Abstract

FIELD: metal pressure forming. SUBSTANCE: punch for shaping by stretching includes a casing of changeable templates and an envelope in the form of three-layer elastic construction, consisting of outer sheet facings and a corrugated sheet filler between them, rigidly connected with the facings. The envelope is jointly connected with an apex of the templates. Upon stretching the blank adjoins to a surface of the elastic envelope and also obtains a curvature, being set by the changeable templates. EFFECT: enhanced efficiency of manufacturing process with use of such punch. 1 cl, 2 dwg
