooth corner. Finally, the scheme was further validated by DEFORM-3D, and the results show that the validity of floating die to tooth corner filling.
