Description

Detailed Description of the Invention (Industrial Application Field) The present invention involves charging a material to be processed, such as a pre-shaped metal powder, into a high-pressure container equipped with a heater.
By combining the ultra-high pressure increase of the fluid or gaseous medium sealed in the container and the heating by the heater, it is possible to improve the efficiency of the actual production equipment as a hot isostatic pressing device for press forming the material to be processed. related to what was done.

(Prior art) A material to be processed, such as a pre-shaped metal powder, is charged into a high-pressure container equipped with a heater and in which the interior is kept in a vacuum state or an active or inert gas atmosphere.
A hot isostatic pressing device that pressure-forms a processed material into a block shape by increasing the pressure of a fluid or gas medium sealed in a container to an ultra-high pressure is an ultra-high-pressure press forming technology that goes without saying as an example of a so-called HIP device. It is well known as one of the As is well known, the actual production equipment for such a device is mainly a high-pressure container with a sealed structure, a part of which can be opened and closed by a lid, and which is isolated from the outside world by closing the lid. The means for opening and closing the lid and the means for carrying in and out the material to be processed into and out of the container are merely exposed to the outside world outside the container, and require considerable handling operations.

(Problems to be Solved by the Invention) As heaters used in high-pressure vessels in the prior art, heaters using energized heating wires made of molybdenum-based or graphite-based materials are commonly used in relatively high-temperature ranges. However, such heaters oxidize (consume) when exposed to outside air at high temperatures, so when taking out the processed material that has been sealed and pressure-molded in a high-pressure container from the container, it is necessary to take a certain amount of heat after releasing the high temperature and high pressure. It is necessary to wait until it has cooled before taking it out, which of course increases the press cycle time and impedes productivity improvement. In addition, in the pre-HIP process, the material to be processed must be loaded into the equipment at room temperature and pressure, and then the temperature and pressure must be increased, which lengthens the press cycle and is a factor that impedes productivity. be.

In addition, molybdenum-based and graphite-based heaters oxidize in high temperature atmosphere, so there are some that require a non-oxidizing atmosphere, and some that require a special atmosphere because the object to be processed cannot be taken out in the air at high temperatures.

The present invention allows the material to be processed to be inserted at a high temperature while the heater is energized, regardless of the opening/closing operation of one end of the HIP device. This makes it possible to take it out of the container immediately without having to wait for the temperature to drop, shortening the press cycle time and greatly improving productivity in hot isostatic pressing equipment using this type of high-pressure container. It is something.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above-mentioned object is to provide a high-pressure container for hot isostatic pressing having at least one end that can be opened functionally. The main station is equipped with a movable lid member for opening and closing one open end of the container, and a member attached to the movable lid member for moving the material to be processed into and out of the container, and one end of the movable lid member is open and the material to be processed is moved into and out of the container. A working chamber for inserting and/or taking out materials, a movable lid member for opening and closing one open end of the working chamber, and a member for allowing materials to be processed into the room attached to the movable lid member. An auxiliary station for insertion and extraction is provided, the main and auxiliary stations are arranged on the same circumferential surface, the internal spaces of both stations are commonly isolated from the outside world, and are kept in a vacuum state or a necessary gas atmosphere, A loop-shaped sealed tank is provided that communicates with and surrounds each internal space, and a rotary table is provided inside the loop of the sealed tank so as to be freely rotatable on a horizontal plane. Each of the movable lid members is placed thereon, and an elevating device is provided that allows each of the movable lid members to be raised and lowered from the rotary table, and insertion/removal holes of the elevating device are formed in the rotary table.

(Function) According to the technical means of the present invention, as shown in FIG. 3, the high-pressure container 2 with one end (lower end in the example shown) open is fixedly installed on the upper part of the press frame 1, In other words, the material to be treated 5 is placed in the container 2.
A movable lid member 8a that opens and closes the opening 2a for entry and exit into the interior of the press frame 1 is disposed at the lower part of the press frame 1 via an elevating device 9 so that it can be raised and lowered toward the opening 2a. The main station 31 is provided with an inlet/outlet member 6 a for moving the processing material 5 into and out of the container 2 .

Further, as shown in FIG. 2, one end (lower end in the illustrated example) is open as an opening 11a, and the other end (upper end in the illustrated example) is an opening/closing lid 10 (the opening/closing means for the lid is automatic,
A working chamber 11 (without manual operation) and a movable lid member 8b that seals the opening 11a in an openable and closable manner are provided so as to be movable up and down toward the opening 11a by an elevating device 13. The auxiliary station 32 is provided with entry/exit members 6b on the upper surface thereof for moving the material 5 into and out of the working chamber 11.

