In the example shown in Fig. 6, the bottom surface 14a of the peripheral convex portion 14A is disposed perpendicularly to the longitudinal direction of the upper mold.

S -12- 201204285 The level of intersection, however, is not limited to this. As shown in Fig. 5, the thickness of the peripheral convex portion 14A (the length parallel to the longitudinal direction of the upper mold 10A) is formed so as to gradually increase from the peripheral edge portion 12A toward the expansion permitting portion 13A (the center of the action bottom portion 11A). . The peripheral recess 15A is a strip-shaped bottom surface along the peripheral edge portion 12A. The bottom surface may also be inclined upwardly toward the center of the bottom portion 1 1 A, or may be a plane parallel to the bottom surface of the peripheral convex portion 14A. - Mounting method - Next, the mounting procedure of attaching the female button 20A to the sheet 1 using the button mounting upper mold 10A of Fig. 5 will be described. Fig. 7 is a view showing an arrangement state in which the female fastener button 20A is attached to the base of one of the sheets 1 in the upper and lower directions (axial direction), and the upper mold 10A for the button mounting is used from the top to the bottom. The fastener button 20A, the sheet body 1, the mounting member 30', and the lower mold 40 supporting the mounting member 30. The lower mold 40 has thereon a support recess 41 for receiving the base portion 31 of the mounting member 30. The support recess 41 carries the mounting member 30 such that the axis of the shaft portion 32 of the mounting member 30 and the upper mold 10A The axis becomes the same. In the initial stage of installation in Fig. 8, the shaft portion 32 of the attachment member 30 passes through the sheet body 1, and then passes through the opening 24A of the female fastener button 20A to penetrate the engagement recess portion 21A side of the upper female fastener button 20A. Next, as shown in Fig. 9, the upper mold 10A is lowered (sometimes the lower mold 40 is raised), and the front end 32d of the shaft portion 32 of the mounting member 30 is accommodated in the center portion 11A. 13-201204285 central recess 1 3 1 Within a. Thereby, the center calibration of the mounting member 30 is automatically performed. Here, the upper mold 10 is further lowered, and the annular convex portion 132a of the action bottom portion 11 is bitten into the shaft portion 32. From this point on, the bottom portion 11 is applied, and as shown in Fig. 10, the upper portion (bottom surface) 23A' of the bottom portion 23A of the female fastener button 20A is crushed by the shaft portion 32, whereby the female fastener button 20A is fixed to the sheet. On body 1.

The annular recessed portion 133a and the peripheral recessed portion 15A project outward in the radial direction. Further, as shown in Fig. 5, the peripheral convex portion 14A is formed by gradually thinning from the center of the action bottom portion 11A toward the peripheral edge portion 12A, and as shown in Fig. 6, the top portion 14b has an arc shape. . Therefore, the presence of the peripheral convex portion 14A is resistant to the deformation of the shaft portion 32 toward the outer side in the radial direction, and there is almost no shadow #. Further, the shape of the end portion 32a of the shaft portion 32 coincides with the concavo-convex shape of the action bottom portion 11A. Thus, the end portion 32a of the tightened shaft portion 32 is alternately formed in the circumferential direction: a larger portion (edge portion 3 22a ) corresponding to the radially outer side of the annular recess portion 133a; and a peripheral convex portion 14A The smaller portion (not shown) is expanded, and its appearance is a radial shape (flower shape) having six ribs as shown in Fig. 1. As described above, according to the mounting method of the upper mold for button attachment according to the first embodiment, for example, when the sheet 1 is thick, the axis of the mounting member 30 is -14-

The relatively large deformation of the S 201204285 portion 32 on the outer side in the radial direction is concentrated between the peripheral convex portions 14A, and the necessary button mounting force can be secured. Further, when the sheet body 1 is thin, since the deformation of the shaft portion 32 in the radial direction outward is dispersed in the circumferential direction, the force necessary for fastening is small, so that the load on the punching machine is not increased.

