A large plate bending machine SKWB-2500 for shipbuilding with three-dimensional digital numerical control is developed, with which cold bending and forming 3D curved shell plate is performed automatically. Key technologies invented by Wuhan University of Technology and Shandong Surele Machinery Co., Ltd., are applied in this machine, including curved plate forming device with adjustable mold and square punch, online real-time detection in fast step by step approaching, etc. Wrinkles, indentation, spring back and other problems in ship plate cold bending have been solved successfully. Through series of tests it is shown that this machine can be seamlessly integrated with the plate production data generated by existing mainstream shipbuilding integrated manufacturing systems and achieve non-margin numerical control in forming 3D curved plate. The plate bended with this machine has a smooth surface and the bending efficiency is greatly improved. The performance of curved plate forming device and ship shell plate processing practice is set forth.
