WF67K-E 200 Ton 3200 Electro-hydraulic Synchronous CNC Bending Machine  

1.Adopt overall welding,after the aging treatment,then adopt overall processing methods to ensure the

accuracy and reliability of the whole machine. 2.Hydraulic system adopts Germany Rexroth closed-loop control mode,controlled by the CNC system of

Netherlands Delem.The up chamber internal of fuel tank equipped with Roxroth filling valve.The fuel tank

of the upper install Rexroth synchronization valve block,grating imported from Germany to detection the

balance of slider up and down and the uniformity of pressure,to ensure the synchronization of the slider

and bending accuracy.

3.Just enter the sheet thickness,width,tensile strength and bending angle,the system will automatically

control the pressure and the alider motion,without manual adjustment. 4.Workbench adopts mechanical torsion compensation system,as the mechanical compensation point,

so the mechanical compensation effect is far greater than the hydraulic compensation,to achieve effective

compensation without blind spots and improve the bending accuracy,to ensure the long-term stability. 5.Back gauge with digital servo motor drive,the full import of precision ball screw drive,and liner guide-

oriented,ensure back gauge accuracy and strong repeatability, also according to user needs adopt more

complete multiple back gauge axis of the back gauge institutions.

6.Energy saving,environmental protection and high efficiency CNC hydraulic press bender.

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.

Main Motor

Hydraulic valve Pump

High quality fast clamps

Easy to operate, time-saving and labor-saving 

Schneider Electrics

France brand

 High quality bending die

The integral quenching precision CNC bending die is durable

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.

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.
