摘要
铝合金电机壳结构复杂,铸造难度大。介绍了电机壳的结构特点并对电机壳常见铸造缺陷进行了识别。在此基础上,探讨了电机壳的典型砂型铸造工艺方案。对重力铸造、低压铸造,低压浇注翻转凝固和倾转铸造4种铸造方式生产电机壳的可行性进行了分析,并着重论述了低压铸造生产电机壳的浇注系统计和冒口设计。研究表明,上述4中铸造方式均可用于电机壳的生产,具体工艺选取则取决于产品结构特点,并借助计算机模拟仿真进行工艺可行性的评估。并论述了计算机模拟技术在电机壳铸造工艺开发中的应用。
Aluminum alloy motor shell is complicated in structure and difficult to cast.This paper introduces the structural characteristics of the motor shell and identifies the common casting defects of the motor shell.On this basis,the typical sand casting process scheme of motor shell is discussed.This paper analyzes the feasibility of gravity casting,low pressure sand casting,low pressure casting with over flow,and tilt casting,and focuses on the gate design and riser design of low pressure sand casting.The research shows that the above four casting methods can be used in the production of motor shell,the specific process selection depends on the characteristics of product structure,and the feasibility of the process is evaluated by computer simulation.This paper also discusses the application of computer simulation technology in the development of casting process of motor shell.
