Document Type and Number:
WIPO Patent Application WO/2024/087420
Kind Code:
A1
Abstract:
Disclosed in the present invention is a truss additive manufacturing device for aerospace. The whole device comprises five units: a raw material input unit, a longitudinal beam forming unit, a longitudinal beam traction unit, a transverse beam forming unit and a truss support unit, wherein the raw material input unit stores prepreg wires and prepreg tapes; rollers are driven by means of an electric motor to transmit the prepreg wires and the prepreg tapes forwards; the longitudinal beam forming unit consists of three sets of forming dies; V-shaped longitudinal beams are formed on the prepreg tapes by means of heating dies; the longitudinal beam traction unit uses a stepping motor to drive three sets of roller traction devices by means of a steering gear to pull the formed longitudinal beams; the transverse beam forming unit consists of a motion module and a printing module; and truss transverse beams are printed by means of fused deposition 3D printing.
