Embodiment Construction

[0043] Since the present invention discloses an electrode tip for a plasma cutting machine, and the relevant principles and implementation methods of the plasma cutting machine used in it are already understood by those skilled in the art, a complete description will not be given in the following description. At the same time, the drawings compared below are intended to express the meanings related to the features of the present invention, and are not and need not be completely drawn according to the actual size, which is stated in advance.

[0044] The electrode tip must have high conductivity, the higher the conductivity, the higher the operating efficiency. In addition to high electrical conductivity, the electrode tip for plasma cutting machine also needs to have high structural strength, high temperature resistance, and high electron emission rate. For example, in terms of metal conductivity, silver is the best, followed by copper, gold, and aluminum. Although the conduc...

Abstract

The invention provides an electrode tip for a plasma cutting machine, which comprises a casing pipe, a carrier, an electrode core, a first hard soldering structure and a second hard soldering structure, wherein the casing pipe is hollow and is provided with a first open end and a second open end; and a first flange protrudes out of the first end towards the interior of the casing pipe. The carrier is cylindrical and is provided with a third end and a fourth end; a second flange protrudes out of the third end along the radial direction toward the exterior; and the second flange is fixedly connected to the first flange of the casing pipe by the first hard soldering structure. A convex structure protrudes out of the fourth end towards the interior of the casing pipe; and a depressed structure is formed at the center of the third end axially from outside towards the interior of the convex structure. The electrode core is arranged in the depressed structure and is fixedly connected to the depressed structure by the second hard soldering structure. The electrode tip for the plasma cutting machine has better strength and heat dissipation effect.

Description

technical field [0001] The invention relates to the field of plasma cutting machine processing technology, in particular to an electrode head for a plasma cutting machine. Background technique [0002] Plasma cutting machine is a machine that processes metal materials by means of plasma cutting technology. Plasma cutting is a processing method that uses the heat of the high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece, and uses the momentum of the high-speed plasma to remove the molten metal to form a kerf. It is generally used to cut metals that are difficult to cut , especially for non-ferrous metals (such as: stainless steel, aluminum, copper, titanium, nickel) cutting effect is better, its main advantage is that when cutting metals with small thickness, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets , the speed can reach 5-6 times that of the oxygen cutting method...
