A large 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.

Large bending machine structure:

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 large bending machines:

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.
