Description

Technical Field

[0001] The utility model relates to the technical field of thermal spraying, in particular to a thermal spraying device for preparing electrical appliance combined housing parts. Background Art

[0002] Thermal spraying technology is a technology that uses a high-temperature heat source (such as an arc, flame or plasma) to heat metal or non-metal materials to a molten or semi-molten state, and then atomizes it with a high-speed airflow and sprays it onto the surface of the substrate to form a coating. This technology can effectively improve the physical and chemical properties of the surface of the shell parts, such as enhancing the ability to resist wear, corrosion, high-temperature oxidation and electrochemical corrosion. At the same time, it can also give the shell parts electromagnetic shielding, conductivity or insulation functions by selecting different spraying materials.

[0003] In the process of preparing electrical assembly housing components, due to the complex shapes and different sizes of the components, there are high requirements for the uniformity and bonding strength of the protective coating. Traditional surface treatment methods such as electroplating and painting may be difficult to meet these requirements, while thermal spraying technology has good adaptability and flexibility, and can achieve overall, continuous and uniform coating of complex geometric shapes and large-sized workpieces, significantly improving the quality and service life of the housing components. During the heating process, the material is easily heated unevenly, affecting the spraying effect or causing blockage of the pipeline. Therefore, it is necessary to propose a thermal spraying device for the preparation of electrical assembly housing components. Utility Model Content
