Product Description
RONGWIN factory supply WF67K-C series high accuracy electro-hydraulic CNC press brake for sale
1. The electro-hydraulic servo system adopts on-demand oil supply mode to reduce overflow and save energy by more than 30%. 2. Heat balance temperature is low, fuel tank capacity is reduced,service life of hydraulic system and components is prolonged. 3. Long interval of oil change,reduce energy waste and reduce user cost. 4. When bending the workpiece of different specification,the speed can be adjusted. 5. High precision,energy saving,environmental protection and efficiency.

    Main Motor
The electro-hydraulic servo system adopts on-demand oil supply mode to reduce overflow and save energy by more than 30%
              Hydraulic system
The digital closed-loop hydraulic system (electro-hydraulic proportional servo synchronous control system) for Rexroth bending machine, a famous brand in the world, is adopted. The system is a position control system, which can dynamically detect the synchronous error of the slide block through the grating ruler. The synchronous error of the slide block is corrected by the electro-hydraulic servo valve of the numerical control system, so that the slide block can always keep parallel with the workbench under the condition of off load. The synchronous accuracy of the slider is ≤± 0.02mm.

Independent oil tank
Over 85% of the bending machine are related to the cleanliness of the hydraulic oil passage. Our company is equipped with an independent tank with special processing technology, which can reduce the faults related to hydraulic oil to the greatest extent, ensure the stable operation of the machine tool and reduce the failure rate of the equipment.
                   Grating rule
Axis Y1, Y2 -- the left and right sides of the slide block are respectively equipped with Italian givi high-precision grating ruler (Y1, Y2), which is used to determine the exact position of the slide block and the workbench. The grating ruler is connected with the workbench through a C-shaped frame, which can eliminate the influence of the deformation of the throat of the rack on the position of the slide block to the greatest extent. The measurement accuracy will not be affected by the elastic deformation of the rack, and the accurate position data will be fed back to the CNC system In general, it can calculate the output servo valve control signals (S1, S2). Thus, the positioning accuracy of the slider is ± 0.02mm, and the repeated positioning accuracy is ± 0.01mm.

Plate support arms
Movable front material support on HIWIN linear guider, can move left and right by hand very easy

    Compensation Worktable
In order to ensure the bending accuracy of the workpiece, a mechanical deflection compensation mechanism (convex control axis w) controlled by the numerical control system is specially set up to compensate the deformation of the sliding plate and the vertical plate of the worktable under load. By using the wedge iron compensation device of the bending machine table, a group of ideal convex lines can be formed, which can realize perfect compensation in the whole length and ensure the quality of workpiece processing requirements.
