螺旋剪刃间隙自动调节滚筒式飞剪的设计计算

Design and calculation of the drum shear with automatically adjusted spiral knives gap

滚筒式飞剪是高速连轧机组中的关键设备,以往均由国外设备供应商提供。以梅钢1 420 mm酸轧联合机组自主集成创新建设为契机,完成了国内首台剪刃间隙自动调节的螺旋剪刃滚筒式飞剪研制。对该飞剪研制初期的设计计算进行了总结;重点对飞剪工作制度及其与轧机全线的匹配性、剪切力能参数和剪切电机选择、剪刃间隙自动调节装置等方面进行阐述,介绍了相关的设计计算和数据。在实际生产中得到了验证,达到了设计要求。

Drum shear is the key equipment in a high-speed continuous roiling mill. It used to be provided by foreign equipments suppliers. It was an independent innovation opportunity to build the 1 420 mm PL-TCM line of Meishan Steel, and during that period, the development of the first domestic drum shear with automatically adjusted spiral knives gap was completed. This paper sums up the design and calculation at the initial development period, focuses on the working system of the drum shears, the matching between the drum shear and the whole rolling line, energy parameters of the shear force, the choosing process of the motor and shear, the automatic adjustment device for the gap between shear knives. The paper also introduces the related design, calculation and data. In the actual production, all these have been verified and reached the design requirements.
