ПРОФИЛЕГИБОЧНЫЙ СТАН ДЛЯ ПРОИЗВОДСТВА ГОФРИРОВАННЫХ ПРОФИЛЕЙ

摘要

FIELD: plastic working of metals, possibly manufacture of corrugated sections. ^ SUBSTANCE: section bending mill includes upper and lower guides convergent along shaping direction and arranged in parallel relative to flanges of produced corrugated section; vertically closed traction chains with shaping bodies in the form of bodies of revolution. Shaping bodies are mounted on upper guides and they are non-driven ones in the form of row of rollers. Hinges of vertically closed traction chains are used as driven shaping members: said hinges are in the form of cylinder -rollers that may engage for forming corrugations with row of rollers of non-driven shaping members and may perform rolling motion along shaping direction on driving branches of said chains in lower guides. Said lower guides have friction paths. ^ EFFECT: simplified design of section sending mill. ^ 3 dwg
