No. 2006-341300

上述したような外板パネル及び骨部材といった金属材の接合では、接合強度を確保する観点から、接合を行う際の各金属材の密着性が重要となっている。しかしながら、金属材には、プレス加工やロールフォーミング加工といった成形工程で製造ばらつきが生じることが多い。製造ばらつきが大きく所望の形状が得られていない場合、外板パネルに骨部材を載置した際に金属材のフランジ部が外板パネルに対して浮いてしまい、密着性が損なわれることが有り得る。   In the joining of metal materials such as the outer panel and the bone member as described above, the adhesion of each metal material at the time of joining is important from the viewpoint of securing the joining strength. However, manufacturing variations often occur in metal materials in a molding process such as press working or roll forming. When manufacturing variation is large and a desired shape is not obtained, when a bone member is placed on the outer panel, the flange portion of the metal material may float with respect to the outer panel, and adhesion may be impaired. .

一般的な方法としては、溶接ヘッドに取り付けた加圧ローラなどで骨部材のフランジ部を外板パネルに押し付ける方法などが採用されている。しかしながら、金属材の屈曲部分は加工硬化していることが多いため、外板パネルに密着させるようにフランジ部を加圧すると、屈曲部分の形状が保存されたままフランジ部が変形してしまう場合があった。そのため、フランジ部の平坦性が損なわれ、接合の際における各金属材の密着性の確保が困難となる場合があった。   As a general method, a method of pressing a flange portion of a bone member against an outer panel with a pressure roller attached to a welding head or the like is employed. However, since the bent part of the metal material is often work-hardened, if the flange part is pressed so as to be in close contact with the outer panel, the flange part may be deformed while the shape of the bent part is preserved. was there. For this reason, the flatness of the flange portion is impaired, and it may be difficult to ensure the adhesion of each metal material during bonding.

本発明は、上記課題の解決のためになされたものであり、接合の際における各金属材の密着性を十分に確保できる金属材の接合方法及びこれに用いる金属材を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a metal material joining method capable of sufficiently ensuring the adhesion of each metal material during joining, and a metal material used in the method. To do.

上記課題の解決のため、本発明に係る金属材の接合方法は、面板状の第１の金属材に対し、面板状の頂部、頂部の両端部に立設されたウェブ部、ウェブ部の先端部から外側に突出するように設けられたフランジ部を備えた長尺の第２の金属材を接合する金属材の接合方法であって、第２の金属材のフランジ部は、その先端部が基端部に対して頂部側に位置するように傾斜しており、第２の金属材におけるウェブ部を内側に向かって加圧しながら、第１の金属材に当接させたフランジ部の長手方向に沿って溶接部を形成することを特徴としている。   In order to solve the above-mentioned problems, the metal material joining method according to the present invention is a face plate-like first metal material, a face plate-like top portion, a web portion erected at both ends of the top portion, and a tip of the web portion. A metal material joining method for joining a long second metal material provided with a flange portion provided so as to protrude outward from the portion, wherein the flange portion of the second metal material has a tip portion thereof. The longitudinal direction of the flange portion which is inclined so as to be located on the top side with respect to the base end portion and presses the web portion of the second metal material inward while being brought into contact with the first metal material It is characterized in that a welded portion is formed along.

