摘要
铝扁锭锯切机组在锯切时其带锯条受到拉伸、扭转和弯曲载荷的作用,这些载荷在带锯条上产生了交变应力,经过多次循环运转后带锯条会产生疲劳断裂。通过观察机组的操作情况并结合断裂力学相关公式,得出带锯条使用寿命过短的原因是由于操作、维护不当使得带锯条应力幅异常增大所致。由此提出了提高带锯条使用寿命的措施。
It is indicated that the short service life of band saw blade of cutting unit for aluminum slab ingot is due to improper operation and maintenance by observing operation conditions and combining with related fracture mechanics formula. Thus how to increase the service life of band saw blade is put forward.
