Resumo
Current geometric requirements on pipe—especially thin-walled pipe for gas pipelines—set strict limits on the deviation of the cross section in shaping. A special control algorithm for the drives in the sheetbending machine minimizes local geometric errors in the cross section during the roller shaping of largediameter pipe from strip. Analysis of the nonuniformity in deformation permits the formulation of a cyclic operating sequence for the drives. Experiments confirm its effectiveness. On the basis of this research, automatic control of the drives in the sheet-bending machine is possible.
