Problems solved by technology

[0002] Whether the tension of the electrode wire of the wire cutting machine meets the requirements is closely related to the processing quality; the existing device and method for detecting and adjusting the tension of the electrode wire usually adopts a set on the electrode wire outside the processing section between the upper head and the lower head. The tension detection wheel judges the tension value of the electrode wire at the processing section by the measured tension value, and then adjusts the tension by changing the position of the tension wheel; but because the electrode wire passes through the reversing wheel and the guide wheel, the There is friction in the middle, and there is a certain difference between the measured tension value and the tension value of the electrode wire at the processing section. When the electrode wire reciprocates, the tension value detected by the sensor can only reflect the tension of one side of the electrode wire. , and the processing quality is determined by the tension value of the wire electrode in the processing section, but the tension detection wheel cannot be installed at the processing section, so this method is not accurate enough for the detection and control of the wire tension in the processing section, which affects the processing quality
