A cutting device of pipe

본 고안은 비교적 큰 구경의 파이프를 절단하는 파이프 절단장치에 관한 것으로, 특히, 컷팅기가 부착되어 파이프 외주면을 타고 연직으로 이동할 수 있게 하는 가이드카라와 그 이동을 돕는 카라부착지그로 형성되어 파이프의 외주면을 돌며 절단하는 대구경 파이프 절단장치이다. The present invention relates to a pipe cutting device for cutting a pipe having a relatively large diameter, and in particular, a cutting collar is attached to the guide collar to move vertically on the outer peripheral surface of the pipe and the collar attached jig to assist the movement of the outer peripheral surface of the pipe This is a large diameter pipe cutting device for cutting round. 그러나 종래에 사용된 파이프 절단방법은 사람의 눈과 손을 이용한 수동의 방식을 취하고 있기에 표시된 선에서 조금씩 벗어날 소지도 있으며, 비스듬한 각도로 파이프를 절단하게 되면 간혹 컷팅날이 튀어 상해를 입기도 한다. However, the pipe cutting method used in the related art may be slightly out of the marked line because it takes a manual method using a human eye and a hand, and when the pipe is cut at an oblique angle, the cutting blade sometimes pops up and is injured. 이에 반하여 본 고안의 파이프 절단장치는 비교적 대구경의 금속파이프를 절단함에 있어서, 아주 간단한 구조지만 연직으로 정확하게 커팅할 수 있는 유용한 고안이다. On the contrary, the pipe cutting device of the present invention is a useful design that can cut a very large diameter metal pipe in a very simple structure but can be accurately cut vertically. 또한 본 고안은 핸드컷팅기를 슬라이딩롤을 통해 파이프 외주면에 수직으로 서서히 이동시킬 수 있기에 날이 튀어 작업자가 상해를 입는 경우를 최소화시킨다. In addition, the present invention minimizes the case of worker injury by splashing the blade because it can be moved slowly vertically to the outer peripheral surface of the pipe through the sliding roll.

Pipe cutting machine

The present invention relates to a pipe cutter capable of cutting a pipe regardless of the diameter of the pipe, maximizing work efficiency by remarkably reducing a pipe cutting time; and providing functionality such as accurately cutting the pipe in a perpendicular direction. The pipe cutter comprises a clamping driving unit and a pipe cutting unit. The clamping driving unit is installed on the upper part of a body in order to rotate the pipe supplied in an axial direction by a pipe supply unit installed on the rear part of the body in a clamping state. The pipe cutting unit includes a pipe which is rotated in the clamping state by the clamping driving unit and a rotary cutter cutting the pipe by moving to the pipe in the perpendicular direction.

Carrying along light steel pipe cutter

A portable lightweight steel pipe cutter is provided to easily cut a steel pipe with fixed ends or a long steel pipe, by pushing the steel pipe in a lateral direction. A portable lightweight steel pipe cutter comprises a holding unit(100), a cutting unit(200), a driving motor(300), and a power transmission unit(400). The holding unit firmly holds a steel pipe to be cut. The cutting unit is arranged coaxially with the holding unit, and includes a cutter which rotates along a periphery of the steel pipe and cuts the steel pipe through plastic deformation process. The driving motor supplies power for rotating the cutting unit. The power transmission unit is coaxially arranged between the holding unit and the cutting unit, and permits the cutting unit to rotate by decelerating power supplied from the driving motor and transmitting decelerated power to the cutting unit.

Apparatus for cutting steel pipe

PURPOSE: A steel pipe cutting apparatus is provided to reduce the time of cutting work by employing an automatic hydraulic cutting method. CONSTITUTION: A steel pipe cutting apparatus(100) comprises a rotary unit(110), a guide unit(120), a hydraulic unit(130), and a cutting unit(140). The rotary unit includes a housing(111) and a pair of rollers(112) which are rotated with a motor to rotate a steel pipe. The guide unit has a frame(121) and a hook(122) which is locked on a holding protrusion(115) to fix the frame to the housing. The hydraulic unit comprises a hydraulic cylinder(131), an oil tank for storing oil provided to the hydraulic cylinder, and a push bar(132) which supplies the oil from the oil tank to the hydraulic cylinder by vertical pumping. The cutting unit comprises a base plate(141), a cutter which contacts and cuts a steel pipe when the blade plate descends, and a contact bearing which presses the steel pipe downward by interlocking with the rotated steel pipe.

A powered tool for tube cutting and treating

본 발명은 절단용 튜브를 수용하기 위한 개방 단부와 동력원을 구비하고 튜브 등을 절단하고 처리하기 위한 동력 공구에 관한 것이다. 여기에는 절단하는 동안 튜브 주위에서 회전하기 위한 롤러와 튜브 커터가 있다. 공구 하우징은 커터와 롤러 및 다른 속도로 회전할 수 있는 2개의 기어 열을 둘러싼다. 이 기어열 중 하나의 기어열은 공구를 회전시키는 구동을 야기하고 이 기어열 중 다른 기어열은 튜브 절단을 야기한다. 회전 구동은 절단될 그 다음 튜브에 개방 단부를 설정 및 제공함과 동시에 시작 위치에 커터와 롤러를 설정하기 위해 역회전될 수 있다. 회전 기어는 또한 튜브를 처리하기 위한 2개의 동력 분리 수단(power-take-offs)을 구동한다. The present invention relates to a power tool having an open end and a power source for receiving a cutting tube and for cutting and processing a tube or the like. There are rollers and tube cutters for rotating around the tube during cutting. The tool housing surrounds a cutter and roller and two gear trains that can rotate at different speeds. One of the gear trains causes the drive to rotate the tool and the other gear train causes the tube cutting. Rotational drive can be reversed to set the cutter and roller in the starting position while setting and providing an open end to the next tube to be cut. The rotary gear also drives two power-take-offs for processing the tube.
