Description

Pipe cutting device {omitted}

본 발명은 파이프를 물어주는 클램프 수단의 한쪽에 핸드 커터기가 설치되는 브라케트를 구비하여 커터기 또는 클램프 수단을 회전시키면 상기 핸드 커터기가 파이프의 외주면을 따라 돌면서 절단작업이 이루어짐으로써 정밀한 작업이 가능하도록 한 파이프 절단장치에 관한 것이다.The present invention is equipped with a bracket for installing a hand cutter on one side of the clamp means for burying the pipe, so that when the cutter or clamp means is rotated, the cutting operation is performed as the hand cutter rotates along the outer circumferential surface of the pipe to enable precise work. It relates to a pipe cutting device.

종래의 파이프 절단장치는 베이스에 파이프를 고정시키는 클램프가 설치되고 이 베이스의 한쪽에는 커터를 갖는 회동부재를 힌지 결합하여 파이프를 클램프에 고정시키고 회동부재를 회동시켜 절단하였으나 파이프의 직경이 커터보다 큰 경우에는 파이프의 한쪽을 절단한후 작업을 중단하고 파이프를 회전시켜야 하기때문에 작업능률이 저하될 뿐만 아니라 절단장치의 자중이 크기 때문에 이동이 어려운 문제점이 있었다.In the conventional pipe cutting device, a clamp for fixing a pipe is installed at a base, and one side of the base is hinged to a rotating member having a cutter to fix the pipe to the clamp, and the rotating member is cut by rotating the pipe. In this case, since the work must be stopped after the pipe is cut and the pipe is rotated, work efficiency is not only lowered, but also because the weight of the cutting device is large, the movement is difficult.

또한 구동모터에 의해 고속 회전되는 커터를 갖는 핸드 커터기가 사용되기도 하나 이것은 파이프에 대하여 커터를 일정한 각도로 유지하기 어렵기 때문에 숙련공이라고 하더라도 절단면이 고르지 않고 안전사고의 위험이 높은 문제점이 있었다.In addition, although a hand cutter having a cutter rotated at a high speed by a driving motor is used, it is difficult to maintain the cutter at a constant angle with respect to the pipe, so even a skilled worker has a problem of uneven cutting surface and high risk of safety accident.

본 발명이 해결하고자 하는 과제는 파이프를 물어주는 클램프 수단의 한쪽에 핸드 커터기가 설치되는 브라켓트를 구비하여 상기 핸드 커터기가 파이프의 외주면을 따라 돌면서 절단 작업이 이루어질 수 있게 함으로써 정밀한 절단이 가능하도록 한 파이프 절단장치를 제공하기 위한 것이다.The problem to be solved by the present invention is a pipe having a hand cutter is installed on one side of the clamp means for asking the pipe so that the cutting operation can be made while the hand cutter rotates along the outer circumferential surface of the pipe to enable precise cutting To provide a cutting device.

It is built between the 2nd, 3rd member 20, 60.

도 4 내지 도 5는 본 발명의 다른 실시예를 보인 도면으로써 이것은 도시된 바와 같이 상기 제 1,2,3 지지부재(10)(20)(60)과 잠금부재(40)을 반원 모양으로 제작하여 한쪽을 힌지 결합하여서 된 것이다.4 to 5 is a view showing another embodiment of the present invention, as shown, the first, second, third support members 10, 20, 60 and the locking member 40 manufactured in a semicircular shape By hinge to one side.

이 경우 반원 모양의 한쪽 잠금부재에는 돌출부(44)를 다른쪽 잠금부재에는 상기 돌출부(44)가 끼워지는 홈부(45)를 형성하는 것이 바람직하다. In this case, it is preferable to form the groove part 45 into which the protrusion part 44 is fitted in the locking member of the semicircle shape, and the protrusion part 44 in the other locking member.

또한 반원 모양의 상기 제 1,2 지지부재(10)(20)는 도 6에 도시된 바와 같이 일체로 제작될 수 있으며 제 1,2 지지부재(10)(20)가 힌지부(24)를 중심으로 벌어지는 범위가 제한되는 경우 회전부재(30)의 끼움돌부(31)를 끼움홈(12)(23)에 끼운후 힌지부(25)를 결합하는 방법으로 조립한다.In addition, the semi-circular first and second support members 10 and 20 may be integrally manufactured as shown in FIG. 6, and the first and second support members 10 and 20 may be hinge parts 24. If the range that is open to the center is limited by fitting the fitting protrusion 31 of the rotating member 30 to the fitting groove 12, 23 and then assembled by the hinge 25 combined.

반원모양의 상기 제 1,2,3 지지부재(10)(20)(60)는 제 1,2 볼트(91)(93)에 의해 결합되어 힌지부(25)를 중심으로 벌리지고 오므려지게 된다.The semi-circular first, second, third support members 10, 20, 60 are joined by the first, second, and second bolts 91, 93 so as to be spread and retracted about the hinge portion 25. do.

이하 본 발명의 절단장치에 의해 원형 또는 사각 단면의 파이프가 절단되는 과정을 다른 실시예에 의거 상세히 설명한다.Hereinafter, a process of cutting a pipe having a circular or square cross section by the cutting device of the present invention will be described in detail based on another embodiment.

