step seven: after the to-be-corrected core rod (7) completely penetrates through the to-be-machined oil cylinder pipe (6), the electric telescopic rod (804) drives the oil cylinder pipe limit stop (805) to move downwards, so that two ends of the to-be-machined oil cylinder pipe (6) are not limited any more, a plurality of driving motors (5044) are started at the same time, and the to-be-machined oil cylinder pipe (6) after being corrected is pushed to the rolling supporting structure (9) through a plurality of groups of driving correction roller shafts (5042), so that the to-be-machined oil cylinder pipe (6) is supported on a plurality of supporting roller shafts (904) in a rolling mode.
