| Abstract: | Semi hot forging process of automobile external star-wheel is investigated by using physical simulation and numerical simulation. The semi hot deformation behavior of Cf53 steel is studied by a compression test. The best range of deformation parameters are predicted by using the flow stress model and FEM simulation. The forging process is simplified, energy consumption is reduced and the product of high strength, hardness and good toughness is acquired by control of semi-hot forging process. |
| Keywords: | precision forging semi hot forming numerical simulation |
