金属型内衬砂套离心铸造ZQCuCo3CrRE保持架工艺设计

Design of Centrifugal Casting Precoated Sand Layer for ZQCuCo3CrRE Cage

叙述了金属型内衬砂套离心铸造ZQCuCo3CrRE球轴承保持架的工艺设计原则,介绍了金属型内衬砂套工艺过程及其特点,分析了球轴承保持架铸件产生缺陷的要因及预防措施。结果表明,对于单件小批量生产的异型球轴承保持架采用金属型内衬砂套离心铸造工艺,能保证铸件质量,提高生产效率。

This paper describes the process design principle of ZQCuCo3CrRE ball bearing cage centrifugal casting that adopts ordinary clay precoated sand sleeves. The process and characteristics of the precoated sand sleeves at metal mold inner surface .were introduced. The causes and preventive measures of defects on ball bearing cage were analyzed. The results show that a single piece of small batch production of special shaped ball bearing cage centrifugal casting with ordinary clay covered sand sleeves process can ensure the quality of castings and improve production efficiency.
