Description

유격조절장치 및 이를 포함하는 철재절단장치{APPARATUS FOR ADJUSTING CLEARANCE AND CUTTING APPARATUS FOR INCLUDONG IN THE SAME}Gap control device and steel cutting device including the same {APPARATUS FOR ADJUSTING CLEARANCE AND CUTTING APPARATUS FOR INCLUDONG IN THE SAME}

본 발명은 유격조절장치에 관한 것으로서, 더욱 상세하게는 철재를 절단하기 위한 철재절단장치에 포함된 유격조절장치 및 이를 포함하는 철재절단장치에 관한 것이다.The present invention relates to a clearance control device, and more particularly, to a clearance control device included in an iron cutting device for cutting iron and an iron cutting device including the same.

철재절단장치는 철재를 절단하는 장치이다. 종래의 철재절단장치의 구조의 일예로 몸체와, 몸체에 회전가능하게 결합된 죠를 포함할 수 있다. 죠에는 절단날이 형성되어 있고, 몸체에서 죠의 절단날과 대응되는 부분에도 절단날이 형성된다. 몸체에 대해 죠를 회전시켜서 이러한 절단날들이 인접하게위치하도록 하여 철재의 특정 부분을 절단한다. 죠는 몸체 내에 배치된 유압실린더에 의해 회전될 수 있다.The steel cutting device is a device for cutting steel. An example of the structure of a conventional steel cutting device may include a body and a jaw rotatably coupled to the body. The cutting blade is formed in the jaw, and the cutting blade is formed in the body corresponding to the cutting blade of the jaw. The jaws are rotated with respect to the body so that these cutting blades are placed adjacent to each other to cut a specific part of the steel. The jaw can be rotated by a hydraulic cylinder disposed in the body.

한편, 죠는 회전축에 의해 몸체에 회전가능하게 결합된다. 죠와 부시 사이에는 복수개의 쉼(shims)들이 배치되어 죠와 몸체 사이의 틈을 최소화한다. 죠가 몸체에 대해 회전되는 과정에서 죠와 부시 사이에서 마찰이 발생되게 된다. 이 경우, 죠와 부시가 접촉되는 면이 마모되는 현상이 나타나게 된다. 이로 인하여 죠가 회전축의 길이 방향으로 움직일 수 있는 축방향의 유격이 더욱 증가되어 절단날들 사이의 간격이 더욱 벌어지게 된다. 이와 같이 죠의 절단날과 몸체의 절단날 사이의 간격이 유지되지 않게 되면, 철재절단장치의 절단성능이 저하된다. 뿐만 아니라, 얇은 철재가 절단날들 사이에 끼여 들어가게 된다. On the other hand, the jaw is rotatably coupled to the body by the rotation axis. Multiple shims are placed between the jaw and the bush to minimize the gap between the jaw and the body. As the jaw rotates about the body, friction occurs between the jaw and the bush. In this case, a phenomenon in which the surface contacting the jaw and the bush is worn out appears. This further increases the axial play through which the jaw can move in the longitudinal direction of the rotary shaft, thereby further increasing the spacing between the cutting edges. As such, when the gap between the cutting blade of the jaw and the cutting blade of the body is not maintained, the cutting performance of the steel cutting device is reduced. In addition, thin steel is sandwiched between the cutting edges.

통상적으로 철재절단장치에서는 죠를 오므리게하는 힘을 벌리는 힘보다 크게 하기 위하여 죠를 회전시키는 유압실린더의 축력이 크게 발휘되는 신장 방향으로 작동할 때 죠가 오므려지게 구성되어 있다. 따라서 철재가 절단날들 사이에 끼이게 될 때는, 큰 힘으로 물려 들어가게 된다. 이때, 죠를 벌리는 힘은 죠를 오므리는 힘보다 상대적으로 약하기 때문에 유압실린더의 힘만으로는 죠를 벌릴 수 없다. 그러므로, 유압 잭이나 햄머등을 이용하여 죠를 벌리고, 이러한 조치로 충분하지 않을 때에는 가스토치로 열을 가하여 절단날 사이에 끼인 대상물을 제거한다. 이 경우, 대상물을 제거하는 과정에서 죠 또는 절단날들을 손상시키게 되고, 제거 작업 시간 동안 절단 작업이 멈추게 되므로 가동 효율이 떨어지게 되는 문제점이 있다. In general, the steel cutting device is configured to retract the jaw when it is operated in the extending direction in which the axial force of the hydraulic cylinder that rotates the jaw is exerted so as to be larger than the opening force to retract the jaw. Therefore, when the steel is caught between the cutting edges, it is forced into a large force. At this time, the jaw opening force is relatively weaker than the closing force of the jaw, so the force of the hydraulic cylinder alone cannot open the jaw. Therefore, the jaws are opened using hydraulic jacks or hammers, and when these measures are not sufficient, heat is applied with a gas to remove the objects caught between the cutting blades. In this case, the jaw or the cutting blades are damaged in the process of removing the object, the cutting operation is stopped during the removal operation time, there is a problem that the operation efficiency is lowered.

