Description

Technical field: [0001] The servo motor-driven numerical control sheet metal bending machine of the present invention belongs to the field of digitally controlled machine tools. Background technique: [0002] According to the driving mode of the slider, the sheet metal bending machine can be divided into mechanical bending machine and hydraulic bending machine. [0003] The mechanical bending machine uses a three-phase asynchronous motor as the driving power of the slider, and uses the clutch to change the speed, that is, the speed is changed according to the following process requirements: the slider starts to move down quickly, that is, it runs at high speed. When the bending operation is performed, the slider moves down slowly. When the slider returns, it runs at high speed. The disadvantage of this structure is that it has poor flexibility, and it is difficult to realize automation and digital control operation. Therefore, it is difficult to adapt to the current producti...

[0003] The mechanical bending machine uses a three-phase asynchronous motor as the driving power of the slider, and uses the clutch to change the speed, that is, the speed is changed according to the following process requirements: the slider starts to move down quickly, that is, it runs at high speed. When the bending operation is performed, the slider moves down slowly. When the slider returns, it runs at high speed. The disadvantage of this structure is that it has poor flexibility, and it is difficult to realize automation and digital control operations. Therefore, it is difficult to adapt to the current production requirements and has been eliminated in recent decades.

[0004] The hydraulic bending machine is the trend of development in recent decades. The slider moves in a straight line, and the oil cylinder is arranged on the wall panels on both sides. It is relatively easy to connect with the numerical control system. However, when loading and unloading, the oil pump is still working, so In terms of wasting energy, the hydraulic system of the machine tool may not leak oil temporarily, but in the long run, the machine tool will always leak oil

What's more, after the hydraulic system works for a certain period of time, oil needs to be changed, which will cause environmental pollution
