Hot isostatic pressing (hereinafter referred to as HIP) is an isostatic compression of the object using an inert gas as a pressure medium, and is used to manufacture dense sintered bodies from ceramics, metal powder, etc., or from cemented carbide. In recent years, practical use has been progressing one after another as an excellent treatment means for crushing and removing residual pores in metal materials or for diffusion bonding metal materials. By placing a heat insulating layer and a heater in the high-pressure chamber defined by the upper and lower lids, or by placing the heat insulating layer, heater, and object to be processed on the lower lid and removing the lower lid, Devices for loading and unloading heat insulating layers, heaters, and objects to be processed into and out of high-pressure chambers are common, and these devices usually have a separate movable press frame that clamps the top and bottom lids of the high-pressure container. When loading and unloading objects to be processed, etc., the press frame is moved each time.

However, in such a device, when loading and unloading the object to be processed, the HIP device is first sealed, and then the press frame is moved, and after the press frame is moved, the bottom cover is opened to take out the object to be processed. Not only does it have to be pressurized and released from the top and bottom each time, but it also involves moving a relatively large press frame, which increases the size of the equipment and requires installation space. Ta. Moreover, there was also waste in the operation of pressurizing and opening the upper and lower lids.

As is clear from the above explanation, the present invention is a system in which the upper surface of a high-pressure container is brought into contact with the upper pressure-resistant surface of a press frame, and a high-pressure chamber is defined by a lower cover that is fitted into an opening at the lower end. Therefore, in addition to pressurizing the top lid of a conventional high-pressure container, it is also possible to use the top lid in common with the upper pressure-resistant surface of the press frame, and by holding the top surface of the high-pressure container together, it is possible to pressurize the top surface of the high-pressure container. In addition to eliminating the need for special pressure by the press frame, it also eliminates the movement of the large press frame that was conventionally required, and a simple structure is installed between the lower cover and the pressure-resistant surface of the lower part of the press frame. It is sufficient to maintain the pressure by simply installing a pressure block of 1,000 yen, and it has the excellent effect of greatly simplifying the pressure holding mechanism using the conventional press frame. Since it is larger than its height, there is no problem in loading and unloading objects to be processed, and it is expected that its practical use will be promoted in the future, and it will be used as a practical HIP device where equipment rationalization is desired.
