Abstract

PURPOSE: To form fins easily and accurately by placing a ring-shaped blank on a base plate on which a cylinderical outer die, foamed urethane, and an urethane die are placed after internally fitted in this order, and screw-down forming this by means of a blank holder and a punch.
CONSTITUTION: A cylinderical outer die 11, foamed urethane 13 and a urethane rubber die 14 in this order and internally fitted and are disposed on a base plate 10, and a blank 24 is placed on the urethane rubber die 14. Thereupon, a blank holder 18 is lowered by operating a cylinder 21 to compress the urethane 13 and the die 14 in a vertical direction, then the space 15 of the die 14 deforms to a small diameter. Thence, when only the punch 23 is lowered, the blank 24 is reduced from the central part into the space 15 by the descending of the lower small-diameter part 23A. The reducing is accomplished until the upper large-diameter part 23B abuts on the blank holder 18, whereby a reduced part 26 is formed; at the same time, its bottom end is opposed to a curved guide surface 17a from above. Upon ending of the forming, the blank holder 18 and the punch 23 are moved upward and a movable cylinder 17 is moved upward, thence the formed product is taken out.
