Description of the invention: [Technical field to which the invention pertains] Method and apparatus for joining metal sheets The present invention relates to the use of friction pressure joints. [Prior Art] Friction-bonding and friction (F) coupling f (FnCtlon Stlr Welding, F s w ) are well known. These are solid phase bonds. The solid phase bonding method utilizes the relative motion between adjacent surfaces to engage the material. Friction crimping has the problem of solving the welding method that has been performed in the past. For example, in arc welding, the strength of the base material is reduced due to melting of the welded portion, resulting in a decrease in the strength of the base material around the material portion, and the defects of the (4) angry hole or the solidified turtle material. Further, in such a joining method, there is a problem that the heat-dissipating property is hindered in the bonded portion, and the heat-dissipating property is hindered. 〇 / / In order to solve these problems, there is the development of friction crimping method = the manufacturing method of various components of the friction and compression method (patent literature... this is made of metal on the surface of a thin metal plate) When the connecting member is pre-welded, it is also used by the crimping method (the patent document is small, and the pin-shaped metal joining member is joined to the metal plate-shaped base material, and the wooden welding method is used. However, if the sound tube of the plate-shaped base material has a connecting member having a larger diameter than the base material, the J-cavity of the solidification shrinkage after the splicing may occur on the back surface of the joint portion of the surface of the surface, or Harmful thermal deformation occurs. In this case, the plate-shaped 316918 5 IDDJLJl base material is formed by joining the convex portions. The friction crimping is also performed by connecting eight widths to 1 to solve the conventional problem. It is difficult to melt the material and the material of the different materials (4). ===== But the steel is spliced to the friction of the ceramic; ^ γ > , /, · between the steel and the phase roller Manufacturing: Text: ':^ There are also materials that make the joint processing _ face, insert more Material: = direction, the joint (probe) in the abutting state is rotated, so that the cylindrical rotation made by 1 kg is ^^3, so that the circumference of the joint surface of the relative contact is added. The figure is described in detail. The part of the joint surface 24 and the peripheral portion thereof are heated and melted by the frictional heat generated between the plate and the plate by the rotation of the circular rotor to join the plates. The body rotator is attached to the cylinder. The tip end of the rotor body 25 is a large rainbow. Further, the friction stir probe 21 having a small needle shape is formed in the shoulder portion: the one plate member 22 and the other plate member 23 are formed, and The rotating sub-body rotates by rotation and moves along the joint surface 24. The probe is moved along the joint surface of the opposite surface of the plate to generate frictional heat to soften and plasticize the portion. Since the shoulder 27 rotates, the shoulder 27 and The frictional force generated between the friction stir mixing probe 21 and the plate material (22, 23) causes the plate material 23 to have a compressive stress 30 due to the cylindrical rotor, and the plate 22 A is now caused by the rotation of the needle. Compressive stress 3 work. This method is used to The different materials with different deformation resistances 6 316918 1335251 _ Ren Yin's difficulty in peak position or temperature control, a slight deviation is difficult to deform different materials of high melting point 'On the other hand only different materials with low melting point The case of deformation occurs, and as a result, (4) is insufficient and there is a problem that sufficient bonding is not obtained. σ β In this way, two sheets of the overlap are bonded. In this case, the portion of the weight f becomes the joint surface. The sheet material 29 is overlapped with the upper sheet material, and the surface of the joined portion of the upper sheet is inserted into the side of the joint portion of the upper rotating rod, and the two sheets joined by the rubbing and stirring are added to the portion to be joined (Patent Document 7 and Patent) Document 8, Patent Document 9). These methods are in accordance with the aforementioned friction stir welding method. It is illustrated in Figure 8. The lower sheet 29 is superposed on the underside of the upper sheet 28 to join the overlapping portions. This method is also used at the top of the cylindrical rotating body 2 (), : = = a small diameter of 2 rounds of the needle diameter of the needle - the probe body dog is set to the coaxial. Then, the portion of the root portion 27 of the probe 21 is brought into contact with the upper plate member 28, and the rotary sub-body is rotated by rotation. The tip of the needle is delivered to the access surface of the upper plate 28 and the lower plate (9). The point at which the joint surface is directly rubbed and melted is close to the aforementioned method. The generated frictional heat plasticizes the portion of the boundary portion and the probe of the upper plate. Insert the friction stirrer probe 21 into the upper plate, and then connect the part (4) to the upper plate, and expand the field to make the joint A strong = part of the friction stir is included: 4 Therefore, the scope of melting has also expanded. Therefore, the burrs are produced, and the joint surface becomes rough. In addition, the friction required to be used is 316918 7 1335251 'The rotating member is pressed on the surface of one of the plates, and the friction heat generated by the rotary mill is used to levy the metal of the overlapped plate. Invention of the method of joining the plates (10) Patent Document No. 3 of the Hi-H Temple is explained. The cylindrical rotating member 1 frictionally rotates the surface of the upper plate 6 in the overlapping sheets 7. 'When the rotating member is pressed against the surface of the sheet, the scraping joint method is used to search for the friction of the needle with a smaller diameter: for example, the operation of the sheet and the shoulder is rotated in depth to the inside of the sheet. The "columnar rotating member 1" enters the upper plate and the lower plate:: The frictional joining method only makes the surface of the plate plastic, and when the rotating member (4) is applied to the plate 6, the concave portion 9 occurs. Concave:; Formed by =::4 with two plates of overlapping overlap. The cylindrical rotating member 1 is characterized by the method of moving the upper plate, and the joint strength of the above-mentioned frictional bonding, and in addition, the joint of Qiu has been sufficiently reduced, and J is small, and the joint portion is confused. , less power required. And the device is not big. Therefore, the occurrence of the burrs is less than the friction (4) joint method. If there are many advantages.

