AUTOMATIC LINE OF HOT STAMPING Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: automatic line has a mechanism for bar cleaning and washing, induction heater for preliminary bar heating, device to apply working grease on the bar, induction heater for bar heating up to the temperature of plastic deformation. All members of the line on the way of manufacturing process are tied by transportation means. Then using equipment for formation of singled blanks made from the bar, presented by a cross-screw rolling mill, the bar cutting into sphere-shaped blanks with flash. Then the grips of the transporting mechanism transfer the blanks to a mechanism for processing of unfinished blanks and flash cutting. Then the blanks are heated for stamping by a stamping press. The line may have additional induction heater for singled blanks and a stamping press. In the last version transportation and distribution of sphere-shaped blanks to stamping positions is exercised by the mechanism of singled transfer of blanks and its grips. EFFECT: automatic production of blanks of glass-shaped pieces by hot volume stamping. # cl, 11 dwg