Here, the upper mold 10B is further lowered (or the expansion acting surface 131b is lowered along the side wall portion 1 3 2b), and as shown in Fig. 18, the expansion acting surface 131b crushes the front end 32d of the shaft portion 32. Thereby, the shaft portion 32 is expanded outward in the radial direction on the opening 24A on the bottom surface 23A' of the bottom portion 23A of the female fastener button 20A, and continues to be crushed under the portion where the peripheral concave portion 15B receives the outer expansion permitting portion. Thereby, the rib portion 322b is formed in the peripheral recess portion 15B, and the female fastener button 20A is fixed to the sheet body 1. According to the mounting method of the button mounting upper mold of the second embodiment, the method of mounting the -19-201204285, even if the sheet 1 is thick, the shaft portion 32 of the mounting member 30 is concentrated on the expansion permitting portion 13B, and the excess portion is The peripheral recessed portion 15B is expanded to perform relatively large deformation toward the outside in the deformation direction, thereby securing the necessary button attachment force. Further, when the sheet body 1 is thin, since the deformation of the shaft portion 32 in the radial direction outward is dispersed in the circumferential direction, the force necessary for fastening is small, so that the load of the punching machine is not increased. (Other Embodiments) The embodiments of the present invention described in the above description are not intended to limit the scope of the invention. For example, between the peripheral concave portion 15A of the upper mold 10A and the expansion permitting portion 13A shown in Fig. 5, an edge 151 for defining the boundary between the peripheral concave portion 15A and the expansion permitting portion 13A is formed, but is not limited thereto. For example, the strip-shaped bottom surface shown in Fig. 5 may be a sloped shape that gradually slopes upward toward the expansion permitting portion 13A, and the end portion of the strip-shaped bottom surface portion is not formed with the edge 151 and is integrated with the annular recessed portion 133a. And formed in a continuous manner. It is also possible not to have the annular ridge 3 23 a shown in Fig. 1. That is, as shown in FIG. 19, a button having the following configuration, that is, the end portion 32a of the shaft portion 3 2 may be disposed on the button body so as to cover one of the opening 24A (not shown) and the bottom portion 23A. 20 (not shown), and is formed integrally with a plate-shaped base portion 321a that is raised at the center portion and a base portion 321a on the surface of the base portion 321a, and is oriented from the center portion of the base portion 321a toward the outer circumference. A button formed by a radially extending ridge 322a. Rib

The outer end portion of the rib portion 3 22a may be located further inside than the outer circumference of the base portion 321a. The central concave portion 131a, the annular convex portion 13 2a ', and the annular concave portion 133a shown in Fig. 5 may not be provided. That is, as shown in Fig. 20, the expansion permitting portion 13C of the upper mold 10C may be an expansion acting surface 131c for pressing the pressing surface of the front end 3 2d of the shaft portion 32 during fastening; The expansion peripheral surface 132c around the expansion surface 131c is configured. At this time, the expansion acting surface 131c may have a flat surface or a curved surface. The expansion peripheral surface 132c may be a curved surface or an inclined surface that is concavely diffused from the expansion acting surface 131c toward the peripheral edge portion 12C. In the example shown in Fig. 1, the thickness of the edge portion 32 2b of the end portion 32b of the shaft portion 32 is formed to be thinner than the base portion 321b. However, as shown in Fig. 21, the thickness of the edge portion 322c and the base portion 321c of the end portion 32c of the shaft portion 32 may of course be the same. Further, the member 1 and the member 1 〇 1 shown in Fig. 16 may be integrally formed. Further, as shown in Fig. 17, the expansion surface 131b of the upper mold 10B is illustrated on the plane and perpendicular to the plane of the side wall portion 132b, however, it may correspond to the shape of the button to be manufactured. The surface having the reverse U-shaped cross section is as shown above. The present invention, of course, also includes various forms that cannot be clearly illustrated herein, and may be modified to obtain specific conditions without departing from the scope of the gist of the invention in the implementation stage.
