I.

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 with worktable

The main performance and characteristics of electro-hydraulic synchronous CNC bending machine:

1. The frame is composed of an oil tank, a support block, a workbench, a left and right wallboard and a slider, which ensures the structural strength of the frame.

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 proportional directional valve, its performance characteristics are 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 electric appliance controls the synchronous action of the two machines.

3, DELEM CNC system can automatically calculate and adjust the bending force. And can automatically calculate and control the top dead point, speed change point.

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. The working platform is designed as an external packaging structure, which greatly increases the strength of the wings on both sides.

6. The surface of the cylinder piston 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 a movable foot switch, easy to operate, with emergency power function. Provide crush resistant cable.

9. Complete sets of hydraulic control system are imported from BoschRexroth (Dr. Rexroth) Company of Germany. All seals are made of imported materials, turning high precision seals, SKF or NOK type.

10. 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.

The stroke (Y1, Y2) of the sliding block can make the sliding block tilt in a certain range, which is convenient for manufacturing an 8-angle lamp pole and can control the opening of the big head and the small head to be consistent.

Our company specially designed long guide slider, slider accuracy is better, smooth operation, anti-bias load.

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

12. The hydraulic system has overload overflow safety protection and filter screen blockage alarm display. Our company's hydraulic system oil tank, using low heat dissipation good square tube design, heat dissipation area is twice as large as conventional design, to ensure that the oil temperature operation in the appropriate range.

13. Machining capacity: general cone, octagonal, hexagonal lamp pole, high pole lamp pole.

14. Our company in the street lamp pole mold above the R & D design and production, greatly improve the production efficiency and the quality of the street lamp pole, easy to operate, mold reliable, long service life.

15. Unique design of fast side discharge, safe, reliable, fast, reduce the intensity of the operator's work.

16. The special design of the street lamp pole special front support structure, easy to place the whole stack of plates, single plate left and right forward and backward movement, reduce the working intensity of the operator.
