摘要
宽轨转向架摇枕是针对出口型货车开发的转向架摇枕,摇枕轴距2 210 mm,是本公司设计生产的轴距最大的摇枕,铸造难度较大;根据铸件特点及公司工艺装备现状,采用酯硬化水玻璃砂造型、制芯,对浇冒口、砂芯、冷铁进行了合理的设计,并通过对试制过程中产生的铸造缺陷进行了工艺调整,最终圆满完成了批量生产。
The broad gauge bogie bolster(bolster wheelbase:2210mm)was designed and developed by our company for exportoriented freight car,which had the biggest wheelbase.It was difficult to cast. Based on the characteristics of casting and the present situation of process and equipment,the company used the ester hardened sodium silicate sand molding and core making process,reasonablly designed the casting riser,sand core,cold iron.Through the process adjustment for the casting defects in the trial production process,the mass production successfully completed finally.
