Abstract: PURPOSE:To improve a forming accuracy by applying a pressure on the outer peripheral face of a die via a pressure medium and constraining the opening and deformation of a die as well. CONSTITUTION:The material 5 to be worked is arranged at the inner side of a split die 1 and the outer cylinder 2 having larger inner diameter than the outer diameter of the die 1 is arranged by supporting it with a die supporting cylinder 6. In this case, the outer cylinder 2 and the end face of the die 1 are pressed with the load Fo of an end face plate via the rail material of an O ring 7, packing 8, etc. An inner pressure Pi is applied on the material 5 to be worked in the state of applying a pressure Po on the die outer peripheral face and a pressure rod 4 is pressed with a load Fi via an O ring 11 to perform a bulge forming. The inner pressure Pi acting on the die 1 and the stress based on the external pressure Po are superimposed and reduced, so the deformation and opening of the die are reduced. Consequently the forming accuracy of a product is improved.

Abstract: PURPOSE:To restrain the opening on the divided plane of a die, to reduce the deformation and to improve the accuracy after the formation by performing the control in the bulging stage by restraining with adding a pressure on the outer periphery of the die without applying a divided die constraint method by a restraining ring, etc. CONSTITUTION:A work 1 is set inside the divided dies 2, 3 located in an integral type thick cylinder 4. A liquid is first filled by a hydraulic pump 16 into the gap between the divided dies 2, 3 and integral thick cylinder 4 in the forming stage and held at a certain set pressure P2. The liquid is filled by a hydraulic pump 17 into the work 1, the axial tension is added according to priority up to such a forming pressure P2 as becoming the force smaller than the sum F4 of the force F3 calculated from the fastening force F1 of the divided dies 2, 3 and set pressure P2 and the forming inner pressure is added by following to the axial tension up to under the work 1 forming zone conditions. After completion of one step the feedback control of the forming inner pressure and the pressure P2 to fasten the dies is performed to transfer to the succeeding step. The addition is then performed up to the final forming pressure P3.

Abstract: PURPOSE:To unify a stress and to reduce the residual stress by applying the shaft compressing force more than the yielding stress of a blank by reducing the inner pressure after setting a work inside the metal die to form an angular metallic tube and bulge-forming the shaft compressing force and inner pressure by synchronizing. CONSTITUTION:A metal die 1 is quadrifidable with the divided lines intersecting each other at right angles and the hole formed along the center shaft has each rectangular side on its cross section forming the shape curving to the center shaft side. A work is inserted into this metal die 1, a pressing rod 2 is applied from both end parts of the work 3 with a shaft compressing force F and a bulging formation is performed by applying an inner pressure P simultaneously. The shaft compressing force is then increased by reducing the friction force between the metal die 1 and work by reducing the inner pressure as far as possible to reduce the residual stress which is after the bulge forming. The enlarging deformation to the outer side due to the secular change can be controlled as well by reversing the residual stress so as to work to the inner side by forming in a flat shape and by pressing from the inner side each side wall recessed to the inner side.
