본 발명은 사상압연기용 입구가이드의 가이드롤러를 윤활하여주는 오일공급장치에 관한 것으로, 특히 오일공급장치의 작동과정에서 생성되는 오일을 가이드롤러의 베어링을 향해 분무상태로 공급시킬 수 있도록 된 사상압연기용 입구가이드롤러의 오일 공급 장치에 관한 것이다. The present invention relates to an oil supply device for lubricating a guide roller of an inlet guide for a finishing mill. In particular, the finishing mill is capable of supplying oil generated during the operation of the oil supply device to a bearing of the guide roller in a sprayed state. It relates to an oil supply device of the inlet guide roller.

일반적으로, 가열로에서 가열되어진 소재는 조압연, 중간조압연, 사상압연 등의 과정을 거쳐 냉각설비에서 냉각되어 최종제품으로 생산되는데, 특히 사상압연기의 입측을 이루는 입구가이드에 소재의 진행속도와 동일하게 회전하면서 소재를 사상압연롤로 치입하여주는 가이드롤러가 설치되어 있다. In general, the material heated in the furnace is produced in the final product by cooling in a cooling facility through rough rolling, intermediate rough rolling, filament rolling, etc., in particular, the speed of the material in the inlet guide forming the inlet of the filament rolling mill. The guide roller is installed to feed the material into the finishing roll while rotating in the same way.

이때, 가이드롤러(guide roller)는, 입구가이드의 출측에 베어링을 통해 설치되어 사상압연롤의 압연방향을 향해 압연소재를 안내하는 회전체로서, 예컨대 베어링에 구리스와 같은 윤활수단을 공급하여 가이드롤러의 회전저항을 최소화하므로써 가이드롤러의 수명을 연장시킴이 바람직하다. At this time, the guide roller is a rotating body which is installed through the bearing on the exit side of the inlet guide and guides the rolled material toward the rolling direction of the finishing rolling roll. For example, the guide roller is supplied with lubrication means such as grease to the bearing. It is desirable to extend the life of the guide roller by minimizing the rolling resistance of the roller.

그런데, 가이드롤러의 회전속도는 대략 5.000∼50.000rpm을 유지하는 상태이므로, 가이드롤러의 베어링으로 구리스와 같은 윤활수단을 급지하는 작업과정이 매우 어려움은 물론, 구리스의 급지과정에서 회전부하의 증가로 인해 베어링이 손상되어 수명을 단축시키게 되는 문제점이 있었다. However, since the rotational speed of the guide roller is maintained at about 5.000 to 50.000 rpm, the process of feeding the lubrication means such as grease into the bearing of the guide roller is very difficult, and of course, the rotational load increases during the feeding of the grease. There was a problem that the bearing is damaged due to shortening the life.                         

더욱이, 가이드롤러의 베어링이 손상되어, 사상압연롤로 안내되던 압연소재의 접촉면에 긁힌흠과 같은 불량을 발생시키는 경우, 사상압연기의 압연작업을 중단하고 가이드롤의 교체작업을 수행해야하므로 작업하중 및 부대경비가 증대될 뿐만 아니라, 소재의 생산성이 저하되는 문제점이 있었다. In addition, when the bearing of the guide roller is damaged and causes defects such as scratches on the contact surface of the rolled material guided by the finishing roll, the rolling work of the finishing mill must be stopped and the replacement of the guide roll must be performed. In addition to increased incidental expenses, there was a problem that the productivity of the material is lowered.

그리고, 가이드롤러의 베어링을 구리스로 급지하는 과정에서, 예컨대 베어링에 압연소재의 스케일이나 냉각수와 같은 비산물질들이 침투되는 경우, 베어링이 손상되어 회전불량을 발생시키므로, 가이드롤러에 의해 사상압연롤로 안내되는 소재의 표면품질을 저하시키는 문제점이 있었다.In the process of feeding the bearings of the guide rollers with grease, for example, when scattering materials such as scales or cooling water of the rolled material penetrate the bearings, the bearings are damaged and rotational defects are generated. There was a problem of lowering the surface quality of the material.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 오일공급장치의 작동과정에서 생성되는 오일을 가이드롤러의 베어링을 향해 분무상태로 공급하여 베어링의 수명을 연장시킬 수 있도록 된 사상압연기용 입구가이드롤러의 오일 공급 장치를 제공하는 데에 그 목적이 있다. Therefore, the present invention has been made in order to solve the problems described above, it is possible to extend the life of the bearing by supplying the oil generated during the operation of the oil supply device sprayed toward the bearing of the guide roller It is an object of the present invention to provide an oil supply device for an inlet guide roller for a finishing mill.

