Description of the invention: [Technical field to which the invention belongs], friction surfacing method, metal laminate The present invention relates to a method for manufacturing friction surfacing rod plates and metal laminates. -[Prior art] The joining method of the components from the state P is a method of joining the components of the object to be joined, and the rotational heat, plus the wishing method is the frictional heat of the friction surface of the heart to add time, Kao'an is well known. Welding different kinds of metals: considering the base material, the welding material is stacked, and the friction welding rod is rotated to contact the bad connection part to form the surface modification used by the tool. . This method has also been published by the present inventors in the previous two days (Japanese version, Hei 9/262688). = The surface of the plate 'is friction-welded with Ming or Shao alloy to form a joint. == and to—to form a plate or t product = (Patent Document 2 Japanese Patent Application Laid-Open No. 11315). Also, when forming the friction surfacing layer, shoot on the surface of the product, and then friction surfacing on the formed, Xuanshi Besch / Valley surfacing to form a hard ^ and Japanese Patent Laid-Open No. 1G · 15675 Bulletin). When friction surfacing is performed on the surfacing, the f 堆 ^ and so on will be A. Moreover, the welding height is also uneven. In order to solve this problem, a groove is provided and the diameter of the rod is used. 316917 5 200539975 ^ This method is disclosed in the patent gazette (Patent Document 4 JP 2000-1Π464, special thorn + such as, side- 0). Also, make ^ Japanese special, then, add salt. Add ^ Chin alloy rods to increase friction pressure =; and from the viewpoint of reliability, define the technology of titanium rods or Chin alloy cups (patent wire 6 Japanese rule _ 1 The component material is not melted and the dilution is small: == modification technology ', and the formation of a thick film layer is also easy. For: t: t = feasible method, about this the inventor has been good before The development of the bucket method and the wood material [non-reading summary of the rejuvenation conference lecture, (2000), 283]. It belongs to the first "%" m friction overlay welding 'for the friction overlay welding material to be good _ uniform hook adhesion' How to design the friction surfacing material = or shape 'has not been fully reviewed so far. That is, the research results are still needed to confirm the material-like friction surfacing society structure or development. Both the width or thickness of the welding ^ make friction surfacing more effective, and can be used for subsequent processes such as rolling. Good for the above reasons' can make the width of friction surfacing or The thickness-average friction surfacing method is yet to be developed. [Patent Document 1] Japanese Patent Publication No. 2626 Japanese Patent Publication No. 88 [Patent Document 2] Japanese Patent Publication No. 2003-311315 [Patent Document 3] Japanese Patent Publication No. 10-15675 [Patent Document 4] Japanese Patent Publication No. 2000-117464 [Patent Document 5] Japan Japanese Patent Application Laid-Open No. 20001-138〇7〇 316917 6 '200539975 [Patent Document 6] Japanese Patent Application Laid-Open No. 2003-1424 [Non-Patent Document 1] Outline of the 98th Spring Conference of the Light Metal Society, (2000), 283 [Summary of the Invention], (Problems to be Solved by the Invention) The problem of the present invention is to provide a new friction surfacing rod, a new friction surfacing method using the new friction surfacing rod, and the use of the new friction surfacing. Welding rod metal laminated board and manufacturing method of metal laminated board. (Means to solve the problem) ^ The inventors have observed the frictional crimping between the tube and the board and observed its progress. According to the results of this observation, it was found that the joint The burrs only occur on the tube side, and the burrs are almost invisible on the plate side. It is also found that the burrs are discharged inward and outward in the same situation as when the tube is joined to the tube, and the burrs on the hem are larger than the burrs on the outside. 'And inside and outside hair The edges have a tendency to increase the burr over time (Light Metal 4) Vol., December (1991), p. 81. These cognitions are about friction welding, and the operation of welding with friction. Obviously, it is different, so from the above result, 'It is impossible to judge what kind of space-time result will be caused by the material welding towel.' # In the past, friction cylindrical welding rods used solid cylindrical ones. The inventor's temple added the above problems. After careful research, it was found that surfacing welding is carried out: in the method of friction surfacing welding in contact with the surface of a metal plate in a rotating state, if it is made into a hollow rod-shaped rod, unexpectedly, it can be uniform. Since the surface of the rod-shaped friction surfacing is friction surfacing, and in the middle == state, the metal plate is used in the middle trowel, and it is rolled in the friction surfacing. 316917 7 200539975 The surfacing welding material can be used as friction again. The fact that surfacing materials are used helps to form a wasteless surfacing. ', Good results for Zhao Ru H, even with the above-mentioned cognitions of the present inventors ...,' are unexpected discoveries. • Using this new discovery, you can make the previous friction pile better. When friction surfacing is performed on a plate formed of sheet metal material, the friction surfacing rod used may be the same metal material as the above plate, and the same metal material. The method of applying friction ^ on the surface of the metal plate can be used for the friction stack of the metal surface or the repair of the high-ink treatment device or the reaction device. The metal plates that have been subjected to this friction surfacing can be scrapped in the heat to produce metal laminates. The metal laminated board obtained in this way has a thin structure in the welded part and the base part, and the center of the welded part can be recognized in the metal laminated board due to the difference between the stack and the dried seeds before rolling. The thickness of the stacking portion is accounted for, and the ratio of the thickness of the overlaying layer to the thickness of the base material is approximately the same. 