Kinematic And Mechanical Analysis Of The Bilateral Shear In4300mm Production Line

With the development of the production of iron and steel industry, in order to meetuser requirements for thick plate cutting edge quality, the Hobbing bilateral shear becomethe core of the whole district of the4300mm plate rolling production line of fineequipment. Compared with the traditional inclined blade shear and rotary shear, there aremany advantages in plate shear quality and efficiency of shear which the Hobbing bilateralcut in the plate. It uses multi axis and multi eccentric motion principle of rolling shear,canshear thickness of5~50mm, width of1500~4100mm plate with high precisiondouble-side fixed width shear. However, because the core technology blockade of foreignand domestic institutions of Rolling Shear less theoretical research on the existing shearburr burr pressed into the edge of the wrong knife and other issues not been fundamentallyresolved. Depth study of the Rolling Shear institutional theory, a comprehensive analysisof the the Hobbing bilateral shear mechanism of motion and force, has importanttheoretical and practical significance.This paper analyzes a rolling cut principle and characteristics of the the Hobbingbilateral, Described the4300mm production line slitting double-sided shear main structureand function,and roll cut double cut the main process parameters.Using traditional organization theory, simplified rolling-cut double side shearmechanism, and establish the overall kinematics equation, and on the cutting edge of afew key points and dynamic of the lowest point of the movement track of analysis.Use ADAMS software to simulate and analyze the bilateral shear process, Study ofrolling cut rule in different institutions and technological parameters, Obtained by themechanism and parameter optimum which shear cutting quality bestThen the establishment of the Hobbing bilateral shear process of cutting edge, cutting,a crank connecting rod mechanical model, determine the stability of rolling cut shear forceand the driving power of the theory formula. Using the formula Calculation of differentkinds of steel plate shearing thickness.