Each of the stations 31 and 32 is a first station.
As shown in the figure, they are arranged on the same circumference.

In the main station 31, the material to be processed 5 is loaded into the container 2 through the in/out member 6a provided on the upper surface of the movable lid member 8a, and the movable lid member 8a is sealed against the opening 2a of the high pressure container 2. can enter,
Therefore, in this state, the heater 4 provided in the container 2 via the heat insulating layer 3 is heated, and although not shown, the fluid or gas medium sealed in the container 2 is increased to an ultra-high pressure as is known. Further, the material to be processed 5 can be formed by hot isostatic pressing in a vacuum state or an active or inert gas atmosphere inside the container 2.

Furthermore, although not shown in the drawings, it is also conventional technology that the HIP apparatus main body is attached with a high-pressure gas generator, a vacuum device, a container cooling device, a heater energizing device, and the like.

On the other hand, at the auxiliary station 32,
By making the movable lid member 8b, which has an inlet/outlet member 6b for the material to be processed 5 attached to its upper surface, openable and closable to the opening 11a of the working chamber 11, the working chamber 11 can be used to transfer the material to be processed before pressure forming. Necessary processing operations can be freely performed on the material 5 or the material 5 to be processed after pressure molding.

For example, by closing the movable lid member 8b to the opening 11a, the opening/closing lid 10 of the working chamber 11 is opened and connected to the atmosphere, and the material 5 to be processed before molding is charged into the chamber and taken in and out. By placing it on the member 6b and closing the opening/closing lid 10, the work chamber 11 is opened.
After the tank is independently sealed and the atmosphere is the same as that of the sealed tank 12, the movable lid member 8b is lowered, and preparation work for transporting the material to be processed from the rotary table 15 to the main station 31 side is performed, and vice versa. With the molded workpiece 5 placed on the in/out member 6b of the movable lid member 8b, the movable lid member 8b is raised to close the opening 11a, and the workpiece 5 is brought into the working chamber 11. After the gas is delivered and the atmosphere is changed to the same atmosphere as the inside of the sealed tank 12, it can be taken out to the outside world by opening the lid 10. Therefore, at the auxiliary station, the material to be processed is loaded, taken out, and the material to be processed 5 is
Various operations such as pre-treatment and post-treatment required before and after the molding process can be performed independently, and furthermore, can be performed in parallel with the pressure molding operation at the main station 31.

Furthermore, an upper tank 12a is a loop-shaped sealed tank 12 that isolates each internal space of the main and auxiliary stations 31 and 32 from the outside world and surrounds it in a continuous manner.
and a lower tank 12b, this sealed tank 1
2 is airtightly fitted to the outside, the space between both stations 31 and 32 is cut off from the outside world, but
An integral space that communicates with each other is enclosed, and by providing a gas cylinder 51 and a vacuum pump 53 in communication with this sealed tank 12, the internal space of each station 31, 32 is kept in a vacuum state or active state in the high-pressure container 2. , the environment can be the same as the inert gas atmosphere state. The object of the present invention can be easily achieved by providing the rotary table 15 so as to be freely rotatable on a horizontal plane throughout the interior space.

That is, the movable lid member 8 is placed on the rotary table 15.
a, 8b are placed and overlapped with the inlet/outlet member 6a, and if the processed material 5 is before molding, the insertion/removal hole 15a formed in the rotary table 15
The lifting device 9 is extended through the movable lid member 8a.
By raising and closing the opening 2a of the high-pressure container 2, the material to be processed 5 is moved to the entrance/exit member 6 which also serves as a support.
The material to be processed 5 can be subjected to hot isostatic processing under predetermined processing conditions such as high pressure and high temperature. Further, if the processed material 5 is a molded material, the processed material 5 is transported to the auxiliary station 32 by rotating the rotary table 15.

Furthermore, by raising the movable lid member 8b in synchronization with the above-mentioned hot isostatic processing,
At the same time as the movable lid member 8b closes with the opening 11a of the working chamber 11, the material to be processed 5 and the in/out member 6b are closed.
is sent into the working chamber 11, and only the working chamber is made into an atmospheric atmosphere while maintaining the vacuum, live, and inert gas atmosphere in the sealed tank. Therefore, the material to be treated 5 can be taken out through the openable lid 10 regardless of the sealed tank. In particular, when inserting the processed material 5 into the high-pressure container, the sealed tank has an atmosphere that does not oxidize the heater, so the heater can be inserted while maintaining the high temperature. When taking out the high-pressure container 2, the internal space can be made to have the same atmosphere as the inside of the container 2 through the sealed tank 12, so that after the molding in the container 2 is completed, the heater oxidation prevention temperature is lowered. Since the movable lid member 8a can be lowered and opened immediately after the molding is completed without having to wait until the end of molding, and the material to be treated 5 can be taken out, the cycle time can be greatly shortened. Moreover, each station 31,3

1, the number of auxiliary stations 32 can be increased as needed, so that it can shorten the press cycle, improve efficiency, and improve productivity as actual production equipment, including all necessary pre-processing and post-processing for the processed material 5. Significant improvements can be easily achieved.

