CUTTING EDGE FOR MOTOR GRADER

摘要

PROBLEM TO BE SOLVED: To extend a life by fusing tungsten carbide at the edge part of a cutting edge. ;SOLUTION: A front is bent in the height direction, and the fusion part 2 of tungsten carbide is provided at the cutting edge 1 of a special steel-made flat blade or the edge part of the lower part of the cutting edge of a comb blade having a bolt hole 5 for attaching to a motor grader. Next, the tungsten carbide fusion part 2, for example, is formed by an arc padding welding method. Therefore strength can be increased by leaps and bounds, in addition, a life can be extended, the number of the exchange of the blade can be reduced, and in addition, working efficiency of leveling of ground, snow removing, snow pressed face excavation and the like can be improved.;COPYRIGHT: (C)1999,JPO
