With the continuous development of clean energy, the application of the hydrogen fuel cell in the vehicle-mounted field is more and more extensive. A hydrogen fuel cell is a power generation device that directly converts chemical energy of hydrogen and oxygen into electrical energy. The basic principle is that hydrogen and oxygen are supplied to the anode and the cathode, respectively, and after the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are emitted to the cathode through an external load. Thereby generating a current in the external circuit. Oxygen can be obtained from air, but hydrogen needs to be stored by pressure vessels. Therefore, the volume, the high pressure resistance strength, the self weight and other parameters of the pressure container are directly related to the endurance capacity of the fuel cell, and the endurance capacity of the fuel cell can be effectively improved by the large volume, the high pressure resistance and the light weight of the pressure container.
The inner container of the pressure container is usually thinned by adopting powerful spinning so as to accurately control the wall thickness of the inner container and achieve the aim of light weight. The traditional powerful spinning method is that the inner container is spun to the required wall thickness through the matching of the spinning wheel and the mandrel, and in the traditional powerful spinning process, a blank must be fixed by the bottom of the blank, so that the cost and the process of the powerful spinning thinning of the inner container of the pressure container are increased, and the powerful spinning thinning efficiency of the inner container of the pressure container is reduced; in addition, the length of the mandrel in the powerful spinning thinning directly determines the maximum length of the inner container of the pressure container to be processed, and the length and the size of the inner container of the pressure container are limited.
