Horizontal three-axle numerically-controlled steel-pipe flame-cutting machine

The utility model discloses a horizontal steel-pipe flame-cutting machine with the three-axle numerical control, which comprises a main drive device, an axial moving device, a lifting device and a cutting device of a mechanical part, a body and a numerical control part. The utility model is characterized in that a servo motor in the main drive device drives a main axle and a clamping chuck to rotate in a C axial direction, the axial moving device is parallel to move with the axial line direction of the main axle, and a lifting motor of the lifting device drives a lifting sleeve to act the upper and lower movement on a vertical column. The cutting device is arranged horizontally on the lifting sleeve, wherein, a cutting torch acts the swing in the sectional plane of a vertical axle of the main axle by winding a given swing center on an axial lead. Various cutting functions can be realized fully.
