Bending Machine

1. First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so that you can hear the sound of the oil pump turning. (The machine does not move at this time)

2. Stroke adjustment. When using the bending machine, you must pay attention to adjusting the stroke. Be sure to test the machine before bending. When the upper die of the bending machine moves down to the bottom, there must be a gap of the plate thickness. Otherwise, it will cause damage to the mold and the machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.

3. Bending notch selection, generally choose a notch 8 times the width of the plate thickness. If you bend a 4mm sheet, you need to choose a notch of about 32.

4. The rear stop adjustment generally has electric quick adjustment and manual fine adjustment, and the method is the same as the shearing machine.

5. Press the foot switch to start bending. The bending machine is different from the shearing machine. It can be released at any time. The bending machine stops when the foot is released, and it continues to move down.

1. Hydraulic oil circuit

a. Check the oil level in the oil tank every week. If the hydraulic system is repaired, it should also be checked. If the oil level is lower than the oil window, add hydraulic oil;

b. The hydraulic oil used is ISO HM46 or MOBIL DTE25;

c. The oil should be changed after 2000 hours of work for a new machine, and after every 4000-6000 hours of work. The oil tank should be cleaned every time the oil is changed;

d. The system oil temperature should be between 35℃ and 60℃, and should not exceed 70℃. If it is too high, it will cause the oil and accessories to deteriorate and be damaged.

2. Filter

a. The filter should be replaced or thoroughly cleaned every time the oil is changed;

b. If the machine tool has related alarms or other filters such as unclean oil quality, they should be replaced;

c. The air filter on the oil tank should be checked and cleaned every 3 months, and it is best to replace it once a year.

3. Hydraulic components

a. Clean hydraulic components (base plate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system. Do not use detergents;

b. After using a new machine for one month, check whether the bends of the oil pipes are deformed. If there are any abnormalities, they should be replaced. After two months of use, tighten the joints of all accessories. When doing this work, the machine should be turned off and the system should be pressure-free.
