Description

A carbon dioxide gas shielded welding torch structure

technical field

The utility model belongs to the technical field of secondary protection welding, in particular to a carbon dioxide gas shielded welding torch structure.

Background technique

Carbon dioxide gas shielded welding is generally referred to as "secondary protection welding". The second protection welding process is suitable for welding various large-scale steel structure projects of low-carbon steel and low-alloy high-strength steel. It has high welding productivity, good crack resistance, and small welding deformation. Adapt to a wide range of deformation, and can weld thin and medium-thick plates. At present, the protective tip of the welding torch in the prior art is more likely to adhere to welding slag during the welding process and block the inner wall of the welding tip, so that cleaning is very difficult, time-consuming and laborious, and has a low service life.

Utility model content

In order to achieve the above object, the utility model provides the following technical solutions: a carbon dioxide gas shielded welding torch structure, including a barrel head and a protective piece, the outer side of the lower end of the barrel head is provided with a first thread groove, the protective piece The inner side is provided with a second thread groove, and the barrel head and the guard are screwed through the first thread groove and the second thread groove.

Preferably, the protective part includes a twist sleeve, the second thread groove is arranged on the inner side of the twist sleeve, the bottom of the twist sleeve is provided with a bottom ring, the inner side of the bottom ring is fixedly connected with a protective lining, and the protection The liner fits snugly on the inside of the barrel head.

Preferably, the barrel head is a substrate made of stainless steel, and the guard is a substrate made of copper.

Preferably, the protective member is integrally formed.

Preferably, the upper end of the protective lining is provided with a bevel.

Preferably, the protective lining has a thickness of 4mm-6mm.

The technical effects and advantages of the utility model: the structure of the carbon dioxide gas shielded welding torch can effectively remove the blockage of the gun barrel head, avoid affecting the normal operation of welding, and improve the welding efficiency; the utility model has reasonable design, simple structure and low cost. Inexpensive, suitable for production and popularization.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model provides a carbon dioxide gas shielded welding torch structure as shown in Figures 1-3, comprising a barrel head 1 and a protective piece 2, the barrel head 1 is a substrate made of stainless steel, and the protective piece 2 is a matrix made of red copper material, the outer side of the lower end of the barrel head 1 is provided with a first thread groove 11, the inner side of the protective part 2 is provided with a second thread groove 24, the barrel head 1 and the protective part 2 are threadedly connected through the first thread groove 11 and the second thread groove 24.

Further, the protective part 2 includes a twist sleeve 21, the second thread groove 24 is arranged on the inside of the twist sleeve 21, the bottom of the twist sleeve 21 is provided with a bottom ring 22, and the inside of the bottom ring 22 is fixedly connected to There is a protective inner lining 23, the thickness of the protective inner lining 23 is 4mm-6mm, and the protective inner lining 23 is connected with the inner side of the barrel head 1 to prevent foreign matter from entering the gap and affecting welding.

Further, the protective member 2 is integrally formed to increase strength and structural stability.

Further, the upper end of the protective lining 23 is provided with a bevel, which can remove foreign matter on the barrel head 1 when it is rotated and inserted.

Working principle: When welding, when the inner side of the barrel head 1 is blocked, the protective piece 2 is rotated and inserted into the inside of the barrel head 1, so that the blockage falls off, and the protective piece 2 can also be installed on the inside of the barrel head 1 during welding On the gun barrel head 1, it is convenient to disassemble and assemble, flexible and efficient, easy to clean internal blockages, and improves welding efficiency.
