Description
본 고안은 연마롤의 편심방지장치에 관한 것으로, 특히 연마기에 장착되어 저석롤에 의해 연마되는 연마롤의 랜드부를 지지하여 롤의 편심을 방지하는 연마롤의 편심방지장치에 관한 것이다.The present invention relates to an apparatus for preventing eccentricity of a polishing roll, and more particularly, to an apparatus for preventing eccentricity of a polishing roll mounted on a polishing machine to support land portions of the polishing roll to be polished by a low stone roll.
일반적으로, 제철소의 각공정에서 사용되는 압연롤은 압연작업 후 마모 및 피로층 제거를 위해 연마작업을 반복적으로 실시하게 된다.In general, the rolling rolls used in each step of the steel mill are repeatedly performed to remove the wear layer and the fatigue layer after the rolling operation.
이때, 롤연마작업은 도1에 도시한 바와같이 연마롤(3)을 연마기(1)에 설치한 후, 저석롤(2)과 동일방향으로 연마롤(3)을 회전시키면서 연마롤의 롤표면을 연마하게 된다.At this time, in the roll polishing operation, as shown in FIG. 1, after the polishing roll 3 is installed in the polishing machine 1, the roll surface of the polishing roll is rotated while rotating the polishing roll 3 in the same direction as the low stone roll 2. Will be polished.
여기서, 연마롤(3)의 양측에 위치하는 롤랜드부(4)를 보조목(7)이 저석롤(2)측으로 밀어 지지함으로써 연마롤이 저석롤에 의해 밀리면서 편심회전되는 현상을 방지하게 된다.Here, the secondary wood 7 is pushed to the low stone roll 2 side to support the roland portions 4 located on both sides of the polishing roll 3 to prevent the polishing roll from being eccentrically rotated by the low stone roll. .
그러나, 종래의 보조목(7)은 몸체(5)에 내장된 실린더(6)에 의해 전진되어 연마롤(3)의 랜드부(4)에 일정압력으로 압착됨으로써 회전되는 롤랜드부와의 마찰에 의해 마모가 심하게 일어난다.However, the conventional auxiliary wood 7 is advanced by the cylinder 6 embedded in the body 5 and is subjected to friction with the roland portion which is rotated by being pressed against the land portion 4 of the polishing roll 3 at a constant pressure. Abrasion occurs badly.
더욱이, 종래의 보조목(7)에는 롤랜드부(4)와의 마찰에 의한 마찰열로 과열되는 현상을 막기 위해 냉각수라인(8)을 통해 그 내부에 냉각수가 공급되지만 냉각효과가 미미하다.Furthermore, in order to prevent the conventional auxiliary wood 7 from being overheated by frictional heat due to friction with the Roland part 4, the cooling water is supplied through the cooling water line 8, but the cooling effect is insignificant.
따라서, 보조목(7)에 의한 연마롤(3)의 편심방지기능이 제대로 발휘되지 못하여 여전히 연마롤의 진원도가 불량되고, 편심회전에 의해 연마롤의 표면에 연마자국이 남게되어 압연제품의 품질을 저하시키는 등의 문제점을 유발시키고 있다.Therefore, the eccentricity prevention function of the polishing roll 3 by the auxiliary wood 7 is not properly exhibited, and the roundness of the polishing roll is still poor, and polishing marks remain on the surface of the polishing roll due to the eccentric rotation, so that the quality of the rolled product is reduced. It is causing problems such as lowering.
본 고안은 연마기에 장착되어 저석롤에 의해 연마되는 연마롤의 랜드부를 롤러를 이용하여 지지케함으로써 연마롤의 편심방지효과를 극대화할 수 있는 연마롤의 편심방지장치를 제공함에 그 목적이 있다.The object of the present invention is to provide an eccentricity prevention device of a polishing roll which can maximize the eccentricity prevention effect of the polishing roll by supporting the land portion of the polishing roll mounted on the polishing machine by a low stone roll using a roller.

연마기(1)의 컬럼(1-1) 양외측에 고정 부착되는 몸체(5)에는 실린더(6)가 내장되어 있고, 다시 이 실린더(6)의 로드선단에는 연결브래킷(7)이 볼트에 의해 고정 결합되어 있으며, 연결브래킷(7)의 중심홀(7-1)에는 롤하우징(8)이 중심핀(9)을 중심으로 회전되도록 결합되어 있다.The cylinder 6 is built in the body 5 fixedly attached to both sides of the column 1-1 of the grinding machine 1, and the connecting bracket 7 is connected to the rod end of the cylinder 6 by bolts. It is fixedly coupled, the roll housing 8 is coupled to the center hole (7-1) of the connecting bracket (7) so as to rotate around the center pin (9).
