METHOD OF MAKING MISSILE BODIES Russian patent published in 1997 - IPC

Abstract RU 2087217 C1

FIELD: plastic metal working. SUBSTANCE: method comprises steps of using waste body of missile as initial blank with diameter of its cylindrical portion consisting 1.1-1.6 of diameter of cylindrical portion of ready product; cutting off 20-40% of body length at side of variable diameter ogive; at side of blank bottom heating its sleeve-like different thickness portion whose length is equal to diameter of cylindrical portion, reducing end of said portion in cylinder-cone die by means of stepped punch for increasing bottom thickness by 2-3 times; rolling heated blank in piercing mill for helical rolling on mandrel, calibrating bottom portion in die and pushing it through unit of roller casings for receiving accurate-dimension smaller size missile body. EFFECT: increased accuracy of missile body.
