한편, 상기와 같이 제조된 셀프 피어싱 분할리벳은 두 개의 금속판을 서로 결합하는데 사용되는 것으로 상부금속판과 하부금속판 두 개의 금속판을 서로 리벳으로 결합하는 리벳결합방법에 있어서, 상기 리벳 선단부는 선단부가 슬롯에 의해 두 가닥으로 서로 마주보게 갈라져 있는 것으로, 리벳을 상, 하부 금속판사이에 삽입하되, 리벳이 상부금속판을 투과한 후, 하부금속판에서는 중간에 두 가닥으로 갈라진 선단부가 벌어지면서 고정되므로, 리벳 선단부가 상부금속판만 관통하며 하부금속판은 관통하지 못하고 하부금속판 내부에 고정되게 되어, 상, 하부 금속판을 견고하게 결합하게 되는 것이다.Meanwhile, the self-piercing split rivet manufactured as described above is used to join two metal plates to each other. In the riveting method of riveting two metal plates to an upper metal plate and a lower metal plate to each other, the rivet end portion has a slot in a slot. It is divided into two strands facing each other by inserting the rivet between the upper and lower metal plates, but after the rivet penetrates the upper metal plate, the lower metal plate is fixed while opening the two split ends in the middle. Only the upper metal plate penetrates and the lower metal plate does not penetrate and is fixed inside the lower metal plate, thereby firmly coupling the upper and lower metal plates.
따라서 본발명 셀프 피어싱 분할리벳은 리벳 선단부가 상부금속판만 관통하며 하부금속판은 관통하지 않고 하부금속판 내부에 고정되게 되어, 상, 하부 금속판을 더욱 견고하게 결합하게 되는 현저한 효과가 있다.Therefore, the self-piercing split rivet of the present invention has a remarkable effect that the rivet end portion penetrates only the upper metal plate and is fixed to the inside of the lower metal plate without penetrating the lower metal plate, thereby more firmly coupling the upper and lower metal plates.
또한, 본발명은 셀프 피어싱 분할리벳을 단조공정에 의해 제조함으로, 작업속도가 빠르고 제조단가가 저렴하며 셀프 피어싱 분할리벳의 강도가 크고 치수정밀도가 높다는 현저한 효과가 있다.In addition, the present invention is manufactured by the self-piercing split rivet by the forging process, has a remarkable effect that the work speed is fast, the manufacturing cost is low, the strength of the self-piercing split rivet is high and the dimensional accuracy is high.
본발명 셀프 피어싱 분할리벳 체결방법은 상부금속판(510)과 하부금속판(520) 두 개의 금속판을 서로 리벳(100)으로 결합하는 것이다. 상기 셀프 피어싱 분할리벳(100)은 몸통부(120) 내부 하부에 홈(121)이 형성되고, 또한 상기 내부에 홈(121)이 형성되는 몸통부(120) 하부 선단부(122)는 슬롯(123)이 두 군데가 서로 마주보고 형성되어 있다.Self-piercing split rivet fastening method of the present invention is to combine the two metal plates of the upper metal plate 510 and the lower metal plate 520 with each other with a rivet 100. The self-piercing split rivet 100 has a groove 121 formed in the lower portion of the body portion 120, and a lower end portion 122 of the lower portion 122 of the body portion 120 having the groove 121 formed therein is a slot 123. These two places face each other.
그리고 상기 리벳 선단부(122)는 슬롯(123)에 의해 두 가닥으로 서로 마주보게 갈라져 있는 것으로, 리벳(100)을 상, 하부 금속판(510, 520)사이에 삽입하되, 리벳(100)이 상부금속판(510)을 투과한 후, 하부금속판(520)에서는 중간에 두 가닥으로 갈라진 선단부(122)가 벌어지면서 고정된다. 그리고 리벳 선단부(122)가 상부금속판(510)만 관통하며 하부금속판(520)은 관통하지 않고 하부금속판(520) 내부에 고정되게 되어, 상, 하부 금속판(510,520)을 견고하게 결합하는 것이다.And the rivet tip 122 is divided into two strands facing each other by the slot 123, inserting the rivet 100 between the upper, lower metal plates (510, 520), the rivet 100 is the upper metal plate After passing through the 510, the lower metal plate 520 is fixed while the leading end portion 122 divided into two strands in the middle. The rivet tip 122 penetrates only the upper metal plate 510 and the lower metal plate 520 is fixed to the inside of the lower metal plate 520 without penetrating, thereby firmly coupling the upper and lower metal plates 510 and 520.
