发动机零部件的铸造工艺分析及工序控制

Casting Process Analysis and Procedure Control of Engine Parts

以发动机前油封零件为例,对其压铸难点进行了深入剖析,详细阐述了金属熔炼、压铸、机加工、清洗以及密封性检测等工序的控制要点。实际应用表明:严格控制各工序,能有效降低返工率,提高铸件品质,具有直接的经济效益。

Taking engine front flange part as an example, its die-casting difficulty was thoroughly analyzed. The procedure control points of metal smelting, die-casting process, machining, washing, tightness testing and so on were elaborated. Practical application shows that： strict control of the each procedure can effectively reduce rework rate and improvethe casting quality, which obtains economic benefit directly.
