Winding method suitable for winding engine shell

The invention provides a winding method suitable for winding an engine shell. The winding method comprises the manufacturing steps that a special extension rod is designed, and the operation space of a wire nozzle in the axial direction of a workpiece is expanded; the prepreg tape winding and conveying device is provided with a special conveying roller group and a special wire nozzle heating device; and the cut prepreg tape is used for winding the engine shell. The method has the advantages that compared with a traditional winding method, namely wet winding, for winding the engine shell, the resin viscosity of the prepreg tape is high, the friction coefficient of fibers and the core mold is increased, a larger variable-angle space can be obtained when the non-isopolar hole winding engine shell is wound, a larger margin is achieved when the linear angle of the shell is designed, and the linear angle of the shell is designed. The winding of a shell with a larger aperture ratio is facilitated, the winding device
