HANS-Press Brake Press Brake MAIN FEATURES • Up-acting hydraulic servo system • Backgauge system • Perfect mechanical compensation (angle-adjustment) • Crowning system Up-acting servo hydraulic system The up-acting hydraulic system drives the upper beam doing an up-and-down movement, but the lower worktable stays fixed. The bending force generated by applying pressure over hydraulic cylinders. The precise closed-loop control composed of an electro-hydraulic servo valve and linear encoder can simultaneously control the pressurization of the main cylinders on both sides. The system feedback data enables the slider to be accurately controlled so that the bending accuracy and repeatability is high. Backgauge system Backgauge system options: • 4 Axis CNC Back Gauge for YI, Y2, X, R, V-Axis(crowning axis) • 6 Axis CNC Back Gauge for YI, Y2, X, Z1, Z2, R, V-Axis (crowning axis) Perfect mechanical compensation (angle-adjustment) Crowning is how a press brake compensates for machine deflection. The crowing system counts the amount of deflection and compensates it by controlling the movement of movable wedges seated on the lower worktable. The movable wedges in the middle of the worktable create a slope to compensates for the bed deflection and the beam under different bending forces, maximum reduces a gap between workpiece and wedges. 3D graphical programming available CNC system The bending machine is equipped with DELEM bending machine numerical control system DA58T / DA66T. The synchronization of the left and right cylinders control through 4 + 1 axis / 6 + 1 axis, which achieves efficient and high precision machining.