However, it is necessary that the portion is not completely embedded in the sheet card 0. The portion of the cylindrical or semi-conical portion 4 is pressed into the one of the sheets, and the top portion of the cylindrical portion forming the flat shape is retained between the top sheet and the one of the sheets. The state of the gap 5 is required. With the rotation of the cylindrical rotating member, the cylindrical or semi-conical shape = the burr generated by the friction with the sheet occurs in this portion of the clearance. Specifically, the portion of the cylindrical or semi-conical portion 3 of the aforementioned cylindrical rotating member that comes into contact with the sheet material and its vicinity are burred along the cylindrical or sheep conical shape. The resulting burrs are formed in a portion directly below the cylindrical rotating member and are cut by the corners of the rotating cylindrical rotating member. As a result, the burrs are cut off to form a smooth joint without burrs (Fig. 2). Once the gap is set to a fixed value, the occurrence of the burrs generated is not uniform, and the gap can be appropriately determined by the μ # experiment according to the operating conditions such as the joining speed. After that, the relationship between the tensile shear strength of the aforementioned frictional crimping and the depth of pressing is known as the following. The tensile shear strength of the joint tends to increase with the indentation depth of 2 plus =. Therefore, the depth of the waste person reaches a certain range - the range of the strong translation tensile strength is also maximized, even if the depth is increased, but the Mou 2 2: that is, 'this - fixed indentation depth treatment' can be obtained - according to The maximum value of the tensile strength. According to the present invention, == is affected by the joining speed condition, but is deep by the surface; as long as it is 0.3 or more, the tensile shear strength 316918 12 1^35251 is constant. This tensile shear strength is then maintained to 〇.5 (i.e., the thickness of the upper plate). It is known that the depth operation of this level is better than 22). The Lechuan friction method is used to join the plates formed by the two plates of the upper plate and the lower plate. The inventors of the present invention have found that the friction bonding method can also be applied to the joining of a combination of two sheets of the upper plate and the lower plate. As a result, the new method of picking up another sheet of metal between the top and bottom sheets of the two sheets (four) is called a blame. According to this method, it is possible to laminate a metal plate having other characteristics between the metal plates. Therefore, it is possible to laminate a material having conductivity in the intermediate portion, and various kinds of articles can be developed therefrom. The inventors of the present invention have completed the following invention based on the above findings. x That is, according to the present invention, the following invention can be provided.

This material - the body former. The ratio of the diameter of the cylindrical rotating member to the diameter of the circle of the planar shape is the same as that of the straight line 1 and can be appropriately determined. In the present embodiment, the outer diameter of the circle of the cylindrical rotating member is 15 coffee, and the outer diameter of the circle of the cylindrical or semi-conical 3 is 1 〇 to 6 _ to obtain good results. These values can be used as reference values. 'Investigating the tensile shear strength and the indentation depth by the aforementioned frictional crimping, the following facts can be known. # #合部's tensile shear strength has a tendency to increase with increasing penetration depth. Then, when it reaches a certain penetration depth, the tensile shear strength reaches its maximum, and thereafter the strength does not increase even if the depth increases. That is, the maximum anti-shear strength of the friction crimping can be obtained by simply treating the dust into the depth. According to the experiment of the present inventors, the depth of the surface is about 0.2 or more, and the depth of the surface is 0.2 or more. When the thickness is determined to be 〇3 or more, the tensile shear strength reaches a certain value. Then, the tensile strength of this pull will be maintained to 〇.5 (ie the thickness of one half of the upper plate). It is thus known that the three-indentation depth operation is preferred (Figs. 2 to 22). Hereinafter, specific contents are shown by way of examples. - Fig. 4 is an example of an entire apparatus which does not have the above-described cylindrical rotating member of the present invention.