한편, 철재절단장치를 장기간 사용하면서 죠와 부시가 접촉되는 면들의 마모가 진전되어 죠와 본체 사이의 틈이 커지게 되면, 쉼을 철재절단장치에 더 추가 조립하여 유격을 최소화 할 수 있다. 그러나, 쉼을 철재절단장치에 추가하기 위해서는 철재절단장치를 분해시켜야만 하기 때문에 많은 시간과 인력이 소요되는 문제점이 있다.On the other hand, when the use of the steel cutting device for a long time and the wear of the surface contacting the jaw and the bush is increased, the gap between the jaw and the main body becomes larger, the shim can be further assembled to the steel cutting device to minimize the play. However, in order to add a shim to the steel cutting device, the steel cutting device has to be dismantled, which requires a lot of time and manpower.

본 발명은 철재절단장치에서 절단날들 사이의 간격이 일정하게 유지될 수 있게한 유격조절장치를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a clearance adjustment device that allows the interval between cutting blades to be kept constant in a steel cutting device.

상기의 과제를 달성하기 위한 본 발명에 따른 유격조절장치는 상기 회전축과 몸체부재 사이에 회전가능하도록 개재되고, 일측은 상기 회전부재에 접촉되도록 형성된 지지부재와, 상기 회전축의 적어도 일부가 수용되도록 형성되고, 상기 몸체부재와 상기 지지부재에 일측이 각각 결합된 커버부재와, 상기 몸체부재와 상기 커버부재 사이에 개재되고, 개재된 개수에 따라 상기 지지부재와 상기 회전부재 사이의 유격이 조절될 수 있게 하는 적어도 하나의 탄성부재를 포함한다.The clearance adjusting device according to the present invention for achieving the above object is interposed so as to be rotatable between the rotating shaft and the body member, one side is formed to be in contact with the rotating member, and formed to accommodate at least a portion of the rotating shaft. And a cover member having one side coupled to the body member and the support member, and interposed between the body member and the cover member, and the clearance between the support member and the rotating member may be adjusted according to the interposed number. At least one elastic member.

본 발명에 따른 유격조절장치는 탄성부재의 개수를 조절하여 회전부재와 지지부재 사이의 유격을 용이하게 제거할 수 있다. 이에 따라, 회전부재가 회전축을 따라 이동되지 않음으로써, 피절단물을 절단하기 위해 회전부재가 회전되어 과정에서 제1절단부와 제2절단부들 사이의 간격이 일정하게 유지될 수 있다.The clearance adjusting device according to the present invention can easily remove the clearance between the rotating member and the support member by adjusting the number of elastic members. Accordingly, since the rotating member is not moved along the rotating shaft, the rotating member is rotated to cut the cutting object, so that the distance between the first cutting portion and the second cutting portions can be kept constant in the process.

또한, 유격조절장치는 지지부재에 대한 커버부재의 밀착된 정도에 따라 몸체부재와 회전부재의 간격을 조절하여 제1절단부와 제2절단부의 유격을 미세하게 조절할 수 있으므로, 철재절단장치의 절단성능을 향상시킬 수 있을 뿐만 아니라, 종래의 철재절단장치와 다르게 몸체부재의 제2절단부와 회전부재의 제1절단부 사이에 철재가 끼이는 것을 방지할 수 있다.In addition, the clearance adjusting device may finely control the clearance between the first cutting portion and the second cutting portion by adjusting the distance between the body member and the rotating member according to the degree of close contact of the cover member with respect to the supporting member, and thus the cutting performance of the steel cutting device. In addition to improving the conventional steel cutting device, it is possible to prevent the iron from being caught between the second cutting portion of the body member and the first cutting portion of the rotating member.

또한, 철재절단장치 전체를 분해하지 않고, 커버부재만 분리하여 탄성부재의 개수를 조절할 수 있으므로, 유격 보정으로 인해 절단 작업이 장시간 멈추게 되는 일이 없어지게 되어 장비의 가동 효율을 높일 수 있다.In addition, since the number of elastic members can be adjusted by separating only the cover member without disassembling the entire steel cutting device, the cutting operation is not stopped for a long time due to the clearance correction, thereby increasing the operating efficiency of the equipment.

