Workflow of the present invention is as follows:
(1) with the steel pipe work piece hoisting to material supporting rack, guarantee workpiece center symmetry on material supporting rack, off-centre is no more than 100mm, material supporting rack can be deposited 5 steel pipes simultaneously;
(2) external diameter, length parameter, the flange angle of inclination of input steel pipe on touch-screen;
(3) start the roller carriage, the roller carriage, is cut the fork opening angle and is adjusted to special angle automatically to certain height according to steel pipe parameter automatic lifting;
(4) adjust the two ends walking carriage, system regulates the two ends chuck spacing and the chuck anglec of rotation, and chuck distributes in bin center line bilateral symmetry, confirms that column is whether vertical or is offset;
(5) steel pipe flange is lifted on the electric chuck of flange assembly machine, start knob, clamping flange;
