Abstract

The invention relates to a wire cutting machining method and device for maintaining the constant tension of a molybdenum wire in the process of machining. The machining method comprises the followingsteps: in the process of machining, performing real-time detection on the tension condition of the molybdenum wire by a tension detection module, and when the tension condition exceeds the tension setby a tension adjusting module, controlling a high-frequency pulsed power supply to be turned off by the tension adjusting module, and stopping machining a workpiece; controlling the rotating speed ofthe wire storage cylinder to be reduced by the tension adjusting device, and conveying the wire at a low speed to adjust the tension of the molybdenum wire, so that the tension of the molybdenum wirereturns to the set tension; controlling the high-frequency pulsed power supply to be turned on by the tension adjusting device, and machining the workpiece again; and repeating the steps until completing the worpiece machining. The method and the device have the characteristics of being high in sensitivity, high in stability, simple in structure and the like, can solve the problem of adjustment lagging in a traditional tension adjusting mechanism, ensure that the tension of the molybdenum wire is kept constant in wire cutting machining, and realize constant tension machining.

Description

technical field [0001] The invention relates to the field of electric discharge wire cutting processing, in particular to a wire cutting processing method and device for maintaining constant molybdenum wire tension during processing. Background technique [0002] The reciprocating wire cutting machine tool has the advantages of simple operation, low cost, and can process workpieces with large thickness and large taper. It is the main EDM equipment produced and used in my country. However, the machining accuracy of the reciprocating wire cutting machine tool is low, which seriously affects the further development of the reciprocating wire cutting machine tool. Among the many factors affecting the machining accuracy, the tension change of the electrode wire has a greater impact on the machining accuracy. In the reciprocating wire cutting machine tool, the electrode wire is always in a state of rapid reciprocating motion. With the progress of electric discharge machining, the ...
