Abstract

The invention provides a powder-feeding type electronic beam additive manufacturing device arranged in front. The problem that an existing electronic beam selective melting additive manufacturing device is only suitable for additive manufacturing of small precise parts and thus the utilization rate of powder is very low is solved. The powder-feeding type electronic beam additive manufacturing device arranged in front comprises a hopper, an electronic gun, an annular fixing gear guiding rail, a rotating gear, a servo motor, a servo motor support, a sedimentary body, a flow adjusting stop pieceand a stop piece adjusting motor. The annular fixing gear guiding rail is fixedly mounted on a shell of the electronic gun, the rotating gear is engaged with the annular fixing gear guiding rail and fixedly mounted at an output shaft of the servo motor, and the servo motor is fixedly connected with a shell of the hopper through the servo motor support. An outlet of the hopper is perpendicular to the upper surface of a base plate directly facing the outlet, the flow adjusting stop piece is arranged at the outlet of the hopper and fixedly mounted at the output end of the stop piece adjusting motor, and a shell of the stop piece adjusting motor is fixedly connected with the outer wall of the lower end of the hopper. The powder-feeding type electronic beam additive manufacturing device arranged in front is used for electronic 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...
