Abstract

PURPOSE: To expand the elastic bag for carrying out the forming work, on purpose to contrive the simplification of construction and reduction of forming cost, by moving and retaining the forming dies in the cubic space within the base frame provided with the diaphragm.
CONSTITUTION: The segments 16, 17, of the forming dies 12 are opened by the cylinder 3, and the preliminarily formed work W is set to the blank holders 14, 15, of the base 13, and then, the die segments 16, 17, are colsed by the cylinder 3. Next, the forming dies 12 is moved into the base frame 7 by the cylinder 22 and are set; after that, the pressure liquid is introduced into the diaphragm 11 in order to press and retain the upper surface and the left and right side surfaces of the forming dies 12. Then, the pressure liquid is introduced into the pressure bag 19, so as to expand the work W and thrust it against the the inner walls 16b, 17b; hereby, the forming work is carried out. After releasing the diaphragm 11 and the pressure bag 19 from the liqued pressure, the forming dies 12 are sent out of the base brame 7 by the cylinder 22, and the forming dies 12 are opened by the cylinder 3, for disharging the formed product.
