Abstract
FIELD: metal working; particular, bending of honeycomb panels, including extra thin-walled ones. SUBSTANCE: sandwich panel is installed on supporting punch, and exterior facing is rolled over by sectors of pressing punch. The sectors come in contact with facing through heating band. In course of sectors rolling, panel is bent under conditions of uniformly distributed load and heating in places of force application. In so doing, bending of lower lining in zones of force application takes place in cold state (in region of elastic deformation) with subsequent thermal fixation of bent zones as the panel is heated. EFFECT: higher efficiency. 2 cl, 3 dwg
