Light pole equipment -CNC Tandem Press Brake Machine

Main performance and features:

1. The frame is composed of fuel tank, pallet, bracket, workbench, left and right wall panels and sliders to ensure the structural strength of the frame. The vibration stress relief method is adopted and the surface sand blasting is used to remove rust.

2, the principle of machine synchronization: the application of electro-hydraulic servo proportional valve to ensure dual synchronization, the use of BoschRexroth company's electro-hydraulic proportional valve, its performance is characterized by high operating force continuous action electromagnet, mechanical motion pair in the friction is minimal and has fast working characteristics of precision electronic amplifier.

Each end of the table motherboard is equipped with a grating ruler, which continuously reflects the slider stroke position and synchronization error, and sends the two difference values into the CNC control system to control the electro-hydraulic proportional valve, so that each single two-cylinder synchronization. Since the grating ruler is not directly installed on the frame wall panel, but is installed on the C-frame fixed on the workbench motherboard, and takes the workbench as its reference point, the deformation of the slide itself and the frame under load will not affect the measurement and control accuracy of the grating ruler. In the case of dual-machine synchronization, the differential potentiometer installed between the two slides transforms the mechanical synchronization information into an electrical signal and transmits it to the synchronization board and the control system. Through the BoschRexroth amplifying board, the electro-hydraulic proportional valve is controlled to make the dual-machine synchronous action.

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

4, high-precision guidance system, position measurement system and hydraulic balancing function can meet the needs of full-length or eccentric machining.

5, the machine is equipped with a high-precision table deflection compensation mechanism, controlled by the numerical control system (V axis) to compensate for the deflection generated during work to ensure the workpiece processing accuracy.

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

7, cylinder processing using the whole forging - roughing - finishing - inner wall grinding - inner wall rolling process, so that the inner wall of the cylinder both hardness and wear, but also has a high cylindricity accuracy.

8. The hydraulic control system is imported from BoschRexroth, Germany, and the cylinder seals are the world's top grade NOK or SKIF seals from Japan.

9, the computer uses the DA52 system of DELEM company in the Netherlands, which is fully functional, with programming, point, pressure holding, slow rebound control and other functions.

10, the machine can work continuously under the rated load, and the hydraulic system has no leakage and continues to work stable and good performance.

11, the hydraulic system has overload overflow safety protection and filter blocking alarm display.
