Description
본 고안은 지중전선관을 성형할 때에 인출심사인 피복강선을 내부에 삽입하기 위한 성형장치에 관한 것으로, 특히 지중전선관 성형시 지중전선관의 내부에 삽입되는 인출심사인 피복강선을 보다 간단한 공정에 의해 삽입할 수 있도록 하기 위한 것이다.The present invention relates to a molding apparatus for inserting the coated steel wire which is drawn out inside when forming the underground cable, in particular the insertion of the coated steel wire that is inserted into the inside of the underground wire tube when the underground wire tube is formed by a simpler process It is to make it possible.
일반적으로 지중전선관의 내부에 삽입된 인출심사인 피복강선은 지중전선관의 지하매설 작업시에 지중전선관의 내부로 삽입하기 위한 전선을 인출하기 위한 것으로, 지중전선관을 지중에 매설작업할때나 매설작업후에 일측에서 피복강선과 전선을 서로 연결하여 타측에서 끌어당겨줌으로써 전선을 지중전선관에 용이하게 삽입 할 수 있도록 하기 위한 것이다.In general, the coated steel wire, which is a drawing examination inserted into the underground conduit pipe, is used to draw out the wire for insertion into the underground conduit pipe during the underground laying of the underground conduit pipe, and when the underground conduit pipe is buried or buried Afterwards, the coated steel wire and the electric wire are connected to each other and pulled from the other side so that the electric wire can be easily inserted into the underground conduit pipe.
따라서 종래에는 지중전선관의 내부에 인출심사를 삽입하기 위해 개발된 기술이 실용신안공고 제 90-2407로 공고된 것이 있었으나, 이는 지중전선관의 성형시 원료액의 분량이 많이 압출되어 성형관의 두께가 고르지 못한 점을 해소하기 위해 원료액을 고르게 압출되어 나가도록 구성함으로써 성형관의 두께를 일정하게 하기 위한 기술이 주된 것이고, 또한 전선관의 내부에 삽입되는 인출심사에는 피복이 입혀지지 않았기 때문에 매설후 시간의 경과로 녹이 빨리 슬게 되는 단점과 이를 모르고 전선을 인출선과 연결하여 인출하는 도중에 인출심사가 끊어져 버리는 경향이 있어서 전선을 인출하는데에 많은 애로사항이 있었던 것이었다.Therefore, in the related art, the technology developed for inserting the drawing examination inside the underground conduit tube was announced as Utility Model Publication No. 90-2407. However, when the underground conduit tube is formed, the amount of the raw material liquid is extruded so that the thickness of the forming tube is increased. In order to solve the unevenness, the main technique is to make the thickness of the forming pipe uniform by extruding the raw material liquid evenly. Also, since the drawing examination inserted into the conduit is not coated, the time to bury it There was a lot of difficulties in pulling out the wire because the drawer tends to be cut off in the middle of drawing out the wire by connecting it with the leader line without knowing the shortcomings of rusting quickly due to the lapse of time.
그래서 최근에는 지중전선관에 삽입되는 인출심사에 녹이 스는 것을 방지하기 위하여 피복을 입혀 삽입하였다. 상기와 같이 지중전선관에 합성수지로 피복이 된 인출심사를 삽입할때에는 지중전선관을 성형하는 성형롤러의 내부에 높은 온도가 발생하게 되므로 온도차에 의해서 인출심사에 입혀진 피복이 벗겨지게 되어 있었다. 따라서 제품의 질 저하로 인해 소비자 불만이 많이 발생하였기때문에 이를 방지하기 위해서 성형롤러의 내부에 차가운 공기를 주입해 온도를 낮추어 가면서 피복이 된 인출심사를 삽입함으로써 피복이 벗겨지는 것을 방지하였지만 공정상 콤프레셔 등의 설비증가가 필요하게 되기 때문에 경제적이지 못하였던 것이다.Recently, in order to prevent rust in the drawing examination inserted into the underground conduit, it was inserted with a coating. As described above, when inserting the drawn examination coated with synthetic resin into the underground conduit tube, a high temperature is generated inside the forming roller forming the underground conduit tube, so that the coating applied to the drawing examination due to the temperature difference is peeled off. Therefore, in order to prevent this, many consumers were dissatisfied with the deterioration of the product quality.In order to prevent this, the coating was pulled out by inserting the drawn out examination while lowering the temperature by injecting cold air into the inside of the forming roller. It was not economical because it needed to increase equipment.
