본 발명은 열간압연과정에서 형성되는 강판의 벤딩부를 교정하여 열간교정기로 치입시키는 유도장치에 관한 것으로, 특히 열간압연과정에서 강판의 선후단부에 발생되는 벤딩부를 밀면서 눌러서 열간교정기로 치입시킬 수 있도록 된 벤딩강판의 자동 유도 장치에 관한 것이다. The present invention relates to an induction apparatus for calibrating the bending portion of the steel sheet formed in the hot rolling process to be inserted into the hot calibrator, in particular pushed while pressing the bending portion generated in the front and rear ends of the steel sheet during the hot rolling process to be inserted into the hot calibrator It relates to an automatic guide device for bending steel sheet.

일반적으로, 슬라브 등과 같은 소재를 가열로에서 일정온도(1250℃)로 가열하고 압연기에서 목표로하는 두께 또는 폭으로 압연하여 강판으로 제조하는데, 이러한 열간압연에 의해 제조되는 강판은 냉각장치와 열간교정기를 거치면서 수평상태로 교정되어 후처리공정으로 이송된다. In general, steel sheets are heated to a predetermined temperature (1250 ° C.) in a furnace and rolled to a thickness or width desired by a rolling mill to produce a steel sheet. The steel sheet manufactured by such hot rolling is a cooling device and a hot calibrator. It is calibrated in a horizontal state while passing through to the aftertreatment process.

그러나, 압연라인에서 제조되는 강판은, 열간압연기용 상하부롤의 직경편차와 강판상하면의 온도차이 및 패스라인 등의 주변여건으로 인해 상하방향으로 벤딩부가 형성되는 경우, 열간교정기로의 치입이 원활하게 이루어지지 않아 교정작업이 불가능하게 되는 문제점이 있었다. However, the steel sheet produced in the rolling line is smoothly inserted into the hot straightener when the bending part is formed in the vertical direction due to the diameter deviation of the upper and lower rolls for the hot rolling mill, the temperature difference between the upper and lower surfaces of the steel sheet, and the surrounding conditions such as the pass line. There was a problem that can not be done because the correction work.

따라서, 도 1에서와 같이, 열간교정기(100)의 전방측에, 실린더(210)의 작동과정에서 승강되는 압축롤(220)이 구비된 녹다운장치(200)를 설치하여, 가이드빔 (230)에 의해 안내되는 강판의 벤딩부(B)를 하부방향으로 압축한 상태에서, 열간교정기(100)내로 치입시키는 방법이 사용된다. Therefore, as shown in Figure 1, on the front side of the hot calibrator 100, by installing a knock down device 200 is provided with a compression roll 220 is elevated in the operation of the cylinder 210, the guide beam 230 In the state in which the bending portion B of the steel sheet guided by the step is compressed in the downward direction, a method of inserting into the hot straightener 100 is used.

그런데, 녹다운장치(200)의 압축롤(220)과 가이드빔(230)을 사용하여 강판의 벤딩부(B)를 눌러주는 과정에서 벤딩부의 꺽임현상을 발생시키게 뿐만 아니라, 강판의 통판과정에서 마찰로 인하여 긁힌흠이 발생되는 경우 강판의 최종품질을 저하시키게 되는 문제점이 있었다. By the way, using the compression roll 220 and the guide beam 230 of the knock-down apparatus 200 not only causes the bending part of the bending part in the process of pressing the bending portion (B) of the steel sheet, but also friction in the plate process of the steel sheet When scratches are generated due to the problem of lowering the final quality of the steel sheet.                         

또한, 녹다운장치(200)의 조작에 따른 작업시간이 과다하게 소요되어 강판교정에 필요한 온도의 하락을 가져와 평탄도가 저하됨은 물론 유지에 따른 비용이 증대될 뿐만 아니라, 녹다운장치(200)의 부피가 커서 열간압연기와 열간교정기의 사이공간에 설치하기 매우 어려운 문제점이 있었다. In addition, the operation time according to the operation of the knockdown device 200 is excessively excessive, resulting in a drop in temperature required for steel plate calibration, resulting in a decrease in flatness as well as an increase in maintenance costs, and a volume of the knockdown device 200. Because of the large size, there was a problem that is very difficult to install in the space between the hot rolling mill and the hot calibrator.

