High-speed punched hole tubular shape electrode

Abstract

The invention relates to a tubular electrode with high speed perforated pores, which comprises an outer tube of which the inside is provided with an inner core axially. Further, the inner core and the outer tube are fixed into an integral structure by stretching. Further, the inner core runs through the circle center of the outer tube. Further, the inner core is a rectangular structure which runs through the diameter of the outer tube. Further, the inner core is an integral structure consisting of three fan-shaped tubes with the same semi-diameter, and the semi-diameter of the fan-shaped tube is half of the internal diameter of the outer tube. As a preferred mode, the fan angle of each of the three fan-shaped tubes is 120 degrees, thus not only the processing speed can be improved, but also the electrical conductivity of the outer tube electrode in use can be improved. The tubular electrode is provided with the inner core to not only effectively remove the middle part of the processing pore of the work piece, but also reduce the consumption of the electrode when the electrode is used and consumed. The tubular electrode has the advantages of fast processing speed, good surface smooth finish, high straightness, small ellipticity, good mechanical property and the like.

Description

technical field [0001] The invention relates to a perforated electrode, more specifically a high-speed perforated tubular electrode applied to numerical control mechanical equipment of electric discharge equipment. Background technique [0002] Among the special processing methods, EDM is a more commonly used processing method. It is suitable for processing difficult-to-cut materials such as cemented carbide and hardened steel, as well as other complex shapes or special parts. It is mainly used for processing conductive materials such as metals, and its application fields are also expanding. [0003] As one of the EDM methods, the EDM high-speed small hole machining process has the following processing principles: figure 1 As shown, the tubular electrode 2 is energized and then rotates and feeds into the workpiece 4 along the axis. Among them, the tubular electrode 2 is fed with a high-pressure working fluid 1, which is used to remove corrosion and has a cooling effect on ...

AI Technical Summary

Problems solved by technology

Since the tubular electrode 2 is a hollow tubular structure, it consumes a lot, which increases the processing cost

In addition, due to the tubular structure, it is easy to be shaped like figure 2 The tapered protrusions shown are prone to this machining problem, especially when machining larger diameter holes in the workpiece 4
