Newest Electro-Hydraulic Servo Numerical Control Sheet Bending Machine Major Performance Characteristics: 1. Electro-hydraulic servo numerical control sheet bending machine with hgih accuracy, high-efficiency, high confuguration and high rigid. 2. Imported electro-hydraulic servo system, full closes-loop control slider in synchronization. 3. Full steel plate welding structure for the whole machie, the new technology of adopting vibration. 4. Efficiency treatment to eliminate internal stress. 5. The standard numerical control 5 axes are namely Y1, Y2(The left and right oil cylinder are in the sumultaneous movement upo and down, ), X (back gauge moves backwards), R(Back sheet moves up and down. ), V (Deflection compensation). 6. The standard numerical control system is Holland DELEM Company DA56. 7. The wedge-style deflection compensation worktable and larynx aperture deformnation mechanism is adopted to make sure bending precision. 8. The international famous -brand products of key hydraulic parts and electric components are selected. 9. The whole set of standard mould is equipped random. 10. CE standard safety protective equipment can be equipped. Control Technology The bending machine slider adopts the most advanced closed-loop electro-hydraulic servo control technology in synchronism. The grating scale install on the both sides detects the position signal and feed back the signal to numerical control of oil input in oil cylinders to control the synchronous operation of slider. Deflection Compensation of Worktable Using deflection compensation device of worktable can make you obtain accurate deflection compensation in wroktable. The device consistes of two pieces of raised sheets with several bevels and they move comparatively to form ideal curve of raised position, I nthis way, the deflection compensation between worktable and slider can be changed as per the pressure and the pre-added raised quantity of this device is controlled by numerical control system, the bending force and relevant compensation value will be automatically confrimed after the related parameters are input into the numerical control system. Back Gauge: The back gauge is driven by imported AC servo motor and transmitted by precise ball bearing and screw. It has the straight line rolling guide rail guiding, The control is credible and precision is high.
