摘要: 针对9310钢螺旋锥齿轮的模压淬火的过程,采用有限元分析软件建立了温度场-组织场-应力应变场耦合分析模型,并进行了模压淬火工艺的数值模拟研究。结果表明,模具设计对零件的模压淬火畸变有着重要影响。通过调整模具的组合尺寸和压力角,可以显著减小齿轮畸变;上下模的偏心可以导致齿形畸变,通过调整芯模尺寸可以避免由于设备对中偏差导致的畸变。

Abstract: Thermal-phase transformation-strain/stress multi-physical coupled model was established for die quenching process of 9310 steel spiral bevel gear by finite element software, and the numerical simulation of die quenching process was carried out. The results show that the design of mold has significant effect on die quenching distortion. The distortion of gear is obviously reduced by optimization of assembly dimensions and pressure angle of the mold. The eccentricity of upper and lower mold causes the distortion of gear, while it can be avoided by adjustment of core mold dimensions.

Key words: 9310 steel, spiral bevel gear, die quenching, numerical simulation, heat treatment distortion
