采用消失模铸造生产行星轮架具有诸多的优势,但其球铁材质及铸件结构原因容易产生缩孔、缩松缺陷。首先使用CAE软件对原铸造工艺进行模拟,发现铸件在关键部位产生了缩孔、缩松;其次进行了铸件试生产,解剖铸件结果验证了模拟的准确性;最后基于均衡凝固理论结合CAE,优化了铸造工艺方案,得到了合格的铸件。 The use of EPC production of planetary wheel carrier has many advantages, but the ductile iron material and casting structure are prone to shrinkage, shrinkage defects. First of all, the original casting process was simulated by CAE software. It was found that the castings produced shrinkage cavities and shrinkage in the key parts. Secondly, the casting trial production was conducted. The results of the anatomic castings verified the simulation accuracy. Finally, based on the theory of equilibrium solidification combined with CAE, Casting process scheme, has been qualified castings.
