Abstract

PURPOSE: To easily form an intricate bulging shape by disposing two pieces of continuous cylinders at the end of a cylindrical member, and arbitrarily controlling the axial load of pressure medium and cylindrical member in a rubber bulging device.
CONSTITUTION: A guide rod 22, a pressure medium 23, auxiliary sealings 25, 25', and sealings 24, 24' are loaded in a cylindrical member 21. Next, the member 21 is grasped freely slidably by an upper die 26 and a lower die 27. Axial load adding rods 30, 30' are touched to both ends of the member 21 by pressing cylinders 33, 33', and internal pressure applying rods 31, 31' are inserted into the guide rod 22. Thence, the cylinders 33, 33' and the cylinders 32, 32' are advanced in the direction of the member 21, and the medium 23 is axially compressed from both ends by the rods 31, 31' to apply internal pressure to the inside of the member 21; at the same time, axial load is applied to the member 21 by the rods 30, 30' to force the same axially, thereby bulging the inflating part while supplying the blank material. The member 21 is stuck closely to the bulged part 25, and is thereby bulged.
