1. Hydraulic Oil
Check the oil level in the reservoir weekly, and after maintenance, the oil level should be filled up to the bottom of the oil window. Use ISO HM46 or MOBIL DTE25 hydraulic oil for the machine.
For a new machine, the oil should be changed after 2000 hours of operation, and then every 4000 to 6000 hours thereafter. The hydraulic oil should be replaced every time the oil is changed, and the reservoir should be cleaned.
The oil temperature should be around 35°C to 60°C and should not exceed approximately 70°C. Excessive temperature can lead to degradation of the oil quality and components.
2. Filtration
When changing the oil, the oil filter should be replaced or thoroughly cleaned each time.
If there are alarms related to the machine or if the oil filter is dirty, along with any other abnormalities, it should be replaced promptly.
The air filter in the reservoir should be checked and cleaned every three months, and it is recommended to replace it annually.
3. Hydraulic Components
Clean the hydraulic components (base materials, valves, motors, pumps, pipelines, etc.) monthly to prevent dust from entering the system. Do not use cleaning agents.
After a few months of using the new machine, check the pipe bends with or without fittings. If any abnormalities are found, they should be replaced promptly. After two months, all fasteners should be tightened, and this work should be carried out with the machine closed and without pressure.
Hydraulic System Plate Bending Machine - Structure and Features:
1. The machine has a fully welded steel structure, providing sufficient strength and rigidity.
2. Hydraulic transmission is used, with cylinders placed on both ends of the sliding worktable for direct driving.
3. The synchronization mechanism of the slide adopts a torque shaft for forced synchronization.
4. The machine has a mechanical stopper structure, ensuring stability and reliability.
5. The stroke of the slide can be quickly adjusted, with manual fine-tuning and a counter display.
6. It is equipped with a wedge-type deflection compensation mechanism to ensure high bending accuracy.
Bending Machine Structure:
The bending machine consists of a hinged frame, a table, and a clamping plate. The table is placed on a support and forms a baseplate. The base is connected to the fixed plate, and the seat shell is placed on the base. Inside the coil and cover plate, the coil is placed in the recess of the shell, which is covered by a top cover. When the coil is energized through the wire, the gravity generated by the power supply causes the sheet metal sandwiched between the pressure plate and the baseplate. As a result of electromagnetic force, various workpiece requirements can be achieved, and the side walls of the workpiece can be processed.
Bending Machine Usage:
Let's briefly introduce the processing of Q235 sheet metal using a traditional hydraulic press brake:
1. First, turn on the power by flipping the key switch on the control panel and press the pump start button to hear the sound of the rotating pump. (At this point, the machine is not in operation)
2. Stroke adjustment: Before bending, the bending machine needs to have stroke adjustment and perform a test. The bending machine mold should be lowered to the bottom, ensuring a certain gap thickness. Otherwise, it may damage the machine. In addition, there is an electric stroke adjustment for quick adjustment and a manual adjustment for fine-tuning.
3. Selection of bending slot: Generally, the slot width should be about 8 times the thickness of the gap. For example, for bending a 4mm sheet, a slot of around 32 should be selected.
4. Backgauge adjustment: Generally, there is a quick electric adjustment and a manual fine-tuning adjustment, similar to a shearing machine.
5. Press the foot pedal switch to start bending. Unlike a hydraulic shear, the foot can be released at any time. Releasing the foot will stop the machine from continuing its downward movement.
Maintenance and Care:
Before performing maintenance or cleaning the machine, the mold should be aligned to a lower position and wait until the work is completed. If starting or performing other operations, the mode selection should be set to manual, and safety should be ensured. The maintenance includes the following:
1. Hydraulic Oil:
Check the oil level in the tank weekly, and after maintenance, the oil level should be filled up to the bottom of the oil window. Use ISO HM46 or MOBIL DTE25 hydraulic oil for this machine.
For a new machine, the oil should be changed after 2000 hours of operation, and then every 4000 to 6000 hours thereafter. Every time the oil is changed, the reservoir should be cleaned.
The oil temperature should be around 35°C to 60°C and should not exceed approximately 70°C. Excessive temperature can lead to degradation of the oil quality and components.
2. Filtration:

3. Hydraulic Components:
Clean the hydraulic components (base materials, valves, motors, pumps, pipelines, etc.) monthly to prevent dust from entering the system. Do not use cleaning agents.
After a few months of using the new machine, check the pipes with or without bends. If any abnormalities are found, they should be replaced promptly. After two months, all fasteners should be tightened. This work should be carried out with the system closed and without pressure.
