본 고안은 압착식 금속관이음쇠⑬용 압착공구의 스라이드 링크핀①의 장착구조에 관한 것으로, 매압착 작업시마다 링크핀을 공구로부터 분리시켜, 그 탈착을 반복해야 하는 현재의 탈착링크핀의 탈착작업으로 인한 작업능율의 저하, 그리고 분리된 탈착링크핀의 관리,보관과 분실위험 등의 문제를 해결할 수 있는 새로운 기술로써 본 고안의 스라이드 링크핀①의 장착구조에 관한 기술을 그해당분야로 한다.The present invention relates to the mounting structure of the slide link pin ① of the crimping tool for crimping metal pipe fittings ,, and it is necessary to remove the link pin from the tool at every crimping operation and to remove the link pin. The technology related to the mounting structure of the slide link pin ① of the present invention is a new technology that can solve the problems such as deterioration of work efficiency and management of separated detachable link pin, storage and risk of loss.

현재까지의 압착식 금속관이음쇠⑬용 압착공구에서 유압시린더⑦와 링크프레이트④를 연결시키는 링크핀은 탈착식(脫着式)으로 하여, 작업중 매압착시 마다, 공구에 관이음쇠⑬를 삽입하거나, 압착후 관이음쇠⑬를 분리하기 위하여 그 탈착링크핀을 공구로부터 완전히 분리시켰다가 다시 공구의 링크핀공⑤ 및 유압시린더⑦의 롯드커버⑧에 삽입하는 방법으로 사용되어 왔고, 분리된 탈착링크핀은 세선(細線)의 와이어(WIRE) 등으로 공구에 연결시켜 보관하는 구조로 되어 있었으나, 이와 같은 탈착링크핀의 사용 및 관리구조로서는, 세심한 주의를 요하는 링크핀 삽입의 반복작업으로 인한 작업능율의 저하, 그리고 분리된 탈착링크핀의 보관관리상의 불편함과 연결와이어 등의 파단에 따른 분실위험 등의 문제가 있어 왔다.The link pin connecting hydraulic cylinder ⑦ and link plate ④ in the crimping tool for crimping metal pipe fitting ⑬ until now is detachable, and the pipe fitting 에 is inserted into the tool at every press during operation. In order to separate the pipe fitting 후 after crimping, the detachable link pin has been completely removed from the tool and then inserted into the link pin hole ⑤ of the tool and the rod cover ⑧ of the hydraulic cylinder ⑦. Although it was designed to be connected to a tool by a wire such as a thin wire and stored, the use and management structure of such a detachable link pin can be used to improve the work efficiency due to the repeated work of link pin insertion requiring careful attention. There have been problems such as deterioration, inconvenience in storage management of the detachable link pins, and the risk of loss due to breakage of the connection wire.

상기 배경기술에서와 같이 현재 사용되고 있는 탈착링크핀의 작업시 반복되는 탈착조작에 따른 작업능율의 저하, 그리고 분리된 탈착링크핀의 보관, 관리상의 불편과 분실위험 등의 문제가 해결하고자 하는 과제이다.As in the background art, problems such as deterioration of work efficiency due to repeated detachable operation and storage of separated detachable link pins, management inconvenience, and risk of loss are solved. .

해결수단은, 종전의 상기 탈착식 링크핀 장착구조를 스라이드식으로 개선하여, 그 스라이드 링크핀①이 작업중 공구로부터 완전분리되지 않는 상태에서, 관이음쇠⑬의 압착공구 내로의 삽입 및 압착공구로부터의 분리작업이 가능하도록 개선하는 것이다.The solution is a slide-type improvement of the conventional detachable link pin mounting structure, and the fitting of the pipe fitting ⑬ into the crimping tool and the detachment from the crimping tool without the slide link pin ① being completely detached from the tool during operation. It's about making things work.

위의 해결수단에서와 같이, 압착작업과정에서 압착공구 본체로부터 분리되지 않는 스라이드 링크핀①의 장착구조에 의하여, 상기 해결과제와 같은 반복적 링크핀의 재삽입으로 인한 작업능율의 저하, 그리고 링크핀의 보관, 관리상의 불편과, 작업중 링크핀의 분실사고 등의 문제를 모두 해결하는 효과를 얻을 수 있게 된다.As in the above solution, due to the mounting structure of the slide link pin ① that is not separated from the crimping tool body during the crimping operation, the work rate decreases due to the reinsertion of the repetitive link pin as in the above problem, and the link pin It is possible to obtain the effect of solving all the inconveniences of storage, maintenance, and the loss of link pins during operation.

본 고안의 실시를 위하여, 각각 쌍(

Figure 112008501803571-utm00002
)으로 되어 있는 압착공구 좌우양측의 링크프레이트④에서 각한개식의 링크핀공⑤ 내에 스라이드 키③를 고정 장착시키 고, 링크핀공⑤ 내로 삽입되는 스라이드 링크핀① 위에는 스라이드 링크핀①의 양단부로부터 각각 일정거리의 간격을 두고 있는 두개의 위치를 양단으로 하여, 축방향(軸方向)으로 형성되는 스라이드 키홈②, 또는, 스토퍼볼트⑥나 별도의 고정키로 그 양단이 막혀지는 스라이드 키홈②을 형성하여, 상기 스라이드 키③와 조합시키므로써, 스라이드 링크핀①이 링크핀공⑤ 내로부터 완전분리되지 않고 일정거리의 스라이드 이동만으로 압착공구의 관이음쇠⑬ 압착공정이 완료될 수 있게 된다.For the implementation of the present invention, each pair (
Figure 112008501803571-utm00002
The slide plate ③ is fixedly mounted in the link pin hole ⑤ on the right and left link plates ④ of each side of the crimping tool. With the two positions spaced apart at both ends, a slide key groove ② formed in the axial direction or a stopper bolt ⑥ or a slide key groove ② whose ends are blocked by a separate fixing key are formed. By combining with the key ③, the slide link pin ① is not completely separated from the link pin hole ⑤, and the crimping process of the pipe fitting 관 of the crimping tool can be completed only by moving the slide at a certain distance.

이때 상기 스라이드 링크핀①을 작업중 필요위치에서 정지시켜 두기 위하여는, 도 6에서와 같이 금속제의 스프링볼⑭과 볼홈⑮ 장치가 편리하고 여기서 금속제 스프링볼⑭을 고무재질 등의 탄성체로 할 경우 볼홈⑮을 사용하지 않아도 탄성체와 스라이드 링크핀① 몸체사이의 가압접촉에 의한 마찰력에 의하여 스라이드 링크핀①을 필요위치에 정지시킬 수 있다.At this time, in order to stop the slide link pin ① at a necessary position during operation, as shown in Figure 6, the metal spring ball and ball groove device is convenient, where the metal spring ball ball is made of an elastic material such as rubber material ball groove ⑮ Even without using, it is possible to stop the slide link pin ① at the required position by the frictional force by the pressure contact between the elastic body and the slide link pin ① body.
