摘　　要：分析了中空结构低熔点合金制件在立式离心铸造成型过程中质点受力状态,据此指出离心成型过程出现的壁厚不均现象的原因及解决方案,并提出在旋转过程中融入摆动运动以改善壁厚不均现象的方法,分析了该方法的可行性及相关工艺参数优化,且设计一种改进型摆动离心成型设备。通过实验验证了该设备对离心成型过程中壁厚不均现象具有改善作用。the particle force state of low melting point alloy in hollow structure castings was analyzed in vertical centrifugal casting process, and the causes and solutions of the inequality phenomenon of wall thickness in centrifugal molding process were pointed out. An improved swing centrifugal molding equipment was designed. The experiments show that the equipment for centrifugal molding process has an improvement action in the inequality phenomenon of wall thickness.
