A conductive nozzle reinforcement

Abstract

This utility model relates to the field of conductive nozzle technology and discloses a conductive nozzle reinforcement, including a reinforcement with a tapered outer wall at one end and a wire-passing channel hole in the middle. The wire-passing channel hole has a stepped inner hole and a flared inlet end. The outer wall of the reinforcement has a detachable structure. This utility model facilitates the smooth entry of welding wire by using a stepped inner hole and a flared inlet end for the wire-passing channel hole. The detachable structure on the outer wall of the reinforcement makes it easy to install onto the conductive nozzle, thus facilitating replacement of the reinforcement and avoiding the high cost of replacing the entire nozzle. Furthermore, by replacing only the reinforcement instead of the entire conductive nozzle, the number of replacements is reduced, improving wear resistance.

Description

Technical Field

[0001] This utility model relates to the field of conductive nozzle technology, specifically a conductive nozzle reinforcement. Background Technology

[0002] The contact tip refers to the shape of its inner hole: round, oval, triangular, square, etc. It is manufactured from materials such as brass, copper, chromium zirconium copper, and beryllium copper. Common specifications are 15ak, 24kd, 36kd, and Panasonic type, etc. The inner diameter of the contact tip must be selected according to the diameter of the welding wire. Typically, the diameter of the contact tip is about 0.02mm larger than the diameter of the welding wire.

[0003] The wire feed end of the original conductive tip suffers severe wear due to high-speed friction of the welding wire and high-temperature environment, requiring replacement every 25 pieces. Frequent replacement leads to high costs. Traditional conductive tips mostly use a single material, such as pure copper, which is not wear-resistant enough. Although wear-resistant materials are used in other parts of the conductive tip, the local reinforcement of the wire feed end is not addressed, resulting in a limited overall lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a conductive nozzle reinforcement.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a conductive nozzle reinforcement, including a reinforcement, one end of which has a tapered outer wall, a wire threading channel hole in the middle of the reinforcement, the wire threading channel hole having a stepped inner hole, the entrance end of the wire threading channel hole having a flared mouth, and the outer wall of the reinforcement having a structure for easy disassembly and assembly.

[0007] As a preferred embodiment of this utility model, the reinforcing member is made of chromium-molybdenum-vanadium alloy steel.

[0008] As a preferred technical solution of this utility model, the inner surface of the wire-threading channel hole is polished.

[0009] As a preferred embodiment of this utility model, the easily detachable structure includes an external threaded connection portion provided on the outer wall of the reinforcing member.

[0010] As a preferred embodiment of this utility model, the end of the external threaded connection of the reinforcing member is provided with an elastic washer.

[0011] As a preferred embodiment of this utility model, the innermost layer of the inner wall of the wire threading channel hole is made of a high-conductivity copper alloy, the middle layer of the wire threading channel hole is made of high-strength steel, and the outermost layer of the wire threading channel hole is made of a wear-resistant ceramic coating.

[0012] As a preferred embodiment of this utility model, the outer end of the reinforcing member is annular and has operating grooves at equal intervals.

[0013] As a preferred embodiment of this utility model, the easily detachable structure includes an annular protrusion on the outer wall of the reinforcing member.

[0014] The beneficial effects of this utility model are:

[0015] This type of conductive tip reinforcement has a stepped inner hole for the wire threading channel, and the inlet end of the wire threading channel is designed as a flared mouth to facilitate the smooth entry of the welding wire. The outer wall of the reinforcement has a detachable structure, which makes it easy to install the reinforcement onto the conductive tip. This facilitates the replacement of the reinforcement and avoids the high cost of replacing the entire conductive tip. Furthermore, only the reinforcement needs to be replaced, instead of the entire conductive tip, which reduces the number of replacements and improves wear resistance. Attached Figure Description

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example 1: As Figure 1 and Figure 2 As shown, this utility model discloses a conductive nozzle reinforcement, including a reinforcement 1. One end of the outer wall of the reinforcement 1 is tapered, and a wire-passing channel hole 2 is provided in the middle of the reinforcement 1. The wire-passing channel hole 2 is a stepped inner hole, and the entrance end of the wire-passing channel hole 2 is a flared mouth. The outer wall of the reinforcement 1 is provided with a detachable structure 3. The stepped inner hole and the flared mouth of the wire-passing channel hole 2 facilitate the smooth entry of welding wire. The detachable structure 3 on the outer wall of the reinforcement 1 makes it easy to install the reinforcement 1 onto the conductive nozzle, thereby facilitating the replacement of the reinforcement 1 and avoiding the high cost of replacing the entire nozzle. Furthermore, only the reinforcement needs to be replaced, instead of replacing the entire conductive nozzle, which reduces the number of replacements and improves wear resistance.