この金属材の接合方法では、面板状の第１の金属材に接合する第２の金属材として、フランジの先端部が基端部に対して頂部側に位置するように傾斜したものを用いる。そして、第２の金属材のフランジ部を第１の金属材に当接させるに際し、第２の金属材のウェブ部を内側に向かって加圧する。これにより、ウェブ部の先端部から外側に突出するフランジ部が、加圧によって内側に傾動するウェブ部の角度に応じて第１の金属材側に傾動し、フランジ部全体が第１の金属材に密着することとなる。この金属材の接合方法では、第２の金属材におけるウェブ部を変形させるが、ウェブ部とフランジ部との交差部分は変形させない。そのため、フランジ部の傾動にあたって、当該交差部分の形状が保存されたままフランジ部が変形してしまうことはなく、フランジ部と第１の金属材との密着性を十分に確保することができる。   In this metal material joining method, the second metal material to be joined to the face plate-like first metal material is one that is inclined so that the distal end portion of the flange is positioned on the top side with respect to the proximal end portion. Then, when the flange portion of the second metal material is brought into contact with the first metal material, the web portion of the second metal material is pressurized inward. Thereby, the flange part which protrudes outside from the front-end | tip part of a web part inclines to the 1st metal material side according to the angle of the web part which inclines inside by pressurization, and the whole flange part is the 1st metal material. Will be in close contact. In this metal material joining method, the web portion of the second metal material is deformed, but the intersecting portion of the web portion and the flange portion is not deformed. Therefore, when the flange portion is tilted, the flange portion is not deformed while the shape of the intersecting portion is preserved, and sufficient adhesion between the flange portion and the first metal material can be ensured.

また、ウェブ部を第２の金属材の長手方向に沿ってそれぞれ加圧することが好ましい。こうすると、より確実にフランジ部の第１の金属材への傾動を行うことができる。また、加圧によるウェブ部の変形も防止できる。   Moreover, it is preferable to pressurize a web part along the longitudinal direction of a 2nd metal material, respectively. If it carries out like this, tilting to the 1st metal material of a flange part can be performed more reliably. Further, deformation of the web portion due to pressurization can be prevented.

また、溶接部をレーザ溶接によって形成することが好ましい。これにより、接合部分の機械的強度を十分に確保できる。   Moreover, it is preferable to form a welding part by laser welding. Thereby, the mechanical strength of the joint portion can be sufficiently secured.

また、本発明に係る金属材は、面板状の頂部、頂部の両端部に立設されたウェブ部、ウェブ部の端部から外側に突出するように設けられたフランジ部を備え、フランジ部は、その先端部が基端部に対して頂部側に位置するように傾斜していることを特徴としている。   Further, the metal material according to the present invention includes a face plate-like top portion, a web portion erected on both ends of the top portion, and a flange portion provided so as to protrude outward from the end portion of the web portion, The tip portion is inclined so as to be located on the top side with respect to the base end portion.

この金属材では、ウェブ部を内側に向かって加圧することにより、ウェブ部の先端部から外側に突出するフランジ部を傾動させることができ、フランジ部全体を面板状の金属材に密着させることが可能となっている。ウェブ部を加圧し、ウェブ部とフランジ部との交差部分には加圧力を加えないことで、フランジ部の傾動にあたって当該交差部分の形状が保存されたままフランジ部が変形してしまうことはなく、フランジ部と第１の金属材との密着性を十分に確保することができる。   In this metal material, by pressing the web portion inward, the flange portion protruding outward from the tip portion of the web portion can be tilted, and the entire flange portion can be brought into close contact with the face plate-like metal material. It is possible. By pressing the web part and applying no pressure to the intersection between the web part and the flange part, the flange part will not be deformed while the shape of the intersection part is preserved when the flange part is tilted. Adequate adhesion between the flange portion and the first metal material can be ensured.

本発明に係る金属材の接合方法及び金属材によれば、接合の際における各金属材の密着性を十分に確保できる金属材の接合方法及びこれに用いる金属材を提供する。   According to the metal material joining method and the metal material according to the present invention, there are provided a metal material joining method capable of sufficiently ensuring the adhesion of each metal material at the time of joining, and a metal material used therefor.

以下、図面を参照しながら、本発明に係る金属材の接合方法及び金属材の好適な実施形態について詳細に説明する。   Hereinafter, preferred embodiments of a metal material joining method and a metal material according to the present invention will be described in detail with reference to the drawings.

図１は、本発明の一実施形態に係る金属材の接合方法を用いて接合した金属材の一例を示す斜視図である。図１に示す例では、鉄道車両（図示せず）の側構体を構成する外板パネル（第１の金属材）１と、外板パネル１を補強する骨部材（第２の金属材）２とを接合している。   FIG. 1 is a perspective view showing an example of a metal material joined by using a metal material joining method according to an embodiment of the present invention. In the example shown in FIG. 1, an outer panel (first metal material) 1 constituting a side structure of a railway vehicle (not shown) and a bone member (second metal material) 2 that reinforces the outer panel 1. And are joined.

