Problems solved by technology

Since the powder itself will fall down due to gravity, the prefabricated powder feeder cannot clad the substrate facade
The synchronous powder feeder directly sprays the powder to the molten pool through air pressure during cladding, so it can realize vertical processing; but it uses air pressure to spray, and the spraying place is not concentrated, which will cause a lot of waste of cladding powder. If only Process the base material plane, and use the synchronous powder feeder to feed the powder, which makes the cladding cost higher

Embodiment 1

[0021] Such as figure 1 As shown, the screw type multifunctional powder feeder includes a storage bin 1 and a casing 3 for storing cladding powder 2 .

[0022] The storage bin 1 is arranged above the casing 3 . A conveying channel is arranged axially inside the shell 3, and the conveying channel communicates with the storage bin 1, so that the cladding powder 2 loaded in the storage bin 1 can enter into the conveying channel. A screw 7 is arranged axially in the conveying channel, and one end of the screw 7 is sequentially connected to the reducer 5 and the speed-regulating motor 4 arranged on the outer side of the casing 3 .

[0023] In order to facilitate the replacement, maintenance and installation of the screw rod 7, a sealing plate 10 is provided on one side of the housing 3. When the sealing plate 10 is opened, the conveying channel is communicated with the outside world. When the sealing plate 10 is closed, the conveying channel is not communicated with the outside wo...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the powder material outlet funnel 9 is integrally formed with the casing 3 .

Abstract

The invention discloses a screw multifunctional powder feeder for solving the problems in the prior art. The screw multifunctional powder feeder comprises an outer shell and a storage bin hopper arranged on the outer shell. A conveying channel is formed in the outer shell. A screw is arranged in the conveying channel. A power device is connected with one end of the screw. The conveying channel further communicates with a powder outlet. A cleaning powder pressure inlet communicating with the conveying channel is formed in the outer shell. A synchronous powder feeding pressure inlet communicating with the powder outlet is further formed in the outer shell. The cleaning powder pressure inlet and the synchronous powder feeding pressure inlet communicate with an inert gas storage device throughgas pipes. Valves are arranged on the gas pipes correspondingly.

Description

technical field [0001] The invention belongs to the technical field of laser repair, and in particular relates to a powder feeder capable of simultaneously realizing synchronous powder feeding and preset powder feeding. Background technique [0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It adds cladding powder on the surface of the substrate and uses a high-energy-density laser beam to fuse it with the thin layer on the surface of the substrate to form a metallurgically bonded cladding layer on the surface of the substrate. In the laser cladding process, it is necessary to use a powder feeder to transport the cladding powder. [0003] Powder feeders are divided into prefabricated powder feeders and synchronous powder feeders. Since the powder itself will fall down due to gravity, the prefabricated powder feeder cannot clad the substrate facade. The synchronous powder feeder directly sprays the powder to t...
