강연성선재 제조용 성형롤러{Forming roller for the manufacture of a rigid and ductile wire}Forming roller for the manufacture of a rigid and ductile wire}

본 발명은 강연성선재 제조용 성형롤러에 관한 것으로, 보다 상세하게는 콘크리트 구조물이나 내화물 등에 보강용으로 첨가되는 강연성선재를 연속적으로 밴딩 및 절단시킬 수 있고, 커팅날의 손상시 이를 용이하게 교체 사용할 수 있는 강연성선재 제조용 성형롤에 관한 것이다.The present invention relates to a forming roller for the production of ductile wire, more specifically can be continuously bending and cutting the ductile wire is added for reinforcement, such as concrete structures or refractory, it is easy to use when replacing the cutting blade The present invention relates to a forming roll for producing a flexible wire rod.

일반적으로 콘크리트 구조물이나 내화물 등의 구조물을 성형할 때는 이들 구조물의 기계, 물리적인 성질을 향상시켜 주기위하여 그 재료인 콘크리트 및 내화물 복합체에 강섬유를 혼합하여 성형한다.In general, when forming structures such as concrete structures or refractory materials, in order to improve the mechanical and physical properties of these structures, they are formed by mixing steel fibers in the concrete and refractory composites thereof.

따라서, 성형이 완료된 구조물은 상기의 강섬유로 인해 인장력과 압축력, 전단력, 충격력, 인성 등의 기계적인 성질 및 물리적인 성질이 향상된다.Therefore, the completed structure is the mechanical properties and physical properties of the tensile strength, compression, shear, impact, toughness, etc. due to the steel fiber is improved.

강섬유로는 통상 금속편이 사용되며, 콘크리트 구조물이나 내화물의 성형시 이들 구조물의 재료에 함께 혼합하여 성형한다.Metal pieces are generally used as steel fibers, and are molded together with materials of these structures when forming concrete structures or refractory materials.

이러한 강섬유를 제조하는 방법으로는 통상 강선 절단법과, 용융공법 및 박판 절단법 등이 있다.As a method for producing such steel fibers, there are usually a steel wire cutting method, a melting method, a thin plate cutting method, and the like.

상기 강선 절단법은 금속재의 강선을 일정한 길이로 절단하여 강섬유를 제조하는 것으로, 절단한 것 자체를 그대로 사용하거나또는 부착력이 뛰어나도록 하기 위하여 웨이브를 추가할 수도 있다.The steel wire cutting method is to produce a steel fiber by cutting a steel wire of a certain length, it is also possible to use the cut itself as it is or to add a wave to make excellent adhesion.

상기 강선 절단법의 의해 제조된 강섬유는 강도가 우수한 반면, 다른 제조 방법에 비해 제조비가 많이 들어간다는 단점이 있다.Steel fiber produced by the wire cutting method has a high strength, but has a disadvantage in that the manufacturing cost is much higher than other manufacturing methods.

상기 용융공법은 금속을 용융시킨 상태에서 오버 플로우(Over Flow)를 이용하여 강섬유를 제조하는 것으로, 주형에 따라 강섬유의 크기와 형태가 달라진다.The melting method is to produce a steel fiber by using an overflow (Over Flow) in a molten metal state, the size and shape of the steel fiber varies depending on the mold.

그리고, 박판 절단법은 일정한 폭의 이송통로가 형성된 받침판에 자동 절단기에 설치하고, 상기 이송통로 상에 그보다 작은 폭의 연강판을 이송시키면서 상기 자동 절단기를 이용하여 절단하므로써 강섬유를 제조하는 방법이다.In addition, the thin plate cutting method is a method of manufacturing steel fibers by installing the automatic cutting machine on a support plate having a constant width conveying path, and cutting using the automatic cutting machine while transferring a mild steel plate having a smaller width on the conveying path.

상기 박판 절단법은 연강판을 받쳐주는 받침판의 형태에 따라 강섬유의 모양과 형태가 달라지며, 다른 방법에 비해 제조원가가 적게 든다는 장점이 있다.The thin plate cutting method has the shape and shape of the steel fiber according to the shape of the support plate supporting the mild steel plate, there is an advantage that the manufacturing cost is lower than other methods.

그러나, 종래의 박판 절단법에 의한 제조방법은 폭이 넓은 박판(원소재)을 일정한 폭(예컨대, 약 25mm 정도의 폭)으로 슬리팅(Slitting)하여 여러개의 소재로 만든 다음, 이들 각각의 소재를 하나씩 낱개 별로 이송시켜 가면서 일정한 길이(대략0.5-1mm 정도)로 절단하여 강섬유를 제조하는 것이였다.However, in the conventional manufacturing method by the thin plate cutting method, the wide plate (the raw material) is slitted to a certain width (for example, about 25 mm width) to make a plurality of materials, and then each of these materials. Was transported one by one while cutting to a certain length (about 0.5-1mm) was to produce a steel fiber.

