Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting, and in particular relates to a wire cutting machine tool capable of supplying cooling liquid without dead angles. Background Art

[0002] Wire EDM (Wire Cut Electrical Discharge Machining), also known as wire cutting or wire EDM (Wire EDM), is a type of mechanical equipment commonly used in metal cutting. The following is a detailed description of wire EDM: Its basic operating principle is to use a continuously moving thin metal wire (called an electrode wire) as an electrode to erode metal and cut the workpiece using pulsed spark discharge. When the gap between the workpiece and the wire electrode is large enough for the pulsed voltage to penetrate, a spark discharge occurs between the two, cutting the workpiece. After the electrode wire is discharged, it is no longer used. A non-resistance, anti-electrolysis power supply is used, and wire EDM is generally equipped with automatic wire threading and a constant tension device.

[0003] The impact of cooling water supply dead corners includes heat accumulation: areas that cannot be fully covered by cooling water will cause heat to not be dissipated in time, causing the local temperature of the electrode wire and the workpiece to be too high. The high temperature environment will accelerate the wear of the electrode wire and reduce its service life. At the same time, high temperature will also affect the cutting quality and accuracy of the workpiece. Discharge channel blockage: Insufficient cooling water supply or dead corners will cause impurities and metal chips in the discharge channel to be unable to be removed in time. These impurities and metal chips will block the discharge channel, affecting the stability of the discharge and the cutting efficiency. In severe cases, it may even cause machine tool failure or damage. The quality of the cutting surface is reduced: due to heat accumulation and discharge channel blockage, cracks, burns or burrs may appear on the cutting surface. Utility Model Content
