How to improve the hydraulic system of CNC PRESS BRAKE to improve stability and energy saving performance?

Improving the hydraulic system of CNC Press Brake to improve stability and energy-saving performance requires starting from hydraulic design, control technology, energy recovery and other aspects.

Selecting low-noise, high-efficiency hydraulic pumps (such as internal gear pumps or axial piston pumps) can effectively reduce pressure fluctuations and improve stability. Use proportional servo valves or electro-hydraulic proportional valves to achieve more precise pressure and flow control to avoid machining errors of workpieces due to hydraulic fluctuations. Use high-quality seals to reduce the risk of leakage and ensure the stability of the hydraulic system under high temperature and high pressure for long-term operation.

Through the feedback of pressure sensors and displacement sensors, a closed-loop control system is constructed to enable the hydraulic system to adjust the output in real time and maintain high-precision control performance. Add shock absorbers and buffers to the hydraulic circuit to reduce impact pressure and prevent the system from generating vibration or noise.

Selecting hydraulic oil with excellent antioxidant and wear resistance can extend the service life of hydraulic components. Install high-efficiency filters in the hydraulic system to remove impurities in time to prevent pollution from causing component wear or jamming.

Combined with servo motor and variable pump, hydraulic flow and pressure can be dynamically adjusted according to actual needs, and energy can be output only when needed, thus greatly reducing energy consumption. Servo drive technology can realize on-demand oil supply and reduce energy waste in standby state.

During the descending stage of the bending machine slider, the excess hydraulic energy is converted into electrical energy for storage or reuse by installing a hydraulic energy recovery unit. When the hydraulic cylinder stops moving, the high-pressure oil in the system is returned to the oil reservoir and reused to avoid energy loss.

A high-pressure and low-pressure dual pump combination is adopted, the high-pressure pump is used to provide pressure during bending, and the low-pressure pump is used to supplement the flow during the non-working stage, thereby saving energy. Logic valves are used instead of traditional valves to simplify the hydraulic circuit while reducing energy consumption and improving operating efficiency.

Intelligent algorithms are used to adjust the hydraulic output in real time according to different bending loads and working conditions to ensure optimal operating efficiency. The pressure and flow requirements of the hydraulic system at work are predicted by machine learning technology, and the control strategy is optimized in advance.

In the multi-cylinder structure, the synchronous movement of multiple hydraulic cylinders is achieved through the hydraulic servo system, which reduces energy loss and improves bending accuracy. Dynamically monitor and adjust the pressure on the left and right sides of the slider to prevent offset or error caused by uneven load.

Install an efficient cooler in the hydraulic system to avoid system performance degradation or component damage caused by excessive oil temperature. Ensure that the hydraulic oil is kept within the appropriate temperature range through an external cooling fan or liquid cooling device.

The modular design makes it easy to disassemble and replace each component, shortening the maintenance time. Configure a hydraulic monitoring system to monitor key parameters such as oil temperature, pressure, and flow in real time. Once the set value is exceeded, an alarm will be issued immediately or protective measures will be taken.

Use biodegradable hydraulic oil to reduce the impact on the environment and reduce the environmental risks caused by hydraulic oil leakage. Install a noise reduction cover or use a low-noise pump on the hydraulic pump and hydraulic motor to improve the operating environment and meet environmental standards.

By optimizing hydraulic components, adopting servo drive technology, designing an energy recovery system, and improving heat dissipation and maintenance methods, the stability and energy-saving performance of the CNC Press Brake hydraulic system can be significantly improved. This not only meets the needs of modern industry for high efficiency and high precision, but also conforms to the trend of sustainable development and has broad application prospects.
