With the increasing demand for efficient, precise and environmentally friendly production in the manufacturing industry, the technology of bending machines has been constantly innovated. Pure electric bending machines and electro-hydraulic bending machines have become the two main mainstream technical directions in the market. Pure electric bending machines directly drive the ball screw or gear rack system with servo motors, relying entirely on electrical energy. Through the numerical control system, they can achieve high dynamic response, programmable setting of bending angle, speed and pressure parameters, with positioning accuracy reaching ±0.01mm, high repeatability positioning accuracy, only consuming electrical energy during the slider movement, standby power consumption is close to zero, comprehensive energy consumption is reduced by 40% - 60%, there is no risk of hydraulic oil leakage, the structure is simple, and daily maintenance only requires lubricating the guide rails and checking the electrical connections.
The electro-hydraulic bending machine combines a servo motor with a hydraulic system. It relies on both electrical energy and hydraulic oil for energy conversion. The hydraulic flow and pressure are adjusted through proportional valves or servo valves. Affected by changes in hydraulic oil temperature and valve response delay, the accuracy is typically ±0.1mm. Regular calibration is required. The hydraulic pump continuously operates to maintain system pressure, but the standby energy consumption is high. Long-term use may involve issues such as hydraulic oil replacement and pollution treatment. Regular replacement of hydraulic oil, filters, maintenance of valves and seals, and high maintenance costs are involved. However, it has a stability advantage in large-tonnage (such as over 2000 tons) bending. Pure electric bending machines are suitable for precision sheet metal processing, rapid changeover production, and clean workshops; electro-hydraulic bending machines are suitable for heavy industry processing, continuous high-intensity operations, and cost-sensitive scenarios. Currently, pure electric bending machines are developing towards higher tonnage and intelligentization. Electro-hydraulic bending machines can optimize energy efficiency through technology, and both have their own advantages and applicable boundaries. Enterprises can choose based on processing requirements, costs, and other factors.
