〔産業上の利用分野〕
本発明は核融合炉用真空容器の様な複雑三次元形状の大
型薄肉板金構造材の成形を精密に行なう薄肉多層板の製
造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a thin multilayer plate for precisely forming a large thin sheet metal structural member having a complex three-dimensional shape, such as a vacuum vessel for a nuclear fusion reactor.
従来材料メーカーが圧延クラツド鋼の製作の際に第４図
に例示するように平板の被加工材１の上下面にサンドウ
ィッチ材２，２′を［４してサンドウィッチ部材を構成
し、該サンドウィッチ材を面取シ開光形成し、その周囲
溶接７により固縛したのち圧延する方法は採用されてい
た。Conventionally, when manufacturing rolled clad steel, a material manufacturer forms a sandwich member by placing sandwich materials 2, 2' on the upper and lower surfaces of a flat workpiece 1, as shown in FIG. A method was adopted in which the material was chamfered and opened, the circumference of the material was secured by welding 7, and then rolled.
又第５図に例示したものは、前記第４図示の周囲を完全
に溶接固縛したサンドウィッチ部材をプレスによシ雄雌
金型で熱間成形プレス加工する従来方法である。The example shown in FIG. 5 is a conventional method in which the sandwich member shown in FIG. 4, whose periphery is completely welded and secured, is pressed and hot-formed using male and female molds.
ところで、前述のように、圧延クラツド材の製作におい
てはサンドウィッチ材を直接溶接によυその周囲を固縛
して圧延しても、圧延ロールではさみ込みながら延ばし
ており、その溶接固縛部がハズレることはなく支障はな
い。By the way, as mentioned above, in the production of rolled clad materials, even if the sandwich material is directly welded and secured around it and rolled, it is rolled while being sandwiched between rolling rolls, and the welded securing portion is There are no mistakes and no problems.
しかしながら複雑三次元形状のサンドウィッチ部材を第

チ部材の表面は延びと圧縮が複雑に作用している。また
、内外のサンドウィッチ部材の延び量が違うので第４図
のようにサンドウィッチ部材周囲を直接溶接して成形し
た場合成形途中でその溶接部がはずれ口を開き、薄板製
品にしわが発生する不具合がある。However, when a sandwich member with a complex three-dimensional shape is molded using a press using male and female molds as shown in Fig. 5, the outer surface of the sandwich member (the surface that contacts the female mold surface) is free during molding, and Because of three-dimensional molding, the surface of the sandwich member is subject to complex elongation and compression. Additionally, since the length of the inner and outer sandwich members is different, if the sandwich member is directly welded around the sandwich member and formed as shown in Figure 4, the welded part may come off during forming, causing wrinkles in the thin plate product. .
本発明は、前記不具合を解決した新たな薄肉多層板の製
造方法を提供しようとするものである。The present invention aims to provide a new method for manufacturing a thin multilayer board that solves the above-mentioned problems.
このため本発明の薄肉多層板の製造方法は、平板素材の
上下両面をサンドウィッチ板材で挾着した多層状のサン
ドウィッチ部材の周囲を薄肉の平鋼で固縛したのち、金
型により曲げ成形したことを特徴としている。For this reason, the method for producing a thin multilayer board of the present invention involves securing the periphery of a multilayer sandwich member in which the upper and lower surfaces of a flat plate material are sandwiched between sandwich plate materials, and then bending the board using a mold. It is characterized by
サンドウィッチ部材を本発明方法のように平鋼で周囲固
縛すると、その平鋼が成形時伸ばされサンドウィッチ部
材が成形特単独で伸ばされかつ、サンドウィッチ部材同
志が離れないので成形時しわの発生なしに薄板三次元成
形が可能となる。When a sandwich member is circumferentially secured with a flat steel as in the method of the present invention, the flat steel is stretched during forming, the sandwich member is stretched by the forming special alone, and the sandwich members do not separate from each other, so no wrinkles occur during forming. Three-dimensional molding of thin sheets becomes possible.

Fig. 1 is a configuration diagram of a sandwich member according to an embodiment of the present invention, and Fig. 2 is an external view of a molded product manufactured by the method of the present invention. , FIG. 3 shows an explanatory diagram of the completed molding state according to the present invention.

次元形状である。In these figures, 1 is a plate material, 2.2' is a sandwich material that clamps the upper and lower surfaces of the plate material 1, and 3 is a flat steel that surrounds these multilayer plates and is secured by welding 7. A sandwich member 4 is formed using these materials, and the sandwich member is subjected to heating and open-form pressing using a 4-ft male mold 5 and a female mold 6. The molded article 8 formed by the method of the present invention has a complex three-dimensional shape, which is part of a donut shape, as shown in FIG.
本発明製造方法に於ては、被加工素材として例えば材料

成形品のドーナツツ状の外径が約９ｍ、断面の水平寸法

板厚が約６瓢と全体の大きさに比べて板厚は極端に薄い
。In the manufacturing method of the present invention, the material to be processed is, for example, Inconel 625, and the donut-shaped molded product of the present invention shown in FIG. Although it is a large product with a length of approximately 1.5 m, the board thickness is approximately 6 gourds, which is extremely thin compared to the overall size.
従ってこのままで型曲げしようとすれば板材にしわが生
じて製品にならない。Therefore, if you try to bend the plate as it is, wrinkles will occur in the plate and the product will not be finished.
このため本発明では、薄肉大型の複雑三次元形状部材を

３で固縛溶接する方法を採用し、これをプレス成形して
薄肉多層板を製作するものである。For this reason, in the present invention, when forming a thin, large, complex three-dimensional shaped member from a flat plate, the flat plate material 1 is sandwiched between plate materials 2.2', which are called sandwich materials, and are sufficiently thick to prevent the occurrence of wrinkles. A composite plate material 4 called a member is constructed, and the periphery of the sandwich member 4 is secured with flat steel 3 so that the sandwich member does not fall apart due to thermal stress, plastic deformation, etc. during heating for hot forming and forming processing. A welding method is used and then press molding is used to produce a thin multilayer board.
本発明方法によればサンドウィッチ部材４の周囲に平鋼
３を溶接しているので成形特周囲の固縛が外れることな
く、板材料１にしわが発生しない。これによシ第２図に

することができた。According to the method of the present invention, since the flat steel 3 is welded around the sandwich member 4, the lashing around the formed special periphery does not come off and wrinkles do not occur in the plate material 1. As a result, the thin-walled, large-sized, complex three-dimensional shaped member shown in FIG. 2 could be molded without wrinkles.
