The present invention is to put the material to be treated, such as pre-formed metal powder in a high-pressure container equipped with a heater and to apply ultra-high pressure with a fluid or gas medium in the container and pressurize the material while heating with a heater to increase the efficiency of the production facility A hot isostatic pressing apparatus (hereinafter referred to as a HIP apparatus).

The present invention also relates to an apparatus in which the continuous transfer of material to be treated from one station to another is carried out automatically in an enclosed operating space in the stepwise execution of the necessary processing steps for various materials to be treated, including metallic materials. .

The invention also relates to an apparatus for automatically detecting the leakage of a seal in a continuous HIP apparatus. Hot hydrostatic pressurization device is one of ultra high pressure forming technology and is called as HIP device without special explanation. In the HIP apparatus, when a material to be treated, such as a preformed metal powder, is placed in a high pressure vessel equipped with a heater and the inside of the container is vacuumed or an active or inert gas atmosphere is applied to the container or an ultrahigh pressure with a fluid or a gas medium, the material is It is press molded into a brick-like form. The actual production facility of such a device consists of a high-pressure container having a closed structure in which a part of the container can be opened and closed by a cover, and as is well known, the cover is closed from the outside when the cover is closed. Only a mechanism for opening and closing the cover and a device for putting or removing the material to be processed into the container are installed exposed to the outside of the container and complicated handling operations are required.

Conventional heaters used in high pressure vessels have generally used heaters using heating wires made of molybdenum or graphite group materials at relatively high temperatures. However, since such a heater is oxidized (consumed) when exposed to air, it is necessary to wait until the heater is cooled to some extent after the high temperature and high pressure is removed when taking out the material to be pressurized and formed into a sealed state in the container from the high pressure vessel. This results in longer cycle times and lower productivity.

② In addition, since the material to be treated in the previous stage of HIP treatment should be put into the device under normal temperature and normal pressure, the temperature and pressure should be increased, thereby increasing the pressurization cycle and reducing productivity.

In addition, molybdenum and graphite group heaters require a non-oxidizing atmosphere because they are oxidized in a high temperature atmosphere, and there is a need for a special atmosphere in which the material to be treated cannot be taken out at a high temperature in this atmosphere.

In most cases, only one step is necessary to form the metal material to be processed from the raw material to the final product, and several steps are required after preforming, and high temperature treatment also requires heat treatment such as heating. Most of these operations are performed in separate locations, so a transfer mechanism for transferring raw materials and semi-finished products from one station to another is required. Conventionally, conveyors or other transfer means have been used to transfer these materials while being exposed to the atmosphere.

If special materials or temperatures are required for the material to be treated, transport mechanisms should also be specially considered. For example, in an ultra-high pressure hydrostatic pressurization apparatus known as a HIP apparatus, a material to be treated, such as a preformed metal powder, is placed in a high pressure vessel equipped with a heater, and the inside of the vessel is vacuumed or an active or inert gas atmosphere. When ultra-high pressure is applied to the fluid (liquid, gas) in the container, the material is press-molded in the form of a brick. However, this device is basically composed of a high-pressure container which is cut off from the outside by a cover that can be opened and closed. Only the device which opens and closes the cover and the mechanism for putting or removing the material to be processed into the container are exposed to the outside of the container. . Conventional heaters used in high-pressure containers usually use a heater using a heating wire made of molybdenum material or graphite group material.

However, since such a heater is oxidized (consumed) when exposed to air, it is necessary to wait until the heater is cooled to some extent after the high temperature and high pressure is removed when taking out the material to be pressurized and formed into a sealed state in the container from the high pressure vessel. In addition, the material to be treated in the previous step of the HIP treatment should be set in the apparatus under normal temperature and pressure, and then the temperature and pressure should be raised. As a result, the pressurization cycle is long and productivity is reduced. The use of conventional transport means when heating the material to be treated in a separate pretreatment step requires complicated equipment and complicated operation on both sides of time and place.

Of course, not only the HIP apparatus but also the apparatus for carrying out the stepwise operation in a separate place should be provided with a transfer apparatus. If a special temperature or atmosphere is required for the material to be treated, the members constituting the device must also meet such conditions, which is often inconvenient with conventional conveying devices.

The present applicant has developed a so-called continuous hot hydrostatic pressurization device designed to transfer a high pressure vessel for hot hydrostatic pressure molding and an operation chamber for inserting or withdrawing a material to be treated by a closed tank so that the material to be treated is transported in the sealed tank. It would be.

In the above-mentioned continuous HIP system, it is extremely difficult to keep the operating chamber, the high pressure vessel, and the closed tank under the same pressure and atmosphere.

If the atmosphere is not balanced, for example, when the material to be treated is inserted into a sealed tank and transported, if the pressure balance between the high pressure vessel, the operating chamber and the closed tank is lost, the material to be treated may fall or be blown away by air pressure. have.

As a HIP apparatus for press-molding a material to be treated such as metal powder or the like, an apparatus has been proposed in which operations from insertion to extraction of a material to be treated are continuously performed from one station to another station.

As an example of such a device, in a main station where the material to be treated is directly press-molded, the high pressure vessel is opened in a closed tank and the movable cover on which the material to be treated is installed is connected to the bottom of the high pressure vessel so that the internal pressure of the high pressure vessel is separated. Is about 200 to about 2000 kgf / cm ² , while the closed tank has a device of about 2 kgf / cm ² vacuum in an active or inert gas atmosphere. Since the sealing material of the part in contact with the movable cover is repeatedly opened and closed, damage is likely to occur, which is very likely to cause leakage of the seal.

However, conventionally, since there is no device for detecting damage to the sealing material, if such damage occurs, a high pressure flow occurs to a low pressure sealed tank, and the sealed tank is damaged.

Because of this, it is necessary to increase the thickness of the sealed tank and the thickness so that the sealed tank does not break even if the leak occurs in the sealed, so the size of the sealed tank is increased and the weight is increased.

Conversely, if a failure occurs in the high pressure gas generator that supplies the high pressure gas into the high pressure container, the high pressure gas flows back from the closed tank to the high pressure container, thereby making it impossible to maintain the atmosphere of the closed tank.

According to the present invention, regardless of the opening / closing operation of the HIP device, the material to be treated can be inserted at a high temperature where the heater is heated, and the HIP-treated material is to wait for the temperature of the heater to be lowered to a temperature that can prevent oxidation of the heater. Since it can be taken out of the container without the need for it, the cycle time can be reduced and the productivity of the HIP device using this type of high pressure container can be improved.

