内容简介：

1.5兆牛摆动剪切机构设计摘要1.5兆牛摆动剪切机是安装在500型钢热连机前，用于切头切尾和卡钢事故的处理剪。随着国民经济的发展，对型钢产品数量的要求更高。本设计为型钢设计切头的摆动剪，设计中对摆动剪的局部做了改进。首先，本文讨论了型钢轧机在国民经济中的地位，并对300/500机组平面布置示意图的概况进行了整体的介绍。并介绍了摆动剪的结构特点和研究的内容与方法。根据现有设备状况，对设备生产中存在的问题进行分析，对主要部件结构做了合理的选用。然后，根据机组原始参数初选主电机容量，对其进行发热校核和过载校核，对主要零件进行强度校核。对齿轮做了强度计算，对曲轴计算了弯曲应力，弯扭合成应力；校核了危险断面；以及滑块损坏的改进设计及润滑方法，简单计算摆动剪的可靠性和经济评价。通过以上工作，1.5兆牛摆动剪切机在使用寿命、产品质量理论上应该有一定的提高。设计内容有实际价值。该剪作为加热炉前方坯切头飞剪。关键词：剪切机，摆动，主传动A Design of 1.5 Swing Scissors1.5 swing scissors is installed before the 500 sharp steel of hot continuous rolling mills, which is used to cut the head and end of the steel and deal with the jamming of the steels.With the development of the national economy, the request of the sharp steelss quality is higher than before. In the thesis, the cutting of the head of the 1.5 swing scissors is researched, and makes some improvments of partial strcture.First, the thesis has discussed the position of the rolling mill of sharp steel in the national economy, and makes the general instruction for 300/500 unit plane arrangement. Next, introducing the structural characteristic of the swing cutting and the method and content of the research .According to exising equipment condition, analysing the exist problem in equipment production, the strcture of the major parts are reasonable to choosed. Then,according to the primitive parameter of the unit, I primarily choose the capacity of the main motor, and make the heat examination and overload examination, choose if satisfying the requirement, otherwise choose again until the examination is satisfyed. I make the strength examination for major element. As to gears, I make the strength calulation; as to crank, I caculated the curving stress and the crooked synthesis stress, examinationing the dangerous cross section, as well as the improment of the damages of the slide and the method of lubrication. Finally I caculated the economy appraisal and the reliablity of swing scissors.Through the work of this thesis, 1.5 swing scissors should certain raise in service life and product
