Main Motor

The electro-hydraulic servo system adopts on-demand oil supply mode to reduce overflow and save energy

by more than 30%

Independent 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.

  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.

High quality fast clamps

Easy to operate, time-saving and labor-saving

 High quality bending die

The integral quenching precision CNC bending die is durable

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.

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.
