Description

Technical Field

[0001] The utility model relates to the field of laser cladding, in particular to a rotary laser cladding head. Background Technique

[0002] Laser cladding technology is a material surface modification technology. By using a high-power density laser beam, under the numerical control of a laser processing system, a very thin micro-melted layer is formed at a specified position on the surface of a substrate. By pre-placing or synchronously adding self-fusing alloy powders with specific components, such as nickel-based, cobalt-based, and iron-based alloys, etc., they are evenly spread on the surface layer of the part in a molten state and reach a predetermined thickness, forming a good metallurgical bond with the micro-melted substrate metal material, and there is only a very small dilution between them. During the subsequent solidification process, a functional cladding material layer with properties completely different from those of the substrate and with predetermined special properties is formed on the surface of the part, so that the properties of the material surface can be completely changed, and finally, the surface of the inexpensive material can obtain extremely high wear resistance, corrosion resistance, high temperature resistance, etc.

[0003] According to the patent number 201810835455.3, a laser cladding device for the inner wall of medium and small diameter pipes is disclosed, which can perform laser cladding operations on the inner wall of the pipe. However, the laser cladding head of this solution is in a fixed mode, which means that the laser beam can only perform cladding treatment on the surface of the workpiece from a single direction. In this way, the cladding layer will show an uneven distribution state, the range of the heat-affected zone is large, and the overall cladding efficiency is also difficult to be satisfactory. Therefore, we propose a rotary laser cladding head to solve the above problems. Content of the Utility Model

A rotary laser cladding head is provided.