이하 첨부된 도면에 따라서 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다. 본 발명의 유격조절장치를 설명하기에 앞서, 철재절단장치의 구조의 일예를 설명한다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail. Before explaining the play control device of the present invention, an example of the structure of the steel cutting device will be described.

도 1 및 도 2를 참조하면, 철재절단장치(10)는 회전부재(20)와, 몸체부재(30)와, 회전축(40)을 포함한다.1 and 2, the steel cutting device 10 includes a rotating member 20, a body member 30, and a rotating shaft 40.

회전부재(20)에는 제1절단부(21)가 형성된다. 더욱 바람직하게, 회전부재(20)의 일단에는 제1절단부(21)가 형성된다. 제1절단부(21)일예로 금속재질의 절단날일 수 있다. 회전부재(20)의 타단에는 유압실린더(50)가 회전가능하게 결합될 수 있다. 유압실린더(50)는 회전부재(20)가 일정 각도로 회전 왕복운동 할 수 있게 한다. 단, 회전부재(20)의 타단에 유압실린더(50)가 결합된 것으로 한정하지는 않으며, 회전부재(20)를 회전 왕복운동 시킬 수 있는 것이면 어느 것을 사용하여도 무방하다. The first cutting portion 21 is formed in the rotating member 20. More preferably, the first cutting portion 21 is formed at one end of the rotating member 20. For example, the first cutting part 21 may be a cutting blade made of metal. The other end of the rotating member 20 may be coupled to the hydraulic cylinder 50 rotatably. The hydraulic cylinder 50 allows the rotating member 20 to rotate reciprocate at a predetermined angle. However, the hydraulic cylinder 50 is not limited to the other end of the rotating member 20, and any one may be used as long as the rotating member 20 can reciprocate the rotation.

몸체부재(30)에는 제2절단부(31)가 형성된다. 이러한 몸체부재(30)는 회전부재(20)의 양면을 감싸도록 형성된다. 여기서, 제2절단부(31)는 회전부재(20)가 회전 왕복운동함에 따라 제1절단부(21)와 가까워지거나 멀어지게 된다. 제2절단부(31)일예로 금속재질의 절단날일 수 있다.The second cut portion 31 is formed in the body member 30. The body member 30 is formed to surround both sides of the rotating member 20. Here, the second cutting portion 31 is closer to or away from the first cutting portion 21 as the rotating member 20 rotates reciprocally. For example, the second cutting part 31 may be a cutting blade made of metal.

철재절단장치(10)는 유압실린더(50)의 신장 및 수축에 의해 제1절단부(21)와 제2절단부(31)가 매우 인접하게 위치된 상태에서 철재의 절단이 이루어진다. 회전축(40)은 몸체부재(30)에 대해 회전부재(20)가 회전될 수 있도록 형성된다. 즉, 회전축(40)은 몸체부재(30)의 일측과, 회전부재(20)와, 몸체부재(30)의 타측을 관통하게 결합된다. 본 발명의 유격조절장치는 제1절단부(21)와 제2절단부(31) 사이의 간격이 일정하게 유지되게 하여 철재절단장치(10)에서 철재의 절단이 안정적으로 처리될 수 있게 한다.The steel cutting device 10 is cut in the steel in a state where the first cutting portion 21 and the second cutting portion 31 are located very close by the expansion and contraction of the hydraulic cylinder (50). The rotating shaft 40 is formed so that the rotating member 20 can be rotated with respect to the body member 30. That is, the rotating shaft 40 is coupled to penetrate one side of the body member 30, the rotating member 20 and the other side of the body member 30. The clearance adjusting device of the present invention maintains a constant gap between the first cutting portion 21 and the second cutting portion 31 so that the cutting of the steel in the steel cutting device 10 can be stably processed.

본 발명의 바람직한 일실시예에 따른 유격조절장치는 지지부재(110)와, 커버부재(120)와, 탄성부재(130)를 포함한다.The clearance adjusting device according to the preferred embodiment of the present invention includes a support member 110, a cover member 120, and an elastic member 130.

