摘要
大同步带轮是医用CT机上重要的部件之一,目前多采用砂型铸造,产品合格率低。为解决这一问题,本课题采用了金属型和砂芯联合使用的铸造方案,使用Pro/E软件完成对铸件的实体造型,根据金属型铸造特点,利用Z-CAST铸造工艺数值模拟软件,研究大同步带轮铸造充型及凝固过程,分析了铸造工艺的合理性,最终提出了优化后的铸造工艺方案。
The in-phase annulus is one of the critical parts of X-ray medical treatment equipment.At present,sand casting is adopted mostly,which makes casting yield low and cost high.Aiming to resolving the problem,regarding the in-phase annulus as an object,permanent mold casting with sand core is adopted.Base on the 3-D mold from Pro/E and the characteristics of permanent mold casting fluid flow,filling and solidification process is investigated to optimize its foundry technology from casting process numerical simulation software named Z-CAST.
