This machine has high labor productivity and high working accuracy for bending metal sheets. It uses upper and lower molds of different shapes to bend into various shapes of workpieces. The slider stroke can bend the sheet metal once, and after multiple bends, complex shaped workpieces can be obtained. When equipped with corresponding equipment, it can also be used for punching.

■ Product appearance structure
1. Through computer-aided optimization design, the appearance is beautiful.
2. The machine adopts a steel plate welding structure with sufficient strength and rigidity. The hydraulic transmission ensures that serious overload accidents will not occur due to changes in the thickness of the sheet metal or improper selection of the "V" groove in the lower mold during operation. In addition, this machine has the characteristics of stable operation, easy operation, low noise, safety and reliability.
3. There is a mechanical stopper in the oil cylinder to ensure the repeated positioning accuracy of the slider to the bottom dead center, in order to ensure the consistency of the bending angle during mass production.
4. Adopting overall tempering for internal stress elimination and CNC floor boring and milling machine frame processing ensures the installation surface accuracy of the oil cylinder, guide rail, and worktable.
5. Remove rust from the overall framework and spray anti rust paint.
■ Work slider structure
1. This machine adopts hydraulic and electrical control, and the slider stroke can be adjusted arbitrarily. It also has standard actions such as jogging, semi-automatic, and automatic. Adopting the jogging standard can facilitate mold testing and adjustment.
2. Upward bending machine design, dual oil cylinders working simultaneously, balanced, convenient, and safe operation
3. There is a pressure holding delay function at the bottom dead center to ensure the accuracy of the workpiece.
Under relevant national standards, the bending angle accuracy can reach ± 45 degrees. (Reference standard JB/T22572-2011)
5. It has a slow descent control function, allowing operators to better control the workpiece.
■ Hydraulic system
1. The hydraulic system can achieve fast and slow descent of the slider, bending of the working speed, fast return, and emergency stop of the slider during the upward and downward processes.
2. The oil pump adopts (SUNNY, USA) gear pump, which can withstand high pressure and low noise.
3. The oil pipeline adopts imported sealing rings, which have good sealing performance, reliable operation, long service life, and overcome oil leakage.
4. The machine tool can work continuously under rated load, with no leakage and continuous stability in the hydraulic system, and high accuracy.
■ Electrical control system
1. Electrical components and materials comply with international standards, are safe, reliable, have a long lifespan, and have strong anti-interference capabilities.
2. Comes with a movable foot switch operation.
3. Select high-quality branded products for electronic control components.
4. The machine tool adopts an AC 380V three-phase four wire power supply, and the control circuit is AC 220V voltage
5. The main circuit of the motor has short circuit, overload, and phase loss protection.
6. The operation buttons are installed on the button table of the machine tool, and the electrical switches and indicator lights are installed in a dedicated electrical control box.
7. The oil pump stop button also serves as the main button of the machine tool. When the oil pump stops working, the entire machine tool stops working.
8. The machine tool is equipped with corresponding jog control buttons and emergency stop buttons.

■ Sliding block synchronous control
The synchronization of the slider stroke in the bending machine adopts a mechanical hydraulic synchronization mechanism, which has a simple structure, stability and reliability, and has the required synchronization accuracy for this machine. It generally does not require frequent maintenance and can maintain long-term use.

■ Rear blocking material
1. The adjustment of the rear material is driven by an electric motor, and after deceleration, it is driven by a screw.
2. The rear stop material screw adopts precision screw positioning and high-precision guide rail support.
3. H-type synchronous belt synchronous wheel transmission has high transmission accuracy and low noise.
4. Equipped with adjustable gear finger holders that can be adjusted vertically and horizontally.

E21 system
