본 발명은 호스본체의 내·외부면에 내부와이어와 외부와이어가 각각 적층 결합된 구조를 갖는 적층식 호스를 제조하는 방법에 관한 것으로, 더욱 상세하게는 호스본체의 내주면에 장착되는 내부와이어와 호스의 형상을 만들기 위한 금속지지체 사이에 압축공기의 주입여부에 따라 외주직경이 팽창·축소되어지도록된 탄성부재를 삽입시킨 상태에서 적충식 호스를 제조함으로서, 성형완료된 호스본체와 그 내부의 지지체와의 분리공정이 간편하게 이루어질 수 있도록 한 탄성부재를 이용한 적층식호스의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a laminated hose having a structure in which the inner wire and the outer wire are laminated and bonded to the inner and outer surfaces of the hose body, and more specifically, the inner wire and the hose mounted on the inner circumferential surface of the hose body. By manufacturing the replenishment type hose while inserting the elastic member to expand and contract the outer circumferential diameter depending on whether the compressed air is injected between the metal supports to make the shape of the shape of the hose body and the support therein. It relates to a method of manufacturing a laminated hose using an elastic member so that the separation process can be made easily.
내·외주면에 내부와이어와 외부와이어가 적층된 구조를 갖는 적층식호스의 일반적인 제조공정은 호스의 형상을 만들기 위한 환봉형태의 금속지지체 외주면에 내부와이어를 덧씌우는 단계와; 상기 내부와이어의 외주방향으로 호스본체를 성형시키는 단계; 그리고 성형완료된 호스본체 외주면에 외주와이어를 덧씌우는 단계로 구분되어 진다.The general manufacturing process of the laminated hose having a structure in which the inner wire and the outer wire are laminated on the inner and outer circumferential surfaces includes: covering the inner wire on the outer circumferential surface of the metal support in the form of a rod to form a hose; Forming a hose main body in an outer circumferential direction of the inner wire; And it is divided into the step of overlaying the outer circumference wire on the outer peripheral surface of the molded hose body.
한편, 적층식 호스본체 제조시 호스형상을 만들기 위해서는 원형으로된 금속지지체위에 합성수지제 등의 재료를 적층하여 본체를 성형시키게되는데 이 과정에서 적층성형에 사용되는 합성수지 재료는 가열시 열변형에 의한 수축현상이 발생하게되고 따라서, 최초 성형된 호스본체의 내경은 적층재료의 수축현상으로 인하여 내경이 줄어들게되어 호스본체와 지지체 사이에 있는 내부와이어가 지지체의 외주면에 긴밀하게 압착되게 된다. 즉, 이 압착력으로 말미암아 호스본체의 내주면에 장착된 나선형의 내부와이어는 호스본체와 지지체 사이에서 형태변형을 일으키게되는 것이다.On the other hand, in order to make a hose shape when manufacturing a laminated hose body, a material such as a synthetic resin is laminated on a circular metal support to form a main body. In this process, the synthetic resin material used for the laminated molding shrinks due to heat deformation during heating. As a result, the inner diameter of the initially formed hose body is reduced due to shrinkage of the laminated material, and the inner wire between the hose body and the support is pressed against the outer circumferential surface of the support. That is, due to this pressing force, the spiral inner wire attached to the inner circumferential surface of the hose main body causes deformation of the shape between the hose main body and the support.
그러므로 호스본체의 성형이 완료된 후 지지체와 호스본체의 분리시 이들 상호간에는 강한계면장력이 존재하여 이를 해소하기 위하여 별도의 외압을 부여하여야만 분리가 가능하게 되며 이에는 통상, 수압이나 유압펌프를 이용하여 호스내부로 강한 압력을 부가하여 강제 발취를 하거나 또는 지지체의 양단에 별도의 말단 연결부를 부착하여 이 연결부를 강제적으로 잡아당기는 방식을 사용하게 되는데 이경우 외부에서 가해지는 강제적인 힘으로 말미암아 필연적으로 호스를 구성하는 본체가 손상을 입거나 그 내·외부에 장착된 와이어가 형태변형을 일으키게 된다.Therefore, after the molding of the hose body is completed, when the support body and the hose body are separated, there is a strong interfacial tension between them, so that the separation is possible only by applying a separate external pressure to solve this problem, and usually, using a hydraulic pressure or a hydraulic pump Forced extraction by applying a strong pressure inside the hose or a separate end connection at both ends of the support is used to force the connection. The main body constituting the body is damaged or the wires mounted on the inside and outside of the body cause deformation.
