Technical Field

[0001] The invention relates to the technical field of wire cutting machine tools, and in particular to a high-stability automatic wire threading detection mechanism. Background Art

[0002] The wire cutting machine was developed when the phenomenon and causes of spark discharge corrosion damage to switch contacts were studied. It was found that the instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and corrode, thus creating and inventing the electric spark machining method.

[0003] When using the traditional automatic wire-threading detection mechanism for wire-cutting machines, the electrode wire is usually used to lift the metal sheet, and then the electrical signal is detected to determine whether the electrode wire is successfully threaded. In actual use, the electrode wire will inevitably be accompanied by a water film of coolant, which will easily isolate the signal and cause detection failure, affecting the stability of the automatic wire-threading detection mechanism. Therefore, a high-stability automatic wire-threading detection mechanism is proposed. Summary of the invention