This means that it will be in the same state as shown in the figure.

(Effects of the Invention) According to the present invention, it is an excellent hot isostatic pressurizing apparatus using a conventional high-pressure vessel of this kind, as it enables industrial mass production for the first time. FIG. 17 and FIGS. 16 a to 16 d are graphs showing process-wise the required working time according to the prior art and the technical means of the present invention, respectively. FIG. 17 shows the case according to the prior art, and the vertical axis is the pressure , the horizontal axis shows time, the solid line shows the pressure curve, and the dotted line shows the temperature curve.
It takes about 3 hours to raise the temperature, and about 1 hour to hold it under pressure and temperature, and as mentioned above, to take it out of the container. Approximately 10 hours are required to lower the temperature to the oxidation prevention temperature of the heater (approximately 300°C), and the pressure-molded product is removed from the container after this time has passed, resulting in extremely low productivity.
The same container is occupied for a long time, making it impossible to use it repeatedly in a short period of time.

On the other hand, according to the present invention, FIG.
The heater is turned off after processing in the example, Figure 16b shows the heater still on, and Figure 16c shows the second and third heaters.
The heater is turned off after processing in the example, Figure 16 d shows the heater still on, and Figure 16 e shows the fourth and fifth heaters.
Examples are shown in FIGS. 16a to 16a.
As shown in the appendix to the drawing in e, the left half of the figure shows the time required for the first time, and the right half of the figure shows the time required for the second and subsequent times. Even if it takes about 1 hour to hold the pressure molding, when the heater is off, taking out the pressure molded product from the container can be done immediately by lowering the pressure, so it can be shortened to about 1 hour.
The time required for extraction is 2 hours because one auxiliary station is used for both purposes. Note that from the second time onwards, the temperature and pressure raising time is reduced to 2 hours depending on the residual temperature. Although it depends on the physical properties of the product to be processed, if rapid temperature rise is acceptable, if heater Ib is kept on, the temperature and pressure increase time is shortened to about 1 hour, which is the time required to raise the temperature of only the product to be processed. In the second to fifth embodiments, dedicated auxiliary stations are used, so the time required for inserting and removing the material to be processed is shortened to about 0.5 hours. Pressure increase will be shortened to about 2 hours depending on the residual temperature when the heater is turned off, and to about 1 hour when the heater is kept on. Furthermore, since the material to be treated is preheated, the pressurization time is only about 0.5 hours.
Best of all, taking out the pressure-formed processed material 5 from the high-pressure container 2 does not require the conventional waiting time, making it possible to proceed with a highly efficient press cycle and to repeatedly use the high-pressure container 2 for a short period of time. It is clear that productivity can be greatly improved by
This effect can be obtained by shielding the internal space of each station from the outside world with a common sealed tank and creating the same environmental atmosphere as the inside of the high-pressure vessel 2. 5 can be transported and processed within this interior, eliminating any fear of deterioration or damage to the material to be processed, and is effective in maintaining stable and reliable quality. Furthermore, since the working chamber of the auxiliary station can freely communicate with the inside of the tank and is isolated by the movable lid member, it is easy to carry out the necessary pre-treatment and post-treatment independently in an environment suitable for that purpose. Yes, this can be considered an advantage.

In addition, unlike the conventional technology, the loading means and unloading means are exposed to the outside world near the high-pressure container, and the cooling and preheating equipment is located far away, which is an inconsistent system that involves many handling operations. The equipment of the present invention has an extremely compact configuration due to the adjacent arrangement of the main and auxiliary stations at the shortest distance, the covering of the internal space with a sealed tank, and the centralized arrangement of the drive means, and the hot isostatic pressure produced by such a high-pressure vessel. This is a great advantage as it makes it possible to industrially mass-produce pressurized products.

In addition, the sealed tank has a loop shape, and a rotary table is installed in it to transport the materials to be processed at each station, so the transport is smooth and stable, and there is no chance of it falling over during transport. .