이때, 중심핀(9)에는 그 일단측에 와셔(10)가 끼워진 후, 그 핀홀(9-1)에 분할핀(11)이 삽입되어 이탈을 방지하게 되고, 그 내부에 오일공급라인(9-2)이 형성되어 마찰이 발생하는 접촉개소의 윤활을 위해 오일을 공급하게 된다.At this time, after the washer 10 is inserted into one end side of the center pin 9, the split pin 11 is inserted into the pin hole 9-1 to prevent separation, and the oil supply line 9-9 is inserted therein. 2) is formed to supply oil for lubrication of the contact point where friction occurs.
그리고, 롤하우징(8)에는 그 상하부에 각각 상하부롤러(12,13)가 베어링(17)에 의해 롤러핀(14,15)을 중심으로 회전되도록 결합되어 있고, 롤러핀(14,15)에는 베어링(17)의 축방향 유동을 방지하기 위해 부시(20)가 끼워지면서 롤하우징(8)으로부터의 이탈을 방지하기 위하여 그 일단에 각각 와셔(21)와 2개의 너트(22)가 차례로 결합되어진다.The upper and lower rollers 12 and 13 are coupled to the roll housing 8 so as to be rotated about the roller pins 14 and 15 by the bearing 17, respectively, and to the roller pins 14 and 15, respectively. In order to prevent axial flow of the bearing 17, the bush 20 is fitted and the washers 21 and the two nuts 22 are respectively coupled to one end thereof in order to prevent separation from the roll housing 8. Lose.
여기서, 롤러핀(14,15)에는 각각 베어링(17)의 양외측에 위치하도록 오일실(Oil Seal)(19)이 끼워지게 되고, 이 오일실은 베어링의 윤활을 위해 공급되는 오일을 실링(Sealing)하게 된다.Here, the oil seal (19) is fitted to the roller pins (14, 15) so as to be located on both sides of the bearing (17), respectively, this oil seal seals the oil supplied for lubrication of the bearing (Sealing) )
또한, 롤러핀(14,15)에는 각각 그 내부에 오일공급라인(14-1,15-1)이 형성되어 있어 윤활용 오일을 베어링(17)에 공급하게 되고, 베어링에 공급된 오일은 오일실(19)에 의해 실링이 이루지게 된다.In addition, the roller pins 14 and 15 have oil supply lines 14-1 and 15-1 formed therein, respectively, to supply lubricating oil to the bearings 17, and the oil supplied to the bearings is an oil seal. The sealing is achieved by (19).
한편, 롤러핀(14,15)과 중심핀(9)의 내부에 각각 형성되는 오일공급라인(14-1,15-1,9-2)에는 그 입구에 니플(16)이 결합되어 있어 이를 통해 오일을 공급하게 된다.Meanwhile, the nipples 16 are coupled to the inlets of the oil supply lines 14-1, 15-1, and 9-2 formed in the roller pins 14 and 15 and the center pin 9, respectively. Supply oil.
이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
연마기(1)에 연마롤(3)이 장착되면 실린더(6)를 작동시켜 롤하우징(8)을 전진시키게 되고, 상하부롤(12,13)이 연마롤(3)의 양측 랜드부(4)에 일정압력으로 압착되면 실린더(6)의 전진작동이 멈추게 된다.When the polishing roll 3 is mounted on the polishing machine 1, the cylinder 6 is operated to advance the roll housing 8, and the upper and lower rolls 12 and 13 are land portions 4 on both sides of the polishing roll 3. When pressed at a constant pressure in the forward movement of the cylinder (6) is stopped.
그리고, 저석롤(2)에 의해 연마롤(3)이 연마되기 시작하면 상하부롤(12,13)은 롤랜드부(4)를 일정압력으로 지지한 상태에서 구동이 이루어진다.Then, when the polishing roll 3 begins to be polished by the low stone roll 2, the upper and lower rolls 12 and 13 are driven in a state in which the roland portion 4 is supported at a constant pressure.
이때, 상하부롤(12,13)은 롤랜드부(4)와 함께 회전이 이루어지기 때문에 종래와 같은 마찰열이 발생되지 않을 뿐만아니라 마찰에 따른 마모도 발생되지 않으며, 이에 따라 처음 설정된 압력으로 롤랜드부를 지지함으로써 연마롤(3)의 편심을 완벽하게 방지하게 된다.At this time, since the upper and lower rolls 12 and 13 are rotated together with the roland portion 4, not only the frictional heat as in the related art is generated but also the abrasion caused by the friction is not generated. Eccentricity of the polishing roll 3 is completely prevented.
본 고안은 연마롤의 랜드부를 마모나 마찰열없이 처음 설정된 압력으로 지지함으로써 연마롤의 편심회전을 방지하고, 이로부터 연마롤의 진원도와 원통도를 향상시키면서 더 나아가 압연제품의 품질 및 작업의 생산성을 높일 수 있는 효과를 제공하게 된다.The present invention prevents the eccentric rotation of the polishing roll by supporting the land portion of the polishing roll at a pressure set for the first time without abrasion or frictional heat, thereby improving the roundness and cylindricality of the polishing roll and further improving the quality of the rolled product and the productivity of the work. It can provide a boosting effect.
