- 摘要:
- 根据TDV100缸体的结构特性,分析铸造难点,设计了缸体的铸造工艺。采用三乙胺冷芯盒法进行制芯和呋喃树脂砂造型;浇注系统设计为中间注入式,其截面呈半封闭式的浇注系统,并在油底壳安装面和轴瓦面上分别设计排气棒和排气片;熔炼方面采用了稀土孕育剂和硅钡孕育剂进行复合孕育处理,有效的改善了铸件的力学性能;样件严格执行工艺方案并对其进行质量检测,结果表明,缸体的力学性能和石墨形态均符合要求,铸件表面及内部未发现缺陷,缸体质量良好。
According to the structural characteristics of TDV100 cylinder block,the casting difficulties are analyzed and the casting process is designed.Triethylamine cold box method was used for core making and fiiran resin sand molding;The gating system is designed as the middle injection type,and its section is semi closed.The exhaust rod and exhaust piece are respectively designed on the oil pan mounting surface and the bearing bush surface;In the aspect of smelting,RE inoculant and Si-Ba inoculant were used for compound inoculation,which effectively improved the mechanical properties of castings;The results show that the mechanical properties and graphite morphology of the cylinder block meet the requirements,no defects are found on the surface and inside of the casting,and the quality of the cylinder block is good.
