摘要

通过对RLS轴承架的结构分析

采用精密铸造工艺

蜡模制作采用先分后合的工艺方法

解决难于取模的问题

铸件通过浇注后用压缩空气或冷水对铸件的中间法兰与R10mm凸台和中间的圆柱体的结合部位进行强行快速冷却

避免了铸造缺陷的产生:在后处理过程中

在轴承架铸件碎壳、抛丸、酸洗钝化、热处理等工艺过程中

通过工艺手段而控制了铸件的变形。

Abstract

Structure characteristics of RLS bearing bracket was analyzed

and the wax pattern was made through splitting wax pattern and wax mold firstly and then integrating.The casting defects in the RLS bearing bracket were eliminated by rapidly forced cooling to middle flange and combined position of R10 and middle cylinder with compressed air or cooling water.The casting deformation was controlled by processing control in process of shell-broke

blasting and heat treatment and so on.