그런데, 상기와 같은 제조방법은 원소재의 슬리팅(Slitting) 비용이 고가이고, 언코일러(Uncoiler)의 설치 비용이 많이들며, 또한 제조된 강섬유의 변형이 없는 관계로 표면적이 작기 때문에 콘크리트 및 내화물 복합체와의 밀착성이 떨어지는 단점이 있었다.However, the manufacturing method as described above has a high cost of slitting of raw materials, high installation cost of uncoiler, and small surface area due to no deformation of the manufactured steel fibers. There was a disadvantage of poor adhesion with the composite.

상기의 문제점을 해결하기 위해 박판을 이용한 강섬유의 제조장치의 일실시예를 도 6에 도시하였는데, 상기 강섬유 제조장치는 코일링된 박판(101)을 언코일링 하면서 슬리터(Slitter,102)를 통하여 일정한 폭(예컨데, 25mm정도)으로 절단하고, 절단된 복수개의 소재(a)를 롤러(103)로 압착 이송시키면서 가이드부(104)를 통과하여 상, 하판의 다이(105,105a)에 인입시키면, 인입된 소재가 다이를 통하여 배출될 때 드럼몸체(109)의 커팅날(106)로 절단하도록 이루어진다.In order to solve the above problems, an embodiment of a steel fiber manufacturing apparatus using a thin plate is illustrated in FIG. 6, wherein the steel fiber manufacturing apparatus uses a slitter (Slitter, 102) while uncoiling the coiled thin plate 101. After cutting through the guide portion 104 while cutting a plurality of raw materials (a) by pressing the roller 103 to the upper and lower dies 105, 105a When the drawn material is discharged through the die, it is made to cut with the cutting blade 106 of the drum body 109.

여기서, 상기 다이(105,105a)에는 소재(a)를 변형시켜 표면적을 넓힐수 있는 굴곡홈(107)과 컷팅시 커팅날(106)의 손상을 방지하기 위한 경사면(108)을 일체로 형성하며, 성형롤러(109)의 커팅날(106)에 수직여유각 및 날끝경사각을 준 것이다.Here, the dies 105 and 105a are integrally formed with a curved groove 107 that can deform the material a to widen its surface area and an inclined surface 108 to prevent damage to the cutting edge 106 during cutting. The cutting edge 106 of the forming roller 109 is given a vertical margin angle and the blade tip inclination angle.

그러나, 상기 성형롤러(106)는 커팅날(106)이 일체형으로 장착되어 상기 커팅날(106)이 손상되면 상기 성형롤러(106) 전체를 교체해야하므로, 유지비용이 상승되는 문제점이 있었다.However, since the forming roller 106 is integrally mounted with the cutting blade 106 and the cutting blade 106 is damaged, the forming roller 106 needs to be replaced.

또한, 다이(105,105a)를 통과시켜 소재(a)를 변형시켜 표면적이 넓히는 작업이 원활하지 못하며, 상기 커팅날(106)의 마모시 소재(a)의 절단이 제대로 이루어지지 않아 정확한 치수의 제품을 얻을 수 없는 단점이 있다.In addition, it is difficult to widen the surface area by deforming the material (a) by passing through the die (105, 105a), the product of the correct dimensions because the cutting of the material (a) is not properly made when the cutting edge 106 is worn There is a disadvantage that can not be obtained.

본 발명은 상기한 제반 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 댐, 터널, 교량 등 비교적 견고한 구조물에 구축에 사용되는 콘크리트의 강도를 향상시키기 위해 첨가되는 강연성선재를 성형롤러에 의해 표면적을 넓힘과 아울러 상/하부로 웨이브 형상으로 밴딩시켜 절단함으로써 콘크리트 및 내화물 복합체와의 밀착성이 뛰어나고 인성 및 강도 향상시킬 수 있으며, 커팅날의 손상시 이를 용이하게 교체 사용함으로써 성형롤러를 반 영구적으로 사용할 수 있어 유지비용이 절감되며, 감속모터와 성형롤러의 감속비로 강연성선재를 대량생산할 수 있어사용신뢰성이 우수한 강연성선재 제조용 성형롤러를 제공하는데 있다.The present invention was devised to solve the above problems, and an object of the present invention is to add a ductile wire added to the forming roller to improve the strength of concrete used in the construction of relatively rigid structures such as dams, tunnels and bridges. By widening the surface area and cutting it by bending the wave shape in the upper and lower parts, it has excellent adhesion with concrete and refractory composites and can improve toughness and strength.

