Abstract
PURPOSE: To mass-produce a single flower vase having a beautiful surface, by inserting core metal in the head part of metal material and forming small diameter flower vase head carrying out contraction processing and then, forming large diameter flower vase head compressing in axis direction by applying a high liquid pressure in the tube and moreover, jointing the bottom plate.
CONSTITUTION: The support cylinder 4 is inserted in the lower part of the metal material tube 1 and contraction processing of the upper part of the tube 1 is carried out by the contraction die 7A having tapered contraction part at the lower part of contraction hole, corresponding to the conical head part 5a of the core metal 5. Moreover, contraction processing is repeated in plural times by the contraction dies 7F... making contraction hole smaller successively and the head part of flower vase is formed decreasing its diameter. High liquid pressure is applied in the contraction processing tube and at the same time the lower part of the above tube is swollen by compressing in axis direction by the upper formation die 26A and the lower formation die 25A. Then, the flower vase drum part 35B increased its diameter, is formed repeating swelling processing in plural times and the single flower vase is obtained joining the bottom plate at the bottom part.
