In this study, design and fabrication of a flexible forming machine are carried out for the purpose of manufacturing a prototype of curved plate block for hull structure used in shipbuilding industry. Flexible forming dies which consist of numbers of punches in an array form for upper and lower sides are designed in view of thick plate forming. A punch has formation of male and female screws to adjust its length with regard to a given surface, and all punches are supported by each other in punch housing. Software for process configuration and punch control are developed to operate the novel flexible forming machine. The software are composed of the punch height calculation part which uses an offset surface scheme. Prior to manufacturing of a prototype, numerical simulations for a saddle-typed thick plate forming process including metal forming and spring-back analyses are carried out to predict the forming performance. Experiments are also carried out to validate and confirm the feasibility of flexible forming technology in view of practical application of thick plate forming process. Curvature radii observed in the simulation and experiment are investigated and compared. Consequently, development and practical application of flexible forming technology to the thick plate forming process are described from design of the forming machine to manufacturing of the prototype. It is confirmed that the flexible forming technology suggested in this study has enough feasibility in new application of thick plate forming in shipbuilding structures which has been formed through expensive and laborious conventional line heating. 相似文献

The geometric basis for the design of a new process to form sheet metal into a flat, corrugated product is described. The underlying principle is to determine a surface between entry of the sheet into the device and the exit of the formed product such that all points across the width of the sheet under go as nearly as possible similar deformation histories and also that longitudinal strain in the sheet is minimized. The surface for forming a product having a sinusoidal profile and also that for a trapezoidal profile are presented as examples. For the sinusoidal product, an empirical equation is developed that relates the strain during forming with the initial and final width, the forming length and the number of profile segments.A physical model shows that a sheet can be formed to such a surface without straining or buckling. Although this paper does not describe the type of tooling or forming machine that would be used to plastically deform steel sheet, the authors believe such a device can be constructed. The results suggest that the new approach would reduce defects such as edge-wave, oil-canning and splitting and that the overall length of the forming device could be an order of magnitude smaller than that for existing roll-forming lines. 相似文献