[Invention (I)]

As shown in Figures 1a, 1b and 1c, the apparatus consists of a main station 31 and an auxiliary station 32, in which the high pressure vessel 2 has one end (in the illustrated embodiment). A movable cover for opening and closing the opening 2a for opening the one end, i.e., the material 5 to be processed into and out of the container 2, with the lower end of the opening being firmly mounted on the upper portion of the pressing frame 1; 8a is disposed below the pressing frame 1 via the hoisting device 9, and the lid 8a is moved up and down with respect to the opening 2a, and the material 5 to be processed into and out of the container 2 One end of the operating chamber 11 is provided at the auxiliary station 32 which is integrally provided on the upper surface of the movable cover 8a and moves adjacent to the main station 31. In the example, the lower tip is opened as the opening 11a and used as the opening and closing cover 10, (the means for opening and closing the cover is operated manually or automatically). Is provided with the other end (upper in the illustrated embodiment), the movable cover 8b for opening and closing the opening 11a is opened as the opening 11a by the lifting device 13 and the opening and closing cover 10 (cover The means for opening and closing the door is operated manually or automatically.) And the movable cover 8b for opening and closing the opening 11a is provided on the elevating device 13. It is equipped to move up and down with respect to the opening 11a, and the member 7b which moves the material 5 to be processed in and out of the operation chamber 11 is integrally provided in the upper surface of the movable cover 8b.

The material 5 to be treated with this device is provided by the container 2 by means of a member 7a provided on the upper surface of the movable lid 8a and the closing of the movable lid 8a with respect to the opening 2a of the high-pressure container 25. Can be filled in.

Thus, the material 5 treated under these conditions is not shown but the thermal insulation layer 3 under the ultra high pressure of the fluid or gas medium sealed in the container 2 and in a vacuum or active or inert gas atmosphere in the container as is well known. It can be molded by hot hydrostatic pressure by heating by a heater 4 installed in the container 2 via.

As in the known art, a high pressure gas generator, a vacuum device, a container cooler, an energy supply device for a heater, and the like are attached to the HIP device body.

On the other hand, in the auxiliary station 32, a movable cover 8a provided with a member 7b for moving the material 5 to be processed provided on the upper surface of the auxiliary station is provided with respect to the opening 11a of the operating chamber 11. Made to be openable and close, the operating chamber 11 can be utilized to apply the necessary treatment operations before and after pressing of the material 5 to be treated. For example, the movable cover 8b is moved to the opening 11a, the opening and closing cover 5 of the operating chamber 11 is opened in communication with the atmosphere, and the material 5 to be treated before pressing is put into the operating chamber to be treated. The material 5 is placed on the member 7b. After closing the opening / closing cover 10 to independently seal the operation chamber 11 to make the atmosphere like a closed tank, the movable cover 8b is prepared to transfer the material 5 to be processed with respect to the main station 31. Is moved down as. On the contrary, the movable cover 8b is closed over the opening 11a in a state where the material to be processed 5 that is already pressurized is placed on the member 7a of the movable cover 8b via the supporting member 6. After the material 5 is supplied to the operating chamber 11 at atmospheric pressure, such as a closed tank, the opening and closing cover 10 is opened. Thus, in the auxiliary station, various other operations such as pre-treatment and post-treatment required before and after the insertion and withdrawal of the material to be treated and the treated material are pressurized can be executed independently, and these operations are also performed by the main station 31. Can be implemented in combination with the pressing operation.

The enclosed tanks 12a and 12b surrounding the outer circumferences of the main auxiliary stations 31 and 32 in communication with the inner spaces 31a and 32a of the main auxiliary stations 31 and 32 are hermetically coupled to block the outside. The two spaces 31a and 32a are isolated from the outside.

The spaces which communicate with each other are formed so that the gas cylinder 51 and the vacuum pump 53 can communicate with one side of the sealed tank 12a or 12b so that the internal spaces 31a and 32a are formed in the high pressure vessel 2. It may be in a vacuum or in the same atmosphere as an active or inert gas atmosphere. An object of the present invention is a transfer member 14a movably installed between an interior space 31a, 32a and a support member 6 for the material 5 to be treated separably held above the transfer member 14a. It can be easily achieved by the installation of the transfer device 14 consisting of. In the illustrated embodiment, the transfer device extends outward but can be stored in the tank. In particular in FIG. 1 a, the material 5 to be treated is located on a support member 6 that engages the transfer member 14a and when the support member 6 overlaps the member a on the movable cover 8a. If the material 5 to be treated has not been pressurized yet, the coupling between the conveying member 14a and the supporting member 6 is released and the movable lid 8a is then closed to close the opening 2a of the high pressure vessel 2. The material 5 to be raised and processed is introduced into the container 2 by the support member 6 and the member 7a to perform hot hydrostatic pressure on the material 5 to be treated under predetermined high pressure and high temperature treatment conditions.

In addition, if the material 5 to be treated is already pressurized, after the conveying member 14a and the supporting member 6 are combined, the conveying member 14a is moved in the right direction as shown in the drawing to support the supporting member 6. And the material 5 to be pressurized are transferred to the auxiliary station 32 and when the support member 6 has reached a position where it overlaps with the member 7b on the movable lid 8b of the station 32, The member 14a is arranged and the coupling between the member 14a and the support member 6 is released. Next, when the movable cover 8b is raised, the movable cover 8b closes the opening 11a of the operating chamber 11 and simultaneously the material 5 and the supporting member 6 to be processed are transferred to the operating chamber 11. In this case, only the inside of the operating chamber is maintained at atmospheric pressure, while the inside of the closed tank is maintained in a vacuum, active or inert gas atmosphere.

Therefore, the material 5 to be treated can be taken out through the opening and closing cover 10 independently of the closed tank. In particular, the closed tank of the material to be treated before pressurizing with the high pressure vessel may be inserted while the heater maintains a high temperature because the heater is in an atmosphere where the heater is not oxidized. On the other hand, when taking out the material 5 to be treated which has already been pressurized from the high pressure vessel 2, the interior spaces 31a and 32a are brought into the atmosphere in the container 2 through the closed tanks 12a and 12b. Since the movable cover 8a can be in an atmosphere such as the following, after the completion of molding without having to wait until the temperature is lowered to the heater oxidation temperature after completion of molding in the container 2 to take out the material 5 to be treated. Immediately move down and open, significantly reducing cycle time. Furthermore, the upward movement of the material 5 to be processed can be automatically performed in the shortest distance by the movable lids 8a, 8b and the conveying device 14 provided in the respective stations 31, 32. In addition, since the substation 32 can be increased to the required number for one unit of the main station 31, the pressurization cycle of the actual manufacturing equipment including all pre and post treatments required for the material 5 to be processed is carried out. It can shorten and greatly improve efficiency and productivity.

The rack gears 37a and 37a mesh with the gears 35 and 35, and the conveying members 14a and 14a are driven by the vertical movement of the rack rod and the rotation of the gears 35 and 35. The clamp holders 14b and 14b may be coupled to and separated from the support member 6 because they are rotated forward and backward.

According to the above-described embodiment, the interior of the sealed tanks 12a, 12b is in the same vacuum as the high pressure vessel 2, or in an active or inert gas atmosphere, and the movable cover 8b of the auxiliary station 32 is operated. It is moved upward to close the opening 11a of the chamber 11 to block the operation chamber 11 from the internal space 32a. The movable cover 8b is located in the operating chamber and the opening and closing cover 10 is opened so that the material 5 to be processed is placed on the movable member 7a together with the supporting member 6 while the opening and closing cover 10 is The interior of the operating chamber 11 is closed so as to have the same atmosphere as the inner space 32a, and then the movable cover 8b, the movable member 7b, the supporting member 6 and the material 5 to be treated are all moved downward. do.

