发明名称 DEVICE AND METHOD FOR DRAWING WITH HEATING
摘要 FIELD: process engineering.SUBSTANCE: set of inventions relates to metal forming, particularly, to forming articles by hot drawing. Electrically insulated blank is arranged in jacket nearby female die working surface to lock its opposite ends. Then, said blank is subjected to resistor heating and forming. Note here that radiant heat is fed to one or more blank sections and cooling is performed in female die.EFFECT: higher ductility.17 cl, 11 dwg
