基于Anycasting分析的油泵壳体低压铸造工艺优化

Design and Optimization of Low Pressure Casting Process for Shell Based on Anycasting

以有限差分法作为铸造工艺模拟研究的理论平台,运用Anycasting有限差分模拟仿真软件对油泵壳体铸件低压反重力铸造过程中可能出现的裹气、缩孔、氧化夹杂等缺陷进行模拟,较准确地预测各种缺陷的产生原因及相应缺陷位置。结合此壳体铸件的结构特点及生产实际优化铸造工艺,通过改进铸造工艺和相关参数设置获得满足质量要求的铸件,降低铸件废品率,最终获得了合格铸件。

Taking finite difference method as a theoretical platform of casting process simulation, the defects of casting gas, shrinkage cavity and oxide inclusions in oil pump housing castings were simulated in low pressure anti-gravity casting process using Anycasting software, so as to accurately predict the various causes and position of defects, to obtain the qualified casting by improving the casting process and related parameters.
