Description

호스용 연결금구 결합방법 및 그 연결금구 {Hose connection fittings and method of combining the same}Hose connection fittings and method of combining the same

본 발명은 호스용 연결금구 결합방법 및 그 연결금구에 관한 것으로서, 더욱 상세하게는 자동차의 파워스티어링 호스 등의 연결금구의 제작시 제작공정을 최소화한 호스용 연결금구 결합방법에 관한 것이다.The present invention relates to a method for coupling a connection bracket for a hose, and more particularly, to a method for coupling a connection bracket for a hose which minimizes a manufacturing process in manufacturing a connection bracket such as a power steering hose of an automobile.

종래의 호스용 연결금구는 슬리브, 파이프, 니플을 고착시키는데 있어서Conventional hose fittings are used to secure sleeves, pipes, and nipples.

첫째, 도 1에 도시한 연결용 금구는 파이프(50), 니플(20), 볼트(70), 슬리브(10)로 구성되어 볼트로 체결하여 고정하였다.,First, the connection bracket shown in Figure 1 is composed of a pipe 50, the nipple 20, the bolt 70, the sleeve 10 is fastened with a bolt.

둘째, 도 2에 도시한 연결용 금구는 파이프(50)와 니플(20)을 일체화하여 슬리브와 고착시키는 데 있어 싱글 또는 더블비드를 형성 고착하여 결합하였다.Second, the connecting bracket shown in FIG. 2 was formed by attaching a single bead or a double bead in the pipe 50 and the nipple 20 to be integrally fixed to the sleeve.

셋째, 도 3a, 3b에 도시한 호스용 연결금구는 파이프(50), 니플(20), 슬리브 (10)로 구성하여 파이프(50)와 니플(20)을 브레이징용접하여 결합하였다.Third, the connection bracket for the hose shown in Figures 3a, 3b is composed of a pipe 50, nipple 20, sleeve 10 was joined by brazing welding the pipe 50 and the nipple 20.

넷째, 도 4에 도시한 호스용 연결금구는 니플(20)과 파이프(50)의 접촉부 (30-1)를 브레징용접하여 결합하거나, 니플과 슬리브(10)를 가체결(30-2)하여 결합하였다.Fourth, the hose connecting bracket shown in FIG. 4 is joined by brazing welding the contact portion 30-1 of the nipple 20 and the pipe 50, or by pre-fastening the nipple and the sleeve 10 30-2. Combined.
