Metal additive manufacturing device oriented to weightless flight and vacuum working conditions

Abstract

The invention discloses a metal additive manufacturing device oriented to weightless flight and vacuum working conditions. The metal additive manufacturing device comprises a vacuum system, a metal fusion system, a movement system and a monitoring system, metal wires are used as a raw preparation material, a high-energy-beam heat source is adopted as an energy source, and the device is used for metal additive precise manufacturing under weightless flight microgravity and vacuum working conditions. The design of a lightweight cavity and arrangement of the compact-type motion system are adopted,the ratio of an effective space of a molding area to the system occupation space is increased, weightless flight experiment platform mechanical and electrical constraint conditions are satisfied, andmetal additive manufacturing experiments in a weightless flight periodicity microgravity environment are carried out; an adjustable vacuum system is arranged to guarantee that the whole metal wire additive manufacturing process is carried out in a vacuum condition; the manufacturing process and state data are entirely recorded to provide a technical guarantee for the observation and traceback ofthe manufacturing process; the ring-column-type high-energy-beam heat source is adopted for focusing small-diameter light spots in cooperation with a precise wire feeding system, then it is guaranteedthat the heat source and the raw material are symmetric and concentric, and precise manufacturing is achieved.
