Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a proposal of a new container for storing a sample to be molded used in a warm isostatic press.

(Prior Art) It is well known that there is a cold, warm, and hot isostatic pressing device as one of the pressing techniques for various metals and ceramic powders, without exemplifying it. That is, generally, both ends in the axial direction are sealed by an upper lid and a lower lid, and the object to be treated is loaded into a pressure container capable of supplying a pressure medium (gas or liquid), and the pressure medium is supplied and pressure is increased. In the warm type and the hot type, heating by a heating device is performed in parallel to perform isotropic pressure molding of the object. As a material to be treated used in such a hydrostatic pressure device, for example, a polymer material such as a super heat resistant engineering plastic has been attempted to be pressurized under hydrostatic pressure at a temperature of several hundred degrees C. In recent years, the heat resistance of plastics has been dramatically improved with the development of the aircraft and space industries, and a wide variety of materials have been developed.

Since it is so-called generally called special engineering plastic, it is also known that PSF, PES, PEEK and the like correspond to these. Such super heat resistant plastics are often difficult to form due to their super heat resistance, and there is a problem that thermal decomposition occurs when trying to heat to a temperature range suitable for the molding. In order to avoid such a problem, recently, there has been an interest in an attempt to heat and mold such a polymer material under pressure. Water pressure device (C
A warm isostatic pressurizing device (WIP device) having a heating function of about several hundred degrees C. is suitable for the IP device), but it is not always popular at present and the material to be treated is accommodated at this time. As for the sample container corresponding to the molding mold, the one conventionally used in the conventional cold isostatic pressing device (CIP device) is often used as it is, as shown in FIG. Regarding Figure 3b,
An outline of a sample container used in a conventional cold isostatic pressing device (CIP device) will be explained. That is, as shown in both figures, the rubber bag 21 or the rubber tube 22 and the rubber plugs 23, 2
3, the target sample 24 is filled in the bag 21 to the tube 22 and sealed with a rubber band 25, which is immersed and set in a hydraulic medium in a pressure vessel (not shown) and set to 1000 ~
The isotropic pressure molding process is performed under a pressure of 5000 kgf / cm ² at a heating temperature of several hundred degrees C. Urethane rubber, silicon rubber, etc. are generally used as the rubber material. Of.

(Problems to be Solved by the Invention) The above-described conventional sample container has the following problems. That is, although these urethane rubbers, silicone rubbers and the like have heat resistance to each, in the molding temperature range of the super heat resistant plastics, the heat resistance is not sufficient, and even if a material having a high heat resistance is used, There is a problem in that its size and shape are limited, or the cost itself is extremely expensive, and there is also a problem in durability with bags and tubes, and it is disadvantageous in that repeated use is difficult. is there.

(Means for Solving the Problems) The present invention is a modification of the rubber mold type, which has heat resistance and expands the molding freedom without limitation on the size and shape of the rubber mold type, and can be easily used repeatedly. The present invention aims to provide a sample container for a costly warm hydrostatic pressure device (WIP device), and specifically, has a space part capable of accommodating a sample inside and a flat surface at its inlet part. The metal storage container having a flange portion and at least the surrounding wall forming the space is a thin wall portion, and a thick lid having a flat surface capable of contacting a flat surface of the storage container. A sealing member is provided between the flat surfaces that are brought into contact with each other, and the contact is made in a pressure-tight manner by the clamp means. Further, the lid is degassed in the storage container or pressed in the storage container after processing. Possible An opening to
The sample container is further provided with the opening closing member, and the sample container is combined with a metal holding container that fits and holds the space of the storage container and is provided with a large number of pressurizing pressure medium introduction holes. Especially.

(Operation) According to the above technical means of the present invention, in FIG. 1, the storage container 1 formed of, for example, an aluminum-based metal material has a space portion 2 for storing a sample therein and an inlet portion 3 thereof. Has a flange portion 5 having a flat surface 4, and at least the surrounding wall 1a of the container 1 forming the space portion 2 is a thin portion, and is a flat surface contacting the flat surface 4 of the storage container 1. 7 and the seal member 8 on the flat surface 7 thereof.
The sample container of the present invention is constituted by the thick lid 6 having the mounting groove portion 9 and the storage container 1, and the storage container 1 and the lid 6 are assembled by the clamp mechanism 10 which is a clamping means. By being disassembled, the flat surfaces 4 and 7 maintain the sealing property under pressure through the sealing member 8, and the lid 6 holds the storage container 1
An opening 14 that enables deaeration of the inside or pressurization inside the storage container 1 after pressure molding, and a closing member 13 that closes the opening 14.
Further, as shown in FIG. 1, when the storage container 1 and the lid 6 are fastened and integrated by the clamp mechanism 10, in the present invention, at the same time as the storage container 1, the space portion of the same container 1 is provided. The holding container 11 formed by, for example, a stainless steel material or the like in which the two 2 are fitted and held and in which a plurality of pressurizing pressure medium introduction holes 12 are formed can also be integrally clamped and held. It produces an action. That is, according to this, the sample is filled in the space 2 of the storage container 1, the lid 6 is closed, and the clamp mechanism 10 integrally clamps the sample. The thin-walled portion 1a of the storage container 1 is rapidly deformed as shown by the broken line in FIG. 1, and the internal pressure is applied against the action of external pressure. However, the thick-walled lid 6 is hardly deformed during the press-molding, so that the thick-walled lid 6 can be repeatedly used as it is. Further, when the sample is molded and solidified by the desired heating and pressure molding process, it is difficult to take out the sample if the storage container 1 is deformed. Therefore, the closing member 13 in the lid 6 is removed and the inside of the storage container 1 is removed. For example, compressed air pressure can be applied from the opening 14 to return the storage container 1 to the original state.
It is possible to maintain the shape when the material is restored and prevent excessive expansion damage. When the holding container 11 is used, the storage container 1 is in close contact with the inner wall of the container 11,
If it is reused, use it as it is. Therefore, since a large number of pressure medium introduction holes 12 are formed in the holding container 11, it works effectively.

