(11-4) coincides with the center.
여기서, 실린더(11-12)를 후진시키면서 실린더(11-8)를 전진시키게 되면 조인트(5)가 커플링(4)의 선단에 끼워지게 되고, 다시 실린더(11-12)를 전진시키면 작동대(11-13)에 의해 후진되어 있던 헤더(11-5)가 전진되면서 체결볼(11-6)을 이용하여 조인트(5)를 고정시키게 된다.Here, when the cylinder 11-8 is advanced while reversing the cylinder 11-12, the joint 5 is fitted to the tip of the coupling 4, and when the cylinder 11-12 is advanced again, the operating table As the header 11-5, which has been reversed by 11-13, is advanced, the joint 5 is fixed using the fastening ball 11-6.
이와같이 조인트(5)와 커플링(11-4)이 결합되면 제어부(16)의 조작에 따라 그리스라인(11-10)을 통해 그리스가 공급되고, 다시 이 그리스는 삽입구(11-9)를 통해 커플링과 조인트를 거쳐 초크(2)내의 베어링에 급지된다.When the joint 5 and the coupling 11-4 are coupled in this manner, grease is supplied through the grease line 11-10 according to the operation of the control unit 16, and the grease is supplied through the insertion hole 11-9. It is fed to the bearing in the choke 2 via the coupling and the joint.
한편, 모터(9-2)를 작동시켜 스크루(9-3)를 회전시키게 되면 이송블록(9-7)이 스크루를 따라 상하이동을 하게 되고, 이에 따라 분사노즐(9-11)이 초크라이너(2-1)의 상단에 위치하게 된다.On the other hand, when the screw (9-3) is rotated by operating the motor (9-2), the transfer block (9-7) is moved along the screw, so that the injection nozzle (9-11) the chokeliner It is located at the top of (2-1).
이때, 실린더(9-8)를 전진시키어 분사노즐(9-11)을 초크라이너(2-1)에 접근시키게 되고, 그리스라인(9-6)을 통해 그리스를 공급하면 분사노즐로부터 그리스가 분사되면서 초크라이너에 그리스를 도포하게 된다.At this time, the cylinder 9-8 is advanced to bring the injection nozzle 9-11 to the choliner 2-1, and when grease is supplied through the grease line 9-6, grease is injected from the injection nozzle. The grease is then applied to the chokeliner.
그리고, 모터(8-2)를 이용하여 회전커플링(8-5)을 회전시키면서 삽입구(8-4)를 롤단부(3)와 일치시키고, 삽입구와 롤단부가 일치되면 모터를 정지시킨 상태에서 실린더(8-3)를 전진시키어 삽입구를 롤단부에 결합시키게 된다.Then, while the rotary coupling 8-5 is rotated using the motor 8-2, the insertion port 8-4 coincides with the roll end 3, and when the insertion port and the roll end coincide, the motor is stopped. The cylinder (8-3) is advanced to engage the insertion hole in the roll end.
여기서, 다시 모터(8-2)를 구동시키면 롤단부(3)가 회전되면서 롤(1)이 회전하게 된다.When the motor 8-2 is driven again, the roll 1 rotates while the roll end 3 rotates.
이때, 실린더(13-2)를 전진시키게 되면 와이퍼(13-3)가 각각 상하롤(1)의 표면에 밀착되면서 롤의 표면에 부착된 이물질을 제거하게 된다.At this time, when advancing the cylinder 13-2, the wiper 13-3 is in close contact with the surface of the upper and lower rolls 1, respectively, to remove foreign substances attached to the surface of the roll.
또한, 롤(1)의 표면 이물질제거작업이 완료되면 롤단부(3)의 중심이 밀스탠드의 커플링중심과 일치되도록 모터(8-2)를 조정하여 정지시키게 된다.In addition, when the surface foreign matter removing operation of the roll 1 is completed, the motor 8-2 is adjusted to stop so that the center of the roll end portion 3 coincides with the coupling center of the mill stand.
한편, 압연대기롤(1)의 예열작업은 모터(18-4)의 피니언기어(18-3)를 구동시켜 차단셔터(18-2)를 전진시키어 압연대기롤을 외부와 차단시키고, 다시 모터(12-5)의 피니언기어(12-6)를 회전시키어 차단셔터(12-4)를 개방시키게 된다.On the other hand, the preheating operation of the rolling waiting roll 1 drives the pinion gear 18-3 of the motor 18-4 to advance the shut-off shutter 18-2 to block the rolling waiting roll from the outside, and then again the motor. The pinion gear 12-6 of (12-5) is rotated to open the shut-off shutter 12-4.
그리고, 차단셔터(12-4)에 의해 삽입구(12-1)가 개방되면 발열부재(12-7)를 작동시켜 압연대기롤(1)을 예열시키게 된다.When the insertion hole 12-1 is opened by the blocking shutter 12-4, the heat generating member 12-7 is operated to preheat the rolling standby roll 1.
본 고안은 밀스탠드에 투입하기 전 압연대기롤의 초크에 그리스를 급지하고, 휠베어링을 점검하는 동시에 롤표면을 세척하고 초크라이너에 그리스를 도포하면서 롤의 센터링을 조정하는 작업을 수행할 수 있으며, 대기롤을 예열함으로써 작업의 생산성을 높이고, 롤의 손상을 예방할 수 있는 효과를 제공하게 된다.The present invention can perform the operation of adjusting the centering of the roll while feeding grease to the choke of the rolling standby roll, checking the wheel bearing, washing the roll surface and applying grease to the chokeliner before putting it into the mill stand. By preheating the atmospheric roll, the productivity of the work can be increased and the damage of the roll can be prevented.
