Abstract

A forming method and equipment for a plate, comprising: making a single-curved plate; dividing processing zones on the plate to be buckled; trimming the processing zones to obtain the plate to be buckled; obtaining mold shape adjustment data, and adjusting the mold accordingly And bend the plate to be bent into a bent plate; detect the shape adjustment and correction data of the bent plate; bend the bent plate according to the shape adjustment correction data, and repeat the above steps for each processing partition until the plate to be bent Match the preset bending parameters. The invention solves the problems of low processing coverage, precision and efficiency in the prior art.

Description

technical field [0001] The invention relates to a manufacturing technology of a ship hull plate, in particular to a forming method and equipment for a plate. Background technique [0002] The line shape of the bow and stern area of ​​the ship is complex, and the curvature of the outer plate changes greatly. Due to the special area, such outer panels need to be divided into different shapes before processing. At present, for the processing of this kind of outer plate, major shipyards usually use the water-fire bending process, that is, to partially heat the steel plate in a linear or spot shape, so that the heated metal produces compression plastic deformation, and then uses water or air to cool it. When shrinkage plastic deformation is formed, and so on, the desired shape is obtained. This method is entirely based on experience, and the controllability in the molding process is poor. The water and fire bending process will damage the internal crystal structure of the stee...