Next, the conveying members 14a, 14a are moved to advance the clamp holders 14b, 14b at positions corresponding to the circumferential side of the support member 6, and the clamp holders 14b, 14b are It is rotated through the rotation of the conveying members 14a and 14a to be coupled to the circumferential side of the supporting member 6 as shown in FIG. 1c, and then the conveying members 14a and 14a are connected to the cylinder 24. It is moved toward the main station 31 by. The conveying members 14a and 14a are stopped at the position where the supporting member 6 overlaps on the movable member 7a of the movable cover 8a, and the clamp holders 14b and 14b are the conveying member 14a. Is rotated to break the engagement between the 14a and the support member 6, and then the movable lid 8a is moved upwards to close the opening 2a of the high pressure vessel 2, and the material 5 to be processed. The material 5 is put into the container 2 by the movable member 7a and the supporting member 6, and the material 5 to be treated according to a known method is subjected to hot hydrostatic pressure. After the pressurization is completed, the movable lid 8a immediately moves downward to take out the material 5 to be processed from the container 2, and in the state shown in FIG. 1a, the clamp holders of the transfer members 14a and 14a ( 14b), 14b and the support member 6 again engage to move the support member 6 and the material 5 to be processed toward the auxiliary station 32 and release the clamp holder 14b from the support member 6. do.

The movable cover 8b moves upward, and the support member 6 and the material 5 to be processed are transferred to the operating chamber 11 through the movable member 7b. With the opening 11a of the movable cover 8b closed, the operating chamber is brought to atmospheric pressure, and then the opening and closing cover 10 is opened so that the material 5 to be processed is taken out, and a new material to be processed to repeat the press cycle ( 5) is mounted on the supporting member 6. That is, the pressurization cycle proceeds completely automatically. Since the heater is cut off from the atmosphere and the heater is not oxidized even when the heater is in a hot state of activation, the insertion and withdrawal of the material to be treated from the high pressure vessel is performed regardless of the anti-oxidation temperature of the heater, resulting in improved productivity and uniformity. Stable operation is performed.

Example 2

In Embodiment 2 shown in FIGS. 2A and 2B, two auxiliary stations 32A and 32B are arranged adjacent to each other with the main station 31 in between. The auxiliary station 32A is an insertion station of the material 5 to be processed and the auxiliary station 32B is a takeout station of the material 5 to be processed. This station may be a composite station in which cooling and preheating members described later are combined therein.

Since the same symbol as that used in Example 1 represents the same member as that of Example 1, the difference between Example 1 and Example 2 will be described. In the insertion auxiliary station 32A, a gas supply line 54a, a vacuum pump 53b, and a pipeline 55 are installed in an operating chamber 11A provided with an opening and closing cover 10a, and an extraction auxiliary station 32B is provided. ), Gas cylinders 51, vacuum pumps 53a, 53c and pipelines 54, 55 are installed on the side of the operating chamber 11B provided with the opening and closing cover 10b, and the sealed tank 12b. Is provided.

The movable auxiliary member 32b is provided with the movable member 7b, the movable lid 8b, and the elevating device 13, while the ejection auxiliary station 32B is provided with the movable member 7b, the movable lid 8b, and the elevating device. The device 13B is installed. Needless to say, the closed tanks 12a, 12b commonly cover the interior spaces 31a, 32a, 32a of the stations 31, 32A, 32B. As shown in FIG. 2B, in the conveying apparatus 14, the stations 31, 32A, and 32B are arranged at regular intervals at the same pitch on the parallel conveying members 14a, 14a. Two parts of the clamp holders 14b and 14b are disposed at the place, and the clamp holders 14b and 14b are provided to have the same pitch as the former.

In this embodiment, hot hydrostatic pressurization on the material 5 to be treated and insertion take-out of the material 5 to be treated are executed in the following process. In the state shown in FIG. 2A, the material 5 to be processed is already pressed at the central main station 31 and the movable member 8a is moved downward so that the material 5 to be processed is taken out and the movable member 7a and Assuming that the state moves downward from the high pressure vessel 2 together with the supporting member 6b, the operation of the insertion auxiliary station 32A during pressurization at the main station 31 is as follows.

The movable member 8b moves upward to close the opening 11a of the operating chamber 11A, open and close the lid 10, and move the new material 5a to be processed together with the supporting member 6a together with the movable member 7b. Inserted into the top, the opening and closing cover is closed, and the inside of the operating chamber is made to have the same atmosphere as the inner space, and then the movable cover 8b is moved downward to prepare the material 5 to be treated as shown in FIG. 2A. The support member 6a and the movable member 7b are pulled into the inner space 32a. From the illustrated state, two sets of clamp holders 14b and 14b of the transfer members 14a and 14a are supported by the supporting members 6a and 6b of the stations 32A and 31. The material to be treated 5b, which has been engaged and has been moved to the right as seen in the drawing, with the conveying members 14a, 14a moved opposite to the movable member 7a of the movable lid 8c of the take-off auxiliary station 32B. Direction is moved through the support member 6a, while the new material 5a to be treated moves the support member 6a toward the opposite direction of the movable member 7a of the movable cover 8a in the main station 31. Go through.

The conveying members 14a and 14a are stopped and two sets of clamp holders 14b and 14b are separated from the supporting members 6b and 6a, respectively.

The movable cover 8a, 8c is moved upward by the main station 31 and the elevating devices 9, 13B in the take-off auxiliary station so that the new material 5a to be treated is hot hydrostatically pressurized. The material to be treated 5b, which has already been pressurized, enters into the operating chamber 11B in the take-off station 32B while entering into the high pressure vessel 2 in 31.

In addition, the operation chamber becomes an atmosphere like a closed tank, and the opening and closing cover 10b is opened to take out the material 5b to be treated. During both operations, in the insertion assistant station 32A, insertion of the new material 5 to be processed in the operation chamber is performed.

In this way, the operation in the state of FIG. 2A is repeated to insert, press, and take out the material 5 to be treated. In this case, insertion, pressurization and ejection are each independent and the productivity is further improved than in Example 1. Also ejection insertion of the treated material can be done simultaneously.

Since the heater maintains a continuous energy supply condition, it is possible to shorten the time of the pressurization cycle as a whole and to facilitate continuous operation.

Example 3

In the third embodiment shown in Figs. 3A and 3B, the cooling auxiliary station 32C for applying the cooling treatment as a post-treatment to the material 5 to be treated already joined in addition to the insertion assistant station 32A and the extraction auxiliary station 32B. ), Three auxiliary stations 32A, 32B, and 32C are disposed adjacent to the main station 31.

Thus, these stations 32A, 31, 32C, and 32B are arranged in this order.

The same symbol as that used in Example 2 represents the same member.

