Embodiment Construction
[0018] The technical solutions in the embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0019] A device for manufacturing spherical gas cylinders, including a spinning machine, and also includes a fixed mold 1 and a positioning tool 2,
[0020] The fixed mold 1 is provided with a concave hemispherical inner cavity, and the radius of the inner cavity is consistent with the outer diameter of the spherical gas cylinder, so as to ensure that the bottom of the spinning blank 5 completely fits the inner cavity of the fixed mold 1, which is beneficial for the fixed mold 1 to undertake spinning. The bottom of the blank 5 and the fixed spinning blank 5 .
[0021] The positioning tool 2 is cylindrical, and the outer diameter of the cylinder is consistent with the inner diameter of the mouth of the spherical gas cylinder, so that the positioning tool 2 can be easily taken out from the closed spherical gas cylinder, ...

The invention belongs to the field of metal forming and particularly relates to a spherical gas bottle manufacturing method and device. The method is characterized by including steps: adopting a fixing mould and a positioning fixture for fixing a thin-walled cylindrical spinning blank with a semispherical bottom to a spinning machine; processing portions, except for the bottom, of the spinning blank into semispherical through a heating and spinning process; forming an intact spherical gas bottle along with the semispherical bottom. By adoption of the technical scheme, a thin-walled plate can be processed into an integral spherical gas bottle by means of spinning, and the problem of welds in use of a semispherical welding mode for traditional spherical gas bottle manufacturing is solved. The spherical gas bottle manufactured according to the method is high in pressure bearing capacity. Compared with a process for manufacturing the spherical gas bottle through thick blank forging or extruding in the prior art, the thin-walled plate spinning forming method has advantages that the material utilization rate is increased, and manufacturing cost is reduced; in addition, due to integral forming, welds are avoided, high reliability in container utilization, short manufacturing period and low manufacturing cost are realized.
Description
technical field [0001] The invention belongs to the field of metal forming, and in particular relates to a method for manufacturing a spherical gas bottle and a device thereof. Background technique [0002] Spherical gas cylinders are pressure vessels and are widely used in the military industry and civilian products. At present, the manufacturing method of spherical gas cylinders is usually to forge or extrude a thick-walled blank with metal raw materials, and to form a hemisphere through internal and external machining, and then weld two hemispheres together to form a complete spherical gas cylinder. This traditional manufacturing method has the following disadvantages: there is a weld seam, and the strength of the weld seam can reach 90% compared with the spherical vessel body, and the weld seam seriously weakens the pressure bearing capacity of the spherical pressure vessel; waste of material, forging or extrusion During the process, the utilization rate of materials is...
