본 고안은 고 내열성과 인장강도, 내파열성이 요구되는 자동차용 실리콘 3종/4종 호스(자동차의 과급기와 인터쿨러 사이에서 과급된 고온의 공기를 통과시키는 역할의 인터쿨러 호스와 자동차의 엔진과 라디에타 사이의 고온냉각수를 통과시키 는 역할의 라디에터호스 등)의 바람직한 제조방법과 그 장치에 관한 것이다.This design is for
통상 자동차의 부품 중 실리콘 3종 및 4종 호스(인터쿨러호스와 라디에터 호스 등)는 높은 온도의 기류를 통과시키는 특성 때문에 내열성과 내파열성(인장강도 등) 등이 우수한 실리콘 재질을 이용해 제조되는 특징을 가지고 있다.Among the parts of automobiles, silicone hoses such as three and four hoses (such as intercooler hoses and radiator hoses) are manufactured using silicone materials that are excellent in heat resistance and burst resistance (tensile strength, etc.) because of their high airflow characteristics. Have.
그런데 종래에는 실리콘 고무재질의 특이한 물리적 성질로 인하여 압출기를 이용한 연속제조법이 아니라 실리콘 고무와 보강천이 합체된 시트를 수작업 혹은 반자동 기계를 통해 원통형 호스금형 둘레를 감싸/말아서 제조하는 불합리한 제조방법을 취하고 있기 때문에 품질 및 생산성이 크게 저하되는 문제점이 있었다.However, due to the peculiar physical properties of the silicone rubber material, it is not a continuous manufacturing method using an extruder, but an irrational manufacturing method of manufacturing a sheet in which a silicone rubber and a reinforcing cloth are combined by wrapping or rolling a cylindrical hose mold by manual or semi-automatic machines. Due to this, there is a problem in that quality and productivity are greatly reduced.
이에 일간에서는 특허출원 10-1996-008706호에서와 같이 일방 고무튜브의 내측에 실리콘을 분사하여 피복시킨 후 고무튜브의 외측에 편직기에 의한 보강을 실시한 다음 다시 압착기로 외피 실리콘을 압착 피복하는 제조공법을 개시하고 있다. 그러나 이 또한 내열성이 요구되는 인터쿨러 호스에서 열에 취약한 고무튜브의 중간층 적용으로 인터쿨러 호스의 특성에 반하는 문제점이 있을 뿐 만 아니라, 고무튜브의 내측으로 실리콘 고무를 분사하여 붙이고 외측으로 압착하여 붙이는 등 그 작업 공정이 매우 복잡하고 까다로와 실제 양산 적용에 무리가 있고 특히 실리콘의 도포 방법(내측에 분사, 외측에 압착)에 있어 전열판으로 실리콘에 온도를 가하고 액상화된 실리콘재로서 공정을 진행하는 그 방법은 실리콘의 화학적 특성을 도외시한 실제 실현이 난이한 제조방법이라 할 수 있다.Therefore, in the day, as in Patent Application No. 10-1996-008706, a coating method is performed by spraying silicon on the inside of one rubber tube, and then reinforcing with a knitting machine on the outside of the rubber tube, and then press-coating the outer silicon with a press. Is starting. However, in this case, the intercooler hose, which requires heat resistance, has a problem against the characteristics of the intercooler hose due to the application of the intermediate layer of the rubber tube that is heat-sensitive. In addition, the rubber rubber is sprayed on the inside of the rubber tube and pressed to the outside. The process is very complicated and difficult to apply to actual mass production, and especially in the method of applying silicon (spraying on the inside and pressing on the outside), the method of applying the temperature to the silicon with a heat transfer plate and proceeding the process as a liquefied silicon material It can be said that the manufacturing method is difficult to realize the actual characteristics of the silicon.
이에 본 고안에서는 실리콘 고무의 특이한 물리적 성질을 극복해 연속적인 제조방법을 구현한 가운데 실리콘호스의 요구특성(내열성, 인장강도 등)까지 보다 향상시켜 생산성 향상 및 이를 통한 인건비 절감, 불량률 저하는 물론 이에 따른 재료비절감과 우수하고 균일한 품질유지 등이 보장되는 자동차용 실리콘 3종/4종 호스(인터쿨러 및 라디에터 호스 등)의 제조방법을 개시하는 것으로서, 우수한 내열성이 요구되는 인터쿨러 호스의 주재료인 실리콘의 특성을 고려한 효율적 압출조건과; 내열성, 인장강도 및 파열압을 만족하기 위한 호스의 효율적 보강구조와; 인터쿨러의 최종제품형상 유지 및 이를 위한 합리적인 가류(열처리)조건/순서를 확립하여 우수하고 경쟁력 있는 세계 품질의 인터쿨러 및 라디에타 호스의 실리콘호스를 제조할 수 있는 새로운 공법을 제공함에 주안점을 두고 그 기술적 과제로서 완성한 것이다.Therefore, the present invention overcomes the peculiar physical properties of silicone rubber and implements a continuous manufacturing method, and further improves the required characteristics (heat resistance, tensile strength, etc.) of the silicone hose to improve productivity, thereby reducing labor costs and lowering the defective rate. Disclosed is a method of manufacturing three types of automotive silicone hoses (such as intercoolers and radiator hoses), which are guaranteed to reduce material costs and maintain excellent and uniform quality. Efficient extrusion conditions in consideration of characteristics; An efficient reinforcing structure of the hose to satisfy heat resistance, tensile strength and bursting pressure; The technical problem is to maintain the final product shape of the intercooler and establish reasonable vulcanization (heat treatment) conditions / sequences to provide a new method for manufacturing excellent and competitive world quality intercooler and radiator hose silicone hose. It is completed as.

