Abstract

The present invention relates to a die for cold-processing a sheet (1) made of high-tensile strength material, preferably high-tensile strength steel, said die comprising: - a die block (10) secured to a lower portion of said die; - a sheet press (20) which can be movably connected to an upper portion of said die; - a punch (30) for processing, in particular shearing and/or punching, the sheet (1); - heating means (40) adapted to tempering the material of the sheet (1). The invention is characterized in that said heating means (40) are associated with means (50,51,52) for collecting a scrap (2) obtained after the sheet (1) has been processed by the punch (30). A method for cold-working a sheet made of high-tensile strength material is also disclosed.
