Description
본 고안은 작업롤의 와이퍼장치에 관한 것으로, 특히 열연공정에서 사용되는 작업롤에 축방향으로 에어튜브에 의해 탄성 밀착되면서 롤냉각수헤더로부터 분사되는 냉각수가 필요개소 이외로 낙수되는 현상을 완벽하게 방지할 수 있는 작업롤의 와이퍼장치에 관한 것이다.The present invention relates to a wiper device of a work roll, and particularly prevents the falling of the coolant sprayed from the roll coolant header while falling elastically close to the work roll used in the hot rolling process by the air tube in the axial direction. The wiper apparatus of the work roll which can be performed.
일반적으로 열연압연의 작업롤에 분사되는 냉각수가 열연강판에 누수 또는 낙수에 의해 공급될 경우 제품의 형상 또는 품질에 악영향을 미치게 된다.In general, when the cooling water sprayed on the hot rolled work roll is supplied to the hot rolled steel sheet by leakage or falling water, it adversely affects the shape or quality of the product.
따라서 종래의 작업롤 와이퍼장치는 도1 및 도2에 도시한 바와같이 받침판(20)의 상부에 부착된 와이퍼(3)가 회전되는 작업롤(1)의 외주면에 축방향으로 밀착되고, 이로써 작업롤을 향해 롤냉각수헤더(2)로부터 분사되는 냉각수가 열연강판(6)의 상면으로 낙수되지 않게 된다.Therefore, in the conventional work roll wiper device, as shown in FIGS. 1 and 2, the wiper 3 attached to the upper portion of the support plate 20 is axially in close contact with the outer circumferential surface of the work roll 1 on which the work roll 1 is rotated. The cooling water sprayed from the roll cooling water header 2 toward the roll does not fall to the upper surface of the hot rolled steel sheet 6.
그러나 종래의 와이퍼(3)는 그 재질이 딱딱한 재질로 이루어져 있기 때문에 작업롤(1)과의 밀착성이 불량하여 누수를 발생시키고, 작업롤과의 마찰에 의해 쉽게 파손되며, 받침판(20)에 다수의 볼트에 의해 고정되기 때문에 취부 및 취외시 번거로움이 발생된다.However, since the conventional wiper 3 is made of a hard material, the adhesion to the work roll 1 is poor, which causes water leakage, and is easily damaged by friction with the work roll. Since it is fixed by the bolt of the hassle occurs during mounting and removal.
본 고안은 열연공정에서 사용되는 작업롤에 축방향으로 에어튜브에 의해 탄성 밀착되면서 롤냉각수헤더로부터 분사되는 냉각수가 필요개소 이외로 낙수되는 현상을 완벽하게 방지할 수 있는 작업롤의 와이퍼장치를 제공함에 그 목적이 있다.The present invention provides a wiper device for a work roll that can completely prevent the falling of coolant sprayed from the roll cooling water header while being elastically in close contact with the work roll used in the hot rolling process by an air tube in an axial direction. Has its purpose.

상기한 목적을 달성하기 위하여 본 고안은 작업롤의 와이퍼장치에 있어서, 받침판의 상면 전방측에 고정 설치되는 지지커버와; 상기 지지커버에 에어가 충전되는 고무튜브에 의해 전후이동되도록 내장되는 밀판과; 상기 지지커버에 상기 밀판에 의해 전후이동되도록 내장되는 와이퍼와; 고정블록에 회전 가능하도록 결합되는 지지축의 상단에 고정되면서 상기 와이퍼의 양측면을 지지하는 고정패드로 구성되는 것을 특징으로 하는 작업롤의 와이퍼장치를 제공한다.In order to achieve the above object, the present invention provides a wiper device for a work roll, the support cover being fixedly installed on the front surface of the support plate; A sealing plate which is built to be moved back and forth by a rubber tube filled with air in the support cover; A wiper embedded in the support cover to be moved back and forth by the contact plate; It is fixed to the upper end of the support shaft is rotatably coupled to the fixed block provides a wiper device of the work roll, characterized in that consisting of a fixed pad for supporting both sides of the wiper.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
도3은 본 고안에 따른 작업롤의 와이퍼장치를 나타내는 요부사시도이고, 도4는 도3의 X-X단면도이며, 도5는 도4의 Y-Y단면도이다.Figure 3 is a main perspective view showing a wiper device of the work roll according to the present invention, Figure 4 is an X-X cross-sectional view of Figure 3, Figure 5 is a Y-Y cross-sectional view of FIG.
받침판(20)의 상면에 부착되는 지지커버(17)에는 그 후방측에 대략 ㄴ자형의 밀판(12)이 전후진 가능하도록 내장되어 있고, 이 밀판(12)의 상부에는 전후측고무튜브(7-1,7-2)(13)가 좌우 길이방향으로 설치되어 있다.In the support cover 17 attached to the upper surface of the support plate 20, a substantially N-shaped contact plate 12 is built in the rear side thereof so as to be able to move forward and backward, and the upper and rear side rubber tubes 7 -1,7-2) 13 are provided in the left-right direction.
이때 전후측고무튜브(7-1,7-2)(13) 사이에는 칸막이판(14)이 끼워져 있고, 전후측고무튜브(7-1,7-2)(13)에 각각 공기가 공급되면 팽창되면서 후방측고무튜브(13)가 칸막이판을 밀어 전방측고무튜브(7-1,7-2)를 밀게 되고, 동시에 밀판(12)이 전방측으로 전진되면서 와이퍼(11)를 밀게 된다.At this time, the partition plate 14 is sandwiched between the front and back side rubber tubes 7-1, 7-2 and 13, and air is supplied to the front and back side rubber tubes 7-1, 7-2 and 13, respectively. While expanding, the rear side rubber tube 13 pushes the partition plate to push the front side rubber tubes 7-1 and 7-2, and simultaneously pushes the wiper 11 while the plate 12 is advanced to the front side.
