작업대(11) 위에 다수개의 로울러(13-1)(23-1)를 각각 갖는 구동축(13)과 피구동축(23)을 가지며, 상기 구동축(13) 및 피구동축(23)의 다수개의 로울러(13-1)(23-1) 위에 파이프(51)를 올려놓고, 구동축(13) 일측에 체인기어(15)와 연결된 모터(17)를 구동하여, 구동축(13)을 구동하여 파이프(51)를 구동시킬 때, 구동되는 파이프(51)의 회전력에 의해, 다수개의 로울러(23-1)를 결합한 피구동축(23)은 구동하게 된다.A drive shaft 13 and a driven shaft 23 each having a plurality of rollers 13-1 and 23-1 on the worktable 11, and a plurality of rollers of the drive shaft 13 and the driven shaft 23 ( The pipe 51 is placed on the 13-1 and 23-1, and the motor 17 connected to the chain gear 15 is driven on one side of the drive shaft 13, and the drive shaft 13 is driven to drive the pipe 51. In driving the driven shaft, the driven shaft 23 to which the plurality of rollers 23-1 are coupled is driven by the rotational force of the driven pipe 51.

이와 같은 피구동축(23)은 구동축(13)과의 간격을 임의로 조절할 수 있는 바, 피구동축(23) 일측의 작동봉(31)을 핸들(32)로 회전시킬 때, 상기 피구동축(23)을 지지하는 피구동축지지구(24)는 이동안내구(26)를 따라, 전후로 이동되어, 피구동축(23)을 이동시켜 구동축(13)과 피구동축(23)과의 거리를 조절하게 된다.The driven shaft 23 can arbitrarily adjust the distance from the drive shaft 13, and when the operating rod 31 of one side of the driven shaft 23 is rotated by the handle 32, the driven shaft 23 The driven shaft support 24 supporting the moving shaft is moved back and forth along the movement guide 26 to move the driven shaft 23 to adjust the distance between the drive shaft 13 and the driven shaft 23.

상기 피구동축지지구(24) 하방에는 나사식으로 결합하는 축기어(27)를 가지며 축기어(27) 단부에는 제1베벨기어(29)를 가지며, 상기 제1베벨기어(29)는 작동봉(31)에 결합한 제2베벨기어(33)와 맞물려져 작동봉(31) 단부의 핸들(32)로 작동봉(31)을 회전시킬 경우 서로 맞물린 제1,제2베벨기어(29)(33)에 의해 축기어(27)는 회전되어, 축기어(27)에 나사식으로 결합된 피구동축지지구(24)를 이동안내구(26)를 따라 전,후로 이동시켜, 구동축(13)과 피구동축(23) 사이를 조절하게 되는 것이다.The driven shaft support 24 has a shaft gear 27 to be screwed to the lower side of the driven shaft support 24, the end of the shaft gear 27 has a first bevel gear 29, the first bevel gear 29 is an operating rod The first and second bevel gears 29 and 33 engaged with each other when engaged with the second bevel gear 33 coupled to (31) to rotate the operating rod 31 by the handle 32 at the end of the operating rod 31. The shaft gear 27 is rotated by) to move the driven shaft support 24, which is screwed to the shaft gear 27, back and forth along the movement guide 26, the drive shaft 13 and It is to be adjusted between the driven shaft (23).

상기와 같이 피구동축(23)과 구동축(13)과의 간격을 조절함에 있어 소구경파이프인 경우 구동축(13)과 피구동축(23) 간격을 좁게 조절하며, 대구경파이프인 경우 구동축(13)과 피구동축(23) 간격을 넓게 조절하여, 어떤 직경의 파이프라도 용이하게 회전시킬 수 있게 된다.As described above, in adjusting the distance between the driven shaft 23 and the drive shaft 13, the distance between the drive shaft 13 and the driven shaft 23 is narrowly adjusted in the case of the small-diameter pipe, and the drive shaft 13 and the large-diameter pipe. By controlling the distance of the driven shaft 23 to be wide, it is possible to easily rotate any diameter pipe.

