摘　　要：模切机是重要的印后加工设备,其两个重要的性能指标是模切速度和模切精度。首先,介绍卧式平压平模切机和模切单元的组成与工作原理,并详细介绍模切单元双肘杆机构;其次,概述影响模切精度的因素;最后,应用ANSYS对模切单元进行模态分析,发现蜗轮蜗杆啮合产生的激振频率会造成设备振动而影响模切精度,因此开机与运行过程中的频率需避免与激振频率重合。Die cutting machine is an important post-press processing equipment,in which die cutting speed and die-cutting accuracy are two important performance indicators.Firstly,the composition and working principle of horizontal flat die cuttnig machine and die cutting unit are introduced,and the double elbow bar mechanism of die cutting unit is introduced in detail,h te modal analysis of die cutting unit is carried out by ANSYS,and it is found that the exciting frequency produced by the meshing of worm and worm can cause the equipment vibration and affect the die cutting precision,therefore,it is necessary to avoid the frequency coincidence with the excitation frequency during the start-up and operation.
