研究了锻模中心凸台超过分模面时的变形区形状,提出了各类回转体锻件剧烈变形区和等效变形区的确定方法,并利用slab法推导出了计算该类锻件(包括锻模中心凸台超过和不超过分模面的锻件)开式模锻变形力的通用公式。
The shape of the deformation zone when the center boss of the die is over the parting plane is studied. The method of determining the deformation zone and the equivalent deformation zone of the swivel body is proposed. The slab method is used to calculate the deformation of the forging, Die center boss exceeds and does not exceed the parting surface of the forging) open forging deformation of the general formula.
