METHOD OF ROLLING HEXAGONAL PROFILES

摘要

FIELD: process engineering. ^ SUBSTANCE: proposed method comprises rolling of pre-finish hexagonal oval, its turning around through 90 and rolling in finishing hexagonal gage. Double rolling of every face of the profile and reduction of contact strains in rolling are provided for by using additional three gages to roll hexagonal profile, said gages being identical to finishing gage. First of said gages forms hexagonal profile, remaining three are used to gage said profile on turning around the strip relative to previous gage clockwise through 60 or counter clockwise through 60. Gaging in the last three gages is performed without changing the strip shape. ^ EFFECT: higher precision, longer life of rolls. ^ 3 cl, 5 dwg, 1 tbl