이에 본 발명은 상기와 같은 제반 문제점을 해소시키기 위해 안출된 것으로, 호스본체의 성형작업후에 호스본체와 지지체와의 분리공정이 용이하면서도 간편하게 이루어질 수 있도록 하여 호스본체의 성형작업성을 높이고 호스본체의 형태변형을 방지할수 있도록 한 적층식 호스의 제조방법을 제조방법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to facilitate the easy separation process of the hose body and the support after the hose body forming operation to increase the molding workability of the hose body and the hose body It is an object of the present invention to provide a method for manufacturing a laminated hose to prevent shape deformation.
상기의 목적을 달성시키기 위한 본 발명에 따른 적층식호스의 제조방법은, 금속 제로된 환봉상의 지지체 외주면에 압축공기의 주입여부에 따라 직경변화가 가능한 탄성체를 부가하여 이 탄성체의 변형, 즉 팽창 수축에 의한 외경변화로 호스본체의 내주면과 지지체와의 간격을 조정할수 있도록하여 호스본체와 지지체와의 분리공정을 용이하게 할수 있도록한 것에 그 특징이 있다.The method for manufacturing a laminated hose according to the present invention for achieving the above object, by adding an elastic body that can be changed in diameter depending on whether the compressed air is injected to the outer peripheral surface of the metal rod-shaped support body deformation, that is, expansion shrinkage It is characterized in that the separation between the hose body and the support can be facilitated by adjusting the distance between the inner circumferential surface of the hose body and the support by changing the outer diameter.
이하 본 발명에 따른 적층식호스의 제조방법을 첨부된 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, a method of manufacturing a laminated hose according to the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 예시도면 제3도의 (a)에 도시된 바와같이 금속제로 제작된 지지체(1) 외주면에 탄성체(2)를 결합시키게 된다. 이 탄성체(2)의 재질은 합성고무재 튜브와 같은 수축, 팽창이 자유로운 것이 바람직하며 그 중앙부에는 공간부(2a)가 형성되어 공간부(2a)내로의 공기유입량에 따라 탄성체의 외부직경이 변화할 수 있도록 되어 있다.According to the present invention, the elastic body 2 is coupled to the outer peripheral surface of the support body 1 made of metal as shown in FIG. It is preferable that the material of the elastic body 2 is free of shrinkage and expansion like a synthetic rubber tube, and a space portion 2a is formed at the center portion thereof so that the outer diameter of the elastic body changes according to the amount of air flow into the space portion 2a. You can do it.
즉 탄성체(2)의 공간부(2a)내부로 압축공기를 장입시켜 원하는 호스본체의 내경을 얻을수 있을 만큼 탄성체(2)의 직경을 제3도의 (b)와 같이 팽창시키게 되는데, 이때 탄성체(2)의 외주면이 내부와이어(3)의 내경보다 작도록하면 예시도면 제3도의 (c)와 같이 내부와이어(3)의 끼움동작이 원활하게 이루어진다.That is, the diameter of the elastic body 2 is expanded as shown in (b) of FIG. 3 so that the compressed air is charged into the space 2a of the elastic body 2 to obtain the desired inner diameter of the hose body. When the outer circumferential surface of the inner wire 3 is smaller than the inner diameter of the inner wire 3, the fitting operation of the inner wire 3 is smoothly performed as shown in FIG. 3C.
이 상태에서 탄성체(2)의 공간부(2a)내에 2차로 공기를 주입하여 예시도면 제3도의 (d)와 같이 내부와이어(3)의 내주면에 탄성체(2)가 밀착될때까지 팽창시켜 내부와 이어(3)의 흔들림을 방지시키며, 상기의 공정에이어 내부와이어(3)의 외주면에 합성 수지제를 적층시켜 호스본체(4)를 예시도면 제3도의 (e)와 같이 성형시킨다.In this state, air is injected into the space portion 2a of the elastic body 2 secondly, and as shown in (d) of FIG. 3, it expands until the elastic body 2 adheres to the inner circumferential surface of the inner wire 3 so as to be in close contact with the inside. The shaking of the ear 3 is prevented, and the hose body 4 is molded as shown in FIG. 3E by laminating a synthetic resin on the outer circumferential surface of the inner wire 3 following the above process.
