    对挖掘机挖斗的改造设计


    工程机械挖掘机是重要的工程施工设备之一,挖掘机挖斗在工作过程中由于直接与物料接触而造成剧烈的磨损,每年造成大量钢材的耗费。目前,提高挖斗的耐磨性主要采用焊接高锰钢、耐磨钢或是堆?#25913;?#30952;材料。焊接高锰?#31181;?#35201;是利用其冲击硬化的特性,但当挖斗在低应力的磨料磨损条件下,高锰钢的加工硬化得不到体现,耐磨性得不到提高;而焊接耐磨钢或是堆?#25913;?#30952;材料却受到成本高、工艺复杂的限制。渗硼技术被认为是提高材料表面耐磨性的有效方法,但在挖斗上的应用研究目前尚处于空白阶段,研究应用渗硼技术来提高挖斗耐磨性上具有实际意义。
      (1)采用渗硼技术提高挖掘机挖斗的耐磨性;(2)在原有的渗硼膏剂中加入能显着改善渗层脆韧的稀土物质;(3)对渗硼层名义厚度进行了定义并与实测对照,误差在允许?#27573;?#20043;内;(4)采用渗硼与淬火相结合的渗淬一体化新技术,达到在强化渗层的同时也通过淬火提高基体的强度。