도 5에 도시된 바와 같이 지지부재(10)(20)(60)와 잠금부재(40)를 힌지부(25)를 중심으로 회동시켜 벌려준 상태에서 파이프(110)를 끼워 넣고 힌지부(25)를 중심으로 회동시켜 도 7에 도시된 바와 같이 지지부재(10)(20)(60)와 잠금부재(40)가 원형이 되도록 한후 커터날(101)이 절단 위치에 놓이도록 파이프(110)의 위치를 조절한다.As shown in FIG. 5, the support members 10, 20, 60 and the locking member 40 are rotated about the hinge portion 25 to open the pipe 110 in the open state and the hinge portion 25. 7) so that the support members 10, 20, 60 and the locking member 40 are circular, as shown in FIG. 7, and then the pipe blade 110 is placed in the cutting position. Adjust the position of.

이상태에서 도 9b에 도시된 바와 같이 잠금부재(40)를 회전시키면 끼움돌부(42)가 제 3,4 끼움홈(24)(62)을 따라 이동되며, 조임볼트(46)의 위치가 돌부(52)를 따라 이동하게 되는 것으로 상기 잠금부재(40)는 제 2 볼트(93)에 의해 회전될 수 있는 범위가 제한된다.In this state, as shown in FIG. 9B, when the locking member 40 is rotated, the fitting protrusion 42 is moved along the third and fourth fitting grooves 24 and 62, and the position of the tightening bolt 46 is changed to the protrusion ( By moving along the 52, the locking member 40 is limited in the range that can be rotated by the second bolt (93).

상기 조임볼트(46)를 돌부(52)에 조여주면 조임부재(50)가 파이프(110)의 외경을 물어주게 된다.When the tightening bolt 46 is tightened to the protrusion 52, the tightening member 50 asks the outer diameter of the pipe 110.

핸드 커터기(100)를 구동시키고 조절볼트(73)를 보여주게 되면 깊이 조절 부재(74)가 안내홈(72)을 따라 전방으로 이동함으로써 도 10에 도시된 바와 같이 브라케트(80)에 결합된 커터날(101)이 파이프(110)를 절단하게 된다. When the hand cutter 100 is driven and the adjusting bolt 73 is shown, the depth adjusting member 74 is moved forward along the guide groove 72 to be coupled to the bracket 80 as shown in FIG. 10. The cutter blade 101 cuts the pipe 110.

이 상태에서 커터기(100)를 이동시키면 회전부재(30)의 끼움돌부(31)가 제 1,2 끼움홈(12)(22)을 따라 안내됨으로써 도 11에 도시된 바와 같이 커터날(101)이 파이프(110) 주위를 공전하여 절단 작업이 이루어지게 된다. When the cutter 100 is moved in this state, the fitting protrusion 31 of the rotating member 30 is guided along the first and second fitting grooves 12 and 22, thereby cutting the cutter blade 101 as shown in FIG. 11. The cutting operation is performed by revolving around the pipe 110.

도 12는 파이프(110)가 조임부재(50)에 의해 고정된 상태에서 본 발명의 파이프(110)를 회전 시킴으로써 절단 작업이 이루어지도록 한 상태를 보인 도면으로써 이 경우 본 발명의 지지부재(10)(20)(60)와 회전부재(40)를 받쳐주는 반원형 축받이(121)를 갖는 받침대(120)를 사용할 수 있다.12 is a view showing a state in which the cutting operation is made by rotating the pipe 110 of the present invention in a state in which the pipe 110 is fixed by the fastening member 50. In this case, the support member 10 of the present invention. A pedestal 120 having a semicircular bearing 121 supporting the 20 and 60 and the rotating member 40 can be used.

이와같이 커터기(100) 또는 지지부재(10)(20)(60)를 회전시켜 절단 작업이 완료된후 파이프(110)를 좌우로 이동시키려고 할 경우에는 조임볼트(46)를 풀고 잠금부재(40)를 반대방향으로 회전시킴으로써 조임부재(50)가 제 2 볼트(93)를 중심으로 젖혀질 수 있도록 하면 되는 것으로 파이프(110)를 좌우로 이동시키는 것만으로 파이프(110)의 절단폭을 정밀하게 조절할 수 있다.In this way, when the cutter 100 or the supporting members 10, 20, 60 are rotated and the pipe 110 is to be moved left and right after the cutting operation is completed, the tightening bolt 46 is loosened and the locking member 40 is removed. The fastening member 50 can be flipped about the second bolt 93 by rotating in the opposite direction, and the cutting width of the pipe 110 can be precisely adjusted by only moving the pipe 110 from side to side. have.

도 13은 본 발명의 제 1 지지부재(10)에 2개의 커터기(100)를 설치한 실시예를 보인 도면으로써, 이것은 도시된 바와 같이 회전부재(30)를 링모양으로 형성하고 마주보는 위치에 2개의 결합부재(70)와 브라켓트(80)를 통해 커터기(100)를 각각 설치하여서 된 것이다.FIG. 13 is a view showing an embodiment in which two cutters 100 are installed in the first support member 10 of the present invention, which is formed in a ring shape and faces the rotating member 30 as shown.
