Description

파이프로 제작된 조인트부재 및 그 제조방법{omitted}Joint member made of pipe and manufacturing method thereof

본 발명은 파이프로 제작된 조인트부재 및 그 제조방법에 관한 것으로 특히 납성분으로 인한 유해성 검사가 필요없는 스테인레스 재질의 파이프를 이용하여 다양한 모양의 조인트부재를 프레싱 작업과 인서트물 압입작업에 의해 제작할 수 있도록 한 것이다.The present invention relates to a joint member made of a pipe and a method for manufacturing the same, in particular, a joint member having various shapes can be manufactured by pressing and insert inserting operations using a stainless steel pipe that does not require a hazard test due to lead components. It would be.

일반적으로 주름관 또는 직관을 위한 조인트부재는 외경에 나사부가 형성되거나 관통공에 나사공이 형성되며, 상기 관통공에는 패킹과 압착링을 포함한 조인트수단이 정해진 위치에 설치될 수 있는 단턱 또는 경사턱부를 갖는다.In general, a joint member for a corrugated pipe or a straight pipe has a threaded portion formed in an outer diameter or a threaded hole formed in a through hole, and the through hole has a stepped or inclined jaw portion in which a joint means including a packing and a pressing ring can be installed at a predetermined position. .

또한 각종 기구에 일체로 용접되어 주름관 또는 직관이 연결되는 연결부위는 파이프의 내경에 나사공을 형성한 부재를 사용하게 되는데 이것은 단턱 또는 경사턱부를 갖고 있지 않기 때문에 패킹과 압착링을 포함한 조인트수단이 설치될 수 없어 연결부위에 조인트부재를 별도로 결합하여 주름관 또는 직관을 연결하고 있다.In addition, the joint part welded to various instruments and connected to the corrugated pipe or straight pipe uses a member formed with a threaded hole in the inner diameter of the pipe. This means that the joint means including the packing and the pressing ring have no stepped or inclined jaw. Since it cannot be installed, the joint member is separately connected to the connecting portion to connect the corrugated pipe or the straight pipe.

상술한 용도로 사용되는 종래의 조인트부재는 황동 주물로 널리 제작되었으나 납성분으로 인한 유해성 논란으로 인해 최근에는 스테인레스재를 사용하여 경향을 보이고 있다.Conventional joint members used for the above-mentioned applications have been widely manufactured in brass castings, but due to the controversy of the harmfulness caused by lead components, stainless steel materials have recently been used.

그러나 납성분으로 인한 유해성 논란에서 자유로운 스테인레스재를 사용하는 경우 단턱과 경사턱부를 관통공에 형성하기 위해서는 정밀 주조 방법에 의해 조인트부재를 제작할 수 밖에 없는데 이는 제조원가의 상승은 물론 생산력 저하라는 문제를 일으키게 됨으로써 본 발명의 기술분야에 종사하는 제조업자로서는 진퇴양난에 처해 있는 상황이다.However, in the case of using the stainless steel material free from the controversy caused by the lead component, the joint member must be manufactured by the precision casting method in order to form the step and the inclined jaw in the through hole, which leads to a problem such as an increase in manufacturing cost and a decrease in productivity. As a result, a manufacturer engaged in the technical field of the present invention is in a situation of dilemma.
