摘要

针对轨道客车转向架轴箱砂型铸件存在的夹砂、气孔等缺陷

对轴箱采用了半固态挤压铸造技术。并利用Pro/E软件进行了模具设计

对其工艺进行了研究分析

利用Ansys软件对其成形过程进行了模拟

并进行了试验验证。结果表明

在比压为110

20MPa

浇注温度为1 500℃

模具预热温度为400

25℃的条件下

获得的铸件表面光洁完整、组织致密

缺陷基本消除

性能得到提高。

Abstract

Aiming at inclusion and gas holes in sand casting axle box of the bogie for passenger train

semi-solid extrusion forming was investigated.Mould was designed by the Pro/E

and the process was analyzed.Meanwhile

the filling process was simulated by the Ansys software

and the trial-product was conducted.The results indicate that with pressure of 110

20MPa

pouring temperature of 1 500 ℃and preheating mould at 400

25 ℃

the axle box exhibits clean-smooth surface with sound structure

and defects are eliminated

greatly improving the performance.