Since the main station 31, the insertion auxiliary station 32A and the extraction auxiliary station 32B are the same as those described in Embodiment 2, the structure of the cooling auxiliary station 32C will be described. The operating chamber 11C of the station 32C is only for cooling the material 5 to be treated which has already been pressurized, so the upper portion of the operating chamber 11C is closed and the lower end of the operating chamber 11C is provided with a hoist 13C. There is a movable cover 8d for opening and closing the opening 11a, and a moving member 7d provided on the upper surface of the movable member 8d, and the material 5 to which the refrigerant supply and discharge pipeline 56 is to be processed. It is installed in communication with the operating chamber (11C) to forcibly cool the refrigerant is supplied. Furthermore, since one station has been added, three sets of clamp holders 14b and 14b that can be coupled to the support member 6 to the pair of transfer members 14a and 14a of the transfer device 14 are station. The inner pitches 32a, 31b, 32b, and 32b of the common tanks 32a, 31a, 32a are arranged at the same pitch as the center pitch of ) And 32a are enclosed so that they can communicate with each other so as to be blocked from the outside.

The pressurization cycle of Example 3 is different from Example 2, which consists of inserting, pressurizing and drawing out, only consisting of a cycle of inserting, pressurizing, cooling and drawing out.

Therefore, this difference will mainly be explained.

In the state shown in FIG. 3A, in the main station 31, the movable lid is moved downward and the insertion auxiliary station (1) is moved to take out the material 5b to be processed and the material 5b to be processed is already pressurized. At 32A), the insertion operation of the new material to be treated for the next step of pressurization is completed, while the pre-pressurized material 5c to be forced-cooled in the cooling chamber 11C is taken out of the operating chamber 11c and the movable lid Assume that it is in the position shown by the downward motion of 8d.

From this state, three sets of clamp holders 14b and 14b in the conveying members 14a and 14a are connected to the stations 32A and 31 by the movement of the conveying members 14a and 14a. (32C) are formed to correspond to the supporting members 6a, 6b, 6c for the respective materials 5a, 5b, 5c to be treated, and clamp holders 14b, 14b The support members 6a, 6b and 6c are coupled to each other by rotation of the transfer members 14a and 14a, and the transfer members 14a and 14a are pitched to the right as shown in the drawing. Move one by one.

The material 5c which has already been cooled moves on the movable lid 8c of the take-off auxiliary station 32B, and the material 5b that has already been pressurized is placed on the movable lid 8d of the cooling auxiliary station 32C. And the new material 5a to be treated is moved onto the movable cover 8a of the main station 31.

Subsequently, the movable covers 8a, 8d, 3c of the main station 31, the cooling subsidiary station 32C, and the ejection subsidiary station 32B are raised, and the new material 5a to be processed is pressurized at the main station. And the material 5c to be treated which has already been pressurized and cooled in the take-off auxiliary station 32B is taken out.

On the other hand, in the cooling auxiliary station 32C, the movable cover 8d is raised to close the operation chamber 11a, whereby the operation chamber 11c is clogged so that the material 5b to be treated which is filled from the internal space 32a and already pressurized is movable. It is held in the chamber through the member 7d and the supporting member 6c.

Thus, cooling air or other refrigerant can be continuously supplied to the room through the refrigerant supply and discharge pipeline 56 to cool the material 5b to be actively processed to a predetermined temperature.

The cooling system may use either a Circulation type or a Self type and both may be used (the detailed structure is not shown).

During this period, in the insertion assistant station 32A, the new material 5 to be processed is inserted and brought back to the state of FIG. 3A.

According to the third embodiment, it is possible to complete the two cycles by integrating not only hot hydrostatic pressure for the material 5 to be treated, but also cooling treatment of the material to be treated later, depending on the material of the material to be treated.

Therefore, it is not necessary to install the separate cooling device outside the high pressure vessel 2, so that a series of cycles can be performed with high efficiency and further increase productivity.

In addition, the cooling treatment is performed by the movement of the materials in the sealed tanks 12a, 12b and the operating chamber 11c, thus maintaining the stability and uniformity of the quality and making the whole apparatus including the cooling apparatus compact. have.

Example 4

In the fourth embodiment shown in FIGS. 4A and 4B, the preheating process is performed as a pretreatment to the material 5 to be treated before pressurization other than the insertion aid station 32A and the extraction aid station 32B. A preheating auxiliary station 32D for this purpose is added so that the three auxiliary stations 32A, 32B, 32D are disposed adjacent to the main station 31.

The same member number as used in the third embodiment denotes the same member as the member shown in the third embodiment.

The main station 31, the insertion auxiliary station 32A and the extraction auxiliary station are the same as those in the third embodiment, and therefore only the configuration of the preheating auxiliary station 32D will be described.

In the preheating auxiliary station, the operating chamber 11D is installed to preheat the material 5 to be treated before pressurization, so that the upper part of the operating chamber 11D is closed and the preheater 4a is installed inside through the thermoelectric layer 3a. These are of the same kind as the heat insulating layer 3 and the heater 4 in the high pressure vessel 2 of the main station 31.

Another configuration of the fourth embodiment is the movable cover 8e and the transfer member provided on the upper surface of the movable cover 8e, which can open and close the opening 11a at the lower end of the operating chamber 11D by the elevating device 13D. Similar to that of the third embodiment except that 7e is provided.

The pressurization cycle of the fourth embodiment is an insert, preheat, pressurize and takeout cycle slightly different from the insert, pressurize, cool and take out cycle of the third embodiment.

Therefore, these differences will be mainly described.

The state shown in FIG. 4A shows that the material 5c to be processed at the main station 31 has already been pressed and the movable lid 8a is moved downward to take out the material 5c to be processed from the container 2, The insertion process of the new material sa to be processed for the next pressurization is completed in the insertion auxiliary station 32A, and the operating chamber 11D is provided in the preheating auxiliary station 32D, (not shown but provided with an energy supply device). It is assumed that the material 5b to be treated to be pressed after being already preheated at is taken out from the operating chamber 11D by the downward motion of the movable cover 8e.

Therefore, from this state, the three sets of clamp holders 14b and 14b of the conveying members 14a and 14a are treated with the materials 5a and (3) respectively treated by the stations 32A, 32D and 31, respectively. 5b) and (5c) are made to match the support members 6a, 6b, 6c, and the clamp holders 14b, 14b are moved by the movement of the transfer members 14a, 14a. 6a), 6b, and 6c are engaged to rotate the conveying members 14a, 14a and the conveying members 14a, 14a move one pitch to the right as shown in the figure.

Thus, the material 5c that has already been pressurized goes to the movable cover 8c of the take-off auxiliary station 32B and the material that has already been pressurized goes to the movable cover 8a of the main station 31 and then The material 5a to be pressurized goes to the movable lid 8e of the preheating auxiliary station 32D.

Eventually the movable lids 8e, 8a, 8c of the preheating subsidiary station 32D, the main station 31 and the take-off subsidiary station 32B move upwards so that the material 5b to be preheated at the main station 31 is preheated. ) Is pressurized and the material 5c to be treated which has already been pressurized in the take-off auxiliary station 32B is taken out via the operating chamber 11B.

In the preheating station 32D, the movable cover 8e moves upward to close the opening 11a of the operating chamber 11D so that the operating chamber 11D is closed to be independently blocked from the internal space 32a, and to be processed. Preheating required for the material 5a is performed by the preheater 4a.

Also in this case, the preheater can be used in which the atmosphere as a preheater is protected so that oxidation is promoted at high temperatures. In the meantime, in the insertion assistant station 32A, the insertion process of the new material to be processed is performed.

