浅谈由零件到铸件的关键设计过程
Brief Introduction to Critical Design Process of Castings from Parts
【摘要】 中国大学生机械工程创新创意大赛——铸造工艺设计赛在培养学生专业素养、合作精神以及提高学生综合能力等多方面有着积极的促进作用。本文作者结合参加多届铸造工艺设计赛并获奖的经验体会,借助铸钢提升箱体和球墨铸铁小型箱体两个具体案例阐述铸造工艺设计赛中基于最小铸出孔和槽、机械加工余量和起模斜度等基本设计原则将零件变为铸件的关键设计过程,以期促进提高学生在铸造工艺设计赛中的参赛水平。
【Abstract】 The Mechanical Engineering Innovation and Creativity Competition for China College Students-the Casting Process Design Competition has a positive effect on the cultivation of students’ professionalism, cooperation spirit and many comprehensive abilities. In this paper, the authors combined their experiences of participating and being awarded in the Casting Process Design Competition for several times, to illustrate the key designing process of castings from parts, which is crucial for the competition. By considering the basic three design principles, namely the treatments of minimum cast-out holes and grooves, required machining allowances(RMA) and pattern drafts, the designing processes of two castings including a cast steel lifting box and a nodular graphite cast iron small-sized box were given as typical examples, for the sake of promoting the competition levels of entry students in the Casting Process Design Competition.