호스본체(4)의 성형이 완료되어지면 탄성체(2)의 공간부(2a)내에 유입된 압축공기를 배출시켜 예시도면 제3도의 (f)와 같이 탄성체(2)의 외주직경을 축소시키는데 이는 내부와이어(3)의 내주면과 탄성체(2)의 외주면 사이에 간극(5)을 발생시킴으로서 호스본체(4)와 탄성체(2)를 포함하는 지지체(1)와의 분리공정을 원활하게 할수가 있다.When the molding of the hose body 4 is completed, the compressed air introduced into the space 2a of the elastic body 2 is discharged to reduce the outer circumferential diameter of the elastic body 2 as shown in FIG. 3 (f). The gap 5 is generated between the inner circumferential surface of the inner wire 3 and the outer circumferential surface of the elastic body 2 to facilitate the separation process between the hose body 4 and the support 1 including the elastic body 2.
따라서 예시도면 제3도의 (g)와 같이 형태변형되지 않은 적충식호스(A)를 최종적으로 얻을 수가 있다.Therefore, as shown in (g) of FIG. 3, an unformed red locomotive hose A can be finally obtained.
상기와 같은 제조공정에 의해 적충식호스(A)가 제조되어짐에 따라 다음과 같은 효과가 발생되는바,As the red horn hose (A) is manufactured by the manufacturing process as described above, the following effects are generated,
첫째 ; 지지체(1)에 대한 내부와이어(3)의 삽입성이 좋아지고,first ; Insertion of the inner wire 3 into the support 1 is improved,
둘째 ; 탄성체(2)의 외주직경에 따라 호스본체(4)의 내경이 결정되므로 다양한 치수의 적층호스를 제조할수 있는 잇점과 호스본체(4) 내경의 정확한 치수조절이 가능하며,second ; Since the inner diameter of the hose main body 4 is determined according to the outer circumferential diameter of the elastic body 2, the advantage of manufacturing laminated hoses of various dimensions and the accurate dimension adjustment of the inner diameter of the hose main body 4 are possible.
셋째 ; 호스본체(4)의 성형시 탄성체(2)의 자체탄성에 의하여 각 층간의 형상유지가 용이하게 되는 장점이 있으며,third ; When the hose body 4 is formed, the elasticity of the elastic body 2 has an advantage that it is easy to maintain the shape between the layers,
넷째 ; 호스본체(4)의 성형작업 완료후 별도의 가압장치가 없이도 지지체(1)와 호스본체(4)간의 분리공정이 원활하게 이루어지고 또한, 내·외부 와이어(3)(6)를 포함한 호스본체(4)의 형태가 전혀 변형됨이 없이 상기 분리공정이 완료된다는 장점이 있다.fourth ; After the molding operation of the hose body 4 is completed, the separation process between the support body 1 and the hose body 4 is smoothly performed without a separate pressurizing device, and the hose body including the inner and outer wires 3 and 6 is provided. There is an advantage that the separation process is completed without any modification of the form of (4).
상기와 같이 본 발명에 따른 적층식호스의 제조방법은 적층식호스의 제조공정에 있어서, 호스본체(4)의 내주면에 삽입되어지는 내부와이어(3)와 지지체(1)사이에 압축공기의 주입여부에 따라 축소·팽창되어지는 탄성체(2)를 삽입시킨 상태에서 적층식호스를 제조함으로서, 종래의 제조방법보다 생산성이 향상될 뿐만 아니라 신뢰성 있는 제품이 양산되어질수 있는 매우 유용한 발명인 것이다.As described above, in the manufacturing method of the laminated hose according to the present invention, the compressed air is injected between the inner wire 3 and the support 1 inserted into the inner circumferential surface of the hose main body 4 in the manufacturing process of the laminated hose. By manufacturing the laminated hose in the state in which the elastic body 2 is reduced and expanded depending on whether or not it is inserted, it is a very useful invention that not only can the productivity be improved but also a reliable product can be mass-produced compared to the conventional manufacturing method.