Therefore, pressurization is completed in the main station, preheating is completed in the preheating auxiliary station 32D, and the insertion process is completed in the insertion auxiliary station 32A, and then the movable lids 8a, 8b, 8e are lowered. It moves to and it returns to state 4a again.

According to the fourth embodiment, the HIP for the material 5 to be treated as well as the preheating operation for the material to be treated which is required prior to the pressurization cycle can be integrated and completed. Thus, there is no need to install a separate preheater outside the high pressure vessel and a series of cycles can be run at higher efficiency to further increase productivity.

In addition, all devices, including preheating, can be preheated in the same atmosphere as in a high pressure vessel and the transfer is carried out in a closed tank, ensuring effective, uniform and stable preheating and shortening the heating time in the high pressure vessel (2). Can be designed compact.

Example 5

In the fifth embodiment shown in Figs. 5A and 5B, four auxiliary stations 32A, 32B, 32C, and 32D are disposed adjacent to the main station 31, and The cooling auxiliary station 32C and the preheating auxiliary station 32D of the fourth embodiment are sequentially integrated in the pressurization cycle. Therefore, the insertion auxiliary station 32A, the preheating auxiliary station 32D, the main station 31, the cooling auxiliary station 32C, and the take-out auxiliary station 32B are arranged in this order.

The same reference numerals as used in the above embodiments refer to the same members as shown. The configurations of the stations 31, 32A, 32B, 32C, and 32D are exactly the same as those of the above-described embodiment, and thus description thereof is omitted.

Needless to say, the closed tanks 12a, 12b are normally shut off from the outside at all stations and the inner space is covered in communication, supporting the material 5 to be treated at the conveying members 14a, 14a. Four sets of clamp holders 14b, 14b, 14b, which can engage with the member 6, are provided as shown in FIG. 5B.

The pressurization cycle of the fifth embodiment is a cycle of inserting, preheating, pressurizing, cooling and taking out. The operation at the preheating and cooling stations is well illustrated in the fourth embodiment, where only the essential part of the series of cycles is already pressurized with the material 5c to be processed at the main station 31 in FIGS. 5a and 5a. Cooling of the already pressurized material 5d to be taken out of the container 2 to move the material down to the position shown and to the next material 5c to be processed in the cooling auxiliary station 32C is followed. Preheating of the material 5b to be processed to be pressed at the preheating auxiliary station 32D is completed, and then insertion of the material 5a to be processed to be molded at the insertion auxiliary station 32A is completed.

Therefore, in this state, four sets of clamp holders 14b and 14b of the conveying members 14a and 14a are supported by the supporting members of the materials 5a, 5b, 5c and 5d. 6a), 6b, 6c, and 6d are engaged with each other and moved to the right in the drawing by one pitch by the conveying members 14a and 14a, the already cooled material 5d to be processed is taken out. In order to pressurize the material 5c which has already been pressurized to the station 32B to the cooling auxiliary station 32C, the preheated material 5b which is preheated to the next main station 31 is newly inserted to pressurize. The material 5a to be treated is respectively conveyed to the preheating auxiliary station.

Therefore, a series of pressurization cycles of insertion, preheating, pressurization, cooling, and take-out are repeated in a totally automated manner, so that the already-pressurized material 5c which has already been pressurized in the take-out station 32C of the already-cooled material 5d to be processed Cooling, pressurization of the material 5b to be preheated already in the station 31, preheating of the material to be newly inserted in the station 32D and insertion of new material to be processed in the station 32A are all performed. Can be.

According to the fifth embodiment, in the HIP operation on the material 5 to be treated, a series of operations including insertion and preheating required before pressurization and cooling and take-out necessary after pressurization are pressurized in the high pressure vessel 2 with very high efficiency. After this is completed, the already pressurized material 5 to be treated is carried out completely automatically without waiting and loss time so that the material 5 can be immediately discharged out of the container.

In addition, the movement of the material 5 to be treated at all stages takes place in the closed tanks 12a and 12b, so that the treatment process can be carried out under a uniform and stabilized ambient environment, thus improving productivity and quality. In addition, the compact design of the device can be easily achieved.

In the above-described embodiment, the openings 2a, 11a of the high pressure vessel 2 and the operating chamber 11 are located at the lower ends while the openings 2a, 11a can be inverted to the positions of these openings. Note that the same effect can be achieved by placing it at the top end.

In addition, although the vertical type is used in the embodiment, the horizontal type may be used, and the circular type annular structure may be used in the embodiment although the sequential arrangement is adopted. The pretreatment and posttreatment to be applied to the material 5 to be treated before or after pressurization also consists of preheating and cooling operations, and heating and cooling can be carried out in parallel with a plurality of identical auxiliary stations.

The HIP device according to the high pressure vessel according to the present invention is firstly excellent in that it can achieve industrial mass production. 6 and 7 are graphs showing the required operating time of the conventional and the present invention according to the processing method.

In FIG. 7 showing the prior art, the center coordinates indicate pressure and temperature, the abscissa indicates time, the solid line indicates the pressure curve, and the dotted line indicates the temperature curve. According to the prior art, it takes about 3 hours to raise the temperature and pressure to a predetermined value in the high pressure vessel (2).

The holding time for pressurizing at this pressure and temperature is approximately 1 hour. It takes about 10 hours to take out from the container and lower the temperature to the oxidation prevention temperature (about 300 degreeC) of a heater as mentioned above. The pressurized material is taken out of the container 2 after the sum of the above times has elapsed, and thus the productivity is extremely low, and the time taken by the same container is increased so that repeated use is impossible.

On the other hand, FIG. 6a according to the present invention shows a state in which the heater is turned off after processing in the above-described first embodiment, FIG. 6b shows a state in which the heater is on, and FIG. The state in which the heater is turned off after the processing in the above-described embodiments 2 and 3, the state of FIG. 6d shows the state in which the heater is on, and the state of FIG. 6e relates to the embodiments 4 and 5 described above. In Figures 6a, 6b, 6c, 6d and 6e, the left half represents the first time required, and the right half represents the subsequent time required. In the first embodiment it takes about three hours to initially increase the temperature and time and about one hour to maintain pressurization.

However, when the pressurized material is taken out of the container when the heater is turned off, it can be taken out immediately by only lowering the pressure, so that the time is reduced to about 1 hour. It takes two hours because one auxiliary station is used to insert and withdraw the treated material.

In the case where the increase in temperature may be rapid, the time for increasing the temperature and pressure is reduced by about 1 hour depending on the nature of the treated material if the heater remains ON continuously in FIG. 6B. In the above-described embodiments 2 to 5, the auxiliary station used independently is used and thus the time required for the insertion and withdrawal of the material to be treated is reduced by about half an hour and after the second time has elapsed, the temperature in the high pressure vessel 2 And the time for increasing the pressure is reduced to about 2 hours depending on the holding temperature when the heater is off and to about 1 hour when the heater is continuously on. Since the material to be treated in FIG. 6E is preheated, a pressurization time of about half an hour is sufficient.

When the pressurized processed material 5 is taken out from the high pressure vessel 2, unlike the conventional method, no waiting time is required, so that the high pressure vessel 2 can be repeatedly used for a short time and the pressurization cycle can be progressed with high efficiency. Increase significantly.

