Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying equipment, in particular to a vibration type powder conveying device. Background Art

[0002] As a metal surface modification process, laser cladding technology can achieve corrosion resistance and wear resistance modification of metal surfaces. The core element of the laser cladding technology modification process is the filler used in the process - alloy powder. The performance of the alloy powder determines the performance of the metal after cladding. Alloy powder is different from traditional solder. Traditional solder is mainly welding rods and welding wires. During the welding process, the solder and the molten pool can be butt-welded at any angle. However, due to its own physical properties, alloy powder is in powder form and has a certain fluidity. Therefore, in the laser cladding process, it is necessary to focus on the powder feeding effect to achieve smooth powder feeding to ensure the cladding effect.

[0003] In the prior art, the consumables for laser cladding are alloy powders, which are generally fine particles of 120-270 mesh. Therefore, when the powder flows freely in the powder tube, powder accumulation, uneven powder discharge, sticking to the inner wall of the powder feeding tube, and even powder blockage are prone to occur. The usual solution to this problem is to knock the powder tube with an object and blow the powder tube with compressed air to clear it so that the accumulated powder in the powder tube flows out of the powder tube, which is very inconvenient to use and difficult to control the powder discharge, making it inconvenient to use.
