摘要
大型数控龙门加工中心滑枕铸件结构复杂,尺寸精度、基体组织及表面质量要求较高,造型、浇注过程中砂芯易变形、断裂。本文从砂芯设计、浇注系统设计、合金成分控制等多方面出发,给出了较为成熟的制作方案及控制要点,成功生产出大型HT300滑枕铸件,铸件品质满足机床设计要求。
Ram is one of the key components of the large-scale CNC machine tools. The structure of ram is complex, the requirements of dimensional precision, matrix microstructure and surface quality are higher. The sand core deformation and fracture easily occurred in molding and pouring process. This paper provides the more mature production plan or control methods of molding design, gating system design, chemical composition control of molten iron, as well as the appropriate process parameters. The large-scale HT300 ram casting has been successfully manufactured, and casting quality meets the requirements of machine design.
