1,main construction steel-welded construction, vibration to eliminate stress with high strength and good rigidity 2,advanced technology 2-1, adopted advanced hydraulic system reduced the pipe joints steadiness and reliability 2-2,the setting surface of upper blade is screw this keep homogeneity of blade clearance while shearing the plate. 2-3,strore engage return back quickly. 2-4,upper blade is rhombus and rectangle for the down blade. Its material is 6CrW2Si with good hardness and long age. 2-5,the blade clearance can adjusted by hand wheel and the number marked on the plate. Adjust quickly and easily with good credibility. 2-6, blade stroke adjusted stepless, the pressure can adjusted according to the thickness automatically. 2-7,it has equipped with light to overlapping the draw line on the plate. gauge size and cutting times adopt staff counter ,operate very easy. 2-8,protective grating controlled by electrical system. 2-9,support device with ball to reduce the damage of the board. 2-11,oil cylinder used No 45 steel substrate inside hole boring precise. 2-12, piston rod: used No 45 steel substrate plating Chromium outside. 3main parts : A, main electrical parts supply by siemens B, hydraulic system : China C, seals : Japan D, main motor: China E, blade: China material 6CrW2Si 4,inspect standard: National standard : GB/T 14349-93 5,documents additional: 5-1,operation manual (hydraulic system, electricity principle drawing and foundation drawing ) 5-2,quality certification 5-3,packing list(include the spare parts) 6,sell service: guarantee :one year as from the date of installation and acceptance.
