Su, S.; Hu, Y., and Wang, C., 2015. The key technology research about 3DCNC bending machine and experimental verification.

Due to the complex curved surface shape, large size and small batch about hull plate, the 3D CNC bending machine is emerged. It is a breakthrough in the ship 3D surface cold forming area and has great practical significance. The key and innovative technologies are as follows. They are the square head adjustable die forming device which can well solve the indentation and wrinkling problems in the forming process, the online real-time detection fast approximation gradually bending method which can quickly solve the spring back problem of hull plate forming and make sure the accuracy and the software and hardware integration control system which can realize the digital technology and automation of the CNC bending machine. The 3D CNC bending machine can solve the high-cost problem of overall die and the wrinkling and the indentation problem of the multi point forming technology, whose effectiveness and reliability can be verified through the sail plate and the saddle plate cold bending forming experiment.
