Abstract

PURPOSE:To uniformly deform a blank plate and to increase the forming height by executing in order the former stage working using the punch whose top face is circular arcuated shape and the latter stage working using the punch whose top face is flat. CONSTITUTION:In case of bulging a resin laminated aluminum foil, the former stage working is executed by using the punch of a circular arcuated top face, thereafter the latter stage working is executed by using the punch of a flat top face. Therefore, the blank sheet is deformed enough at the punch top face by the former stage working, the clearance part of the punch and die having received no deformation at the former stage forming receives a deformation at the latter stage working, the whole blank sheet is deformed uniformly and sufficiently and the forming height is increased.
