Problems solved by technology

[0002] In the process of preparing the ceramic coating blade, it is necessary to spray the coating blade several times. At present, the commonly used spraying method is plasma spraying. In plasma spraying, the moving speed of the spray gun and the unit of the powder feeder are adjusted. Time to send the component, so as to adjust the thickness of the final sprayed coating, but the coating blade is usually preheated before plasma spraying, after preheating, the plasma flame flow from the spray gun will raise the local temperature of the coating blade to the spraying process The temperature to be reached and sprayed at the same time, but due to the different thicknesses of the coatings, the spray gun moves at different speeds during spraying, which will result in when the spray gun moves at a slower speed, there will be a partial area of ​​the coating blade in contact with the plasma flame flow time Longer, so that the temperature rise in the local area is too high, resulting in thermal deformation or excessive thermal stress, which affects the quality of the finished product of the ceramic coating blade

Abstract

The invention discloses a coating spraying device of a ceramic coating scraper. By setting a spraying platform and a plasma spraying mechanism, the coating scraper placed on the spraying platform is sprayed; the moving speed of a spray gun is measured by setting a speed measuring module; the position of the spray gun is measured by setting a positioning module, and a cooling mechanism is set to bemovable; and when a control module obtains the information measured by the speed measuring module and the positioning module, the position and the moving speed of the spray gun are obtained, so thatthe cooling mechanism is moved to the response position under the spray gun to cool the local area of the coating scraper, and the working power of the cooling mechanism is adjusted according to the moving speed of the spray gun. When the moving speed of the spray gun is slower, the working power of the cooling mechanism is improved to balance the temperature rise brought by the contact time of aplasma flame flow, so that the situation that the temperature rise is too high in the local area of the coating scraper so as to result in excessive thermal deformation or thermal stress to affect thefinal product quality of the ceramic coating scraper is avoided.

Description

technical field [0001] The invention relates to the technical field of preparation of a ceramic coating blade, in particular to a ceramic coating blade coating spraying device. Background technique [0002] In the process of preparing the ceramic coating blade, it is necessary to spray the coating blade several times. At present, the commonly used spraying method is plasma spraying. In plasma spraying, the moving speed of the spray gun and the unit of the powder feeder are adjusted. Time to send the component, so as to adjust the thickness of the final sprayed coating, but the coating blade is usually preheated before plasma spraying, after preheating, the plasma flame flow from the spray gun will raise the local temperature of the coating blade to the spraying process To reach the temperature and spray at the same time, but due to the different thickness of the coating, the spray gun moves at different speeds during spraying, which will cause when the spray gun moves at a s...
