提高小型发动机气缸组件质量的探究

Explore of Improve the Quality of Small Engine Cylinder Components

首先分析了双金属镶铸件压铸铝合金气缸体原生产工艺上要求淬火和完全人工时效处理引起的不良后果,认为技术上、经济上不妥,使用上也不必要;其次,阐述了铝合金气缸盖低压铸造时所产生的主要缺陷及原因,并提出了改进措施,有效提高了气缸盖铸件质量。

This paper analyzes the dual metal casting die casting aluminum alloy cylinder block with the original production process requirements on quenching and completely artificial aging treatment of cause of negative consequences that technical, economic wrong, it is unnecessary to use. Then, the article analyzes the aluminum alloy cylinder head low pressure casting main defects, and from casting proeess analysis on the causes of the defects, and puts forward the countermeasure, effectively improves the quality of cylinder head castings.