[0026] The reinforcing member 1 is made of chromium-molybdenum-vanadium alloy steel, which has high hardness, high temperature resistance and excellent wear resistance. Compared with conventional copper-based materials, the wear resistance of the reinforcing member 1 is significantly improved, which directly extends the life of the conductive tip.

[0027] The inner surface of the wire-threading channel hole 2 is polished, which further reduces the coefficient of friction.

[0028] The easily detachable structure 3 includes an external threaded connection part 4 on the outer wall of the reinforcing member 1, a wire-passing channel 8 inside the conductive nozzle 7, and an internal threaded connection part 9 on the inner wall of the wire-passing channel 8 that is threadedly connected to the external threaded connection part 4 (e.g., ...). Figure 4 As shown in the figure, it is used to fix the reinforcing member 1 to the conductive nozzle 7.

[0029] Among them, the end of the external threaded connection part 4 of the reinforcing member 1 is provided with an elastic washer 5 to prevent the reinforcing member 1 from loosening due to high-frequency vibration.

[0030] Specifically, such as Figure 6 As shown, the innermost layer of the inner wall of the wire threading channel hole 2 is made of a high-conductivity copper alloy 11, the middle layer of the wire threading channel hole 2 is made of high-strength steel 12, and the outermost layer of the wire threading channel hole 2 is made of a wear-resistant ceramic coating 13. By balancing conductivity, mechanical strength and wear resistance through a gradient structure, the performance limitations of a single material are overcome, and the situation of easy peeling of traditional coatings is avoided.

[0031] The outer end of the reinforcing member 1 is annular and has equidistant operating grooves 14, which facilitates the disassembly of the reinforcing member 1 using a special wrench.

[0032] During disassembly, use a special wrench to unscrew the reinforcing part 1. During installation, align the new reinforcing part 1 with the wire threading channel 8 and rotate the reinforcing part 1 to complete the replacement. There is no need to disassemble the entire conductive nozzle 7. The wire threading channel hole 2 is designed with a stepped inner hole and the inlet end of the wire threading channel hole 2 is designed with a flared mouth to facilitate the smooth entry of welding wire. The outer wall of the reinforcing part 1 has a removable structure 3, which makes it easy to install the reinforcing part 1 onto the conductive nozzle. This makes it easy to replace the reinforcing part 1, avoiding the high cost of replacing the entire conductive nozzle. Moreover, only the reinforcing part needs to be replaced, instead of the entire conductive nozzle, which reduces the number of replacements and improves wear resistance.

[0033] Example 2, as Figure 3 As shown, a further improvement has been made based on Embodiment 1. The easily detachable structure 3 includes an annular protrusion 6 on the outer wall of the reinforcing member 1, and an elastic groove 10 corresponding to the annular protrusion 6 is provided on the inner wall of the wire-threading channel 8 of the conductive nozzle 7. Figure 5 As shown), it is pressed in axially.

[0034] During disassembly, use a special wrench to press the elastic groove 10 on the conductive nozzle 7 to separate the annular protrusion 6 from the elastic groove 10. During installation, align the new reinforcing member 1 with the elastic groove 10 in the wire threading channel 8 and press the reinforcing member 1 in to complete the replacement of the reinforcing member 1. This type of conductive nozzle reinforcing member has a stepped inner hole in the wire threading channel hole 2, and the entrance end of the wire threading channel hole 2 is a flared mouth to facilitate the smooth entry of the welding wire. The outer wall of the reinforcing member 1 has a removable structure 3, which makes it easy to install the reinforcing member 1 onto the conductive nozzle, thereby facilitating the replacement of the reinforcing member 1 and avoiding the high cost of replacing the entire conductive nozzle. Moreover, only the reinforcing member needs to be replaced, instead of replacing the entire conductive nozzle, which reduces the number of replacements and improves wear resistance.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