(Embodiment) A suitable embodiment of the present invention will be described with reference to FIGS.

Each of the examples shown in FIGS. 1 and 2 shows a combination of the storage container 1 and the holding container 11, but the material of the storage container 1 is several hundred degrees C, which is the operating temperature range. A material that is not so high in strength and rich in ductility, that is, an aluminum-based metal material that is easily deformed and has high deformability is preferable.
In the embodiment, the storage container 1 has a cup-like shape having a space portion 2 for storing a sample, and an inlet portion 3 thereof is formed with a flange portion having a smooth flat surface 4 as an overhanging shape. . In this formation, for example, the plate material is obtained by press forming, but it is also possible to form the plate material by spinning. The surrounding wall 1a forming the space portion 2 in the storage container 1 is made thinner than at least other portions. According to the spinning process molding at this time,
It is also possible to reduce the thickness of only the space portion 2 and increase the thickness of the flange portion 5. The lid 6 having the same smooth flat surface 7 that contacts the flat surface 4 on the lower surface is a disk-shaped thick lid, and the flat surface 7 that contacts the flat surface 4 is provided with a groove portion 9 that surrounds in a ring shape. Then, the seal member 8 made of a rubber O-ring is installed in the groove 9. Since the O-ring has a relatively simple shape, it is easy to use a special heat-resistant material such as Kalrez (trade name, manufactured by DuPont).

At the center position of the lid 6, an opening 14 with a female screw for enabling depressurization of the storage container 1 or pressurization in the storage container 1 after pressure molding is provided.
It is provided together with 13, so that the deformation and restoration of the container 1 at the time of shaping the molded body described above in the section of operation can be easily performed, and the vacuum treatment and the like can be obtained without any trouble.

In both of the embodiments shown in FIGS. 1 and 2, the holding container 11 is clamp-integrated together by the clamp mechanism 10, and the storage container 1 is made of metal for the purpose and preferably has corrosion resistance and It is made of high-strength stainless steel and has a cup-like shape with a flange portion 11a at the upper end, which is closely fitted to the storage container 1 and has a large number of pressure medium introduction holes 12 on its entire peripheral surface. In addition, the outer surface of the storage container 1 is lined up in a reaching manner so that pressure can be applied. The clamp mechanism 10
The one shown in FIG. 1 has a clamp ring shape with a U-shaped cross section, and the lid 6 and the flange portions 5 and 11 a are commonly clamped, and can be retained by the clamp bolt 15. By this clamp, the sealability of the flat surfaces 4 and 7 is maintained at the time of pressurization through crimping of the seal member 8 which is a seal ring.

In the embodiment shown in FIG. 2, instead of the clamp mechanism 10 shown in FIG. 1, the lid 6 is detachably clamped to the flange portion 5 of the storage container 1 by the screw fitting mechanism 10a. Is. The screw fitting mechanism 10a portion of the flange portion 5 has a thick structure. In this case, however, since the hydraulic medium penetrates up to the seal member 8 portion, the screw fitting mechanism 10a portion is not deformed. After the pressurization, the lid 6 can be disassembled and removed. Further, in this case, when the holding container 11 is used in combination, the flange portion 11a of the container 11 is used.
Is attached to the flange portion 5 with bolts 16.

In the embodiment described above, the shape of the storage container 1 is arbitrary, and is not limited to the illustrated example. Also, instead of the holding container 11,
It is also possible to prepare a jig such as a split mold.

(Effect of the Invention) The sample container of the present invention is superior in the following points to the rubber-made or rubber-mold type sample container using a rubber tube used in the conventional cold or warm hydrostatic pressurization device. .

According to the sample container including the storage container 1 and the lid 6 of the present invention,
Compared with the rubber mold type, it is possible to provide a sample container for a warm hydrostatic pressurizer that is ruggedized and can be used repeatedly, and that has no size and shape restrictions at all, at low cost. According to the combination with the holding container 11,
The sample removal after pressure molding is also facilitated. Also in this case, the important sealing property of the sample container is that the sealing member 8 on the flat surfaces 4 and 7 is brought into close contact by pressurization, and it is possible to highly stably maintain a high level of sealing property. Is large. As the application of the sample container according to the present invention, the super heat-resistant engineering plastics material is exemplarily described as an application in the embodiment, but the application is not limited to the same application. Needless to say, it can be applied to, for example, a warm hydrostatic pressure device of a liquid organic substance.