外板パネル１は、例えばステンレス鋼からなり、厚さ約２ｍｍの面板状をなしている。外板パネル１は、鉄道車両の窓よりも上方の部分を構成する幕パネル、窓よりも下方の部分を構成する腰パネル、窓とドアとの間の部分を構成する吹寄せパネルといった側構体の各部分を構成する。なお、外板パネル１の材質は、アルミ合金、高張力鋼、その他の一般鋼であってもよい。   The outer panel 1 is made of, for example, stainless steel and has a face plate shape with a thickness of about 2 mm. The outer panel 1 is composed of a side panel such as a curtain panel that forms a portion above the window of the railway vehicle, a waist panel that forms a portion below the window, and a blowing panel that forms a portion between the window and the door. Configure each part. The material of the outer panel 1 may be an aluminum alloy, high-tensile steel, or other general steel.

骨部材２は、例えばステンレス鋼からなる長尺の型材であり、厚さ約２ｍｍの断面ハット状をなしている。骨部材２は、面板状の頂部２１と、頂部２１の両端部２１ａにそれぞれ立設される一対のウェブ部２２，２２によって構成されるチャンネル部２０と、各ウェブ部２２，２２の先端部２２ａから外側に突出する一対のフランジ部２３，２３とを備えている。   The bone member 2 is a long mold made of stainless steel, for example, and has a cross-sectional hat shape with a thickness of about 2 mm. The bone member 2 includes a face plate-like top portion 21, a channel portion 20 constituted by a pair of web portions 22, 22 erected on both end portions 21 a of the top portion 21, and tip portions 22 a of the web portions 22, 22. And a pair of flange portions 23 and 23 projecting outward.

骨部材２は、チャンネル部２０が鉄道車両の車室内側に突出するようにして、鉄道車両の長手方向（水平方向）に沿って延在している。骨部材２のフランジ部２３，２３は、外板パネル１の内面側に密着した状態となっている。そして、骨部材２は、フランジ部２３，２３の長手方向に沿って所定の間隔で形成されたスポット状の溶接部Ｗにより、外板パネル１の内面１ａに強固に固定されている。   The bone member 2 extends along the longitudinal direction (horizontal direction) of the railway vehicle such that the channel portion 20 protrudes toward the passenger compartment side of the railway vehicle. The flange portions 23 and 23 of the bone member 2 are in close contact with the inner surface side of the outer panel 1. The bone member 2 is firmly fixed to the inner surface 1 a of the outer panel 1 by spot-like welded portions W formed at predetermined intervals along the longitudinal direction of the flange portions 23, 23.

続いて、上述した外板パネル１と骨部材２との接合方法について説明する。   Next, a method for joining the outer panel 1 and the bone member 2 described above will be described.

まず、図２に示すように、外板パネル１と骨部材２とを用意する。骨部材２としては、例えば頂部２１の幅が約５０ｍｍ、ウェブ部２２の高さが約４０ｍｍ、フランジ部２３，２３の幅が約３０ｍｍのものを用いる。また、骨部材２においては、頂部２１とウェブ部２２とがなす開放角θ１が約９０°となっているのに対し、ウェブ部２２とフランジ部２３とがなす開放角θ２が約８８°となっている。   First, as shown in FIG. 2, an outer panel 1 and a bone member 2 are prepared. As the bone member 2, for example, a material having a width of the top portion 21 of about 50 mm, a height of the web portion 22 of about 40 mm, and a width of the flange portions 23 and 23 of about 30 mm is used. Further, in the bone member 2, the opening angle θ1 formed by the top portion 21 and the web portion 22 is about 90 °, whereas the opening angle θ2 formed by the web portion 22 and the flange portion 23 is about 88 °. It has become.

