Back-Stepping Design Research of Spline Die Based on Cold-Rolling Forming
The author introduces the method and steps of determining key parameters of spline cold-rolling die using back-stepping design method. To verify the feasibility of the back-stepping design method in theory, the author made forming simulation and experiment with cold-rolling tooth-entwisted spline designed, analyzing the relationship between die design parameters and spline forming precision and giving correction way. Finally, the related factors influencing the forming precision of spline are introduced and the practical significance in machine-building industry of the back-stepping design method is emphasized.
