METHOD OF T-BRANCH TYPE DETAILS SHAPING OF, FOR INSTANCE, BODIES OF WATER- AND HEAT-COUNTERS MADE OF TUBULAR BILLET BY MEANS OF HYDRAULIC FORGING

摘要

FIELD: metallurgy. ^ SUBSTANCE: by means of hydraulic forging there is shaped lug for nose section in the form of truncated cone. It is removed section of part of truncated cone top less basis. Then it is implemented rolling-off -flanging by roll of the rest part of truncated cone top less basis. ^ EFFECT: improving of details, power inputs saving. ^ 7 cl, 3 dwg, 2 ex
