摘要
以HBW160床身原有铸造参数为基础,利用AnyCasting软件模拟了床身的充型和凝固过程。依据计算结果和缺陷发生规律,分析了铸件内部的温度场和流场。试验表明,侧壁凸台处因补缩通道阻塞而产生了缩孔倾向。采用工艺优化,增大顶部冒口的尺寸,在厚大部位添加冷铁,可有效地消除铸件内部可能出现的缩孔缺陷,满足实际生产的要求。
On the basis of the original casting parameters of HBW160 machine tool bed,the filling and solidification process were simulated by the software Any Casting.Based on the calculation results and the principle of defect generation,the temperature field and flow field inside the cast were analyzed.The result show that the shrinkage tendency produces in the boss on the side wall because of the feeding channel blocked.By process optimization to increase the size of the top riser and the number of cold iron in thick parts can effectively eliminate internal shrinkage defects,so as to meet the requirements of the production.
