Description

철근 직선화 가공장치Rebar Straightening Machine
본 발명은 철근 직선화 가공장치에 대한 것으로서, 더욱 상세하게는 철근의 직선화 과정에서 철근이 외부로 빠져나가는 것을 방지할 수 있는 철근 직선화 가공장치에 대한 것이다.The present invention relates to a rebar straightening processing apparatus, and more particularly, to a rebar straightening processing apparatus that can prevent the reinforcing bar to the outside during the straightening process of the rebar.
철근은 운반 문제로 최대 18 m, 주로 12 m 이하 길이의 정 치수로 사용된다. 철근 가공공장 또는 건설 현장으로 운반된 정 치수 철근은 배근도에 맞춰 필요한 길이로 절단되고, 이 과정에서 자투리 철근이 필연적으로 발생한다. 자투리 철근의 축소를 위해, 철근 배근 상세도 작성, 철근 가공 최적화 등의 다양한 노력이 시도되고 있다.Reinforcing bars are used for transport problems and are used as regular dimensions up to 18 m, mainly up to 12 m long. Regular reinforcing bars transported to the rebar processing plant or construction site are cut to the required length according to the degree of reinforcement, and in this process, stiff bars are inevitably generated. Various efforts have been made to reduce reinforcing bar reinforcement, such as rebar reinforcement detail drawing and rebar processing optimization.
코일철근(reinforcing bar in coils)은 코일형태로 생산되고 철근 가공공장에서 직선으로 펴서 사용된다. 코일철근은 자투리 철근의 손실이 거의 없기 때문에 철근 재료비가 절감되며, 공장 가공에서 철근 인입을 위한 운반이 획기적으로 줄기 때문에 생산성이 향상된다. 최근 철근의 공장 가공 비율이 높아지고, 재료비와 인건비 상승으로 코일철근에 대한 관심이 증가하고 있다.Reinforcing bar in coils are produced in the form of coils and used straight in a rebar processing plant. Coil reinforcement saves reinforcing material costs because there is little loss of reinforcing bar, and productivity is improved because transportation for reinforcing bar is drastically reduced in factory processing. In recent years, interest in coil rebars has increased due to higher processing rates of rebars and higher material and labor costs.
다만, 코일철근을 사용하기 위해서는 직선화 가공이 반드시 필요하다. 철근은 콘크리트와 일체화를 위해 마디를 가지는데, 직선화 가공에서 이 마디를 가압하므로, 마디의 형태는 철근 가공성에 큰 영향을 미친다. 더불어 가공성 향상을 위한 마디의 형태는 철근과 콘크리트 사이의 부착 성능에도 영향을 주며, 또한 직선화 가공에서 발생되는 마디의 손상 또한 부착 성능에 영향을 주므로 직선화 장치와 공정은 매우 중요한 기술이다.In order to use coil rebar, however, straightening is necessary. Reinforcing bars have nodes for integrating with concrete, and since the bars are pressed in the straightening process, the shape of the bars greatly affects the reinforcement of the steel. In addition, the shape of the node to improve the workability also affects the adhesion performance between the reinforcing bar and concrete, and also the damage of the node generated in the straightening process also affects the adhesion performance, so the straightening device and the process are very important technologies.
이러한 직선화 가공은 구부러진 철근을 복수의 롤러 사이에 삽입하고 이 철근을 회전압박함으로서 직선적으로 펴주도록 구성된다. 이때 철근은 구부러진 상태를 가지고 있기 때문에 롤러 사이에 삽입되는 과정에서 철근이 롤러로부터 이탈되는 문제가 빈번하게 발생되는 문제점이 있게 된다.This straightening process is configured to straighten the curved rebar by inserting it between a plurality of rollers and by pressing the reinforcing bar with rotation. At this time, since the rebar has a bent state, there is a problem that the rebar is frequently removed from the roller in the process of being inserted between the rollers.
본 발명은 상술한 문제점을 해결하기 위하여 창출된 것으로서, 더욱 상세하게는 구부러진 철근이 직선화 과정에서 롤러로부터 이탈되는 것을 방지할 수 있는 철근 직선화 가공장치를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and more specifically, an object of the present invention is to provide a rebar straightening processing apparatus that can prevent the bent reinforcement from being separated from the roller in the straightening process.

이러한 본 발명의 철근 직선화 가공장치(100)를 첨부된 도면을 참조하면서 상세하게 설명한다.The rebar straightening processing apparatus 100 of this invention is demonstrated in detail, referring an accompanying drawing.
먼저, 본 발명의 철근 직선화 가공장치(100)는, 코일형태로 감겨진 철근(S)을 직선적으로 펴주는데 사용되는 것이다. First, the rebar straightening processing apparatus 100 of the present invention is used to straighten the reinforcing bars S wound in a coil form.
