摘　　要：在生产现场采用跟踪统计方法,归纳分析铁基非晶纳米晶合金带材滚剪加工过程以及滚剪刀耐用度、刀具刃磨等问题,统计分析不同宽度滚剪刀的加工情况发现,滚剪刀有效工作时间比率为65%~88%,平均有效工作时间比率为76.1%,有效工作时间不稳定;滚剪刀剪切行程处于3700~4200m之间,平均剪切行程为3839.74m,刀具耐用度存在较大差异,剪切宽度越大滚剪刀耐用度越长;滚剪刀刃磨时刀具径向去除量在80~150μm之间,平均刃磨去除量为106μm,刀具刃磨工艺对刀具耐用度有决定性影响。最后针对滚剪刀磨损检测问题,提出采用声发射信号对滚剪刀状态进行在线检测的技术方案。By using tracking statistics on the production workshop,the rolling shear process,durability,tool sharpening and other issues during the rolling shear processing of iron-based amorphous nanocrystalline alloy strips are summarized and analyzed.Statistically analysis of different widths of rolling shears is done,it is found that the effective working time ratio of rolling shears ranged from 65%to 88%,with an average effective working time ratio of 76.1%,and the effective working time is unstable;the shearing mileage of rolling shears is between 3700m and 4200m,with an average shearing mileage of 3839.74m,and there is a large difference in tool durability,with the larger the shearing width of rolling shears,the longer the tool durability.The greater the shear width,the longer the durability;the radial removal of the tool during sharpening of the rolling shears ranges from 80μm to 150μm,with an average sharpening removal of 106μm,and the tool sharpening process has a decisive impact on the tool durability;finally,for the wear detection problem of the rolling shears,an acoustic emission signal can be used to conduct online inspection of the condition of the rolling shears.
