Abstract

PURPOSE: To make sufficient the small number of times of press work, by forming the working plane of upper and lower forming dies so as to form a portion of the surface ofthe polyhedron touchin ginternally to the sphere, into the eggplant form, and by bending the steel plate wiht a large bending angle at the edge portion of the forming plane, and alsonby causing a permanent deformation at the crooked portion.
