Effect of Floating Die on Precision Forging of Spur Gear
According to the analysis of friction distribution on radial direction in the precision forging of spur gear,the reason that the corner was difficult to fill was revealed.Changing motion mode of the die,can change stress distribution of axial direction,as well as the fill situation of corner.Finally,the scheme was further validated by DEFORM-3D,and the results show that the effect of floating die on filling the corner is valid.
