1. Hydraulic Oil System
a. Check the oil level in the tank every week. After hydraulic system maintenance, the oil level should also be checked. If the oil level is below the oil window, hydraulic oil should be added.
b. The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25.
c. The oil should be changed after the machine has been operating for 2000 hours, and subsequently every 4000 to 6000 hours of operation. Each time the oil is changed, the oil tank should be cleaned.
d. The oil temperature should be between 35°C and 60°C, and should not exceed 70°C. High temperatures can cause deterioration and damage to the oil and components.
2. Filters
a. The filters should be replaced or thoroughly cleaned every time the oil is changed.
b. If there are related alarms or the oil quality is not clean, the filters should be replaced.
c. The air filter on the oil tank should be inspected and cleaned every 3 months, and ideally replaced every year.
3. Hydraulic Components
a. Clean the hydraulic components (baseplate, valves, motors, pumps, oil pipes, etc.) every month to prevent dirt from entering the system. Do not use cleaning agents.
b. After one month of using a new machine, check for any deformations in the bends of the oil pipes. If there are abnormalities, they should be replaced. After two months of use, tighten all the connections of the components. This work should be done with the machine turned off and the system depressurized.
Hydraulic Plate Bending Machine
Structure and Features:
1. It adopts a fully welded steel structure, providing sufficient strength and rigidity.
2. Hydraulic transmission, with cylinders placed on both ends of the machine, directly driving the sliding work.
3. The synchronization mechanism of the sliding block adopts a torsion shaft for forced synchronization.
4. It uses a mechanical block structure, which is stable and reliable.
5. The sliding block stroke can be quickly adjusted and finely adjusted manually, with a counter for display.
6. It has a wedge-type deflection compensation mechanism to ensure high 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 pressure 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.
When in use, the coil is energized by connecting wires, which generates attractive force on the pressure plate, thereby clamping the sheet metal between the pressure plate and the base. Due to the electromagnetic clamping, the pressure plate can be made to meet various workpiece requirements and can process workpieces with side walls.
Operating Instructions for Bending Machine:
Here is a simple introduction to using a hydraulic bending machine for processing Q235 sheet metal:
1. First, turn on the power. Open the key switch on the control panel and then start the oil pump. You will hear the sound of the oil pump rotating. (At this time, the machine does not move.)
2. Stroke adjustment: It is essential to adjust the stroke carefully. Before bending, a trial run must be performed. When the upper mold of the bending machine reaches the bottom, there must be a gap of one sheet thickness. Otherwise, it may cause damage to the mold and the machine. Stroke adjustment can be done through electric rapid adjustment and manual adjustment.
3. Select the bending slot: Generally, a slot width that is 8 times the thickness of the sheet should be chosen. For example, if bending a 4mm sheet, a slot width of around 32 is required.
4. Adjust the back gauge: The back gauge usually has electric rapid adjustment and manual fine adjustment. The methods are the same as for shearing machines.
5. Step on the foot switch to start bending. Unlike shearing machines, you can release the foot switch at any time. Releasing the foot switch will stop the bending machine. Step on it again to continue downward movement.
Maintenance and Care of Bending Machine:
Before performing machine maintenance or cleaning, align the upper mold with the lower mold, lower it, and turn off the machine until the work is completed. If it is necessary to turn on the machine or perform other operations, set the mode selection to manual and ensure safety. The maintenance includes the following:
