摘要
选用Solidworks软件生成铸件的三维实体模型,用华铸CAE软件对球磨机端盖凝固过程进行模拟。结果表明:初始工艺中在两圈冒口中间部分及轴径处出现了显微疏松,原因是冷铁激冷度不够;利用计算机辅助技术对铸造工艺是否合理做出正确判断,克服了传统工艺设计的缺点,提高了工艺设计质量。
The solidification process, the formation mechanism and distribution law of microporosity of the ball milling machine head cover were simulated by computer. The Solidworks software was used to generate three-dimensional model of east parts and the Hua-easting software was employed to simulate the casting process. The simulated results show that significant microporosity is found in the middle of two casting heads and at the place of gudgeon journal because of insufficient chilling degree. The processing rationality is judged through the computeraided technology, by which some drawbacks of the traditional process are overcome and the process design quality is improved.
