The unilateral wire loosening elimination method of cutting the wire electrodes through the reciprocating wire moving electrical discharge wires is characterized in that a frequency conversion device is used for controlling forward and reverse rotation speed of a wire storage cylinder, forward and reverse rotation differential rotation of the wire storage cylinder is achieved, tensile difference of forward and reverse moving wire electrodes of the wire electrodes cut by high-speed reciprocating wire moving electrical discharge wires is eliminated, the phenomenon of 'unilateral wire loosening' is eliminated, and therefore machining accuracy and surface roughness are improved, and service life of the wire electrodes is prolonged. The unilateral wire loosening elimination method of cutting the wire electrodes through the reciprocating wire moving electrical discharge wires has the advantages of being easy in implementation method, simple in structure, and strong in practicability.

Description

technical field [0001] The invention relates to a wire electric discharge processing technology, in particular to a high-speed reciprocating wire electric discharge wire cutting processing technology, in particular to a method for eliminating unilateral loose wires in a reciprocating wire electric discharge wire cutting processing electrode wire. Background technique [0002] At present, the electrode wire of the high-speed reciprocating wire EDM machine tool is driven by the wire storage cylinder for forward and reverse wire movement. Under normal circumstances, after a period of processing, the wire electrode will gradually loosen at one end of the wire storage cylinder. The phenomenon that one end is tight is commonly known as the phenomenon of "unilateral loose wire". Due to the rigidity of the electrode wire, it actually appears as follows after passing through the positioning guide wheel figure 1 The arc shape shown has a deviation δ from the common tangent line o...
