泵叶轮冲压焊接工艺

Study on Stamping and Welding for Impeller

从结构设计、冲压及焊接工艺方面提出了泵叶轮成型工艺方法,完善了现有泵叶轮冲压成型工艺。采用了带有锥度的前盖板以及S形扭曲叶片,运用激光焊接技术对叶片及盖板进行焊接,解决了后盖板冲压后的变形问题。

The paper introduces a new shaping method of impeller based on the designing,stamping and welding technology,perfects the current shaping technology of stamping and welding of impeller. This shaping technique adopts fastigiate shroud and the distortional vanes,makes use of laser technique to joint the vanes and shroud ,tackles the distortion problems of hub according to the mechanical properties of material.
