The rotating gear meshes with the ring-shaped fixed gear guide rail, the rotating gear is fixed on the output shaft of the servo motor, the servo motor is fixed to the shell of the funnel through the servo motor bracket, the outlet of the funnel is vertically facing the upper surface of the substrate, and the flow adjustment block The flap is arranged at the outlet position of the funnel, the flow regulating flap is fixedly mounted on the output end of the flap adjusting motor, and the shell of the flap adjusting motor is fixedly connected with the outer wall of the lower end of the funnel. The invention is used for electron beam additive manufacturing.

Description

technical field [0001] The invention relates to an electron beam fuse deposition processing technology, in particular to a pre-powder feeding type electron beam additive manufacturing device. Background technique [0002] In many fields such as aerospace, micro-nano manufacturing, and biomedical engineering, electron beam additive manufacturing technology has been widely used. At present, the commonly used electron beam additive manufacturing methods include electron beam fuse deposition and electron beam selective melting. The principle of electron beam fuse deposition is to melt the wire under the action of the heat source of the electron beam and then solidify to form a deposit. Different wire feeding directions and angles have a great influence on the shape and performance of the deposit, and the wire feeding accuracy is electronic. The key to beam fuse deposition is that once the wire material is thermally deformed or the wire feeding accuracy is affected by the outsid...
