본 발명은 압연롤 표면 연마장치에 관한 것으로, 보다 상세하게는 압연롤 표면을 균일하게 연마시킴과 동시에 발생된 폐기물이 막히지 않고 용이하게 배출처리될 수 있도록 개선된 압연롤 표면 연마장치에 관한 것이다.The present invention relates to a rolling roll surface polishing apparatus, and more particularly, to an improved rolling roll surface polishing apparatus so as to uniformly polish the surface of the rolling roll and at the same time, the generated waste can be easily discharged without being blocked.

일반적으로, 냉간압연을 통한 강판의 표면품위는 압연롤의 표면 연마균일도에 의해 좌우된다고 해도 과언이 아니다.In general, it is no exaggeration to say that the surface quality of the steel sheet through cold rolling depends on the surface polishing uniformity of the rolling roll.

즉, 압연롤의 표면이 편차없이 미려하게 연마되어 있어야만 압연후 고품위의 표면품질을 갖는 강판을 얻을 수 있게 된다.That is, the surface of the rolling roll should be polished beautifully without any variation to obtain a steel sheet having a high quality surface quality after rolling.

이를 위해, 압연롤은 주기적으로 표면 연마작업을 거쳐 연마되게 된다.To this end, the rolling rolls are periodically polished by surface polishing.

그런 후, 압연롤(1) 표면에 잔류하는 연마가루를 제거하기 위해 세척수(3)를 분사하는 형태로 작업되었다.Then, it was worked in the form of spraying the washing water (3) to remove the abrasive powder remaining on the rolling roll (1) surface.

그러나, 이와 같은 방식은 연마작업이 전량 수작업에 의해 이루어져야 하므로 작업능률이 떨어지고, 작업이 어려우며, 수작업에 의해 표면이 연마되는 것이므로 표면 균일도가 떨어지고, 또한 세척시 발생된 연마가루가 수조(2)의 마닥에 침전되어 침전물(5)을 형성하면서 배출구(6)를 폐쇄시켜 배수 불량의 문제도 유발되었다.However, in such a method, since the polishing work must be performed by hand, the work efficiency is reduced, the work is difficult, and the surface is polished by hand, so that the surface uniformity is reduced, and the polishing powder generated during the washing is applied to the tank 2. It precipitated on the floor and formed a sediment (5), closing the outlet (6) also caused a problem of poor drainage.

여기에서, 상기 구동모터(600)는 상기 고정베이스(120)중 어느 하나에 고정되고, 상기 회전축(620)에는 구동축(310)이 연결된다.Here, the drive motor 600 is fixed to any one of the fixed base 120, the drive shaft 310 is connected to the rotary shaft 620.

상기 회전축(620)과 구동축(310)은 스플라인 방식으로 서로 연결될 수도 있고, 또한 커플러를 통해 연결될 수도 있다.The rotation shaft 620 and the driving shaft 310 may be connected to each other in a spline manner, or may be connected through a coupler.

뿐만 아니라, 상기 구동축(310)의 길이 일부에는 일정각도로 경사설치된 회전원판(320)이 일체로 고정된다.In addition, the rotation disc 320 inclined at a predetermined angle is fixed to a part of the length of the drive shaft 310 integrally.

상기 회전원판(320)은 상기 구동축(310)의 길이방향을 따라 일정간격을 두고 적어도 2개 이상 설치됨이 바람직하다.Preferably, at least two rotation discs 320 are installed at predetermined intervals along the longitudinal direction of the drive shaft 310.

그리고, 상기 회전원판(320)의 외주면, 즉 테두리는 각각 상기 연마안내축(210)과 교반안내축(410)에 끼워진 연마고정대(220) 및 교반고정대(420)와 동시에 맞물리도록 설치된다.In addition, the outer circumferential surface, that is, the edge of the rotating disc 320 is installed to engage with the polishing guide 220 and the stirring guide 420 respectively fitted to the polishing guide shaft 210 and the stirring guide shaft 410, respectively.

이를 위해, 상기 연마고정대(220)와 교반고정대(420)가 상기 회전원판(320)과 접촉되는 면에는 상기 회전원판(320)의 외주면에 대응되는 형상의 홈(222,422)이 형성된다.To this end, grooves 222 and 422 having a shape corresponding to the outer circumferential surface of the rotating disk 320 are formed on the surface where the polishing fixing plate 220 and the stirring fixing table 420 are in contact with the rotating disk 320.

이때, 상기 홈(222,422)은 대략 반구형상으로 형성되고, 상기 회전원판(320)의 외주면, 즉 테두리는 상기 홈(222,422)에 볼죠인트 형태로 결합될 수 있도록 구형상으로 형성된다.In this case, the grooves 222 and 422 are formed in a substantially hemispherical shape, and the outer circumferential surface of the rotating disc 320, that is, the edge, is formed in a spherical shape so as to be coupled to the grooves 222 and 422 in the form of a ball joint.

그리고, 상기 연마고정대(220)는 고정봉(230)에 용접고정되거나 혹은 보조판에 의해 볼트체결되는 형태를 가질 수 있고, 상기 고정봉(230)은 상기 연마안내축(210)에 끼워져 좌우 이동가능하게 설치될 수 있다.In addition, the polishing fixture 220 may have a form fixed by welding to the fixing rod 230 or bolted by an auxiliary plate, the fixing rod 230 is fitted to the polishing guide shaft 210 to move left and right Can be installed.

뿐만 아니라, 상기 연마고정대(220)는 그 일면이 대략 반원형상으로 형성됨이 바람직하고, 그 면에는 상기 압연롤(R)의 표면과 접촉되는 연마포(240)가 고정됨이 바람직하다.In addition, the polishing fixture 220 is preferably one surface is formed in a substantially semi-circular shape, the surface is preferably a polishing cloth 240 in contact with the surface of the rolling roll (R) is fixed.

