피복 케이블 및 그의 제조방법{Steel strand cable and method thereof}Sheathed cable and manufacturing method thereof

본 발명은 각종 기기 또는 자동차에 사용되는 피복 케이블에 관한 것으로, 특히 손상된 피복수지를 통하여 유입된 부식원이 내부강선 전체에 퍼져서 부식이촉진됨을 방지하여 주는 피복 케이블 및 그의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to coated cables used in various equipment or automobiles, and more particularly, to a coated cable and a method of manufacturing the same, which prevent corrosion from being accelerated by spreading a corrosion source introduced through a damaged coated resin to an entire inner steel wire.

이전부터 각종 기기 또는 자동차의 브레이크부품 및 견인부품으로 여러 가닥의 와이어들을 꼬아서 만든 케이블을 사용하여 왔으나, 이러한 케이블은 내식성이 취약한 와이어들이 외부에 그대로 노출되어서 수분이나 염분(이하 부식원이라 통칭함)의 접촉에 의하여 쉽게 부식되므로, 사용수명이 크게 단축되는 결함을 가지는 것으로 알려져 있다.Previously, cables made by twisting wires of various strands were used as brake parts and traction parts of various devices or automobiles.However, these cables are exposed to the outside as wires that are poor in corrosion resistance are exposed to the outside. Since it is easily corroded by the contact of), it is known to have a defect that the service life is greatly shortened.

최근에는 상기한 문제점을 해결하고자 도 1에서와 같이, 여러 가닥의 와이어 (111)들을 꼬아서 만든 내부강선(110)의 외표면에 피복수지(120)를 형성하여서 된 피복 케이블(100)이 개발되어서 제공되고 있다. 이러한 피복 케이블(100)은 내식성이 취약한 와이어(111)로 형성된 내부강선(110)을 피복수지(120)로 감싸서 부식원의 접촉을 차단하여 주므로, 내부강선(110)의 부식을 방지하여 원래의 기계적인 특성을 그대로 유지하면서도 사용수명이 연장되는 등의 장점을 가지게 되었다.Recently, in order to solve the above problems, as shown in FIG. 1, a sheathed cable 100 was formed by forming a sheath 120 on an outer surface of an inner steel wire 110 made by twisting several strands of wires 111. It is being provided. The sheathed cable 100 wraps the inner steel wire 110 formed of the wire 111 having poor corrosion resistance with the coated resin 120 to block the contact of the corrosion source, thereby preventing corrosion of the inner steel wire 110 to prevent the original. It has the advantage of extending the service life while maintaining the mechanical properties.

그러나, 이와 같은 종래의 피복 케이블(100)은 내부강선(110)의 외표면에 피복수지(120)가 단순 피복되어서, 내부강선(110)의 와이어(111)들 사이에 형성되어 있는 꼬임 공극(112)들이 밀봉되지 못한 상태로 단면 내에 존재하게 되는 점을 감안하여 볼 때, 각종 기기 또는 자동차의 브레이크부품 및 견인부품으로 피복 케이블(100)을 사용할 때에, 외부에서 가해지는 충격에 의하여 피복수지(120)가 국부적으로 손상되면, 그 피복수지(120)의 손상부위를 통하여 부식원이 내부로 유입되고, 내부로 유입된 부식원은 내부강선(110)의 와이어(111)들 사이에 존재하는 꼬임 공극(112)을 통하여 침투되어서 내부강선(110) 전체에 퍼져서, 내부강선(110)이 부식원과 광범위하게 접촉하여 부식이 촉진되는 현상이 발생되므로, 원래의 기계적인 특성을 상실하게 될 뿐만 아니라, 사용수명이 크게 단축되는 등의 심각한 결과를 초래하게 되었다.However, in the conventional sheathed cable 100, the coated resin 120 is simply coated on the outer surface of the inner steel wire 110, so that the twisted voids formed between the wires 111 of the inner steel wire 110 ( In view of the fact that the 112 are not sealed and present in the cross section, when the sheathed cable 100 is used as a brake part and a towing part of various devices or automobiles, When the 120 is locally damaged, the corrosion source is introduced into the interior through the damaged portion of the coating resin 120, and the corrosion source introduced into the interior is twisted between the wires 111 of the internal steel wire 110. It penetrates through the air gap 112 and spreads all over the inner steel wire 110, so that the inner steel wire 110 contacts the corrosion source in a wide range so that corrosion is promoted, thereby not only losing the original mechanical properties. , use People were greatly serious consequences, such as being shortened.

