METHOD FOR MOLDING SPHERICAL STORAGE CONTAINER USING ALUMINUM THICK PLATE

WIPO Patent Application WO/2013/191323

A1

The present invention relates to a method for molding a spherical storage container using an aluminum thick plate and, more specifically, to a method for molding a spherical storage container using an aluminum thick plate, in which an inside curvature has a target curvature. The method for molding a spherical storage container using an aluminum thick plate, according to the present invention, is a method for molding a storage container which is formed as a spherical shape by allowing a plurality of plates mainly made of aluminum to be bonded, and the method for molding the spherical storage container comprises: the first step of positioning the plates on a die which is formed by allowing a surface thereof that supports the plates to have a target curvature; the second step of pressing the plates by moving a punch which is formed by allowing a surface thereof that faces the plates to have a larger curvature than the target curvature; and moving the punch to the original position. Thus, according to the present invention, since the inside curvature of the storage container is formed to have the target curvature, an elastic restoring force is reduced such that a degree of precision in measurement can be improved, and it is possible to determine an exact storage capacity and to load a desired capacity.
