Description

Four-side air supply type carbon arc gouging gun head

Technical Field

The utility model relates to a carbon arc gouging machine, in particular to a four-side air supply type carbon arc gouging machine gun head.

Background

The carbon arc gouging is a processing technique for gouging and cutting a metal base metal by utilizing high-temperature current generated between a carbon electrode and the metal to heat the metal to a molten state locally and simultaneously blowing out the molten metal by utilizing high-speed air flow of compressed air.

Compressed air is sprayed out from an air supply hole at one side of a jaw when the side air supply type carbon arc gouging gun works, so that the carbon rod cannot be uniformly cooled, the compression effect on an electric arc is not obvious, slag is easily accumulated at the front end of a gouging groove, and the like. For the working environment with narrow space, the side air supply type carbon arc gouging gun is inconvenient to use, so that the gouging effect is poor.

The problems are that:

1. The carbon rod cannot be uniformly cooled:

when the carbon rod cooling device is used, compressed air is blown out from the air supply hole, and the air is only on one side of the carbon rod, so that the carbon rod cannot be uniformly cooled.

2. More slag sticking conditions are caused during grooving:

When the carbon arc gouging is carried out, the blown molten iron is called slag, the surface of the slag is a layer of ferric oxide, and the inside of the slag is metal with high carbon content. If the slag sticks to both sides of the gouge, so-called sticking slag. The sticking is mainly caused by the fact that the compressed air is too small. The compressed air is concentrated on one side of the side air supply type carbon arc gouging gun, so that the compressed air on the other side is less, and slag sticking is easy to occur.

3. Due to the position of the air supply hole, the limit of the using position of a narrow space exists in construction.