Si 3 = ^ When the frictional pressure of the composite material and the SPCC steel plate is the same as that of the other steel plate, it can be tested; ^t is not limited to this example. It is not limited to this specific example. In addition, the characteristic 'is performed in the same way.

Next, when the press-in depth is 0.2 mm, the tensile shear strength is about 7.OkN, and at 0.3 mm, it is 7.2 kN, and the tensile shear strength at 0.5 mm is also 7.2 kN. Similarly, at a joint speed of 0.4 mm/s, the tensile shear strength was 7.2 kN when the depth of penetration was 0.1 mm. Secondly, when the indentation depth is 〇.2mm, the tensile shear strength is approximately 7.2kN, 7.3kN at 0.3mm, and the tensile shear strength at 0.5mm is also 7.2kN. At a joint speed of 0.6 mm/s, the tensile shear strength is 3.6 kN when the penetration depth is 0.1 mm. Secondly, when the penetration depth is 0.2 mm, the tensile shear strength is 4.5 kN, and then 0.3 mm is also 7.2 kN, and the tensile shear strength at 0.5 mm is also 7.2 kN. 0.8mm/s • The tensile shear strength - 5.OkN at a penetration depth of 0.1 mm at the joint speed. Secondly, when the press-in depth is 0.2 mm, the tensile shear strength is 7.OkN, and after 0. 3 mm, it is also 7. 2 kN, and the tensile shear strength at 0.5 mm is the same 7.2 kN. At a joint speed of 1. 0 mm/s, the tensile shear strength is 2.2 kN when the penetration depth is 0.1 mm. Secondly, when the depth is 0.2mm, the tensile shear strength is 7.OkN, and after 0.3mm • the same is 7.3kN. The tensile shear strength at 0.5mm is the same 7.2kN (above, refer to Figure 20). From this, it is found that when the press-in depth is 1/2 of the plate thickness, that is, 0.5 mm, the tensile shear strength is approximately the highest value. Further, although it varies depending on the joining speed, when the press-in depth is 1/5 of the sheet thickness, that is, 0.2 mm or more, the tensile shear strength and the tensile shear strength at a press-in depth of 0.5 mm are obtained. In comparison, it becomes a very high value, and when the indentation depth is 3 316, which is 3, or 0.3 mm, the thickness of the tensile strength is approximately the same as the tensile shear strength when the depth of penetration is 〇.5 mm. From the above, it can be seen that the press-in depth is at least 2/10 of the sheet thickness, more preferably 3/10 or more of the sheet thickness, and the maximum is 5/10. The same test was carried out for different materials (a combination of 5052 aluminum alloy and 2017 aluminum alloy) with a thickness of 1 mm. The result is shown in Fig. 12. Under the joint speed of 0.2 mm/s, the tensile shear strength is 7.OkN when the penetration depth is 0.1 mm. Secondly, when the press-in depth is 0.3 mm, the tensile shear strength is about 7.0 kN, and 6.8 kN at 0.5 mm. Similarly, at a joining speed of 0.4 mm/s, the tensile shear strength was 6.3 kN when the indentation depth was 0.1 mm. Secondly, when the press-in depth is 0.3 mm, the tensile shear strength is about 6.OkN, and the tensile shear strength at 0.5 mm is also 6.4 kN. At a joining speed of 0.6 mm/s, when the indentation depth is 0.1 mm, the tensile shear strength is 3.OkN. Secondly, when the indentation depth is 0.3 mm, the tensile shear strength is 7.OkN, and the anti-luera shear strength at 0.5 mm is also 7.OkN. At a joining speed of 0·8 mm/s, the tensile shear strength was 3.9 kN when the indentation depth was 0.1 mm. Secondly, when the pressing depth is 0.3 mm, the tensile shear strength is 6.3 kN, and the tensile shear strength at 0.5 mm is also 6.2 kN. At a joint speed of 1.0 mm/s, when the press-in depth is 0.1 mm, the tensile shear strength is 6.2 kNW. When 3 mm, the value is 6 · OkN or more, and at 0.5 mm, the tensile shear strength is approximately the same. The value of 6.OkN or more (above, refer to Fig. 21). From this, it is known that the tensile shear strength is approximately the highest when the indentation depth is 1 / 2, that is, 0.5 mm.
