Description

Technical Field

[0001] The utility model relates to the technical field of chromium-zirconium-copper microporous tubes, in particular to a chromium-zirconium-copper microporous tube for a conductive nozzle. Background Art

[0002] Chrome-zirconium copper microporous tubes are commonly used in the manufacture of various gas shielded welding contact tips, electrospray nozzles, and electrode adapters. Chrome-zirconium copper possesses excellent electrical conductivity and can quickly conduct current, effectively reducing energy loss and improving welding efficiency during the welding process. Its high strength and hardness allow the contact tips to withstand the friction and impact of the welding wire during use, making them less susceptible to deformation and wear. This ensures their dimensional accuracy and shape stability, extending their service life.

[0003] For example, prior art publication number CN208906341U describes a chromium-zirconium-copper microporous tube for a conductive nozzle. This utility model includes a handle, a hook, a buckle, a cover, a microporous tube body, a reinforcing rib layer, an X-shaped metal skeleton, a silicon carbide layer, a through hole, an elastic fiber core, and release paper. The through hole is provided within the microporous tube body, and a reinforcing rib layer and a silicon carbide layer are sequentially provided between the through hole and the microporous tube body. The X-shaped metal skeleton is provided within the reinforcing rib layer, and the silicon carbide layer is provided within the reinforcing rib layer. The reinforcing rib layer and the silicon carbide layer improve the hardness and high-temperature resistance of the tube, thereby extending the service life of the conductive nozzle.

[0004] However, the above-mentioned prior art still has the following problem: the chromium-zirconium-copper microporous tube of the conventional contact tip relies solely on its own heat dissipation. Over long-term use, the microporous tube's own temperature rises, exacerbating lattice vibrations, increasing electron scattering, and reducing conductivity, thereby affecting subsequent welding results. To address this issue, the present invention provides a chromium-zirconium-copper microporous tube for a contact tip with enhanced heat dissipation. Utility Model Content

The hardness of the microporous tube body can be improved by the bushing, and the cooling sleeve can improve the heat dissipation effect of the microporous tube body. Moreover, the cooling tube in the cooling tube can transport coolant, and use the flowing coolant to take part of the heat out of the drain pipe, thereby further improving the heat dissipation effect of the microporous tube body, avoiding the microporous tube body from having too high a temperature and reducing the conductivity, affecting the subsequent normal use, so as to solve the problems arising from the above-mentioned background technology.

[0012] In a preferred embodiment, the bushing and the cooling jacket are both threadedly connected to the microporous tube body via second fastening bolts, so as to improve the firmness of the bushing and the cooling jacket in the microporous tube body.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Refer to the instruction manual Figure 1-Figure 5 The utility model provides a chromium-zirconium-copper microporous tube for a conductive nozzle, including a microporous tube body 1, a threaded joint 2 being detachably connected to the bottom of the microporous tube body 1, a center hole 3 being opened inside the microporous tube body 1 and the threaded joint 2, a bushing 4 being provided inside the center hole 3, and the provision of the bushing 4 can improve the hardness of the microporous tube body 1 and can improve the service life of the tube body 1 to a certain extent.

[0026] The outer wall of the bushing 4 is provided with a cooling assembly 5, and the cooling assembly 5 includes a cooling jacket 51. The bushing 4 and the cooling jacket 51 are both threadedly connected to the microporous tube body 1 through a second fastening bolt 10, which is used to improve the firmness of the bushing 4 and the cooling jacket 51 in the microporous tube body 1. A cooling pipe 52 is provided inside the cooling jacket 51, and one end of the cooling pipe 52 passes through the cooling jacket 51 and the microporous tube body 1 and extends to the outside of the microporous tube body 1. A liquid inlet pipe 53 and a liquid discharge pipe 54 connected to the cooling pipe 52 are passed through the inside of the threaded joint 2. Two receiving grooves 7 are provided at the bottom of the microporous tube body 1, and the liquid inlet pipe 53 and the liquid discharge pipe 54 are respectively arranged in the two receiving grooves 7.

[0027] Two symmetrically distributed circular grooves 8 are provided on the outer wall surface of the threaded joint 2, and the liquid inlet pipe 53 and the liquid discharge pipe 54 are respectively arranged in the two circular grooves 8. The liquid inlet pipe 53 and the liquid discharge pipe 54 are stored in the circular grooves 8 to prevent the liquid inlet pipe 53 and the liquid discharge pipe 54 from bulging outward and being damaged during transportation. A plurality of heat dissipation fins 6 distributed in a circular array are fixedly provided on the outer wall surface of the microporous tube body 1. With the help of the heat dissipation fins 6, the air flow rate at the outer wall of the microporous tube body 1 can be increased, thereby improving the heat dissipation effect.

[0028] In actual use, a bushing 4 and a cooling sleeve 51 are arranged inside the microporous tube body 1. The bushing 4 is made of wear-resistant material, such as silicon carbide.

Specifically, the cleaning assembly 9 includes an annular scraper 91, and the inner wall of the annular scraper 91 is provided with cleaning grooves 92 with the same number as the heat sink fins 6, and the heat sink fins 6 are arranged in the cleaning grooves 92.

[0030] By moving the annular scraper 91 upward, the cleaning groove 92 on the inner wall of the annular scraper 91 contacts the surface of the heat dissipation fin 6, which can scrape off the dust and debris adhering to the surface of the microporous tube body 1 and the surface of the heat dissipation fin 6, thereby assisting the staff to clean quickly, which is easy to operate and highly practical.

[0031] In addition, a first fastening bolt 93 is threadedly connected to the outer wall of the front end of the annular scraper 91, and a threaded hole 94 compatible with the first fastening bolt 93 is opened on the front end surface of the microporous tube body 1. The first fastening bolt 93 is arranged in the threaded hole 94 and is threadedly connected to the threaded hole 94. After cleaning, the staff can screw the first fastening bolt 93 into the threaded hole 94 to fix the annular scraper 91, thereby preventing the annular scraper 91 from shaking and affecting the normal use of the microporous tube body 1.

[0032] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
