CNC Tandem Hydraulic Press Brake

Equipment model: 2-WE67K-400/6000

Application: Street light pole, high pole light pole, monitoring pole, sign pole production

I. Main technical parameters of the machine:

Y1, Y2 axis-Grating scales (Y1, Y2) on both sides of the slider control the numerical control axis of the cylinders on both sides.

Deflection compensation mechanism of V-axis and worktable

Slide positioning accuracy ±0.02mm

Slide repeated positioning accuracy ±0.01mm

Second, the main performance and characteristics of electro-hydraulic synchronous CNC bending machine:

1. The frame is composed of oil tank, tray, support block, workbench, left and right wallboard and slider, which ensures the structural strength of the frame, and adopts vibration stress relief method, and the surface is sandblasted.

2, machine tool synchronization principle: the application of electro-hydraulic servo proportional valve to ensure dual-machine synchronization, the use of BoschRexroth company's electro-hydraulic servo proportional valve, its performance characteristics are with high control force continuous action electromagnet, mechanical motion pair in the friction is very small and has a fast working characteristics of precision electronic amplifier. A grating ruler is respectively arranged at both ends of the main board of the worktable, the stroke position and the synchronous error of the sliding block are continuously reflected, and the two difference values are sent into a numerical control system to control the electro-hydraulic servo proportional valve so that the single machine and the double cylinders are synchronized. Because the grating ruler is not directly arranged on the frame wallboard but is arranged on the C-shaped frame fixed on the main board of the workbench, and the workbench is taken as a reference point, the deformation of the slide block and the frame under load does not affect the measurement and control precision of the grating ruler. When the two machines are linked, the synchronization information of the two machines is changed into an electric signal and transmitted to the synchronization board and the control system through the differential potentiometer installed between the two sliders, and the electro-hydraulic servo proportional valve is controlled by the Bosch Rexroth amplifier board to make the two machines operate synchronously.

3, DELEM CNC system can automatically calculate and adjust the bending force. It can automatically calculate and control the top dead point and the speed change point. The repeated positioning accuracy of the machine is within ±0.01mm. The slider stroke (Y1, Y2) can make the slider moderately inclined to meet the special needs of users.

4. High-precision guiding system, position measuring system and hydraulic balance function can meet the needs of full-length or eccentric machining.

5. The machine is equipped with a high-precision worktable deflection compensation mechanism to compensate for the deflection generated during work and ensure the bending angle accuracy of each point of the workpiece.

6. The surface of the cylinder plunger is plated with hard chromium, and the cylinder plunger has good self-lubrication, which can greatly improve the service life.

7. The oil cylinder processing adopts the whole forging-rough machining-finish machining-inner wall grinding-inner wall rolling process, so that the inner wall of the oil cylinder has both hardness and wear resistance and high cylindricity precision.

8, with, with motorized side discharge device. (Optional)

9, with a movable foot switch, easy to operate, with emergency power function.

10. The hydraulic control system is imported from BoschRexroth, Germany, and the cylinder seals are imported from Japan NOK or SKF seals.

11. The computer adopts the DA52S system of the Dutch DELEM company, which has complete functions, such as programming, inching, pressure keeping, slow recovery control, etc.

12. The machine tool can work continuously under rated load, while the hydraulic system has no leakage and the work is stable and stable.

13. The hydraulic system has overload overflow safety protection and filter screen blockage alarm display. Our company's hydraulic system oil tank, the use of low heat dissipation good design, to ensure that the oil temperature operation in the appropriate range.

Third, the machine processing capacity: the general cone, octagonal, hexagonal street lamp pole, high pole light pole, power pole
