Wire filling machining device for rapidly forming electron beam

Abstract

The invention provides a wire filling machining device for rapidly forming an electron beam. The device is characterized in that a multi-shaft worktable (4) is arranged inside a vacuum chamber (3); an electron gun (10) is mounted at the top of the vacuum chamber (3) and is connected with a high-voltage power supply (1) through a high-voltage cable (11); one or two wire feeding system vacuum chambers (8) are arranged at the outer part of the vacuum chamber (3); the wire feeding system vacuum chambers (8) are connected with the vacuum chamber (3) through a valve (12); each wire feeding system vacuum chamber (8) is internally provided with a wire feeding system (7) and a three-dimensional alignment mechanism (9); each three-dimensional alignment mechanism (9) is provided with two stations including a wire feeding station and a wire changing station; each three-dimensional alignment mechanism (9) can move between the two stations and is driven by a motor; when each three-dimensional alignment mechanism (9) is at the wire changing station, each three-dimensional alignment mechanism (9) is located in each wire feeding system vacuum chamber (8); and the valve (12) can be closed to separate the wire feeding system vacuum chambers (8) with the vacuum chamber (3). The wire filling machining device for rapidly forming the electron beam, disclosed by the invention, overcomes the defects that a wire feeding mechanism and parts in the conventional device are located in a same vacuum chamber all the time and the wire changing time is too long can be overcome.

Description

technical field [0001] The invention relates to an electron beam rapid forming wire filling processing device, which belongs to the technical field of electron beam rapid forming processing. Background technique [0002] Electron beam wire filling processing includes electron beam wire filling welding, surfacing welding, surface cladding, rapid prototyping, etc. [0003] Electron beam fused filament deposition rapid manufacturing technology is a new manufacturing technology produced by combining electron beam filament filling processing technology and rapid prototyping thought. [0004] There are two installation methods for the electron gun of the existing electron beam rapid prototyping device in the world, one is fixed outside the vacuum chamber, and the other is installed on the motion mechanism in the vacuum chamber. [0005] In 2007, NASA Langley Research Center obtained the US patent (US7,168,935 B1), which is characterized by: a vacuum chamber, the electron gun is f...
