금속판 절단용 커터{Cutter for metal plate}Cutter for metal plate

본 발명은 금속판 절단용 커터에 관한 것으로서, 특히 금속판 소재의 절단 속도를 향상시키고 절단면이 깨끗하며 절단비트(bit)의 교체 작업이 용이한 금속판 절단용 원형 커터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter for cutting a sheet of metal, and more particularly, to a circular cutter for cutting a sheet of metal, which improves cutting speed of a sheet metal material, cleans the cutting surface, and facilitates replacement of cutting bits.

일반적으로 금속판의 절단 작업은 토오치 절단기 혹은 절단 톱기계를 사용하여 이루어진다.Generally, the cutting of a metal plate is performed using a torch cutter or a cutting saw machine.

예를 들어 대한민국 공개 특허공보 제 1999-73381호(1999. 10. 5)에는 절단 토오치를 이용하여 철판을 절단함에 있어서, 상기 절단 토오치의 전방에 예열용 히팅 토오치를 절단 토오치의 본체에 연결관을 매개로 동시 점화되도록 설치하고, 메인 유니트의 커버 하단에 로울러가 부착된 솔레노이드 밸드 전원 차단용 리미트 스위치를 핀을 축으로 회동 가능하게 탄력 설치하여, 절단 작업 시간이 빠르고 자동 절단이 가능하도록 한 절단기가 개시되어 있다.For example, Korean Laid-Open Patent Publication No. 1999-73381 (October 5, 1999), in cutting a steel plate using a cutting torch, the main body of the cutting torch for preheating heating torch in front of the cutting torch. It is installed so as to ignite at the same time through the connecting pipe, and the solenoid valve power cut-off limit switch equipped with a roller at the bottom of the cover of the main unit is resiliently installed by rotating the pins so that cutting time is quick and automatic cutting is possible. A cutter is disclosed.

또한 대한민국 실용신안공보 제 1989-3711호(1989. 6. 2)에는 절단 쇠톱을 권취한 상,하 휠의 원륜 둘레 표면을 중심부가 점차 높여진 고무 피막층을 접착하여 높여진 중심부에 절단톱의 면부가 접설되도록 하므로, 톱날의 마모를 방지하여 사용 수명을 연장할 수 있도록 한 만능절단 톱기계가 개시되어 있다.In addition, Korean Utility Model Publication No. 1989-3711 (Jun. 2, 1989) adhered to the surface of the upper and lower wheels of the upper and lower wheels wound with a cutting hacksaw, to which a rubber film layer was gradually raised to the center. Since the parts are folded, a universal cutting saw machine is disclosed, which prevents abrasion of the saw blade and extends its service life.

그러나 상술한 종래의 금속판 절단장치들은 금속판의 절단 작업 속도가 느리고, 절단된 금속판의 절단면이 불규칙하게 형성되는 문제점이 있다.However, the above-described conventional metal sheet cutting apparatus has a problem in that the cutting speed of the metal sheet is slow and the cut surface of the cut metal sheet is irregularly formed.

보다 구체적으로 전자의 토오치를 이용한 자동 절단기는 토오치에서 발생되는 불꽃을 이용하여 금속판을 가열 절단하게 되는바, 이 경우에는 작업 속도가 느릴뿐아니라 절단면이 열에 의해 용융되면서 울퉁불퉁하게 되어 그 표면 품질이 떨어지는 문제점이 발생하게 된다.More specifically, the automatic cutting machine using the electronic torch heat-cuts the metal plate using the spark generated from the torch. In this case, the cutting speed is not only slow but also the cutting surface is melted by heat, resulting in surface quality. This falling problem occurs.

또한 후자의 만능절단 톱기계은 고탄소강이나 합금강으로 형성되고 날부가 열처리된 띠톱을 이용하여 금속판을 절단하게 되는바, 이 경우에는 절단면의 품질이 양호하기는 하지만 금속판의 절단 속도가 특히 떨어지는 문제점이 발생하게 된다.In addition, the latter universal cutting saw machine is made of high carbon steel or alloy steel, and the metal plate is cut using a band saw heat treated with a blade bar. In this case, although the quality of the cutting surface is good, the cutting speed of the metal plate is particularly low. Done.

한편 톱기계의 경우에는 원판 가장자리에 분할형 톱날을 몇개씩 부착하여 사용하는 경우도 있다. 이러한 원판 톱기계는 띠톱의 경우와 마찬가지의 문제점이 있으며, 아울러 톱기계의 경우에는 톱날의 수명이 짧고 잦은 손상이 발생되며, 일부 톱날의 손상시 전체 톱을 교체해야만 하는 문제점이 있다.On the other hand, in the case of a saw machine, several saw blades are attached to the edge of the disc. This disc saw machine has the same problems as in the case of a band saw, and in the case of the saw machine, the life of the saw blade is short and frequent damages occur, and when the saw blade is damaged, the entire saw must be replaced.

이러한 종래 기술의 문제점을 해결하기 위한 것으로서, 본 발명은 원형 커터 구조를 채용하되 그 둘레에 다수개의 절단비트를 착탈식으로 결합하여 용이하게 교체할 수 있도록 하며, 아울러 금속판 소재의 절단 속도를 향상시키고 절단된 소재의 표면 품질을 향상시킬 수 있도록 한 금속판 절단용 커터를 제공함에 그 목적을 두고 있다.In order to solve the problems of the prior art, the present invention adopts a circular cutter structure, but a plurality of cutting bits are detachably coupled around the removable to facilitate replacement, and also improve the cutting speed of the metal plate material and cut It is an object of the present invention to provide a cutter for cutting a sheet of metal that can improve the surface quality of a finished material.