An oil line for supplying oil from the tank to the oil receiving part and an air line for supplying air from the air tank to the oil receiving part during the operation of the air compressor are formed, and the oil line is advanced through the elastic force of the elastic spring in the oil receiving part. In addition to returning through the oil pressure of the piston is formed on the circumferential surface of the first and second oil grooves, while guide the oil in the oil grooves through the air hose using the pneumatic pressure of the air line on the piston movement path A spray line is formed to inject the oil supply port of the roller, and outputs an operation signal to the pump motor during the set time of the timer to the oil pump.

그리고, 제어부(60)는, 펌프모우터(61)에 전기적으로 연결되어 오일펌프(21)로 작동신호를 출력하는 스위칭수단으로서, 그 내부회로에 펌프모우터(61)로 설정시간동안 작동신호를 출력하는 타이머가 내장되어 있다. The control unit 60 is a switching means electrically connected to the pump motor 61 and outputting an operation signal to the oil pump 21. The operation signal is supplied to the internal circuit of the pump motor 61 for a predetermined time. There is a built-in timer that outputs.

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, 가이드롤러(120)의 베어링(140)에 윤활오일을 공급하기 위해서, 오일공급장치(1)의 제어부(60)를 작동시키면, 제어부(60)의 타이머에 설정된 시간동안 펌프모우터(61)가 가동되므로, 오일펌프(21)가 작동된다. First, when the control unit 60 of the oil supply device 1 is operated to supply lubricating oil to the bearing 140 of the guide roller 120, the pump motor 61 for a time set by the timer of the control unit 60. Is operated, the oil pump 21 is operated.

이렇게 하면, 오일탱크(미도시)에 충진되어있던 오일이 오일펌프(21)의 작동과정에서 피스톤커버(11)의 오일홈(11a)과 배출구(11b)을 경유하여 오일수용부 (10)의 제2공간부(10b) 또는 오일라인(20)으로 압송된다. In this way, the oil filled in the oil tank (not shown) of the oil receiving portion 10 via the oil groove 11a and the outlet 11b of the piston cover 11 during the operation of the oil pump 21. It is pumped to the second space portion 10b or the oil line 20.

물론, 펌프모우터(61)의 작동과 동시에 공기압축기(31)도 작동되므로, 공기탱크(미도시)의 공기가 공기라인(30)을 통해 오일수용부(10)로 압송된다. Of course, since the air compressor 31 is also operated at the same time as the operation of the pump motor 61, the air of the air tank (not shown) is pumped to the oil receiving portion 10 through the air line (30).

이때, 피스톤(40)은 오일수용부(10)에 내장되어 탄성스프링(41)에 의해 제2공간(10b)에 위치하고 있는 상태이므로, 피스톤(40)의 둘레면을 이루는 제1,2오일홈(42,43)에 오일이 충만된다. At this time, since the piston 40 is in the oil receiving portion 10 and is positioned in the second space 10b by the elastic spring 41, the first and second oil grooves forming the circumferential surface of the piston 40 are provided. (42,43) is filled with oil.                     

이어서, 오일수용부(10)의 제2공간부(10b)에 오일이 점차적으로 충진되는 과정에서, 제2공간부(10b)내의 오일압(20∼30㎏/㎠)이 탄성스프링(41)의 탄성력을 이기는 경우, 피스톤(40)이 스프링커버(12)의 방향으로 이동된다. Subsequently, in the process of gradually filling oil in the second space portion 10b of the oil receiving portion 10, the oil pressure (20 to 30 kg / cm 2) in the second space portion 10b is elastic spring 41. When winning the elastic force of the piston 40 is moved in the direction of the spring cover 12.

물론, 피스톤(40)이 스프링커버(12)의 방향으로 이동하는 과정에서, 피스톤 (40)의 오일홈(42,43)에 충만되어있던 오일이 오일수용부(10)의 제3공간부(10c)를 향해 이동되는 것이다. Of course, in the process of moving the piston 40 in the direction of the spring cover 12, the oil filled in the oil grooves 42 and 43 of the piston 40 is the third space portion ( 10c).

만일, 피스톤(40)이 스프링커버(12)의 방향으로 이동하는 과정에서, 예컨대 제2오일홈(43)이 분사라인(50)과 일치되는 경우, 공기라인(30)에서 압송되는 공기가 자체압력(2∼3㎏/㎠)에 의해 제2오일홈(43)으로 압송된다.If the piston 40 moves in the direction of the spring cover 12, for example, when the second oil groove 43 coincides with the injection line 50, the air being compressed in the air line 30 is itself. By the pressure (2-3 kg / cm <2>), it pushes into the 2nd oil groove 43. As shown in FIG.

물론, 공기라인(30)의 압송공기가 제2오일홈(43)과 분사라인(50)을 통해 외부로 배출되려고 하는 상태가 된다.Of course, the compressed air of the air line 30 is to be discharged to the outside through the second oil groove 43 and the injection line 50.

