摘要
为了克服变速箱壳体压铸生产中铸件缺陷率较高的问题,运用Flow-3D软件对变速箱壳体压铸工艺进行了数值模拟。通过模拟结果分析了铸件缺陷的重点位置及成因;针对分析结果,通过降低铸件缺陷位置壁厚、增设溢流槽、扩大内浇口面积等方式对压铸工艺进行了必要的优化。优化后生产的铸件质量有了明显改善,故障率显著降低。
In order to overcome the higher defect rate of gearbox shell castings in production, the die casting process was simulated by using Flow - 3D software. The simulation results for key position and the causes of casting defects were analyzed by simulation, according to the results of the analysis, by reducing the wall thickness of casting defect position, opening the overflow trough, enlarging the gate area and so on, the die casting technology was optimized. The optimized production casting quality improves significantly, which can reduce the failure rate.