또한 상기의 성형롤러의 내부에 차가운 공기를 일정하게 주입하여 내부의 온도를 냉각하더라도 주입되는 공기의 압력이 일정하지 않기 때문에 지중전선관의 성형시에 변형이 일어나게 되므로 제품에 대한 불량률이 많이 발생하여 생산성이 떨어지게 되므로 경쟁력이 약하였던 것이다.In addition, even if cold air is constantly injected into the forming roller to cool the inside temperature, the pressure of the injected air is not constant. Therefore, deformation occurs during molding of the underground conduit tube, resulting in a large defect rate of the product. Will fall so competitive was weak.
본 고안은 상기와 같은 결함을 해결하기 위하여 개량 안출한 것으로, 지중전선관의 내부에 피복이 된 인출심사를 삽입할 때, 원료액을 겔상태로 유지하기 위해서 다이스의 외부에 부착한 히터의 가열로 인해 발생하는 뜨거운 열에 의하여 피복이 녹아 벗겨지는 것을 방지하기 위하여, 다이스의 내부에 차가운 공기를 주입하여 온도를 낮추는 대신에, 다이스의 내부에 석면단열재를 삽입형성함으로써 외부에서 발산되는 열을 석면단열재가 간단히 차단하여 내부의 온도를 일정하게 낮출 수 있도록 하고자 함을 목적으로 한 것이다.The present invention has been devised to solve the above-mentioned defects, and when inserting a coated drawing examination inside the underground conduit tube, the heater is attached to the outside of the die to keep the raw material liquid in a gel state. In order to prevent the coating from melting and peeling off due to the hot heat generated, instead of lowering the temperature by injecting cold air into the die, the asbestos heat insulating material is formed by inserting asbestos heat insulating material into the die. It aims to make the internal temperature constant by simply shutting off.
따라서 다이스의 내부에서는 석면단열재에 의해 항상 일정하게 온도를 낮추어 주기 때문에 성형기에서 지중전선관을 성형하더라도 변형이 잘 일어나지 않게 되므로 양질의 제품을 만들 수 있는 것이다.Therefore, since the internal temperature of the die is constantly lowered by the asbestos insulation material, even if the underground conduit is formed in the molding machine, deformation does not occur well, thereby making a good product.

원재료가 공급되는 호퍼(1)와, 상기 호퍼(1)를 거친 원료액이 압출되는 압출기(2)와, 상기 압출기(2)에서 압출된 원료액이 통과하며 지중전선관의 내부로 피복강선을 삽입하기 위한 다이스(3)와, 상기 다이스(3)를 통과한 원료액으로 지중전선관(6)을 성형하는 성형기(4)로 구성되는 지중전선관의 성형장치에 있어서,A hopper 1 through which raw materials are supplied, an extruder 2 through which the raw material liquid passed through the hopper 1 is extruded, and a raw material liquid extruded from the extruder 2 pass through and insert a coated steel wire into the inside of the underground wire tube.

상기 다이스(3)의 내측에 석면 단열재(31)를 형성하여 히이터(32)의 열을 차단하도록 구성한 것을 특징으로 하는 지중전선관의 성형장치를 제공하기 위한 것이다.An asbestos insulation material 31 is formed inside the die 3 to block the heat of the heater 32 to provide a molding apparatus for underground wire tubes.
상기와 같이 구성된 본 고안의 작용효과를 첨부된 도면에 의거하여 보다 구체적으로 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above in more detail based on the accompanying drawings as follows.