물론, 제2오일홈(43)내에 충만되어있던 오일이 공기라인(30)의 공압에 의해 분사라인(50)을 통해 외부로 배출되면서, 공기호스(51)를 매개로 급유구(125)를 경유하여 가이드롤러(120)의 베어링(140)에 자동으로 공급되는 것이다.Of course, the oil filled in the second oil groove 43 is discharged to the outside through the injection line 50 by the pneumatic pressure of the air line 30, the air supply port 125 through the air hose 51 It is automatically supplied to the bearing 140 of the guide roller 120 via.

이어서, 피스톤(40)이 스프링커버(12)의 방향으로 이동되는 과정에서, 피스톤(40)의 제1오일홈(42)이 분사라인(50)과 일치하는 경우, 제1오일홈(42)에 충만되어있던 오일을 분사라인(50)을 통해 베어링(140)으로 공급된다.Subsequently, when the piston 40 is moved in the direction of the spring cover 12, when the first oil groove 42 of the piston 40 coincides with the injection line 50, the first oil groove 42 Oil, which was filled in, is supplied to the bearing 140 through the spray line 50.

물론, 피스톤(40)의 제1오일홈(42)과 분사라인(50)이 일치하는 경우, 오일라인(20)과 제2오일홈(43)이 상호 일치되므로, 오일라인(20)내의 오일이 다시 제2오일홈(43)으로 충만되는 것이다. Of course, when the first oil groove 42 and the injection line 50 of the piston 40 coincide, since the oil line 20 and the second oil groove 43 coincide with each other, the oil in the oil line 20 This is filled with the second oil groove 43 again.                     

이로 인해, 공기압축기(31)의 작동에 의해 공기라인(30)으로 공기가 압송되는 경우 라면, 피스톤(40)이 탄성스프링(41)에 의해 피스톤커버(11)의 방향으로 이동하는 과정에서도, 제2오일홈(43)에 충만되어있던 오일이 분사라인(50)을 통해 베어링(140)으로 분사되는 것을 의미하는 것이다.Therefore, in the case where the air is compressed to the air line 30 by the operation of the air compressor 31, even in the process of moving the piston 40 in the direction of the piston cover 11 by the elastic spring 41, This means that the oil filled in the second oil groove 43 is injected into the bearing 140 through the spray line 50.

따라서, 제어부(60)에 내장된 타이머의 시간을 조정하여 펌프모우터(61)의 기동과 정지시간을 반복적으로 행하면서, 오일탱크로부터 공급되는 오일을 공압을 통해 분무화하여 가이드롤러(120)의 베어링(140)을 윤활하므로써, 가이드롤러의 작동효율이 증대되는 것이다.Accordingly, while adjusting the time of the timer built in the control unit 60 to repeatedly start and stop the pump motor 61, the oil supplied from the oil tank is atomized through pneumatic guide rollers 120. By lubricating the bearing 140, the operating efficiency of the guide roller is increased.

이상에서 설명한 바와 같이 본 발명에 따른 사상압연기용 입구가이드롤러의 오일공급장치에 의하면, 제어부에 내장된 타이머의 작동시간을 적절하게 조정하여 펌프모우터의 기동과 정지시간을 반복적으로 행하면서 가이드롤러의 베어링을 향해 분무상태의 오일을 자동으로 공급하므로써, 가이드롤러의 베어링의 조기손상이 방지되어 수명이 연장됨은 물론 가이드롤러의 유지보수에 따른 제반부대비용이 절감되는 효과가 있는 것이다.As described above, according to the oil supply device of the inlet guide roller for the finishing mill according to the present invention, the guide roller is repeatedly operated to start and stop the pump motor by appropriately adjusting the operation time of the timer built in the controller. By automatically supplying the sprayed oil toward the bearing of the bearing, the premature damage of the bearing of the guide roller is prevented, and the life span is extended, and the cost of all the accompanying maintenance of the guide roller is reduced.

또한, 오일공급장치의 작동과정에서 윤활오일이 직접 가이드롤러의 베어링으로 공급되므로써, 가이드롤러의 베어링으로 압연소재의 스케일이나 냉각수와 같은 비산물질들의 침투가 방지되어 베어링의 수명이 연장됨은 물론, 이로인해 사상압연롤로 안내되는 소재의 표면품질이 일정하게 유지되어 제품의 생산단가가 절감되는 효과가 있는 것이다. In addition, since the lubricating oil is directly supplied to the bearing of the guide roller during the operation of the oil supply device, the penetration of the scattering materials such as the scale of the rolled material and the cooling water is prevented from extending into the bearing of the guide roller, thereby extending the life of the bearing. Due to this, the surface quality of the material guided by the finishing roll is kept constant, thereby reducing the production cost of the product.
