And a horizontal drive cylinder 44 installed at the side of the main body 40 to provide power to move from side to side.

상기 본체(40)는 내부에 공간부가 구비된 직육면체로서, 작업대(2)에 수평으로 설치된 가이드레일(41)에 결합되어 좌우로 이동이 가능하도록 한 것으로, 본체(40)와 가이드레일(41)은 통상의 LM가이드를 이용한 결합방식이 사용된다.The main body 40 is a rectangular parallelepiped having a space therein, which is coupled to the guide rail 41 horizontally installed on the worktable 2 to move left and right, and the main body 40 and the guide rail 41. The coupling method using a conventional LM guide is used.

상기 지지부(42)는, 본체(40)의 내측 하부에 설치되며, 소정의 사잇각(θ)을 두고 두개의 가지부재가 대략 "∧" 형상으로 배치되어 형성된 써포터(422)와, 상기 가지부재의 하부 양끝단에 베어링으로 결합되어 회전가능하게 설치된 복수개의 롤러(43)로 구성된다. The support part 42 is installed on the inner lower portion of the main body 40, and the supporter 422 formed by arranging two branch members in a substantially "∧" shape at a predetermined angle θ, and the branch members. It is composed of a plurality of rollers 43 rotatably coupled to bearings at both ends of the lower part.

The arm 65 may be rotated clockwise or counterclockwise by the indentation operation of the cylinder rod 674, and the cutting edge 66 installed on the arm 65 may be clockwise or counterclockwise. It can be contacted and released from the sheath 120 of the steel pipe 100 while turning.

이와 같이 구성된 본 발명의 결합 및 작동관계를 설명한다.The combination and operation relationship of the present invention configured as described above will be described.

작업대(2)의 하부에는 회전장치(200)가 설치되고, 상부에는 본체(40)가 설치되며, 본체(40)는 작업대(2)에 수평으로 설치된 가이드레일(41)에 결합된다.The rotary device 200 is installed at the lower part of the work table 2, the main body 40 is installed at the upper part, the main body 40 is coupled to the guide rail 41 horizontally installed on the work table (2).

본체(40)의 측방에는 수평구동실린더(44)가 설치되고, 하부에 써포터(422)가 설치되며, 상기 써포터(422)의 가지부재에는 각기 롤러(43)가 회전가능하게 설치되어 지지부(42)가 형성된다.A horizontal drive cylinder 44 is installed at the side of the main body 40, and a supporter 422 is installed at a lower portion thereof, and rollers 43 are respectively rotatably installed at the branch members of the supporter 422 to support the support 42. ) Is formed.

한편, 본체(40)의 내측면에 수직의 승강레일(61)이 설치되고, 이 승강레일(61)에 결합되도록 본체(40) 내에 함체(62)가 설치되며, 함체(62) 내부에는 전방에서 후방을 향하도록 수평의 전후이동레일(622)이 설치되며, 상기 전후이동레일(622)에 블럭(63)이 결합된다.On the other hand, the vertical lifting rail 61 is installed on the inner surface of the main body 40, the housing 62 is installed in the main body 40 to be coupled to the lifting rail 61, the front inside the housing 62 A horizontal forward and backward rail 622 is installed to face rearward, and the block 63 is coupled to the forward and backward rail 622.

그리고, 블럭(63)의 하부에는 조인트부싱(64)을 갖는 아암(65)이 힌지결합되고, 전기 아암(65)의 브래킷(652)에 절삭날(66)이 하부를 향하도록 설치된다.An arm 65 having a joint bushing 64 is hinged to the lower portion of the block 63, and the cutting edge 66 is installed on the bracket 652 of the electric arm 65 so as to face downward.

이후, 상기 아암(65)의 끝단과 블럭(63)을 연결하는 회전실린더(67)가 설치 된다.Thereafter, a rotary cylinder 67 is installed to connect the end of the arm 65 and the block 63.

즉, 강관(100)의 직경에 따라 수평구동실린더(44)가 이동하면서 정중앙을 정확하게 찾을 수 있는 것이다.That is, while the horizontal drive cylinder 44 is moved in accordance with the diameter of the steel pipe 100 is to find the exact center.

상기 회전실린더(67)의 실린더로드(674)가 인출되어 아암(65)을 반시계방향으로 회전시키면, 절삭날(66)이 피복(120)에 삽입된다.When the cylinder rod 674 of the rotary cylinder 67 is pulled out and the arm 65 is rotated counterclockwise, the cutting edge 66 is inserted into the coating 120.

이때, 아암(65)의 회전각도의 제어에 따라 절삭날(66)의 삽입 깊이를 제어할 수 있다.At this time, the insertion depth of the cutting edge 66 can be controlled according to the control of the rotation angle of the arm 65.

이렇게 절삭날(66)이 피복(120)에 삽입되면 강관(100)의 자전에 의해 피복(120)이 깍여지면서 탈피된다.When the cutting edge 66 is inserted into the coating 120 in this manner, the coating 120 is scraped off by the rotation of the steel pipe 100.

전술한 아암(65)의 회전과 동시에 전후구동실린더(632)의 작동에 의해 블럭(63)이 서서히 후진하도록 함으로써, 절삭되는 폭이 점차 확대된다.The width to be cut is gradually enlarged by allowing the block 63 to retreat gradually by the operation of the front and rear drive cylinder 632 simultaneously with the rotation of the arm 65 described above.

또한, 피복(120)이 절삭되는 폭은 전후구동실린더(632)의 작동 정도에 따라 제어된다.In addition, the width at which the sheath 120 is cut is controlled according to the degree of operation of the front and rear drive cylinder 632.

즉, 상기 절삭순서를 정리해보면, 회전실린더(67)의 반시계방향 회전에 의해 절삭날(66)이 반시계방향으로 회전되어 피복(120)에 삽입되는 단계와, 전후구동실린더(632)의 작동에 의해 절삭날(66)이 후진하는 단계와, 회전실린더(67)의 시계방향의 회전에 의해 절삭날(66)이 시계방향으로 회전되어 피복(120)으로부터 이격되는 단계와, 전후구동실린더(632)의 작동에 의해 절삭날(66)이 전진하여 원위치되는 단계를 순차적으로 수행하게 된다.That is, the cutting sequence is summarized, the cutting edge 66 is rotated counterclockwise by the counterclockwise rotation of the rotary cylinder 67 is inserted into the coating 120, and the front and rear driving cylinder 632 The cutting edge 66 is reversed by the operation, the cutting edge 66 is rotated clockwise by the clockwise rotation of the rotary cylinder 67, and is spaced apart from the sheath 120; By the operation of 632, the cutting edge 66 is advanced to perform the step of home position sequentially.

전술한 수평구동실린더(44), 승강실린더(624), 전후구동실린더(632), 회전실린더의 움직임은 제어부(미도시)를 통해 사용자가 작업전에 필요한 치수로 셋팅할 수 있음은 물론이다.The above-described horizontal drive cylinder 44, the lifting cylinder 624, the front and rear drive cylinder 632, the rotation of the cylinder can be set to the dimensions necessary before the user through the control unit (not shown).
