1.刀床变形情况及修复原因1台使用多年的卡特16G型平地机由于检修不到位、操作不当,造成刮刀刀床变形,如图1所示。刀床变形后,两块刀片安装后不在一个平面上,若继续使用将大大降低刀片的使用寿命,甚至还会导致刀床的其他部位损坏。铲刀刀床变形位置位于刀床中间,正好处于箱形结构圆弧过度区域,若采用校正方法修复则难度极大。如果将该刀床报废,更换新的刀床, 1 bed deformation and repair reasons 1 Taiwan for many years the use of Carter 16G-type grader is not in place due to overhaul, improper operation, resulting in blade knife bed deformation, as shown in Figure 1. After the deformation of the knife bed, the two blades are not installed in a plane after the plane, if continued to use will greatly reduce the life of the blade, and even lead to other parts of the bed damage. Blade cutter deformation position in the middle of the knife, just in the arc over the box-shaped structure, if the correction method is extremely difficult to repair. If the bed scrapped, the replacement of a new bed,
