【摘要】 介绍了一种环形油缸驱动的粉末成形模架,并通过有限元方法对模架静特性和动特性进行了分析计算。本粉末成形模架采用环形油缸驱动,减小了模架的体积,节约了制造成本,且模具更换比较简便。有限元分析计算结果表明本模架的强度和刚度符合使用要求。更多还原

【Abstract】 The P/M(powder metallurgy)mold-frame with annular-cylinder was presented,and finite element method(FEM)was used to analyze the static property and dynamic property of the mold-frame.This mold-frame is driven by annular-cylinder,the volume of mold-frame is reduced and manufacture cost is spared,and it is convenient to change die.The result of FEM displays the intensity and stiffness of this mold-frame accord the requirements.更多还原
