Research on Cold Taper-Rolling Law of the Spiral Blade Based on Finite Element Method

Abstract:

The taper-rolling model, the elastic-plastic constitutive equations with limited deformation conditions, and FEM model for the cold rolling process of spiral blade are established. The FEM software SUPERFORM based on elastic-plastic theory is adopted to simulate the spiral blade forming process for the first time. The influence of different parameters (feeding height H, adjusting parameter of the working pressure 1 S , translation slip S2 , elastic angle θ , workpiece material and friction coefficient) on the shape of spiral blade are simulated and analyzed systematically. And the law of the forming of spiral blade is concluded. The simulation results indicate that workpiece is very regular and there is in good agreement between simulation and practical results. The results obtained by simulation provide a foundation for optimizing production and adjusting parameters of taper-rolling.
