Main uses and product features

We67k series electro-hydraulic servo numerical control bending machine integrates numerical control technology, servo and hydraulic technology. The slider moves up and down periodically through the action of control valve, and the movement is measured by the grating reading on both sides of the machine. DNC controls the openings of the two valves of the left and right oil cylinders. If necessary, the flow in the oil cylinder can be redistributed by the servo valve to make the slider move in a straight line in the vertical direction. The amount of movement is determined by the newly measured pulse number.

The electro-hydraulic servo CNC bending machine has high productivity and high working accuracy for bending metal sheet. When bending sheet with different thickness, the "V" groove with different opening size distributed on the lower die should be selected. Generally, the opening size of "V" groove should be greater than 8 If the upper and lower dies of different shapes are used, the workpieces of various shapes can be bent. At the same time, the bending force can be calculated by the bending force table (see machine tool) or bending calculation formula. After one stroke of the slider, the sheet metal can be bent once, and the workpiece with complex shape can be obtained after multiple bends. Electro hydraulic servo CNC bending machine adopts steel plate welding body, which has enough strength and rigidity. Hydraulic transmission ensures that it has automatic overload protection when it works. In addition, the machine has the characteristics of stable operation, convenient operation, safe and reliable. The machine is equipped with deflection compensation mechanism, which compensates the deflection produced by the force of the workbench and slider when bending the plate, so as to ensure a higher working efficiency Accuracy.

The machine adopts the advanced electro-hydraulic servo automatic control system, the positioning of the slider is accurate, and the operation is stable. The stroke and position of the slider can be adjusted according to the needs of the bending process, and it has the action specification of inching, which is convenient for die test and adjustment. With advanced technology and reliable performance, this machine is one of the ideal sheet metal forming equipment. It is widely used in flying machine

Machinery, automobile, shipbuilding, machinery and other operations, high production efficiency.

Technical characteristics

1. Both sides of the main cylinder synchronous use of imported electro-hydraulic servo valve and imported grating ruler to form a closed-loop control, accurate feedback, accurate operation of the slider, so that the bending accuracy, slider repeat positioning accuracy is high. The deviation is less than or equal to 0.05mm.

2. The repeated positioning accuracy of the back stop is ≤ 0.05mm, and the functional parts in the back stop are national or imported parts, which ensures the material blocking accuracy of the machine.

3. The fuselage adopts split steel plate welding structure. After vibration aging treatment, the deformation caused by welding stress and processing stress is removed, which ensures the accuracy and stability of the machine tool.

4. The fuselage, slide block and other important parts are analyzed and manufactured by finite element analysis software, which can ensure the working stability of the machine tool.

5. The hydraulic system adopts the imported integrated control system, reduces the pipeline installation, improves the working stability of the machine tool, and has beautiful and simple appearance.

6. The digital control system adopts the Dutch delem da53t system.

7. Both sides of the fuselage are equipped with C-shaped plates, and the high-precision grating ruler is installed on the C-shaped plate, so as to avoid the influence of fuselage deformation on the bending accuracy during bending.

8. Oil cylinders processed by professional manufacturers, complete sets of imported seals, and pipe joints imported from Germany EMB can overcome oil leakage.