본 발명은 내부강선을 감싼 피복수지의 손상부위를 통하여 내부로 유입된 부식원이 내부강선 전체에 퍼져서 부식이 촉진됨을 효율적으로 억제하여 주도록 구성하여서, 케이블로서 요구되는 기계적인 특성을 지속적으로 유지할 수 있게 하여 주는 동시에, 전체적인 내구성을 획기적으로 향상시켜 주는 고품질의 피복 케이블 및 그의 제조방법을 제공하는 데 목적이 있다.The present invention is configured to effectively suppress the corrosion is promoted by the spread of the corrosion source introduced into the interior through the damaged portion of the coating resin wrapped around the inner steel wire, it is possible to continuously maintain the mechanical properties required as a cable It is an object of the present invention to provide a high quality sheathed cable and a method of manufacturing the same, which significantly improve the overall durability.

이하, 본 발명의 피복 케이블을 첨부도면에 의하여 설명하면 다음과 같다.Hereinafter, the sheathed cable of the present invention will be described with reference to the accompanying drawings.

본 발명도 여러 가닥의 와이어(11)들을 꼬아서 형성되는 내부강선(10)과, 상기 내부강선(10)의 외표면을 감싸도록 피복 형성되는 피복수지(20)로 구성된 점에 있어서는 종래의 것과 기술개념을 같이 한다.The present invention is also composed of the inner steel wire 10 is formed by twisting the wires 11 of several strands, and the coating resin 20 is formed to cover the outer surface of the inner steel wire 10 and the conventional We share technology concepts together.

단, 본 발명의 피복 케이블(1)은 도 2에 도시되는 바와 같이, 상기 내부강선 (10)의 와이어(11)들 사이에 형성되는 미세한 꼬임 공극(12)들이 그 내부강선의 외표면을 감싸는 피복수지(20)로 채워져서 밀봉되도록 함을 기술구성상의 특징으로 한다.However, the sheathed cable 1 of the present invention, as shown in Figure 2, the fine twisted voids 12 formed between the wires 11 of the inner steel wire 10 is wrapped around the outer surface of the inner steel wire; It is characterized by the technical configuration to be filled with the coating resin 20 to be sealed.

이와 같이 구성되는 본 발명의 피복 케이블(1)은 내부강선(10)의 와이어(11)들 사이에 존재하는 꼬임 공극(12)들이 피복수지(20)로 채워져서 밀봉되기 때문에, 각종 기기 또는 자동차의 브레이크부품 및 견인부품으로 사용할 때에, 외부로부터 충격을 받아서 피복수지(20)에 발생된 국부적인 손상부위를 통하여 부식원이 내부로 유입되더라도, 와이어(11)들 사이의 꼬임 공극(12)들을 통하여 침투하려는 부식원을 원천적으로 차단하여서, 부식원이 내부강선(10)에 광범위하게 접촉하여 부식을 촉진시킬 기회를 인위적으로 제거함으로써, 내부강선(10)의 부식을 방지하여 기계적인 특성을 상실하는 일없이 제기능을 충실히 발휘할 뿐만 아니라, 내부강선 (10)의 수명을 연장시켜서 반영구적으로 사용할 수 있게 하여 주는 등의 장점을 가지게 되는 것이다.Since the sheathed cable 1 of the present invention configured as described above is filled with the sheathed voids 12 between the wires 11 of the inner steel wire 10 and filled with the sheathed resin 20, various devices or automobiles are used. Of the twisted voids 12 between the wires 11, even when the corrosion source flows into the interior through local damages generated in the coated resin 20 upon impact from the outside when used as a brake part and a traction part of the By fundamentally blocking the corrosion source to penetrate through, artificially eliminating the opportunity for the corrosion source to contact the inner steel wire 10 extensively to promote corrosion, thereby preventing corrosion of the inner steel wire 10 to lose mechanical properties. Not only does it faithfully exert its function, but also has the advantage of allowing it to be used semi-permanently by extending the life of the internal steel wire (10).

