摘要
为了解决人工设计锥齿轮冷挤压模具过度依赖经验的问题,将数值模拟应用到锥齿轮模具设计中。设计了一套用于冷挤压加工锥齿轮的三层组合凹模,制定了相应的工艺措施,利用Deform-3D软件对锥齿轮的冷挤压加工过程进行了数值模拟,分析了加工过程中的载荷曲线、速度场、应力场和温度场,获得了有关锥齿轮变形规律的基本情况。研究结果表明,通过改善润滑条件、优化模具几何参数可以提高冷挤压加工锥齿轮的成形质量,并对锥齿轮冷挤压加工工艺流程定制、模具设计具有一定的指导意义。
In order to study the cold extrusion forming of the bevel gear, a three-layers assembled cavity die and its technological measures were designed. Numerical simulation of the cold extrusion forming process was applied ,its load curve, velocity field,stress field and temperature field were analyzed. After the analysis of numerical simulation, the basic knowledge of the bevel gear deformation was obtained. In order to solve the remaining problems of the current cold extrusion forming,subsequent targets for optimization were introduced. The experiment results show some significance in guiding how to design a die and plan its technological measures.
