Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tungsten electrodes, and specifically relates to a tungsten electrode with a heat dissipation structure. Background Art
[0002] Tungsten electrodes are a kind of electrode materials widely used in welding and other similar operations, mainly due to the high melting point, corrosion resistance, high density, and good thermal conductivity and electrical conductivity of tungsten. During high-temperature operations such as welding and cutting, due to the high temperature of the electric arc, a large amount of heat will be generated in the electrode itself. If the heat cannot be dissipated in time, it will cause the temperature of the electrode to rise, thereby affecting the welding quality and even damaging the electrode. Therefore, we propose a tungsten electrode with a heat dissipation structure. Content of the Utility Model
[0003] The utility model aims to solve the problems existing in the prior art or related technologies.
[0004] To this end, the technical solution adopted by the utility model is as follows: a tungsten electrode with a heat dissipation structure, including a tungsten electrode body, a heat dissipation inner sleeve assembly, a fastening assembly, and a heat dissipation outer sleeve assembly. The heat dissipation inner sleeve assembly includes an inner sleeve main body inserted outside the tungsten electrode body and a plurality of first heat dissipation fins arranged on the outer side of the inner sleeve main body. The fastening assembly is arranged at the top of the inner sleeve main body. The heat dissipation outer sleeve assembly includes an outer sleeve main body inserted outside the inner sleeve main body and screwed to the inner sleeve main body, a water inlet pipe arranged on the outer side of the outer sleeve main body, a drain pipe arranged on the right side of the outer sleeve main body, and a plurality of second heat dissipation fins arranged on the outer side of the outer sleeve main body.
[0005] Preferably, the inner sleeve main body is a hollow structure.
[0006] Preferably, the fastening assembly includes a fixing pipe arranged at the top of the inner sleeve main body and a fastening knob threadedly connected to the fixing pipe.
[0007] Preferably, a first sealing ring is arranged on the inner side of the outer sleeve main body, and a second sealing ring is arranged at the front end of the outer sleeve main body.
[0008] Preferably, the outer sleeve main body is a hollow structure.
[0009] Preferably, the water inlet pipe and the drain pipe are fixedly connected to a cooling water supply device through a hose.
[0010] By adopting the above technical solution, the beneficial effects achieved by the present utility model are as follows: By providing a heat dissipation inner sleeve assembly and a heat dissipation outer sleeve assembly, the effect of rapid heat dissipation is achieved without affecting the use of the tungsten electrode. At the same time, by providing a fastening assembly, the position of the heat dissipation structure can be adjusted to adjust the length of the tungsten electrode exposed on the welding torch. During use, the user can insert the heat dissipation inner sleeve assembly onto the tungsten electrode, then insert the heat dissipation outer sleeve assembly outside the heat dissipation inner sleeve assembly and fix it with screws. After fixing, the water inlet pipe and the drain pipe are fixedly connected to the cooling water supply device through hoses. After connection, the cooling water supply device can deliver the cooling water to the middle gap between the heat dissipation outer sleeve assembly and the heat dissipation inner sleeve assembly, and then utilize the heat transfer property for heat dissipation. The first heat dissipation fins and the second heat dissipation fins provided both improve the heat dissipation efficiency by increasing the surface area for rapid heat dissipation. At the same time, the fastening knob of the fastening assembly can be loosened. After loosening, the heat dissipation inner sleeve assembly and the heat dissipation outer sleeve assembly can be moved. After moving to a suitable position, the fastening knob can be tightened to adjust the position of the heat dissipation structure on the tungsten electrode body, so as to facilitate the adjustment of the length of the tungsten electrode exposed on the welding torch when the tungsten electrode is installed in the welding torch.