This effect is because the internal space of the station is blocked from the outside by a common hermetic tank and maintained in the same atmosphere as the interior of the high-pressure container 2.

At the same time, the material 5 to be treated can be transported and processed internally so that no damage or quality change of the material to be treated occurs, which is effective in maintaining a stable and high reliable quality. In addition, since the interior of the operating chamber in the auxiliary station is in communication with the interior of the tank and is blocked by the movable lid, the pre and post treatment can be easily performed independently under an appropriate atmosphere, thereby obtaining the above advantages.

In addition, unlike the conventional apparatus that the insertion means and the ejection means are exposed to the outside adjacent to the high-pressure vessel and the cooling and preheating means are located far away and lacking in unity including many operation processes, the present invention is capable of main and auxiliary stations. It is arranged adjacent to each other as a short distance and the inner space is covered by a closed tank, the drive means are arranged collectively so that the apparatus of the present invention can be designed compact.

The device of the present invention has a great advantage in being able to industrially mass-produce HIP products by high pressure vessels.

In the invention (II), the main station 431, (FIG. 10) and the auxiliary station 432, (FIG. 9) are the same in structure as the above-described invention (I) and will not be described. Stations 431 and 432 are arranged in the same circumference as shown in FIG.

Auxiliary station 432 is provided with a rotatable table 415 in preparation for transporting material 405 to be processed towards main station 431.

The annular hermetic tank 412 composed of the upper tank 412a and the lower tank 412b is installed to block and surround the inner space of the main station, the auxiliary station 431, 432 while communicating with the inner space.

Movable lids 408a and 408b are positioned on the turntable 415 and overlap on the member 406a, in which case the elevator 409 moves the turntable 415 if the material 405 to be treated has not yet been pressed. It extends through the hole 415a formed in the inside, moves the movable cover 408a upward, and closes the opening 402a of the high pressure container 402.

Here, the material 405 to be treated enters the container 402 by the supporting and moving member 406a and is subjected to hot hydrostatic pressure under predetermined conditions of high pressure and high temperature.

If the material 405 to be processed has already been pressed, the turntable 415 is rotated to transfer the already processed material 405 to the auxiliary station 432.

[Example of Invention (II)]

Example 1

8 to 12 show a first embodiment of the invention (II), which is similar to the invention (I), and therefore only the differences between them will be described. The movable lid 408a is positioned on the rotary table 415 so that the support and moving member 406a of the material 405 to be processed is mounted on the upper surface of the movable lid 408a.

As shown in FIG. 8, the main station 431 and the auxiliary station 432 are arranged on the same circumference. The movable cover 408a is located on the rotary table 415 corresponding to the auxiliary station 432, and the movable cover 408b having the movable member 406b of the material 405 to be processed is the upper surface of the table 415. Installed in, the internal space communicating with the internal space of the main station 431 is installed between the operation chamber 411 and the lifting device 413 and the internal space is communicated through the annular sealed tank 412.

The closed tank 412 for enclosing the internal spaces of the main station 431 and the auxiliary station 432 from the outside in common is annular in the form of a combination of the upper and lower tanks 412a and 412b.

The effects obtained by the invention (II) are shown in FIGS. 23A to 23D as compared with those of the prior art shown in FIG.

However, these effects are the same as those described in the invention (I) for FIGS. 6 and 7, and thus detailed description thereof will be omitted.

However, in the invention (II), since the closed tank is annular and the rotary table is installed in the closed tank and the material to be processed or the like is transferred to each station, their transfer is smooth and stabilized so that the material to be treated is falling. Is prevented.

Invention (III)

According to the invention (III), as shown in FIGS. 25, 26, 27 and 28, a plurality of operating stations according to the operating steps to be applied to the material 805 to be treated, ie the first station I in FIG. The second station (II) and the third station (III) are continuously arranged in parallel on one side (top in FIG. 25) of the closed tank 815 forming the closed working space 815a.

The first station (I) is a station for inserting the material to be treated and is a station body including an operating chamber 811 having an open top cover 812 installed at an upper end thereof, and a lower portion of the operating chamber 811 An entrance 811a of 805 is formed and the entrance is opened to the working space 815a.

The second station II is a forming station for HIP treatment of the material 805 to be treated, which is the station body in which the known high pressure vessel 802 of the HIP apparatus is included.

The container 802 has a heater 804 installed therein through a heat insulating layer 803a in a known manner, and is not shown, but a high pressure gas generator, a vacuum device, a container cooler, and an energy supply device for the heater are attached. .

The top cover 809 is installed through the pressing frame 801 at the upper end of the container 802, and the entrance and exit 802a of the material 805 to be treated is the working space 815a as the operating room 811 of the first station. Open to communicate with).

The third station (III) is a take-out station for taking out the material 805 to be heated and pressurized in the high pressure vessel of the second station (II) to the outside, and the take-out station opens and closes the top cover 812 at its upper end. It is a station body including an operating chamber 811 is installed, the operating chamber 811 has an entrance of the material 805 to be processed at the lower end and the entrance 811a is open to communicate with the operation chamber 815a. .

In this way a number of operating stations (I, II, III, three stations of the illustrated embodiment, two or more stations can be installed as required) are treated on one side of the sealed tank 815 forming the sealed space 815a. The doors 811a, 802a, 811a of the material to be processed at the station are opened to communicate with the enclosed space 811a in parallel in the order of the operating steps applied to the material 805 to be moved, and move to the next step. The working space to be obtained can be obtained at the end of each stage in isolation from the outside and extremely dense under the conditions of the collective operating stage.

Therefore, it is possible to obtain the shortest transfer path of the material to be processed formed of the raw material which is sensitive to atmospheric pressure and temperature, thereby reducing and saving time and effort required for the transfer.

Furthermore, the opening and closing lids 808, which can completely close the entrances 811a, 802a, and 811a, respectively, are shown in FIG. 25 at the other side (bottom of 25 degrees) of the closed tank 815 corresponding to the side where the station is installed. It is supported on a base sheet 807 or the like, which can place or support the material to be processed by the receiving base 806 at the same location as the center of the entrance.

The cover is installed to move up and down and open and close by the elevating device 801.

A pair of feed shafts 823, 823 extending through the closed tank 815 along one end of the opening and closing cover is axially installed toward the opening and closing cover 808 as shown in the 25, 26, 28 degrees have.

The conveying device is installed to be able to rotate around the shaft.

Of detachable gripping pawls 826,826, which can be fixed and released by rotating about the axis normal or vice versa, so that the material 805 to be treated on each base sheet 807 of the opening and closing cover 808 is fixed. The receiving base 806 has an opening and closing cover in the first and second stations (I, II) except for the third station (III) of the take-out station of the material to be processed, as clearly seen in FIGS. 25 and 28. 808 is installed opposite.

By doing so, automatic transfer of the material to be processed between the stations I, II and III can be performed in the closed operating space 815a.

