Problems solved by technology

In the process of gravity powder feeding, because the gravity potential energy of the alloy powder itself is converted into kinetic energy, the alloy powder reaching the processing position is often in a spray state, which seriously reduces the utilization rate, increases the production cost, and affects the surface smoothness of the cladding layer.

Embodiment 1

[0032] Such as figure 1 As shown, a powder feeding device includes a buffer part 1 and a buffer part 2 movably connected by a fastener 3, which is convenient for adjusting the angle between the buffer part 1 and the buffer part 2, and then flexibly adjusts powder feeding angle, and each component is easy to disassemble and maintain, which improves work efficiency, especially the powder feeding nozzle 5 is a consumable item in actual production. When the powder feeding nozzle 5 is damaged, all parts only need to be disassembled, Only the powder feeding nozzle 5 needs to be replaced to reduce the cost input.

[0033] Such as Figure 1-3 As shown, the buffer component 1 includes a powder feeding pipe 4 and a rotating head 9, the rotating head 9 is arranged at the end of the powder feeding pipe 4, and the alloy powder reaches the rotating head 9 from the powder feeding pipe 4, and the The inside of the rotating head 9 is provided with a curve 11, the angle of the curve 11 is set...

Embodiment 2

[0036] Such as image 3 As shown, the intersection of the upper regulating plate 6 and the lower regulating plate 7 is provided with a powder outlet 10, and the inclination direction of the curve 11 is opposite to the direction of the powder outlet 10, and the alloy powder reaches the powder feeding nozzle 5 Inside, it is conveyed to the powder outlet 10, the conveying direction is changed, the second buffering effect is completed, and it is discharged through the powder outlet 10.

[0037] The powder outlet 10 is set as a slope structure 13, and the angle between the slope structure 13 and the horizontal plane is set to 25-30°. Under the joint action of the slope structure 13 and the upper regulating plate 6, the alloy powder is formed Again buffering effect, high uniformity of powder feeding, high utilization rate of alloy powder, effectively improving the surface smoothness of cladding layer.

[0038] Such as figure 1 , Figure 4 As shown, the insides of the upper adjust...

Embodiment 3

[0041] Such as Figure 1-4 As shown, using the powder feeding device, the specific work includes the following steps:

[0042] (1) By adjusting the fastener one 3, adjust the angle between the buffer part one 1 and the buffer part two 2, so that the angle between the powder feeding nozzle 5 and the vertical direction is 40-70° to achieve uniform feeding The purpose of powder;

[0043] (2) The alloy powder slides down from the powder feeding pipe 4, reaches the rotating head 9, and realizes the first buffering effect in the curve 11, changes the conveying direction, and reduces the conveying speed;

[0044] (3) The alloy powder arrives in the powder delivery nozzle 5 from the rotating head 9, and is transported to the powder outlet 10 to realize the second buffering effect, change the transport direction, and reduce the transport speed;

[0045] (4) Slide the upper adjusting plate 6 and the lower adjusting plate 7 along the powder feeding nozzle 5 to change the size and powde...

Abstract

The invention relates to a powder feeding device and an application method thereof, and belongs to the technical field of laser cladding equipment. The powder feeding device comprises a first buffering component and a second buffering component which are movably connected through a first fastener. The first buffering component comprises a powder feeding pipe and a rotating head, wherein the rotating head is arranged at the tail end of the powder feeding pipe, and a curve is arranged inside the rotating head. The second buffering component comprises a powder feeding nozzle and an adjusting plate. The adjusting plate is arranged on the surface of the powder feeding nozzle. The powder feeding device has the beneficial effects that the powder feeding angle and height are flexile and adjustable, powder feeding is even, and the alloy powder utilization rate is high; and the surface flatness of a cladding layer is effectively improved, dismounting and maintaining are convenient, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of laser cladding equipment, and in particular relates to a powder feeding device and an application method thereof. Background technique [0002] Laser cladding refers to placing the selected coating material on the surface of the substrate to be clad by different powder feeding methods, melting it and the thin layer of the substrate surface at the same time through laser irradiation, and rapidly solidifying to form a very low dilution, which is compatible with the substrate. Metallurgically bonded surface coating, a process method that significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface, so as to achieve the purpose of surface modification or repair, which not only meets the specific performance requirements of the material surface Requirements, but also save a lot of precious elements. [0003] At prese...
