Abstract

PURPOSE: To obtain the non-defective product free from thickness reduction in the central part by applying compressive force to the outside circumferential part positioned between each punch of the blank while simultaneously pushing in the plural punches at the time of forming parallel deep-drawn parts.
CONSTITUTION: Punches 15A, 15B are suspendedly provided in correspondence to chambers 12A, 12B to the press side elevating body 14 on the stationary die 10 in which the pressure chambers 12A, 12B are formed in the state of having a partition wall 11. The blank 17 is held by a holder 16 on the die 10 and the punches 15A, B are pushed in, whereby deep drawing is accomplished. Here, the pressure plates 18A, 18B thinner than the blank 17 are so guided by guide members 19A, 19B as to make contact with the outside circumferential portions between the both punches 15A, 15B of the blank 17 and are disposed with their both end parts being fitted to the pressure plate holders 21A, 21B. Along with the pushing-in of the punches 15A, 15B, the compressive force by the pushing-in holders 21A, 21B is applied to the outside circumferential parts 17a, 17b of the blank 7, whereby the thickness decrease between the molded parts is prevented.
