Description

Technical Field

[0001] The utility model relates to the technical field of plasma spraying, in particular to a coating gun for plasma coating. Background Art

[0002] Plasma spraying is an advanced material surface strengthening and modification technology. It uses a plasma arc driven by direct current as a heat source to heat ceramics, alloys, metals and other materials to a molten or semi-molten state, and sprays them at high speed onto the pre-treated workpiece surface to form a firmly attached surface layer. This technology gives the substrate surface a variety of properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction and sealing, so as to meet the needs of parts under different working conditions. Plasma spraying has ultra-high temperature characteristics and is suitable for spraying high melting point materials. In addition, the particle speed is high during the spraying process, the coating is dense, and the bonding strength is high. At the same time, due to the use of inert gas as the working gas, the spraying material is not easy to oxidize. Plasma spraying technology is widely used in the surface treatment and repair of metal workpieces such as steel, aluminum, and zinc, including automotive parts, mechanical parts, boiler inner walls and other fields. In addition, it also plays an important role in the medical field, such as spraying coatings on the surface of artificial bones to strengthen bones and enhance their affinity. In short, plasma spraying technology has become an indispensable part of modern industrial production with its unique advantages and wide application fields.

[0003] Plasma spraying requires a spray gun. Existing spray guns usually do not have an anti-accidental touch structure when in use. When in use, due to misoperation, the gun may be triggered to spray in places that should not be sprayed, causing economic losses and reduced efficiency.

[0004] Therefore, it is necessary to redesign the spray gun to effectively prevent the existing spray guns from being triggered to spray in places where they should not be sprayed due to misoperation, which usually does not have an anti-accidental touch structure during use, causing economic losses and reduced efficiency.

[0011] As a preferred embodiment of the present invention, the compression spring is located on the top of the lifting plate, and the compression spring is used in conjunction with the lifting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model rotates the knob, and the rotation of the knob drives the screw rod to rotate.