지지부재(110)는 회전축(40)과 몸체부재(30) 사이에 회전가능하도록 개재된다. 지지부재(110)의 일측은 회전부재(20)에 접촉되도록 배치된다. 즉, 지지부재(110)에는 중공이 형성되고, 중공의 내경은 회전축(40)의 직경과 대응되는 크기로 형성된다. 더욱 바람직하게 유격조절장치는 2개의 지지부재(110)를 포함할 수 있다. 각각의 지지부재(110)는 회전축(40)에 회전가능하게 결합되고, 회전부재(20)를 기준으로 회전부재(20)의 양면에 각각 배치된다.The support member 110 is interposed so as to be rotatable between the rotation shaft 40 and the body member 30. One side of the support member 110 is disposed to contact the rotating member 20. That is, the hollow is formed in the support member 110, the inner diameter of the hollow is formed to a size corresponding to the diameter of the rotating shaft (40). More preferably, the clearance adjusting device may include two support members 110. Each support member 110 is rotatably coupled to the rotation shaft 40, and are disposed on both sides of the rotation member 20 based on the rotation member 20.

커버부재(120)는 회전축(40)의 적어도 일부가 수용되도록 형성된다. 그리고, 커버부재(120)의 일측은 몸체부재(30)와 지지부재(110)에 각각 결합된다. 즉, 커버부재(120)는 철재절단장치(10)의 몸체부재(30)에서 회전축(40)이 관통되는 부분에 결합된다. 커버부재(120)와 몸체부재(30), 커버부재(120)와 지지부재(110)의 결합은 볼트에 의해 체결될 수 있다. 단, 커버부재(120)와 몸체부재(30), 커버부재(120)와 지지부재(110)의 결합을 볼트로 한정하지는 않는다.The cover member 120 is formed to accommodate at least a portion of the rotation shaft 40. And, one side of the cover member 120 is coupled to the body member 30 and the support member 110, respectively. That is, the cover member 120 is coupled to a portion through which the rotating shaft 40 passes through the body member 30 of the steel cutting device 10. The combination of the cover member 120 and the body member 30, the cover member 120 and the support member 110 may be fastened by a bolt. However, the coupling of the cover member 120 and the body member 30, the cover member 120 and the support member 110 is not limited to the bolt.

상기와 같은 구조로 이루어진 커버부재(120)는 지지부재(110)가 외부로 분리되는 것을 방지한다. 또한, 커버부재(120)는, 후술한 탄성부재(130)가 외부로 분리되는 것을 방지한다. 또한, 커버부재(120)에는 회전축(40)이 고정 결합됨으로써, 커버부재(120)에 의해 회전축(40)의 회전이 방지될 수 있다.The cover member 120 having the structure as described above prevents the support member 110 from being separated outward. In addition, the cover member 120 prevents the elastic member 130 described later from being separated to the outside. In addition, since the rotating shaft 40 is fixedly coupled to the cover member 120, the rotation of the rotating shaft 40 may be prevented by the cover member 120.

탄성부재(130)는 몸체부재(30)와 커버부재(120) 사이에 개재된다. 탄성부재(130)가 몸체부재(30)와 커버부재(120) 사이에 개재된 개수에 따라 지지부재(110)와 회전부재(20) 사이의 유격이 조절될 수 있다. 탄성부재(130)에 의해 지지부재(110)와 회전부재(20) 사이의 유격이 조절되는 것은 후술하기로 한다. 탄성부재(130)는 몸체부재(30)와 커버부재(120) 사이에 하나 또는 복수개가 개재될 수 있다. 이러한 탄성부재(130)의 일예로 와셔일 수 있다.The elastic member 130 is interposed between the body member 30 and the cover member 120. The clearance between the support member 110 and the rotation member 20 may be adjusted according to the number of elastic members 130 interposed between the body member 30 and the cover member 120. The clearance between the support member 110 and the rotating member 20 by the elastic member 130 will be described later. One or more elastic members 130 may be interposed between the body member 30 and the cover member 120. One example of such an elastic member 130 may be a washer.