상기 내부강선(10)은 강철을 소재로 성형된 와이어(11)들로서 형성하여, 외부로부터 가해지는 인장력을 감당하는 기능을 수행하도록 한다.The inner steel wire 10 is formed of steel as wires 11 formed of a material, so as to perform a function of handling the tensile force applied from the outside.

본 발명의 실시예에서, 상기 내부강선(10)은 여러 가닥의 와이어(11)들을 조밀하게 꼬아서 전체적으로 원형의 단면형상을 가지며, 그 와이어들 사이에 미세한 꼬임 공극(12)들이 형성된 것으로 예시되어 있다.In the embodiment of the present invention, the inner steel wire 10 is twisted by twisting several strands of wires 11 to have an overall circular cross-sectional shape, and is illustrated as having fine twisted voids 12 formed between the wires. have.

상기 피복수지(20)는 상기 내부강선(10)의 외표면을 감싸도록 피복 형성하여서, 부식원이 상기 내부강선(10)에 접촉하지 못하도록 차단하여 주는 기능을 수행하도록 한다.The coating resin 20 is formed to cover the outer surface of the inner steel wire 10, to perform a function to block the corrosion source from contacting the inner steel wire (10).

그리고, 상기 피복수지(20)는 상기 내부강선(10)의 와이어(11)들 사이에 형성되는 미세한 꼬임 공극(12)들마다 채워져서 밀봉되도록 형성함이 중요하다. 그이유는, 외부에서 가해지는 충격으로 피복수지(20)에 발생된 국부적인 손상부위를 통하여 부식원이 내부로 유입되더라도, 와이어(11)들 사이의 꼬임 공극(12)들을 통하여 침투하려는 부식원을 차단하여서, 부식원이 내부강선(10) 전체에 퍼져서 부식이 촉진되는 현상을 억제하여 주도록 하기 위함이다.In addition, it is important that the coating resin 20 is formed to be filled and sealed for each of the fine twisted voids 12 formed between the wires 11 of the inner steel wire 10. The reason is that even though the corrosion source enters through the local damage generated on the coated resin 20 due to an external impact, the corrosion source tries to penetrate through the twisted voids 12 between the wires 11. By blocking the corrosion source is to suppress the phenomenon that the corrosion is promoted by spreading throughout the inner steel wire (10).

이하, 본 발명의 피복 케이블의 제조방법을 첨부도면에 의하여 설명하면 다음과 같다.Hereinafter, the manufacturing method of the covering cable of this invention is demonstrated by drawing.

본 발명도 여러 가닥의 와이어(11)를 꼬아서 형성된 내부강선(10)이 피복수지 압출기(2)를 경유하게 하여서, 그 내부강선(10)의 외표면에 피복수지(20)가 피복 형성되도록 한 점에 있어서는 종래의 것과 기술개념을 같이 한다.The present invention also allows the inner steel wire (10) formed by twisting wires (11) of several strands via the coated resin extruder (2), so that the coated resin (20) is coated on the outer surface of the inner steel wire (10). In one aspect, the technical concept is the same as the conventional one.

