摘要
以92改进型60kg/m钢轨12号合金钢组合辙叉为研究对象,结合其在线路应用中出现的问题,从结构特点、加工方式及刀具选用等方面针对心轨、翼轨及叉跟轨等关键零件的制造工艺进行分析;分别就心轨、翼轨及叉跟轨的加工过程有针对性地提出改进方案,对合金钢组合辙叉的现行制造工艺进行优化改进;并通过加工试验,验证了工艺优化的效果。
In this paper, the improved 92-type 12# alloy steel combined frog, which is for 60kg/m steel rail, was taken as the object of study. And then in combination with the problems in its applications in railway lines, this paper analyzed the manufacture technologies of nose rail, wing rail and extended splice rail, from the aspects of structure features, manufacture method and tool selection. Further, this paper proposed some improvement programs of the manufactmre processes of nose rail, wing rail and extended splice rail respectively, and carried out the optimization to the current manufacture technology of alloy steel combined frog. Finally, by means of processing experiment, the effect of technology optimization was verified.