또한, 녹다운장치(200)의 설치가 불가능한 경우, 열간교정기(100)의 설치방향으로 향하는 강판이 벤딩되지 않도록, 강판의 압연패스 수를 증대시키므로, 압연피치의 지연으로 인해 압연생산성이 저하됨은 물론, 강판의 온도하락으로 인해 품질저하와 원가상승을 가져오는 문제점이 있었다.In addition, when the installation of the knockdown device 200 is impossible, the number of rolling passes of the steel sheet is increased so that the steel sheet facing the installation direction of the hot calibrator 100 is not bent, so that the rolling productivity is deteriorated due to the delay of the rolling pitch. Due to the temperature drop of the steel sheet, there was a problem of quality deterioration and cost increase.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 열간교정기의 작동구조를 변형시키지 않은 상태에서 강판의 벤딩부를 밀면서 눌러서 열간교정기로 치입시킬 수 있도록 된 벤딩강판의 자동 유도 장치를 제공하는 데에 그 목적이 있다. Accordingly, the present invention has been made in order to solve the problems described above, the automatic induction apparatus of the bending steel sheet that can be pressed into the hot straightener while pressing the bending part of the steel sheet without deforming the operation structure of the hot straightener. The purpose is to provide.

The present invention for achieving the above object, the lifting unit for rotating the drive pinion and the driven pin pin coupled to the side of the front frame in the lifting process of the drive rack mounted to the front end of the upper roll housing; A support part which is mounted on the front part of the front frame and receives power through a support frame having a sliding hole in which a driven rack which is engaged with the driven pinion is elevated; An operation part which is pin-coupled to the side part of the driven rack to adjust the height during the operation of the cylinder and press the bending part of the steel plate by using an operation arm equipped with a pressing roll in a horizontal direction at the front end thereof; It consists of a controller that receives the number of light-emitting devices and the light-receiving unit mounted on the support frame and outputs an operation signal to the cylinder, and receives a signal of the limit switch mounted on the driven rack to limit the upper limit of the operation arm.

It is characterized by consisting of a control unit for receiving the input signal to the cylinder 31 to return.                     

먼저, 본 발명에 따른 열간교정기(100)의 전방프레임(110,120)과 후방프레임 (130,140)과 지지빔(150)과 상부롤하우징(160)은 종래기술과 기능상 동일하므로 자세한 설명은 생략하고, 다만 열간교정기(100)의 전방측에 강판유도장치(1)가 장착된 것에 그 차이점이 포함됨을 첨언한다. First, the front frame (110, 120) and rear frame (130, 140) and the support beam 150 and the upper roll housing 160 of the hot calibrator 100 according to the present invention is the same as in the prior art and detailed description thereof will be omitted, but It is added that the difference is included in that the steel plate induction apparatus 1 is mounted on the front side of the hot calibrator 100.

그리고, 승강부(10)는, 열간교정기(100)에 치입되는 강판의 두께에 해당하는 만큼 강판유도장치(1)를 승강시키는 장치로서, 상부롤하우징(160)의 선단부에 수직방향으로 보울트결합된 구동랙(13)과, 전방프레임(110,120)의 측면부에 핀을 통해 결합된 구동피니언(11)과 피동피니언(12)으로 구성된다. In addition, the elevating unit 10 is a device for elevating the steel sheet induction apparatus 1 by the thickness corresponding to the thickness of the steel sheet inserted into the hot straightener 100, and bolt-bonded in the vertical direction to the distal end of the upper roll housing 160. The drive rack 13 and the drive pinion 11 and the driven pinion 12 are coupled to the side portions of the front frame 110, 120 through the pin.

물론, 구동랙(13)의 전방측을 이루는 기어열에 구동피니언(11)의 둘레면에 형성된 기어열이 결합되면서, 구동피니언(11)의 기어열에 피동피니언(12)의 둘레면에 형성된 기어열이 결합되어, 구동피니언(11)의 승강량에 해당하는 만큼 피동피니언(12)이 정역회전을 반복하게 된다. Of course, the gear train formed on the circumferential surface of the drive pinion 11 is coupled to the gear train that forms the front side of the drive rack 13, and the gear train formed on the circumferential surface of the driven pinion 12 to the gear train of the drive pinion 11. The combination is such that the driven pinion 12 repeats the forward and reverse rotations corresponding to the lifting amount of the drive pinion 11.

