摘要

以某机床Al-Si合金横梁为研究对象

分析横梁的结构特点、工作条件、材料特性及工艺要求

对横梁进行合理的半金属型低压铸造工艺设计。在此基础上

设计和制定相应工艺参数

并运用AnyCasting软件进行模拟分析。结果表明

该工艺不仅能满足品质要求

还能通过在不同位置处增设冷却水道并控制水流的进出顺序及时间

对工艺进行改进。优化设计能减少铸件中的缺陷

并且保证铸件有较高的工艺出品率。

Abstract

The structural characteristics

working conditions

material characteristics and technological requirements of the Al-Si alloy crossbeam for machine tool beam were analyzed.Based on the theory analysis of sand mould and metal mould low pressure casting

the reasonable semi-metal mould low pressure casting process was designed for the crossbeam.On this basis

the corresponding technological parameters were presented

and the simulation was carried out by the AnyCasting software.The results reveal that the process can not only meet the quality requirements

but also realize sequential solidification mode which is beneficial to the comprehensive performance of final castings by adjusting the position of outlet holes and cooling channels

reducing defects in castings

ensuring that the castings have the higher process yield and good quality.