그리고 본발명은 엔빌에 탄성체를 설치하여 체결효율을 높일 수 있는 것으로, 상기 하부금속판(520) 하부에 설치되는 엔빌(600) 상면 내부에 우레탄판과 같은 복원력이 뛰어난 탄성체(610)를 설치한다. 상기 우레탄판을 설치하는 방법은 엔빌에 상면 내부에 탄성체 삽입홈을 형성하고, 상기 탄성체 삽입홈에 탄성체인 우레탄판을 삽입한다. In addition, the present invention is to install an elastic body in the anvil to increase the fastening efficiency, install an elastic body 610 with excellent restoring force such as urethane plate inside the upper surface of the anvil 600 is installed in the lower metal plate 520. In the method of installing the urethane plate, an elastic insert groove is formed inside the upper surface of the anvil, and the urethane plate which is an elastic body is inserted into the elastic insert groove.
그리고 상기 탄성체(610)와 하부금속판(520) 사이에는 가이드(640)를 설치하여, 리벳체결초기에는 상기 탄성체(610)가 팽창되어 길이가 늘어나서 엔빌(600)의 홈부(630)의 깊이가 상대적으로 깊게 되고, 리벳팅이 진행함에 따라 상기 탄성체(610)가 압착되어 길이가 줄어듬으로써, 상기 엔빌(600)은 홈부(630)의 깊이가 상대적으로 얕아지게 되는 것이다.In addition, a guide 640 is installed between the elastic body 610 and the lower metal plate 520, and the length of the groove 630 of the anvil 600 is relatively increased by expanding the elastic body 610 at the beginning of the rivet fastening. The depth of the groove 600 is relatively shallow because the elastic body 610 is compressed and the length is reduced as the riveting progresses.
곧 탄성체는 리벳이 초기에 삽입되는 과정에서 좀더 깊이 들어가도록 버티는 역할을 하는 것으로 엔빌은 ‘깊은 엔빌’이 된다. 그리고 압착이 진행되어 압력이 증가되면 엔빌의 탄성체가 눌러지게 되고, 탄성체가 눌러지면 ‘얕은 엔빌’이 되어 리벳 끝단 성형을 향상 시킨다.In other words, the elastic body holds the rivet deeper in the initial insertion process, and the anvil becomes a 'deep anvil'. When the pressure increases as the compression progresses, the elastic body of the anvil is pressed, and when the elastic body is pressed, it becomes a 'shallow anvil' to improve the rivet end forming.
그러므로 탄성체를 엔빌에 설치함으로써 하나의 엔빌인데도 ‘깊은 엔빌’과 ‘얕은 엔빌’2가지 종류의 엔빌을 동시에 쓰는 효과가 있다. 곧, 깊은 엔빌은 리벳을 충분히 삽입시키는 기능을 하며, 얕은 엔빌은 분할리벳의 리벳끝단을 벌리도록 압착하여 상하부 금속판의 밀착을 향상시키게 된다. 한편, 탄성체는 우레탄과 같은 탄성을 가진 합성수지를 사용한다. Therefore, by installing the elastic body in the anvil, it is effective to use two types of anvils, 'deep anvil' and 'shallow anvil' at the same time. In other words, the deep anvil serves to fully insert the rivet, and the shallow anvil is compressed to open the rivet end of the split rivet to improve the adhesion of the upper and lower metal plates. On the other hand, the elastic body uses a synthetic resin having elasticity, such as urethane.
한편, 조선소에서 사용되는 닥트는 닥트끼리 상호 체결하기 전에 아연도강판인 닥트에 두께가 두꺼운 플랜지를 결합하고 플랜지끼지 볼트너트를 사용하여 결합하게 되는데, 상기 플랜지에만 구멍을 뚫고, 아연도강판은 구멍을 뚫지 않은 상태에서 셀프 피어싱 분할리벳을 체결하게 된다.On the other hand, the duct used in the shipyard is combined with a thick flange to the duct of the galvanized steel before fastening the duct between each other and using a flange clamp bolt nut, the only hole in the flange, the galvanized steel is a hole Self-piercing split rivets are tightened without drilling.
곧, 상기 셀프 피어싱 분할리벳으로 플랜지와 닥트를 체결하는 방법 역시 상기 기재된 바와 같이 리벳 선단부(122)가 상부금속판(510)인 플랜지만 관통하며 하부금속판(520)인 닥트는 관통하지 않고 닥트 내부에 고정되게 되어, 플랜지와 닥트를 견고하게 결합하게 된다.In other words, as described above, the method of fastening the flange and the duct with the self-piercing split rivet also penetrates only the flange of the upper metal plate 510, and the duct of the lower metal plate 520 does not penetrate inside the duct as described above. It is secured to securely join the flange and the duct.
따라서 본발명 셀프 피어싱 분할리벳 체결방법은 체결작업이 간단하고 쉬우며, 또한 본발명 셀프 피어싱 분할리벳 체결방법에 의한 리벳체결부위는 인장력 및 강도가 높으며 내구성이 향상되고 체결효율이 좋은 현저한 효과가 있다.Therefore, the self-piercing split rivet fastening method of the present invention is simple and easy, and the riveting part by the self-piercing split rivet fastening method of the present invention has a remarkable effect of high tensile strength and strength, improved durability and good fastening efficiency. .
