In other words, the lock ρ2 (see Fig. 4(4)) of the splicing rotary tool F of the splicing of the splicing of the splicing of the splicing of the squirrel is moved to the end position & Further, in the second embodiment, the start position Spi of the friction stir is set on the first protruding material 2, and the end position Ερι is set on the young-projecting material 3, but the positions of the start position ^ and the end position Ερι are not limited. . Further, in the present embodiment, is the dummy tool used by the dummy? And the rotation direction of the joining rotary tool G is all right-handed. Thus, the work procedure can be omitted by matching the rotational directions of the dummy joining rotary tool F and the joining rotary tool G. The order of the friction (4) in the first preparatory work of the present embodiment is explained in detail with reference to Figs. 5 and 6. First, the joined metal member subjected to the pseudo welding process is ligated to a gantry of a friction stirrer (not shown). Then, as shown in Fig. 5(a), the dummy joining rotary tool F is positioned directly above the start position Sn of the appropriate position of the first protruding member 2, and then the dummy joining rotary tool F is rotated to the right. When it is lowered, the stirring pin F2 is pressed into the starting position Sp]. The rotation speed of the dummy joining rotary tool F is set in accordance with the material and thickness of the metal member 1 to be joined, such as the size, shape, and friction stir of the mixing lock F2, but in many cases, it is set to 500. ~2〇〇〇(rpm) in the range of 2 25 2036-9894-PF; Chentf 200906525 When the sandalwood pin F? _ poor ^, Ζ and the surface of the first dog 2 is in contact with the surface 22, The metal plasticizing flow around the pin F2 is inserted into the first protruding material 2 as shown in Fig. 5(b). After the entire length of the pin F2 is inserted into the first protruding material 2 and the lower end surface FU of the shoulder portion F1 is in full contact with the surface 22 of the first protruding material 2, as shown in the first drawing, the false joining rotary tool F is rotated. The side is like the first protruding material. The starting point s 2 of the work is relatively moved. -r, the speed of the teeth, and the "this degree" are set obliquely to the size of the stirring pin F2, the #处 対 y, and the material and thickness of the joined metal member 1 for friction stir, but most of them are used. In the case of the case, it is set in the range of _ two wide: minute). The rotation speed when the dummy engagement is moved by the rotary tool is the same or lower. In addition, it is slightly inclined that the axis of the forward shoulder F1 is opposite to the wrong straight line and the side of the square is slightly inclined, and if it is not inclined, it is in the direction of the wrong tool 1^ σ Use the rotary tool F to move 0± 复杂 complex motion. The metal around the pseudo-productive door, &quot;2, is sequentially plasticized, and at the same time, the metal is separated again from the sandalwood F2. The plastic flow makes the false joint use the rotating tool F The starting point s2 of the frictional large-outlet joining project is performed until the second protruding material is connected to the mixing, and the false joining rotary tool F &quot; is used at the starting point. The second protruding material is joined to the second protruding material bonding work. The first protruding material and the joined (2)) first protruding material joint works in the first protruding material joining project 2036-9894-PF; and the Chent 200906525: the protruding portion J2 of the metal member 1 performs friction stirring. Specifically, Setting the route of the friction stir is set on the joint (boundary line) of the joined metal member 第 and the -= output 2 'by making a false joint along the path:

Rework: For relative movement, friction stir is applied to the joint J2. Further, in the present embodiment, the dummy joining rotary tool F is prevented from being separated from the first projecting material joining work 32 to the point e2, and the winter point e2 is continuously subjected to friction stirring. Further, the dummy joining rotary tool F is rotated rightward, and the false joining rotary machine is F. The dry pushing pusher of the false joining machine F is slightly smaller than the left side of the binding direction of m, so the most It is good to set the position of the first protruding material to the d and the end point e2, and the α (four) starting point rotation 1 F m piece 1 is located on the right side of the false joint production t: direction. In this way, it is difficult for the void defect to occur in the joint body in which the joined metal member is difficult to be fired.

, § Make the fake joint rotation tool F with the Rotary Worker F as the traveler A 疋轱扦, since the right side of the stapling direction of the J-joining direction will be generated, it is better to set the first protrusion and the second hole defect. The position is such that the start and end points of the connected project are connected to the left side of the hypothesis &amp; Specifically, the line of #F is placed in the dummy joining rotary tool F as the dry 1 but the starting point p9 y when the starting point is set and f is the right-handed turning is placed in the false joint rotating machine and F, When the joint pin (J2) of the rotary tool F is used as the dummy joint F, the metal member i is joined to the first a. #生作用, because the metal member of the joined metal plate:: pulled away from the inner corner 2a, 2b (refer to the first benefit: the formation of the 2, the brother 2 picture) hunting by welding to make the metal 1 and The first protruding material 2 is smashed, and no opening is formed between the connected Z. 2036-9894-PF; Chentf 21 200906525 (2 - 2) False joint engineering rotary joint rotary tool F » e2 broadcast, after the end point of the Dali two protruding material joint project, at the end point e2 frictional surname, , "See the end of the mixing and the continuous holding of the friction until the starting joint 1τ, work 鋥.gp μ point S1, and move to the false joint work in this state, that is, the first - protruding material joint I γ The starting point, off.

