본 고안은 숫나사를 내는 나사절삭기에 리이머를 연결지지대로 부설시켜 파이프의 의경 숫나사형성과 동시에 내경확공까지 절삭시킬 수 있는 리이머가 부설된 나사절삭기에 관한 것이다.The present invention relates to a screw cutter equipped with a reamer that can cut the inner diameter of the pipe at the same time as the male diameter of the pipe by laying the reamer as a connecting support to the male screw cutter.

종래에는 파이프의 첨단외경을 나사절삭기로서 숫나사를 낸후 다시 2차가공으로 리이머로서 파이프의 첨단내경을 확공시키므로서 이중작업으로 시간과 노력이 소모되었다.Conventionally, after cutting the external thread of the pipe as a screw cutter, the external thread of the pipe is expanded as a reamer by the second machining, and the time and effort are consumed by the double operation.

본 고안에서는 이와 같은 불편을 제거하고져 나사절삭용 나사절삭기의 양측에 보울트삽입공을 천공시켜 이에 대향지게 리이머의 연결봉이 삽입되어 주연에 돌설된 결림돌기로서 리이머의 위치를 조절할 수 있게 다수의 홈이 서로 깊이가 다르게 경사요철홈이 형성된 연결구가 부착된형의 연결지지대를 보울트로서 부착시켜 외경의 숫나사와 동시에 첨단내경까지 확공시킬 수 있는 것으로서 도면에 의거 상세히 설명하면 다음과 같다.The present invention eliminates this inconvenience and drills the bolt insertion hole on both sides of the screw cutting screw cutter so that the connecting rod of the reamer is inserted so as to face the stiffening protrusion at the periphery. The grooves are attached to each other at different depths. Attaching the connection support of the mold as a bolt to expand the inner diameter at the same time as the male thread of the outer diameter as described in detail according to the drawings as follows.

다이스의 내경을 조절할 수 있는 보울트(2),(3)가 상, 하로 체결되고 양측면의 나사공(4),(5)에 부착된형의 연결지지대(10) 중앙공에 리이머(12) 연결봉(13)을 삽입시켜 지지대 외부에서 스프링(15)으로 탄발되게 눌림편(16)을 부착시킨 공지의 절삭기에 있어서 연결봉이 삽입된 지지대 내측면에 다수의 홈이 각각 그 깊이가 서로 다른 경사요철홈(11)이 형성된 연결구(11)를 부착시켜 연결봉의 전부쪽 일편에 돌설된 걸림돌기(14)로서 필요길이에 맞게 다수의 경사요철홈에 결속시켜서 된 것으로 미설명부호(6)는 손잡이이다.Bolts (2) and (3) for adjusting the inner diameter of the die are fastened up and down and attached to the screw holes (4) and (5) on both sides. Support rod with insertion rod in a known cutting machine in which the pressing piece 16 is elastically attached to the spring 15 from the outside of the support by inserting the reamer 12 connecting rod 13 into the central hole of the connecting support 10 of the die. A plurality of inclined concave-convex grooves are attached to the inner side by attaching a connector 11 having a plurality of inclined concave-convex grooves 11 having different depths. It is made by binding to the groove, and reference numeral 6 is a handle.

이와 같은 구조로 된 본 고안은 다이스 양측에 보울트로 채결된형의 연결지지대(10)의 중앙연결구(11)에 스프링(15)의 탄발에 의해 홈에 걸림돌기(14)가 삽입되어 있는 연결봉(13)을 후단의 눌림편(16)으로 압압시켜 걸림돌기를 전진시켜 요철홈(11')에 이탈시킨 후 파이프직경과 첨단내경의 확공도에 따라 요철홈(11')을 정하여 연결봉의 걸림돌기(14)로 걸리도록 삽입시켜 리이머의 전, 후진 위치를 확고히 정한후 나사절삭기에 파이프를 넣고 손잡이(6)를 상, 하로 작동시키면 파이프의 외경첨단에 숫나사가 형성 되면서 동시에 내경에는 리이머에 의해 내경이 확공되는 것이다.The present invention has a structure such as bolts on both sides of the die Pressing the connecting rod 13 into which the locking projection 14 is inserted into the groove by the springing force of the spring 15 to the central connector 11 of the connecting support 10 of the type is pressed by the pressing piece 16 at the rear end. After moving forward and away from the uneven groove 11 ', the uneven groove 11' is determined according to the expansion of the pipe diameter and the inner diameter of the tip, and inserted into the catching protrusion 14 of the connecting rod. After firmly determined, insert the pipe into the screw cutter and operate the handle (6) up and down to form a male thread on the outer diameter tip of the pipe and at the same time the inner diameter is expanded by the reamer on the inner diameter.