获 Get: Yes, the bonding surface of the metal plate is closely attached without organizational chaos. Good bonding means. According to the tensile strength test of the metal laminated board = 4 of the metal laminated board, the result of the plastic deformation ratio U flange rate ^ The second series can fully meet the results. As a result of these results, according to the present invention, the Mona laminates' can be added with inherent properties. That is, it is possible to give different characteristics of metal to the surface and the back of the metal laminate. In this case, the respective degrees of the metal plate formed on the surface and the metal plate formed on the back side can be appropriately adjusted. With this feature, a thin and hard surface can be formed on the surface ^ and a thick and soft inner layer can be formed on the moon surface. For example, it can be made of aluminum alloy 316917 8 200539975 = al_n) to form a hard and thin skin layer, the same as the color or light manufacturing = non-layer metal plates with available material characteristics, ^ laminated plates with different ratios . It is also possible to manufacture metal plates with complicated characteristics by manufacturing multiple i-plates to make the interlayer between the skin and the metal plate on the back or back. Up to. According to the present invention, the following inventions can be provided.摩擦 Frictional overlay welding rods characterized by hollow rods. (2) On the surface of the metal plate, contact the welding rod in the rotating state with the welding rod of all the plates. In the method of *, use one of the following items: the friction welding rod formed, in The surface of a metal plate is known as a friction surfacing method in which a metal 1 motor is stacked. 3 (3) Touch the friction pile cup formed by the rod of the patent application item Yu Pf, and the king of the king to contact the surface of the metal plate in the state of ㈣, in order to start the operation at τ 隹, 廿The metal surface is collected, and the surface is damaged, and the metal surface of the friction surfacing is reported as a metal laminate. (4) Contact the metal plate with the friction pile formed by the ^ ^ η ^^ and the work object in the first scope of the patent application *, "## ::: in the metal plate" Product :::::::: Metal "Yu_place (effect of the invention) According to the present invention, because of the use of six types in the class ~ ±, the social fruit of the column-shaped friction surfacing rod with τ work can be used. Perform uniformly and with good efficiency 4… metal surface or high μ treatment device or reaction device ° Wood is used as a surfacing metal plate and hot rolled repeatedly to make the entire ° can be used to make the friction clothing into a mongolian laminated board. For 316917 9 200539975 metal laminates, the overlay structure and the substrate part show a fine structure. The center of the overlay structure can be appropriately adjusted according to the thickness of the overlay before rolling, and can be made. Metal laminate with characteristics of the constructed metal plate [Embodiment] The present invention is a method for performing friction surfacing on the surface of a metal plate. The material for friction surfacing is made of aluminum or aluminum alloy, titanium or titanium alloy, etc. Among the materials to be subjected to friction surfacing, appropriate selection is made. In contrast to the materials to be subjected to friction surfacing, For metal plates, Shao plate, Ming alloy plate, steel plate, stainless steel plate, copper plate, etc. can be used as appropriate. And the sheet material is appropriately selected from metal plates. It is a good property of industrial materials, but when it meets the requirements of the application, 'for example, non-recorded steel plate = anti-two', the characteristics of the Ming or Ming alloy can be given to the original or surname that is unprecedented The age is so 'looking at the characteristics that Shao or Shao alloy does not have, you can add the good properties that Shao or Shao alloy does not have., = As stated above' Relative to | g core alloy, titanium琏 Select the friction overlay welding of the gold alloy to be laminated. 施 Exercise or inscription on the surface of this metal plate = Do not perform overlay welding on the surface of the plate first. The operation of male and F ^ friction overlay welding is as follows ^ friction male implementation, and its Moben Mao knows to use hollow rods as friction overlay welding rods. The so-called rod 316917 200539975 2 'means round rod or square rod .Hollow inside of round or square rod ： = 2 shape, round rod is cylindrical, square rod is the same = shape = column. The shape of the hollow part of the round rod is made into a square shape. It may be inconvenient but not appropriate considering the viewpoint of convenience. .Same, though-the hollow part of a square rod can be made into a cylinder. 1 is not appropriate. For the shape of a cylindrical part in a round rod, what size should be used for the diameter of the circle, considering the friction overlay welding to be performed? The extent of the width is appropriately determined. The meat = what size is used, and the thickness of the desired extent can be considered in consideration of the thickness etc. The cognition of Shi Beiben Yuming et al. 'The diameter of the hollow part of the round rod is too small ... Instead, no good results can be obtained.

