摘要
论述了轴对称圆筒件在锥形凹模中缩口时口部自由弯曲区的变形趋向,对3种变形模式进行了比较,并通过实例计算,证实了按自由弯曲变形模式计算口部应力与变形是合理性。
The non-forcing deformation trend of the axial symmetry conical necking workpiece oral area was discussed.three kinds of deformation mode were compared.through the computation of the real example,it was proved that,the stress and distortion of oral area were rationality by the free deformation mode computation.
