Description

Известные способы производства труб с высокой точностью по диаметру и толщине стенки, идущих, главным образом, дл  изготовлени  колец ПОДШИПНИКОВ качени , требуют применени  двухвалкового прощивного и трехвалкового ЕЫТЯЛ ИОГО (удлинительного) станов. На трехвалковом выт жном стане гильза прокатываетс  на длинной оправке, перемещающейс  вместе с трубой, котора  затем из прокатаниой трубы извлекаетс .The known methods for producing pipes with high accuracy in diameter and wall thickness, which are mainly used for making rings of rolling BEARINGS, require the use of a two-roll forgiveness and three-roll EYTEL YOGO (extension) mills. In a three-roll exhauster, a sleeve is rolled on a long mandrel moving with the pipe, which is then removed from the rolled pipe.

Предлагаемый комбинированный способ прошивки и выг жки труб на трехвалковом стане позвол ет упростить конструкцию стана и улучщить качество труб за счет совмещени  операций прошнвки и выт жки труб Ei ОДНИХ валках.The proposed combined method of flashing and piping on a three-roll mill allows us to simplify the construction of the mill and improve the quality of the pipes by combining the sweep and drawing operations of the Ei tubes of ONE rolls.

Рабочим органом стана  вл ютс  трн валка и онравка.The working body of the mill is trn roll and onravka.

Калибровка валка нредставл ет собоГ комбинацию калибровки прошивных и выт жных станов.The roll calibration is a combination of calibration of piercing and exhausting mills.

Дл  прокаткп толстостенных труб выт жной уголок калибра выполн етс  в виде кольцевого гребн , переход щего в цилиндрически по сок, предназначенный дл  проглаживанн  прокат нно труб. А дл  прокатки труб с более тонкой стенкой выт жной участок калибра выполн етс  в виде винтового гребн , за которым расположен ц Л ндрический по сок дл  проглаживан 1  трубы.For rolling thick-walled pipes, the caliber exhaust corner is made in the form of an annular ridge, passing into a cylindrical juice, designed for flattened rolled pipes. And for rolling pipes with a thinner wall, the exhaust section of the caliber is made in the form of a screw ridge, behind which is located the center of the juice for ironing 1 pipe.

Оси валков на %;лонеиы к оси прокатки под углом, определ юнип как и на обычных станах осевую подачу заготовкп. Кроме валков могут наклон тьс  иод углом в сторону выхода заготовки или в сторону входа заготовки дл  уменьшени  скольжени  между валком и заготовкой и улучшеии  захвата заготовки валками.Axes of the rolls on%; looney to the axis of rolling at an angle, defines the unit as the axial feed of the billet as in conventional mills. In addition to the rolls, the iodine can be tilted by an angle towards the exit of the workpiece or towards the entrance of the workpiece to reduce the slip between the roll and the workpiece and improve the gripping of the workpiece by the rolls.