It is 1 U outside the diameter of the round bar. If it is below this size, the above effect cannot be obtained. Above 1/2, the above effect can be expected. The upper limit, as long as the hollow heap. The welding rod can maintain a range of strength capable of resisting surfacing. For an outer diameter of 4/5 privacy, it is very likely. ^ The methods for manufacturing a hollow rod-shaped friction surfacing rod include a method using a scale mold forming method, which is rolled into a circular tube, and then the ends are welded, and a method of hollowing out a solid rod is a generally known method. / Under-friction surfacing, the hollow rod-like metal to be surfacing in the metal plate also turns the member into contact with the metal plate, and friction occurs due to the rotation of the rotating member: the same day, so that the metal to be surfacing becomes molten, Spread ¥ on the metal plate again. The rotation action can be used as long as it has a specific rotation operation device. A rotating member made of metal used for slaves is fixed to the rotating shaft. The rotating shaft 316917 '200539975 is fixed to the rotor and can rotate at high speed due to the excitation of the stator. The rotating member can be used while being pushed down during use. The area to be joined can be adjusted by changing the size of the rotating member. If the diameter of the rotating member is large, a large joint area can be obtained. Therefore, the size of the rotating member can be appropriately determined in consideration of the area to be joined and the like.疋. When friction overlay welding of the sheet is to be carried out, the rotating member is brought into contact with the surface of the sheet, the rotating member is rotated at a required speed, and the frictional heat generated at this time is used for execution. The heat generated during the friction is calculated by the product of the friction coefficient of the sheet and the screw, the rotation speed, and the pressure when the rotating member is pressed against the sheet. The speed of rotating members is generally recommended to the extent of _〇rPm

Around. The pressure of pressing the rotating member on the sheet is 0.5 to 5 kg / mm2 Cheng Lu, which is very large. X is used for surfacing welding, and heating is effective. In this case, it is effective to preheat the hollow 2 metal. Heating temperature 'is added at a temperature below the melting point, 1 is ^ when making 1 Lv or Ming alloy laminates' heating to about 450 to 55 generations; when fr is attached to a metal plate on top of a metal plate, == When pasting a metal plate, it is better to perform friction overlay welding on the surface of the surface of the plate to be pasted. The thickness of the material to be made depends on the thickness of the laminated board to be made. It is also possible to perform friction surfacing after friction surfacing. In this way, the other side will use other metals to give the male biography 3 or more laminated boards. Its 316917 12 '200539975, oral fruit can be passed on composite materials with higher characteristics. The degree of dryness of the plant depends on the intended use. To what extent should the pile be made? The friction pile can be determined as a result. Generally, the metal sheet is used below 10mm or 5mm | thin The lower limit, as long as it can ... Thick also. The ground L σ can be. Even if the lmjn degree of thick production ', mouth. Deduct this thickness, review why the thickness of the thick product before rolling is t 侉, and then decide how much the friction pile should do ^ why the thickness. However, the advantages of such friction surfacing ^ &Jun; Jun Yuyu want to cut off the start of surfacing and final surfacing welding to a specific thickness. This step 'may be due to friction surfacing. == ,,: This step is not necessary. At this time, the piles to be treated should be appropriately determined. Next, the metal laminate is lightly heated. The thickness is about 1 mm, and it can be made even if it is about 0.5 mm. If the core part and the end part, cut and add, set it; two cut =: ㈣ can be made of metal laminates of the desired thickness. The thickness is 1 mm or less, and it can be produced even if it is about 0.5 mm according to the purpose of use. In the center of the build-up portion of the metal build-up plate where the build-up portion and the substrate portion show a fine structure, it can be seen that due to the difference in the thickness of the build-up layer before rolling, the share of the thickness of the metal build-up plate The thickness of the surfacing portion is different, but it is recognized that the ratio of the thickness of the surfacing layer to the base material before and after rolling is approximately the same. Furthermore, it was confirmed that the joining surfaces of the laminated metal plates were all in close contact with the structure, and no disorder was observed, which was a good joining method. Metal laminate 316917 13 * 200539975 Result of 4 tensile strength test, value of metal laminate, plastic deformation