このように、接合前の骨部材２のフランジ部２３，２３は、各ウェブ部２２，２２の先端部２２ａからウェブ部２２，２２に対して直角に突出するのではなく、フランジ部２３，２３の先端部２３ａが基端部２３ｂに対して頂部２１側に位置するように、頂部２１側に約２°程度傾斜して突出した状態となっている。   Thus, the flange parts 23 and 23 of the bone member 2 before joining do not protrude at right angles to the web parts 22 and 22 from the tip parts 22a of the web parts 22 and 22, but the flange parts 23 and 23. It is in the state which protruded inclining about 2 degrees to the top part 21 side so that the front-end | tip part 23a may be located in the top part 21 side with respect to the base end part 23b.

外板パネル１と骨部材２とを用意した後、まず、内面１ａを上向きにして外板パネル１を定盤（図示せず）上に載置する。次に、チャンネル部２０が外板パネル１の内面１ａから突出するような向きにして、骨部材２を外板パネル１上に載置する。このとき、上述したように、骨部材２のフランジ部２３，２３が頂部２１側に約２°程度傾斜して突出した状態となっているため、骨部材２を外板パネル１上に載置すると、骨部材２は、フランジ部２３，２３の基端部２３ｂのみが外板パネル１の内面１ａに当接することとなる。   After preparing the outer panel 1 and the bone member 2, first, the outer panel 1 is placed on a surface plate (not shown) with the inner surface 1a facing upward. Next, the bone member 2 is placed on the outer panel 1 in such a direction that the channel portion 20 protrudes from the inner surface 1 a of the outer panel 1. At this time, as described above, since the flange portions 23 and 23 of the bone member 2 are inclined and projecting about 2 ° toward the top portion 21 side, the bone member 2 is placed on the outer panel 1. Then, in the bone member 2, only the base end portion 23 b of the flange portions 23, 23 comes into contact with the inner surface 1 a of the outer panel 1.

次に、加圧装置（図示せず）を用いて骨部材２への加圧を行う。加圧装置は、長尺の押さえ板３１を有する加圧治具３２を複数（本実施形態では２つ）備えている。固定装置は、動作開始を指示する動作指示情報の入力を受けると、骨部材２のウェブ部２２の外方からチャンネル部２０を挟み込むように加圧治具３２，３２をそれぞれスライドさせる。そして、ウェブ部２２の略中央部分に押さえ板３１を押し当てることにより、骨部材２の長手方向に沿って、ウェブ部２２をチャンネル部２０の内側に向けてそれぞれ加圧する。   Next, the bone member 2 is pressurized using a pressure device (not shown). The pressure device includes a plurality (two in the present embodiment) of pressure jigs 32 each having a long pressing plate 31. When receiving the operation instruction information for instructing the operation start, the fixing device slides the pressing jigs 32 and 32 so as to sandwich the channel portion 20 from the outside of the web portion 22 of the bone member 2. Then, the web plate 22 is pressed toward the inside of the channel unit 20 along the longitudinal direction of the bone member 2 by pressing the pressing plate 31 against the substantially central portion of the web unit 22.

加圧治具３２，３２によるウェブ部２２への加圧により、ウェブ部２２は、頂部２１の両端部２１ａが支点となって、ウェブ部２２の先端部２２ａ同士が互いに接近するように、チャンネル部２０の内側に向かって約２°程度傾動する。これにより、ウェブ部２２の先端部２２ａから屈曲して外側に突出するフランジ部２３が、加圧によって内側に傾動したウェブ部２２の角度に応じて外板パネル１側に約２°程度傾動する。したがって、フランジ部２３は、外板パネル１ａと略平行な状態となり、フランジ部２３全体が外板パネル１の内面１ａに密着することとなる。   By pressing the web part 22 with the pressurizing jigs 32, 32, the web part 22 is channeled so that both end parts 21 a of the top part 21 serve as fulcrums and the front end parts 22 a of the web part 22 approach each other. It tilts about 2 ° toward the inside of the portion 20. As a result, the flange portion 23 that is bent from the front end portion 22a of the web portion 22 and protrudes outwardly is tilted by about 2 ° toward the outer panel 1 in accordance with the angle of the web portion 22 that is tilted inward by pressurization. . Therefore, the flange part 23 will be in a substantially parallel state with the outer panel 1a, and the entire flange part 23 will be in close contact with the inner surface 1a of the outer panel 1.

