Abstract: A device for forming a V-shaped full-composite pressure vessel includes a semi-cylinder body mold, where the length of a cylinder body part of the semi-cylinder body mold is half of the length of a cylinder body of a processed pressure vessel; a groove for placing a valve seat is reserved at one end of a dome part of the semi-cylinder body mold, and a fiber yarn-dividing ring is mounted at the other end; the semi-cylinder body mold is connected to the valve seat through a spline; and the valve seat and the fiber yarn-dividing ring are in threaded connection with a rotating shaft of fiber winding equipment. According to this disclosure, a liner-free pressure vessel can be manufactured completely by processing a composite material, so the mass of the pressure vessel can be reduced. Furthermore, the mold is not required to be dissolved and taken out.

Abstract: Carbon fiber winding equipment includes integrated spiral and hooping winding equipment for multi-bundle fibers. The equipment includes a spiral winding unit, a hoop winding unit, and a guide base and a supporting base for supporting the spiral winding unit and the hoop winding unit. An end face of a gear driving plate includes a continuous bulbous iris curve sliding rail, a sliding rod extends into the sliding rail and is capable of driving a yarn guide shaft tube to slide radially along with the rotation of the gear driving plate. A bevel gear is capable of driving the yarn guide shaft tube to do auto-rotation motion along with the rotation of a second transmission gear ring. A ratchet driving plate rotates to drive an electric telescopic rod to push a hoop rotation plate to rotate so as to drive a hoop winding bundling device to complete a hoop winding action.
