Finite Element Analysis on Flanging Forming of Car Spoke Parts

To improve the production quality of mini-car spoke components, the forming process of mini-car spoke components is numerically simulated by DYNAFORM, and the geometry models of punch, die, blank holder and sheet metal are established, the effect of round-hole flange coefficient, material parameters and forming craft on flanging forming is evaluated by simulation computation method, and the suggestions for improvement are discussed. The results indicates that the increase in material yield strength has a great influence on flanging cracking; and through improving flanging process, the cracking defects of round-hole flanging in the spoke components can be controlled, the cracking rate reduces to 0.1 ‰, and the better product quality can be obtained.
