摘　　要：针对剪切线开卷机带卷甩尾易引起相邻设备损坏的问题,结合甩尾分析和冲量原理,放弃传统的减速模式,采取恒速通过模式,由换向阀和砰-砰控制优化实现定位功能。控制压头辊自动下落到开卷机和压头辊初始位置之间的黄金分割点,通过疏导通道减小甩尾幅度。控制开卷机料尾梯度张力,并采用带柔性减震器的压料机构来减弱料尾能量。实际生产表明,对甩尾进行综合治理后的系统极大地减小了高速甩尾冲击力,大大降低了对相邻设备的破坏效应,同时提高了生产效率。高速甩尾的优化治理,推进了甩尾机理的探讨和对策的研究。Aiming at the problem that the coiling tail of shearing line uncoiler is easy to cause damage to adjacent equipment,combining the tail flick analysis and impulse principle,the traditional deceleration mode is abandoned,and a constant speed passing mode is adopted.The positioning function is optimized by a reversing valve and a Bang-Bang control.It controls the pressure roller to automatically fall to the golden point between the uncoiler and the initial position of the pressure roller,reduces the tail swing amplitude through the dredging channel,controls the gradient tension of the material tail of the uncoiler and adopts a pressing mechanism with a flexible shock absorber to reduce the energy of the material tail.Actual production shows that the system after comprehensive treatment of tail flick greatly reduces the impact of high-speed tail flick,greatly reduces the destructive effect on adjacent equipment,and improves production efficiency.The optimal management of high-speed tail flick has promoted the exploration of tail flick mechanism and research on countermeasures.
