【Abstract】 Due to the problems of precision and intelligence fabrication in plate forming, experiments of plate bending for 6～8 mm plates with advanced induced heating equipment were conducted. Thermal cycles were measured with K type thermal-couple and transient measurement system, and the influence of moving speed of induced heating coil on plate temperature was also examined. Based on theoretical analysis, different heating patterns were applied to generate bent plates with saddle and sail shapes; applying three coordinates locator, the out-of-plane bending distortions in longitudinal and transverse directions were measured. Plate forming with induced heating was demonstrated with experiment and measured results.更多还原
