PROGRESSIVE DEEP-DRAWING MACHINE

摘要

Index-feed deep drawing apparatus comprising a feeding device for intermittently indexing a long-sized work piece, wound in a hoop, in the longitudinal direction, and a plurality of punch/die sets disposed in the feeding direction of the work piece and adapted to sequentially carry out deep drawing at least on the work piece, in which an annealing device adapted to allow the work piece to pass is provided between the deep drawing punch/die sets so as to subject the work piece to intermediate annealing treatment.
