摘　　要：冷剪机是棒材生产线精整区域的关键设备,冷剪机的剪切能力高低及设备运行状况好坏是制约轧钢产能的关键之一。目前国内的棒材生产线大多投产年份较早,冷剪机在建设时设计产能较低,随着轧制线产能的不断提升,轧制节奏加快,冷剪机原有设计产能已较难满足轧制线的需求,同时由于冷剪机一般设计采用C型结构,存在剪体刚度不够、壳体开裂等问题,无法保证剪切能力及剪切质量。本文通过对冷剪机采用龙门框式改造,解决冷剪机刚度不够壳体易开裂问题,保障了冷剪机的剪切能力和剪切质量。Cold shearing machine is the key equipment in the finishing area of the steel bar line.The shearing capacity of the cold shearing machine and the running condition of the equipment are the key factors which restrict the rolling output.Most of the current domestic steel bar lines were built many years ago,so that the cold shearing machine in the construction design capacity is low.With the continuous improvement of the production capacity of the rolling line and the acceleration of the rolling pace,the original design capacity of the cold shear has been difficult to meet the needs of the rolling line.At the same time,because the cold shear is generally designed with C-type structure,there are problems such as insufficient shear stiffness and shell cracking,which can not ensure the shear capacity and shear quality.In this paper,through the gantry frame transformation of the cold shear,the problem of insufficient stiffness and easy cracking of the shell of the cold shear are solved,and the shear capacity and shear quality of the cold shear are guaranteed.