그리고, 지지부(20)는, 승강부(10)의 승강량에 해당하는 만큼 작동부(30)를 승강시키는 장치로서, 전방프레임(110,120)의 전면부에 장착됨과 더불어 몸체측면에 슬라이딩공(22a)이 형성된 지지프레임(22)과, 지지프레임의 슬라이딩공(22a)에 승강가능하게 삽입된 피동랙(21)으로 구성된다. In addition, the support unit 20 is a device for elevating the operating unit 30 as much as the lifting amount of the elevating unit 10, is mounted on the front portion of the front frame (110, 120) and sliding holes 22a on the body side surface. ) Is formed of a supporting frame 22 and a driven rack 21 inserted into the sliding hole 22a of the supporting frame to be elevated.

물론, 피동랙(21)은, 지지프레임(22)의 슬라이딩공(22a)내에 삽입된 상태에서, 구동랙(13)의 기어열에 결합되는 구동피니언(11)과 피동피니언(12)의 회전과정에서 승강을 반복하면서, 이후에 설명하게 되는 작동부(30)를 강판의 두께에 해당하는 높이로 승하강시키는 기능을 수행한다. Of course, the driven rack 21, in the state of being inserted into the sliding hole 22a of the support frame 22, the rotation process of the drive pinion 11 and the driven pinion 12 coupled to the gear train of the drive rack 13 While repeating the elevating, it performs a function of elevating the operation unit 30 to be described later to a height corresponding to the thickness of the steel sheet.                     

그리고, 작동부(30)는, 지지부(20)에 의해 강판의 두께에 해당하는 높이로 승강함은 물론 제어부의 의해 강판의 벤딩부(B)를 눌러주는 장치로서, 피동랙(21)의 측면부에 핀결합됨은 물론 그 선단부에 누름롤(32)이 장착된 작동암(33)과, 지지빔(150)에 힌지식으로 결합된 상태에서 그 선단부가 작동암(33)의 측부에 핀결합되는 실린더(31)로 구성되어 있다. In addition, the operation part 30 is a device that not only elevates and lowers the height corresponding to the thickness of the steel plate by the support part 20, but also presses the bending part B of the steel plate by the control part, and the side part of the driven rack 21. In addition to the pin coupled to the operating arm 33, the pressing roll 32 is mounted to the front end thereof, and the tip is pinned to the side of the operating arm 33 in a hinged manner to the support beam 150 The cylinder 31 is comprised.

그리고, 제어부는, 강판의 벤딩부(B)에 따라 실린더(31)의 작동여부를 결정하는 제어장치로서, 지지프레임(22)의 전면하부측에 장착되어 벤딩부(B)를 감지하는 발광부(41) 및 수광부(42)와, 피동랙(21)의 측부에 장착되어 작동암(33)의 상한을 감지하는 리미트스위치(43)로 구성되어 있다. The control unit is a control device for determining whether the cylinder 31 is operated according to the bending part B of the steel plate, and is mounted on the front lower side of the support frame 22 to detect the bending part B. And a limit switch 43 mounted on the side of the driven rack 21 to sense an upper limit of the operating arm 33.

이하, 본 발명에 따른 작용을 첨부된 예시도면을 참고로하여 상세하게 설명하면 다음과 같다. Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

먼저, 작업자가 열간압연된 강판의 두께에 해당하는 높이로 열간교정기(100)의 상부롤하우징(160)을 상하향시키면, 상부롤하우징(160)의 선단부에 장착되어 있던 구동랙(13)이 상하향되므로, 구동랙(13)에 기어맞물림식으로 결합되어 있던 구동피니언(11)과 피동피니언(12)이 회전된다. First, when the operator moves the upper roll housing 160 of the hot straightener 100 up and down to a height corresponding to the thickness of the hot rolled steel sheet, the drive rack 13 mounted on the front end of the upper roll housing 160 is moved up and down. Therefore, the drive pinion 11 and the driven pinion 12, which are gear-engaged with the drive rack 13, are rotated.

