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110～120 MPa，浇注温度为1 500 ℃，模具预热温度为400～425 ℃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。
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 110-120 MPa, pouring temperature of 1500 ℃ and preheating mould at 400-425 ℃, the axle box exhibits clean-smooth surface with sound structure, and defects are eliminated, greatly improving the performance.
