特長が生かされないという問題が残されている。(Prior art) A clinch nut is driven from above a metal panel material set on a lower die using a special tool, and the metal panel material is punched and caulked at the same time, and the clinch nut is driven into the metal panel material and fixed. Panels with clinch nuts, which require simple driving equipment, have been used in recent years in place of weld nuts, which require large-scale equipment such as welding equipment and have a poor finish. (For example, Japanese Patent Publication No. 49-39101, British Patent No. 938490)
(Problem to be Solved by the Invention) However, as shown in Figure 7, the clinch nut used in the panel with clinch nuts described in Japanese Patent Publication No. 49-39101 has screw holes 4' in the center. Flange parts 3', 3' are stretched on the upper end of one opposite side of a square plate-shaped nut main body 1' provided on the top of the nut main body 1'. Since the lower part of the nut 1' is crimped outward, the crimping load on the metal panel material is large, and the crimping part of the lower die is constantly crimping the corner 5' of the nut main body 1'. Since the caulked part is easily damaged and the direction in which the flanges 3' and 3' extend is limited, a special tool placed above the metal panel material set on the lower mold is designed to be directional. There is also the inconvenience that it cannot be used unless the nut body 1' is fed, and furthermore, since the nut body 1' is square, it is difficult to mass-produce by cutting the wire rod and heading like a normal nut, making it expensive. is left behind.
On the other hand, in the panel with a clinch nut described in British Patent No. 938490, a nut body with a flange stretched over the upper end of a tapered short leg tube is driven into the panel material, and the taper of the flange and the short leg tube is tightened. A nut body with a hole edge of the panel material sandwiched between the part formed by scraping off the entire circumference of the part, and a flange part stretched over the top end of a short leg cylinder with tapered ribs arranged on the outer periphery. The edge of the hole in the panel material is sandwiched between the flange and the portion where the tapered rib is crushed by driving into the panel material. Since it is only attached, there is little hope of preventing rotation.Moreover, in the former case, the entire circumference of the tapered part of the short leg cylinder is scraped off, resulting in severe wear and tear on the lower die, and in the latter case, there is also a concave part corresponding to the tapered rib. Since a lower mold is used, press pressure is constantly applied to this recessed part, causing severe wear and tear on this part.In any case, the problem remains that the advantage of the clinch nut, which is simple driving equipment, is not utilized.

A lower mold for driving a clinch nut, which has a narrow annular groove formed on an inclined wall surface on the inside and a vertical wall surface on the outside, and a narrow annular embankment is formed between the annular groove and the circular hole. A metal panel material is set on the cylindrical vertical short leg, and a flange is stretched around the upper edge of the vertical short leg, and a guide part is attached to the outer circumferential surface of the short leg, which is mainly a nut with a screw hole in the center. A clinch nut having a plurality of uniformly arranged ridges with a chevron-shaped cross section whose upper end reaches the lower surface of the flange while remaining at the tip is driven into the circular hole of the lower mold from above the metal panel material to form the short leg part. A punched hole is formed by shearing the metal panel material between the guide part of the lower mold and the hole edge of the circular hole of the lower mold, and the ridge part is cut into the metal panel material by the annular embankment of the lower mold. The lower part of each ridge is pressed into the annular groove of the lower mold together with the inclined edge formed at the edge of the punched hole of the metal panel material, and the inclined wall surface following the annular groove is used to crush each ridge. It is characterized in that the ridge is deformed outward under restraint by the vertical wall surface, and the deformed portion of the ridge is rolled up and caulked around the inclined edge.

から、構造が簡単で安価に提供できる。 1 and 2 are a partially cutaway front view and a bottom view showing an example of a clinch nut used in the present invention, in which 1 is a nut main body, and the nut main body 1 is a cylindrical vertical A flange 3 is stretched around the upper edge of the short leg 2, and a screw hole 4 is provided in the center. A plurality of ridges 5 having a chevron-shaped cross section are arranged uniformly at equal intervals, and each ridge 5 has its lower end located slightly above the leg end of the short leg 2. A guide portion 6 is formed at the end, and the top of the ridge portion 5 having a chevron-shaped cross section forms a flange portion 3.
It is located on the inside of the brim end. On the other hand, FIGS. 3 and 4 are a partially cutaway front view and a plan view showing an example of a lower mold for driving a clinch nut used in the present invention, and 7 in the figure shows the short leg portion of the clinch nut. A circular hole 8 having an inner diameter into which a hole 8 can be inserted.
