Abstract：

The ring blank cold extruding process of the spherical housing part was researched by a combination of rigid-plastic finite element simulation with experiment. The problems of oral filled short, thickness difference, crack in tension, etc. in the forming process were solved by adjusting blank shape, die structure and forming process parameters. The cold extruding process was optimized, and the spherical housing part with high dimensional precision and perfect mechanical property was obtained by a way of saving energy, saving material and high efficiency. The experimental result shows that oral filled short of cup-shaped piece can be compensated by designing lug boss on the billet, the influence of the free deformation on the back extrusion can be eliminated by core rod constraining deformation of ring blank inner surface, and the blank shape and die size are optimized by applying additional compression stress to material, adjusting lubrication and anneal parameters to gain the suitable deformation condition of material flow so as to improve material plastic in the extruding process.
