摘要
对FDM3D打印技术在涡轮叶片熔模铸造中的应用进行了研究。设计了侧注式、顶注式和底注式浇注系统,利用AnyCasting软件分析选出了最佳铸造方案。采用增材制造技术和熔模铸造工艺制备出了合格铸件。结果表明,AnyCasting软件可以准确预测熔模铸造的缺陷;熔模铸造工艺可以很好地结合3D打印技术,并且能获得优良铸件。研究解决了由于涡轮叶片模具制造工艺繁琐所带来的铸造缺陷问题。
The application of FDM3D printing technology in investment casting of a turbine blade was studied. The gating systems of side injection, top injection and bottom injection were designed. The best casting scheme was selected using the AnyCasting software analysis. Qualified castings were prepared using additive manufacturing technology and investment casting technology. The results show that AnyCasting software can accurately predict the defects of investment casting;investment casting process can well combine 3D printing technology, and can obtain excellent castings. The casting defects caused by the complicated manufacturing process of the turbine blade mold are solved.