이러한 철근 직선화 가공장치(100)에서 굽어진 철근(S)이 작업대의 일측으로부터 공급되면 상기 철근(S)은 철근 가이드 수단(120)에 마련된 통과공간(123)을 지나게 된다. 이후에 하부롤러(151)를 통과하여 상부롤러(141)를 지나면서 철근(S)이 압박되고 또한 하부롤러(151)를 다시 철근(S)이 지나면서 철근(S)에 압박을 확실하게 가함으로서 철근(S)이 직선적으로 펴질 수 있도록 한다.When the rebar S bent in the rebar straightening processing apparatus 100 is supplied from one side of the work table, the rebar S passes through the passage space 123 provided in the rebar guide means 120. After passing through the lower roller 151 and passing through the upper roller 141, the reinforcement (S) is pressed, and the lower roller (151) passes through the reinforcement (S) again and firmly presses the reinforcement (S). As the reinforcing bars (S) can be straightened.
이후에 직선적으로 펴진 철근(S)이 작업대의 타측에 마련된 철근 가이드 수단(120)을 통과하면서 배출되도록 구성된다.Later, the straightened rebar S is configured to be discharged while passing through the rebar guide means 120 provided on the other side of the workbench.
한편, 철근(S)의 회전압박량을 변화시킬 필요가 있는 경우에는 하부롤러(151)의 위치를 변경한다. 즉, 하부롤러(151)와 상부롤러(141) 사이의 간격을 조정함으로서 압박량을 조절할 수 있다. 이러한 하부롤러(151)의 위치조절을 위하여 고정용 너트(1544)를 풀어서 스크류 너트(1542)로부터 이격시키고 이후에 핸들을 돌려서 스크류부재(1541)를 회전시키면, 상기 스크류부재(1541)에 나사결합되어 있는 스크류 너트(1542)가 직선적으로 이동하게 된다. 스크류 너트(1542)가 이동하게 되면 상기 스크류 너트(1542)와 결합된 고정부(1543)도 함께 직선이동하게 되고 상기 고정부(1543)를 감싸는 샤프트(153) 및 하부롤러(151)도 전체적으로 직선적으로 이동하게 된다.On the other hand, when it is necessary to change the rotational compression amount of the reinforcing bars S, the position of the lower roller 151 is changed. That is, the amount of pressing can be adjusted by adjusting the interval between the lower roller 151 and the upper roller 141. In order to adjust the position of the lower roller 151, the fixing nut 1544 is released and spaced apart from the screw nut 1542, and afterwards, by rotating the screw member 1541 by rotating the handle, screwing the screw member 1541 Screw nut 1542 is moved linearly. When the screw nut 1542 is moved, the fixing part 1543 coupled with the screw nut 1542 also moves linearly, and the shaft 153 and the lower roller 151 surrounding the fixing part 1543 are also generally linear. Will be moved to.
하부롤러(151)를 적절한 위치에 배치시킨 후에는, 고정용 너트(1544)를 상기 스크류 너트(1542) 양측에 각각 체결함으로서 상기 스크류 너트(1542)가 직선이동하는 것이 방지된다.After arranging the lower roller 151 in an appropriate position, the screw nut 1542 is prevented from linearly moving by fastening the fixing nut 1544 to both sides of the screw nut 1542 respectively.
이러한 본 발명에 따른 철근 직선화 가공장치는, 다음과 같은 장점을 가진다.Rebar straightening processing apparatus according to the present invention has the following advantages.
먼저, 본 발명에 따른 철근 직선화 가공장치는, 작업대에 철근가이드 수단이 마련되어 있어서 코일형태로 감겨서 구부러진 철근이 직선화되는 과정에서 롤러에서 이탈되는 것을 방지할 수 있다.First, the rebar straightening processing apparatus according to the present invention is provided with a reinforcing bar guide means on the workbench can be prevented from being separated from the roller in the process of straightening the bent reinforcing bar is coiled.
또한 하부롤러에 상기 하부롤러보다 외측으로 돌출된 커버부재를 마련함에 따라서 구부러진 철근이 직선화되는 과정에서 하부롤러의 제2롤러홈에 안착되지 못하고 상측으로 이탈되는 것을 방지할 수 있는 장점이 있다.In addition, by providing a cover member protruding outward from the lower roller in the lower roller, there is an advantage in that the bent rebar is prevented from being separated from the upper side without being seated in the second roller groove of the lower roller.
또한, 하부롤러의 위치를 가변적으로 이동가능하게 하고, 위치이동 및 고정을 간단한 구조로 구현함으로서 회전압박력을 간편하게 조정할 수 있는 장점이 있게 된다.In addition, the position of the lower roller can be moved variably, and by implementing a position movement and fixing in a simple structure there is an advantage that can easily adjust the rotational pressure force.
