Title: Simulation and experiment research on forging flow lines for aluminum alloy wheel-hub
Abstract: The simulation of forging flow lines for aluminum alloy wheel-hub was carried out on the condition of different process parameters by using software platform Deform 2D.The experiment of forging process for reduced-scale wheel-hub was performed to verify the simulation results.The results show that a proper increase of friction between the mould and billet contributes to reduction of the angle between flow lines and workpiece surface,and prevention of flow lines outcrop.In comparison with the hot die forging,due to higher temperature and lower velocity in isothermal die forging with the temperature of the billet and models 450 ℃ and the velocity 0.1 mm/s,the metal strain resistance is reduced greatly,and the flowability of metal in the mould is improved.Therefore,the reasonable flow lines and uniform fine grain are obtained and the defects such as forging cracks and underfill occurring in hot die forging can be avoided.
