본 발명은 콘크리트 구조물이나 내화물 등의 구조물을 성형할 때 이들 구조물에 첨가하여 보강재로 사용하는 강섬유(Steel Fiber)에 관한 것이다.The present invention relates to a steel fiber which is used as a reinforcing material by adding to a concrete structure or a refractory when the structure is formed.

더욱 상세하게는, 박판 절단법에 의해 제조되는 강섬유를 저비용으로 대량 생산할 수 있도록 한 표면적을 넓힌 강섬유의 제조장치에 관한 것이다.More particularly, the present invention relates to an apparatus for manufacturing a steel fiber having a large surface area so that a steel fiber produced by a thin sheet cutting method can be mass-produced at a low cost.

일반적으로 콘크리트 구조물이나 내화물 등의 구조물을 성형할 때는 이들 구조물의 강도와 인성 등을 보강해 주기 위하여 강섬유를 사용한다.Generally, when constructing structures such as concrete structures or refractories, steel fibers are used to reinforce the strength and toughness of these structures.

즉, 강섬유는 콘크리트 구조물을 성형할시 몰탈에 첨가되어 구조물의 인장력과 압축력, 전단력, 충격력 등의 기계적인 성질 및 물리적인 성질을 향상시켜 주게 된다.That is, steel fiber is added to the mortar when the concrete structure is molded, thereby improving the mechanical properties such as tensile force, compressive force, shear force, and impact force of the structure.

이러한 강섬유는 통상 강선 절단법과, 용융공법 및 박판 절단법 등에 의하여 제조된다.Such a steel fiber is usually produced by a steel wire cutting method, a melt method, a thin plate cutting method or the like.

강선 절단법은 금속재의 강선을 일정한 길이로 절단하여 강섬유를 제조하는 것으로, 절단된 것 자체를 그대로 사용하거나 또는 부착력이 뛰어나도록 웨이브를 추가하여 사용한다.The steel wire cutting method is to cut a steel wire of a metal material to a predetermined length to produce a steel fiber. The cut wire itself is used as it is, or a wave is added so that it has excellent adhesion.

이 강선 절단법에 의해 제조된 강섬유는 강도가 우수한 반면, 다른 제조 방법에 비해 제조단가가 비싸다는 단점이 있다.The steel fiber produced by this steel wire cutting method has a disadvantage in that it is excellent in strength, but is expensive compared to other manufacturing methods.

용융공법은 금속을 용융시킨 상태에서 오버 플로우 (Over Flow)를 이용하여 강섬유를 제조하는 것으로, 주형에 따라 강섬유의 크기와 형태가 달라진다.The melt process produces steel fibers using overflow in the molten state, and the size and shape of the steel fibers depend on the mold.

그리고, 박판 절단법은 일정한 폭의 이송통로가 형성된 받침판에 자동 절단기를 설치하고, 상기 이송통로 상에 그 보다 작은 폭의 연강판을 이송시키면서 상기 자동 절단기로 절단하여 강섬유의 성형을 완료하는 방법이다.In the thin plate cutting method, an automatic cutter is provided on a support plate on which a conveyance passage with a constant width is formed, and the steel sheet is cut by the automatic cutter while feeding a smaller width steel sheet on the conveyance passage to complete molding of the steel fiber .

이 방법은 연강판을 받쳐주는 받침판의 형태에 따라 강섬유의 모양과 형태가 달라지며, 다른 방법에 비해 제조원가가 적게 든다는 장점이 있다.This method has the advantage that the shape and form of the steel fiber are different according to the shape of the support plate supporting the soft steel plate, and the manufacturing cost is less than other methods.

본 발명은 박판 절단법을 사용하여 강섬유를 제조하는 장치에 관한 것으로서, 강섬유의 표면적을 넓혀주고, 한꺼번에 다량의 강섬유를 동시에 제조할 수 있도록 하여 저비용으로 대량생산이 가능한 강섬유의 제조장치에 관한 것이다.The present invention relates to an apparatus for manufacturing a steel fiber using a thin sheet cutting method, and more particularly, to an apparatus for manufacturing a steel fiber which can enlarge the surface area of a steel fiber and simultaneously produce a large amount of steel fiber at the same time.

종래의 박판 절단법은 원소재인 박판으로부터 소정의 폭(예컨대, 폭 25mm)으로 샤링(Shearing)하여 낱개 별로 이송공정을 통해 가이드 시킨다음, 소정의 길이(대략 0.5∼1mm)로 커팅하여 강섬유를 제조하였다. 그런데, 이와 같은 제조방법은 원소재의 슬리팅(Slitting) 비용이 고가이고, 언코일러(Uncoiler)의 설치비용이 많이들며, 또 제조된 강섬유의 변형이 없어 표면적이 적기 때문에 콘크리트 및 내화물 복합체와의 밀착성이 떨어지는 결점이 있었다. 따라서, 본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 발명된 것으로서, 박판으로 된 강섬유의 표면적을 넓히도록 변형을 주었고, 저비용으로도 대량생산이 가능한 강섬유의 제조장치를 제공함에 있다.The conventional thin plate cutting method is a method of shearing a thin plate made of a raw material to a predetermined width (e.g., 25 mm in width), guiding the plate through a feeding process, cutting the steel fiber into a predetermined length (about 0.5 to 1 mm) . However, such a manufacturing method is expensive because the slitting cost of the raw material is high, the installation cost of the Uncoiler is high, and the surface area is small because there is no deformation of the manufactured steel fiber. Therefore, There is a drawback that adhesion is poor. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an apparatus for manufacturing a steel fiber which is deformed to widen the surface area of a thin steel fiber and can be mass-produced at low cost.

