Bulging surface forming method and the three-dimensional object using the same metal plate, and the pressure vessel obtained by the production method and the method of metal container having a bulging surface
Bulging surface forming method and the three-dimensional object using the same metal plate, and the pressure vessel obtained by the production method and the method of metal container having a bulging surface
PROBLEM TO BE SOLVED: To provide a metallic container having a bulged metallic face which is costless and can be manufactured in a short time, and generates less deflection and excellent in reliability and durability, simplicity and increases versatility and enhances the degree of freedom in design.;SOLUTION: The buged face forming method of a metallic plate 1 is constituted of a process in which a continuous bead 3 having an uniform size along the edge of a metallic bead 3 and the frame base 2 formed in a specified shape is formed and welded, a process in which a fluidizable medium is supplied into a space surrounded by the metallic plate and the frame base welded in the previous process to form the bulging face by impressing a uniformly distributed load corresponding to a stress larger than the yielding stress of the metallic plate or smaller stress than the terrible strength of the metallic plate, a process in which the fluidizing medium is discharged from a space after a specified bulged face has been formed, and a process in which the metallic plate is cut and separated into specified shapes.;COPYRIGHT: (C)2002,JPO
