50*1560铸坯摆式剪切机设计 摘 要 50*1560铸坯摆式剪切机是安装在薄板坯连铸机扇形段的出口和加热炉的入口之间，用于把连铸机出来的热板坯根据一定的尺度进行分段剪切后输送到加热炉的。 首先，本文讨论了连铸连轧技术在国内外的发展；较完整地介绍了剪切机的基本知识，以及摆式剪的结构特点和研究的内容与方法；比较了三种摆式剪设计方案，选择了一种较为合适的方案来设计。然后，根据结构参数对摆式剪进行运动学分析和力能参数的计算，从而预选了电动机。最后，对偏心轴进行弯扭强度的校核，校核了危险断面，判断了预选的电动机是否合适；详细讲述了设备的安装检测、维修、状态监测和润滑的基本内容。 通过以上工作，本次毕业设计作出了一种结构较为完整的摆式剪切机。 关键词：剪切机，摆动，主传动 The design of 50 * 1560 billet shearing tilting machine Abstract The 50 * 1560 billet shearing tilting machine is installed on between the export of the thin slab continuous casting machine and the entrance of the furnace.It is used to transfer the heat slab which is shared according to certain sub-scale from the continuous casting machine to the furnace.  First of all, this paper discussed the continuous casting and rolling technology development at home and abroad; a more complete description of the basic knowledge of shear machine and the structural characteristics of tilting and research contents and methods; compared the design of three tilting shear program, select a more appropriate program design. Then, pre-select the motor according to the calculation of force energy parameters and the kinematics of the swing analysis based on structural parameters.Finally, check the bending and torsion strength on the eccentric axis, check a dangerous cross-section to determine the suitability of the pre-selection of the motor; details about the basic content of the installation, maintenance, monitoring condition and lubrication of detection equipment. Through the above-mentioned work, the graduate design a more comprehensive structure of tilting shears.
