Description

Novel MIG water cooling gun neck

Technical Field

The invention relates to the technical field of welding gun structures, in particular to a novel MIG water cooling gun neck.

Background

MIG welding refers to an arc welding method in which a consumable electrode is used and an external gas is used as an arc medium to protect a metal droplet, a weld pool, and high-temperature metal in a weld zone, and is called gas metal arc welding. The inert gas (Ar or He) shielded arc welding method using a solid wire is called Metal Inert Gas (MIG) welding.

The existing MIG water-cooling gun neck has the problems of complex cooling structure, various welding accessories, water leakage, easy damage to a welding gun, high cost investment and influence on service life and efficiency.

Disclosure of Invention

The present invention is directed to a novel MIG water cooling gun neck to solve the above problems.

In order to achieve the purpose, the invention provides the following technical scheme: a novel MIG water cooling gun neck comprises an inner guide pipe, wherein a water cooling block is arranged at one end of the inner guide pipe, an air inlet pipe joint is arranged on the water cooling block, and the air inlet pipe joint is communicated with the inner guide pipe; and the end surface of the water cooling block is provided with a water inlet pipe connector and a water outlet pipe which are communicated with the water cooling block.

Preferably, the inner guide pipe, the water outlet pipe, the air inlet pipe joint, the water inlet pipe joint and the water cooling block are fixedly connected in a silver soldering mode.

Preferably, the water outlet pipe is provided with a locking nut.

Compared with the prior art, the invention has the beneficial effects that: compared with the traditional cooling gun neck, the external cooling gun neck has the advantages that the external pipe for external cooling water flow is deleted, so that the welding point for welding the external pipe is omitted, the water leakage point is reduced, the traditional cooling loop is simplified, the front-end complex accessories and processes are omitted, the accessories are simple, the welding points are few, the performance is stable, the fault probability is reduced, the stability of the product performance is improved, and the working efficiency is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, the present invention provides a technical solution: a novel MIG water cooling gun neck comprises an inner guide pipe 1, wherein a water cooling block 2 is arranged at one end of the inner guide pipe 1, an air inlet pipe joint 4 is arranged on the water cooling block 2, and the air inlet pipe joint 4 is communicated with the inner guide pipe 1; and the end surface of the water cooling block 2 is provided with a water inlet pipe joint 5 and a water outlet pipe 3, and the water inlet pipe joint 5 and the water outlet pipe 3 are communicated with the water cooling block 2.

Further, the inner guide pipe 1, the water outlet pipe 3, the air inlet pipe joint 4, the water inlet pipe joint 5 and the water cooling block 2 are fixedly connected in a silver soldering mode.

Furthermore, a locking nut is arranged on the water outlet pipe 3.

The working principle is as follows: the outer part of the inner conduit 1 provided by the scheme is not provided with the outer conduit 6 structure, so that welding spots are reduced, water leakage points are reduced, and the traditional cooling loop is simplified.

Meanwhile, the outer conduit 6 is removed, the outer diameter of the inner conduit 1 is made to be as large as that of the outer conduit 6, so that the sectional area of the inner conduit is correspondingly increased, and the cooling effect of the part with the outer conduit omitted is compensated.

The traditional cooling circuit is simplified, complex accessories and processes at the front end are omitted, the accessories are simple, the number of welding points is small, and the performance is stable, so that the fault probability is reduced, the stability of product performance is improved, and the working efficiency is improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