단, 본 발명의 피복 케이블의 제조방법은 도 3에 도시되는 바와 같이, 상기 피복수지(20)가 피복되기 이전의 내부강선(10)이 상기 피복수지 압출기(2)의 전방에 배치되는 열처리수단(3)을 경유하게 하여 미리 고온으로 가열한 후에, 고온으로 가열된 상태의 내부강선(10)이 상기 피복수지 압출기(2)를 경유할 때에 그 외표면에 피복수지(20)가 피복 형성되도록 하여서, 상기 내부강선(10)의 외표면에 피복되는 피복수지(20)가 와이어(11)들 사이에 형성된 미세한 꼬임 공극(12)들 내에 채워져서 밀봉되도록 제조함을 기술구성상의 특징으로 한다. 이와 같이 제조된 피복 케이블(1)은 그 피복수지(20)가 경화되도록 하면서 별도의 권취드럼(4)에 권취하여서 피복 케이블(1)의 제조를 완료하게 된다.However, in the method of manufacturing the coated cable of the present invention, as shown in FIG. 3, the heat treatment means in which the inner steel wire 10 before the coated resin 20 is coated is disposed in front of the coated resin extruder 2. After the heating to a high temperature in advance via (3), when the inner steel wire 10 heated to a high temperature passes through the coated resin extruder 2, the coated resin 20 is coated on its outer surface. Thus, it is characterized in that the coating resin 20 coated on the outer surface of the inner steel wire 10 is manufactured to be filled and sealed in the fine twisted voids 12 formed between the wires (11). The sheathed cable 1 thus manufactured is wound on a separate winding drum 4 while the sheathing resin 20 is cured, thereby completing the manufacture of the sheathed cable 1.

Since the coated resin 20 melt-extruded to cover the outer surface of the inner steel wire 10 passing through the heated state is filled in the twisted voids 12 between the wires 11 and sealed, it is applied from the outside. To prevent the corrosion source from entering the interior through the local damage areas generated in the coated resin 20 through the twisted voids 12 between the wires 11 so as not to penetrate the entire inner steel wire 10. The shielded cable 1 which can be cut off can be obtained.

상기 열처리수단(3)은 상기 내부강선(10)에 대하여 단시간에 고온으로 가열하여 줄 수 있는 고주파가열기를 사용함이 바람직하다. 이 고주파가열기는 일정한 속도로 통과하는 내부강선(10)에 대하여 고온으로 신속히 가열처리하기에 적합한 장점을 가진다.Preferably, the heat treatment means 3 uses a high frequency heater that can heat the inner steel wire 10 at a high temperature in a short time. This high frequency heater has the advantage of being suitable for rapid heat treatment at high temperature with respect to the internal steel wire 10 passing at a constant speed.

상기 피복수지 압출기(2)는 내부를 통과하는 고온의 내부강선(10)에 대하여 겔상태의 피복수지(20)를 압출하여서, 상기 내부강선(10)의 꼬임 공극(12)들 내에 채워지면서 외표면 전체에 감싸지는 피복수지(20)를 성형하여 주게 된다.The coated resin extruder 2 extrudes the coated resin 20 in a gel state with respect to the high temperature inner steel wire 10 passing through the inside, and is filled in the twisted voids 12 of the inner steel wire 10. The coated resin 20 is formed to cover the entire surface.

여기에서, 상기 내부강선(10)은 별도의 권취드럼(5)에 감아서 열처리수단(3)과 피복수지 압출기(2)를 향하여 연속적으로 공급할 수 있도록 조치함이 바람직하다.Here, the inner steel wire 10 is preferably wound around a separate winding drum 5 so as to be continuously supplied toward the heat treatment means 3 and the coated resin extruder 2.

이상에서 살펴 본 바와 같이, 본 발명은 내부강선의 와이어들 사이에 존재하는 꼬임 공극들이 피복수지로 채워져서 밀봉되게 하여, 내부강선을 감싼 피복수지의 손상부위를 통하여 내부로 유입된 부식원이 내부강선 전체에 퍼져서 부식이 촉진되는 현상을 억제하여 줌으로써, 내부강선의 부식을 방지하여 기계적인 특성을 상실하는 일없이 제기능을 충실히 발휘할 뿐만 아니라, 내부강선의 수명을 연장시켜서 반영구적으로 사용할 수 있게 하여 주는 등의 유용한 효과를 가지는 발명인 것이다.As described above, the present invention allows the twisted voids existing between the wires of the inner wire to be filled with the coated resin to be sealed, so that the corrosion source introduced into the inside through the damaged part of the coated resin surrounding the inner wire By suppressing the phenomenon that corrosion is promoted by spreading throughout the steel wire, it prevents the corrosion of the internal steel wire and not only exerts its function properly without losing mechanical characteristics, but also extends the life of the internal steel wire so that it can be used semi-permanently.
