Abstract

The invention discloses a technology for processing a large linear outer plate of a hull bulb bow. The technology comprises the steps of S1, performing overall preliminary deformation on the outer plate to be processed; S2, correspondingly fixing the preliminarily-deformed outer plate on a die and performing heat treatment on the outer plate; S3, using external force to press the heated outer plate till the outer plate is identical to the die in shape. An outer plate die mode and the heat treatment are adopted, the requirements for work skills are decreased, the deformation amount of the outer plate is easily controlled, the production efficiency is improved, the accuracy of the manufactured outer plate can be ensured, detection by means of a woody box is not needed, and working procedures are omitted. The hardness of the plate can be reduced through outer plate heating, deformation treatment performed by using the external force is facilitated, and the deformation speed is improved. By using a device for processing the large linear outer plate of the hull bulb bow, the technological steps can be quickly finished, a jacking device can be quickly moved through a closed frame, and the processing efficiency can be improved.

Description

technical field [0001] The invention relates to the field of processing the large linear outer plate of the bulbous nose of a hull, in particular to a processing technology and a processing device for the large linear outer plate of the bulbous nose of a hull. Background technique [0002] The principle of water and fire bending is that when the metal plate is heated to a certain temperature, due to the localization of the thermal field, the expansion of the heated metal is limited by the cooler metal, resulting in compression plastic deformation of the heated metal, and shrinkage when the metal plate cools. Under normal circumstances, this kind of shrinkage deformation exists in the entire thickness direction of the metal sheet, but due to the higher temperature of the heating surface, the amount of compressive plastic deformation is greater than that of the back side, and the shrinkage deformation formed is also larger than that of the back side, thus forming angular variat...
