摘要：近年来，工业的发展尤为迅速，其中剪板机起到了举足轻重的作用，剪板机，作为一种工业生产中对板材进行裁剪以便后续加工的机器，剪板机的使用，让工业生产更加的便捷，剪板机借助于运动的上刀片和固定的下刀片，采用合理的刀片间隙，对允许范围内的厚度的金属施加剪切力，使板材断裂分离，剪板机按传动方式的不同，分为机械和液压传动式，本次设计采用液压剪板机作为设计对象，通过对液压剪板机的结构分析，运动学分析进行设计和计算，本次设计采用双液压缸作用，对液压缸的定位和刀架调整带动上刀架进行剪切动作，让机器能达到剪切平稳，精度较高，利用后挡板装置调节板材剪切宽度，为连续剪切提高生产效率，总体对液压剪板机进行合理的布局和各部分间的安装定位、配合，使得液压剪板机能够有效而经济的运作。本次液压剪板机采用PLC控制系统，简单的操作面板，方便的操作系统让剪板机使用起来越加的便利。35044

Abstract：In recent years, the industry has witnessed rapid development, Among,the shearing machine played a important role.Shearing machine,sheet to be cut so that the subsequent processing machine as an industrial production,The use of shearing machine，industrial production is more convenient,shearing machine,by means of movement blade and fixed blade,use reasonable blade gap,exert shear force to the extent permitted by the thickness of the metal,make plate fractured separation,shearing machine according to the different transmission mode,pided into mechanical and hydraulic type,The design uses hydraulic shearing machine as a design object,Through the structure analysis by hydraulic shearing machine,Kinematic analysis, design and calculation,The design uses double hydraulic cylinder of the role，positioning of the hydraulic cylinder and turret adjustment drive the turret shearing action,machine can achieve shear stable, high precision,baffle device after use to adjust the width of the plate shear for continuous shear to improve production efficiency, the overall hydraulic shearing machine reasonable layout and the various parts of the installation location, with the effective and economic operation of hydraulic shearing machine. The Hydraulic Shearing Machine with PLC control system, simple operation panel, convenient operating system for shearing machine increasingly convenient to use.
