Numerical control flame plasma cutting machine

The utility model belongs to the technical field of plasma cutting machines, particularly relates to a numerical control flame plasma cutting machine, and provides the following scheme aiming at the problems that most of the existing plasma cutting machines are fixed in height and inconvenient to adjust, so that higher workpieces cannot be processed when the higher workpieces appear. The device comprises a cutting machine, the bottom of the cutting machine is slidably connected with symmetrically-arranged shells, the inner wall of the cutting machine is slidably connected with a bottom frame, the top of a sliding rod is slidably connected with a sliding rod, the bottom of the sliding rod is rotatably connected with symmetrically-arranged pushing rods, and the number of the pushing rods and the number of the pushing rods are both two. According to the cutting machine, the electric push rod and the motor are started, the electric push rod unlocks the height of the cutting machine firstly, then the motor is star
