Description

[Detailed Description of the Invention] The present invention relates to a hot isostatic pressing device, and in particular,
By fixing the lower lid and allowing the container to move up and down relative to the fixed lower lid, the main purpose is to make it easy and reliable to take in and out materials, and to facilitate monitoring. .

Hot isostatic pressing equipment is known that produces products by molding and sintering powder all at once in a high-pressure, high-temperature gas atmosphere. There are advantages such as being able to obtain

By the way, in this type of molding equipment, the container is fixed and the material is handled by inserting and removing the lower lid, so if you want to insert and remove the material at the appropriate position, the main body must be placed far above. Not only is it difficult to operate, but also difficult to monitor, and in the case of a lower heater, it is difficult to wire the lower cover.

The present invention was devised in view of the above-mentioned circumstances, and by fixing the lower lid to a panel etc., the container can be moved up and down, making it easier to put in and take out materials. Therefore, in the present invention, a container having an opening at least on the material loading/unloading side is equipped with a heat insulating material, a heater, etc. inside the container, and the container can be freely inserted into and removed from the inner central space of the frame via the upper and lower surfaces. In the arranged hot isostatic pressing apparatus, a lower lid that closes the opening is attached to the fixed side, and the container removed from the inner central space of the frame can be freely inserted into and removed from the fixed lower lid in the vertical direction. A driving device is provided, and the driving device has a stroke that forms a gap between the upper surface on the fixed lower lid side and the lower surface on the container side, allowing material to enter and exit from the side. Features.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3 showing an example of application to a relatively small hot isostatic pressing apparatus, reference numeral 1 denotes a frame, which is a rectangular frame with a rectangular space 1A inside, and one vertical frame of which is attached to the base plate 2. It is pivotably mounted around a vertical axis via upper and lower hinge devices 3. An upper pressure plate 4 and a lower pressure plate 5 are disposed opposite to each other in the upper and lower central portions of the frame frame 1 .

A container 6 has a heat insulating material 7 built therein, and seal blocks 8 and 9 are inserted into the top and bottom of the container.

Annular upper and lower screw caps 10 and 11 are screwed onto the upper and lower open ends of the container 6 via the seal blocks 8 and 9, thereby forming a container device 12.

The container device 12 has a lower lid 1 with a heater 13
The heater 13 and the lower lid 14 can be freely inserted into and removed from the lower screw lid 11.

That is, the lower lid 14 is attached to the fixed side of the base plate 2 etc. via a support bracket 14A, and the container 6 is provided so as to be vertically insertable and removable with respect to the lower lid 14. In this embodiment, as shown in FIG. , a cylinder tube 15 is installed on one side of the container 6 as shown in FIG.
is fixed, and the upper end of the piston rod 16 fitted into the tube 15 is fixed to the base plate 2 to constitute a telescopic cylinder device 17. As the cylinder device 17 expands, the container 6 moves downward and the heater 1
3. Insert the lower lid 14 into the container 6, and reduce the cylinder device 17 to remove the heater 13 and the lower lid 1.
4, the container 6 is pulled out.

The telescopic cylinder device 17 constitutes a drive device that allows the container 6 removed from the internal central space 1A of the frame 1 to be inserted into and removed from the fixed lower lid 14 in the vertical direction. Now, the telescopic cylinder device 17 performs a stroke to form a gap 18 between the upper surface of the heater 13 mounted on the lower lid 14 and the lower surface on the side of the container 6, which allows materials (including products) to enter and exit from the side. have.

Additionally, in the figure, reference numeral 19 denotes heater wiring, which is buried in the lower lid 14. A protective cover 20 surrounds the entire frame 1, is pivotally connected to the base plate 2 via a hinge device 21, and can be opened and closed.

Reference numeral 22 denotes an instrument panel, in which a plurality of compressors 23 and automatic valves 24 are provided, and a plurality of push buttons 25 on the top surface of the panel.
A plurality of pressure gauges 26 and a plurality of indicator lamps 27
In addition, display instruments such as a plurality of manual valves 28, operating devices, etc. are provided. In the example shown above, both the upper and lower surfaces of the container 6 are open and the openings are closed with the screw caps 10 and 11, but the upper surface of the container 6 may be formed integrally with the main body. Any device may be used as long as it has an opening on the material loading/unloading side and the fixed lid 14 closes this opening.

In the embodiment described above, the material A is charged into the container 6 from below the high-pressure container, that is, the container device 12 of the semi-axial force bearing type. Then, by retracting the drive device 17 represented by a telescopic cylinder device, the container 6 is pulled out from the lower lid 14, and a gap 18 is formed between the lower surface on the container 6 side and the upper surface on the lower lid 14 side. , heater 13 on the lower lid 14
Material A is charged from the side and placed on the heater 13.

Thereafter, the material A is inserted into the container 6 through the lower screw lid 11 etc. by the extension operation of the telescopic cylinder device 17, and the upper surface of the container 6 and the pressure plate 4 of the frame frame 1 are positioned on the same plane, or the upper surface of the container 6 is made pressure resistant. Board 4
Position it slightly lower, in short, frame frame 1
The hinge device 3 is used as a fulcrum to allow the robot to pivot.

Thus, the frame frame 1 is placed in the first position with respect to the container 6.
It is placed in a closed state as shown in Fig. 2,
A container device 12 is placed in the center of the internal rectangular space 1A.
is set, and the heater 13 is energized while the entire body is surrounded by the protective cover 20, and a high-pressure gas is sent into the container 6 through a vent (not shown) to raise the temperature and pressure in the container to sinter the material A. It will be done.

After a predetermined period of time has elapsed and sintering is completed, the inside of the furnace is returned to room temperature and atmospheric pressure, and the protective cover 20 and frame frame 1 are released to open the internal central space 1A.
Then, the container 6 is removed. When the telescopic cylinder device 17 is retracted at this detached position, the container 6 is raised by an amount corresponding to the stroke, and the heater 1
Product A′ on 3 is taken out from container 6, and
A gap 18 is formed between the lower surface on the container 6 side and the upper surface on the lower lid 14 side.

After that, since a gap 18 is formed between the lower surface of the container 6 side and the upper surface of the heater 13, the product
A' is taken out laterally through the gap 18.

The present invention is as described above, and the container device 12 is vertically movable with respect to the fixed lower lid 14, and the material (product) is placed between the upper surface on the fixed lower lid 14 side and the lower surface on the container device 12 side. Since it is possible to form a gap 18 for loading and unloading from the side, materials (products) can be loaded and unloaded at appropriate positions, and there is an advantage that the main body does not have to be placed very high.
The position of the container during processing becomes appropriate, making it very easy to monitor, and it is particularly advantageous to use a lower heater and lower lid wiring, which is of great practical benefit.
