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.
