对于同一个结构紧凑,性能良好的铸件,其结构的合理与否,将极大地影响着制造工艺、生产成本以及劳动效率的优劣与高低。本文试从铸造工艺的角度,侧重以简化的拖拉机铸钢件,论述普通碳钢、砂型铸造、中小型薄壁铸件的合理结构。为了突出铸件结构的合理性,以及论述的便利起见,本文不引入工艺措施(如内外冷铁、浇注系统、冒口、工艺筋等的应用)的影响作用。
For the same compact, good performance castings, its structure is reasonable or not, will greatly affect the manufacturing process, production costs and labor efficiency of the pros and cons. In this paper, the casting process from the perspective of the focus on a simplified tractor castings, discusses the ordinary carbon steel, sand casting, small and medium-sized castings of the reasonable structure. In order to highlight the rationality of the casting structure, as well as the convenience of the discussion, this article does not introduce the impact of process measures (such as internal and external chilled iron, casting system, riser, process tendons, etc.).
