본 고안은 무철심 (無鐵心) 브라인드리뱃트(Blind rivet)의 개방에 관한 것이다. 철판의 집합에 사용되는 통상의 브라인드리뱃트는 리뱃트에 못을 끼워서된 것이어서 리뱃트 하나에 못이 하나씩 소모되는 결점이 있으며 리뱃팅 작업이 불편한 결점이 있었던바 이와같은 브라인드리뱃트의 결점을 제거하기 위하여 무철심브라인드리뱃트가 안출된바 있다.The present invention relates to the opening of a blind rivet. The general brindlevet used for the collection of iron plate is a nail that is attached to the rivet, so that each one of the rivets consumes one nail. An ironless brindlebat was created for this purpose.
무철심브라인드리뱃트는 당김막대에 다수개(약 40개정도)의 리뱃트를 끼운후 하나의 리뱃트씩 사용하게 되는 것으로 극히 편리하고 또 철심으로 사용되던 못을 필요로 하지 아니하여 크게 경제적인 잇점이 있었다. 그러나 이와같은 무철심브라인드리뱃트에 있어서의 가장 큰 결점은 당김막대에 의하여 내부에 형성되는 걸림턱이 비교적 약할뿐 아니라 당김막대를 당김에 있어 상당히 큰 힘이 필요하다는데에 있다.The ironless brindlebatt is used for each one after inserting a number of (about 40) battens into a pulling bar. It is extremely convenient and does not require nails used as iron cores. there was. However, the biggest drawback in such an iron-free brindlement is that not only the locking jaw formed by the pull bar is relatively weak, but also a considerable force is required to pull the pull bar.
즉 종래의 무철심브라인드리뱃트는 제 3 도와 제 4 도에 도시된 바와같이 머리(1)와 몸체(2), 뒷부분(3) 그리고 중공부(4)로 형성되어 있는바 뒷부분(3)에는 외향턱(3')을 형성시켜 몸체(2)의 직경(가)보다는 뒷부분(3)의 직경(나)를 크게 형성시켰다.That is, the conventional iron-free brindlebatt is formed of the head (1) and the body (2), the rear portion (3) and the hollow portion (4) as shown in Figs. The jaw 3 'was formed to form a larger diameter (b) of the rear part 3 than the diameter (a) of the body 2.
뒷부분(3)의 직경은 접합할 철판체(5)(5')에 형성시킨 구멍(6)의 직경보다 작아야함은 물론이다. 이와같은 리뱃트를 사용함에 있어서는 제 4 도에 도시된바와 같이 리뱃트에 당김막대(7)을 끼운후 당김막대(7)의 두부(8)쪽을 접할할 철판체(5)(5')의 구멍(6)으로 밀어넣고 당김막대(7)를 당기면 당김막대(7)의 두부(8)가 리뱃트의 몸체(2)를 외방으로 강제팽창시키게 되어 접합체 철판체(5)(5')의 구멍(6)이 리뱃트의 몸체(2)로 가득차게 되며 따라서 몸체(2)보다 큰 직경을 갖는 뒷부분(3)의 외향턱(3')에 의하여 두장의 판체(5)(5')가 분리되지 아니하도록 결합되는 것이다.Of course, the diameter of the rear part 3 should be smaller than the diameter of the hole 6 formed in the iron plate bodies 5 and 5 'to be joined. In the use of such a rebar, as shown in FIG. 4, the rebar is fitted with a pull bar 7 to be attached to the head 8 of the pull bar 7 to be brought into contact with the head 8 side of the pull bar 7. Of the pull rod (7), the head (8) of the pull rod (7) forcibly expands the body (2) of the raft outwards, thereby joining the plate (5) (5 '). The holes 6 are filled with the body 2 of the raft and thus the two plates 5, 5 ′ by the outward jaws 3 ′ of the rear part 3 having a diameter larger than the body 2. Are combined so that they are not separated.
따라서 이러한 종래의 것은 당김막대(7)의 커다란 두부(8)가 좁은구멍인 중공부(4)를 억지로 빠져나오면서 몸체(2)를 외방으로 팽출시켜야 하니 당기는 힘이 상당하여야 하며 또 외향으로 돌출되는 턱(3')의 높이는 겨우 철판체(5)(5')의 구멍(6)의 직경과 몸체(2)의 직경의 차이에 한하는 것이니 그 집합강도가 만족스럽지 못한 결점이 있었던 것이다.Therefore, this conventional one has to expand the body 2 to the outside while forcing the large head 8 of the pull rod 7 to force the hollow portion 4, which is a narrow hole, and the pulling force must be considerable and protrude outward. The height of the jaw 3 'is only limited to the difference between the diameter of the hole 6 of the iron plate body 5, 5' and the diameter of the body 2, so that the aggregate strength is not satisfactory.
