Description

Technical Field

[0001] The invention relates to the technical field of powder feeders, and in particular to a composite powder laser cladding proportioning powder feeder. Background Art

[0002] Feeder refers to a machine used to transport materials, which is commonly used in the automated, CNC and precise transportation of granular materials, powder materials, sheet materials, strip materials, etc. Laser cladding is a method of adding cladding material to the surface of the substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate to form a metallurgically bonded added cladding layer on the surface of the base. The composite powder is passed through the powder feeder to perform laser cladding operations on the parts.

[0003] Since the feeding of the feeder focuses on the control of the feeding speed, it lacks the control of the feeding accuracy. Even for the feeding speed, the adjustment node is too far from the nozzle, and the speed control itself has a relatively large cumulative error due to the existence of many subsequent links. For example, the Chinese invention patent with patent publication number CN111424277A solves the problem that the feeding focuses on the control of the feeding speed but lacks the control of the feeding accuracy.
