摘　　要：铝合金板带冷轧过程中需用圆盘剪切边,阐述了板带剪切过程的三个阶段:弹性变形、塑性变形和断裂;剪切裂纹的形成与发展。分析了剪刃侧隙大小、剪刃重合度和刃口对板带切边质量的影响,以及常见剪切缺陷产生的原因及其避免方法。During the process of cold rolling,aluminum sheet and strip should be edge-trimmed by the rotary trimmer.Three stages of edge trimming are described： elastic deformation,plastic deformation and cracking.Crack formation and development are also described.It is analyzed that effects of the size of side clearance of blade edges,overlap degree of blade edges and edge itself on side trimming quality of the sheet and strip.It is further analyzed that the reason for causing the common trimming-defects and methods for avoiding said defects.