이에 본 고안은 종래의 것에 있어서의 위와같은 결점을 제거하여 작은 힘으로도 당김막대(7)를 당길 수 있게 하고 또 철판(5)(5')의 내측에 생기는 걸림턱(9)을 비교적 두득히 형성시키므로서 집합강도를 향상시킬 수 있도록 안출한 것으로 이를 첨부 도면에 의하여 설명하면 다음과 같다.Therefore, the present invention eliminates the above drawbacks in the conventional one so that the pulling bar 7 can be pulled even with a small force, and the locking jaws 9 generated inside the iron plates 5, 5 'are relatively two. It is devised to improve the assembly strength by forming a lot as described in the accompanying drawings as follows.
본 고안은 머리(1)와 몸체(2), 뒷부분(3) 그리고 중공부(4)로 형성된 통상의 것에 있어서 뒷부분(3)의 중공부(4)에 내향으로 돌출턱(10)을 형성시켰다.The present invention forms a projection jaw 10 inwardly in the hollow portion 4 of the rear portion 3 in the conventional one formed of the head 1, the body 2, the rear portion 3 and the hollow portion 4. .
이와같이 구성된 본 고안은 제 2 도에 도시된 바와같이 몸체(2)의 외경을 철판체(5)(5')의 구멍(6)과 거의 같은 정도로 형성시키고 또 중공부(4)의 직경을 당김막대(7)의 두부(8) 직경과 동일하게 형성시킬 수 있게 되었으며 따라서 이제는 당김막대(7)를 당김에 있어 당김막대(7)의 두부(8)가 뒷부분(3)의 돌출턱(10) 부분만을 외방으로 팽출시키는 정도의 힘만으로 당기면 족하게 된 것이다.The present invention configured as described above forms the outer diameter of the body 2 to approximately the same as the hole 6 of the iron plate bodies 5, 5 ', as shown in FIG. 2, and pulls the diameter of the hollow part 4. It is now possible to form the diameter of the head (8) of the rod (7) so that the head (8) of the pull bar (7) is now the protruding jaw (10) of the back (3) in pulling the pull bar (7) If you pull with only enough force to bulge outward part is enough.
따라서 이제는 극히 작은 힘으로도 당김막대(7)를 당길 수 있게 되었던 것이다.Therefore, you can now pull the pull bar (7) with a very small force.
뿐만 아니라 본 고안은 제 2 도에 도시된 바와같이 외방으로 벌어지는 뒷부분(3)은 철체(5')의 내측단(11)에서부터 외향으로 구부러지게 되므로 접합되는 2매의 철판체(5)(5')가 보다 완강히 접합되며 당김막대(7)의 직경을 작게 하고 내향돌출턱(10)을 크게 형성시키면 철판체(5')의 내측단(11) 부분에 형성되는 걸림턱(9)을 보다 두둑히 형성시킬 수 있어 철판체(5)(5')의 접합을 보다 완강히 할 수 있는 효과가 있다.In addition, the present invention, as shown in FIG. 2, the rear portion 3 that is opened outwardly is bent outward from the inner end 11 of the iron body 5 'so that the two steel plates 5 and 5 joined together. ') Is more firmly bonded and the diameter of the pull rod 7 is reduced and the inward projection 10 is formed to be larger, so that the locking step 9 formed at the inner end 11 portion of the steel plate 5' Since it can form thickly, the joining of the iron plate 5 (5 ') can be made more rigid.
뿐만 아니라 제 3 도에 도시된 종래의 리뱃트를 제조함에 있어서는 외향턱(3')을 형성시키기 위한 별도의 공정을 필요로하나 본 고안은 일반적인 리뱃트제조 공정만으로 족하여 생산비를 절감할 수 있는 효과도 기대할 수 있는 것이다.In addition, in the manufacture of the conventional lithium illustrated in FIG. 3, a separate process for forming the outward jaw 3 'is required, but the present invention satisfies only a general lithium manufacturing process, thereby reducing the production cost. The effect can be expected.
