Abstract

The utility model relates to a novel horizontal four-shaft numerical control steel tube flame cutter which is characterized in that a main shaft rotates horizontally (a C shaft), a slide carriage moves along the direction which is parallel to a shaft line of the main shaft (a Z shaft), a slide plate moves upwards and downwards along the vertical direction which is vertical to the shaft line of the main shaft (a Y shaft), and a cutting torch swings in the vertical shaft sectional plane of the main shaft (a A shaft). When the A shaft, the C shaft, the Y shaft and the Z shaft are linked and are conducted with the numerical control, the cutting torch can trace the radial bouncing movement on the steel tube again, and can cut the intersecting line of a branch tube, the oblique end face curvature of the steel tube, the intersection line of a shelled shrimp knob of a welded elbow of the steel tube and the welding groove surface with variable pitch of the steel tube.
