Description
(54) СПОСОБ ПЕРИОДИЧЕСКОЙ ПРОКАТКИ ТРУБ(54) METHOD FOR PERIODIC PIPE ROLLING
кий прутом 5, KOTOpuii служит при деформации заготовки второй парой валков подвижной в осевом направлении опра1вкой. Таким образом , в зоне действи первой пары валков заготовка деформируетс на неподвижной конической оправке, а в зоне действи второй пары - на подвижной цилиндрической оправке. Из прокатанной таким образом трубы, с практически любым размером калиброван)гаго Внутреннего капала, извлекают цилиндрический пруток - оправку.The cue rod 5, KOTOpuii, serves to deform the workpiece with a second pair of rolls moving in the axial direction by the casting. Thus, in the zone of action of the first pair of rollers, the billet is deformed on a fixed conical mandrel, and in the zone of action of the second pair on a movable cylindrical mandrel. A cylindrical bar, a mandrel, is extracted from a pipe rolled in this way, with virtually any size calibrated by the inner inner drip.
Осуществление предлагаемого способа возможно па станах периодической холодной прокатки, оборудованных клетью с двум и более парами валков.The implementation of the proposed method is possible on periodic cold rolling mills equipped with a cage with two or more pairs of rolls.
Предложенный способ продольной периодической прокатки позвол ет получить толстостенные трубы малого диаметра -с калиброваиным внутренним каналом при высокой производительности процесса, с высоким качеством внутренней поверхности и повышенной точностью впутреппего диаметра.The proposed method of longitudinal periodic rolling allows to obtain thick-walled pipes of small diameter — with a calibrated internal channel with high process efficiency, with high quality of the inner surface and increased accuracy of the additional diameter.
