본 발명은 평판 절단장치에 관한 것으로, 보다 상세하게는 절단하고자 하는 평판 상에서 토치가 CNC 제어 신호에 따라 전후, 좌우 방향으로 이동하면서 원하는 모양으로 평판을 절단할 수 있도록 한 평판 절단장치에 관한 것이다.The present invention relates to a flat plate cutting device, and more particularly, to a flat plate cutting device that allows the torch to cut the flat plate in a desired shape while moving the torch in the front and rear, left and right directions according to the CNC control signal.

일반적으로 평판(철판)을 절단하는 방법 중에 하나는 작업자가 토치를 들고 수작업으로 직접 절단하는 방법이 있다. 그러나 이와 같은 방법은 불편하고 작업 능률이 낮을 뿐만 아니라 정확한 절단 작업이 불가능하고 절단면이 매끄럽게 되지 않는 단점이 있다.In general, one of the methods of cutting a flat plate (iron plate) is a method in which a worker lifts a torch and cuts it by hand. However, such a method has disadvantages that it is not only inconvenient and low in work efficiency, but also impossible to cut accurately and the cutting surface is not smooth.

따라서, 최근에는 CNC를 이용한 절단방법이 개시되어 있다. 예를 들면, 대한민국 특허 등록 제610627호에는 자동 가스 절단기의 일례가 개시되어 있다. 이를 보면, 토치가 제2이송블럭을 따라 좌우방향(폭방향)으로 이송되고 제2이송블럭은 제1이송블럭을 따라 전후방향(길이방향)으로 이송되면서 금속판재를 절단하게 구성된다.Therefore, recently, a cutting method using a CNC has been disclosed. For example, Korean Patent Registration No. 610627 discloses an example of an automatic gas cutting machine. In this regard, the torch is transported in the horizontal direction (width direction) along the second transport block, and the second transport block is configured to cut the metal plate while being transported in the front-rear direction (length direction) along the first transport block.

그러나, 이와 같이 구성된 종래의 자동 가스 절단기는 토치가 전후로 이동될 때 그 이동 거리가 한정되는 단점이 있었다. 즉, 보통 평판을 보면 폭은 한정되어 있고 전후방향으로 긴 길이를 갖게되는 데, 종래의 자동 가스 절단기는 토치가 제1이송블럭을 따라 전후방향으로 이동하면서 절단 작업을 수행하다보니 제1이송블럭의 길이에 의해 그 이동 거리가 한정되는 단점이 있었다. 따라서 절단 위치가 제1이송블럭을 넘어가게 되면 절단기를 전체적으로 이동시킨 후 다시 작업을 수행해야 되는 불편함이 있었다.However, the conventional automatic gas cutting machine configured as described above has a disadvantage in that the moving distance is limited when the torch is moved back and forth. In other words, when looking at a flat plate, the width is limited and has a long length in the front-rear direction. In the conventional automatic gas cutting machine, the torch moves in the front-rear direction along the first transport block. There was a disadvantage in that the moving distance was limited by the length of. Therefore, when the cutting position exceeds the first transfer block, there is an inconvenience of having to perform the work again after moving the cutter as a whole.

본 발명은 상술한 바와 같이 제반되는 문제를 해결하기 위하여 안출한 것으로, 그 목적은 토치가 절단하고자 하는 평판의 폭만큼 좌우방향(폭방향)으로 이동되고, 평판의 길이에 따라서는 그 이동 거리가 한정되지 않고 평판의 전후방향(길이방향)을 따라 자유롭게 이동되면서 평판을 절단할 수 있도록 한 평판 절단장치를 제공하는데 있다.The present invention has been made to solve the problems described above, the object is to move the torch in the horizontal direction (width direction) by the width of the plate to be cut, the movement distance depending on the length of the plate The present invention is not limited thereto, and provides a flat plate cutting device capable of cutting a flat plate while freely moving along a front and rear direction (length direction) of the flat plate.

