Abstract

The invention provides a powder matching dynamic powder feeding device for large complex gradient functional component direct laser fabrication and machining equipment and belongs to the field of direct laser fabrication. The powder feeding device comprises a ratio controllable powder feeding device body, a multi-component powder pre-mixing device body and a double-screw component fine mixing device body. The ratio controllable powder feeding device body comprises a powder conveyor and a powder feeding controller which are mutually matched, the powder feeding controller is constructed to receive powder output by the powder conveyor and release the powder received from the powder conveyor in a quantity controllable mode, and the multi-component powder pre-mixing device body is constructed to receive and pre-mix the powder output by the powder feeding controller and output pre-mixed powder materials. The double-screw component fine mixing device body is constructed to receive and finelymix the pre-mixed powder materials. Through the powder-feeding device, powder raw materials can be adjusted and conveyed according to the requirement so that the multi-component raw materials can be better applied to direct laser fabrication.

Description

technical field [0001] The invention relates to the field of laser direct manufacturing, in particular to a powder proportioning dynamic powder feeding device and processing equipment for direct laser manufacturing of large complex gradient functional components. Background technique [0002] Large-scale and complex structural gradient functional parts based on gradient function have the remarkable characteristics of continuous change in internal components, structure and physical properties and disappearance of bonding interface. Functional structural parts developed for work. It is widely used in modern aviation, aerospace, deep sea exploration and other fields. [0003] There are three main methods of preparing gradient functional structural parts: (1) Gradient functional coating type, that is, a coating with a gradient composition is formed on the base material, which is mainly used for the preparation of gradient functional coatings on the surface of structural parts. ...
