Problems solved by technology

However, during laser cladding, the existing nozzle has only one powder inlet channel, that is, it can only accommodate a single type of powder filling at the same time during processing, which is not conducive to changing the powder during the cladding process, that is, changing different particle sizes Therefore, it is necessary to develop a laser cladding head that can replace and fill powder at any time during the cladding process.

example 2

[0032] Such as Figure 4 As shown, the difference between this specific embodiment and Example 2 is that a drainage chamber 103 is arranged in the side wall of the upper end of the nozzle body 1, the powder filling groove 102 is arranged in the outer wall of the drainage chamber of the nozzle body 1, and the shielding ring 6 Installed on the outer wall of the drainage cavity, the piston chamber is also arranged inside the outer wall of the drainage cavity, and the nozzle body 1 is also provided with a gathering channel 104 extending from the lower part of the drainage cavity to the lower end surface of the nozzle body 1, and the upper end of the gathering channel 104 is connected with The drainage channels are in the same ring shape, and the lower end of the gathering channel 104 is divided into a plurality of air outlets. The axes of all the air outlets of the gathering channel 104 intersect on the same point of the axis of the conical cavity of the nozzle body 1, which is loc...

Abstract

The invention discloses a laser cladding head, which comprises a nozzle body. The nozzle body is a hollow cylinder structure with two ends open. Cavity, the opening of the lower end of the nozzle body is smaller than the upper end, the upper end of the nozzle body is sealed with a condenser lens, the nozzle body is provided with a powder channel and a protective gas channel, and the powder channel includes a main channel and multiple channels. There are two feeding channels, and the nozzle body is provided with a switching device for switching the communication between the feeding channel and the main channel. The multiple feeding channels of the present invention can be opened independently to realize alternate filling of various powders, so that according to cladding requirements, fast switching of powder filling with different particle sizes can be realized, and non-stop powder filling and replacement can be realized. , to ensure the continuity of processing.

Description

technical field [0001] The invention relates to the technical field of laser cladding, in particular to a laser cladding head. Background technique [0002] Laser cladding technology refers to the use of high-energy laser beams to melt the added materials on the surface of the substrate to form a high-performance cladding layer that is metallurgically bonded to the substrate. The cost of laser cladding complete sets of equipment is expensive, and the cost of cladding materials has become an important issue to be considered. The preparation of cheap and high-quality cladding layers has become the key to the wide application of this technology. The price advantage of Fe-based cladding powder is obvious, but its corrosion resistance needs to be improved. VC reinforced Fe-based composite laser cladding layer has better wear resistance, but its corrosion resistance is relatively poor. The corrosion potential of the Fe matrix can be increased by alloying, but this increases the ...
