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.
Key words：Plate shears；Hydraulic brake type；tool；baffle
