How does a hydraulic press brake work?

1. First connect the power supply, turn on the switch on the control panel, and then start the oil pump.

　　Hydraulic press brake pre-start preparation:

　　(1) Regularly lubricate the moving parts with centralized oil supply, such as guide rails and backstops;

　　(2) Check the cleanliness and damage of the mold, and deal with any abnormalities found in time;

　　(3) Check the parallelism of the rear gear and the tension of the transmission belt.

　　Hydraulic press brake startup procedure tutorial:

　　(1) Operate the machine tool correctly according to the operating procedures;

　　(2) If any abnormality occurs during the machining operation, stop immediately for inspection, and refer to the relevant troubleshooting methods in the training manual for troubleshooting;

　　(3) When the machine tool stops during operation, it should be treated differently, and it cannot be blindly operated to avoid damaging the machine tool;

　　(4) For newly implemented processes, inspect the workpiece according to the drawings to avoid batch errors.

　　(5) When the mold is abnormal during bending, stop the machine and check immediately;

　　(6) Regularly check whether the actual position of the X-axis is consistent with the detected value. Adjust in time if there is any deviation.

　　2. Stroke adjustment. Pay attention to stroke adjustment during use, and perform detection before using CNC bending. When the upper mold descends to the bottom, ensure that there is a gap between the plate thicknesses. Otherwise, it will damage the mold machine. Stroke adjustment is also a kind of electric fast adjustment.

　　3. Select the arc notch, generally choose a notch 8 times the plate thickness. If the plate is bent 4 mm, you need to choose about 32 notches.

　　4. The rear stop is generally adjusted using the same electric fast adjustment and manual fine adjustment as the shearing machine.

　　5. The foot switch starts bending. The mold of the CNC flanging machine is different from the shearing machine. It can be released at any time. After releasing the foot, it stops, and after stepping down, it continues downward.

　　Safety technology and maintenance of hydraulic press brake:

　　1. Operators must be familiar with the structure and performance of the shearing machine. The shearing machine is operated by most people at the same time, and a special person must be in charge of production.

　　2. Avoid putting your hands into the upper and lower blades to avoid accidents.

　　3. Do not place all sundries and tools on the workbench to avoid being rolled into the blade and causing accidents.

　　4. Regularly check the sharpness of the blade. If the blade is found to be dull, it should be sharpened or replaced in time. Sharpening the blade only needs to sharpen the thickness of the blade.

　　5. Regularly check all parts of the hydraulic folding machine to keep the machine and surrounding areas clean and the cable insulation good.

　　6. The mesh oil filter installed at the oil pump suction port should be checked and cleaned frequently to maintain the oil level of the oil filter. If the oil filter is clogged and the oil level is reduced, the oil pump will be sucked empty, affecting the service life of the oil pump.

　　7. When the return cylinder pressure is low, the return cylinder can be inflated. The method is: protect the bottle cap and valve cover, install the inflation tool, connect the nitrogen cylinder to the other end of the inflation tool (oxygen-free), open the inflation tool, slowly open the nitrogen cylinder shut-off valve, pay attention to the inflation pressure gauge. 6.0mpa, immediately close the gas cylinder shut-off valve. Turn off the inflator, open the inflator, install the valve cover and protective cap.

　　8. Check the nitrogen pressure in the return cylinder every three months, and add it in time if it is lower than the specified pressure.
