Press brake is divided into torsion shaft press brake, electric hydraulic press brake two categories. At present, with the development trend of the market, pure electric press brake also occupies a place in the market, so what are the advantages of pure electric press brake?
First of all, the pure electric bending machine is different from the torsional shaft and electro-hydraulic series. It completely relies on electric energy to work. Compared with the other two, it does not need a huge oil tank and motor as well as a complex oil circuit system. Bending action is controlled by high precision servo motor. The slider of the general bending machine is controlled by the cylinder, and the sliding speed is limited. The servo motor is different, the speed can be set can be fast or slow, more efficient than ordinary bending machine. See Table 1 for comparison.
Table 1: hydraulic and pure electric slider speed comparison
Second is high precision, because the servo motor control, hydraulic bending machine bending Angle error within ±1°, and the main drive of the servo bending machine through the servo motor drive screw drive, transmission accuracy is higher, through a variety of plate bending Angle measurement, can well ensure that the bending Angle error within ±0.5°.
Of course, the above quality performance also increases the maintenance cost of pure electric bending machine. At the same time, relatively large pressure bending machine, servo motor power will be very large, the price will be very expensive. Therefore, pure electric bending machine is generally aimed at the thin plate with high dimensional accuracy. So in most cases, you will choose the electro-hydraulic bending machine.
