Description
16 и регулировочными болтами 17 и 18, установленными на валу 19 дополнительного привода 20.16 and the adjusting bolts 17 and 18 mounted on the shaft 19 of the additional drive 20.
Устройство работает следующим образом .The device works as follows.
В исходном 1олол ении количество оборотов вариатора подбираетс дл прокатки конкретной заготовки 21 перемещением подвижных щечек 11 и 16 регулировочными болтами 12, 13, 17, 18 на щкивах 10 и 15. In the initial rolling, the number of revolutions of the variator is selected for rolling a concrete billet 21 by moving the movable jaws 11 and 16 by adjusting bolts 12, 13, 17, 18 on the pins 10 and 15.
Путем подачи рабочего тела в полости 22 силовых цилиндров 4 устанавливают плиты 2 с клинь ми 3 в исходное положение и подают заготовку 21 через полые цапфы 7 и пространство между клинь ми 3 на шаг прокатки, затем путе.м подачи рабочего тела в полости 23 силовых цилиндров 4 перемещают клинь 3, удержива заготовку 21 от поворота патроном 24. В результате сил трени , возникающих при прокатке между клинь ми 3 и заготовкой 21 возникает момент, вращающий корпус 1 в подшипниках 8 с определенным количеством оборотов. Такое же количество оборотов сообщаетс корпусу 1 при настройке вариатора и тем самым ликвидируетс момент инерции, создаваемый массой корпуса 1, плит 2 с клинь ми 3, при вращении ихBy feeding the working fluid in the cavity 22 of the power cylinders 4, the plates 2 with the wedges 3 are set to their original position and the workpiece 21 is fed through the hollow trunnions 7 and the space between the wedges 3 to the rolling step, then the working fluid supply in the cavity 23 of the power cylinders 4, the wedge 3 is moved, keeping the workpiece 21 from being rotated by the chuck 24. As a result of the frictional forces that occur when rolling between the wedges 3 and the workpiece 21, a moment occurs that rotates the body 1 in the bearings 8 with a certain number of revolutions. The same number of revolutions is communicated to housing 1 when adjusting the variator and thereby eliminating the moment of inertia created by the mass of housing 1, plates 2 and wedges 3, while rotating them
в процессе прокатки. По завершению перемещени клиньев 2 реверсируют направление потока рабочего тела, подвод его в полости 22 силовых цилиндров 4, и таким образом, возвращают плиты 2 с клинь ми 3 в исходное положение. После возвращени плиты 2 с клинь ми 3 в исходное положение заготовку 21 перемещают вдоль оси на шаг прокатки и снова повтор ют прокатку .in the process of rolling. Upon completion of the movement of the wedges 2, the flow direction of the working fluid is reversed, supplying it in the cavity 22 of the power cylinders 4, and thus returning the plates 2 with the wedges 3 to their original position. After the plate 2 with the wedges 3 has returned to its initial position, the billet 21 is moved along the axis to the rolling step and rolling is repeated again.
Предлагаемое устройство дл поперечно-клиновой прокатки обеспечивает повышение стабильности процесса прокатки.The proposed device for cross-wedge rolling provides increased stability of the rolling process.
