【0008】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint in which two metal plates are integrally fixed without protruding portions, such as a height adjusting spacer. It is about the method. 2. Description of the Related Art A conventional general joining method of a metal plate, a spacer for adjusting a height, and the like will be described with reference to FIGS. 1 is a sectional view of an extruded shrimp, FIG. 2 is a sectional view of an overhang shrimp, FIG. 3 is a sectional view of a shear crimp, FIG. 4 is a perspective view of an example of a spacer, and FIG. FIG. In order to avoid the head height of bolts and nuts at other joints at the joints of the building construction, a spacer or the like for adjusting the height is often laid at the joints. In such a case, if the spacer is made of a thick plate, if there is no material of the appropriate thickness, the upper and lower surfaces of the spacer must be machined, or the mounting holes are inexpensive because of the thick plate. In the case of a thick plate that cannot be pressed by a simple press process or that does not have a commercially available surface-treated steel plate, the surface treatment such as plating must be performed after the process, so that the cost is high. For this reason, two commercially available surface-treated steel sheets are machined into mounting holes, and they are joined. However, due to the nature of a product called a spacer, it is necessary to join without protruding portions from the upper and lower surfaces of the metal plate. However, in the extrusion shampoo as shown in FIG.
As shown in (A), a pin portion 3 is extruded in advance on the upper plate 1 by press working, and a hole for inserting the pin portion 3 of the upper plate 1 is formed in the lower plate 2 in advance. And then, (B)
As shown by, the pin portion 3 of the upper plate 1 is inserted into the hole of the lower plate 2, and the pin head is crimped and joined. In this method, processing into upper and lower plates, caulking and 3 to 4 steps are required. Further, the caulking positional relationship between the pin portion 3 of the upper plate 1 and the hole of the lower plate 2 must be accurately processed. In addition, since the pin head protrudes from the lower plate 2, it cannot be used as it is. In the case of overhanging as shown in FIG. 2, since the upper plate 4 and the lower plate 5 are simultaneously pressed and the cylindrical drawing 6 is performed in one process, the caulking positional relationship between the upper plate 4 and the lower plate 5 is accurately determined. Although it is not necessary, this method can be applied only to thin plates.
Moreover, since the cylindrical aperture 6 projects from the lower plate 5, it cannot be used as it is. In addition, in the shear caulking as shown in FIG. 3, since the upper plate 7 and the lower plate 8 are simultaneously cut and caulked in one step by pressing, it is necessary to accurately set the caulking positional relationship between the upper plate 7 and the lower plate 8. However, this method is also applicable only to thin plates. Moreover, since the cutting bottom 9 protrudes from the lower plate 8, it cannot be used as it is. Therefore, in practice, the following means is used as a method of manufacturing a spacer. The example of the spacer 10 shown in FIG.
3 is obtained by welding the upper plate 11 and the lower plate 12, which are previously vacated, in the side surface direction where the protrusion may come out. In this case, when the welded portion 14 comes out from the upper and lower surfaces of the spacer, sanding must be performed.
Has the disadvantage that the surface treatment is lost, so that a treatment such as painting must be performed. The example of the spacer 15 shown in FIG. 5 is the upper plate 1 in which the mounting holes 18 are previously formed.
6 and the lower plate 17, the upper plate 16 and the lower plate 17 are provided with a countersunk hole 19, and a countersunk rivet 20 is crimped there. This manufacturing method has disadvantages such as a large number of steps and a high cost. [0003] Therefore, the present invention is to accurately determine the positional relationship between the two plates, without performing a welding operation in which the number of processing steps is small and the surface treatment is lost. The present invention relates to a joining structure and a joining method for integrally joining two metal plates without projecting a projection portion. According to the present invention, in order to solve the above-mentioned problems, a hole is formed in only the lower plate by press working, and the fracture surface of the lower hole of the lower plate is swaged downward. Insert the die into the die projection, place the upper plate on top of it, and forge with a caulking die with a punch shape approximately the same as the pilot hole to form a caulking pin on the lower plate and at the same time The pin is coined in the pilot hole. Hereinafter, the present invention will be described in detail based on illustrated embodiments. 6 (D) to 6 (F) are cross-sectional views of the processing steps of the joining structure and the joining method to which the present invention is applied. FIG. 7 is a detailed sectional view of the joining portion. First, a processing method for joining two metal plates will be described. As shown in FIG. 6D, only the lower plate 22 of the two plates is provided with the prepared hole 23 by press working. Next, the prepared hole 23 of the lower plate 22 is fitted into the protruding portion 24 a of the die 24 with the broken portion 23 b of the prepared hole downward.
Next, as shown in FIG. 6E, the upper plate 21 is placed on the lower plate 22.
Layer. Then, coining is performed by a press machine. FIG. 6F shows a state when the press machine is at the bottom dead center. Note that the stripper 26 and the spring 27 are
The upper plate 21 is taken out from 5 and separated. Referring to FIG. 7, a detailed description will be given of the joining portion. Since the prepared hole 23 of the prepared plate 22 is formed by pressing, the shape of the sheared portion 23a of the prepared hole is smaller than the shape of the broken portion 23b of the prepared hole. The material of the upper plate 21 forged by the coining die punch 25 undergoes plastic flow into the pilot hole 23 and flows into the pilot hole 23. At this time, the shape of the punch 25 is substantially the same as the shape of the shear portion 23a of the hole. Then, at the bottom dead center of the press machine, the swaging pin portion 28 formed by plastic flow is formed.
Since the pin bottom 28a and the pin head 28b are strongly pressed by the coining die punch 25 and the die projection 24a, the pin portion 28 whose periphery is constrained and does not escape is laterally plastically deformed. And is firmly and elastically connected to the pilot hole 23 like an interference fit. Furthermore, since the shape of the shear portion 23a of the pilot hole 23 is smaller than the shape of the break portion 23b of the hole, the upper plate 21 and the lower plate 22 are firmly connected to each other in the case where the upper plate 21 and the lower plate 22 are separated from each other in the vertical direction. it can. By using the metal plate bonding structure and the bonding method according to the present invention, the surface treatment is not lost, and the metal plate is firmly mounted in the vertical and horizontal directions without protruding portions from the two plates to be bonded. Can be joined. Also, it is only necessary to make a prepared hole only in the lower plate, and there is no need to perform lower processing such as pins on the upper plate, and there is no need to accurately position the joint between the two plates, so the processing process is small and inexpensive Can be. Also, if the shape of the pilot hole is unified, the same coining type can be used for joining processing, and if the pilot hole is made into a square shape or an oval shape, the joint in one place can reduce the force in the rotational direction. Can also resist. [0008]
