The working principle of an electro-hydraulic servo synchronous bending machine can be further subdivided into the following steps:

Upper and lower mold centering: During the bending process, the upper mold moves downward under the control of the electro-hydraulic servo system to align with the lower mold. This process is precisely controlled by a displacement sensor and pressure sensor in the electro-hydraulic servo system. The displacement sensor can monitor the position of the upper mold in real time, while the pressure sensor can monitor the pressure applied by the upper mold on the metal sheet. Through precise control of these two parameters, the upper and lower molds can be centered and ensure uniform pressure on the metal sheet during bending.

Side pressure device extension: After centering, the side pressure device extends to flatten the sheet metal against the mold surface. The side pressure device is typically composed of multiple hydraulic cylinders that can control the pressure and extension angle in each region separately. The numerical control system adjusts the pressure and motion speed of each cylinder through the electro-hydraulic servo valve according to the preset bending shape and parameters, ensuring uniform pressure on the metal sheet in all directions.

Bending process: After the metal sheet is clamped and flattened, the upper and lower molds begin to move downward according to the preset bending shape and parameters. During this process, the electro-hydraulic servo system precisely controls the pressure and motion of the hydraulic cylinder based on the instructions from the numerical control system, ensuring that the bending angle and shape are consistent with the presets. At the same time, the numerical control system also monitors various parameters during the bending process, such as the pressure of the hydraulic cylinder and the position of the upper and lower molds, allowing for timely adjustments in the event of any abnormalities.

Release and extraction: After the bending process is completed, the side pressure device relaxes its pressure first, then lifts the mold to remove the bent metal sheet from the machine. This process is also precisely controlled by the electro-hydraulic servo system and numerical control system. After release, the metal sheet can be extracted from the machine by a conveying device, while the mold can return to its initial position to await the next bending process.

The numerical control system plays a crucial role throughout the entire bending process. It not only controls the movement trajectory and bending force of each component according to preset bending shapes and parameters but also monitors various parameters during processing, such as the position of the upper and lower molds and the bending angle of the metal sheet. Through these monitoring data, the numerical control system can assess processing quality and safety, and issue alerts and processing instructions in the event of any abnormalities to ensure production efficiency and processing quality.

The main components of an electro-hydraulic servo synchronous digital control bending machine include the following:

Host machine: The host machine consists of a frame, a workbench, upper and lower mold devices, and side pressure devices. The frame and workbench are typically made of high-strength steel to support the entire device and withstand the high-intensity pressure during bending. The upper and lower mold devices are dies used for bending the metal sheet, and their shapes and sizes are customized according to needs. The side pressure devices are used to flatten the metal sheet against the mold surface and can also correct centering.

Electro-hydraulic servo system: This system includes an electro-hydraulic servo valve, hydraulic cylinder, and pressure sensor. The electro-hydraulic servo valve is the core of the system, which receives instructions from the numerical control system and translates them into hydraulic cylinder motion and pressure control. The hydraulic cylinder acts as an actuator, converting the output of the electro-hydraulic servo valve into actual motion and pressure. The pressure sensor monitors the pressure in the hydraulic cylinder and feeds back the pressure signal to the numerical control system to achieve precise pressure control.

Numerical control system: The numerical control system controls the motion of various components of the machine throughout the bending process, including the lowering of the upper mold, the raising of the lower mold, the extension and relaxation of the side pressure devices, etc. It receives input parameters from the operator and calculates the motion trajectory and bending force of each component based on preset bending shapes and parameters. Then, it sends these instructions to the electro-hydraulic servo system and other control systems to achieve precise bending processing.
 
Conveying device: Conveying devices include conveying belts, chains, etc., which are used to transport the metal sheet into the machine for processing and remove it from the machine after bending is completed. The speed and position of these conveying devices are precisely controlled by the numerical control system to ensure that the metal sheet is located in the correct position at the correct time for bending.

Safety cover: The safety cover is used to protect operators from hazards that may arise during the bending process. It includes a transparent glass window that allows operators to observe the bending process while preventing accidental harm.
