Abstract
PURPOSE: To simply form an expanded socket with high precision by moving an outer split mold being preassembled at the part of a blank tube for insertion along the blank tube insertion direction and at the same time, increasing the thickness of the tube by pressure-insertion.
CONSTITUTION: An outer mold 11 is constituted as a split mold and individual outer molds 11 are fixed on a tip of a thrust axis 12 respectively. The inner surface of the outer mold 11 is composed of a nonexpanded part forming surface 13, expanded part forming surface 14 corresponding to the part 6 to be expanded, and an inclined surface 15 to communicate said parts in continuation and also to form an inclined surface 2c. The outer molds 11 is arranged at a waiting position 11b, and when a blank tube 1a is completely inserted into a core mold 4, the outer molds 11 are moved collectively in an arrow direction A and then the outer molds are joined each other to constitute a forming mold. Next, said forming mold is moved into a forming position as shown by an arrow B to form the external circumference of the expanded socket. At the same time, the blank tube 1a is further moved by pressing into an arrow direction C to form a socket while increasing its thickness.
