Abstract

The invention relates to an electron beam fuse additive manufacturing equipment with coaxial filaments. The equipment includes a control system and an annular beam spot cold cathode electron gun electrically connected to it, a wire feeding system, a high-voltage accelerating power supply, a beam current control system, an air flow control system, a cooling system, a focus control circuit, a wire end position detection system, and a vacuum chamber. and a three-dimensional motion mechanism located in a vacuum chamber. The control system is based on PLC and CNC. The electron gun includes an upper annular cathode, a lower tapered anode and a guide wire tube that axially passes through the cathode and anode. The cathode is connected to a high-voltage acceleration power supply and Cooling system, the lower tapered outlet end of the anode is connected to the vacuum chamber, the three-dimensional motion mechanism is used to drive the worktable to move in the three-dimensional direction, the control system controls the wire feeding system to pass the metal wire through the wire guide tube from the cathode inlet end to the anode outlet end It is shown that the control system controls the beam current control system, the air flow control system, the focus control circuit and the wire end position detection system.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an electron beam fuse additive manufacturing equipment with coaxial filaments. Background technique [0002] Electron beam fuse additive manufacturing technology has been developed for many years, and its technology is becoming more and more mature. The existing electron beam fused wire additive manufacturing technology can define the fused wire additive manufacturing technology of hot cathode electron gun shaft side feeding according to the characteristics of the beam source and the wire feeding method. Compared with other 3D printing technologies, the advantages of electron beam fused filament additive manufacturing technology are reflected in the high-quality, efficient and rapid manufacturing of large metal components. [0003] At present, the electron beam fuse additive manufacturing equipment developed by research institutions at home and abroad are all base...
