Abstract

The invention discloses a method for manufacturing pressing dies for the ship curved plate pressing forming process. The method comprises the steps of S1, determining the base plane of a bottom plateof the upper pressing die and the base plane of a bottom plate of the lower pressing die; S2, determining the installation positions of pressing die sidewalls and pressing die partition boards on thebottom of the upper pressing die and the bottom plate of the lower pressing die; S3, determining line-type data of the pressing die sidewalls and the pressing die partition boards in the height direction; and S4, completing manufacturing of the pressing dies for the ship curved plate pressing forming process step by step according to the steps S1, S2 and S3. Through the method, the pressing dies are manufactured accurately and reliably; the method is scientific, flexible, short in cycle, low in cost and convenient to operate.

Description

technical field [0001] The invention relates to a manufacturing process method, in particular to a method for manufacturing a die for the stamping forming process of a ship curved plate. Background technique [0002] Most of the hull surface is composed of complex non-developable spatial surfaces, and the hull surface widely exists in important parts such as bow and stern, engine room and so on. Due to the complex processing and difficult forming of the double curvature outer plate of the hull, the shortening of the ship production cycle and the improvement of quality are seriously restricted. [0003] Over the years, shipyards at home and abroad have processed double-curvature hull panels, usually using a combination of manually operated presses and water-fired plate bending processes. The method is to use a roller plate machine or a hydraulic press to bend the plate transversely, and then use the water-fire bending technology to heat the plate longitudinally to achieve lo...