상기와 같은 구조로 이루어진 유격조절장치에 의해 철재절단장치(10)의 제1절단부(21)와 제2절단부(31) 사이의 간격이 일정하게 유지되는 것을 설명한다. 철재 등의 피절단물을 절단하기 위하여 철재절단장치(10)가 동작되는 과정에서 회전부재(20)가 특정 각도로 회전 왕복하게 된다. 여기서, 지지부재(110)는 회전되지 않으므로 지지부재(110)와 회전부재(20)가 접촉되는 면들(22, 112)이 서로 마찰된다. 이에 따라, 각각의 면들(22, 112)에 마모가 발생되고, 지지부재(110)와 회전부재(20) 사이에 유격이 발생하게 된다. 이 경우, 지지부재(110)와 회전부재(20)가 마모되어 서로 이격된 거리만큼 적어도 하나 이상의 탄성부재(130)를 제거한다. 이에 따라, 커버부재(120)가 회전부재(20)측으로 이동하게 되고, 커버부재(120)가 지지부재(110)를 회전부재(20)측으로 이동시켜서 지지부재(110)와 회전부재(20) 사이의 유격이 제거될 수 있다. 즉, 철재절단장치(10) 전체를 분해하지 않고도 간단하게 유격을 보정할 수 있다.It will be described that the gap between the first cutting portion 21 and the second cutting portion 31 of the steel cutting device 10 is maintained constant by the play control device having the structure as described above. In order to cut the cutting object such as steel, the rotating member 20 is rotated back and forth at a specific angle in the process of operating the steel cutting device 10. Here, since the support member 110 is not rotated, the surfaces 22 and 112 on which the support member 110 and the rotating member 20 contact each other are rubbed with each other. Accordingly, wear occurs on each of the surfaces 22 and 112, and play is generated between the support member 110 and the rotating member 20. In this case, the support member 110 and the rotating member 20 are worn to remove the at least one elastic member 130 by a distance spaced from each other. Accordingly, the cover member 120 is moved to the rotating member 20 side, the cover member 120 to move the support member 110 to the rotating member 20 side to support member 110 and the rotating member 20 Gaps between can be eliminated. That is, the clearance can be easily corrected without disassembling the entire steel cutting device 10.

전술한 바와 같이 유격조절장치는 탄성부재(130)의 개수를 조절하는 것 만으로 회전부재(20)와 지지부재(110) 사이의 유격을 용이하게 제거할 수 있다. 이와 같이 회전부재(20)와 지지부재(110) 사이의 유격이 제거되어 회전부재(20)가 회전축(40)을 따라 이동되지 않음으로써, 피절단물을 절단하기 위해 회전부재(20)가 회전되는 과정에서 제1절단부(21)와 제2절단부(31)들 사이의 간격이 일정하게 유지될 수 있다.As described above, the clearance adjusting device may easily remove the clearance between the rotating member 20 and the supporting member 110 only by adjusting the number of the elastic members 130. In this way, the play between the rotating member 20 and the support member 110 is removed so that the rotating member 20 does not move along the rotating shaft 40, so that the rotating member 20 rotates to cut the cutting object. In the process, the interval between the first cutout portion 21 and the second cutout portion 31 may be kept constant.

또한, 유격조절장치는 지지부재(110)에 대한 커버부재(120)의 밀착된 정도에 따라 몸체부재(30)와 회전부재(20)의 간격을 조절하여 제1절단부(21)와 제2절단부(31)의 유격을 미세하게 조절할 수 있으므로, 철재절단장치(10)의 절단성능을 향상시킬 수 있을 뿐만 아니라, 종래의 철재절단장치(10)와 다르게 몸체부재(30)의 제2절단부(31)와 회전부재(20)의 제1절단부(21) 사이에 철재가 끼이는 것을 방지할 수 있다. 여기서, 지지부재(110)에 대한 커버부재(120)의 밀착 정도는 몸체부재(30)와 커버부재(120) 사이에 개재된 탄성부재(130)의 개수를 조절하여 제어될 수 있다. 또한, 지지부재(110)에 대한 커버부재(120)의 밀착된 정도는 지지부재(110)와 커버부재(120)를 체결하는 볼트를 조이거나 풀어서 제어되는 것도 가능할 수 있다.In addition, the play control device adjusts the distance between the body member 30 and the rotating member 20 according to the degree of close contact of the cover member 120 with respect to the support member 110, the first cutting portion 21 and the second cutting portion. Since the play of the 31 can be finely adjusted, not only can the cutting performance of the steel cutting device 10 be improved, but also the second cutting portion 31 of the body member 30 is different from the conventional steel cutting device 10. ) Between the first cutting portion 21 of the rotating member 20 can be prevented. Here, the degree of adhesion of the cover member 120 to the support member 110 may be controlled by adjusting the number of elastic members 130 interposed between the body member 30 and the cover member 120. In addition, the degree of close contact of the cover member 120 with respect to the support member 110 may be controlled by tightening or loosening the bolts connecting the support member 110 and the cover member 120.

또한, 철재절단장치(10) 전체를 분해하지 않고, 커버부재(120)만 분리하여 탄성부재(130)의 개수를 조절할 수 있으므로, 유격 보정으로 인해 절단 작업이 장시간 멈추게 되는 일이 없어지게 되어 장비의 가동 효율을 높일 수 있다.In addition, since the number of the elastic members 130 can be adjusted by separating only the cover member 120 without disassembling the entire steel cutting device 10, the cutting operation is not stopped for a long time due to the clearance correction. Can increase the operating efficiency.
