Automatic ignition device of automatic gas cutting machine for cutting steel sheet

摘要

The present invention relates to an automatic ignition device for an automatic gas cutter for cutting a steel sheet, and to an automatic ignition device for an automatic gas cutter that can protect an electric wire at a high temperature from high heat and prevent the metal from being fused to an ignition tip. It is about.;The automatic ignition apparatus of the present invention is provided with an automatic ignition tip (8) for igniting the crater (11) of the automatic gas cutter for cutting the steel sheet (7), wherein the automatic ignition tip is fixedly supported. The frame 24, the frame plate 30 on which the frame is fixed, the motor 12 for moving the frame plate up and down, and the rotational force of the motor to the frame plate 30. One side is connected to the rotational shaft of the motor via worm and worm gear 18 and 18a for transmission and the other is connected to the frame plate via pinion and rack gear 20 and 20a. And a transmission shaft (14) and a cylinder (10) fixed to the frame plate so as to rotate the free end of the frame plate by 90 degrees.
