Description

Technical Field

[0001] The utility model relates to the technical field of tungsten electrodes, and particularly relates to a tungsten electrode with excellent electrical and thermal conductivity. Background Art

[0002] Tungsten electrodes are an important type of electrode material, mainly used for TIG (tungsten inert gas welding) and other similar operations. Tungsten electrodes have a high melting point and can withstand welding operations in high-temperature environments. They have good corrosion resistance and can remain stable in a variety of chemical environments. The high-density characteristic of tungsten makes the electrode more stable during the welding process. Tungsten electrodes have excellent electrical and thermal conductivity, which helps with energy transfer during the welding process.

[0003] In existing tungsten electrodes, when the tip at the front end of the tungsten electrode is damaged during welding, it is prone to inconvenient repair or overall scrapping. At the same time, during the use of the tungsten electrode, its rear end is also inconvenient for efficient heat dissipation. For this reason, we propose a tungsten electrode with excellent electrical and thermal conductivity. Summary of the Utility Model

[0012] 1. In the present utility model, during the use of the tungsten electrode, after the electrode tip at the front end is damaged due to excessive current or unskilled operation, the movable cap at the outer end of the electrode head can be disassembled to replace the electrode head quickly and conveniently, thereby reducing the problem of the overall scrapping of the tungsten electrode caused by the damage of the electrode head in the tungsten electrode.

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0023] The following describes a tungsten electrode with excellent electrical and heat conduction performance provided by some embodiments of the present utility model in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combined with Figures 1-3As shown in the figure, a tungsten electrode with excellent electrical and thermal conductivity provided by the utility model includes: a tungsten copper alloy electrode handle 100, a replacement component 200, and a heat dissipation component 300; the replacement component 200 includes a notch 201 opened at the front end of the tungsten copper alloy electrode handle 100, an electrode head 202 movably installed at the front end of the tungsten copper alloy electrode handle 100, a chuck 203 fixedly arranged at the rear end of the electrode head 202, a fixing piece 204 fixedly arranged at the rear end of the chuck 203, a movable cap 205 movably installed at the outer end of the electrode head 202, and a heat dissipation cylinder 206 fixedly installed at the outer end of the tungsten copper alloy electrode handle 100; a threaded port 207 is also opened at the front end of the heat dissipation cylinder 206, the movable cap 205 is movably and fittingly installed at the outer end of the threaded port 207, and the fixing piece 204 and the notch 201 are matched with each other.

[0026] Specifically, the tungsten electrode is an important electrode material, mainly used for TIG welding and other similar work; during the use of this tungsten electrode, after the tip of the electrode head 202 at its front end is damaged due to excessive current or unskilled operation, the movable cap 205 at the outer end of the electrode head 202 can be removed to replace the electrode head 202 quickly and conveniently, thereby reducing the problem of the overall scrapping of the tungsten electrode caused by the damage of the electrode head 202. At the same time, the notch 201 opened at the front end of the tungsten copper alloy electrode handle 100 is mainly used for clamping with the fixing piece 204 at the rear end of the electrode head 202, so as to ensure the tight connection between the tungsten copper alloy electrode handle 100 and the electrode head 202. The chuck 203 arranged at the rear end of the electrode head 202 is mainly used for tightly pressing the electrode head 202 after the movable cap 205 is installed at the outer end of the threaded port 207.

[0027] Embodiment Two:

[0028] Combined with Figure 4 As shown in the figure, on the basis of Embodiment One, the heat dissipation component 300 includes an installation cavity 301 opened in the heat dissipation cylinder 206, and cooling bars 302 and heat conduction bars 303 are respectively arranged in the installation cavity 301 in a staggered manner, and a coolant 304 is filled in each of the cooling bars 302.

[0029] Specifically, the tungsten copper alloy electrode handle 100 at the rear end of the electrode head 202, the cooling bars 302, the heat conduction bars 303 and the heat dissipation cylinder 206 installed at the outer end of the tungsten copper alloy electrode handle 100 also enable this tungsten electrode to have good electrical and thermal conductivity during use. The coolant 304 filled in the cooling bars 302 can also ensure its excellent heat dissipation effect.

[0030] The working principle and usage process of the utility model:

[0031] After the electrode head 202 at the front end of the tungsten electrode is deformed and damaged during welding, the movable cap 205 at the front end of the heat dissipation cylinder 206 can be unscrewed to remove the damaged electrode head 202 at the front end of the tungsten copper alloy electrode shank 100. After a new electrode head 202 is snap-fitted and installed at the front end of the tungsten copper alloy electrode shank 100 through the fixing piece 204 at the rear end, the movable cap 205 at the outer end of the threaded port 207 is reinstalled to lock the new electrode head 202 during use. During the use of the new electrode head 202, the heat generated at its upper end can be absorbed, conducted, and dissipated to the external cooling strip 302, heat conduction strip 303, and heat dissipation cylinder 206 through the tungsten copper alloy electrode shank 100 at the rear end, thereby quickly reducing the temperature at the upper end of the electrode head 202 and increasing its service life.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
