Manufacturing method of bent and twisted parallelogram box type component

The invention belongs to the field of building steel structure manufacturing processes, and particularly relates to a manufacturing method of a bent and twisted parallelogram box type component. Firstly, an upper wing plate, a lower wing plate, a left web plate and a right web plate in a component are integrally unfolded in a Tekla model, bending lines and bending angles are determined to be used for bending the bent wing web plates, and component three-dimensional coordinate positioning points are created to be used for placing a jig frame. According to the manufacturing method of the bent and twisted parallelogram box type component, a Tekla model is used for unfolding a wing web part, a numerical control cutting machine is adopted for blanking, the part size precision is high, and the blanking quality is good; the groove is machined before the wing web is bent, and compared with the machining quality after bending, the machining quality is good, the efficiency is high, and the assembly precision is high; t
