摘    要：以钼制品粉末热锻实验为基础,研究和讨论了粉末热锻模具的材料选择、结构设计和型腔径向尺寸的精确计算.着重讨论以往铁制品粉末热锻模具设计的理论和经验公式对难熔金属钼粉末热锻模具设计的适应性.变换C.L.Doweny理论公式并应用于模冲芯杆尺寸的计算,其结果令人满意.分析了经验公式中经验参数β值的物理意义及其应用.

Abstract: In this paper, the problems of selecting materials, structural design and precise calculation of radial dimensions of the mold cavity in the powder hot forging dies have been investigated and discussed on the basis of powder hot forging experiments of the modybdenum products. The emphasis is put on the discussion of the applicability of the theoretical and empirical formulas used in the die design for the ferrous powder h ot forging to the refractory metal molybdenum powder hot forging die design. Transpasing C. L. Doweny’s theoretical formula and applying it to the calculation of the dimensions of core rod of the punch, we obtained very satisfactory results. The physical meaning and application of the empirical parameter β in the empirical formula are analysed.
