Abstract

Изобретение относитс  к металлургическому производству, а именно изготовлению металлических труб волочением с использованием самоустанавливающейс  оправки. Целью изобретени   вл етс  снижение обрывности труб из цветных металлов с отношением толщины стенки t к наружному диаметру, равным 0,03-0,06, и высотой зубьев (О,05-0,35)t. Деформацию осуществл ют обжатием по наружному диаметру, равным 15-18%, и по толщине стенки до 10%. Трубу-заготовку 1 подают к волоке 2 и самоустанавливающейс  оправке 3, имеющей элемент 4 с винтовыми канавками. Вращение элемента 4 оправки с винтовыми канавками и формирование зубчатого винтового л  на внутренней поверхности трубы осуществл етс  прот гиванием материала трубы через кольцевую щель между обжимным 5 и калибрующим 6 участками волоки и элементом 4 с винтовыми канавками . 3 ил. а (ЛThe invention relates to metallurgical production, namely the manufacture of metal pipes by drawing using a self-aligning mandrel. The aim of the invention is to reduce the breakage of non-ferrous metal pipes with a ratio of wall thickness t to outer diameter equal to 0.03-0.06, and the height of the teeth (0.05-0.35) t. The deformation is carried out by crimping on the outer diameter equal to 15-18%, and on the wall thickness up to 10%. The preform pipe 1 is fed to a die 2 and a self-aligning mandrel 3 having an element 4 with helical grooves. The rotation of the mandrel element 4 with screw grooves and the formation of a toothed screw l on the inner surface of the pipe is carried out by pulling the pipe material through the annular gap between crimp 5 and the calibrating 6 portions of the die and the element 4 with screw grooves. 3 il. a (L