Chentf 2 03 6-9894-pp; 29 200906525 - The starting point s3 of the projecting joint project and the positional metal member 1 of the end point e3 are located in the traveling direction of the false joint rotating guard F, and the mouth is also used as a false joint rotating tool F Stirring pin:. In the case of J3, although the force of the metal member to be pulled into the dog 3 is removed, the metal member i and the inner corner portions 3a and 3b of the first member are engaged. Only in the shape of 3, the younger brother 2 shows that no fine holes are formed between the joined metal 1 and the first protruding member 2 by welding. 5th stomach "3 at::::: the turning tool F reaches the end of the first-bend (four) joining project = after the end of the end of the friction welding is not finished and the friction stir is continuously performed until the end of the first protruding material 2 Bit ^^ ^ and 1^1. Moreover, in this "in the case, on the surface of the joined metal member 1", the junction of the joint (boundary line) is provided on the extension line of the P ^ r 罝 η η °, that is, the end position W is the start position Smi of the smear in the first joining work to be described later. After the dummy joining rotary tool F reaches the gentleman's de-phased dyke', the beam position EP1, the dummy joint 5 is made. Rotate the edge of the rotating tool F and the EP1 is detached. See the end position of the F2 at the mixing steel, although the first protruding material is connected to the σ work, the fake joint project is explained by the brother's large-scale joint project. The execution in the joint project is only a case of a cow, and the trajectory of other forms can also be used. The pick-up and the omission of the first protruding material joint project and the second protruding material joint work can also be performed. The project is followed by the implementation of the formation of the lower hole. Next ~... Tear - eight The forming process is as shown in Fig. 4(b), which is the starting position of the stirrer in the first joint project, 30 2〇36-9894-PF; and the Chent 200906525 into the lower point pi. *In the lower hole forming process in the preparatory work of the 篦一猫柱, the lower hole is formed on the surface 32 of the second protruding material 3. The purpose of the lower hole P1 is to reduce the rotating tool for the joint. In the present embodiment, the insertion hole (the press-in impedance) of the mixing pin G2 is not shown in the drawing when the release tool (4) is used to release the pin and the fourth pin (a) is disengaged. The drilling tool is formed by reaming. If the hole M' is used, the working time of the lower hole P1 can be simplified, and the working time can be shortened. Although the shape of the lower hole Pi is not particularly limited, in the present embodiment, the cylinder is Further, in the present embodiment, the position of the lower hole P1 is not particularly limited in the formation of the lower hole P1 in the second protrusion 3, and the first protrusion 2 may be formed in the protrusions j2 and J3. Preferably, the present embodiment is formed on the surface A side of the joined metal member 如In the present embodiment, the stirring pin F2 of the dummy joining rotary tool F (see FIG. 4(a)) is pulled out. For example, the case where H1 is reamed to form the lower eight P1, the maximum outer diameter L of the stirring pin F2 is smaller than the minimum outer diameter m of the joint rotating tool G (four), and the maximum outer diameter 授2 of the pin 2 is changed. The maximum outer diameter γ2 of the mixing pin of the joining rotary tool G is still small (y3&lt;X2&lt;Y2W, the lower hole P1 of the stirring pin F2 can still form the lower hole P1. (3) The first joining project The joint work is a process of actually joining the joint portion J1 on the surface a side of the joined metal member 1. In the first joining process of the present embodiment, 'the jointing rotary tool G shown in Fig. 4(b) is used, and the joint portion in the state of 2〇36-9894-PF;chentf 31 200906525 is falsely joined. u

The side is subjected to friction stirring. The surface A of the σ metal member 1 is in the first bonding process, the female hole Pi, the inserted stirring pin G2 纟, the lower em of the starting position h, that is, 'in the first-joining project, moving from the bottom to the end Position and continue to carry out the stirring of the joints. The eight-P1 starts the friction stir and the 'hand' is stirred until the end position Ei&quot;. In this case, in the preparatory work of the younger brother, the frictional point of the rotary tool F is used. ^ The material and the agitation device are located directly above the gentleman of the second projecting member 3 (refer to Fig. 6). If the first position of the first jointer is S»n, the friction of the joining tool and the turning tool G is provided. When the stirring device is not moved, the first-stage joining process is performed, and the work can be omitted. Further, in the present embodiment, the second protruding material 3 is provided with the start position SM1 of the frictional drop and the end of the first projecting material 2 is completed. The position Ε»π' is not limited to the position of the start position Sm1 and the end position &amp; The first joint project will be described in more detail with reference to Figs. 7a to 7(c). First, as shown in Fig. 7(a) , so that the joining rotary tool g is located at the lower hole P1 (starting position SS Immediately above M1), the joint rotation tool G is lowered while rotating to the right, and the front end of the stirring pin is inserted into the lower hole. When the stirring pin G2 enters the lower hole P1, the circumferential surface of the stirring pin G2 (side) Abutting against the wall of the lower hole P1, the metal starts to plastically flow from the hole wall. When this state is reached, the plasticized flowing metal is pressed back on the circumferential surface of the stirring pin G2, and at the same time, the feeding lock G 2 is pressed in. The press-in impedance at the initial stage of press-fitting can be reduced, and the shoulder G1 of the joining rotary tool G abuts the table 2036-9894-PF of the first projecting member 2; before the face 22 of the Chentf 32 200906525, the stirring pin G2 abuts on the lower eight P1 to generate frictional heat.

