The CNC hydraulic bending machine refers to a dual cylinder upward moving CNC hydraulic bending machine, which drives the extension and return of the left and right oil cylinders through various valve actions on the servo proportional valve, thereby driving the up and down of the slider.

The synchronization of the slider adopts fully closed-loop electro-hydraulic servo control technology. The position signal of the slider is fed back to the CNC system by the grating rulers on both sides, and then the CNC system controls the opening size of the synchronization valve to automatically adjust the amount of oil entering the cylinder, thereby controlling the synchronous operation of the slider (Y1, Y2) axis and always maintaining a parallel state to the worktable.

Structural characteristics of CNC hydraulic bending machine:

(1) Hydraulic transmission, the oil cylinders at both ends of the machine tool are placed on the slider, directly driving the sliding work.

(2) Adopting a mechanical block structure, stable and reliable.

(3) Quick adjustment of slider travel, manual fine-tuning, counter display.

(4) Adopting a fully welded steel structure, it has sufficient strength and rigidity.

(5) The slider synchronization mechanism adopts torsion axis forced synchronization.

(6) A wedge type deflection compensation mechanism is used to ensure high bending accuracy.

Instructions for using CNC hydraulic bending machine;

1. Firstly, connect the power supply, turn on the key switch on the control panel, and then press the oil pump start button. This way, you will hear the sound of the oil pump turning. (At this time, the machine is not moving)

2. Travel adjustment: When using a bending machine, attention must be paid to adjusting the travel, and a test drive must be conducted before bending. When the upper mold of the bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and machine. The adjustment of the itinerary also includes electric quick adjustment and manual fine adjustment.

3. When selecting a bending groove, it is generally necessary to choose a groove with a width 8 times the thickness of the board. If bending a 4mm sheet metal, a slot of about 32 should be selected.

4. Rear gear adjustment generally includes electric quick adjustment and manual fine adjustment, using the same method as a shearing machine.

5. Press the foot switch to start bending. Unlike the shearing machine, the bending machine can be released at any time. Once the foot is released, the bending machine stops and continues to move downwards.
