基于复杂柴油机机体特征的铸造工艺设计

Casting Process Design Based on the Characteristics of Complex Diesel Engine Bodies

为了提高V型与L型系列复杂柴油机机体柔性化制造的工艺设计效率和铸件生产质量,以典型的V型J320机体、V16机体及典型的L型K19机体、ZTD100机体为研究对象,对比研究了V型系列与L型系列复杂柴油机机体的个性特征。研究发现,两类柴油机机体在气缸排列与气缸盖数量、缸孔夹角与缸孔数量、壁连接与转角过渡等方面均有明显不同,导致工艺设计时的浇注系统类型和浇注位置放置方式等方面也存在差异。基于V型系列和L型系列复杂柴油机机体的个性化特征进行机体的铸造工艺设计,提高了机体整体铸造的工艺出品率和产品合格率。

In order to improve the process design efficiency and casting quality of the flexible manufacturing of V-type and L-type series complex diesel engine bodies,the typical V-type J320 body,V16 body,typical L-type K19 body and ZTD100 body were taken as the research objects,and the individual characteristics of V-type series and L-type series complex diesel engine bodies were investigated comparatively.It is found that the two types of diesel engine bodies are significantly different in terms of cylinder arrangement and the number of cylinder heads,cylinder bore angle and cylinder bore number,wall connection and corner transition,etc.,resulting in differences in the types of gating systems and the placement of pouring position in process design.Based on the individual characteristics of the V-type series and the L-type series complex diesel engine bodies,the casting process design of the body was carried out,which improved the process yield rate and product qualification rate of the overall casting of the body.