The results of Li and 2 margin ratios are both good, and are very satisfactory results. From this, it is known that the metal laminated board prepared by the present invention can be added with an inherent second, that is, different i characteristics can be assigned to the surface and the back of the metal laminated board, respectively. In addition, the thickness of the metal plate that becomes the front surface and the metal plate that becomes the back surface can be appropriately adjusted. For example, when comparing the bonding strength of the aluminum laminated plate manufactured in this way, the laminated θ plate made of aluminum and aluminum alloy with the bonding strength of metal laminated plates made by other methods, the former has very strong strength, and There is no peeling of the build-up layer and the base part after pressing and = after pressing, and it has no corrosion properties. In addition, there are no defects such as cracks or crevices on both sides. The aluminum and aluminum-gold laminates of the present invention are superior to the inscriptions and alloy alloy laminates produced by other manufacturing methods previously known for a variety of industrial applications. The examples are more specific to explain the content of the present invention. . However, the present invention is not limited to the following embodiments. (Example 1) A commercially available 5052 tube (diameter: 27 mm, hollow inner diameter: 1 gmm) was cut into a length of 112 mm and used as a surfacing metal for a hollow rod. For the base material, a 5052 Ming alloy plate (H34, thickness 5mm) is machined to a width of 50mm and a length of 150mm. Use NC to control fully automatic friction crimping machine. The specifications are N = 2500rpm, P = 30MPa, and f = 13mm / s, and friction surfacing is performed. ’The preheating step is performed after the tube comes into contact with the plate substrate, at the friction start position 316917 14 • 200539975 for 3 seconds, at 500 ° C. Then, a machine feed operation with a base material fixed is applied to perform overlay welding. As a comparative example, a commercially available 5052 aluminum solid rod (20 mm in diameter) was cut into a length of 108 mm. For the base material, a 5052 aluminum alloy plate (H34, • plate thickness 5mm) is machined to a width of 50mm and a length of 150mm. -Friction surfacing using NC-controlled fully automatic friction crimping machine. The preheating step is performed after the round bar is in contact with the plate substrate, and the preheating is performed at a temperature of 500 ° C for 3 seconds at the beginning of the friction. Then, the base is fixed, and a machine feed operation is performed to perform overlay welding. The operation at this time is N = 2500rpm, P = 30MPa, and f = 13mm / s. In terms of surface efficiency, the tube of the present invention was 55%, and the solid rod in the comparative example was 25%. In terms of width, the pipe of the present invention is 28 mm, and the solid bar of the comparative example is 20 mm. In terms of length, the pipe of the present invention is 111 mm, and the pipe of the solid bar of the comparative example is 108 mm. In terms of thickness, the pipe of the present invention is 2 mm, and the pipe of the comparative example is 1 mm. The results are shown in Fig. 1. As can be seen from the figure, the welding state of the tube using the present invention is wide and uniform. (Example 2) The base material is a 5052 I Lu alloy plate (H34, plate thickness 5mm) with a width of 50mm and a length of 150mm; the surfacing metal is a 2017 aluminum alloy hollow cylinder (cylinder diameter 20mm, hollow inner diameter 7mm). Machined to a length of 100mm. The mechanical properties of each material 15 316917: 200539975 are shown in Table 1 below. The xi layer friction surfacing welding system uses a numerically controlled fully self-sustaining friction crimping machine. Heap = iW pieces are the conditions in Table 2 below. The surfacing material has a tendency to deviate and the direction of the surfacing metal and the direction of the surfacing are opposite (Retreating Side: hereinafter referred to as RS °) and the opposite side is the Advancing side: also referred to as AS. For this reason, in the second layer of the multi-layer surfacing, the center of the surfacing metal is subjected to surfacing for RS and AS with phases of 5, 10, and 15 planes (hereinafter, the phase of ^ is 15mm, and G = RS15 mark display). Moreover, in order to stabilize the surfacing state, after the surfacing layer is temporarily welded, a second η is temporarily passed before the second layer is surfacing. After surfacing welding, hot rolling was performed to form a laminated board with a thickness of 1 mm. [Table 1] " 2〇71 Aluminum hollow cylinder
