The cold closed-die forging process of the gear is a kind of new technique of the precise forming of gear in recent years. In this paper, the cold closed-die forging process of differential satellite gear in car was analyzed through numerical simulation method. Forming mold was designed with Pro/E Wildfire2.0 which included four components : upper punch, lower punch, tooth shape upper die and lower die for Normal Cone. The three-dimensional models of satellite bevel gear mould were built and imported into numerical simulation software DEFORM-3D. Because the gear has the uniform circumferential features, in order to save time and improve the accuracy, only one tooth was simulated, and the full simulation outcome of 10 teeth was mirrored from this one. Through the numerical simulation analysis of DEFORM-3D, the instantaneous deformation and stress filed were gained. Forming defects were forecasted and the cold closed-die forging rule for satellite gear used in car was obtained which can provide effective references for no-flash cold forging process of planet bevel gear and the mold design.

Preform Shape

Methods of preform design in hot-die forging are analyzed. It is noted that despite numerous works in this fi eld, preform design is still often based on the trial-and-error method. The isothermal surfaces method for preform design is proposed and its mathematical basis is considered. The procedure for determining of the preform shape is given. The design algorithm uses the QForm metal forming simulation software to build isothermal surfaces and check in the quality of the designed die geometry by finite element modeling, as well as specially developed version of the QFormDirect CAD based on SpaceClaim™.
