Abstract

The invention relates to electron beam coaxial wire feeding additive manufacturing equipment and method. A wire feeding straightening device is arranged above a wire feeding nozzle of the equipment, ametal wire is sent out by the wire feeding straightening device, and the metal wire is sent into the wire feeding nozzle after being guided and straightened; the wire feeding nozzle is coaxially arranged in an electron beam gun system and is arranged on an XYZ positioning device of an electron beam gun together with the electron beam gun system, the XYZ positioning device of the electron beam gunis arranged above a forming substrate, and the XYZ positioning device of the electron beam gun drives the electron beam gun system, the wire feeding nozzle and the metal wire to accurately move and position under the control of a deposition controller, so that the metal wire is melted and solidified according to set requirements; and the molten metal wire is deposited layer by layer on the forming substrate which is rotatable along a vertical axis and tiltable along a horizontal axis under control by the deposition controller, and a part in a desired shape and structure is formed. The equipment and the method provided by the invention have high printing efficiency and high precision, and can realize the additive manufacturing of metal structural members.

Description

technical field [0001] The invention relates to a metal 3D printing device, in particular to a metal 3D printing device using electron beams. Background technique [0002] Additive manufacturing, commonly known as 3D printing, is a combination of computer-aided design, material processing and forming technology, based on digital model files, through software and numerical control system, special metal materials, non-metal materials and medical biological materials, according to extrusion, Sintering, melting, light curing, spraying, etc. are accumulated layer by layer to create a manufacturing technology for physical objects. [0003] At present, the main metal 3D printing processes that can be used to directly manufacture metal functional parts include: Selective Laser Sintering (Selective Laser Sintering, SLS) technology, Direct Metal Laser Sintering (Direct Metal Laser Sintering, DMLS), Selective Laser Melting (Selective Laser Sintering) Melting, SLM) technology, Laser En...
