FIELD: process engineering.
SUBSTANCE: invention relates to drawing of axially symmetric parts from sheet blanks. Semis are drawn at dies in job-by-job manner, first, at bottom mating that of axially symmetric part to extreme depth and with conical wall. Further jobs include configuring to the shape of axially symmetric part. At final job of drawing, semi-finished product results with wall, shape and sizes corresponding to those of box part with trimming allowances.
EFFECT: higher accuracy of sizes.
