Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lid restraining device [d] for a pressure vessel 23, and particularly relates to a lid restraining device [d] for a pressure vessel 23 when granular material is fired or sintered in the pressure vessel. The present invention relates to a device for fixing and holding a lid.

BACKGROUND OF THE INVENTION In recent years, containers that can withstand extremely high pressures have been in high demand because ceramics or granular materials are fired and bonded under high pressure. This type of pressure container 1 is
As shown in FIG. 7, the can body 2 is made up of a cylindrical can body 2 and lids 3, 3 which cover both axial ends of the can body 2.
Since both the lid body 3 and the lid body 3 are made of metal such as &A iron with four dimensions required to have strength capable of withstanding high pressure, the external size and weight are large compared to the internal volume. This pressure-resistant container 1 is constructed by opening one lid 3, charging the object to be processed into the can body 2, closing the lid 3, increasing the pressure inside the container with a fluid such as gas, and heating, etc. Necessary processing is performed. Therefore, when such a processing blade is processed, the cover body 3
, 3 must be applied to the can body 2 with a force capable of resisting the high pressure t, and as a means for this purpose, a press frame 4 as shown in FIG. 8 was used.

The press frame 4 is a rectangular frame 4 in which a rectangular hole 5 is cut out and a short side 5a thereof.

Pressure-resistant container 1 is placed so that lids 3 and 3 are in contact with 5a, respectively.
into the hole 5, determine how much the pressure-resistant container 1 will fit into the press frame 2# as shown by the imaginary line, and fix the lids 3, 3 so as not to open against the pressure applied to the lids 3.3. It was something to do. This press frame 4 itself also needs to have a structure that can withstand the enormous pressure that would damage the lids 3, 3, so it has no choice but to be large in shape and burden.

Problems to be Solved by the Invention However, it goes without saying that the press frame 4 must have a structure that allows the lids 3, 3 to be easily opened before and after processing in the pressure container 1. As a means for this purpose, as shown in FIG.
This depends on whether the pressure container 1 is placed vertically on top of the press frame 4, or on the contrary, the press frame 4 is fixed as shown in FIG. 10 and the pressure container 1 is placed on the carriage 7a. However, this method causes an extremely large loss to the entire device, and the iGR
It also has the disadvantage of requiring a large amount of space. Therefore, as shown in FIG. 11, a method was adopted in which the press frame 4 was provided vertically and rotatably via a hinge 8, and the pressure container 1 was fixedly supported on the movement path of the hole 5. Since a certain pressure-resistant container 1 must be fixedly supported with CtS centering, the structure becomes complicated and there are disadvantages such as the hinge 8 being difficult to fix.

Means for Solving the Problems The present invention aims to solve the above problems by fixing and supporting a pressure-resistant container with its axis m vertically or horizontally, and attaching a rotation axis to a vertical or horizontal plane including the axis. A pressure vessel, which has an opening for pivotally supporting a press frame, and is provided with a driving means for tilting the press frame. I purchased a lid retainer.

Effect of the present invention (According to this invention, the press frame is tilted from a vertical position to either left or right by 10,000 yen from a vertical position or from a horizontal position to either 10,000 yen from a vertical position, and the opening of the press frame into which a pressure-resistant container is fitted is tilted so that the pressure-resistant container is The upper lid can be separated from the upper and lower lids, the upper lid can be lifted up or moved laterally, and removed, the workpiece is inserted into the pressure container, the upper lid is closed again, and the press frame is moved from the inclined position to the vertical position via the drive means. If the counter is rotated in the horizontal position or horizontal position, the opening of the press frame will withstand pressure g 5
The upper side of the opening presses down on the upper lid, and the lower side on the opening presses down on the lower lid, forming a reaction force against the high pressure inside the pressure-resistant container.
