FIELD: metal processing.
SUBSTANCE: invention relates to the processing of metals by pressure and can be used in the manufacture of structural elements from ultra-high strength steel (UHSS) with an aluminum-silicon coating. A multi-stage device is used, comprising a lower part, a movable upper part, a pressing device made with the possibility of drawing the workpiece, and a device for cooling the workpiece. The billet is heated to a temperature above the billet austenitizing temperature and below the evaporation temperature of the billet coating. The fully heated billet is cooled in a cooling device, transported to a pressing device and thermoformed by drawing.
EFFECT: obtaining of products that do not require additional shot blasting and are well weldable.
