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.

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.
Laser safety guard
Avoid operator and third party hazards
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.
