| description | The invention provides a manufacturing method of a steel shell space non-developable curved surface decorative plate unit. Comprising the following steps. Unfolding after three-dimensional modeling and subdividing curved surface expansion drawing-reserving process quantity numerical control accurate cutting blanking-laser scribing-machining V-shaped grooves and bending according to lines-detecting curved surfaces by using arc surface detection sample plates and angle sample plates and correcting by using flames-designing plate unit jig frames-finely adjusting by using process partition plates and balancing weights-assembling reinforcing ribs and adjacent plates and pre-assembling the units. The special plate unit jig frame, the inner supporting process partition plate, the balancing weight, the special arc surface detection sample plate and the angle sample plate are arranged, and the V-shaped groove is formed, so that the manufacturing efficiency is improved, the linear precision of the space non-developable |
