摘要

通过二元影像测量仪观察锯条干喷处理后的表面压应力、覆盖率、齿尖状况

不磨合锯切GCr15棒材的齿尖崩刃情况和锯切45

钢和空转疲劳寿命试验研究表面处理干喷砂工艺参数（压缩空气压力0.1~0.4MPa

运行速度4~1m/min）对M42（/%:1.08C，1.5W，9.4Mo，3.8Cr，1.2V，8.0Co）-D6A（/%:0.48C，1.0Mo，1.1Cr，0.1V，0.6Ni）双金属带锯条性能的影响。结果表明

锯条经合适的参数-压缩空气压力0.3MPa和运行速度3m/min

背部表面覆盖率达到100%

干喷后

齿尖形成稳定的圆角

承受切割和振动的冲击力

以提高锯条齿尖的耐磨性

齿部的平均使用寿命提高66%

背部疲劳试验寿命提高45%~70%。

Abstract

The influence of parameters of shot peening process for surface treatment (compressed air pressure 0.1~0.4MPa

running speed 4~1m/min) on performance of M42 (/% ： 1.08C

1.5W

9.4Mo

3.8Cr

1.2V

8.0Co) - D6A (/% : 0.48C

1.0Mo

1.1Cr

0.1V

0.6Ni) bi-metal band-saw blade has been studied by binary image measuring instrument to observe surface compression stress

blade back shot peening coverage rate and tooth tip condition

and tooth tip fracture condition as non-fitting cutting steel GCrl5 bar products and fatigue life of blade back with cutting steel 0.45C and idling fatigue test after shot peening treatment of blade. The results show that with suitable shot peening process- compressed air pressure 0.3 MPa

running speed 3mm/min and blade back shot peening coverage rate reach 100%

after shot peening the stable rounded comer of tooth tip is formed to bear the impact force produced by cutting and vibrating and improve the wear resistance of band-saw blade tooth tip

the average service life of teeth increases by 66% and the tested fatigue life of band-saw blade back increases by 45%~70%.
