The invention discloses an air pressure pipe bending machine. The machine comprises a worktable, a cylinder (5), a cylinder component, a pipe bending pressure tank (7) and rolling grooves (8), wherein a cylinder piston of the cylinder (5) is connected with the pipe bending pressure tank (7) through a telescopic shaft rod (6); the pipe bending pressure tank (7) is provided with a semi-circular notch of which the diameter is matched with that of a pipe; the worktable is provided with two rolling grooves (8) for positioning the two ends of the pipe and matching with the pipe bending pressure tank (7) to bend the pipe; each rolling groove (8) is provided with a semi-circular notch of which the diameter is matched with that of the pipe; and the cylinder piston moves forwards or backwards to push the telescopic shaft rod (6) and the pipe bending pressure tank (7) to move forwards or backwards along the direction of the worktable. The machine is high in pipe bending quality, ensures consistent and attractive bends,
