압착식 금속관이음쇠용 프레스공구의 스라이드 키의 구조.{STRUCTURE OF SLIDE KEY OF PRESS TOOL FOR PRESS TYPE METAL PIPE JOINT.}Structure of slide key of press tool for crimped metal pipe fitting. {STRUCTURE OF SLIDE KEY OF PRESS TOOL FOR PRESS TYPE METAL PIPE JOINT.}

본 고안은 압착식 금속관이음쇠④용 프레스공구에서, 작업 중 공구본체로부터 완전 분리됨이 없이 공구 내에 항상 조립되어 있는 상태에서, 공구의 개폐작동을 위하여 반복적 왕복 스라이드 운동을 하게 되는 스라이드 링크핀⑤ 위의 스라이드 키 홈⑥ 내에 돌출 삽입되는 스라이드 키⑦에, 공지의 기술인 스라이드 링크핀⑤ 분리 방지 기능 외에, 스라이드 링크핀⑤과의 탄성적 가압 접촉 구조를 추가로 형성하여 주므로써, 그 가압력에 의한 마찰저항의 힘으로 스라이드 링크핀⑤의 불규칙 자연 이동 방지 기능을 부여하여 공구의 작업성을 개선하는 기술이다.The present invention is a press tool for the crimped metal pipe fittings ④, on the slide link pin ⑤, which is repeatedly reciprocating for the opening and closing operation of the tool while always being assembled in the tool without being completely separated from the tool body during operation. Friction resistance due to the pressing force is provided on the slide key ⑦ protrudingly inserted into the slide key groove ⑥, in addition to the slide link pin ⑤ prevention function of the known technique, in addition to the slide link pin ⑤ prevention function. It is a technology that improves the workability of the tool by granting the function of preventing the irregular movement of the slide link pin⑤ with the force of.

상기 기술분야에서와 같은 스라이드 링크핀⑤과, 그 위의 스라이드 키 홈⑥에 삽입되는 스라이드 키⑦ 사이의 관계에서, 기존 스라이드 키⑦에 의하여, 공구의 개폐작동시 스라이드 링크핀⑤을 공구본체로부터 완전히 분리시키지 않고 작업은 가능하게 되지만, 공구의 작업 중 스라이드 링크핀⑤의 자중에 의한 자연 락하현상 등, 불규칙한 자연 스라이드 이동의 규제수단이 없어 이로 인한 조작상의 불편과 작업성 저하의 문제가 있어 왔다.In the relation between the slide link pin ⑤ as in the above technical field and the slide key ⑦ inserted into the slide key groove ⑥ above, the slide link pin ⑤ is removed from the tool body by the existing slide key ⑦ during the opening and closing operation of the tool. Although it is possible to work without being completely separated, there is no control means for irregular natural slide movement, such as the natural lock-down phenomenon caused by the weight of the slide link pin ⑤ during the operation of the tool, which has caused problems of operational inconvenience and deterioration of workability. .

상기 배경기술에서와 같이 프레스공구의 개폐작동시 스라이드 링크핀⑤의 불규칙한 자연 스라이드 이동으로 인한 공구의 개폐조작 상의 불편과 작업성 저하의 문제를 해결하는 것이 과제이다As in the background art, it is a problem to solve the problem of the inconvenience of opening and closing of the tool and the deterioration of workability due to the irregular natural slide movement of the slide link pin ⑤ during the opening and closing operation of the press tool.

유압시린더⑬의 롯드커버⑩ 위에 설치되는 스라이드 키⑦의 배후에 도 5에서와 같이 스프링⑧ 또는 고무 등 탄성체를 설치하여 스라이드 키⑦가 그 탄력에 의하여 스라이드 링크핀⑤과 서로 가압 접촉되는 구조로 구성하는 것을 수단으로 한다.In the structure behind the slide key ⑦ installed on the rod cover ⑬ of the hydraulic cylinder ⑬ as shown in FIG. 5, an elastic body such as a spring ⑧ or rubber is installed so that the slide key ⑦ is press-contacted with the slide link pin ⑤ by its elasticity. It is a means to comprise.

상기 해결수단에 의하여 스라이드 링크핀⑤과 스라이드 키⑦ 사이에 발생되는 탄성적 가압력에 의한 마찰저항으로 스라이드 링크핀⑤의 불규칙한 자연 이동이 방지되고 그 모든 이동이 작업자의 의사에 의하여만 이루어지게 되므로 작업성 향상의 효과가 있게 된다Because of the frictional resistance caused by the elastic pressing force generated between the slide link pin ⑤ and the slide key ⑦ by the solution means that the irregular natural movement of the slide link pin ⑤ is prevented and all the movement is made only by the operator's intention It becomes effective of sex improvement

서로 대향(對向) 이동되는 어퍼죠①와 로워죠② 위에 각 두개식 스라이드 이동 가능하도록 설치된 합계 네개의 압착다이③를 역방사상으로 수렴 이동되도록 상기 죠①, ②를 서로 유압시린더⑬의 피스턴롯드⑫로 가압하여 압착식 관이음쇠④를 압착체결하는 프레스공구에 있어서, 압착을 위하여 프레스공구 내에 관이음쇠④를 장착하고, 압착 후 관이음쇠④로부터 공구를 분리시키기 위하여 공구의 개폐작동을 하게 되며, 이 개폐작동을 위하여 도 1, 2, 4에서와 같이 공구개폐용의 스라이드 링크핀⑤을 탈착조작하고 어퍼죠①를 힌지핀⑪을 중심으로 회전시켜 개폐가 이루어지게 된다. 이 과정에서 작업성을 저하시키는 스라이드 링크핀⑤의 불규칙 자연 스라이드 이동을 저지하기 위하여 스라이드 링크핀⑤ 위에 형성되어 있는 스라이드 키 홈⑥ 내에 삽입되도록 유압시린더⑬의 롯드커버⑩ 위에 설치되는 스라이드 키⑦의 배후에 도 5에서와 같이 스프링⑧ 또는 고무 등 탄성체를 설치하여 그 탄성체의 가압력으로 스라이드 키⑦와 스라이드 링크핀⑤ 사이에 마찰저항을 발생시키는 것으로 실시된다The pistons of the hydraulic cylinder 서로 are moved to the upper cylinder ① and the lower roller ② which are opposed to each other, so that the four compression dies ③ installed in the two radial slides on the upper jaw can converge in the reverse direction. In the press tool that press-fits the crimped pipe fitting ④ by pressing with rod 관, the pipe fitting ④ is mounted in the press tool for crimping, and the tool is opened and closed to separate the tool from the pipe fitting ④ after crimping. For this opening and closing operation, as shown in FIGS. 1, 2 and 4, the sliding link pin ⑤ for opening and closing the tool is detached and operated by rotating the upper jaw ① about the hinge pin ⑪. Slide key ⑦ is installed on the rod cover 유압 of the hydraulic cylinder 되도록 to be inserted into the slide key groove ⑥ formed on the slide link pin ⑤ to prevent the irregular natural slide movement of the slide link pin ⑤ to reduce workability in this process 5 is provided with an elastic body such as a spring ⑧ or rubber as shown in FIG. 5 to generate a frictional resistance between the slide key ⑦ and the slide link pin ⑤ under the pressing force of the elastic body.

여기서 스라이드 키 홈⑥의 양단 깊이를 서로 다르게 하여 내면에 경사면을 형성하면 더 효과적 결과를 얻을 수 있다.Here, a more effective result can be obtained by forming inclined surfaces on the inner surface with different depths of the slide key grooves ⑥.
