Description

Отходы трубопрокатного и трубосварочного производства в виде коротких обрезков труб используютс  обычно как металлический лом. Между тем они могут быть раскатаны до любого диаметра и толщины стенок и после этого использованы в виде более тонкостенных труб любого большего диаметра.Waste pipe-rolling and pipe-welding production in the form of short scraps of pipes are usually used as scrap metal. Meanwhile, they can be rolled out to any diameter and wall thickness and then used in the form of thinner pipes of any larger diameter.

Предлагаемый стан дл  поперечной раскатки коротких труб состоит из трех параллельных цилиндрических валков 1, 2 к 3 (см. чертеж), оси которых расположены в вершинах равностороннего треугольника. Все три валка получают вращение в одном направлении. Валки } и 2- приводные, а валок 3-нажимной и может переставл тьс  в вертикальном направлении при помощи гидравлических цилиндров 4.The proposed mill for transverse rolling of short tubes consists of three parallel cylindrical rolls 1, 2 and 3 (see drawing), the axes of which are located at the vertices of an equilateral triangle. All three rolls receive rotation in one direction. The rolls} and 2 are driven, and the roll is 3-pressure and can be rearranged in the vertical direction by means of hydraulic cylinders 4.

На передней (входной) станине стана размещена камера 5, снабжен-, на  окном 6, в которое закладываетс  заготовка 7. Перед поступлением на стан заготовка нагреваетс ,A chamber 5 is placed on the front (inlet) bed of the mill; it is equipped with a window 6 into which the workpiece 7 is laid. Before entering the mill, the workpiece is heated,

в нее закладываетс  оправка 5, вместе с которой при подн том валке 3. заготовка подаетс  в промежуток между валками / и 2, прижимаетс  валком 3 и подвергаетс  раскатке до желаемых размеров по диаметру и толщине стенки. В процессе раскатки заготовка прогреваетс  газовыми горелками 9.A mandrel 5 is inserted into it, together with which, with a raised roll 3. The blank is fed into the gap between the rolls I and 2, pressed by the roll 3 and subjected to rolling to the desired dimensions in diameter and wall thickness. In the process of rolling the billet is heated by gas burners 9.
