IMPLEMENT CUTTING EDGE WITH BRAZED WHITE CAST IRON TEETH
A cutting edge component for a work tool on an earth-moving machine may include a longitudinally-extending wear component and a support surface connectable to a moldboard of the earth-moving machine.The wear component may include at least one wear portion connected to the support surface, and the at least one wear portion may form at least one ground engaging edge. The at least one wear portion may include a mild steel body and a plurality of longitudinally-spaced white cast iron teeth vacuum brazed along a distal, ground engaging edge of the mild steel body. The plurality of teeth may each be shaped with two intersecting substantially planar surfaces arranged to mate with at least a surface extending between the distal, ground engaging edge and at least one of a rearward-facing surface of the mild steel body and a front-facing surface of the mild steel body on at least one of a side of the mild steel body facing away from a direction of travel of the machine and a side of the mild steel body facing in the direction of travel of the machine to form a brazed joint. Each tooth may include a material directing feature defined in a front-facing surface of each tooth when the tooth isbrazed to the mild steel body.
本发明提供了一种用于推土机上的作业工具的切削刃部件，所述切削刃部件可以包括纵向延伸的磨损部件和可连接到推土机的犁板的支撑表面。磨损部件可包括连接到支撑表面的至少一个磨损部分，且至少一个磨损部分可形成至少一个地面接合边缘。至少一个磨损部分可包括软钢主体和多个纵向间隔开的白口铸铁齿，沿着软钢主体的远侧地面接合边缘真空钎焊所述多个纵向间隔开的白口铸铁齿。所述多个齿可各自成形为具有两个相交的基本上平坦的表面，所述两个相交的基本上平坦的表面被布置成与至少一个表面配合以形成钎焊接头，所述至少一个表面在所述远侧地面接合边缘与在背离所述机器的行进方向的软钢主体的一侧和面向所述机器的行进方向的软钢主体的一侧中的至少一者上的所述软钢主体的面向后的表面和所述软钢主体的面向前的表面中的至少一者之间延伸。每个齿可包括当所述齿被钎焊到所述软钢主体时在每个齿的面向前的表面中限定的材料引导特征。
