对某型承力机匣气腔成型技术进行研究,确定了借助陶瓷型芯形成承力机匣气腔。针对陶瓷型芯成型和使用技术进行了一系列工艺的研究和探索,合理设计了所用陶瓷型芯的结构,确定了生产用陶瓷型芯、可行的工艺方法和工艺参数,成功铸造出了气腔尺寸和表面质量满足使用要求的承力机匣整体精铸件。 The research on the air cavity forming technology of a certain type of bearing frame is made, and the air cavity of the bearing frame is formed by means of the ceramic core. A series of technological research and exploration were carried out according to the forming and using technology of ceramic core. The structure of the ceramic core used was reasonably designed, the ceramic cores for production were confirmed, the feasible technological methods and technological parameters were determined, Dimension and surface quality to meet the requirements of the bearing casing as a whole castings.
