Problems solved by technology

This structure does not involve the powder plate structure, and the powder feeding is not accurate enough
[0007] Moreover, the sealing performance of the existing powder feeding unit is difficult to apply to high-pressure situations, and often the sealing effect cannot meet the needs of high-pressure equipment, and the equipment is difficult to meet the production process requirements
[0008] After searching, no high-pressure powder feeder unit with good airtightness suitable for spraying and laser cladding technology was found

Abstract

The invention relates to a high pressure powder feeder unit. The high pressure powder feeder unit comprises a driving unit, a powder storing unit and a powder disc unit arranged successively. An output end of the driving unit is connected to a driving shaft extending into the powder storing unit. The powder disc unit comprises an upper powder disc and a lower powder disc. The upper powder disc comprises a disc body, wherein an air inlet is formed in the center of the disc body, an air overflowing breadth is arranged along the outer edge of the air inlet, the lower powder disc is a cover body of a ring concave part structure and comprises a fixed protrusion arranged at the center, and a powder disc rotating shaft mounting hole is formed in the center of the fixed protrusion. The high pressure powder feeder unit combines the driving unit, the powder storing unit and the powder disc unit together. By improving the structures of the driving unit, the powder storing unit and the powder discunit, the whole powder feeding unit is extremely good in sealing property, is suitable for a high pressure condition and is enough to meet a production demand of production. The unit can be suitablefor being used in a condition not enough in pressure, can meet the demand of cold spraying, thermal spraying and laser cladding techniques, is wide in application and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of laser surface modification, and in particular relates to a high-pressure powder feeder unit and its application. Background technique [0002] The function of the powder feeder is to accurately feed the powder into the laser melting pool or directly spray the powder onto the surface of the substrate through the spray gun according to the requirements of the processing technology, and ensure that the powder can be conveyed continuously, uniformly and stably during the processing. According to different types of process characteristics and powder types, the types of powder feeders that have been developed at home and abroad mainly include screw type powder feeder, rotary table type powder feeder, scraper type powder feeder, capillary type powder feeder, drum type powder feeder, etc. Powder feeder, electromagnetic vibration powder feeder and boiling powder feeder. [0003] In the production of cold spraying...