More specifically, in the state shown in FIGS. 25 and 26, pressurization of the material to be processed in the high pressure vessel 802 in the second station II is finished, and the entrance 802a of the container 802 is closed during pressurization. The opening and closing cover 8 supporting the material to be processed through the base sheet 807 and the receiving base 806 is moved downward by the elevating device 810, and at the same time, the opening and closing top cover 812 is opened at the first station. The new material to be processed with the receiving base 806 is inserted into the base sheet 807, and the opening and closing cover 808 is likewise moved down by the elevator 810. In this state, the shaft 823 on the right side of FIG. 28 rotates clockwise while the shaft 823 on the left side of the figure rotates counterclockwise, and the pair of opposed grip poles 826, 826 and 826, 826 move downward. It rotates over one opening and closing cover 808 to hold the receiving bases of the material 805 and 805 to be processed in a symmetrical position.

The receiving base 806 may thus also be accommodated such that the lower surface can leave a smaller gap than the upper surface of the base seats 807. Next, both feed shafts 823 move straight toward the third station III on the right side of the drawing, one pitch in the state described, so that the material to be treated that has already been pressurized with the receiving base of the third station III. Moving toward the opening and closing cover 808, the new material to be processed inserted and set in the first station (I) is moved to a position facing the opening and closing cover 808 of the second station (II). In this position, both feed shafts 823, 823 stop and if both shafts 823 rotate in the opposite direction as described above, the sets of poles 826, 826 and 826, 826 are both released from the receiving bases 806 and 806, and the material to be treated ( 805 and 805 are supported by the base sheets 807 and 807 of the opening and closing cover 808 at the station II and are released. Thus, if the opening and closing cover 808 is raised and closed by the elevating devices 810 and 810, respectively, the second station II, the entrance and the entrance of the third station III, the material 805 that has already been pressurized The next new material 805 to be transported into the operating chamber 8911 isolated from the enclosed space 815a and to be processed is set sealed in the high pressure vessel 802 and is already pressurized at the third station III. The material 805 to be taken out is taken out, and pressurization under ultrahigh pressure is performed in the second station II. At that time both feed shafts 823, 823 have already been pressed and then returned to the position shown in FIG. 25 for the duration of the process described above to wait for the take-out of the material to be treated and the new material 805 to be treated.

As described above, operation in the operating stations I, II and III, entry and exit of the material 805 to be processed into and out of the station and movement between the stations are vertically movable opening and closing lids 808 and the feed shaft. It is fully automated by 823 and is repeated in closed tank 815a. In addition, since the operation is performed in the enclosed operating space 815a, if the space is maintained under a desired atmosphere, the material to be treated sensitive to changes in thermal conditions or factors such as being scattered or changing in quality under ambient atmosphere ( 805) and other members of the device can be handled without inconvenience and the quick, easy and safe operation is possible by the shortest transport distance isolated from the outside.

[Example of Invention (III)]

Example 1

The embodiment shown in Figs. 25 to 30 shows an example of a three-station type in which the conveying apparatus of the invention (III) is applied to the HIP apparatus.

Here, the first station (I) serves as an insertion station of the material 805 to be treated, and the second station (II) is a forming station for pressurizing the material to be processed into bricks by the ultra high pressure of the HIP, and the third station (III) is the take-out station of material 805 to be treated which has already been pressurized.

The first and third stations I and III are constituted by cylindrical operation chambers 811 having upper and lower portions opened, and the upper opening is opened and closed by an opening and closing cover 812.

The opening and closing structure can be freely designed.

In the illustrated embodiment, as shown in FIGS. 25, 29, and 30 degrees, the pivot shaft 818 is installed in the closed tank 815a of the operating chamber 811 and supports one end of the opening and closing cover 812. ) Is rotatably inserted into the guide sleeve 817, which is held through the installation member 816, and the piston rod 819a of the drive cylinder 819 is connected to the lower end of the pivot shaft 818. And a sliding pin 820, which is provided on one portion around the pivot shaft 818, is slidably coupled to the cam groove 817a formed around the guide sleeve 817 to form a piston of the drive cylinder 819. The rod 819a moves up and down to rotate, and the pivot shaft 818 moves vertically by the automatic opening / closing cam groove 817a and the sliding pin 820.

Both stations (I, II) have a pipeline 855 connected to the vacuum pump 851 to be in a vacuum state as shown in FIG. 25, and the atmosphere in the operating chamber 811 needs to be vacuum, active or inert gas atmosphere. It is designed to be placed inside.

The required gas is supplied from the gas cylinder 852 through the pressure reducing valve 853 and the pipeline 854.

The closed tank 815 is configured of a rectangular tank formed of an airtight member.

On the closed tank 815, the first, second and third stations I, II and III are arranged in this order with their centers spaced at equal intervals.

The operating chamber 811, the high pressure vessel 802 and the lower part of the operating chamber 811 in the stations I, II and III are fixed to the upper surface of the tank 815.

The entrances 811a, 802a, 811a at the bottom communicate with the openings in the closed operating space 815a of the tank 815. In addition, in the working space 815a of the tank 815, the pipeline 855 from each vacuum pump 851 is connected to the pressure reducing valve 853 and the pipeline 9856 from the gas cylinder 852 so that the necessary vacuum atmosphere or activity is achieved. Inert gas atmosphere can be formed.

At positions corresponding to the entrances 811a, 802a, and 811a of the material 805 to be treated in the stations I, II, and III, the base sheets 830 are provided below the tank 815, and the lifting device The opening and closing cover 808, which is connected to the rod 810b installed at the lower side of the base sheet 830 and the driving cylinder 810a and the piston rod 810b, which is 810, may move up and down on the upper surface of the base sheet 810. And a base sheet 807 on which the receiving base 806 holding the material 805 to be processed is located and supported is formed on the upper surface of the lid 808.

The driving cylinder 810a is connected to the opening / closing cover 808 to the elevating device 810 of the second station II, and the piston rod 810b is fixed to endure the ultra high pressure in the high pressure container 802. have.

A pair of feed shafts 823 and 823 for transferring material between stations are arranged parallel to each other by bearings 831 so that the feed shafts extending through the tank 815 are spaced apart so as not to obstruct the opening and closing cover 808. Along the opening and closing cover 808 is installed to be able to stretch in the axial direction and to rotate the circumference of the axis.

The grip poles 826, which can be engaged and disengaged by rotation in the feed shaft 823, are the station (I, II) except the last station (III) of the station (I, II) except the last station (III). The material 805 to be fixedly installed and treated with respect to the flange 806a of the receiving base 806 of the material to be processed at the half of the opening and closing cover 808 may be supported and transported through the receiving base 806. A mechanism can be freely designed to allow the axial stretching movement of the feed shaft 823 and the rotational movement in opposite directions about the axis. In the illustrated embodiment, each end of the feed shaft 823 extending out of the tank is formed of a splined portion as shown in FIGS. 25-28, above the piston rod 821a of the transfer cylinder 821 installed on the base 832. It is rotatably connected to and supported on the supported crosshead 822 and the spline sleeve 829 is movably coupled to the base 832 by bearings 828 and 828. The pinion 825 is mounted on the sleeve 829 and the rack portions 824a and 824a formed on both sides of the rack 824 supported by the piston rod 827a of the rotary cylinder 827 installed on the base 832. (824) are engaged.

