본 발명은 평각선 제조방법에 관한 것으로, 보다 상세하게는 알루미늄 피복 와이어의 양측면이 평각을 이루도록 성형하여 모음다이에서 집합체로 꼬여진 후 압축롤러에 의해 가압하여 단면이 원형을 이루게 만드는 평각선 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a flat line, more specifically, a flat line manufacturing method for forming both sides of the aluminum sheathed wire to form a flat, twisted into an assembly in the collection die and pressurized by a compression roller to form a cross section. It is about.

일반적으로, 알루미늄 피복 와이어는 중심은 철이고, 그 주위를 알루미늄이 둘러싸고 있는 형태로서, 상기 알루미늄 피복 와이어를 사용한 평각선 제조방법은 보빈과 모음다이의 사이에 성형장치를 설치하여, 알루미늄 피복 와이어를 통과시켜서 성형소선을 만들고, 상기 성형소선을 모음다이를 통과시켜 각 소선을 모은 후, 수평, 수직 압축롤러를 통과시켜서 최종적으로 집합된 송전선, 가공지선, 광복합 가공지선을 만드는 것으로 이루어진다.In general, an aluminum sheathed wire has a center of iron and is surrounded by aluminum. In the flat wire manufacturing method using the aluminum sheathed wire, a forming apparatus is provided between the bobbin and the vowel die to form an aluminum sheathed wire. After forming the molded wire by passing through, the molded wire passes through the vowel die to collect the individual wires, and then passes through horizontal and vertical compression rollers to make the finally assembled transmission line, processing land line, and optical composite processing land line.

이때, 상기 성형장치를 통과하여 만들어진 성형소선은 중심의 철심은 그대로 있고, 주위의 알루미늄만 소성 변형되어 미리 설정된 외경으로 만들어진 것이다.At this time, the molded element wire made by passing through the molding apparatus is the core of the core is intact, only the surrounding aluminum is plastically deformed is made of a predetermined outer diameter.

그러나, 상기 종래의 제조방법은 성형장치(롤러세트)와 설계된 성형소선 단면의 기하학적 구조로 인해서 성형롤러에 닿는 접촉 면적이 다르므로 성형되는 형태가 일률적으로 되지 않고, 중심의 철심이 성형소선의 중심에 있지 않는 편심진 구조로 성형이 되어 철심의 상부 알루미늄의 두께가 상대적으로 얇아지는 문제점이 있었다.However, in the conventional manufacturing method, since the contact area contacting the forming roller is different due to the geometry of the forming apparatus (roller set) and the designed cross section of the molded element wire, the shape to be formed is not uniform, and the center iron core is the center of the molded element wire. There was a problem that the thickness of the upper aluminum of the iron core is relatively thin because it is molded into an eccentric structure not present in the core.

또한, 상기 철심이 편심된 성형소선을 모음다이를 통과시켜 집합하고, 설계된 외경을 만들고, 소선들의 집합상태를 단단하게 하기 위해서 수평, 수직 압축롤러를 통과시키면서 압축을 하면, 집합된 소선의 바깥부분이 압축롤러의 미끄럼이나 눌림에 의해 알루미늄의 두께가 더욱 얇아지게 되고, 심할 경우 철심상부가 부분적으로 외부에 노출되는 문제점이 있었다. In addition, when the compacted wires eccentrically gathered by passing through the collection die, and designed to make the outer diameter designed, and compressed while passing through the horizontal and vertical compression roller in order to harden the assembled state of the wires, the outer portion of the aggregated wire The thickness of the aluminum becomes thinner by sliding or pressing of the compression roller, and in severe cases, there is a problem in that the upper portion of the iron core is partially exposed to the outside.

따라서, 상기 철심의 알루미늄의 두께는 최소 알루미늄 두께를 요구하는 일부 규격을 만족하지 못하여 불량제품으로 분류되는 문제점이 있었다.Therefore, the thickness of aluminum of the iron core does not meet some specifications that require a minimum aluminum thickness has a problem that is classified as a defective product.

이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로써, 알루미늄 피복 와이어가 일률적인 형상으로 성형되도록 하여, 알루미늄 내부에서 철심이 중심에 위치하도록 함으로써 철심 외부로는 알루미늄 두께가 일정하게 이루어지며, 압축롤러를 거치면서 알루미늄의 두께가 더욱 얇아지는 것을 방지하여 규격에 맞는 알루미늄 피복 와이어를 만드는 평각선 제조방법을 제공하는 것을 목적으로 한다.
Accordingly, the present invention has been devised to solve the above problems, the aluminum sheathed wire is formed into a uniform shape, so that the iron core in the center of the aluminum center is made of aluminum thickness outside the core. It is an object of the present invention to provide a flat wire manufacturing method for manufacturing aluminum coated wire that meets specifications by preventing the thickness of aluminum from becoming thinner while passing through a compression roller.

It characterized by including (30).

이하, 본 발명에 따른 평각선 제조방법의 작용 및 효과를 살펴본다.Hereinafter, the operation and effects of the flat line manufacturing method according to the present invention will be described.

