2. Description of the Related Art For example, when manufacturing a lid having a flange on the periphery of a hemisphere, as shown in FIG. 5 (a), a hemisphere 21 and a flange 22 are individually manufactured, and these hemispheres are formed. The lid 23 is obtained by forming a groove on the flange 21 and the flange 22 and then welding and joining the hemisphere 21 and the flange 22. For example, it is very troublesome to manufacture a thick-walled material such as the top lid of a nuclear reactor vessel by such a method. Therefore, when manufacturing a thick-walled lid, FIG. As shown in (), the lid 33 is obtained by forging a thick material so as to integrally form the hemisphere 31 and the flange 32, and then performing cutting to a predetermined size. .

However, when a thick-walled material such as the top lid of a nuclear reactor vessel is manufactured by forging as described above, a large pressing force is required for the processing, so that a large scale is required. Therefore, the equipment that can be implemented is limited. For this reason,
It has been strongly desired that the above processing can be performed without a large-scale press machine.

First, as shown in FIG.
While setting the material 10 thereon, the base die 1 is attached to a slide of a press (not shown), and then the slide of the press is operated to press the material 10 as shown in FIG. 4B. At this time, the intervening body 6 is removed.

When the material 10 is pressed in this way,
Since the pressing die 5 presses the peripheral edge of the material 10 against the receiving base 7, the material 10 is held without being shifted with respect to the receiving base 7, and the front end side of the first pressing die 2 moves around the central portion of the material 10. Since the pressing is performed, the corresponding portion of the material 10 is pressed (see FIG. 4C). At this time, since the second pressing die 4 is housed inside the first pressing die 2 without protruding from the tip of the first pressing die 2, the second pressing die 4 does not participate in the pressing of the material 10. For this reason, the pressing force of the press machine is concentrated on the first pressing die 2 without being applied to the second pressing die 4.

When the periphery of the central portion of the material 10 is pressed by the first pressing die 2 in this manner, the press by the pressing machine is released once, the base die 1 is pulled up, and the intermediate body 6
After the base end of the second pressing die 4 is extended by inserting into the inside of the first pressing die 2, when the press by the press machine is started again,
With the contact between the distal end surface of the base die 1 and the base end surface of the first die 2, the base die 1 is moved through the intervening body 6 into the second die 4.
, And the tip of the second pressing die 4 is made to protrude from the tip of the first pressing die 2, so that by pressing, the tip of the second pressing die 4 presses the central portion of the material 10,
The portion of the material 10 is pressed to form a lid having a flange on the periphery of the hemisphere (see FIG. 4D).

That is, the pressing force of the press is concentrated on the first pressing die 2 to press the periphery of the central portion of the material 10, and then the pressing force of the pressing machine is applied to the second pressing die 4 so that the material 10 is pressed. Press the central part of
The material 10 is pressed as a whole by combining the pressing of the press machine with the pressing force concentrated on a specific portion of the material 10. For this reason, since the pressing force of the press machine can be used to the maximum, even the thick material 10 can be sufficiently pressed.
