The pressure vessel 1 including the upper and lower covers 2 and 3 is held by a press frame 4, and the frame 4 supports the axial force generated when isostatic pressurization is performed using an ultra-high pressure medium. A pressure medium supply/discharge port 8 communicating with the inside of the pressure vessel 1 is provided on the 3 side, and although the port 8 is not shown, it communicates with an ultra-high pressure hydraulic pressure supply equipment side provided outside the pressure vessel 1. be done. In this case, a cold isostatic pressure device uses a liquid pressure medium such as water without heating it, and a warm isostatic pressure device uses a heated liquid pressure medium. A hot isostatic pressurizing device uses a gas body and has a heating source such as an energized heater inside the pressure vessel. This is a directional pressure pressurizing device, and when performing pressure forming, as shown in FIG.
For example, as mentioned above, a molded object 5 in which powder of metal, ceramics, etc. is sealed in a deformable mold is suspended by, for example, a winch of a traveling crane, and a pressure medium 9 is inserted through an upper opening. After placing the molded body 5 on the lower lid 3, the upper lid 2, which is in the retracted position, is moved to a position concentrically above the pressure vessel 1, and the molded body 5 is charged into the container 1, which is filled with the pressure vessel 1. At the same time, the press frame 4, which is also in the retracted position, is moved to a position concentric with the pressure vessel 1, and the pressure vessel 1 is held in a sandwich manner through the upper and lower covers 2 and 3, as shown in FIG. , by supplying ultra-high pressure liquid medium into the pressure vessel through the pressure medium supply/discharge port 8 on the lower lid 3 side, increasing the pressure within the vessel 1, and maintaining this for a predetermined period of time. The molded body 5 is compression molded by isostatic pressing.

対抗する完全なシールができなくなるのである。(Problems to be Solved by the Invention) The problem with the conventional isostatic pressurizing device described above is that the object to be formed 5 is moved in and out of the upper opening of the pressure vessel 1. That is, as shown in Figures 4 and 6,
When the object to be formed 5 is lifted in and out by a wire rope or the like in a winch, interference occurs between the inner surface of the upper opening and the outer surface of the object to be formed 5 at the portion A in the figure due to rocking or the like. There is a risk that the inner surface of the upper cover 2 may be damaged, and the occurrence of such damage corresponds to the fitting closure of the opening of the upper cover 2, making it impossible to form a complete seal against ultra-high pressure.

Pressure vessel 1 that can be opened and closed
In an isostatic pressurizing device in which a pressure medium supply/discharge port 8 is provided on the lower lid 3 side, the upper lid 2 is connected to the pressure vessel 1.
As shown in FIGS. 1a and 1b, on the outer circumferential side of the upper opening of the As indicated by the arrow in FIG. 1a, the upper opening is rotated 90 degrees with respect to the upper opening of the pressure vessel 1, and as shown in FIG. In the illustrated example, a part of the circumferential side of the upper cover 2 is provided with a center position O of the upper cover 2 which is also the center of rotation, and a center O 1 of the upper cover 2. By attaching a protruding opening protection cover 10 with centers O 2 that are out of phase by 90 degrees and positioning the cover 10 at a lower level than the top cover 2 as shown in FIG. 1b, the following can be achieved. This eliminates the problem of interference between the object to be molded and the upper opening. That is, in FIGS. 1a and 1b, the upper lid 2 is raised and opened from the upper opening of the pressure vessel 1 by the lifting mechanism 11, and then the upper lid 2 is lifted 90 degrees.
When the opening protection cover 10 is rotated around the pivot point O and retracted to the outside of the pressure vessel 1, the opening protection cover 10 is positioned at the center of the upper opening of the pressure vessel 1, as shown by the dotted line in FIGS. 1a and 1b. We will be making a turn together. Therefore, by vertically lowering the top cover 2 from the dotted line position shown in FIG. 2b using the lifting mechanism 11, the opening protection cover 10, which is positioned concentrically with the top opening, is moved from the dotted line position shown in FIG. 2b. It descends together and is fitted into the upper opening in a recessed manner, as shown by the solid line in the figure.

れるのである。 That is, if the object to be formed is carried in and out in this state, there will be no interference trouble between the object to be formed and the inner surface of the upper opening, and no damage will occur to the inner surface of the upper opening. After carrying in and setting the molded object in the above state, when removing the opening protection cover 10 and closing the upper lid 2, as shown in FIGS. 2a and 2b,
As shown in FIG. 1b, once the opening protection cover 10 and the top cover 2 are raised from the solid line position to the dotted line position in the same figure by the lifting mechanism 11, and the cover 10 is raised and retracted from the opening, the top cover 2 is moved to the pivot point O. The upper cover 2 is thereby positioned concentrically with the upper opening, and the cover 10 is pivoted out of the pressure vessel 1 and completely retracted. , the upper lid 2 is closed to the upper opening by the lifting mechanism 11, the pressure vessel 1 is held by the press frame 4 via the upper and lower lids 2 and 3 as is known, and ultra-high pressure medium is supplied, the pressure is increased, etc. Direct pressure molding is performed on the molded object 5.

から防止できる。 In other words, in the conventional technology disclosed in Japanese Utility Model Application Publication No. 62-37663, the top cover and the protection ring (opening protection cover) are driven separately, so there is a risk of interference with each other, whereas in the present invention, the top cover and the opening protection ring are driven separately. Since the covers are integrally formed, they do not interfere with each other. In addition, since the frame and the conveyor crane approach and leave the vicinity of the top lid of the isostatic pressurizing device, if the protection ring was of the folding type as in the conventional technology, interference with these would be a problem. The present invention can prevent such interference because it moves vertically up and down and moves horizontally.

同時期になされ、いびつになるおそれもない。 Furthermore, in the conventional technology, the protective ring (opening protection cover) is fitted into and removed from the upper opening by tilting it up and down, so the side closer to the lifting fulcrum is fitted into and removed from the upper opening more quickly, and the side farther from the lifting fulcrum is fitted into and removed from the upper opening more slowly. However, in this invention, the opening protection cover is moved up and down in the vertical direction and moved in the horizontal direction to fit into and remove from the upper opening. This is done at the same time throughout the entire cover, so there is no risk of it becoming distorted.
