Abstract
Description
Technical Field
[0001] This utility model relates to the field of conductive nozzle technology, and in particular to an adjustable MIG / MAG conductive nozzle. Background Technology
[0002] A conductive tip is a welding consumable used to transmit welding current to the welding wire during the welding process. The conductive tip is located at the very front of the welding gun, and its main function is to transmit welding current to the welding wire just before the welding wire touches the molten pool.
[0003] In the existing technology, most contact tips are cylindrical. Once the inner diameter of the contact tip is worn, it becomes unusable (damage caused by improper operation; when the welding torch is closed, the instantaneous current is too high, and the contact tip is easily melted and fused to the welding wire). Once the inner diameter of the contact tip changes, it can no longer be used, which will result in a waste of resources. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable MIG welding conductive nozzle.
[0005] The technical solution adopted by this utility model is: an adjustable MIG welding conductive nozzle, including a conductive nozzle body, a threaded post fixedly connected to the outside of the conductive nozzle body, a through hole through the threaded post and the conductive nozzle body, and a first through opening at one end of the conductive nozzle body.
[0006] In one embodiment, the outer sides of the conductive nozzle body are provided with flat grooves and arc-shaped grooves, and the tail of the first through-hole is set as an oblique opening.
[0007] In one embodiment, one end of the conductive nozzle body is provided with a second through-hole, which penetrates the first through-hole.
[0008] In one embodiment, at least one first through-hole and one third through-hole are provided at one end of the conductive nozzle body, and the first through-hole and the third through-hole are alternately arranged.
[0009] In one embodiment, the angle of the bevel is 10° to 30°.
[0010] In one embodiment, a protrusion is also fixedly connected to the inner wall of the conductive nozzle body;
[0011] In one embodiment, the sidewall of the first through-hole is provided with an arc-shaped groove.
[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, a first through-hole is provided at one end of the conductive tip body, dividing one end of the conductive tip body into two sheet-like structures. Whenever there is wear, pliers are used to clamp the two sides of the conductive tip body towards each other and bend them, and then the welding wire is clamped again. After adjusting the clamping, it can be reused. It is suitable for various types of welding wires, as well as various types and thicknesses, whether for manual welding or robot welding. The end contact is tight, which can ensure the stability of the arc and the contact point does not change. The conductive tip body can be used continuously without causing waste of resources.

Therefore, they should not be construed as limitations on this utility model.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] The following is in conjunction with the appendix Figure 1 —4 provides further explanation of this utility model.
[0022] To address the problems existing in the background art, this application proposes the following technical solution:
[0023] Example 1
[0024] An adjustable MIG welding conductive nozzle includes a conductive nozzle body 1, a threaded post 8 fixedly connected to the outside of the conductive nozzle body 1, a through hole 7 through the threaded post 8 and the conductive nozzle body 1, and a first through opening 2 at one end of the conductive nozzle body 1.
[0025] In a further design, flat grooves 5 and arc-shaped grooves 4 are provided on both sides of the outer side of the conductive nozzle body 1. The flat grooves 5 are designed to facilitate clamping with pliers, and the arc-shaped grooves 4 are designed to facilitate bending of the conductive nozzle. The tail of the first through-hole 2 is designed as a bevel 3 with an angle of 10° to 30°, preferably 15°. In order to ensure stable clamping, a protrusion 6 is also fixedly connected to the inner wall of the conductive nozzle body 1.
[0026] The above technical solution is explained as follows: In this embodiment, a first through-hole 2 is provided at one end of the conductive tip body 1, so that one end of the conductive tip body 1 is divided into two sheet-like structures. In the prior art, the conductive tip body 1 can no longer be used once the inner diameter is worn. In this embodiment, as long as there is wear, take pliers, clamp the two sides of the conductive tip body 1 and bend them towards each other, and clamp the welding wire again. After adjusting the clamping, it can be reused. It can be used for various types of welding wires, as well as various types and thicknesses of welding wires, whether for manual welding or robot welding. The end contact is tight, which can ensure the stability of the arc and the contact point does not change.
[0027] Example 2
[0028] The difference between this embodiment and embodiment one is that in this embodiment, a second through-hole 9 is provided at one end of the conductive nozzle body 1. The second through-hole 9 passes through the first through-hole 2, and the first through-hole 2 and the second through-hole 9 are interleaved to facilitate further adjustment and clamping of the welding wire.
[0029] Example 3
[0030] In this embodiment, unlike in embodiment one, the flat groove 5 and the arc groove 4 are not included. At least one first through-hole 2 and a third through-hole 10 are provided at one end of the conductive nozzle body 1, and the first through-hole 2 and the third through-hole 10 are staggered. In practice, multiple first through-holes 2 and third through-holes 10 can be provided to divide one end of the conductive nozzle body 1 into multiple strips, which facilitates further clamping of the welding wire.
[0031] Example 4
[0032] The difference between this embodiment and embodiment one is that the side wall of the first through-hole 2 is provided with an arc-shaped groove 11.
[0033] The arc-shaped groove 11 facilitates the clamping of the welding wire.
[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
