Abstract

본 발명은 직선형 튜우브를 코일 스프링 형태로 형성한 코일형 튜우브에 관한 것으로서, 더욱 상세하게는 코일형 튜우브의 감김이 끝나는 양측의 튜우브가 튜우브의 코일링축과 동일하게 위치하도록 하여 사용시 코일형튜우브의 유동을 억제하여 엉키거나 꼬이지 않도록한 코일형튜우브 및 그 제조방법과 형성구에 관한 것이다.The present invention relates to a coiled tube formed by forming a straight tube in the form of a coil spring, and more particularly, when the tubing on both sides of which the coiled tube is wound is placed in the same position as the coiling shaft of the tube. The present invention relates to a coiled tube that suppresses the flow of the coiled tube so as not to be tangled or twisted, and a manufacturing method and a forming apparatus thereof.

종래에는 코일링된 양측부의 코일링되지 않은 튜브 부위가 코일링 회전원 외주에서 코일링축과 평행한 형태로 형성되어 작업시 위치 이동에 따른 심한 흔들림에 의해 엉키기 쉽고, 코일링튜브의 양측 코일링되지 않은 튜브 부위의 위치가 코일링 회전원의 원주상에 위치하므로 먼거리의 작업시 코일형 튜브의 펴짐으로 비틀림모멘트가 크게 작용하여 코일링튜브의 어느부분에서 코일링 방향의 역방향으로 꼬임되는 현상이 발생되는 폐단이 있었다. 따라서 본 발명은 코일형 튜브의 양측 직선부위의 위치가 편심되지 않고 코일링 축과 동일한 위치에 있으므로 작업 장소에 따라 위치 이동시 흔드림이 억제되어 튜브자체의 엉킴이 일어나지 않음과 동싱 비틀림 모멘트가 코일링 방향으로 작용하게 되어 튜브의 꼬임 현상이 발생되지 않도록 한 것이다.Conventionally, the uncoiled tube portion of the coiled both sides is formed in a shape parallel to the coiling shaft at the outer circumference of the coiling rotation source, and is easily entangled by severe shaking due to positional movement during work, and coiling both sides of the coiling tube Because the position of the uncoated tube is located on the circumference of the coiling rotation source, the torsion moment is greatly increased due to the unfolding of the coiled tube during a long distance operation, which causes twisting in the opposite direction of the coiling direction. There was a developed lung. Therefore, in the present invention, since the positions of the straight portions on both sides of the coiled tube are not eccentric and are in the same position as the coiling axis, the shaking is suppressed when the position is moved according to the working place so that the entanglement of the tube itself does not occur and the kinetic torsional moment is coiled. It acts in the direction to prevent the tube from twisting.
