Abstract：

For the shape, size and material performance of automobile transmission pin, the single step open mould forging was chosen, and the initial process scheme was simulated by CAE finite element analysis software Deform-3D. Then, thermal and mechanical conditions in the material forming were analyzed, but the feasibility of initial process was denied. From three aspects of billet size, billet temperature and mould structure, three sets of improved forming process were formulated, and a better one was obtained by simulation with billet size of Φ17 mm×47.5 mm, billet temperature of 700 ℃,fash slot of Φ60 mm×0.2 mm on female mould, and protuberance of Φ12 mm×0.5 mm on the front-end of male mould. Furthermore, the improved mould and optimized process were verified by test, and the resibility of the process was proved.
