Problems solved by technology
Among them, the common powder feeding equipment is divided into two forms: carrier gas and gravity. The former needs to rely on the gas path as the carrier. When the powder is sent out, there will be an air pressure effect, which will cause the powder to be partially scattered on the surface of the workpiece, thereby reducing the powder. Utilization
However, the powder feeding mechanism of traditional gravity powder feeding is mostly a single powder feeding, which cannot meet the technical requirements of super large powder cladding and multiple powder feeding

The present invention relates to the technical field of laser cladding, in particular to a centrifugal laser cladding powder feeding device and a laser cladding powder feeding method, comprising: a funnel with an upper opening, and a wall extending downward from the upper opening is gradually narrowed to form A lower opening; the powder feeding plate, which is in the shape of a disc, is placed horizontally in the funnel, and there is a gap between the wall of the funnel; the powder scraping plate is fitted to the powder feeding plate above; the driving part is used to drive the powder feeding disc to rotate relative to the powder scraping disc. The present invention adopts the centrifugal + gravity powder feeding method, which solves the problem of powder loss caused by carrier gas powder feeding, and greatly improves the powder utilization. Moreover, through the setting of multiple first through holes, it is equivalent to multiple powder feeding volumes of traditional powder feeders, and multiple gears can feed different powders at the same time.
Description
technical field [0001] The invention relates to the technical field of laser cladding, in particular to a centrifugal laser cladding powder feeding device and a laser cladding powder feeding method. Background technique [0002] Laser cladding technology is a kind of rapid heating and melting of metal powder and substrate surface under the action of laser beam, and forms a layer of high-performance alloy coating on the substrate surface after cooling, which can significantly improve the wear resistance and durability of the substrate surface. corrosion properties. Due to its great economic benefits, it is currently being used more and more widely in industrial production. [0003] In the process of laser cladding, the powder feeding equipment conveys the powder, and the metal powder reaches the workpiece through the nozzle on the laser head. Among them, the common powder feeding equipment is divided into two forms: carrier gas and gravity. The former needs to rely on the g...
