Manner null of the compact fetch in dry type gravitational pressure pressurization

摘要

PROBLEM TO BE SOLVED: To efficiently and in-expensively improve a CIP formed with a simple device by drawing out a mandrel from a formed body together with a bottom punch and taking out the formed body while holding the external circumference face of the forming body as holding the forming body vertically. ;SOLUTION: A bottom punch 9 is drawn downward from the lower end of a pressure vessel 2 together with a mandrel 3 followed with a formed body 12, and it is arranged at the position so that the upper end part of the formed body 12 is made lower than the lower end of the pressure vessel 2 (a). A formed body circumferential face holding means 21 fixed on a supporting body 29 through an air cylinder is absorbed on the external circumferential face of the formed body 12 (b). The bottom punch 9 is moved downward and an internal 30 requiring for a supporting part 16 to insert between an opening end face of the formed body 12 and the upper face of the bottom punch is installed. An opening end face supporting means 15 is moved toward the formed body 12 and inserted in the interval 30 (c). By moving the bottom punch 9 downward to the position so that the upper end part of the mandrel 3 is made lower than the lower end of the opening end face supporting means 15, the formed body 12 is drawn out from the mandrel 3.;COPYRIGHT: (C)1997,JPO