도 1의 전체 공정도에 나타내는 바와같이, 지중전선관(6)을 성형하기 위해서는 먼저 호퍼(1)에 지중전선관(6)을 성형하기 위한 원재료를 투입한다. 상기 호퍼(6)로 투입된 원재료는 압출기(2)의 내부에 형성된 스크류(도면에 미도시)를 통해서 다이스(3)로 압출된다. 이때 압출통로에는 히이터(도면에 미도시)가 장착되어 있어 원재료는 열에 의해 녹으면서 겔상태로 이송하게 되는 것이다. 상기와 같이 원료액이 이송된 다이스(3)의 외부표면에도 히이터(32)가 장착되어 있기때문에 열을 받은 원료액은 겔상태를 계속 겔 상태를 유지하면서 다이스(3)와 근접하게 장착된 성형기(4)로 유도되어 지중전선관(6)을 성형하게 된다. 이때 원료액을 성형기(4)로 유도하는 다이스(3)는 외부에 장착된 히이터(32)에 의해서 다이스(3) 내부의 용융온도가 보통 120℃정도로 유지된다.As shown in the overall process diagram of FIG. 1, in order to mold the underground wire tube 6, first, a raw material for molding the underground wire tube 6 is introduced into the hopper 1. The raw material introduced into the hopper 6 is extruded into the die 3 through a screw (not shown) formed inside the extruder 2. At this time, the extrusion passage is equipped with a heater (not shown in the drawing), so that the raw material is melted by heat and transferred to a gel state. Since the heater 32 is also mounted on the outer surface of the die 3 to which the raw material liquid is transferred as described above, the heated raw material liquid is kept in the gel state while being kept in the gel state, and is mounted close to the die 3. Guided to (4) to form the underground conduit (6). At this time, the die 3 for guiding the raw material liquid to the molding machine 4 is maintained at a melting temperature of about 120 ° C. in the die 3 by the heater 32 mounted on the outside.
상기와 같이 다이스(3)를 통과한 원료액이 성형기(4)로 유도될 때 다이스(3)의 내부에 형성된 관통공(33)으로 인출심사인 피복강선(5)을 동시에 주입한다. 이때 다이스(3) 내부의 온도가 상기와 같이 높기 때문에 피복강선(5)을 투입하게 되면 피복(51)이 벗겨지게 된다.As described above, when the raw material liquid having passed through the die 3 is guided to the molding machine 4, the coated steel wire 5 which is drawn out is simultaneously injected into the through hole 33 formed in the die 3. At this time, since the temperature inside the die 3 is high as described above, the coating 51 is peeled off when the coated steel wire 5 is introduced.
그렇지만 본 고안은 이러한 단점을 보완하기 위하여 다이스(3) 내부의 온도를 낮추기 위하여 에어펌프에 의해 차가운 공기를 다이스(3) 내부로 주입하는 대신에, 석면단열재(31)를 원료액이 주입되는 내측으로 형성하고 있기때문에 다이스(3)의 외부에 장착된 히이터(32)에서 발생되는 높은 열은 원료액이 주입되는 다이스(3)의 외주면으로만 전달되지 내부중앙으로까지는 석면단열재(31)가 열을 차단하여 주므로 전달되지 않는다.However, the present invention, instead of injecting the cool air into the die 3 by the air pump in order to lower the temperature inside the die 3 to compensate for this disadvantage, the asbestos insulating material 31 inside the raw material liquid is injected Since the high heat generated from the heater 32 mounted on the outside of the die 3 is transmitted only to the outer circumferential surface of the die 3 into which the raw material liquid is injected, the asbestos insulation material 31 is heated to the inner center. It is not delivered because it blocks.
그래도 미세한 열은 계속해서 내부로 전달되게 되지만 이때 내부의 용융온도는 외측의 120℃ 보다 훨씬 낮은 40℃ 이내로 떨어지게 되는 것이다.The finer heat continues to be transferred to the interior, but the internal melting temperature drops to 40 ° C, much lower than 120 ° C outside.
상기와 같이 본 고안은 다이스(3)의 내부에 형성된 석면단열재(31)에 의해 내부의 온도를 자연스럽게 낮추어 주고 있으므로 항상 다이스(3) 내부는 낮은 온도를 일정하게 유지하고 있게 되는 것이다.As described above, the present invention naturally lowers the internal temperature by the asbestos insulating material 31 formed in the die 3, so that the die 3 always maintains the low temperature constantly.