또한 받침판(20)의 상면 전방측에는 라이너(19)가 부착되어 있고, 지지커버(17)의 내측면 전방에 정지턱(15)이 고정되어 있다.In addition, a liner 19 is attached to the front side of the upper surface of the support plate 20, and the stop jaw 15 is fixed to the front side of the inner side of the support cover 17.
여기서 지지커버(17)에 내장되는 와이퍼(11)는 라이너(19)의 상면을 따라 전후진되면서 정지턱(15)에 의해 지지커버로부터의 탈락이 방지된다.Here, the wiper 11 embedded in the support cover 17 is moved forward and backward along the upper surface of the liner 19 to prevent the fall from the support cover by the stop jaw 15.
한편 공기공급관(16)은 지지커버(17)의 후방측면을 관통하여 전후측고무튜브(7-1,7-2)(13)의 양단에 연결되어 있다.Meanwhile, the air supply pipe 16 penetrates the rear side of the support cover 17 and is connected to both ends of the front and rear rubber tubes 7-1, 7-2 and 13.
그리고 지지커버(17)의 좌우측면과 약간 이격되도록 받침판(20)의 상면에 부착되는 고정블록(26)에는 지지축(25)의 하단이 회전 가능하도록 결합되고, 지지축(25)에는 그 상단에 고정패드(18)가 각각 고정되어 있다.The lower end of the support shaft 25 is rotatably coupled to the fixed block 26 attached to the upper surface of the support plate 20 so as to be slightly spaced apart from the left and right sides of the support cover 17, and the upper end thereof to the support shaft 25. The fixing pads 18 are respectively fixed to the ends.
이때 와이퍼(11)의 양측면에 각각 밀착되는 고정패드(18)는 그 전방측이 와이퍼보다 돌출되도록 설치되어 작업롤(1)의 양측면에 동시에 밀착된다.At this time, the fixing pads 18 which are in close contact with both side surfaces of the wiper 11 are installed so that the front side thereof protrudes more than the wiper, and are in close contact with both sides of the work roll 1 at the same time.
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
먼저 받침판(20)이 냉각수의 낙수방지를 위해 작업롤(1)에 접근하게 되고, 받침판의 전단이 균형추(5)에 의해 중심축(4)을 중심으로 상승하게 되며, 이때 고정패드(18)가 작업롤(1)의 양측면에 밀착되면서 와이퍼(11)의 전단면이 작업롤(1)의 외주면에 축방향으로 밀착된다.First, the support plate 20 approaches the work roll 1 to prevent the fall of the coolant, and the front end of the support plate is raised about the central axis 4 by the counterweight 5, wherein the fixed pad 18 Is in close contact with both sides of the work roll 1, the front end face of the wiper 11 is in close contact with the outer peripheral surface of the work roll 1 in the axial direction.
이때 공기공급관(16)을 통해 저압의 압축공기를 공급하게 되면 고무튜브(7-1,7-2,13)가 팽창되면서 칸막이판(14)과 밀판(12)을 전방측으로 밀게 되고, 이로써 와이퍼(11)는 전진되면서 전단면이 작업롤(1)의 외주면에 균일한 힘으로 밀착되어 냉각수의 낙수방지를 완벽하게 수행하게 된다.At this time, when compressed air of low pressure is supplied through the air supply pipe 16, the rubber tubes 7-1, 7-2, 13 are expanded, and the partition plate 14 and the push plate 12 are pushed to the front side. (11) as the shear surface is in close contact with a uniform force to the outer peripheral surface of the work roll (1) to perform a perfect fall prevention of the coolant.
한편 작업중에는 지지축(52)을 수평상태로 전환하여 고정패드(18)가 각각 와이퍼(11)의 양측면에 밀착되도록 하고, 와이퍼를 교환 또는 보수하고자할 경우 지지축을 수직상태로 전환하여 와이퍼의 양측면으로부터 고정패드를 분리하면서 와이퍼를 좌우측으로 밀거나 당겨서 지지커버(17)로부터 빼내어 교환 또는 보수를 하게 된다.On the other hand, during operation, the support shaft 52 is shifted to the horizontal state so that the fixing pads 18 are brought into close contact with both sides of the wiper 11, and when the wiper is to be replaced or repaired, the support shaft is switched to the vertical state to both sides of the wiper. The wiper is pushed to the left or right and pulled out of the support cover 17 while the fixing pad is removed from the support cover 17 for replacement or repair.
본 고안은 열연공정에서 사용되는 작업롤에 축방향으로 에어튜브에 의해 탄성 밀착되면서 롤냉각수헤더로부터 분사되는 냉각수가 필요개소 이외로 낙수되는 현상을 완벽하게 방지함으로써 냉각수에 의한 열연강판의 품질저하를 방지하고, 와이퍼의 수명을 연장하면서 교체와 보수가 용이한 효과를 제공한다.The present invention is designed to completely reduce the quality of the hot rolled steel sheet by the cooling water by completely preventing the falling of the coolant sprayed from the roll cooling water header while being elastically in close contact with the work roll used in the hot rolling process by the air tube. Prevents and extends the life of the wiper while providing an easy replacement and repair.
