Automatic integral forming method for double-curvature plate of ship

An automatic integral forming method for a double-curvature plate of a ship, comprising steps of:

• a) constructing a loading system for integral forming, wherein said loading system for integral forming comprises a frame (10) and a control device disposed on said frame (10), a heat loading component (1), a pressure loading device, and a water spraying component (2) sequentially disposed on said frame (10), wherein said heat loading component (1) heats a plate (9) to be formed by line heating, and said pressure loading device comprises an upper pressure loading device (3) and a lower pressure loading device (4) collaborating with each other, thereby applying pressure on said plate (9);
• b) establishing a relationship between basic forming data and processing data of said plate (9) according to a requirement for a forming process, wherein said basic data comprises material properties, a thickness, a target shape, and a target curvature of said plate (9), and said processing data comprises shapes of an upper roller (36) and a lower roller (46), force applied thereby or displacement thereof, thereby enabling/disabling of said heat loading component (1) heating said plate (9) by line heating and a position thereof, input voltage and current for heat control, enabling/disabling of said water spraying component (2), water flow and a position thereof, and starting and ending positions, travel trajectories, and travel speeds of said heat loading component (1), said pressure loading device, and said water spraying component (2) that maintain loading status altogether or independently;
• c) making a prototyping software according to said relationship between said basic data and said processing data, installing said prototyping software on said control device, starting said prototyping software for said plate (9), inputting basic data into said prototyping software, thereby obtaining processing data according to said basic data, driving said heat loading component (1), said pressure loading device, and said water spraying component (2) to load said plate (9) so that said plate (9) is plastically deformed in double curvatures;
• d) monitoring a deformation effect of said plate (9) that is plastically deformed, detecting and feeding back if there is difference between a shape and curvature thereof and said target shape and curvature, restarting said prototyping software, thereby enabling said loading system to load said plate (9) until a double-curvature plate meeting requirement for a processing target is formed if there is difference therebetween.
