Abstract
본 발명은 피절단재를 절단하는 가스절단기의 예열시간 제어장치에 관한 것으로, 이는 작업자가 미리 예열시간을 판넬 내부의 타이머에 설정하여 예열시간을 조정하는 방식으로 절단하고자 하는 피절단재의 두께에 따라서 이전의 실험에 의하여 적정 예열시간을 구한 후 절단할때마다 적정 예열시간을 타이머에 설정해야 하는 불편이 있고, 더우기 사용가스의 압력 및 유량이 변동되었을 시에는 적정 예열시간이 틀려지게 되므로 작업자가 항시 감시해야 하는 종래기술의 문제점을 해소하고자 하는 것이다.The present invention relates to a preheating time control device for a gas cutting machine for cutting a cutting material, which is set by the operator in advance by setting the preheating time to a timer inside the panel and adjusting the preheating time according to the thickness of the cutting material to be cut. It is inconvenient to set the proper preheating time in the timer every time after cutting the proper preheating time according to the previous experiment. Moreover, when the pressure and the flow rate of the used gas are changed, the proper preheating time is changed. It is to solve the problems of the prior art to be monitored.
이에 따른 본 발명은 절단팁과 피절단재 간에 전압을 인가하고, 이 피절단재에 화염을 가열하는 정도에 따라 피절단재의 온도상승에 비례한 전압변화를 검출하여 절단팁의 종류에 따라 입력설정된 기준치에 도달하면 예열완료 시점을 종료함과 동시 절단공정으로 자동실행하는 가스절단기의 예열시간 제어장치를 제공하므로서 별도의 센서 부착없이도 예열상태를 모니터링할 수 있고, 피절단재의 두께에 따라 예열완료 시간의 자동 결정으로 작업상에 편리함을 줄 수가 있는 동시 정확한 예열시간 제어에 의해 가스의 소비량을 줄일수 있는 효과를 제공한다.Accordingly, the present invention applies a voltage between the cutting tip and the cutting material, detects a voltage change proportional to the temperature rise of the cutting material according to the degree of heating the flame to the cutting material, and sets the input according to the type of the cutting tip. When the standard value is reached, the preheating time control is completed and the preheating time control device of the gas cutting machine which is automatically executed by the cutting process can be monitored, so that the preheating state can be monitored without attaching a sensor. The automatic determination of the gas provides the effect of reducing gas consumption through simultaneous precise preheating control, which can be convenient for operation.
