Description

Isostatic pressure molding device and method {ISOSTATIC PRESS FORMING APPARATUS AND METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an isostatic pressure molding device, and more particularly, to a technique for heating isostatically pressurized materials such as metals, ceramics, resins, and foods and efficiently isostatically pressurizing it.

As an isotropic pressure molding method for isostatically pressurizing an article to be pressurized efficiently, for example, Japanese Patent Application Laid-open No. Hei 5-16960 and Japanese Patent Laid-Open No. 2002-35995 have been proposed.

The hot water isotropic pressure pressurization device proposed in Japanese Patent Application Laid-open No. Hei 5-16960 discloses a pressure vessel immersed in hot water in a tank so that an opening for entering a pressurized object is located above the hot water liquid level. In the hot water isotropic pressure pressurizing device which press-forms this to-be-pressed object by accommodating the to-be-loaded object in the rack attached to the lower surface of the cover which is hermetically sealed, and storing this to-be-pressed object in a reaction container and press-fitting hot water. The lid lifting device for lowering the lid from above the opening to be mounted in the opening by driving a piston engaged with the lid by air pressure, and raising the lid attached to the opening to open the opening. At the same time, the cover is rotated with the piston as the axis to the upper position of the opening and other positions. It is configured so as to install the cover and the rotation device, to prevent the operability decreases due to the vapor of interest by this configuration.

In the technique proposed in Japanese Patent Application Laid-open No. Hei 5-16960, it is possible to prevent deterioration of workability due to steam, but it is necessary to rotate the lid of the pressure vessel after the rise, thereby becoming a large-scale apparatus. In addition, after the lid is raised and rotated, the pressure vessel cannot be operated unless the lid is returned above the vessel and lowered and mounted in the opening, so the efficiency is not very good.

Further, the isotropic pressure molding method proposed in Japanese Unexamined Patent Application Publication No. 2002-35995 has a preheating step of preheating a holding means for holding the pressurized object in a predetermined shape, and after the preheating step, It has a shaping | molding process which accompanies it in the pressure container in the state hold | maintained by the said holding means, injects a high temperature liquid into a pressure vessel, heats it, and performs isotropic pressurization through the said liquid, Next shaping | molding in the said shaping process By heating by the said preheating process with respect to the to-be-pressurized object which carries out the following, a tact time can be shortened by this. In summary, a work (pressurized material) consisting of a plate (holding support means) and a stacked body stacked thereon is carried into the basket at the carry-in / out station. Each basket is transferred to a preheating station where it is heated. Furthermore, it transfers to a press molding station, and injects into a pressure vessel here. Hot water of high temperature is supplied to the pressure vessel, heated and pressurized to form a laminate. After molding, the basket is returned to the carry-in / out station and isotropically press-molded by the process of taking out a workpiece from a basket, etc., and the tact time can be shortened.

In the technique proposed in Japanese Patent Laid-Open No. 2002-35995, the efficiency is higher than the conventional technique proposed in Japanese Patent Application Laid-open No. Hei 5-16960. However, the line which conveys the workpiece | work and basket after preheating to a press molding station, and the line which returns the workpiece | work and basket after press molding to a carry-in / out station are partially overlapped. For this reason, as long as the workpiece | work and basket after press molding cannot pass through the overlapping line, the workpiece | work and basket after preheating cannot be returned to a press molding station, and for the same reason, unless the workpiece | work and basket after preheating pass through the overlap line, Next, a situation arises in which the workpieces and baskets to be preheated cannot be fed to the preheating station, and the tact time is not necessarily shortened sufficiently. In particular, when the workpiece and basket after pre-heating cannot be conveyed to the pressure forming station unless the workpiece and the basket after the former pressure molding pass through the overlapping line, the empty time of the pressure vessel becomes large, and the productivity of the pressurized product is increased. There is room for improvement because it worsens.

Hereinafter, the isotropic pressure pressurization process of the to-be-processed object 4 can be performed efficiently by repeating the operation | work and operation from FIG.10 (a)-FIG.11 (h). In particular, as shown in Figs. 10C to 11E, the preheating processing unit 37 is replaced with taking out the workpiece 4 after isotropic pressure pressurization to the discharge unit 38. Since the to-be-processed object 4 after a preheating process can be carried in to the pressurization station 33 and can be loaded in the pressure vessel 17, the empty time of the pressure vessel 17 can be reduced. In addition, also in this embodiment, as shown to FIG. 10 (d)-FIG. 11 (f), after carrying out the to-be-processed object 4 after the preheating process of the preheating process part 37 to the pressurizing station 33, The next to-be-processed object 4 can be carried in to the preheating process part 37 from the carry-in and take-out station 31 in the position, and it operates rather than the type which raises and lowers a rack in the above-mentioned preheating station 2. This is a bit simpler.

In addition, although the charge handling apparatus mentioned above has a total of two each, one each a preprocessing part and a carrying out part, you may have two or more preliminary processing parts or a carrying part in total.

The present invention relates to a bin of a pressure vessel which has a great influence on the productivity of a workpiece (including a pressurized object that can be treated with a single member, or a pressurized object stored in a receiving jig such as a basket). It is effective to provide an isostatic pressure molding apparatus and method which can reduce the time as much as possible.
