Embodiment approach
[0032] As an embodiment of the present invention, the through hole 4 includes a No. 1 hole 41 and a No. 2 hole 42, and the No. 1 hole 41 is close to the scraper 3, and the No. 2 hole 42 is close to the conductive copper joint 5; the No. 1 hole 41 The aperture near the end of the scraper 3 is small, and the aperture of the No. 1 hole 41 away from the end of the scraper 3 is large, and the No. 1 hole 41 is inclined towards the scraper 3; the aperture of the second hole 42 near the end of the conductive copper joint 5 is small, and the No. 2 hole The diameter of the hole 42 away from the end of the conductive copper joint 5 is large, and the second hole 42 is obliquely facing the conductive copper joint 5 .
[0033] During use, during the welding process, by setting No. 1 hole 41 and No. 2 hole 42, when the gas is ejected from the through hole 4, the carbon dioxide gas in the No. 1 hole 41 is blown to the scraper 3, thereby scraping the scraper 3. The welding slag is blown away i...

The invention belongs to the technical field of welding guns, and particularly relates to a welding gun head. The welding gun head comprises a welding gun body, a wire feeding pipe, a conductive copper connector, a lantern ring and a protective sleeve; the wire feeding pipe is fixedly connected to the top end of the welding gun body, and internal elements of the welding gun body are electrically connected with internal elements of the wire feeding pipe; and the conductive copper connector is fixedly connected to the position, located at one end of a switch in the welding gun body, of the wire feeding pipe, and communicates with the wire feeding pipe, and a welding wire penetrates through the conductive copper connector from the wire feeding pipe to come out. When welding work is finished or welding work is carried out for a long time, due to the fact that the protective sleeve is rotationally connected with the lantern ring, a worker rotates the protective sleeve, and the sharp end of a scraping knife is attached to the inner wall of the protective sleeve, so that fine-particle metal welding slag on the inner wall of the protective sleeve is rapidly scraped off, the influence on the welding quality due to excessive welding slag accumulation on the inner surface of the protective sleeve is reduced, and the cleaning degree of the protective sleeve is increased.
Description
technical field [0001] The invention belongs to the field of welding torch technology, in particular to a welding torch head. Background technique [0002] The welding torch refers to the part that performs the welding operation during the welding process. The welding torch uses the high current of the welding machine, and the heat generated by the high voltage gathers at the terminal of the welding torch, melts the welding wire, and the molten welding wire penetrates into the part to be welded. After cooling, the objects to be welded are firmly connected into one. Welding guns are divided into gas welding guns, electric welding guns and secondary welding guns according to their structure. [0003] A patent in the prior art is about a technical solution of a welding torch head. For example, a Chinese patent with application number CN2019108302892 discloses a welding torch head, including a welding tip, a protective sleeve, a connecting pipe and a handle. The protection The...
