在风电法兰上切取纵向试样使用的刀具
摘要：
本实用新型公开了一种在风电法兰上切取纵向试样使用的刀具。属于机械制造技术领域。本实用新型的任务是：使其刀具的刀颈部分冲击切削时不易弹性变形，延长使用寿命。其技术方案要点：长方形立柱形状的刀杆(1)的顶部的右上端设置有凸出的横截面呈小梯形的小立柱形状的刀颈(101)，其刀颈(101)顶部的前面位置处设置有向下嵌入的刀头(102)，并且，刀颈(101)的后面平齐，其刀颈(101)与刀杆(1)的联接处设置有大圆弧a(111)，大圆弧b(112)；使得刀颈(101)的机械强度和刚度均得到提高，其抗冲击和抗弹性变形能力得到提高；使得刀头(102)不因较大振动而产生冲击力不均匀而过早损坏，延长了使用寿命。
摘要（英）：

The utility model discloses a cutter for cutting a longitudinal test sample on a wind power flange, and belongs to the technical field of machine manufacturing. The cutter aims at allowing difficult elastic deformation of a cutter neck part of the cutter during impact and cutting, and prolonging the service life. The cutter adopts the technical scheme that a convex and small-upright-shaped cutter neck (101) with a small trapezoidal cross section is arranged at the upper right end of the top of a rectangular-upright-shaped cutter bar (1); a cutter head (102) which is embedded downwards is arranged at the front of the top of the cutter neck (101); the back of the cutter neck (101) is flush; and a large arc a (111) and a large arc b (112) are arranged at a connecting part between the cutter neck (101) and the cutter bar (1). Therefore, the mechanical strength and the rigidity of the cutter neck (101) are improved, the impact resistance and the elastic deformation resistance of the cutter are improved, the cutter head (102) cannot be damaged early due to a nonuniform impact force generated by greater vibration, and the service life is prolonged.