따라서, 상기 연마포(240)는 상기 연마고정대(220)의 슬라이딩과 동시에 함께 슬라이딩되면서 상기 압연롤(R)의 표면을 연마하게 된다.Therefore, the polishing cloth 240 is polished while sliding together with the sliding of the polishing fixture 220 to polish the surface of the rolling roll (R).

또한, 상기 교반고정대(420)도 앞서 설명한 연마고정대(220)와 유사한 형태로 교반안내축(410)에 이동가능하게 끼워 설치될 수 있다.In addition, the stirring fixture 420 may also be installed to be inserted into the stirring guide shaft 410 in a similar form to the above-described polishing fixture 220.

나아가, 상기 교반고정대(420)는 대략 사각판상으로 형성되며, 그 일단 즉, 상기 수조(100)의 길이방향쪽 단부는 라운드지게 절곡되어 상기 수조(100)의 테두리에 걸치도록 배치됨이 바람직하다.Further, the stirring fixture 420 is formed in a substantially rectangular plate shape, that is, one end, that is, the longitudinal end of the water tank 100 is bent round to be arranged to span the edge of the water tank 100.

뿐만 아니라, 상기 교반고정대(420)의 하단면에는 일정간격을 두고 다수의 교반편(430)이 일체로 고정된다.In addition, a plurality of stirring pieces 430 are fixed to the bottom surface of the stirring fixture 420 at a predetermined interval integrally.

상기 교반편(430)은 반원형상으로 형성됨이 바람직하나 반드시 이에 국한되지 않고 사각형상을 비롯한 다양한 형태로 변형가능함은 물론이다.The stirring piece 430 is preferably formed in a semi-circular shape, but is not necessarily limited thereto, and may be modified in various forms including a rectangular shape.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

먼저, 표면 연마를 위해 압연롤(R)을 수조(100)에 안착시킨 후 그 일단에 종동풀리(P)를 고정하게 된다.First, the rolling roll R is seated in the water tank 100 for surface polishing, and then the driven pulley P is fixed to one end thereof.

종동풀리(P)가 고정되면 벨트(500)를 걸어 구동풀리(610)와 연결하게 된다.When the driven pulley P is fixed, the belt 500 is connected to the driving pulley 610.

이어, 구동모터(600)를 회전시키게 되면 구동축(310)이 회전되고, 이와 일체로 고정된 회전원판(320)도 회전하게 된다.Subsequently, when the driving motor 600 is rotated, the driving shaft 310 is rotated, and the rotating disc 320 fixed thereto is also rotated.

이때, 상기 회전원판(320)은 상기 구동축(310)에 대해 경사지게 고정되어 있으므로 이와 결합된 연마고정대(220) 및 교반고정대(420)가 상기 회전원판(320)과의 경사에 의해 생긴 편차만큼 좌우로 왕복운동하게 된다.At this time, the rotation disc 320 is fixed to the drive shaft 310 inclined so that the left and right grinding rod 220 and the stirring guide 420 coupled to the rotation disc 320 by the deviation caused by the inclination with the rotation disc 320 To reciprocate.

즉, 회전원판(320)의 구동에 따라 연마고정대(220)와 교반고정대(420)는 서로 엇갈린 상태로 좌우로 왕복운동하게 된다.That is, as the rotary disk 320 is driven, the grinding fixing table 220 and the stirring fixing table 420 reciprocate from side to side in a staggered state.

동시에, 상기 연마고정대(220)에 부착된 연마포(240)는 회전되고 있는 압연롤(R)의 표면을 좌우방향으로 스윕(Swip)하면서 연마하게 됨은 물론 균일압력이 가 해지므로 그 표면을 항상 고르게 연마하게 된다.At the same time, the polishing cloth 240 attached to the polishing fixture 220 is not only polished while sweeping the surface of the rolling roll R which is being rotated in left and right directions, but also a uniform pressure is applied to the surface. Grind evenly.

뿐만 아니라, 상기 교반고정대(420)의 하면에 고정된 반원형상의 교반편(430)은 좌우 왕복을 통해 수조(100)내 물과 부유된 연마부스러기를 유동시켜 침전되지 못하도록 함으로써 배출관(110)의 막힘 현상도 억제하게 된다.In addition, the semi-circular stirring piece 430 fixed to the lower surface of the stirring fixture 420 is blocked by the discharge pipe 110 by preventing the water and the suspended abrasive debris from flowing in the water tank 100 through the left and right reciprocation to prevent sedimentation. The phenomenon is also suppressed.

나아가, 상기 교반고정대(420)는 그 일측 변이 상기 수조(100)의 상단 테두리 일부에 걸쳐 있으므로 교반고정대(420)의 회전이 억제된 상태로 그 왕복운동을 원활하게 가이드하게 된다.In addition, the stirring fixture 420 is smoothly guides its reciprocating motion with its one side extending over a portion of the upper edge of the water tank 100 while the rotation of the stirring fixture 420 is suppressed.

이상에서 상세히 설명한 바와 같이, 본 발명은 압연롤 표면을 연마할 때에 균일압을 가하는 기계적 수단을 통해 연마함으로써 그 표면을 보다 균일하고 미려하게 연마할 수 있음은 물론 동시에 수조내 용액을 교반시키도록 하여 침전물의 생성을 억제함으로써 배출관 막힘현상도 방지하게 된다.As described in detail above, the present invention allows the surface of the rolling roll to be polished more uniformly and beautifully by polishing through a mechanical means applying a uniform pressure, and at the same time, the solution in the water tank is stirred. By suppressing the formation of sediment, it is also possible to prevent the discharge pipe blockage.
