産業上の利用分野
本発明は、２個の発泡金属部材の接合方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for joining two foamed metal members.
従来の技術
発泡金属部材は、内部に無数の気泡を分散させたもので
あり、比重が小さく １．０ｇ／−以下で（たとえば
発泡アルミニウム板で比重０．２〜０．３） 、軽量か

板で熱伝導率０．４５にＣａΩ／ｌ。Conventional technology Foamed metal members have countless air bubbles dispersed inside them, have a small specific gravity of 1.0 g/- or less (for example, a foamed aluminum plate has a specific gravity of 0.2 to 0.3), and are lightweight and fireproof. It is nonflammable, heat insulating (Ji foam aluminum plate has a thermal conductivity of 0.45 CaΩ/l).
ｈｒ、”ｃ）、吸音性がすぐれている。この発泡金属部

造されている。hr, "c), has excellent sound absorption properties. This foamed metal member has traditionally been produced by adding a foaming agent to the molten metal in the mold,
It is manufactured by stirring, leaving to foam, and cooling to solidify.
発明が解決しようとする問題点
発泡金属部材は、上記の方法により製造されているが、
現在のところ製造されているのは３００ｆｌＸ ６００
１１＃ＩＸ ３００＋１１ （厚さ）程度の大きさのも

金型を用いて所定の処理を行なうと、発泡体の内部中央
付近に大きな空洞が生じて、各種性能が著しく低く、実
際に使用できない。従って、大きな発泡金属部材が必要
な場合は、上記のごとき大きさの部材同士を接合するほ

用途に用いられない理由の一つである。Problems to be Solved by the Invention Foamed metal members are manufactured by the above method, but
Currently manufactured is 300flX 600
11 # IX 300 + 11 (thickness) If a large mold is used to perform the specified processing to produce even larger items by foaming, a large cavity will be created near the center of the inside of the foam. Therefore, various performances are extremely low and it cannot be used in practice. Therefore, if a large foamed metal member is required, the only option is to join members of the size described above, but welding is impossible because they are made up of countless bubbles, and joining with ordinary adhesives is difficult. There are problems in that the adhesive easily deteriorates over time and is flammable. These points are one of the reasons why foamed metal members are not used in a wide range of applications, even though they have various excellent properties as described above.
本発明は、上記のごとき問題点が全く認められない、発
泡金属部材の新規な接合方法を提供しようとするもので
ある。The present invention aims to provide a novel method for joining foamed metal members, which is completely free from the above-mentioned problems.
問題燕を解決するための手段
本発明の発泡金属部材の接合方法は、接合させる２個の
発泡金属部材の被接合端面同士を突合わせて開先を設け

徴とするものである。Means for Solving the Problem Swallow The method of joining foamed metal members of the present invention includes the steps of: abutting the end surfaces of two foamed metal members to be joined to each other to form a groove; pouring molten metal into the groove; It is characterized by solidification.
作用
上記のごとく、接合しようとする２個の発泡金属部材の
被接合端面同士を突合わせた開先に、金属溶湯を流し込

に接合される。Function As mentioned above, by pouring molten metal into the groove where the end surfaces of two foamed metal members to be joined are butted together, and cooling and solidifying the molten metal, each foamed metal member is bonded. When the end surfaces to be joined contact and melt the molten metal, the molten metal enters into the bubbles present in the end surfaces to be joined, and when the molten metal is cooled and solidified, the gold ff layer and each end surface to be joined are fused. Due to the anchor effect, the two foamed metal members are firmly joined together through the metal layer.

End face 1a of each short side of 600 ma x thickness 10100 rR,
Add a bevel to 2a and butt them together to create a beveling angle of 90.
A groove portion 3 of ° was provided. Placing plates 4 a and 4 b were placed on both sides of the groove 3 and preheated at 250°C, followed by heating at 90°C.
Molten aluminum 5 heated to 0° C. was poured into groove portion 3 to fill it. After the molten aluminum 5 was left to cool and solidify, the backing plates 4 a and 4 b were removed, and it was found that both foamed aluminum plates 1 and 2 were firmly joined via the aluminum layer. On the side surface of the joint, the contact surfaces of the foamed aluminum 1 and 2 with the molten aluminum 5 are melted and fused to the aluminum layer after solidification, and
Molten aluminum is applied to the end surfaces of foamed aluminum plates 1 and 2 (
It was observed that the air bubbles 1b and 2b present at the bonding surface were penetrated and solidified.

Further, in the above embodiment, a caul plate is used on the side surface of the groove, but it is not necessary to use it. Furthermore, it is preferable that the raw material metal of the gold WA used for joining be the same type as the raw material metal of the foamed metal member, or one that can be mixed with the raw material metal of the foamed metal member, from the viewpoint of the strength of the joint portion.
