I. The main Use and characteristic of the machine WC67Y-80T/2500 hydraulic plate press brake, adopt the welding structure of steel plate; machine tool has very good rigidity and stability; Entire frame rigidity work, is steady, safely reliable, operate convenience; through the cooperative control of electric and hydraulic system, reach ideal, fold curved effect. II. The machine explains and structure i. Slide block WC67Y-80T/2500 hydraulic plate press brake to adopt hydraulic transmission, the part of slide block forms from slide block, oil cylinder and the mechanical trimming structure of link stopper. Control oil cylinder, fix on frame, make piston (rod) drive the about sport of slide block through hydraulic pressure. ii. From the front of worktable, the button box is controlled, make motor drive stopper, around move, and from figure, show the distance that moves , its minimum reading is 0.10 millimeters (around location have route switch limit position). iii. Synchronous system This machine from turn the mechanical synchronous organization of axle and the composition of move about arm, structure is simple, it is reliable that property is stabilized, synchronous precision is high. Mechanical link stopper from generator regulation, counter shows value. iv. Back gauge mechanism Back gauge to adopt motor transmission , drive two silk rod synchronism through sprocket to move, counter show that back gauge is expected size, can is trimming by hand. III. Acceptance standard JB/T2257.1 "the technical condition of press brake” GB/TI4349 "the precision of press brake” IV. Main technical parameter 1,Nominal force 800KN 2,Length of worktable 2500mm 3,Distance between the columns 2050mm 4,Throat depth 250mm 5,Travel of slide block 100mm 6,Adjustment of slide block 80mm 7,Max opening height between the worktable and the ram 350mm 8,Main motor power 7.5KW-6 9,Oil pump 25MCY14-1B 10,Dimension 2680mm×1500mm×2300m
