Abstract

1. Способ изготовления пружин из стали с анизотропно ориентированной наноструктурой, включающий скоростной нагрев прутка до температуры выше точки Acфазовых превращений, пластическую деформацию прутка винтовым обжатием с закручиванием в направлении сжатия витка пружины, навивку пружины, закалку и отпуск, отличающийся тем, что осуществляют горячую навивку пружины после пластической деформации при температуре выше Acс немедленной повитковой закалкой.2. Способ по п.1, отличающийся тем, что скоростной нагрев заготовки осуществляют до температуры не менее чем на 50°С выше точки Ac.1. A method of manufacturing springs made of steel with an anisotropically oriented nanostructure, including high-speed heating of the bar to a temperature above the point of Ac phase transformations, plastic deformation of the bar by screw compression with twisting in the direction of compression of the coil of the spring, winding the spring, hardening and tempering, characterized in that it is hot-wound springs after plastic deformation at temperatures above Ac with immediate hardening. 2. The method according to claim 1, characterized in that the high-speed heating of the preform is carried out to a temperature of at least 50 ° C above the point Ac.
