Description
Известны способы холодной прокатки тонкостенных и особотонкостенных труб на конической оправке пилигримовыми валками, калибр которых выполнен открытшл .Known methods of cold rolling of thin-walled and very thin-walled tubes on a conical mandrel are pilgrim rolls, the caliber of which is made open.
Дл улучшени качества прокатываеMtax труб и увеличени производительноти тонкостенных и особотонкостенных труб калибр в.алков, в котором осуществл етс деформаци заготовки, выполн ют закрытьм.In order to improve the quality of rolled Mg pipes and increase the productivity of thin-walled and particularly thin-walled pipes, the caliber of rolls, in which the workpiece is deformed, is closed.
На чертеже схематически представлена часть двухвалкового стана холодной прокатки дл осуществлени способа .The drawing shows schematically a part of a two-roll cold rolling mill for carrying out the method.
Холодную прокатку тонкостенной или особотонкостенной трубы 1 производ т на конической оправке 2 валками 3, опирак цимис на опорные плиты 4 и имегацими малый диаметр и переменный профиль ручь по всей длине бочки. От осевого смещени валки фиксируютс при помс ди бурта (на одном из них) и образуют замкнутый калибр.Cold rolling of a thin-walled or very thin-walled pipe 1 is carried out on a conical mandrel with 2 rolls 3, leaning on the base plates 4 and pulling a small diameter and a variable stream profile along the entire length of the barrel. From the axial displacement, the rolls are fixed at the bottom of the drill (on one of them) and form a closed caliber.
Когда клеть 5 находитс в крайнем положении, отк жваетс зев ручь и заготовка подаетс и поворачиваетс , а также поворачиваетс стержень с оправкой.Во врем рае 9чего хода кле.ти (при квижении ее вправо) вгшки производ т обжатие заготовки. В конце рабочего хода освобожденна от валков труба, а также оправка поворачиваютс . Клеть возвращаетс в исходное положение и осуществл ет при этоы деформацию заготовки. Затем цикл прокатки повтор етс .When the cage 5 is in the extreme position, the throat of the stream is opened and the workpiece is fed and turned, and the rod with the mandrel is rotated. At the end of the working stroke, the tube freed from the rolls and also the mandrel are rotated. The cage returns to its original position and deforms the blank with it. Then the rolling cycle is repeated.
