With the increasing development of technology, modern sheet metal processing, especially the bending processing technology, has higher and higher requirements, and has different technical requirements for equipment and processing efficiency. There are strict control, so compared with hydraulic press brakes, the press brakes controlled by pure electric servo system are more and more accepted by major manufacturers.

Full-electric Servo Press Brake

Today we will briefly introduce the advantages of pure electric servo press brakes compared to hydraulic press brakes: In recent years, the maturity and cost reduction of high-power, high-torque servo motors and drive technologies have made relevant electric servo drive devices more and more are being applied. The CNC bending machine in the sheet metal industry has opened a new trend of pure electric servo-based drive instead of hydraulic drive. Next, we will compare the parameters of energy saving, environmental protection, processing efficiency, bending accuracy and maintenance cost. The advantages of electric servo bending machine compared to hydraulic bending machine.

Full-electric Servo Press Brake

1. One of the advantages of energy-saving pure electric servo drive technology is that the input power of the motor is proportional to the size of the load power, the power consumption is large when bending, the power consumption is small when the slider goes up without load, and basically no power consumption when the slider stops . However, the main motor and hydraulic pump of the hydraulic servo bending machine continue to run even if the slider does not work, consuming electricity. In addition, the mechanical main transmission efficiency of pure electric servo bending machine is more than 95%, the hydraulic transmission efficiency of hydraulic servo bending machine is below 80%, and the efficiency of hydraulic system components is lower after aging and wear.

2. The environmentally friendly pure electric servo bending machine does not use hydraulic oil, and there is no trouble in replacing hydraulic oil and hydraulic components, and there is no hydraulic oil leakage during the replacement, replacement process and the daily system of the system, and there is no waste oil treatment and pollution.

3. The slider speed is fast and the production efficiency is high.

Taking Zhihang flexible intelligent CNC bending center as an example, the gas is not limited by the column distance and throat depth of the C-shaped frame design, and can be processed by a bending machine, which is more flexible and convenient. And its servo-type design allows the machine to start and stop quickly, so the processing speed is fast and the processing time can be shortened.

4. High bending accuracy.

The bending speed of the pure electric servo bending machine can be adjusted. It can be bent according to different thicknesses, different materials and different bending lengths, and a more suitable bending speed can be set to improve the bending accuracy and maintain high productivity. The deflection compensation shaft of the pure electric servo bending machine adopts the VILA structure compensation device, and the bending accuracy is higher.

The bending angle error of the hydraulic bending machine is within ±1°, and the main drive of the servo bending machine is driven by the servo motor to drive the screw, and the transmission accuracy is higher. It is good to ensure that the bending angle error is within ±0.5°.

5. Low maintenance cost.

The hydraulic oil of the hydraulic bending machine needs to be replaced regularly; pumps, valves and seals are prone to failure and damage, and the hydraulic system is prone to pollution, and it is difficult to find and eliminate faults. Once the hydraulic system is polluted, it will be difficult to clean the system, and will cause environmental pollution. The drive system of the pure electric servo bending machine is simple, there is basically no maintenance cost, and only regular lubrication is required.
