The wire 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. 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.

Structure description of wire bending machine:

1. Sliding block part: It adopts hydraulic transmission, and the sliding block part is composed of a sliding block, an oil cylinder, and a mechanical stopper fine adjustment structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) drives the slider to move up and down through hydraulic pressure. The mechanical stopper is controlled and adjusted by the numerical control system;

2. Workbench section: Operated by a button box, the motor drives the material rack to move forward and backward, and the distance of movement is controlled by the CNC system, with a small reading of 0.01 millimeters (both front and rear positions have travel switch limits);

3. Synchronization system: This machine is a mechanical synchronization mechanism composed of torsion shafts, swing arms, joint bearings, etc. It has a simple structure, stable and reliable performance, and high synchronization accuracy. The mechanical stopper is adjusted by a motor and controlled by a numerical control system;

4. Material blocking mechanism: The material blocking is driven by a motor, and the two screw rods are synchronously moved through chain operation. The CNC system controls the size of the material blocking.

Structural characteristics of wire 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 wire 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 safety should be 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.
