도 4는 본 발명에 따른 용융절단설 제거장치의 이동을 개략적으로 나타내는 도면이다.Figure 4 is a view schematically showing the movement of the melt cutting snow removal apparatus according to the present invention.

주편이 만곡부를 지나 절단지점에 도달하면 토치커터(16)에 설치된 클램프(18)를 주편의 표면에 하강시켜 클램프(18)와 주편을 밀착시키므로 토치커터(16)가 주편의 이동속도와 동일한 속도로 이동된다.When the cast piece reaches the cutting point after the bent portion, the clamp 18 installed on the torch cutter 16 is lowered on the surface of the cast piece to bring the clamp 18 and the cast piece into close contact with each other, so that the torch cutter 16 is at the same speed as the moving speed of the cast piece. Is moved to.

이 때 토치커터(16)에 설치된 타격부재(28)는 토치커터(16)와 동일한 속도로 이동하게 되며 카날(12)의 측벽(24)에 형성된 캠(30)에 위해서 후진하여 스프링(34)을 압축시킨다.At this time, the striking member 28 installed in the torch cutter 16 moves at the same speed as the torch cutter 16 and moves backward for the cam 30 formed on the side wall 24 of the canal 12. To compress.

타격부재(28)가 후진되다가 캠(30)의 선단을 지나는 순간 타격부재(28)의 자중과 스프링(34)의 탄성력에 의해서 해머(28b)가 카날(12)의 측벽(24)을 타격하게 된다.As soon as the striking member 28 is reversed and passes the tip of the cam 30, the hammer 28b strikes the side wall 24 of the canal 12 by the weight of the striking member 28 and the elastic force of the spring 34. do.

따라서 타격부재(28)에 의해 타격된 측벽(24)은 진동되어 측벽(24)에 부착된 용융절단설이 카날(12)의 바닥으로 낙하하게 된다.Therefore, the side wall 24 hit by the striking member 28 is vibrated so that the melt cutting snow attached to the side wall 24 falls to the bottom of the canal 12.

이와 같이 용융지금설을 제거하면서 동시에 토치노즐(20)을 사용하여 주편을 절단한다.In this manner, the molten metal is removed and the cast pieces are cut using the torch nozzle 20 at the same time.

주편이 절단되면 작동실린더(38)를 축소시켜 채널(26)을 회동시키므로 채널(26)과 채널(26)에 결합된 타격부재(28)를 캠(30)에 대응되지 않도록 한다.When the cast piece is cut, the working cylinder 38 is reduced to rotate the channel 26 so that the striking member 28 coupled to the channel 26 and the channel 26 does not correspond to the cam 30.

다음으로 토치커터(16)를 역전시켜 대기위치로 이동시킨다. Next, the torch cutter 16 is reversed and moved to the standby position.

이와 같은 본 발명에 따른 용융절단설 제거장치는 용융절단설이 측벽에 부착됨과 동시에 제거되므로 이 용융절단설을 제거하기 위해 작업자가 고열의 밀폐공간으로 들어갈 필요가 없다.The apparatus for removing melt cutting according to the present invention does not require the operator to enter a high-temperature sealed space to remove the melt cutting snow as the melt cutting snow is attached to the side wall and removed at the same time.

따라서 작업환경이 개선되고 고열로 인해 발생되는 안전사고를 방지할 수 있다. Therefore, the working environment can be improved and safety accidents caused by high heat can be prevented.                     

또한 용융절단설이 토치커터의 이동을 방해하는 경우가 발생되지 않으므로 연주가 끊기지 않게 되어 생산성이 향상된다.In addition, since the melt cutting does not interfere with the movement of the torch cutter, the performance is not interrupted and productivity is improved.
