Abstract
An additive manufacturing device for an aerospace truss includes a raw material input unit, a longitudinal beam forming unit, a longitudinal beam traction unit, a cross beam forming unit and a truss support unit. The raw material input unit stores pre-impregnated wires and pre-impregnated tapes, and a motor drives rollers to convey the pre-impregnated wires and the pre-impregnated tapes forward; the longitudinal beam forming unit is composed of three sets of forming molds, and the pre-impregnated tapes form V-shaped longitudinal beams through heating molds; a stepper motor used in the longitudinal beam traction unit drives three sets of roller traction devices through steering gears to pull formed longitudinal beams; the cross beam forming unit is composed of a motion module and a printing module, and a truss cross beam is printed through aD printing method of molten deposition.
