Description

technical field [0001] The invention relates to the technical field of powder feeding devices, in particular to a rotary disk type powder feeding device for laser processing of material addition and subtraction. Background technique [0002] Additive and subtractive composite processing technology is a technology that combines product design, software control, and additive manufacturing with subtractive manufacturing. Therefore, there are certain requirements on the market for the rotary table powder feeding device for laser processing of adding and subtracting materials; however, most of the existing powder feeding devices for laser processing of adding and subtracting materials use a scraper for feeding, and the method is relatively simple. And it is easy to cause raw material deposition and powder unevenness. Most of the existing rotary table powder feeding devices have complex structures, which are inconvenient for disassembly and maintenance, and affect the use. Theref...

Problems solved by technology

[0002] Additive and subtractive material composite processing technology is a technology that combines product design, software control, and additive manufacturing with subtractive material manufacturing. To provide raw materials, therefore, the market has certain requirements for the rotary table powder feeding device for laser processing of increasing and decreasing materials; however, most of the existing powder feeding devices for laser processing of increasing and reducing materials use scrapers for feeding, and the method is relatively simple. And it is easy to cause raw material deposition and powder unevenness. Most of the existing rotary table powder feeding devices have complex structures, which are not easy to disassemble and maintain, and affect the use. Moreover, the existing rotary table powder feeding devices have simple feeding methods and are not convenient for continuous quantitative feeding. Therefore, it is very necessary to invent a turntable powder feeding device for laser processing of increasing and decreasing materials at this stage.
