Description

Technical field: [0001] The invention relates to the technical field of numerical control wire electric discharge cutting machine, in particular to a wire nozzle device of numerical control electric discharge wire cutting machine. Background technique: [0002] Under the new situation of the rapid development of my country's industrial technology, it is urgent to vigorously develop processing technologies such as various molds, electrodes and precision parts, and CNC wire cutting technology is exactly in the field of processing technologies such as various molds, electrodes and precision parts. a key technology. At present, in the research and development process of new products in the TV, instrument and other industries, CNC WEDM is often used to directly cut parts, which greatly shortens the development cycle, reduces costs, and improves product precision and quality. Therefore, the research and improvement of EDM machine tools are the needs of my country's domestic market...

AI Technical Summary

Problems solved by technology

[0003] Although CNC wire-cutting machine tools have been widely used in my country, there are still some shortcomings in the existing CNC wire-cutting machine tools. The existing CNC wire-cutting machine tools are used to guide the upper and lower arms of molybdenum wire. The end is only equipped with a guide wheel for guiding the molybdenum wire and a water-guiding mechanism for the molybdenum wire, resulting in a long distance between the conductive block and the cutting molybdenum wire, and low efficiency; the water-guiding mechanism has only one water injection hole, and the molybdenum wire Molybdenum wire is more likely to break if the wire is not filled with enough water; the service life of the conductive block is low, and once the wire groove on the conductive block is worn out, it must be replaced directly, which will waste resources or seriously affect the quality and accuracy of the processed product; When the wire is running, because the upper and lower ends are directly guided by the guide wheel, the molybdenum wire shakes a lot, which also affects the processing quality; the traditional CNC WEDM machine tool is very inconvenient to replace the molybdenum wire and thread the wire, and wastes a lot of time
