Abstract

PURPOSE: A pipe engagement coupling machined by the press working is provided to fix a branched pipe to a main pipe in a vertical manner and make a seal by inserting a packing between the end of the branched pipe and protruded insertion. CONSTITUTION: A branched pipe(2) is inserted into a circular hole(1a) of a main pipe(1). A packing(3) is fitted into the engagement of the branched pipe(2). An upper band is engaged with a lower band to support the branched pipe on the main pipe in a vertical manner. A coupling(10) consists of an end supporting ring(11), a protruded insertion(12) into which the packing is inserted, and the upper band. The coupling is pressed into a single part. The branched pipe passes through the end supporting ring into the circular hole of the main pipe. The branched pipe is attached to the end supporting ring with a press working.

Description

프레스 성형으로 가공한 지관이음용 커플링 {Coupling manufactured by pressing for connecting manifold}Coupling manufactured by pressing for connecting manifold}

본 발명은 본관에 원형공을 뚫고 지관을 연결할 때 사용하는 지관이음용 연결구를 프레스 성형으로 가공한 지관이음용 커플링에 관한 것이다.The present invention relates to a coupling for a paper pipe joint processed by press molding a connector for a paper pipe joint used to connect a paper pipe through a circular hole in the main pipe.

지금까지 지관을 연결할 때 사용되는 지관이음용 연결구는 본관의 원형공에 삽입될 지관하부의 외측으로 패킹이 삽입되고 지관을 수직으로 지지시켜 줄 지지관이 이중으로 형성되게 하부를 ｈ형으로 구성시켜야 하므로 제조시 필히 주물로 성형하므로서 생산량이 한정되고 또한 주물성형품의 후가공처리와 이 연결구를 하부밴드와 체결하기 위하여 별개체의 상부밴드를 연결구에 부착시켜야 하는 제조공정 등으로 인하여 제조원가가 상승되었다.Until now, the joints used for connecting pipes should be composed of ｈ type so that the packing is inserted into the outside of the lower part of the pipe to be inserted into the circular hole of the main pipe, and the supporting pipe is vertically formed to support the pipe vertically. Therefore, the production volume is limited due to the molding process, and the manufacturing cost is increased due to the post-processing of the cast moldings and the manufacturing process of attaching the upper band of the separate body to the connector in order to fasten the connector with the lower band.

본 발명에서는 이와같은 문제점들을 해결하기 위하여 본관의 원형공에 지관을 연결할 때 사용하는 지관이음용 연결구를 지관외경과 내경이 일치하는 선단지지링과 그 하부를 ㄱ형으로 확대하여 패킹이 삽입될 돌출삽입단을 그리고 돌출삽입단의 양측으로 상부밴드가 형성되게 전체를 프레스 가공으로 성형시키고 이렇게 프레스 가공으로 성형시킨 연결구에 지관을 선단지지링의 내부로 지관 하단부가 본관의 원형공에 삽입될 길이로 가압 삽입시킨 후 선단지지링과 지관을 일체가 되게 부착시켜서 프레스 가공에 의한 대량 생산과 간편한 제조공정으로 제조원가를 절반 이하로 줄일 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, in order to solve these problems, the connector for connecting the branch pipe used to connect the branch pipe to the circular hole of the main pipe, and the protruding insert into which the packing is inserted by expanding the lower end support ring and the lower portion of the inner tube having the same inner diameter as the a-shape. The end is formed by pressing the whole part to form upper bands on both sides of the protruding insertion end, and presses the branch pipe into the end support ring to be inserted into the circular hole of the main pipe into the end support ring. After inserting, the end support ring and the branch pipe are integrally attached to reduce the manufacturing cost to less than half by mass production and simple manufacturing process by press working.
