Description
Technical Field
The utility model relates to a rotary blade field particularly, relates to a rotary blade is firing equipment for surface coating.
Background
The rotary blade brazing technology is a material surface processing technology which forms a coating with special properties (wear resistance and corrosion resistance) on the surface of a rotary blade body by means of the principle of brazing and by utilizing the wetting and spreading of liquid brazing alloy on base metal.
Compared with the traditional coating technology, the braze coating technology has the following characteristics: (1) the coating and the matrix are metallurgically bonded, so that the bonding strength is high; (2) the content range of ceramic phase (carbide, boride, nitride, oxide and the like) or diamond in the coating is wide (0-70%), the structure is uniform and compact, and the porosity is low; (3) the thickness range of the prepared coating is large, and the coating can be prepared into a thin coating of 50-60 mu m or a thick coating of 3-4 mm; (4) the coating has smooth surface, good quality and high processing precision, and only needs little or no processing for general application; (5) the melting temperature of the brazing alloy in the brazing coating material is lower than that of the matrix metal, the matrix metal generally needs to be integrally and uniformly heated in the brazing coating process, the stress between the matrix metal and the coating is small, and the performance change of the matrix metal is small. Due to these characteristics, the brazing coating technology is one of the most effective means for strengthening the soil-contacting cutter of agricultural machinery.
The brazing coating material mainly comprises: (1) typical solder alloys, which have a relatively low melting temperature, are known as low melting point components; (2) hard wear resistant particles (carbides, borides, nitrides, oxides, diamonds, etc.) with high melting points; (3) a binder and a solvent. Generally, after hard wear-resistant particles, solder alloy powder, and a binder and a solvent are sufficiently stirred to form a suspension, the suspension is applied to a portion of a rotary blade body to be brazed by using a brush. Because the rotary tillage cutter body is of a three-dimensional curved structure, the thickness of each smearing layer is not suitable to be too thick (generally 0.05 mm-0.1 mm), otherwise, suspension liquid is easy to flow under the action of gravity. If a thicker coating needs to be obtained, the method can be repeated for coating for many times only after the coating is dried until the required coating thickness is reached, the production efficiency is low, and the uniformity of the coated layer is poor.
In view of this, the present invention is especially provided.
