A metal bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a worktable, and a clamping plate. The worktable is placed on the bracket, and the worktable consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge, and the base is composed of a seat shell, a coil, and a cover plate. The coil is placed in a 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 a wire, which generates an attractive force on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into various workpiece requirements, and can also process workpieces with side walls, making the operation very simple.

Working principle of metal bending machine:

The hydraulic bending machine includes a bracket, a worktable, and a clamping plate. The worktable is placed on the bracket, and the worktable consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base consists of a seat shell, a coil, and a cover plate. The coil is placed in a 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 a wire, which generates an attractive force on the pressure plate, thereby achieving the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into various workpiece requirements and can also process workpieces with side walls. The bending machine can meet the needs of various workpieces by replacing the bending machine mold.

Structural characteristics of metal bending machine:

1. Adopting a fully welded steel structure with sufficient strength and rigidity;

2. Hydraulic transmission, the oil cylinders at both ends of the machine tool are placed on the slider, directly driving the sliding work;

3. The slider synchronization mechanism adopts torsion axis forced synchronization;

4. Adopting a mechanical block structure, stable and reliable;

5. Quick adjustment of slider travel, manual fine-tuning, counter display;

6. A wedge type deflection compensation mechanism is used to ensure high bending accuracy.

Maintenance and upkeep of metal bending machine:

Before performing machine maintenance or cleaning, the upper mold should be aligned with the lower mold and the machine should be lowered and turned off until the work is completed. If startup or other operations are required, the mode should be selected as manual and ensured. The maintenance content is as follows:

1. Hydraulic oil circuit

1) Check the oil level in the fuel tank every week, and also check it after hydraulic system maintenance. If the oil level is below the oil window, add hydraulic oil;

2) The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25;

3) The new machine should have its oil changed after 2000 hours of operation, and every 4000-6000 hours of operation thereafter. After each oil change, the oil tank should be cleaned;

4) The system oil temperature should be between 35 ℃ and 60 ℃, and should not exceed 70 ℃. If it is too high, it may cause deterioration and damage to the oil quality and accessories.

2. Filter

1) The filter should be replaced or thoroughly cleaned every time the oil is changed;

2) If the machine tool has related alarms or other filter abnormalities such as poor oil quality, it should be replaced;

3) The air filter on the fuel tank should be inspected and cleaned every 3 months and replaced every 1 year.

3. Hydraulic components

1) Clean hydraulic components (substrates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system and avoid using cleaning agents;

2) After using the new machine for one month, check if there is any deformation at the bends of each oil pipe. If there is any abnormality, it should be replaced. After using it for two months, tighten all the connections of the accessories. When doing this work, the machine should be turned off and the system should be free of pressure.
