文档介绍：辽宁科技大学本科生毕业设计(论文) 第 I页 2150 滚筒式切头飞剪机设计摘要切头飞剪机是热连轧生产线上的单体设备,它的用途是切头、切尾,出现卡钢事故时, 将轧件剪断,处理卡钢事故。有时也可切定尺,检查轧件的质量。本设计是 2150 滚筒式切头飞剪,主要用于切头和切尾,采用双电机驱动,剪切机构的传动方式是转鼓式, 上下转鼓同步转动,减少了动力矩,提高了剪切质量。在该设计中,主要进行剪切力的计算,选择主电机的容量,进行转鼓轴、齿轮的设计计算,进行剪切机构刀片的设计, 剪切侧间隙调整装置的设计,对飞剪机进行润滑方法的选择,试车和控制要求,采用环保措施,保证可靠性经济性好,具有显著的经济效益。2150 切头飞剪是热连轧厂常用的剪切设备。关键词: 飞剪机;滚筒式;切头;切尾辽宁科技大学本科生毕业设计(论文) 第 II页 Design of the 2150 Drum Type Crop Shear Abstract Crop shear is the monomer equipment on the hot rolling production line,which is used to cut head and tail of rolling. When the steel can not travel as usual ,it can be used to cut the stock and to avoid an accident. Sometimes, it's also used to cutting stock into desired sectional lengths and to check the quality of the rolled piece. This design is the design of the 2150 drum type crop shear, which is drived by two motor. It is an object of this designto reduce remarkably the power consumption in flyingshears of the instant character by eliminating acceleration and deceleration of the shear drums for each shearing operation and improve the section quality. In this design, it is important to calculate shear stress ,select main motor ,design and calculate drum axis and gears. In this paper, I also give the design of shear blade and adjusting device for the gap between the upper and lower shear drums. Besides, selection of lubrication and testing and control requirements are also necessary. In order to get significant economic benefits, we must take environmental measures when producing. Nowadays, the 2150 drum type crop shear is used in continuous hot-strip mills generally.
