Abstract

PURPOSE:To form beads with a small number of small-size dies by making local beading on a sheet work with a punch comprising a groove-shaped recessed surface on which the groove widths on both ends are spread out like an unfolded fan and a die comprising a projection formed surface near the center. CONSTITUTION:The punch 53 in which a groove width is spread out like the unfolded fan near both ends of recessed formed surface 51 and the die 45 which has a projection formed surface 63 near the center of the recessed formed surface 51 do initial work of the starting point A for working a sheet work to obtain an upward protrusion of arcuate section. A punch 85 similar to the punch 85 similar to the punch 53 and having no curved surface part in the corner part of the groove section and a die 89 in which the upper end face of the die 65 is a nearly rectangular plane part 87 and which is round near the lower side corner send little by little the work from the initial working point A to form beads by lapping the work. Continuously, one side edge of the bead 45 at least is repeatedly cut by a cutting punch and a cutting die to obtain a product 47.
