FIELD: metal forming.
SUBSTANCE: invention group relates to the field of metal forming and can be used in the manufacture of stamped products from hard-to-form metals and alloys, in particular titanium. A solid lubricant sheet is prepared by applying a colloidal lubricating suspension to the surface of the glass fabric with a surface density of the applied layer after drying of 20…80 g/m2. The opposite surface is coated with an enamel slip containing water, glass particles, bentonite and adhesive filler. A sheet of solid lubricant is placed between the surface of the heated workpiece and the engraving surface of the upper and lower halves of the die. The surface of the sheet with a layer of colloidal suspension faces the surface of the engraving of both halves of the stamp, and the surface with enamel slip faces the surface of the workpiece.
EFFECT: invention provides improved shaping of forgings in the die and increase the durability of the die tool.