A lower mold body is provided with an annular groove 10 on the upper surface of the lower mold main body 7, preferably with a narrow annular embankment 9 slightly lower than the upper surface of the lower mold main body 7 remaining at the edge of the circular hole 8. This annular groove 10 has an inclined wall surface 11 on its inner side, that is, the wall surface that continues to the annular embankment 9.
At the same time, the wall surface that continues to the upper surface of the outer lower mold body 7 is a vertical wall surface 12 that continues to the narrow bottom surface 13. The clinch nut is located inside the flange end of the flange 3 of the clinch nut set in a special tool. Note that the vertical wall surface 12 may be slightly inclined to facilitate removal after driving. Therefore, in order to manufacture a panel with a clinch nut using such a clinch nut and a lower die for driving the clinch nut, first, the clinch nut is set in a special tool for driving (not shown) so that the flange 3 is on the upper side. If the metal panel material 1, which is the member to be mounted, is set on the upper surface of the lower die main body 7 of the lower die for driving a clinch nut installed below the special tool, and the special tool is operated, the nut main body 1 is driven. Since there is a circular hole 8 below the cylindrical short leg 2 into which the short leg 2 is inserted, the circumferential edge of the leg end of the short leg 2 and the hole edge of the circular hole 8 provided in the lower mold body 7 are provided. The metal panel material (A) is sheared and punched holes (B) are punched out between the short legs (2), and a chevron-shaped cross section is uniformly arranged on the outer peripheral surface of the short leg (2) so that the upper end reaches the lower surface of the flange (3). The plurality of ridges 5 easily bite into the metal panel material A and deform the hole edge of the punched hole B downward, but at this time, the lower mold body 7 is An annular groove 1 is formed by leaving an annular embankment 9 slightly lower than the upper surface on the edge of the circular hole 8.
0 is provided, and since the portion of the annular groove 10 that continues to the annular embankment 9 is formed on the inclined wall surface 11, the hole edge portion of the punched hole B of the metal panel material A is formed on the vertical wall surface 12. At the same time, the lower part of the ridge part 5 bites into the annular groove 10 along with a part of the inclined edge part C, so that the lower mold This is because the deformed portion 5a of the ridge portion 5 wraps around the inclined edge portion C of the metal panel material A to form the caulked portion D. , the clinch nut is firmly attached and integrated with the metal panel material A with the lower surface of the upper flange 3 in contact with the metal panel material A, and the top of the ridge portion 5 is in contact with the metal panel material A. By being located inside the flange end of the flange portion 3, the flange portion 3 regulates the amount of deformation of the metal panel material A, and prevents the portions other than the inclined edge portion C from being deformed. The clinch nut attached to the metal panel material A in this manner has the lower portions of the plurality of ridges 5 disposed on the outer peripheral surface of the cylindrical short leg portions 2 biting into the metal panel material A. Rotation of the clinch nut is prevented, and the short leg part 2 inserted into the punched hole is removed by the non-planar caulked part D formed by the ridge part 5 wrapping around a part of the metal panel material A. The clinch nut does not come out, and the clinch nut is extremely firmly attached to and integrated with the metal panel material. Furthermore, since the flange portion 3 covers the entire periphery of the punched hole, there are various advantages such as a good sealing effect and a good finish. Furthermore, the nut main body 1 has a flange 3 stretched around the upper edge of the cylindrical short leg 2, and the ridges 5 are arranged uniformly on the outer peripheral surface of the short leg 2 in the same direction. Since there is no clinch nut, it is much easier to feed the special tool and install the lower mold compared to the conventional square clinch nut, and the annular embankment 9 of the lower mold main body 7
Even if the ridge 5 of the nut main body 1 is set in any part of the nut, it can be driven in, and since only the ridge 5 needs to be crushed, the caulking load can be low, and the nut can be used for a long time. In addition, a clinch nut can be easily obtained by cutting the wire rod, forging it with a nut former, and then forming the threaded hole 4 with a tapping machine.Therefore, there is an advantage that mass production can be performed at low cost by changing the attachment method of the nut main body 1. The lower die for driving clinch nuts can be provided with a circular hole 8 in the lower die main body 7 and an annular groove 10 on the upper surface to form an annular embankment 9, so that the structure is simple and can be provided at low cost.
