Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, and specifically relates to a laser cladding head. Background Technique

[0002] A laser cladding head mainly consists of a connecting component, an optical component, and a powder feeding component. The laser equipment is connected to the powder feeder through the laser cladding head. The preset powder is quickly scanned by a high-energy laser beam and melted and solidified instantly. The base metal is melted into a thin layer accordingly. Molecular or atomic-level interdiffusion occurs rapidly in a very narrow area at the interface between the two, and at the same time, a firm metallurgical bonding layer is formed, thereby significantly improving various properties of the base, such as hardness, wear resistance, and corrosion resistance. There is an existing patent for a laser cladding head, with the patent publication number CN111690929A, which discloses a laser cladding head including a nozzle body. The nozzle body is a hollow cylindrical structure with openings at both ends. The upper and lower ends of the inner cavity of the nozzle body are respectively a cylindrical cavity and a conical cavity that are connected. The lower opening of the nozzle body is smaller than the upper opening. A condenser lens is hermetically connected to the upper end of the nozzle body. A powder channel and a protective gas channel are provided on the nozzle body. The powder channel includes a main channel and multiple feeding channels. A switching device for switching the feeding channels to communicate with the main channel is provided on the nozzle body. In the present invention, multiple feeding channels can be opened separately to realize the alternate filling of multiple powders, so as to realize the rapid switching of the filling of powders with different particle sizes according to the cladding requirements, and realize the replacement of powder filling without stopping the machine, ensuring the continuity of processing.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: when it is in use, although it can be switched through the powder channel, when it is in use, due to the lack of an effective flow concentrating structure, when the powder is ejected, it is very easy for the powder to deviate due to uneven distribution, which will further affect the laser cladding work. Therefore, we propose a laser cladding head to solve the above problems. Summary of the Invention
