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。

Abstract

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.
