摘　　要：采用一般砂芯涂料生产4JB1汽车发动机缸体、缸盖时,在缸体、缸盖内腔会有大量粘砂,使得汽缸导热性降低,从而带来许多负效应。实验研究表明,采用合理的喷丸清理工艺,对4JB1发动机缸体、缸盖铸件内腔粘砂进行清理,可取得较好的效果。所以有必要在此基础上建立自动化程度较高的缸体、缸盖喷丸清理线来适应大批量生产的需要。介绍了解决缸盖、缸体清理线布置的几个关键技术问题、清理流程、布置及特点。When general sand core paint is utilized for producing 4JB1 automobile＇s engine cylinder, a large amount of adhering sand will be generated in engine＇s cylinder lid and cylinder body, which thus will lower thermal conductivity of cylinder and accordingly bring forth numerous negative effects. The experiment and research show that better effects can be achieved if the reasonable blasting cleaning process is adopted for removing adhering sand inside 4JB1 automobile＇s engine cyliflder casting. So building automatic shot-blasting cleaning line for cylinder body and cylinder lid is necessary in the mass-production. Then key technology, cleaning flow sheet and the layout of cleaning line for cylinder body and cylinder lid is introduced.
