Due to the wide application of oil-electric hybrid CNC bending machine and further intensified market competition, for the use of bending machine manufacturers,
power consumption has become an important part of its production cost, so reducing the energy consumption of bending
machine has become an effective way to reduce costs and improve product competitiveness.
The servo oil-electric hybrid system uses two servo motors and servo pump to control the left and right cylinders.
The servo motor controls the output flow of the oil pump according to the program setting, and then controls the movement speed and position of the slider.
The whole process has no throttling phenomenon. Therefore, all the energy output by the oil pump is supplied to the left and right cylinders.
The distribution of oil is basically on demand, without throttling loss, which can realize the real sense of energy saving.
In addition, the application of servo motor greatly reduces the energy consumption of the system in the working gap. Excellent energy saving effect,
compared with the model, energy saving rate of 70%. For large tonnage, especially for heavy CNC bending machine, the advantage is more prominent,
that is to say, it only needs one-third of the oil.
