Description
ца 21 крепитс регулировочный винт 22 механизма привода регулировки закрытой высоты пресса, состо щего из корпуса 23, жестко закрепленного на гильзе 16 и содержащего черв к 24 и черв чное колесо 25, жестко св занное с гайкой 26, взаимодействующей с винтом 22. На винте 22 и в его верхней части установлен кулачок 27, взаимодействующий с конечными выключател ми 28 и 29, св занными с цеп ми управлени двигателем (не показан) механизма привода регулировки. На корпусе 23 механизма привода регулировки установлен кожух 30.The 21 is attached to the adjusting screw 22 of the drive mechanism for adjusting the closed height of the press, consisting of a housing 23 rigidly mounted on the sleeve 16 and containing a screw to 24 and a worm gear 25, which is rigidly connected to the nut 26, which interacts with the screw 22. On the screw 22 and, in its upper part, there is a cam 27 communicating with the limit switches 28 and 29 connected to the motor control circuits (not shown) of the adjustment drive mechanism. A casing 30 is mounted on the housing 23 of the adjustment drive mechanism.
Чеканочный кривошипно-коленный пресс работает следующим образом.Embossing crank-knee press works as follows.
При вращении эксцентрика 10 привода пресса движение передаетс на шатун 9, который воздействует на щарнир 8 и рычаги 6 и 7, которые в свою очередь перемещают иолзун 5, последний совершает возвратно-поступательное движение в направл ющих 4 станины.When the eccentric 10 of the press drive is rotated, the movement is transmitted to the connecting rod 9, which acts on the hinge 8 and the levers 6 and 7, which in turn move the crawler 5, the latter reciprocating in the bed guides 4.
Дл осуществлени регулировки закрытой высоты пресса отключаетс главный привод и включаетс двигатель механизма регулировки закрытой высоты (не показан ), который вращает черв к 25. Последний вращает черв чное колесо 25 и вместе с ним гайку 26, взаимодействующую с винтом 22. Так как гайка 26 в осевом направлении неподвижна, то перемещаетс винт 22 и через налец 21 перемещает сухарь 17, который в свою очередь через пальцы 18, 20 и т гу 19 поворачивает рычаг 15 и вместе с ним эксцентрик 12. Эксцеитрик 12, враща сь, измен ет положение оси подвески рычага 7 и тем самым увеличивает или уменьшает в зависимости от величины эксцентриситета закрыт)ю высоту пресса.In order to adjust the closed height of the press, the main drive is turned off and the motor of the closed height adjustment mechanism (not shown) is turned on, which rotates the screw to 25. The latter rotates the worm gear 25 and with it the nut 26 interacting with the screw 22. As the nut 26 does the axial direction is fixed, then the screw 22 moves and through the nail 21 moves the rusk 17, which in turn through the fingers 18, 20 and pull 19 turns the lever 15 and with it the eccentric 12. The eccentric 12 rotates the position of the suspension axis levers 7 and thereby increases or decreases, depending on the magnitude of the eccentricity, the height of the press is closed.
