Structural Analysis and Experimental Research of an CNC Hydraulic Swing-type Plate Shears

CNC hydraulic swing-type plate shears is one of the important plate processing equipments, whose safety performance and shearing accuracy are determined by the structure of its frame and tool carrier. The current mechanical property analyses of plate shears mostly only use finite element tools and simply apply uniform load, which can not reflect true work status of the plate shears. By integrating original structures of the frame and tool carrier, two working status’ static performances of the plate shears are analyzed with finite element method in this paper, where the uniform load or moving load are separately applied according to its work statue. The analysis results are verified by the later stress-strain tests according to which structural improvements are proposed to provide basis for improving properties of the plate shears.