이는, 상기 커팅날고정부재(30)를 상기 제1/2성형롤러(12b,13b)에 밀착/고정하는 조임볼트(32)와 와셔(33)를 볼트홀(31)로부터 분리시킨 후, 상기 커팅날고정부재(30)와 상기 커팅날(20)을 고정홈(14)에서 분리하여 새로운 커팅날(20)을 교체하여 사용할 수 있는 것이다.This is, after separating the tightening bolt 32 and the washer 33 from the bolt hole 31 to close / fix the cutting blade fixing member 30 to the first and second forming rollers 12b and 13b. The cutting blade fixing member 30 and the cutting blade 20 can be used by replacing the new cutting blade 20 by separating the fixing groove 14.

즉, 종래의 성형롤러는 커팅날이 일체형으로 형성된 것으로, 커팅날이 손상되면 성형롤러 전체를 교환하여 사용했으나, 본 발명의 제1/2성형롤러(12b,13b)는 상기 커팅날(20)을 교환하여 사용함으로써 반 영구적으로 사용할 수 있는 것이다.That is, the conventional forming rollers are formed integrally with the cutting blades, but when the cutting blades are damaged, the entire forming rollers are replaced and used, but the first and second forming rollers 12b and 13b of the present invention are the cutting blades 20. It can be used semi-permanently by exchanging it.

상기 제1/2성형롤러(12b,13b)에 의해 성형된 상기 강연성선재(T)는 표면적이 넓어 콘크리트 및 내화물 복합체와 혼합시 밀착성이 뛰어나고, 또한 웨이브형상으로 밴딩되어 수직하중에 대한 보강효과가 우수하여 구조물의 균열을 방지하게 된다.The ductile wire T formed by the first and second forming rollers 12b and 13b has a large surface area and is excellent in adhesion when mixed with concrete and a refractory composite, and is also bent into a wave shape to reinforce the vertical load. It is excellent to prevent the crack of the structure.

이와 같이, 본 발명의 구체적인 실시예에 관해 상세히 설명하였으나, 본 발명이 속하는 분야에 통상의 지식을 갖는 자라면 본 발명의 범주에서 벗어나지 않는 범위에서 다양한 변형실시가 가능할 것이다.As described above, specific embodiments of the present invention have been described in detail, but those skilled in the art will appreciate that various modifications can be made without departing from the scope of the present invention.

그러므로, 본 발명의 범위는 상술한 실시예에 한정되서는 안되며, 후술하는 특허청구범위 뿐만 아니라, 이 청구범위와 균등한 것들에 의해 정해져야 할 것이다.Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be defined not only by the claims below, but also by those equivalent to the claims.

상술한 바와 같이 본 발명에 의하면, 제1/2성형롤러에 진입되는 강연성선재를 치면에 따라 압착하여 표면적을 넓혀 줌으로써 콘크리트 및내화물 복합체와의 밀착성이 뛰어나고, 웨이브 형상으로 밴딩시켜 절단함으로써, 인성 및 강도 향상시킬 수 있는 장점이 있다.As described above, according to the present invention, the ductile wire rod entering the first and second forming rollers is pressed along the tooth surface to widen the surface area, thereby providing excellent adhesion to the concrete and the refractory composite, and bending by cutting into a wave shape, thereby providing toughness. And there is an advantage to improve the strength.

그리고, 제1/2성형롤러의 치면과 커팅날에 의해 원하는 치수의 강연성선재를 성형할 수 있으며, 장착된 커날이 손상되거나 마모가 심한 경우에는 커팅날고정부재를 분리시켜 새로운 커팅날로 교환해줌으로써 제1/2성형롤러를 반영구적으로 사용할 수 있는 장점이 있다.In addition, the ductile wire of the desired dimension can be formed by the tooth surface and the cutting blade of the 1/2 forming roller.If the mounted kernel is damaged or wears severely, the cutting blade fixing member can be separated and replaced with a new cutting blade. There is an advantage that can be used semi-permanently by the 1/2 molding roller.

또한, 감속모터와 성형롤러의 감속비로 강연성선재를 저비용으로 대량생산할 수 있어 사용신뢰성이 우수한 효과가 있다.In addition, due to the reduction ratio between the reduction motor and the forming roller, the ductile wire can be mass-produced at a low cost, and thus the use reliability is excellent.
