Coiling forming control device and method for hot coiling box

The invention relates to a coiling forming control device for a hot coiling box. The control device comprises a deflection roller, a lower bending roller, a first upper bending roller, a second upper bending roller, an inclined guide plate, a laser detection line, an oil cylinder, a forming roller, an arc-shaped guide plate, a 1 # carrier roller, a 2 # carrier roller, a second carrier roller oil cylinder, a hydraulic motor and a hydraulic system, wherein the lower bending roller is fixedly arranged on a memorial archway; the 1 # upper bending roller and the 2 # upper bending roller are arranged on a pinch roller frame; the oil cylinder can enable the pinch roller frame to drive the two rollers to lift up and fall down around a fulcrum a; the 1 # upper bending roller and the 2 # upper bending roller respectively form a certain roller gap S with the lower bending roller; the inclined guide plate is installed between the lower bending roller and the forming roller and plays roles in transition, guiding and formi
