Description

(54) ГИДРАВЛИЧЕСКИЙ ПРЕСС(54) HYDRAULIC PRESS

щих 13 на колоннах. В нижней части корпуса цилиндра расположены по окружности плунжеры 14. На поршневом штоке, в нижней его части, смонтирован тарельчатый упор 15, на который насажена сферическа накладка 16. В нижней части корпуса цилиндра, на его боковой поверхности с нарезкой, посажено зубчатое колесо 17, сопр женное с черв ком 18. Внутри поршн и штока вдоль оси просверлено отверстие, в котором расположен валик 19, а в нижней части - упорный стержень 20, посаженный в штоке при помош,и резьбового соединени и соединенный с валиком. В подвижном столе 12 и в верхней части поршн 7 просверлено отверстие, внутри которого установлен валик 21, взаимодействуюший с валиком 19. В нижней части пресса смонтирован нижний дополнительный тарельчатый упор 22, прикрепленный к корпусу цилиндра при помощи болтов 23, на который насажена накладка 24.13 on the columns. In the lower part of the cylinder body there are plungers 14 circumferentially. On the piston rod, in the lower part, there is mounted a disk support 15, on which a spherical lining 16 is mounted. In the lower part of the cylinder body, a gear wheel 17 is mounted on its side surface with cutting, the worm 18 is conjugated. Inside the piston and the rod, an opening is drilled along the axis, in which the roller 19 is located, and in the lower part there is a stop rod 20, planted in the rod with help, and a threaded joint and connected to the roller. In the movable table 12 and in the upper part of the piston 7, a hole is drilled, inside which a roller 21 is installed, cooperating with the roller 19. In the lower part of the press, an additional bottom disk support 22 is mounted, attached to the cylinder body with bolts 23, onto which a pad 24 is mounted.

Внутри нижнего тарельчатого упора 22 и накладки 24 помещаетс трехходовой золотник 25, к которому по трубопроводам 26 подводитс масло под давлением Р.A three-way spool 25 is placed inside the lower disc support 22 and lining 24, to which oil under pressure P. is supplied via pipelines 26.

Пресс работает следующим образом.The press works as follows.

В камеру под поршнем золотник управлени (не показан) подводит масло под давлением , и поршень вместе с рабочим столом и инструментом начинает рабочий ход, в конце которого происходит операци пластической обработки инструментом. После того, как накладка 16 тарельчатого упора 15 подойдет к колесу 17, масло под давлением подаетс над плунжерами, которые через накладку тарельчатого упора и дополнительный нилспий тарельчатый упор 15 осуществл ют холостой ход поршн , поршневого штока и рабочего стола.In the chamber under the piston, the control spool (not shown) brings the oil under pressure, and the piston together with the working table and the tool begins the working stroke, at the end of which the plastic working operation takes place with the tool. After the pad 16 of the disc support 15 approaches the wheel 17, the pressurized oil is supplied over the plungers, which, through the pad of the disc support and the additional nilspium disc stop 15, idle the piston, piston rod and the worktable.

В конце этого хода стержень 20 удар ет в трехходовой золотник 25, отсека при помоши гидравлического импульса поступление маслаAt the end of this stroke, the rod 20 blows into the three-way spool 25, the compartment with the aid of a hydraulic impulse oil flow

над плунжерами, амортизиру в то же врем силу удара в нижний тарельчатый упор 22. Рабочий ход поршн вверх регулируетс при помощи зубчатого колеса 17 посредством черв ка 18. Ход порщн вниз регулируетс величиной выдвижени из поршневого штока стержн 20 посредством валиков 21 и 19.over the plungers, at the same time, the shock force is absorbed into the lower disc support 22. The upward working stroke of the piston is adjusted by means of a gear wheel 17 by means of a screw 18. The stroke of the piston down is regulated by the amount of extension from the piston rod of rod 20 by means of rollers 21 and 19.
