Three-dimensional forming method of missile-borne cable network

The invention relates to a three-dimensional forming method of a missile-borne cable network. The method comprises the following steps that S1, physical manufacturing of a cabin-structure-imitated three-dimensional wiring device is carried out; S2, the length of a wire is determined according to the trend of wire ducts on the cabin-structure-imitated three-dimensional wiring device, and the wire is cut; S3, a hot melt adhesive sleeve is additionally arranged in the wire duct at the wire harness bent portion; S4, a connector corresponding to an initial end wire is brazed; S5, a wire binding frame is mounted at the position of a 90-degree outlet wire of the connector to fix the shape of a wire harness; S6, the trend of the wire of the connector is arranged according to the connection relation of the cable network; S7, wiring pre-forming is carried out on the wire on the cabin-structure-imitated three-dimensional wiring device according to a trend mark; S8, the wire harness is bound by using a polytetrafluoroeth
