The CNC hydraulic sheet metal bending machine includes a bracket, a worktable, and a clamping plate. The worktable is placed on the bracket and consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a seat shell, a coil, and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, which generates an attractive force on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into various workpiece requirements and can also process workpieces with side walls.

Structure and characteristics of CNC hydraulic sheet metal bending machine:

1. Adopting a fully welded steel structure with sufficient strength and rigidity.

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

3. The slider synchronization mechanism adopts torsion axis forced synchronization.

4. Adopting a mechanical block structure, stable and reliable.

5. Quick adjustment of slider travel, manual fine-tuning, and counter display.

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

Usage of CNC hydraulic sheet metal bending machine:

A brief introduction to the processing of Q235 sheet metal using a regular 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 should be paid to adjusting the travel, and a test drive should 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.

Debugging and operation of CNC hydraulic sheet metal bending machine:

1. After the hydraulic bending machine is installed and leveled, first wipe off the rust proof oil at each sliding and processing surface of the hydraulic bending machine, and carefully clean it. According to the equipment lubrication diagram, refill the appropriate lubricating oil at each sliding point as required.

2. Check the firm bolts at each connection to prevent loosening caused by transportation and lifting from affecting the use of the hydraulic bending machine.

3. Clean the fuel tank, check the filter screen, and add sufficient hydraulic oil as required. According to the instructions, add hydraulic oil to the return oil of the oil pump.

4. Check the electrical components, connect the power supply after confirming that there are no hidden dangers, start the motor, confirm that the oil pump is turning correctly, and then perform an idle run for three minutes.

5. Select the electrical button to the jog position, step on the foot switch, and allow the hydraulic bending machine to travel up and down several times without load to check if all electrical and hydraulic components are working properly.

6. Trial folding plate: Select a reasonable lower die V-groove and hydraulic bending machine pressure based on the thickness and length of the plate. The trial folding plate should be thin first and then thick, and the pressure should be small first and then large, in order to check the execution of commands by various components.
