종래에는 금속판재를 곡선을 따라 절단하고자 하는 경우, 쥐꼬리톱이나 절단가위를 사용하여 절단하였으나 작업이 힘들고 작업성이 낮은 단점이 있었다.Conventionally, when the metal plate is to be cut along a curve, it is cut using a rat tail saw or cutting scissors, but has a disadvantage in that work is difficult and workability is low.

또한, 비교적 발전한 방법으로 절단용 용접기나 산소용접기 또는 레이저 등에 의해 절단하였으나 작업과정이 용이하지 않았으며, 절단장비가 복잡하고 크기 때문에 작업장소에 따라서는 작업의 제한이 따랐으며, 장비가 고가인 단점이 있었다.In addition, the cutting process by cutting welding machine, oxygen welding machine or laser was relatively easy, but the working process was not easy. Due to the complexity and size of cutting equipment, the work was limited depending on the working place, and the equipment was expensive. There was this.

본 고안은 상기와 같은 종래 문제점을 해결하기 위해, 통상의 휴대용 전동공구에 연결시켜 어느곳에서나 쉽게 곡선 절단이 가능하도록 하고, 구조가 간단하여 휴대가 용이하고 제작비용이 저렴하도록 하는 금속판 절단기를 제공하는데 그 목적이 있다.The present invention, in order to solve the conventional problems as described above, by connecting to a common portable power tool to be easily cut curve anywhere, and provides a metal plate cutter that is simple in structure and easy to carry and low production cost Its purpose is to.