It can be shortened to the time of plastic fluidization. U, that is, reducing the load of the friction stirrer, and shortening the working time required for the joining process. After the entire length of the mixing pin G2 enters the second protruding member 3 and the shoulder portion is in contact with the surface 32 of the second protruding member 3, as shown in the seventh figure (8), the bonding is performed while rubbing (four) The turning tool g relatively moves toward one end of the joint of the joined metal member 1 and traverses the protruding portion J3 to protrude into the protruding portion η. When the joining rotary tool G is moved, the metal surrounding the mixing pin is plastically fluidized in order, and at the same position separated from the stirring pin G2, the plastic fluidized metal is hardened again to form a plasticized region (hereinafter referred to as " Surface-side plasticized areas"). Further, the plasticized region includes a state in which it is plasticized by the frictional heat of the rotary tool and a state in which the rotary tool passes through and is in the state of f. The moving speed (transport speed) of the joining rotary tool G is set in accordance with the size and shape of the stirring pin G2, the material and thickness of the joined metal member 1 such as friction stir, and the like. However, in many cases, the setting is set. Within the range of 30 to 300 (mm/min). When the amount of heat entering the joined metal member 1 is excessively large, it is preferable to supply water from the surface a side around the joining rotary tool G to be cooled. Further, when the cooling water enters between the first metal member 1a and the second metal member 1b, 'there is an oxide film on the joint surface (refer to the end faces lib, lib, and 2(b)). In the meantime, since the hole between the joined metal members 1 is closed by the dummy joining process, it is difficult for the cooling water to flow between the joined metal members 1, and the quality of the joint portion is not deteriorated by 2036-9894-PF; and Chentf 33 200906525. The joint portion 1 of the joined metal member is set on the path trajectory set on the joined metal-wedge #), and the joint is used (the movement in the false joint project is from the two ends Γί with the rotary tool G) The frictional agitation is performed by relatively moving the joining rotary tool to the same position. The friction stirring is simultaneously performed at the end of the transverse _protruding m. [&quot;2' is in this state toward the end position EM1 and, in the poor In the embodiment, the start Sm of the friction search is set on the extension line of the joint (boundary line) of the joined metal μ| 1 on the surface A side of the joined metal piece, and no component i is mixed. The path of the first joint project is effective, and the efficiency of the first joint work is effectively eliminated, and the distance between the transfer and the distance of the G is minimized. The amount of wear of the rotary tool G can be reduced. _ When the splicing tool is rotated and the slewing gear G reaches the end position Em], if the rotary tool g is rotated, the rotation is raised, and the money is transferred from the end position. According to the first touch)). Further, at the position Emi, if the m 抹 Γ 为 为 为 G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G G Preferably, the rotational speed of the engagement rotation (the rotational speed at the time of disengagement) when the agitating pin G2 of the %-turning tool G is disengaged from the end position EM1 is higher than the rotational turbulence during the movement. In this way, compared with the case where the rotation 2037-9894-PF at the time of disengagement and the rotation reading p degree of the moving pin 2 is the same as the case where the rotation of the stirring pin 2 is small, the end position can be made k. :.»&quot; The separation of the mixing pin G2.第一 Prior to the first joint project, the first preparatory work was carried out. In the meantime, the first preparatory work was carried out and the first joint work was carried out directly after the first preparatory work. (4) Second preparation project. In the second preparatory work, the quasi-injury performed before the second pre-injury project has a re-installation project in the present λ palladium form, and the inner side of the joined metal member 1 is turned upwards and is again provided in the unillustrated Friction stirrer. (4~1) The member to be joined is re-installed, and the first joint is released, and the joined metal member 1' is again placed on the rubbing 1 as shown in Fig. 1 so that the joined metal member 1 is connected. In the joining member re-installation project, the front and back of the joined metal member 1 of the project are reversed, and the inner side of the joined metal member 1 is placed on the gantry. In the present embodiment, the metal fitting member 1 is half-rotated on the front and rear axles, and the front and back are reversed. Here, Fig. 8(a) is a cross-sectional view taken from the protruding portion η李月 toward the first metal member side after the second installation of the first preparatory work. As shown in Fig. 8(a), in the re-installation process, the upper surface of the joined metal member 1 becomes the inner side B, and the second protruding member 3 is formed from the side of the protruding portion j丨 toward the first metal member 1a. Located on the lu side of the joined metal member, the first projecting member 2 is located on the right side of the joined metal member 丨. 2036-9894-PF; Chentf 35 200906525 Item 1 = Bundle: The form of the friction stirrer, which rotates the watch without releasing the restraint of the joined metal member 1.
