Abstract

PURPOSE: To prevent the generation of strain on the bead forming products by operating punching force of the punching machine instantaneously to the work, extruding a minute amount of the bead continuously and forming the required bead.
CONSTITUTION: In the state setting the work 1 between an upper die 2 and a lower die 4, this lower die 4 is moved up and down while being guided with the punch against the elastic force of an elastic body 5 by the momentary and impacting punching force of the vertical reciprocating motion (high speed and a short cycle) of the upper die 2. The punching part 3 is made in and out from the upper surface 4a of the lower die 4, and continuously knocks out the work 1 to the space of the through groove 2b, and the bead B of the prescribed shape is formed by accumulating this minute working amount.
