Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting equipment, in particular to a wire threading and wire removing mechanism for wire cutting. Background Art

[0002] The electrospark machining method was originally invented because it was discovered that the instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and corrode. The wire cutting machine uses this principle, using a moving metal wire as a tool motor and passing a pulse current between the metal wire and the workpiece, using the corrosion effect of the pulse current discharge to cut the workpiece.

[0003] In the prior art, Chinese patent publication number CN218487394U discloses a multi-wire cutting device for a multi-wire cutting machine, which belongs to the field of mechanical processing technology. The multi-wire cutting machine includes a workbench, a cutting table, a cutting frame and a multi-wire cutting box. The cutting table is threadedly slidably connected to the workbench, the cutting frame is fixedly connected to the workbench, and the multi-wire cutting box is threadedly slidably connected to the cutting frame. A winding wheel, a movable frame and an electric telescopic rod are provided in the multi-wire cutting box, so that the multi-wire cutting machine can automatically and accurately adjust the cutting position of the workpiece during use, thereby effectively improving the working efficiency of the multi-wire cutting machine. At the same time, the overall structure of the multi-wire cutting box is simple and can provide efficient cutting force when in use. The cutting wire can also be positioned by a limiting wheel to prevent deviation during the cutting process, thereby effectively improving the practicality and cutting quality of the multi-wire cutting machine.

[0004] The metal wire used in the wire cutting process is mostly molybdenum wire. The two ends of the molybdenum wire are fixed on the machine head and the base, and the precise cutting of the workpiece is achieved through the movement of the molybdenum wire. However, it is not convenient to remove and thread the molybdenum wire, and the process of replacing the molybdenum wire is rather cumbersome, which reduces the cutting efficiency, so it needs to be improved.
