Description
таких участков обеспечиваетс при прессовании через матрицу. Совмещение операций поперечно-винтовой прокатки и прессовани позвол ет приблизить вид напр женного состо ни пластической зоны к трехосному сжатию, что обеспечивает расширение технологических возможностей нроцесса и изготойление таких изделий как трубы с внутренним оребрением, профили с замкнутыми полост ми и с переменными по длине издели поперечными сечени ми.such sections are provided by pressing through a die. Combining the helical rolling and extrusion operations makes it possible to bring the appearance of the stress state of the plastic zone to a triaxial compression, which expands the technological capabilities of the process and makes products such as tubes with internal fins, profiles with closed cavities and transverse sections.

заготовок, отличающийс тем, что, с целью расширени технологических возможностей процесса путем приближени напр женного состо ни пластической зоны к трехосному сжатию, после прокатки заготовку прессуют через матрицу, которую вращают относительно прок атных валков, при этом ось вращени матрицы совмещают с осью прокатки.blanks, characterized in that, in order to expand the technological capabilities of the process by bringing the stress state of the plastic zone to a triaxial compression, after rolling the workpiece is pressed through a matrix that is rotated relative to the rolls, the axis of rotation of the matrix is aligned with the axis of rolling.