最後に、加圧治具３２，３２による骨部材２への加圧を続けながら、レーザ溶接ヘッド３３をフランジ部２３の上方にセットする。そして、レーザ溶接ヘッド３３をフランジ部２３の長手方向に沿って相対移動させながら、レーザ溶接ヘッド３３の先端から例えば波長１．０６μｍ、出力約４．０ｋＷのＹＡＧレーザを所定の時間間隔で出射させる。これにより、フランジ部２３の略中央部分に、フランジ部２３の長手方向に沿って所定の間隔でスポット状の溶接部Ｗが形成され、図１に示した外板パネル１と骨部材２との接合材が完成する。   Finally, the laser welding head 33 is set above the flange portion 23 while continuing to press the bone member 2 with the pressing jigs 32 and 32. Then, for example, a YAG laser having a wavelength of 1.06 μm and an output of about 4.0 kW is emitted at a predetermined time interval from the tip of the laser welding head 33 while the laser welding head 33 is relatively moved along the longitudinal direction of the flange portion 23. . Thereby, spot-like welded portions W are formed at predetermined intervals along the longitudinal direction of the flange portion 23 at a substantially central portion of the flange portion 23, and the outer panel 1 and the bone member 2 shown in FIG. The joining material is completed.

以上説明したように、本実施形態に係る金属材の接合方法では、外板パネル１に接合する骨部材２として、フランジ２３の先端部２３ａが基端部２３ｂに対して頂部２１側に位置するように傾斜したものを用いる。そして、骨部材２のフランジ部２３を外板パネル１に当接させるに際し、骨部材２におけるウェブ部２２を内側に向かって加圧し、ウェブ部２２の先端部２２ａから外側に突出するフランジ部２３を外板パネル１側に傾動させる。   As described above, in the metal material joining method according to the present embodiment, the distal end portion 23a of the flange 23 is positioned on the top portion 21 side with respect to the base end portion 23b as the bone member 2 to be joined to the outer panel 1. A slanted product is used. When the flange portion 23 of the bone member 2 is brought into contact with the outer panel 1, the web portion 22 in the bone member 2 is pressurized inward and the flange portion 23 protrudes outward from the tip portion 22 a of the web portion 22. Is tilted toward the outer panel 1 side.

フランジ部２３を外板パネル２３に向けて上方から直接加圧する場合、フランジ部２３が変形する際に、屈曲によって加工硬化しているウェブ部２２とフランジ部２３との交差部分の形状が保存されてしまうことがある。この場合、フランジ部２３の平坦性が損なわれ、外板パネル１との密着性の確保が困難となる。これに対し、本実施形態に係る金属材の接合方法では、骨部材２におけるウェブ部２２を変形させており、ウェブ部２２とフランジ部２３との交差部分を変形させてはいない。したがって、当該交差部分の形状が保存されたままフランジ部２３が変形してしまうことはなく、フランジ部２３と外板パネル１との十分な密着性が確保される。この結果、接合材の接合強度が十分に確保される。   When the flange portion 23 is directly pressed from above toward the outer panel 23, the shape of the intersecting portion between the web portion 22 and the flange portion 23 that is work-hardened by bending is preserved when the flange portion 23 is deformed. May end up. In this case, the flatness of the flange portion 23 is impaired, and it becomes difficult to ensure adhesion with the outer panel 1. On the other hand, in the joining method of the metal material which concerns on this embodiment, the web part 22 in the bone member 2 is deformed, and the intersection part of the web part 22 and the flange part 23 is not deformed. Therefore, the flange portion 23 is not deformed while the shape of the intersecting portion is preserved, and sufficient adhesion between the flange portion 23 and the outer panel 1 is ensured. As a result, the bonding strength of the bonding material is sufficiently ensured.

