特許文献1には、断面矩形の中空部を備えた構造物の製造方法が開示されている。当該構造物の製造方法は、四つの角部材と、角部材同士を繋ぐ四つの板状部材とを突き合わせた後、突合せ部に対して摩擦攪拌接合を行うというものである。
Patent Document 1 discloses a method for manufacturing a structure having a hollow section having a rectangular cross section. The manufacturing method of the structure is such that after four corner members and four plate-like members connecting the corner members are butted, friction stir welding is performed on the butted portion.
従来技術であると、構造物の内側及び外側から摩擦攪拌接合を行うため、製造工程が煩雑になるという問題がある。特に、構造物の内側から摩擦攪拌接合を行う作業は困難となる。また、板厚が大きい場合は、突合せ部に凹部と当該凹部を覆う補助部材とを用意し、板厚方向に二段階で摩擦攪拌接合を行うことが記載されているが、摩擦攪拌接合の工程が増えて煩雑になるという問題がある。また、従来技術では、複数の中空部を備えた中空構造物の製造方法については開示されていない。
The conventional technology has a problem that the manufacturing process becomes complicated because friction stir welding is performed from the inside and outside of the structure. In particular, it is difficult to perform friction stir welding from the inside of the structure. In addition, when the plate thickness is large, it is described that a concave portion and an auxiliary member that covers the concave portion are prepared in the butt portion, and the friction stir welding is performed in two stages in the plate thickness direction. There is a problem that increases and becomes complicated. Moreover, in the prior art, the manufacturing method of the hollow structure provided with the several hollow part is not indicated.
このような観点から、本発明は、1つ又は複数の中空部を備えた中空構造物を容易に製造することができる中空構造物の製造方法を提供することを課題とする。また、本発明は、複数の板状部材を連結する連結部材と板状部材とを容易に接合することができる接合方法を提供することを課題とする。

Moreover, this invention makes it a subject to provide the joining method which can join easily the connection member and plate member which connect a some plate member.
このような課題を解決するために本発明は、断面矩形の複数の中空部を備えた金属製の中空構造物の製造方法であって、前記中空部を構成する複数の板状部材を成形するとともに、前記中空部の角部を構成し少なくとも二つ以上の前記板状部材を連結する複数の連結部材を押出成形によって成形する準備工程と、断面矩形の中空部が形成されるように各前記板状部材と各前記連結部材とを突き合わせて複数の突合せ部を形成する突合せ工程と、ボビンツールを用いて各前記突合せ部を摩擦攪拌接合する摩擦攪拌工程と、を含むことを特徴とする。

It includes a butting process in which a plate-like member and each of the connecting members are butted together to form a plurality of butting parts, and a friction stirring process in which each of the butting parts is friction stir welded using a bobbin tool.
かかる製造方法によれば、ボビンツールを用いることで、突合せ部の高さ方向の全長を一度に摩擦攪拌接合できるため、中空構造物を容易に製造することができる。また、連結部材は、押出形材であるため、押し出し方向に長い中空構造物を容易に製造することができる。さらに、連結部材及び板状部材を適宜組み合わせることで、複数の断面矩形の中空部を備えた中空構造物を容易に製造することができる。
According to this manufacturing method, by using the bobbin tool, the entire length in the height direction of the butt portion can be friction stir welded at a time, so that a hollow structure can be easily manufactured. In addition, since the connecting member is an extruded profile, a hollow structure that is long in the extrusion direction can be easily manufactured. Furthermore, the hollow structure provided with the hollow part of a some cross-sectional rectangle can be easily manufactured by combining a connection member and a plate-shaped member suitably.

Although the first embodiment of the present invention has been described above, design changes can be made as appropriate without departing from the spirit of the present invention. For example, in the present embodiment, the hollow structure 1 including two hollow portions M is formed, but the number of the hollow portions may be one or three or more. In the present embodiment, the connecting member is formed in a T-shaped cross section, but the corner portion may have an L-shaped cross section. The connecting member may have a cross shape (cross shape) in cross section. In this case, for example, the hollow structure can be formed by adding the hollow parts in the vertical direction and the left-right direction of the hollow part M of the hollow structure 1 shown in FIG. That is, by appropriately combining the connecting member and the plate-like member, a hollow structure having a plurality of rectangular hollow portions can be easily manufactured.

Also, as shown in FIG. 8, a backing material S may be used when performing the friction stirring step. Here, the height dimension of the backing material S is the same as the sum of the height dimension of the extending portions 12 b and 15 b and the height dimension of the plate-like member 24. By using the backing material S, the friction stirring process can be performed stably. The backing material may be used by appropriately setting the height dimension in the second to fifth steps. Moreover, the manufacturing method of an above described hollow structure is an example, Comprising: This invention is not limited.

以上説明した第十一実施形態の変形例に係る接合方法のように、連結部材15Aのうち、端部(端面)の板厚が他の部位の端部の板厚よりも小さく(薄く)なっていてもよい。言い換えると、基部15aの両端部及び延設部15bの端部のいずれか一つの板厚が、基部15aの両端部及び延設部15bの端部の他の板厚と異なるように形成してもよい。これにより、設計の自由度を向上させるこができる。例えば、図1に示す中空構造物1における連結部材15及び板状部材27を、連結部材15A及び板状部材27Aに置き換えてもよい。これにより、中空構造物を構成する板状部材のうち、一部の板厚を薄くすることができる。また、第十一実施形態及び第十一実施形態の変形例では、断面放射状又はT字状の連結部材を例示したが、接合方法に係る連結部材は、断面I字状、断面K字状又は断面十字状(クロス状)等少なくとも3つの板状部材を連結可能であればよい。
Like the joining method according to the modified example of the eleventh embodiment described above, the plate thickness of the end portion (end surface) of the connecting member 15A is smaller (thinner) than the plate thickness of the end portion of the other part. It may be. In other words, the thickness of any one of the both end portions of the base portion 15a and the end portion of the extending portion 15b is different from the other plate thicknesses of both end portions of the base portion 15a and the end portion of the extending portion 15b. Also good. Thereby, the freedom degree of design can be improved. For example, the connecting member 15 and the plate-like member 27 in the hollow structure 1 shown in FIG. 1 may be replaced with the connecting member 15A and the plate-like member 27A. Thereby, some board thickness can be made thin among the plate-shaped members which comprise a hollow structure. In addition, in the eleventh embodiment and the modification of the eleventh embodiment, the connecting member having a radial cross section or a T-shape is illustrated, but the connecting member according to the joining method may be an I-shaped cross section, a K-shaped cross section, or It is sufficient that at least three plate-like members such as a cross-shaped cross (cross-shaped) can be connected.
