Abstract
As a result of the trend of consumer demand for many metallic shell products, the study of the rapid and flexible sheet metal forming has received considerable attention. In the present paper, a rapid and flexible draw-bend forming machine using a slitting die has been developed for the small-batch manufacture of shin strips with a curvilinear cross section. Because one-stage forming with a slitting die could not prevent the growth of the wrinkle and the warp of formed strip shell of shin metallic sheet, two-stage forming method was invented using two slitting dies and high quality strip goods with a curvilinear cross section were formed by controlling the position of the dies.