상기 본 발명에 따른 평각선 제조방법에 따르면, 보빈(2)에서 풀려진 알루미늄 피복(1b) 와이어(1)는 성형단계(12)의 상부롤러(10a)와 하부롤러(10b)로 이루어진 롤러세트(10)에 의해 가압되어 성형되며, 이때 상부롤러(10a)의 그루브(3) 내측에 형성된 오목홈(5)에 의해서 철심(1a)을 둘러싼 알루미늄 피복(1b)이 성형된다.According to the manufacturing method of the flat wire according to the present invention, the aluminum coating (1b) wire (1) released from the bobbin (2) is a roller set consisting of the upper roller (10a) and the lower roller (10b) of the forming step 12 It is pressurized by 10 and shape | molded, At this time, the aluminum coating 1b surrounding the iron core 1a is shape | molded by the recessed groove 5 formed in the groove | channel 3 inside of the upper roller 10a.

즉, 상기 철심(1a)을 감싼 알루미늄 피복(1b)의 상부는 오목홈(5)이 형성된 상부롤러(10b)로 가압되어 오목홈(5)의 역형상인 돌출부(14)를 이루고, 알루미늄의 피복(1b)의 하부는 하부롤러(10b)로 가압되어 측면이 평각을 이루는 성형소선(13)이 된다.That is, the upper portion of the aluminum coating (1b) wrapped around the iron core (1a) is pressed by the upper roller (10b) formed with the concave groove (5) to form a projection 14 of the inverted shape of the concave groove (5), The lower portion of the sheath 1b is pressed by the lower roller 10b to form a molded element 13 having a flat side surface.

그리고, 상기 롤러세트(10)를 거친 와이어(1)는 집합단계(20)의 프리폼롤러(15)를 지나면서 굴절되어 소성변형이 되며, 변형된 와이어(1)는 모음다이(18)에서 모아져 나선형으로 꼬아진다.Then, the wire 1 passed through the roller set 10 is refracted as it passes through the preform roller 15 of the assembly step 20 to be plastically deformed, and the deformed wire 1 is collected in the collection die 18. Twisted spirally

그리고, 상기 모음다이(18)를 지난 와이어 집합체(23)는 가압단계(30)의 수평 압축롤러(25)를 거치면서 가압된 후, 수직 압축롤러(27)로 재차 가압되어 단면이 원형을 이루게 된다. 이때 수평 압축롤러(25)와 수직 압축롤러(27)에 의한 가압순서는 바뀔 수 있다. Then, the wire assembly 23 passing through the collection die 18 is pressed while passing through the horizontal compression roller 25 of the pressing step 30, and then pressed again by the vertical compression roller 27 to form a circular cross section. do. At this time, the pressing order by the horizontal compression roller 25 and the vertical compression roller 27 can be changed.

즉, 상기 롤러세트(10)의 오목홈(5)으로 성형된 와이어(1)의 알루미늄 피복(1b) 돌출부(14)는 수평 압축롤러(25), 수직 압축롤러(27)를 거치면서 평탄화되어 완성선(35)으로 만들어지고, 와이어(1)의 측면부는 평각으로 이루어진 상태에 서 서로 밀착되어 단면이 원형인 와이어 집합체(23)를 형성한다.That is, the projections 14 of the aluminum sheath 1b of the wire 1 formed into the concave grooves 5 of the roller set 10 are flattened while passing through the horizontal compression roller 25 and the vertical compression roller 27. It is made of a complete line 35, the side portions of the wire (1) in close contact with each other in a flat state to form a wire assembly 23 of a circular cross section.

이와 같이, 상기 와이어(1)의 철심을 둘러싼 알루미늄 피복(1b)은 롤러세트(10)의 상부롤러(10a)의 그루브(3)에 형성된 오목홈(5)으로 성형되어 돌출부(14)를 이루게 되며, 상기 알루미늄 피복(1b)의 돌출부(14)는 수평, 수직 압축롤러(25, 27)에서 평탄화되므로, 와이어(1)의 알루미늄 두께가 얇아지는 것은 방지된다.In this way, the aluminum sheath 1b surrounding the iron core of the wire 1 is formed into a concave groove 5 formed in the groove 3 of the upper roller 10a of the roller set 10 to form the protrusion 14. The projection 14 of the aluminum sheath 1b is flattened in the horizontal and vertical compression rollers 25 and 27, so that the aluminum thickness of the wire 1 is prevented from thinning.

따라서, 상기와 같이 구성된 본 발명은, 알루미늄 피복 와이어가 일률적인 형상으로 성형되고, 알루미늄 내부에서 철심이 중심에 위치하도록 함으로써 철심 외부로는 알루미늄 두께가 일정하게 이루어지며, 압축롤러를 거치면서 알루미늄의 두께가 더욱 얇아지는 것을 방지하여 규격에 맞는 알루미늄 피복 와이어를 얻는 효과를 얻을 수 있다.Therefore, the present invention configured as described above, the aluminum coating wire is molded in a uniform shape, by placing the iron core in the center inside the aluminum, the thickness of the aluminum is made constant outside the iron core, while passing through the compression roller of the aluminum The thickness can be prevented from becoming thinner, and the effect of obtaining an aluminum sheathed wire conforming to the standard can be obtained.
