Abstract

PURPOSE:To prevent the defective forming of a wrinkle, distortion, etc., by forming a flange on opposing two sides not held by a die and drawing it in the state of constraining this flange part. CONSTITUTION:The two sides a, a of a work W are held by a die 7 and blank holder 1. A sectional die 9 is abutted to the remaining two sides (b), (b) which are not held. A downward flange F is formed by bending it by ascending a punch 3. The punch 3 is further ascended with constraining the flange F by the sectional die 9 and punch 3 to perform drawing between the punch 3 and die 7. Consequently the blank flowing amt. to the center part of the work W is regulated and the forming part having no wrinkle nor distortion is obtd.
