Embodiment Construction

[0012] In FIG. 1 , the control motor 2 in the scraper powder feeder 1 drives the turntable 6 to rotate, so that the powder in the powder storage funnel 3 flows continuously onto the turntable 6 through the nozzle 5 . When the plane turntable loaded with powder turns to the scraper 4, the powder synchronously moving with the plane turntable 6 is blocked and accumulates at the scraper, and when the amount of accumulation reaches a certain level, it continues to fall into the funnel 7 along the edge of the plane turntable , and form a powder flow. The powder falling into the funnel is sent into the laser action area through the conveying pipeline 12 under the action of gravity and auxiliary gas. In the present invention, the measuring pipeline 13 is installed between the outlet of the funnel 7 and the inlet of the delivery pipeline 12 (it can also be installed between the two sections of the delivery pipeline), and the weighing pressure sensor 8 (also can be a micro pressure sens...

Abstract

An autoamtic controller for laser coating and powder-feeding system is composed of measuring pipe communicated with power-delivering pipeline, sensor, and data acquiring and processing system connected with the control motor of powder feeder and composed of amplifier, A/D converter and data processor. It can perform real-time monitor and regulation of feeded powder.

Description

technical field [0001] The invention belongs to the technical field of laser material processing, in particular, it relates to an automatic control device for laser cladding powder feeding system, the automatic control device is especially suitable for self-weight laser cladding powder feeding device and positive pressure laser Cladding powder feeding device. Background technique [0002] Laser cladding refers to a surface coating method that adds metal elements or alloys to change the microscopic composition and composition of the surface layer of the material while melting the local surface of the material with a high-energy laser beam. It can not only greatly improve the strength of the material surface, but also can be used to quickly and directly manufacture metal parts. There are two main types of existing laser melting technology: pre-coating method and synchronous feeding method. Among them, the synchronous powder feeding method refers to the process of feeding the ...