When the fed material is discharged through the upper and lower dies and discharged, The slitter 2 is mounted on the upper and lower shafts 2a and 2a 'so as to be slidable upward and downward with a knife 2a 1 and 2a 2 and the dies 5 and 5a are provided with bending grooves 7 capable of widening the surface area by deforming the material and inclined surfaces 8 for preventing the cutting blade 6 from being damaged at the time of cutting And is integrally formed.

상기 슬리터(2)는 제3도와 같이 회전하는 상,하측의 샤프트(2a, 2a')에 일정한 간격을 두고 서로 엇갈리는 나이프(2a1)(2a2)를 축설하여 상,하측의 나이프(2a1, 2a2)가 상,하로 엇갈리면서 박판(1)을 절단하게 된다.The slitter 2 is provided with knives 2a 1 and 2a 2 staggered at regular intervals on the upper and lower shafts 2a and 2a ' 1 , 2a 2 ) are cut in the upper and lower directions.

상기 상,하판의 다이(5, 5a)는 제4도와 같이 하측 다이(5a)의 소재가 배출되는 후방부에 소정의 길이만큼 다수개의 물결모양의 굴곡홈(70)이 일체로 형성되고, 일측에는 커팅시 커팅날(6)을 보호하기 위한 경사면(8)이 형성된다.The upper and lower dies 5 and 5a have a plurality of wavy bending grooves 70 integrally formed at a rear portion of the lower die 5a through which the material of the lower die 5a is discharged, An inclined surface 8 for protecting the cutting edge 6 at the time of cutting is formed.

그리고, 커팅날(6)은 제 1도에서와 같이 드럼몸체(9)에 일정한 간격으로 다수 설치되고, 상기 드럼몸체(9)는 풀리(10, 11)를 통하여 구동모터(12)와 벨트(13)로 연결된다.A plurality of cutting blades 6 are installed at regular intervals on the drum body 9 as shown in FIG. 1 and the drum body 9 is fixed to the driving motor 12 and the belt 13).

상기와 같이 구성된 본 발명의 동작 및 작용에 대하여 설명하면 다음과 같다.The operation and operation of the present invention will now be described.

먼저, 본 발명은 박판으로 된 원소재를 직접 언코일링 시켜 이송하면서 다수개의 소재로 절개한 후 표면적이 높도록 압출하여 커팅함으로써 원소재의 슬리팅 비용을 절감할 수 있고, 언코일링의 설치비용을 절감할 수 있으며, 대량 생산이 가능하게 된다.First, according to the present invention, a raw material of a thin plate is directly fed by uncoiling, cut into a plurality of materials, extruded and cut to have a high surface area, thereby reducing the slitting cost of the raw material, The cost can be reduced, and mass production becomes possible.

그리고, 상기 상,하판(5, 5a)의 다이중 하측의 다이(5a)에는 물결모양의 굴곡홈(7)이 다수개 형성되어 있어 이 부분을 통과한 소재가 변형되어 물결모양으로 굴곡된 뒤 배출되며, 배출되는 각 소재를 커팅날(6)이 소정의 길이(예컨대, 0.5 ~ 1mm)로 커팅하여 강섬유 제품(14)을 만들게 된다.A plurality of wavy bending grooves 7 are formed in the die 5a on the lower side of the dies of the upper and lower plates 5 and 5a so that the material passed through the upper and lower plates 5 and 5a is deformed and bent into a wavy shape And the cut material 6 is cut to a predetermined length (for example, 0.5 to 1 mm) to produce a steel fiber product 14.

또한, 커팅시에는 일측에 경사면이 형성되어 있어 커팅에 따른 커팅날(6)의 손상을 예방할 수 있다.In addition, at the time of cutting, an inclined surface is formed at one side, so that damage of the cutting edge 6 due to cutting can be prevented.

위와 같이 장치에 의해 제조된 강섬유 제품(14)은 제5도와 같이 물결모양으로 형성되어 표면적이 넓게 되므로 콘크리트에 혼합시 내화물 복합체와의 밀착성을 높고, 보강효과가 뛰어나므로 내화물복합체의 크랙(Crack)등을 방지할 수 있는 것이다.Since the steel fiber product 14 manufactured by the above apparatus is formed in a wavy shape as shown in FIG. 5, the surface area of the steel fiber product 14 is widened to enhance the adhesion to the refractory composite when mixed with concrete, And the like.
