The spiral shafts are usually fabricated by the cutting, this paper uses the cross wedge rolling process of the spiral shaft parts. Firstly, according to the deformation stages of rolling narrow spiral step, accurate shaping surface of the mold is designed. Meanwhile, this paper finds that the starting point of the shaping curve is not in the stretching stage but advances to the knifing stage. Secondly, based on the FE software DEFORM-3D, the rigid-plastic finite element model of the cross wedge rolling of spiral shaft parts was established, and the rolling process was simulated. The forming qualities in both cases of having shaping curve and no shaping curve were compared, from which we can find that the forming quality of having shaping curve is better, it also shows that the shaping curve is correct, and the process of cross wedge rolling of spiral shaft is feasible.
