Abstract

The invention relates to the field of electric arc machining, in particular to a high-speed electric arc machining device with an inert gas protection function. The technical problems that when the inner wall of a corrugated pipe is sprayed, the thickness of a sprayed protection layer is not uniform, the protection effect is reduced, and the service life of the corrugated pipe is shortened are solved. According to the technical scheme, the high-speed electric arc machining device with the inert gas protection function comprises a supporting plate, clamping mechanisms, a spraying mechanism and a sealing mechanism, the clamping mechanisms are arranged on the upper side face of the supporting plate, the spraying mechanism slides on the left portion of the clamping mechanisms, and the sealing mechanism is arranged on the right side of the spraying mechanism; the spraying mechanism and the sealing mechanism are matched with the inner wall of the corrugated pipe. By designing the sealing mechanism, the situation that in the spraying process, generated high-temperature metal particles and oxygen in air are oxidized, and the protection effect of the protection layer is reduced is avoided, and by designing the spraying mechanism, the situation that the sprayed protection layer is not uniform, and the corrosion resistance effect is reduced is avoided.

Description

technical field [0001] The invention relates to the field of electric arc machining, in particular to a high-speed electric arc machining device with an inert gas protection function. Background technique [0002] Arc spraying is a thermal spraying technology and an important part of surface engineering. In the past 40 years of development, with the continuous development and updating of spraying equipment, spraying materials and spraying processes, arc spraying technology has achieved a leap forward. The development and promotion of application has become one of the most eye-catching technologies in the field of thermal spraying. A protective layer is sprayed on the metal surface by arc spraying, which effectively improves the wear resistance and corrosion resistance of the metal, but in the process of spraying It is necessary to grasp the uniform thickness of the sprayed protective layer. When the thickness is not uniform, the protective effect of the protective layer will...
