Description

Предлагаемое приспособление к парогидравлическим прессам дл  автоматического прекращени  подачи пара в рабочий цилиндр траверсы предназначено дл  ограничени  рабочего давлени  пресса на поковку на определенной высоте, что предохран ет поковку от брака по пережиму .The proposed adaptation to steam-hydraulic presses for automatic cessation of steam supply to the working cylinder of the crosshead is intended to limit the working pressure of the press to the forging at a certain height, which prevents the forging from pinching.

Устройство приспособлени  изобрал ено на чертеже.The device is depicted in the drawing.

При достижении траверсой /пресса во врем  ее опускани  определенной высоты вертикальна  рейка 2, св занна  с траверсой, своим упоpolM 3 открывает кл-апан 4 дистрибутора 5. При этом вода высокого давлени  но напорному трубопроводу 6 устремитс  к гидравлическому цилиндру 7 с диференциальным поршнем 8. Под давлением поступающей воды порщень 8 опускаетс  и штоком 9 воздействует wa серьгу 10, св занную упором 11 с фасонными пластинами 12. Последние своими прорез ми 13 надеты на палец 14, укрепленный в прорези щтока 13 парового .клапана 16. Палец 14 также входит в прорези рычага 17 механизма 18 ручного управлени  прессом.When the crosshead / press reaches a certain height, the vertical rail 2, connected to the crosshead, opens up the distributor Kl 4 with distributor 5 with its crosshead. At the same time, high pressure water rushes to the hydraulic cylinder 7 with a differential piston 8. Under pressure of the incoming water, the piston 8 is lowered and the rod 9 acts on the wa stud 10, connected by the stop 11 with the shaped plates 12. The latter, with their slits 13, are worn on the finger 14, reinforced in the slit of the rod 13 of the steam valve 16. The finger 14 also He goes into the slot 17 of the lever 18 of the manual control mechanism of the press.

Под действием опускающегос  штока 9 фасонные нластинки 12 повернутс , и прорези 13 установ тс  в отвесное положение, совпадающее с прорез ми на штоке 15 и рычаге 17. При этом щток 9 упретс  в щток 15 и посадит паровой клапан 16 на седло, иреодолев сопротивление пара снизу клапана и прекратив тем самым доступ пара в рабочий цилиндр траверсы. Таким образом, рабочее давление на поковку снимаетс . Дл  того, чтобы подготовить пресс к работе, нужно рычаг 17 механизма ручного пресса перевести на обратный ход. При этом прорези фасонных нластин 12 установ тс  в горизонтальное положение и под действием обратного хода поршн  8 клапан 4 дистрибутора закроетс , а траверса подниметс  вверх и цикл работы повторитс .Under the action of the descending rod 9, the shaped bottom plates 12 are rotated and the slots 13 are placed in a plumb position that coincides with the slots on the rod 15 and the lever 17. At the same time, the shanks 9 rest in the shanks 15 and set the steam valve 16 on the saddle, and iodo-vapor vapor resistance valve and thereby stopping the access of steam to the working cylinder of the traverse. Thus, the working pressure on the forging is removed. In order to prepare the press for work, you need to transfer the lever 17 of the manual press mechanism to reverse. At the same time, the slots of the shaped plates 12 are set to a horizontal position, and under the action of the reverse stroke of the piston 8, the distributor valve 4 is closed, and the traverse is lifted upwards and the work cycle is repeated.

Предм ет изобретени SUMMARY OF THE INVENTION

Приспособление к парогидравлическим прессам дл  автоматического прекращени  подачи пара в рабочий цилиндр траверсы при достижении ею определенной высоты при опускании , отличающеес  применением гидравлического цилиндра 7 с диференциальным поршнем 8, больша  ступень которого сообщаетс  сAdaptation to steam-hydraulic presses for automatic cessation of steam supply to the working cylinder of the traverse when it reaches a certain height when lowering, characterized by the use of a hydraulic cylinder 7 with a differential piston 8, a large stage of which communicates with

575 напорным трубопроводом через клапан 4 дистрибутора, открываемый переставным упором 3 траверсы, а мала  ступень всегда сообщена с напорным трубопроводом и св зана штоком 9 .и серьгой 10 с фасонными пластинами 12, надетыми своими прорез ми на укрепленный в штоке парового клапана 16 палец 14, вход щий также в прорези рычага 17 механизма ручного управлени  прессом .575 through the distributor valve 4, opened by adjustable stop 3, the crosshead, and the small stage is always connected to the discharge pipe and connected with the rod 9. And earring 10 with shaped plates 12, wearing their slots on the finger 16 fixed in the stem of the steam valve 16, also included in the slots of the lever 17 of the mechanism for manual control of the press.
