Embodiment 1

[0041] Such as figure 1 As shown, a powder feeding device includes a fixed part 1 and a powder feeding nozzle 4, an adjustment device is provided between the fixed part 1 and the powder feeding nozzle 4, and the adjustment device includes a horizontal adjustment part 2 and a vertical adjustment part 3 , the vertical adjustment part 3 is located inside the horizontal adjustment part 2, through the synergistic effect of the horizontal adjustment part 2 and the vertical adjustment part 3, the distance between the powder outlet 201 and the surface of the substrate is adjusted, which has high flexibility and contributes to To improve the quality of cladding, the powder feeding device is connected with the laser.

[0042] Such as Figure 1-2 As shown, the horizontal adjustment part 2 includes an adjustment plate 5 and an adjustment piece 6, the adjustment plate 5 is set as a concave structure, the middle part is provided with a through hole 16, and its frame is provided with an adj...

Embodiment 2

[0048] Such as figure 1 , figure 2 , Figure 5 with Image 6 As shown, the powder feeding nozzle 4 is arranged in a conical structure, and a laser channel 14 is arranged inside the conical structure, and at least two powder feeding channels 20 are uniformly arranged on the conical wall of the conical structure. A powder outlet 201 is provided at the bottom of the powder feeding channel 20, the powder feeding channel 20 is connected to the powder feeding pipe 11, and the included angle between the central axis of the powder feeding channel 20 and the central axis of the laser channel 14 is 15-25° , as a preference, the included angle is 15°, 20°, 25°, which can not only ensure a certain distance between the powder feeding channel 20 and the laser channel 14, reduce the probability of the powder feeding tube 11 being burned out, but also ensure that The laser focus and cladding powder converge at one point, which improves the effective utilization rate and cladding quality o...

Embodiment 3

[0051] Such as Figure 1-7 As shown, the specific use of the powder feeding device includes the following steps:

[0052] (1) Synchronously adjust the adjustment member-6 on the opposite frame of the adjustment plate 5, wherein one adjustment member-6 performs a loosening operation, and the other one opposite to it performs a tightening operation, driving the adjustment cylinder 7 in the hollow structure 91 internal movement in all directions;

[0053] (2) After the center of the protective lens 10 coincides with the center of the through hole 16, stop adjusting the adjusting part 16 to ensure that the laser focus and the cladding powder converge at one point, and improve the effective utilization rate and cladding powder of the cladding powder. quality;

[0054] (3) Loosen the adjusting part 2 15, impel the adjusting part 2 15 to slide up and down along the slideway 81, and change the distance between the powder outlet 201 and the surface of the substrate;

[0055] (4) Whe...

Abstract

The invention relates to a powder feeding device and a using method thereof and belongs to the technical field of laser cladding. The powder feeding device comprises a fixing part and a powder feeding nozzle, wherein a regulation device is arranged between the fixing part and the powder feeding nozzle and is composed of a horizontal regulation part and a vertical regulation part; and the vertical regulation part is arranged in the horizontal regulation part. The powder feeding device is capable of regulating the distance between a powder outlet and the surface of a substrate, has the characteristics of high regulation accuracy, convenience and rapidness in operation, strong practicability and high economic benefit and is beneficial to improving the effective availability of cladding powder and the cladding quality.

Description

technical field [0001] The invention belongs to the technical field of laser cladding, and in particular relates to a powder feeding device and an application method thereof. Background technique [0002] Laser cladding technology is a new surface modification technology. By adding cladding materials on the surface of the substrate and using a high-energy-density laser beam to melt it together with the thin layer on the surface of the substrate, the surface of the base layer is formed on the surface of the substrate. It is a cladding layer combined with metallurgy, which can significantly improve the wear resistance, corrosion resistance, heat resistance and oxidation resistance of the base layer surface. [0003] Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of small dilution, dense structure, good combination of coating and substrate, many materials suitable for cladding, and large changes in particle size an...
