摘　　要：本文分析了普通直径φ1.5 mm钼杆物理特性,对弯曲成型的要求,折弯过程工件因弹性塑性变形导致发生弯曲回弹的原因,弯曲回弹的表现形式,影响弯曲回弹的因素,回弹值理论计算和试验模具测试,通过材质,钼杆成型工艺,模具校正补偿等方法,控制减小回弹值。结论需根据零件批量大小,零件精度要求,模具设计条件选择相应的成型控制方法。The physical properties of molybdenum rod are discussed in this paper, as well as the requirement of the bending, reason of springback with elastic deformation and plastic deformation, form of deformation, theoretical calculation and mold test of the springback value.The springback value was reduced by changing materials, tech-nologies and mold adjusting.According to the batch size, products precision requirement and the mold design con-dition, the right control method was choosen.
