1. Hydraulic Oil System
a. Check the oil level in the tank weekly, and also after hydraulic system maintenance. If the oil level is below the sight glass, add hydraulic oil.
b. The recommended hydraulic oil for this machine is ISO HM46 or MOBIL DTE25.
c. Replace the oil after the machine has operated for 2000 hours, and subsequently every 4000 to 6000 hours of operation. Each time the oil is changed, clean the tank.
d. The oil temperature should be maintained between 35°C and 60°C and should not exceed 70°C. High temperatures can cause degradation of the oil and damage to components.
2. Filters
a. Replace or thoroughly clean the filters during each oil change.
b. If there are any related alarms or if the oil quality is poor, replace the filters.
c. Check and clean the air filter on the tank every 3 months, and ideally replace it once a year.
3. Hydraulic Components
a. Clean the hydraulic components (valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system. Do not use cleaning agents.
b. After one month of use, check the bending points of all oil pipes for any deformations. If any abnormalities are found, replace the pipes. After two months of use, tighten all connections of the components. Ensure that the machine is switched off and the system is depressurized when performing this task.
Hydraulic Plate Bending Machine
Structure and Features:
1. It adopts a fully welded steel structure, providing sufficient strength and rigidity.
2. Hydraulic transmission, with hydraulic cylinders placed on both ends of the machine, directly driving the sliding work.
3. The sliding synchronization mechanism adopts a torsion shaft for forced synchronization.
4. It uses a mechanical block structure, ensuring stability and reliability.
5. The sliding stroke can be quickly adjusted and finely adjusted manually, with a counter for display.
6. It features a wedge-type deflection compensation mechanism to ensure higher bending accuracy.
The bending machine includes a frame, a worktable, and a clamping plate. The worktable is placed on the frame and consists of a base and a pressing plate. The base is connected to the clamping plate through hinges. The base is composed 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.
During use, the coil is energized by the wire, generating electromagnetic force to clamp the sheet metal between the pressing plate and the base. The electromagnetic clamping allows for various workpiece requirements and enables the processing of workpieces with side walls.
Operating Instructions for the Bending Machine:
Here is a brief introduction to using the hydraulic bending machine for processing Q235 sheet metal:
1. First, connect the power supply and turn on the key switch on the control panel. Then, start the oil pump, and you will hear the sound of the pump rotating. (At this point, the machine is not in operation.)
2. Stroke adjustment: It is crucial to adjust the stroke when using the bending machine. Before bending, a test run must be performed. The lower mold of the bending machine must have a gap of one sheet thickness when it reaches the bottom. Otherwise, it may cause damage to the mold and the machine. Stroke adjustment can be done through electric rapid adjustment or manual adjustment.
3. Selection of bending groove: Generally, a groove width of approximately 8 times the thickness of the sheet should be selected. For example, for bending a 4mm sheet, a groove width of around 32 should be selected.
4. Adjustment of the back gauge: The back gauge usually has electric rapid adjustment and manual fine adjustment, similar to a shearing machine.
5. Step on the foot pedal switch to start the bending process. Unlike a shearing machine, the foot pedal can be released at any time. Releasing the foot pedal will stop the bending machine, and pressing it again will continue the downward movement.
Maintenance and Care of the Bending Machine:
Before performing machine maintenance or cleaning, align the upper mold with the lower mold and lower it, then turn off the machine until the work is completed. If any startup or other operations are required, set the mode selection to manual and ensure safety. The maintenance tasks are as follows:
