Including.

突合工程では、図１の（ａ）および（ｂ）に示すように、金属要素１０，２０を突き合せるとともに、その突合部Ｊの両側に第一タブ部１１と第二タブ部１２を位置させる。具体的には、一の金属要素１０と第一タブ部１１と第二タブ部１２とで形成される凹部に他の金属要素２０を嵌め込み、第一タブ部１１の側面１１ｂおよび第二タブ部１２の側面１２ｂをそれぞれ他の金属要素２０の側面２０ｂに当接させつつ、一の金属要素１０の端面（突合面）１０ａと他の金属要素２０の端面（突合面）２０ａとを当接させればよい。   In the abutting step, as shown in FIGS. 1A and 1B, the metal elements 10 and 20 are abutted, and the first tab portion 11 and the second tab portion 12 are positioned on both sides of the abutting portion J. . Specifically, the other metal element 20 is fitted into the recess formed by the one metal element 10, the first tab part 11, and the second tab part 12, and the side surface 11 b and the second tab part of the first tab part 11 are inserted. While the 12 side surfaces 12b are brought into contact with the side surfaces 20b of the other metal elements 20, the end surface (butting surface) 10a of one metal element 10 and the end surface (butting surface) 20a of the other metal element 20 are brought into contact with each other. Just do it.

拘束工程では、図１の（ｂ）に示すように、第一部材Ａ１および第二部材Ａ２を図示せぬ架台に移動不能に拘束することで、金属要素１０，２０を拘束する。本実施形態では、第一タブ部１１および第二タブ部１２の側面にブロック３０を宛がうとともに、金属要素１０，２０、第一タブ部１１および第二タブ部１２の上面の押え部Ｐ，Ｐ，…を図示せぬクランプ等で押さえ込むことで、第一部材Ａ１および第二部材Ａ２を拘束する。なお、押え部Ｐの位置や個数は、金属要素１０，２０の形状や大きさ等に応じて適宜変更しても差し支えない。   In the restraining step, the metal elements 10 and 20 are restrained by restraining the first member A1 and the second member A2 so as not to move to a gantry (not shown) as shown in FIG. In the present embodiment, the block 30 is applied to the side surfaces of the first tab portion 11 and the second tab portion 12, and the pressing portion P on the upper surface of the metal elements 10, 20, the first tab portion 11 and the second tab portion 12. , P,... Are restrained by a clamp (not shown) to restrain the first member A1 and the second member A2. It should be noted that the position and number of the presser portions P may be appropriately changed according to the shape and size of the metal elements 10 and 20.

熱加工工程では、図１の（ｃ）に示すように、突合部Ｊに対して連続して摩擦攪拌を行う。具体的には、回転させた回転ツール４０の攪拌ピン４２（図２参照）を第一タブ部１１に設けた開始位置Ｓに挿入（圧入）するとともに、挿入した攪拌ピン４２を途中で離脱させることなく金属要素１０，２０の継ぎ目（境界線）を含むように設定した摩擦攪拌のルートに沿って相対移動させることで突合部Ｊに対して連続して摩擦攪拌を行い、さらに、第二タブ部１２に設けた終了位置Ｅまで連続して摩擦攪拌を行ったうえで、終了位置Ｅで攪拌ピン４２を上方に離脱させればよい。回転ツール４０を回転させつつ突合部Ｊに沿って移動させると、回転ツール４０と金属との摩擦熱により突合部Ｊの金属が塑性流動化し、突合部Ｊが固相接合される。なお、摩擦攪拌の開始位置Ｓおよび終了位置Ｅは、それぞれ第一タブ部１１および第二タブ部１２の適所に設けることができるが、本実施形態では、金属要素１０，２０の継ぎ目の延長線上に開始位置Ｓおよび終了位置Ｅを設けている。このようにすると、摩擦攪拌のルートが一直線になり、回転ツール４０の移動距離を最小限に抑えることができるので、熱加工工程を効率よく行うことが可能となり、さらには、回転ツール４０の磨耗量を低減することが可能となる。   In the thermal processing step, friction agitation is continuously performed on the abutting portion J as shown in FIG. Specifically, the stirring pin 42 (see FIG. 2) of the rotated rotating tool 40 is inserted (press-fitted) into the start position S provided on the first tab portion 11, and the inserted stirring pin 42 is removed halfway. The frictional stirring is continuously performed with respect to the abutting portion J by relatively moving along the frictional stirring route set so as to include the joint (boundary line) of the metal elements 10 and 20, and the second tab After continuously stirring the friction to the end position E provided in the part 12, the stirring pin 42 may be detached upward at the end position E. When the rotary tool 40 is rotated and moved along the abutting portion J, the metal of the abutting portion J is plastically fluidized by frictional heat between the rotating tool 40 and the metal, and the abutting portion J is solid-phase bonded. Note that the friction stirring start position S and end position E can be provided at appropriate positions of the first tab portion 11 and the second tab portion 12, respectively, but in this embodiment, on the extension line of the joint of the metal elements 10 and 20. Are provided with a start position S and an end position E. In this way, the friction stir route becomes straight and the moving distance of the rotary tool 40 can be minimized, so that the thermal processing process can be performed efficiently, and further, the wear of the rotary tool 40 is further reduced. The amount can be reduced.

回転ツール４０の形態等に特に制限はないが、本実施形態では、図２に示すものを使用している。図２に示す回転ツール４０は、工具鋼など接合対象よりも硬質の金属材料からなり、円柱状を呈するショルダ部４１と、このショルダ部４１の下端面４１ａに突設された攪拌ピン（プローブ）４２とを備えて構成されている。ショルダ部４１の下端面４１ａは、塑性流動化した金属を押えて周囲への飛散を防止する役割を担う部位であり、本実施形態では、凹面状に成形されている。攪拌ピン４２は、ショルダ部４１の下端面４１ａの中央から垂下しており、本実施形態では、先細りの円錐台状に成形されている。また、攪拌ピン４２の周面には、螺旋状に刻設された攪拌翼が形成されている。   Although there is no restriction | limiting in particular in the form etc. of the rotary tool 40, In this embodiment, what is shown in FIG. 2 is used. A rotary tool 40 shown in FIG. 2 is made of a metal material harder than the object to be joined, such as tool steel, and has a cylindrical shoulder portion 41 and a stirring pin (probe) protruding from a lower end surface 41a of the shoulder portion 41. 42. The lower end surface 41a of the shoulder portion 41 is a part that plays a role of pressing the plastic fluidized metal to prevent scattering to the surroundings, and is formed in a concave shape in this embodiment. The stirring pin 42 hangs down from the center of the lower end surface 41a of the shoulder portion 41, and is formed into a tapered truncated cone shape in the present embodiment. Further, a stirring blade engraved in a spiral shape is formed on the peripheral surface of the stirring pin 42.

回転ツール４０の回転速度および移動速度（送り速度）は、攪拌ピン４２の寸法・形状、摩擦攪拌される金属要素１０，２０等の材質や肉厚等に応じて設定されるものであるが、多くの場合、回転速度は１００〜５０００（ｒｐｍ）の範囲内において、移動速度は２０〜２０００（ｍｍ／分）の範囲内において設定される。また、摩擦攪拌の開始位置Ｓへの攪拌ピン４２の挿入速度（下降速度）および終了位置Ｅからの攪拌ピン４２の離脱速度（上昇速度）も、攪拌ピン４２の寸法・形状、金属要素１０，２０等の材質や肉厚等に応じて設定されるものであるが、多くの場合、それぞれ３０〜６０（ｍｍ／分）の範囲内において設定される。   The rotational speed and moving speed (feed speed) of the rotary tool 40 are set according to the size and shape of the stirring pin 42, the material and thickness of the metal elements 10 and 20 to be frictionally stirred, In many cases, the rotational speed is set within a range of 100 to 5000 (rpm), and the moving speed is set within a range of 20 to 2000 (mm / min). In addition, the insertion speed (lowering speed) of the stirring pin 42 to the friction stirring start position S and the removal speed (upward speed) of the stirring pin 42 from the end position E are also the dimensions and shape of the stirring pin 42, the metal elements 10, Although it is set according to the material such as 20 or the thickness, in many cases, it is set within the range of 30 to 60 (mm / min).

除去工程では、図１の（ｄ）に示すように、金属要素１０と第一タブ部１１との境界部分および金属要素１０と第二タブ部１２との境界部分を切断、溶断等することで、第一タブ部１１および第二タブ部１２を取り除き、金属要素１０，２０を残置する。   In the removing step, as shown in FIG. 1 (d), the boundary portion between the metal element 10 and the first tab portion 11 and the boundary portion between the metal element 10 and the second tab portion 12 are cut, melted, or the like. The first tab portion 11 and the second tab portion 12 are removed, and the metal elements 10 and 20 are left.

以上のような工程を経ることで、摩擦攪拌の開始位置Ｓおよび終了位置Ｅが存在しない金属要素１０，２０の接合体が形成される。なお、得られた接合体に対して切削、研磨、穴あけ、塗装等を施しても勿論差し支えない。   By passing through the above processes, the joined body of the metal elements 10 and 20 without the friction stirring start position S and the end position E is formed. Needless to say, the obtained joined body may be cut, polished, drilled, painted, or the like.

以上説明した第一の実施形態に係る接合方法によれば、一の金属要素１０と第一タブ部１１と第二タブ部１２とが一体成形されており、かつ、これらによって形成された凹部に他の金属要素２０が嵌め込まれているので、第一タブ部１１と第二タブ部１２の横移動をブロック３０，３０で拘束するだけで、金属要素１０，２０の横移動をも拘束することができる。すなわち、第一の実施形態に係る接合方法によれば、別部材のタブ材を突合部の側方に配置する場合に比べて、金属要素１０，２０等を保持する治具等の設置作業を簡略にすることが可能となる。   According to the joining method which concerns on 1st embodiment demonstrated above, the one metal element 10, the 1st tab part 11, and the 2nd tab part 12 are integrally molded, and it is in the recessed part formed by these. Since the other metal element 20 is fitted, the lateral movement of the metal elements 10 and 20 can be restrained only by restraining the lateral movement of the first tab portion 11 and the second tab portion 12 by the blocks 30 and 30. Can do. That is, according to the joining method according to the first embodiment, compared to the case where the tab member of another member is arranged on the side of the abutting portion, the installation work of a jig or the like that holds the metal elements 10, 20 and the like is performed. It becomes possible to simplify.

また、別部材のタブ材を突合部の側方に配置する場合には、タブ材の上面をクランプ等で押さえ込んでも、接合すべき金属要素を押え込むことはできないが、本実施形態の如く一の金属要素１０に第一タブ部１１と第二タブ部１２とを一体成形しておけば、金属要素１０、第一タブ部１１および第二タブ部１２を一括して押さえ込むことが可能となるので、別部材のタブ材を配置する場合に比べて、金属要素１０，２０等を保持する治具等の設置作業を簡略にすることが可能となる。   Further, when the tab material of another member is arranged on the side of the abutting portion, the metal element to be joined cannot be pressed even if the upper surface of the tab material is pressed with a clamp or the like. If the first tab portion 11 and the second tab portion 12 are formed integrally with the metal element 10, the metal element 10, the first tab portion 11 and the second tab portion 12 can be pressed together. Therefore, it is possible to simplify the installation work of a jig or the like for holding the metal elements 10 and 20 and the like as compared with the case where a tab member as a separate member is arranged.

なお、本実施形態においては、金属要素１０，２０が別部材に含まれている場合を例示したが、同一の部材に含まれていてもよい。   In addition, in this embodiment, although the case where the metal elements 10 and 20 were contained in another member was illustrated, you may be contained in the same member.

（第二の実施形態）

The joining method according to the present embodiment includes a joining process (see FIG. 3B), a restraining process, a thermal processing process (see FIG. 4A), and a removing process (see FIG. 4B). ).

突合工程では、図３の（ａ）および（ｂ）に示すように、二つの金属要素１０，１０の各々に他の金属要素２０，２０を突き合せ、その突合部Ｊ１を挟むように第一タブ部１１および第三タブ部１３を位置させるとともに、突合部Ｊ２を挟むように第二タブ部１２および第三タブ部１３を位置させる。具体的には、金属要素１０と第一タブ部１１と第三タブ部１３とで形成される凹部および金属要素１０と第二タブ部１２と第三タブ部１３とで形成される凹部のそれぞれに金属要素２０を嵌め込み、第一タブ部１１の側面１１ｂ、第二タブ部１２の側面１２ｂ、第三タブ部１３の側面１３ｂ，１３ｂをそれぞれ金属要素２０の側面２０ｂに当接させつつ、金属要素１０の端面１０ａと金属要素２０の端面２０ａとを当接させればよい。   In the abutting step, as shown in FIGS. 3 (a) and 3 (b), the other metal elements 20, 20 are abutted against each of the two metal elements 10, 10, and the abutting portion J1 is sandwiched therebetween. The tab portion 11 and the third tab portion 13 are positioned, and the second tab portion 12 and the third tab portion 13 are positioned so as to sandwich the abutting portion J2. Specifically, a recess formed by the metal element 10, the first tab portion 11 and the third tab portion 13 and a recess formed by the metal element 10, the second tab portion 12 and the third tab portion 13, respectively. The metal element 20 is fitted into the side surface 11b of the first tab portion 11, the side surface 12b of the second tab portion 12, and the side surfaces 13b and 13b of the third tab portion 13 are brought into contact with the side surface 20b of the metal element 20, respectively. The end surface 10a of the element 10 and the end surface 20a of the metal element 20 may be brought into contact with each other.

拘束工程では、図３の（ｂ）に示すように、第一部材Ｂ１および第二部材Ｂ２を図示せぬ架台に移動不能に拘束する。本実施形態では、第一タブ部１１および第二タブ部１２の側面にブロック３０を宛がうとともに、金属要素１０，２０、第一タブ部１１、第二タブ部１２および第三タブ部１３の上面の押え部Ｐ，Ｐ，…を図示せぬクランプ等で押さえ込むことで、第一部材Ｂ１および第二部材Ｂ２を拘束する。   In the restraining step, as shown in FIG. 3B, the first member B1 and the second member B2 are restrained so as not to move on a gantry (not shown). In this embodiment, the block 30 is assigned to the side surfaces of the first tab portion 11 and the second tab portion 12, and the metal elements 10, 20, the first tab portion 11, the second tab portion 12, and the third tab portion 13. The first member B1 and the second member B2 are restrained by pressing the presser portions P, P,...

熱加工工程では、図４の（ａ）に示すように、間隔をあけて並ぶ二つの突合部Ｊ１，Ｊ２に対して連続して摩擦攪拌を行う。具体的には、回転させた回転ツール４０の攪拌ピン４２（図２参照）を第一タブ部１１に設けた開始位置Ｓに挿入（圧入）するとともに、挿入した攪拌ピン４２を途中で離脱させることなく相対移動させることで突合部Ｊ１，Ｊ２に対して連続して摩擦攪拌を行い、さらに、第二タブ部１２に設けた終了位置Ｅまで連続して摩擦攪拌を行ったうえで、終了位置Ｅで攪拌ピン４２を上方に離脱させればよい。なお、突合部Ｊ１，Ｊ２の間に位置する第三タブ部１３に対しても摩擦攪拌を行う。すなわち、一の突合部Ｊ１に対して摩擦攪拌を行い、回転ツール４０が一の突合部Ｊ１の終端ｅ１に達したら、この終端ｅ１で摩擦攪拌を終了させずに、隣りに位置する突合部Ｊ２の始端ｓ２まで連続して摩擦攪拌を行い、そのまま突合部Ｊ２に対して摩擦攪拌を行う。   In the thermal processing step, as shown in FIG. 4A, friction stir is continuously performed on the two abutting portions J1 and J2 arranged at intervals. Specifically, the stirring pin 42 (see FIG. 2) of the rotated rotating tool 40 is inserted (press-fitted) into the start position S provided on the first tab portion 11, and the inserted stirring pin 42 is removed halfway. The friction stir is continuously performed with respect to the abutting portions J1 and J2 by relatively moving without any further, and the friction stir is continuously performed until the end position E provided in the second tab portion 12, and then the end position What is necessary is just to detach | leave the stirring pin 42 upwards by E. In addition, friction stirring is performed also with respect to the 3rd tab part 13 located between the butt | matching parts J1 and J2. That is, the friction agitation is performed on one abutting portion J1, and when the rotary tool 40 reaches the end e1 of the one abutting portion J1, the abutting portion J2 located adjacent to the end a1 without terminating the friction agitation at the end e1. The friction stir is continuously performed up to the starting end s2, and the friction stir is performed on the abutting portion J2.

