The invention relates to a method for pressing corrugated bulkhead by using a three-roller bending machine in hull construction process and a mold. The method comprises the following steps of: arranging and mechanically fixing lower pressing molds equivalent to the effective work length of lower rollers on two lower rollers of the three-roller bending machine by utilizing the prior configuration of the three-roller bending machine and the effective work length of the roller; arranging and mechanically fixing upper pressing molds equivalent to the effective work length of upper rollers on single upper roller of the three-roller bending machine; setting the length of a slot-shaped component according to the pressing lengths of the upper and the lower molds; loading board material; driving the upper mold by the upper roller of the three-roller bending machine, which is used as a lengthened oil pressure machine, to press-mold the corrugated component by one step through the mutual restriction of the upper and the lower molds. The inventive method can lengthen the process length of the corrugated component by only one three-roller bending machine which is equipped with the special mold, thereby reducing the number of the components. With reduced process and joint workloads, increased production efficiency and improved process precision, the shipbuilding cost is lowed.