이와같이 다이스(3)의 내부온도는 외주면의 온도보다 항상 낮기 때문에 인출심사인 피복강선(5)을 다이스(3)의 내부의 관통공(33)에 삽입하더라도 피복(51)은 벗겨지지 않고 다이스(3)의 외측에 주입된 원료액과 같이 다이스(3)를 통과하여 다이스(3)와 근접하게 장착된 성형기(4)로 이동하게 되는 것이다.In this way, since the internal temperature of the die 3 is always lower than the temperature of the outer circumferential surface, even if the coated steel wire 5, which is a drawing examination, is inserted into the through hole 33 in the interior of the die 3, the sheath 51 is not peeled off. Like the raw material liquid injected to the outside of 3), it passes through the die 3 and moves to the molding machine 4 mounted close to the die 3.
상기 성형기(4)로 이동된 원료액은 성형기(4)에 의해 지중전선관(6)이 성형됨과 동시에 내부에는 인출심사인 피복강선(5)이 삽입이 되는 것이다. 이때 다이스(3)의 내부온도가 낮은 온도로 항상 일정하게 유지되고 있으므로 지중전선관(6)을 성형할때에도 지중전선관(6)의 두께에 변형이 전혀없이 일정한 두께를 유지하는 양질의 제품을 제조할 수 있게 되는 것이다. 그리고 상기 성형된 지중전선관(6)은 인취기(7)에 의해 인취되어 물래(8)에 일정한 길이로 감아 출고가 되는 것이다.In the raw material liquid moved to the molding machine 4, the underground wire pipe 6 is molded by the molding machine 4, and the coated steel wire 5, which is drawn out, is inserted therein. At this time, since the internal temperature of the die 3 is constantly maintained at a low temperature, it is possible to manufacture a high-quality product that maintains a constant thickness without any deformation in the thickness of the underground cable tube 6 even when the underground cable tube 6 is molded. It will be possible. And the molded underground wire tube 6 is taken out by the take-off machine 7 is to be shipped to the factory 8 wound to a certain length.
이와같이 된 본 고안의 지중전선관(6)을 지하에 매설할시에 지중전선관(6)의 내부에 인출심사인 피복강선(5)이 삽입되어 있으므로 지중전선관(6)으로 전선을 삽입할때에는 인출심사인 피복강선(5)에 전선을 연결하여 준후 타측에서 피복강선(5)을 당겨줌으로써 전선의 매설작업은 용이하게 되는 것이다.When the underground conduit tube 6 of the present invention is buried underground, the coated steel wire 5, which is the drawing examination, is inserted into the underground conduit tube 6, so that when the electric wire is inserted into the underground conduit tube 6, After the wire is connected to the phosphorus coated steel wire 5, the wire laying operation is facilitated by pulling the coated steel wire 5 from the other side.
상기에서 설명한 바와같이 본 고안은 압출기에서 유도되는 원료액을 성형기로 송출하는 다이스의 내부에 석면단열재를 형성하여 줌으로써 외부에서 내부로 발산되는 높은 열을 차단시켜서 내부의 온도를 일정한 온도로 낮추어 주도록 하였기 때문에, 종전과 같이 에어펌프와 같은 별도의 설비장비를 설치하지 않고도 인출심사인 피복강선을 지중전선관에 간단히 삽입할 수 있음은 물론 양질의 제품을 제조할 수 있는 것이다.As described above, the present invention forms an asbestos heat insulating material inside the die which sends the raw material liquid derived from the extruder to the molding machine, thereby lowering the internal temperature to a constant temperature by blocking high heat emitted from the outside. Therefore, it is possible to simply insert the coated steel wire that is drawn out into the underground conduit tube as well as to manufacture a high-quality product without installing a separate equipment such as an air pump.
따라서 본 고안은 지중전선관에 인출심사인 피복강선을 삽입하는데 있어서 공정이 간단하여 원가절감을 유도할 수 있음은 물론 생산의 능률을 향상하게 되어 경쟁력이 증가 할 수 있게 되는 것이다.Therefore, the present invention is simple in the process of inserting the coated steel wire withdrawal screening in the underground conduit can lead to cost reduction, as well as to improve the efficiency of production to increase the competitiveness.
