Effect of Cold Forging Technology for Spur Gears Based on Radial Divided-flow
The great forming load exists in the cold forging of spur gears,the application of this process in industry was restricted.Taking friction coefficient,fillet radius of die tooth root,diameter of divided hole and forming speed as process parameters,based on the theory of radial divided-flow and the process of floating-die,the cold forging of spur gears was numerically simulated,the rule that the process parameters affected the forming load was got.The simulation results show that the effects of friction coefficient and diameter of divided hole on the load are greater,while the effects of fillet radius of die tooth root and forming speed aren't evident.
