The invention can be defined in its most general form as a device for sheet material corrugation by means of bending and can be used in production of light core for sandwich panels, and elements of heat-exchange apparatus. The device includes the pivotedly connected in-between shaping and auxiliary systems of dies ( 4 ) and the drive for their transformation including the system of vacuumization and the chamber ( 3 ) made of flexible gas-proof material where the latter of said systems is fixed. Used to set the system of shaping dies ( 4 ) into its initial plane state is the mechanism made in the form of rigid chamber with the perforated cap ( 2 ) providing the possibility to connect the chamber to the system of vacuumization. The device also includes the subsidiary flexible removable vacuum chamber ( 8 ) wherein the blank ( 6 ) from sheet material is placed in contact with the shaping system of dies ( 4 ). Said chamber and the transformation drive chamber have a common wall rigidly connected to the shaping and auxiliary systems of dies ( 4 ) at locations of their pivot connection.