이와 같이 구성된 본 발명의 작동 및 작용 관계를 설명하면, 본 발명은 토치가 평판의 전후, 좌우방향을 따라 이동하면서 절단 작업을 수행하게 된다. 먼저, 평판(1)을 좌우방향(폭방향)으로 절단하고자 하는 경우에는 토치(40)를 지지하고 있는 이동판(44)이 좌우가이드바(30)를 따라 이동하면서 절단 작업을 실행하게 된다. 이때, CNC 몸체(20)의 위치에 따라 토치(40)가 좌우 이동되는 것에 더해, 좌우가이드바(30)가 좌우방향으로 이동하면서 위치를 선정하게 된다. 물론, 좌우가이드바(30)가 이동되는 원리는 랙기어(32)와 피니언기어(26)의 상호 작용관계에 의해 이동된다. 그리고 평판(1)을 전후방향(길이방향)으로 절단하고자 하는 경우에는 CNC 몸체(20)가 전후가이드판(10)의 가이드레일홈(12)을 따라 이동하면서 토치(40)를 이동시켜 절단 작업을 실행하게 된다. 즉, CNC 몸체(20) 내의 구동모터가 바퀴(22)를 구동시키게 되면, 바퀴(22)의 회전 방향에 따라 CNC 몸체(20)가 전후방향 으로 이동하면서 토치(40)를 이동시키게 된다. 또한, 본 발명은 이동판(44)의 각도표시눈금(44a)을 보면서 토치지지체(42)를 원하는 각도로 회전시키면 토치(40)의 각도가 조절된 상태에서 비스듬한 각도로 평판(1)을 절단할 수 있게 된다.Referring to the operation and action relationship of the present invention configured as described above, the present invention performs the cutting operation while the torch moves along the front, rear, left and right directions of the plate. First, when the flat plate 1 is to be cut in the left and right direction (width direction), the moving plate 44 supporting the torch 40 moves along the left and right guide bar 30 to perform the cutting operation. At this time, in addition to the torch 40 is moved left and right according to the position of the CNC body 20, the left and right guide bar 30 is selected while moving in the left and right directions. Of course, the principle that the left and right guide bar 30 is moved by the interaction relationship between the rack gear 32 and the pinion gear 26. When the plate 1 is to be cut in the front-rear direction (length direction), the CNC body 20 moves along the guide rail groove 12 of the front-rear guide plate 10 while moving the torch 40 to cut the work. Will run That is, when the driving motor in the CNC body 20 drives the wheel 22, the torch 40 moves while the CNC body 20 moves forward and backward in accordance with the rotation direction of the wheel 22. In addition, according to the present invention, when the torch support 42 is rotated at a desired angle while watching the angle display scale 44a of the moving plate 44, the flat plate 1 is cut at an oblique angle in a state where the angle of the torch 40 is adjusted. You can do it.

이상에서와 같이, 본 발명은 평판의 길이방향을 따라 CNC 몸체가 바퀴에 의해 전후이동을 하기 때문에 토치가 절단하고자 하는 평판의 길이방향을 따라 그 이동 거리가 한정되지 않고 자유롭게 이동시킬 수 있는 효과가 있다. 또한, 본 발명은 CNC 몸체를 기준으로 좌우가이드바가 랙기어와 피니언기어를 통해 좌측 또는 우측으로 선택적 이동이 가능하기 때문에 하나의 평판 상에서 좌우를 서로 다른 모양으로 절단하는 작업이 가능한 효과가 있다. 또한, 본 발명은 토치의 각도를 필요에 따라 원하는 각도로 경사지게 조절할 수 있기 때문에 평판을 비스듬하게 절단하는 작업이 가능한 효과가 있다.As described above, the present invention has the effect that the movement distance is not limited to the longitudinal direction of the plate to be cut because the CNC body is moved back and forth by the wheel along the longitudinal direction of the plate is free have. In addition, since the left and right guide bar can be selectively moved to the left or the right through the rack gear and the pinion gear based on the CNC body, the present invention has the effect of cutting the left and right in different shapes on one flat plate. In addition, the present invention can be adjusted to be inclined at the desired angle to the angle of the torch as needed, there is an effect that can be cut at an oblique plate.

이상에서와 같이 본 발명은 특정의 실시예와 관련하여 도시 및 설명하였지만, 청구범위에 의해 나타난 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 당 업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described in connection with specific embodiments as described above, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who owns it can easily find out.
