Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for opening and closing a pressure vessel that accommodates a material to be treated and compression molds it using hydrostatic pressure, as well as for storing and molding the material to be treated.
The present invention relates to a hydrostatic pressurizing device characterized in that it is equipped with a take-out device.

In conventional hydrostatic pressurizing equipment, press frame type hydrostatic pressurizing equipment is generally used for large-scale equipment or when productivity is required. The process of storing the material to be processed in the taken out pressure vessel, the closing process of tightly fitting the top cover to the pressure vessel, the process of storing the sealed pressure vessel within the window frame of the press frame, and the process of storing the material to be processed in the pressure vessel. The processing process involves applying hydrostatic pressure to the material and then removing the hydrostatic pressure, the process of taking out the pressure vessel from the window frame, the opening process of removing the top cover of the pressure vessel, and the process of removing the processed material from the pressure vessel. Another type has a structure in which the top cover is opened and closed within the window frame, but in any case, the top cover is opened and closed within the window frame of the press frame. The process is designed to apply hydrostatic pressure to prevent the top cover from coming off during this process, and the pressure vessel is placed in the window frame and taken out by fixing the press frame side and moving the pressure vessel side. It can be roughly divided into two types: a method in which the pressure vessel side is fixed and a press frame side is moved.

However, in the above-mentioned hydrostatic pressurizing device, in addition to the steps of storing the pressure vessel within the window frame of the press frame, processing, and taking out the pressure vessel, the process of opening the pressure vessel,
Requires preparation steps for closing, storing and removing materials to be processed,
The cycle time is long, which hinders productivity improvement, and it also has the disadvantage of making automation difficult.

The present invention was developed in order to eliminate the above-mentioned drawbacks of conventional hydrostatic pressurizing devices, and provides a lid for sealing a pressure vessel having a holder for a material to be treated, and an upper part of the lid. A lid gripping tool rotatably attached to the lid, a fluid pressure cylinder that rotates the gripping tool by a predetermined angle, and a drive mechanism that moves up and down the lid gripping mechanism provided with the gripping tool and the fluid pressure cylinder. Its purpose is to open and close the pressure vessel and store and take out the material to be processed at the same time, thereby shortening cycle time and enabling automation. The point is that it provides a pressure device.

The present invention has the above-described structure, and includes a lid for sealing a pressure vessel equipped with a holder for a material to be treated, a lid gripping mechanism for removably gripping the lid, and a lid gripping mechanism that grips the lid in a removable manner. The pressure vessel is equipped with a pressure vessel opening/closing and process material storage/retrieval device consisting of a drive mechanism for the lid gripping mechanism that moves the lid and the material to be processed into and out of the pressure vessel at the same time. It is possible to simultaneously store the material to be processed into the pressure vessel and close it with the lid, as well as open the lid and remove the material from the pressure vessel, reducing cycle time by simplifying the preparation process. In addition to being greatly shortened, each of the above operations can be easily automated only by controlling the drive mechanism, and productivity can be significantly improved.