이때, 지지프레임(22)의 슬라이딩공(22a)에 삽입된 상태에서 피동피니언(12)과 기어맞물림식으로 결합되어 있던 피동랙(21)이 구동랙(13)의 상하향량에 해당하는 만큼 승강되고, 동시에 피동피니언(12)의 측부에 핀을 통해 연결되어있던 작동암(33)이 힌지점(P)을 중심으로 승강되므로, 작동암(33)의 선단부에 장착되어있던 누름롤(32)이 높이조절된다. At this time, the driven rack 21 which is coupled to the driven pinion 12 in gear engagement with the driven pin 22 in the state of being inserted into the sliding hole 22a of the support frame 22 is moved up and down by the amount corresponding to the up and down amount of the driving rack 13. At the same time, since the operating arm 33, which is connected to the side of the driven pinion 12 via a pin, is raised and lowered about the hinge point P, the push roll 32 mounted to the front end of the operating arm 33 is rotated. This height is adjusted.                     

한편, 강판유도장치(1)에 유도되어진 강판의 선단부에 벤딩부(B)가 형성되어, 예컨대 수광부(42)가 발광부(41)로부터 발사되는 레이져빔을 감지하는 못하는 경우, 제어부에서는 실린더(31)의 로드로 리턴신호를 출력하므로, 작동암(33)의 선단부에 장착되어 있던 누름롤(32)이 하향된다.On the other hand, when the bending portion B is formed at the tip end of the steel sheet guided to the steel plate guide device 1, for example, the light receiving portion 42 does not detect the laser beam emitted from the light emitting portion 41, the control unit in the cylinder ( Since the return signal is output to the load of 31), the push roll 32 attached to the tip end of the operation arm 33 is lowered.

이때, 작동암(33)이 하향되는 과정에서, 누름롤(32)이 강판의 벤딩부(B)를 펴주면서 열간교정기(100)의 입구측으로 유도시킨다.At this time, in the process of the operation arm 33 is downward, the pressing roll 32 is guided to the inlet side of the hot calibrator 100 while extending the bending portion (B) of the steel sheet.

만일, 작동암(33)이 승상하는 과정에서 리미트스위치(43)로 접촉되면, 제어부에서는 실린더(31)의 로드로 리턴신호를 출력하고, 이로인해 실린더(31)의 로드가 원상태로 복귀되면서 작동암(33)을 세팅상태로 위치시키는 것이다. If the operating arm 33 is in contact with the limit switch 43 in the process of lifting, the control unit outputs a return signal to the rod of the cylinder 31, thereby operating the rod of the cylinder 31 to its original state. Positioning the arm 33 in the setting state.

이상에서 설명한 바와 같이 본 발명에 따른 벤딩강판의 자동 유도 장치에 의하면, 강판유도장치가 강판의 두께에 해당하는 높이로 승강됨은 물론 강판의 벤딩부를 당기면서 펴준 상태로 열간교정기에 치입시키므로, 강판 벤딩부의 꺽임현상이 미연에 방지됨은 물론 표면흠의 발생이 최소화되어 강판의 표면품질이 향상되는 효과가 있는 것이다.As described above, according to the automatic induction apparatus of the bending steel sheet according to the present invention, the steel sheet induction apparatus is elevated to a height corresponding to the thickness of the steel sheet, as well as pulled into the hot straightener while pulling the bending portion of the steel sheet, thus bending the steel sheet Negative bending is prevented in advance and the occurrence of surface defects is minimized, thereby improving the surface quality of the steel sheet.

또한, 강판유도장치의 설비가 단순화되면서도 부피가 작아지므로 주변기기와의 간섭됨이 없이 설치 및 분리가 가능함은 물론 유지보수에 따른 제반부대비용이 절감되며, 열간교정기로 치입하기 위한 일련의 작업공정이 단순화되므로 압연생산성이 향상되는 효과가 있는 것이다. In addition, as the equipment of the steel plate induction device is simplified and the volume is small, it can be installed and removed without interfering with peripheral devices, and the overall cost of maintenance is reduced, and a series of work processes to be introduced into the hot calibrator Since it is simplified, the rolling productivity is improved.