Both feed shafts 823 can be rotatably moved simultaneously in the axial direction by the transfer cylinder 821, and the pair of pinions 825, 825 are moved up and down on the rack 824 by the rotation cylinder 827.

Rotate in opposite directions, and at the same time, axes 823 rotate around the axis. The spline bond described above can be replaced with a key bond structure.

In FIG. 25, the engaging portion 810c is positioned around the drive cylinder 810a of the elevating device 810 of the opening and closing cover 808 to open and close the entrance and exit 802a of the high pressure container 802 of the second station II. This is because the clamping device 814 installed perpendicular to the engaging portion 810c engages with the pressing frame 801 to assure the closed position when the cylinder is moved up so that the cover 808 takes the closed position.

According to the above embodiment, the interior of the working space 815a of the closed tank 815 is placed in the same vacuum or active, inert gas atmosphere as the high pressure vessel 802 in the second station II, and the first station. The opening and closing cover 808 in (I) is moved to block the operating chamber 11 from the operating space 815a to open the opening and closing cover 812, and to open and close the material 805 to be processed together with the receiving base 806. It is positioned on the base sheet 807 of 808. The opening and closing cover 808 then moves down with the material to be treated to rotate the grippool 826 in the pair of feed shafts 823 to engage the flange 806a of the receiving base 806.

When the feed shaft 823 is moved by one pitch, the feed shaft 823 is conveyed to the position of the opening / closing cover 8 of the second station II. The gripfools 826 are then disengaged to support the material 805 receiving base 806 to be processed on the basesheet 807 of the opening and closing cover 808 of the second station II.

The lid 808 then moves up to close the entrance 802a of the high pressure vessel 802 and the material 805 to be treated can be filled in the container 802 together with the receiving base 806. Thus, while hot hydrostatic pressure is applied to the material 805 to be processed at the second station II, the feed shafts 823 contract and the opening and closing cover 808 moves up at the first station to open and close the door of the operating chamber 811. The new material 805 to be processed may be charged by closing 811a and opening and closing cover 812.

At the end of the pressing operation in the second station II, the opening and closing cover 808 immediately moves down to move the already pressurized material 805 to be processed to the position of the feed shaft as shown in FIG.

Similarly, in the first station I, the opening and closing cover 808 moves down to move the new material 805 to be processed to the position of the feed shaft, and at the same time, the grippools 826 of the feed shaft 823 are rotated and processed. Hold the receiving base 606 of the material 805 to be. At this time, the feed shafts 823 can move by one pitch so that the material 805 to be processed is moved to the position of the opening and closing cover 808 of the second station (II) and the material 805 to be processed being pressurized is moved to the third. Move to the opening and closing cover 808 position of the station (III). Accordingly, in this position, the grippools 826 are released and at the second station II, the insertion and setting operation of the new material 805 to be processed into the high pressure vessel 802 is performed. Then, a work is performed to move the material 805 to be processed, which has already been pressurized in the third station (III), into the operating chamber 811, all of which are closed by the door 802a by the upward movement of the opening and closing cover 808. Is performed with.

The already pressurized material to be processed 805 moved into the operating chamber 811 separated from the operating space 815a in the third station III opens and opens the upper opening and closing cover 812. During this time, the pair of feed shafts 823 return to their original positions and the insertion operation of the new material 805 to be processed at the first station I can proceed simultaneously.

A series of feed movements are performed by the movement of the grippool 826 through the upward movement of the opening / closing cover 808 at the stations I, II, and III, by stretching movement as the axial direction of the pair of feed shafts 823, And it can be automatically performed by the rotational movement about the axis of the opening and closing cover 808 in the lower position. In addition, such operation can be quickly achieved by the vertical and horizontal movements of the shortest feed path and the small rotational movement about the axis in the workspace 815a which is not affected by external air pressure. Although the heater 804 is energized at a high temperature, it is only possible for this HIP device to create a non-oxidative atmosphere that is isolated from the outside, so that it is already pressurized upon insertion and withdrawal of the material to be treated into the high pressure vessel. Can be taken out immediately without having to wait for cooling of the material 805. At the same time, it is possible to make the press cycle extremely short and to transport the material to be safely processed. Therefore, the overall productivity is improved.

Example 2

The second embodiment of the invention (III) shown in Figs. 31 and 32 is a two-station type.

Since this second embodiment is similar to the first embodiment described above, only the differences between them will be described.

The first station I serves as an insertion and withdrawal station for the material 805 to be treated and the second station II serves as a pressure stain by the high pressure vessel 802. Thus, the first station I also acts as a final station, so that this final station contains only one set of grippools 826 of the feed shaft 823 of one phase.

In this embodiment, the opening and closing cover 812 at the top of the operating chamber 811 in the first station (I) can be opened and closed manually rather than automatically opening and closing.

In a mechanism for axial movement and rotation of the pair of feed shafts 823, a rotating cylinder 827 of the rack 824 is supported on the crosshead 822 by a support member 833. In addition, pinions 825 and 826 are installed directly on shaft 823 to engage rack 824 without the need for installing a sprocket on feed shaft 823.

The conveying motion in this case is similar to the conveying motion of the first embodiment except that, at the first station I, the material to be treated that has already been pressurized is taken out and a new material to be processed is inserted.

The format of the first embodiment can be easily changed to the two-station format without needing to be explained.

This is true of all the plural stations described below.

Example 3

The third embodiment shown in FIG. 33 is a four-station format. The first station (I) serves as an insertion station for the new material 805 to be treated, the second station (II) serves as a pressurized station by the high pressure vessel 802, and the third station (III) A station that immediately cools the material to be processed pressurized in two stations to facilitate post-processing.

The operating chamber 811 of the station III is blocked at the top thereof, and an entrance 811a is formed only at the bottom thereof, and a refrigerant supply and discharge line 857 is connected to the operating chamber 811. Thus, the material 805 that has already been pressurized is taken out of the second station (II) and moved by the feed shaft 823 to the position of the opening and closing cover 808 of the third station (III), and then the cover 808 is moved upward. It moves to isolate the operating chamber 811 from the operating space 815a and holds the material to be treated in the room to rapidly and actively cool the material to be treated. The material to be cooled is transferred to the next fourth station IV, that is, the take-out station.

By employing this type, subsequent cooling processes required for the material 805 to be treated can be integrated into a series of transfer cycles, eliminating the need for external cooling equipment, resulting in a stable and even cooling effect and increased productivity of the press cycle. Can be. In this case, three sets of grip poles provided on the pair of feed shafts 823 are opposite to the opening and closing lid positions of the stations I, II and III except for the opening and closing lid 808 position of the last fourth station IV. Is installed.

Example 4

The embodiment shown in FIG. 34 is also in a four-station format, where a station is provided for preheating the material to be treated as a process prior to pressurization.

The first station I is the insertion station of the material to be treated, the second station II is the preheating station, the third station III is the pressurizing station, and the fourth station IV is the take-out station. In the second station (II) for preheating, the upper part of the operating chamber 11 is blocked so that an entrance 811a is formed only in the lower part, and the operating chamber 811 is provided with a preheater 804a through a thermal insulation layer 803a therein. It is installed.

This preheating structure is almost the same as that of the high pressure vessel 802.