이와 같이 구동축(13)과 피구동축(23)에 결합된 각각의 로울러(13-1)(23-1) 위에 얹혀져서 회전하는 파이프(51)는 절단토치(43)에 의해 절단되는 바,Thus, the pipe 51 mounted on the rollers 13-1 and 23-1 coupled to the drive shaft 13 and the driven shaft 23 and rotating is cut by the cutting torch 43,

상기 절단토치(43)는 산소절단토치나 프라즈마절단토치를 사용하며, 필요에 따라서는 토치지지대(44)에 그라인더를 장착하여, 절단된 파이프 단면을 가공하게 된다.The cutting torch 43 uses an oxygen cutting torch or a plasma cutting torch, and, if necessary, mounts a grinder on the torch support 44 to process the cut pipe section.

이와 같은 절단토치(43)는 작업대(11) 위의 레일(41) 위를 따라 주행하는 토치이송대(42)에 결합되어지며, 상기 토치이송대(42) 일측에는 기계조작패널(45)을 가지며, 토치이송대 내측에는 토치이송대를 레일에 따라 주행시키는 구동기구를 가지며, 상기 토치이송대(42)에는 절단토치(43)를 고정하는 토치지지대(44)와, 상기 토치지지대(44)를 상하로 이송하여 높이를 조절하는 높이조절수단(46)을 갖게 된다.This cutting torch 43 is coupled to the torch carriage 42 running along the rail 41 on the worktable 11, and has a machine operation panel 45 on one side of the torch carriage 42. The torch feeder has a drive mechanism for driving the torch feeder along the rail, and the torch support 42 carries the torch support 44 for fixing the cutting torch 43 and the torch support 44 up and down. It has a height adjusting means 46 for adjusting the height.

이와 같은 본 발명은 파이프를 회전시켜 파이프를 원주 방향(세로방향)으로 절단하게 되나, 구동축(13)을 회전시키지 않고 정지시킨 상태로, 레일(41)상의 토치이송대(42)를 이동시킬 경우, 파이프를 길이 방향으로도 절단이 가능하므로 원하는 형태로 파이프를 절단할 수 있게 된다.In the present invention, the pipe is rotated to cut the pipe in the circumferential direction (vertical direction), but when the torch feeder 42 on the rail 41 is moved in a state of being stopped without rotating the drive shaft 13, The pipe can also be cut in the longitudinal direction, allowing the pipe to be cut in the desired shape.

또한 높이조절수단(46)에는 파이프의 곡면상태를 감지하는 파이프곡면감지센서(47)를 가져, 진원 상태가 아닌 타원형으로 표면이 변형된 파이프인 경우에도, 절단토치(43)를 지지하는 토치지지대(44)의 높낮이를 높이조절수단(46)으로 자동으로 조절하여 절단토치(43)가 절단하는 파이프(51)의 간격을 항상 일정하게 조절하여 균일한 절단면으로 파이프가 절단되도록 하였다.In addition, the height adjusting means 46 has a pipe curved surface sensor 47 for detecting a curved state of the pipe, even if the pipe is deformed in the shape of an ellipse rather than a round shape, torch support for supporting the cutting torch 43 The height of the 44 is automatically adjusted by the height adjusting means 46 so that the interval of the pipe 51 cut by the cutting torch 43 is always adjusted constantly so that the pipe is cut into a uniform cutting surface.

또한 토치지지대(44)에 고정되는 절단토치(43)를 파이프(51)의 면과 직각방향이 아닌 경사진 방향으로 고정할 경우 파이프 절단 단면은 균일한 경사면으로 파이프가 절단되어 지게 된다.In addition, when the cutting torch 43 fixed to the torch support 44 is fixed in an inclined direction rather than at right angles to the surface of the pipe 51, the pipe is cut in a uniform cross section of the pipe.

도4 도1의 A부분 확대도.4 is an enlarged view of portion A of FIG.

도5 본 발명에 있어 구동축과 피구동축의 거리가 벌어져 대구경파이프를 절단하는 것을 보인 사용상태 단면도.Fig. 5 is a cross-sectional view of the use state in which the distance between the drive shaft and the driven shaft is widened to cut a large diameter pipe in the present invention.

도6 본 발명에 있어 구동축과 피구동축의 거리가 근접되어 소구경파이프를 절단하는 것을 보인 사용상태 단면도. Figure 6 is a cross-sectional view of the use state showing that the distance between the drive shaft and the driven shaft is close in the present invention to cut a small diameter pipe.