상기한 고무성형공정에서 압출된 성형된 내피의 외주둘레에 그 내피의 열처리 없이 바로 브레이딩, 닛팅, 스파이럴 방식의 편조기를 이용해 보강재를 편조하는 보강재편조공정과, Reinforcing material braiding process for braiding reinforcing material by braiding, knitting, spiral type braiding machine without heat treatment of the inner skin on the outer periphery of the molded endothelial extruded in the rubber molding process,
상기한 편조된 보강재의 외주면에 다시 연속성형 압출기(외압출기)를 이용해 외피를 성형하는 외피성형공정과;An outer shell forming step of forming an outer shell on the outer circumferential surface of the braided reinforcement by using a continuous molding extruder (extruder);
상기 내피, 편조사, 외피로 구성된 실리콘 3종, 4종 호스의 성형물을 일정한 길이로 절단하고 제품형상의 금형에 삽입한 상태에서 필요한 열처리온도로 열처리하여 형상을 고정하는 최종 열처리공정으로 각각 실시하여서 된 것이다.Each of the molded products of the three types and four kinds of hoses composed of the endothelial, single yarn, and the outer sheath are cut to a certain length and inserted into a mold of the product, and then heat treated at the required heat treatment temperature to fix the shape. It is.
이와 같이 된 본원은 호스의 실리콘 내피와 외피의 성형시 최종 열처리에 앞서 미세 열처리 되는 것을 방지하기 위해 저온(15~30℃)의 조건에서 압출이 이루어짐에 따라 고온불변의 실리콘재질의 특성에 따른 후가공 즉, 최종적인 고온 열처리단계에서 목표하는 최종 호스제품의 형상유지 불가문제를 사전에 방지하여 보다 우수한 품질의 인터쿨러 호스제조에 크게 일조할 수 있을 뿐 아니라.In this way, the present invention is the post-processing according to the characteristics of the high temperature invariant silicon material as the extrusion is made under low temperature (15 ~ 30 ℃) conditions in order to prevent the micro heat treatment prior to the final heat treatment during the molding of the silicone inner shell and the outer shell of the hose In other words, by preventing the problem of maintaining the shape of the final hose product in the final high temperature heat treatment step in advance, it can greatly contribute to the production of better quality intercooler hose.
특히, 실리콘 내피, 보강재, 외피로 다단계 성형에 있어 실리콘고무 재질의 일반적인 물리적 특성 즉 실리콘 재질의 열처리전에는 아주 극도로 연한 재질이어서 일반 고무호스의 성형 제조와 같이 내피 성형압출 후 경화전에 상온에서의 편조는 불가한 것으로 알려지고 인식되어져 온 종전의 개념을 뛰어넘어 극복하고 상온에서의 미 경화된 연질의 실리콘을 일반 상온에서 일반 고무호스와 동일하게 편조 및 보강을 실현하여 최종 열처리시 상기 실리콘 내피와 외피 모두 미세한 열처리현상조차 전혀 없는 순수 비경화된 성형물의 조건에서 최종적으로 고온 열처리 됨에 따라 원하는 제품모양의 형태와 인장강도, 내열성 등 요구품질을 확실하게 구현할 수 있는 아주 획기적인 방법이라 할 수 있다.In particular, the general physical properties of silicone rubber material in the multi-stage molding of silicone inner skin, reinforcement, and outer skin, that is, extremely soft material before heat treatment of silicone material, and braiding at room temperature before curing after endothelial molding extrusion, like molding of general rubber hose. Overcomes the conventional concept that has been known and recognized as impossible, and realizes braiding and reinforcement of uncured soft silicone at room temperature in the same manner as a general rubber hose at normal temperature, so that the silicon inner skin and the shell during final heat treatment All of them are highly heat treated under the condition of pure uncured moldings which have no microscopic heat treatment. Therefore, it is a very innovative way to reliably realize the required quality such as the desired product shape, tensile strength and heat resistance.
나아가 상기한 보강재는 내열성 뿐 아니라 방탄재료로 사용될 만큼의 우수한 인강강도를 가지고 있다는 케블라사, 노멕스, 탄소섬유사, 유리섬유사 등을 채용함에 따라 실리콘호스의 인장강도를 더욱 향상시키는데 지대한 역할을 담당할 수 있다.Furthermore, the above reinforcing material has a great role in further improving the tensile strength of the silicone hose by employing Kevlar, Nomex, carbon fiber, glass fiber yarn, etc., which have not only heat resistance but also excellent toughness to be used as a bulletproof material. I can be in charge.
이상과 같이 살펴본 본 발명의 실리콘호스 성형제조방법 및 그 장치는 내열성,인장강도 및 파열압을 요하는 실리콘 3종, 4종호스의 제조를 일반고무호스 제조공법에 접목함으로서 생산성, 원가, 품질확보라는 측면에서 일획을 긋는 획기적인 공법으로 국내시장뿐만 아니라, 세계시장까지 그 기대되는 바가 실로 다대한 방법이다.As described above, the silicone hose molding manufacturing method and apparatus of the present invention combines the production of three kinds and four kinds of hoses requiring heat resistance, tensile strength and bursting pressure with the general rubber hose manufacturing method to secure productivity, cost and quality. In this respect, the groundbreaking construction method is a great way to expect not only the domestic market but also the world market.
