Portable carbon arc air gouging nozzle

Abstract

The invention discloses a portable carbon arc air gouging nozzle. The nozzle comprises a conical shell, wherein a carbon rod hole is formed in the top of the conical shell, and an air inlet handle isarranged on one side of the conical shell, and consists of a first pipe and a second pipe; the end, away from the second pipe, of the first pipe remote is fixedly connected with the outer side of theconical shell; a transverse chute is formed in the side, close to the air inlet handle, of the conical shell, and communicates with the first pipe; an inclined air outlet is formed in the inner wall of the bottom of the transverse chute; a first annular groove is formed in the outer side of the second pipe, and the side, close to the first pipe, of the first annular groove, is arranged as an opening. The nozzle is reasonable in design, practical and portable; the total length of the air inlet handle can be conveniently and quickly adjusted and fixed as required, automatic retraction in use canbe effectively avoided, the air inlet amount is convenient to adjust, the sealing effect can be improved under cooperation of two sealing rings, so that air leakage is prevented, and use requirementsare met.

Description

Technical field [0001] The invention relates to the technical field of carbon arc gouging nozzles, in particular to a convenient carbon arc gouging nozzle. Background technique [0002] Carbon arc gouging refers to the use of carbon rods or graphite rods as electrodes to generate arcs with the workpiece to melt the metal, and use compressed air to blow off the molten metal. A method of surface processing grooves. In welding production, it is mainly used To plan grooves, eliminate weld defects and back root removal. At present, manual carbon arc gouging is common on the market. It has great flexibility and can be operated in all positions. It is very simple. It is mainly used in root removal and groove opening. Especially the medium and thick plate butt grooves, and the pipe butt U-shaped grooves; the existing portable carbon arc gouging nozzles are mostly composed of a cone-shaped gouging nozzle head and an air intake handle. Holes for rods or graphite rods. [0003] The length o...

Problems solved by technology

[0003] The length of the air intake handle of the existing portable carbon arc gouging nozzle has the disadvantage that it is not easy to adjust and fix, and the air output is mostly non-adjustable. In some special welding, if it is necessary to go deep into the machine or the shelf When processing grooves on the inner side, the length of the air intake handle needs to be sufficient to reach the place to be processed, and if a longer air intake handle is directly installed, it will affect the processing of the outer part and take up a large space, making it not portable. It cannot meet the needs of use, so we propose a convenient carbon arc gouging nozzle to solve the above problems