除去工程では、金属要素１０と第一タブ部１１との境界部分、金属要素１０と第二タブ部１２との境界部分、金属要素１０と第三タブ部１３の境界部分を切断、溶断等することで、第一タブ部１１、第二タブ部１２および第三タブ部１３を取り除き、金属要素１０，２０を残置する。   In the removing step, the boundary portion between the metal element 10 and the first tab portion 11, the boundary portion between the metal element 10 and the second tab portion 12, the boundary portion between the metal element 10 and the third tab portion 13 is cut or melted. Thereby, the 1st tab part 11, the 2nd tab part 12, and the 3rd tab part 13 are removed, and the metal elements 10 and 20 are left behind.

以上のような工程を経ることで、摩擦攪拌の開始位置Ｓおよび終了位置Ｅが存在しない金属要素１０，２０の接合体が形成される。なお、得られた接合体に対して切削、研磨、穴あけ、塗装等を施しても勿論差し支えない。   By passing through the above processes, the joined body of the metal elements 10 and 20 without the friction stirring start position S and the end position E is formed. Needless to say, the obtained joined body may be cut, polished, drilled, painted, or the like.

以上説明した第二の実施形態に係る接合方法によれば、金属要素１０に第一タブ部１１、第二タブ部１２および第三タブ部１３が一体成形されており、かつ、これらによって形成された凹部に他方の金属要素２０が嵌め込まれているので、第一タブ部１１と第二タブ部１２の横移動をブロック３０，３０で拘束するだけで、二つの金属要素１０，１０およびこれらに突き合わされる他の金属要素２０，２０の横移動をも拘束することができる。すなわち、第二の実施形態に係る接合方法によれば、別部材のタブ材を突合部の側方に配置する場合に比べて、金属要素１０，２０等を保持する治具等の設置作業を簡略にすることが可能となる。   According to the joining method according to the second embodiment described above, the first tab portion 11, the second tab portion 12, and the third tab portion 13 are integrally formed on the metal element 10, and are formed by these. Since the other metal element 20 is fitted in the recessed portion, the two metal elements 10 and 10 and the two metal elements 10 and 10 can be connected to these by simply restraining the lateral movement of the first tab portion 11 and the second tab portion 12 with the blocks 30 and 30. The lateral movement of the other metal elements 20 and 20 to be abutted can also be restricted. That is, according to the joining method according to the second embodiment, compared to the case where the tab material of another member is arranged on the side of the abutting portion, the installation work of the jig or the like for holding the metal elements 10, 20 and the like is performed. It becomes possible to simplify.

また、別部材のタブ材を突合部の側方に配置する場合には、タブ材の上面をクランプ等で押さえ込んでも、接合すべき金属要素を押え込むことはできないが、本実施形態の如く金属要素１０、第一タブ部１１、第二タブ部１２および第三タブ部１３を一体に成形しておけば、金属要素１０、第一タブ部１１、第二タブ部１２および第三タブ部１３を一括して押さえ込むことが可能となるので、別部材のタブ材を配置する場合に比べて、金属要素１０，２０等を保持する治具等の設置作業を簡略にすることが可能となる。   In addition, when the tab material of another member is arranged on the side of the abutting portion, the metal element to be joined cannot be pressed even if the upper surface of the tab material is pressed with a clamp or the like. If the element 10, the first tab portion 11, the second tab portion 12, and the third tab portion 13 are formed integrally, the metal element 10, the first tab portion 11, the second tab portion 12, and the third tab portion 13 are formed. Since it is possible to press down all together, it is possible to simplify the installation work of a jig or the like for holding the metal elements 10, 20 and the like as compared with the case where a tab member of another member is arranged.

なお、図示は省略するが、第三タブ部１３のみを金属要素１０と一体成形しておき、第一タブ部１１および第二タブ部１２を別体としてもよい。   In addition, although illustration is abbreviate | omitted, only the 3rd tab part 13 is integrally molded with the metal element 10, and it is good also considering the 1st tab part 11 and the 2nd tab part 12 as a different body.
