研究了摩擦压力机打击时机身和立柱的弹性变形,提出了利用机身弹性变形确定模锻变形力的方法并用该法测定了精锻伞齿轮的变形力。 The elastic deformation of the fuselage and the column during the impact of the friction press was studied. The method of using the elastic deformation of the fuselage to determine the forging deformation force was proposed and the deformation force of the precision forging bevel gear was measured by this method.
