  • Metal additive manufacturing extrusion mechanism for monitoring and improving mechanical properties in situ
    Patent number: 11845126
    Abstract: The present disclosure relates to a metal additive manufacturing extrusion mechanism for monitoring and improving mechanical properties in situ, and belongs to the technical field of metal additive manufacturing. The mechanism comprises a wire conveying unit, a composite cavity unit, a high-temperature loading unit, a temperature detecting unit, a pressure loading unit, a pressure detecting unit and an in-situ monitoring unit. Multi-stage high-temperature loading is achieved through silicon nitride heater components distributed in the piston, the outer wall of the cavity and the nozzle, and meanwhile service temperature detection is achieved through thermocouple components. Multi-stage pressurization is achieved through continuous pressure loading of the wire conveying mechanism and high-frequency pressure loading of the piston mechanism and the four-rod mechanism, and then service pressure detection is achieved through strain gauge components on the top of the piston and the inner wall of the cavity.
