圧プレス装置に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention is a method of storing powder of metal, ceramics, etc. in a flexible molded container and applying isotropic pressure to the fluid heated in the high-pressure container. This invention relates to a warm isostatic press device for pressure forming.

た（特開昭61−124503号公報）。(Prior Art) The applicant first provided a flexible forming container containing powder of metal, ceramics, etc. in a high-pressure container into which a heated fluid was injected and then pressurized, and is connected to a vacuum evacuation device outside the high-pressure container via a connecting pipe, the pressure and temperature of the pressure fluid are applied to the powder in the forming container, and the gas generated in the forming container is discharged to the outside. proposed a method in which the powder was compactly compacted by compaction (Japanese Unexamined Patent Publication No. 124503/1983).
（発明が解決しようとする問題点）
該圧力流体の温度は約300℃以下の比較的低い

ない金属材料にて成形容器を形成することが好ま
しい。(Problem to be Solved by the Invention) Since the temperature of the pressure fluid is relatively low, about 300°C or less, it is unlikely that the forming container will soften due to temperature, and it is difficult to maintain a good pressurizing force of the fluid. In order to obtain a good molded product by acting on the powder, it is desirable that the molding container be made of a flexible material such as Cu or Al. If the forming container is made of rubber, its flexibility will be improved, but rubber contains many gas molecules, which leak out during the evacuation operation, making it difficult to obtain a good vacuum and causing damage to the molded product. It is also undesirable for gas molecules to be mixed in, and therefore it is preferable to form the molded container from a metal material from which gas molecules are less likely to gush out.

できない。 However, since the high-pressure vessel is made of a metal material such as an Fe-based alloy with high strength, it is necessary to connect the connecting pipe to prevent gas molecules from gushing out in a vacuum and to make the high-pressure vessel airtight. It is preferable to make it from SUS, which can be connected to this, but a SUS connecting pipe cannot be joined to a Cu or Al molded container.

に接続することが出来る。(Function) The high-pressure container is made of an Fe-based alloy so that it can withstand fluid heated to about 300°C supplied from a pump via a heater and pressurized to 3000 kg/cm 2 . A flexible molded container provided within the high-pressure container is heated and compressed using pressurized fluid, and the powder of metal or the like inside the container is press-molded into a solid state. At that time, the inside of the molding container is connected to a vacuum evacuation device outside the high-pressure container via a connecting pipe, and gas molecules generated during molding of the powder can be exhausted to the outside to obtain a dense molded product. , the molded container is made of Cu, and one end of the connecting pipe is made of SUS material so that it can be welded to the Fe-based alloy high-pressure container, and the other end is made of Cu material.
It can be pressed into a Cu molded container, and it can be placed between the two parts.
Since it is made of a Ni member that can be pressed against SUS and Cu, the high pressure container and the connecting pipe can be connected together in an airtight manner. In addition, when the molded container is made of Al, the other end side is made of an Al member, and between the SUS member on one end side there is a Ni member that can be pressed against the SUS, and the other end side is a Ni member that can be pressed against the Ni member. By interposing a Cu member that can be pressure-welded with the Al member, the high-pressure container, the molded container, and the connecting pipe can be integrally and airtightly connected.
