At first step, the processor before the deformable body contact the end face of cone die cavity regarded as an extrusion process. The minification of core boss's cross-section regarded as compressibility of direct extrusion, which acted as definition factor when construct the Direct Extrusion Model element. Another step, the model element of flat punch extrusion on wedge piece process was constructed when propose the process of deformable body overflow die corner. In this way the spherical end face of blank looked as cone end face one, t he approximate treatment is one of originality innovation in this paper. At last, the two elements have been connected and constructed the model element of cone boss part's deformation in the open die forging.

Medicine is used to unclose and seize mysterious physiology, pathology and pathogeny of human body, and solve problems pointedly and flexibly, but it is difficult to find a versatile medicine, operation or treatment means. So, some people cannot get away from illness despite medical treatment, some even die. Sometime, medicines are suitable for adult A, but not for adult B who has the same sickness, or do harm to infant A even lead to death; some patients get better by taking virose medicines, but others disable or die; suffering from the same sickness, some people pull through and live for another tens of years, some people die in the operating table; sickness recrudesces in some people whose families break up after several operations, etc.

医学能把人体深层奥秘的生理、病理、病因揭开并掌握，还可以针对性或应变性解决，但难以制造出广谱特效的药物和手术及用各种治疗手段来解决，所以有的病经久治疗难愈，有的病被治死，有的药可以治愈同一种病的甲成人，而不能治愈同一种病的乙成人，或对甲小儿有害甚者易致残亡；有病人服有毒性的药可以治愈病，但有的人服后致残或死；同一种病，有人手术后恢复健康活至几十年，有人死于手术台；有的手术后病情复发，然经几次手术后家破人亡，等等。