また、フランジ部２３の傾動においては、頂部２１とウェブ部２２とがなす開放角θ１が小さくなる方向にウェブ部２２を加圧し、ウェブ部２２及びフランジ部２３を、頂部２１の両端部２１ａを固定端とする単純支持梁のように変形させている。このような変形の実現にあたっては、フランジ部２３を外板パネル２３に向けて上方から直接加圧する場合のように、ウェブ部２２とフランジ部２３とがなす開放角θ２が大きくなる方向にフランジ部２３を加圧する場合と比べると、小さい加圧力で済む。したがって、加圧装置の大型化を抑制できる。   Further, in the tilting of the flange portion 23, the web portion 22 is pressurized in a direction in which the opening angle θ1 formed by the top portion 21 and the web portion 22 is reduced, and the web portion 22 and the flange portion 23 are connected to both end portions 21a of the top portion 21. It is deformed like a simple support beam with a fixed end. In realizing such a deformation, the flange portion is formed in the direction in which the opening angle θ2 formed by the web portion 22 and the flange portion 23 is increased, as in the case of directly pressing the flange portion 23 toward the outer panel 23 from above. Compared with the case of pressurizing 23, a small pressing force is sufficient. Therefore, the enlargement of the pressurizing device can be suppressed.

さらに、この金属材の接合方法では、加圧治具３２，３２により、ウェブ部２２の略中央部分を骨部材２の長手方向に沿ってそれぞれ加圧している。このような構成により、より確実にウェブ部２２の傾動を行うことができ、フランジ部２３と外板パネル１との密着性が更に高められる。また、加圧によってウェブ部２２が変形してしまうことも抑制される。   Furthermore, in this metal material joining method, the pressing jigs 32, 32 press the substantially central portion of the web portion 22 along the longitudinal direction of the bone member 2. With such a configuration, the web portion 22 can be tilted more reliably, and the adhesion between the flange portion 23 and the outer panel 1 is further enhanced. Moreover, it is suppressed that the web part 22 deform | transforms by pressurization.

本発明は、上記実施形態に限られるものではない。例えば骨部材２は、フランジ部２３の先端部２３ａが基端部２３ｂに対して頂部２１側に位置するように傾斜しているものであればよく、頂部２１とウェブ部２２とは必ずしも直交していなくてもよい。例えば図４（ａ）に示すように、頂部２１とウェブ部２２とがなす開放角θ１が約９２°となっている骨部材４１を用いてもよいし、例えば図４（ｂ）に示すように、頂部２１とウェブ部２２とがなす開放角θ１が約８８°となっている骨部材４２を用いてもよい。   The present invention is not limited to the above embodiment. For example, the bone member 2 only needs to be inclined so that the distal end portion 23a of the flange portion 23 is positioned on the top portion 21 side with respect to the proximal end portion 23b, and the top portion 21 and the web portion 22 are not necessarily orthogonal to each other. It does not have to be. For example, as shown in FIG. 4A, a bone member 41 having an opening angle θ1 formed by the top portion 21 and the web portion 22 of about 92 ° may be used. For example, as shown in FIG. Alternatively, a bone member 42 having an opening angle θ1 formed by the top portion 21 and the web portion 22 of about 88 ° may be used.

骨部材４１，４２のいずれにおいても、ウェブ部２２とフランジ部２３とがなす開放角θ２は、上述した骨部材２と同様に約８８°となっている。このような骨部材４１，４２を用いても、接合の際にウェブ部２２を内側に加圧することにより、外板パネル１とフランジ部２３との密着性を容易に確保することが可能である。また、溶接部Ｗは、スポット状に限られることはなく、フランジ部２３の長手方向に沿った連続溶接部であってもよい。   In any of the bone members 41 and 42, the opening angle θ2 formed by the web portion 22 and the flange portion 23 is about 88 ° as in the bone member 2 described above. Even when such bone members 41 and 42 are used, it is possible to easily ensure the adhesion between the outer panel 1 and the flange portion 23 by pressing the web portion 22 inward during the joining. . Further, the welded portion W is not limited to a spot shape, and may be a continuous welded portion along the longitudinal direction of the flange portion 23.
