Description
(54) ГИДРАВЛИЧЕСКИЙ ПРЕСС(54) HYDRAULIC PRESS
1one
Изобретение относитс к гидравлическим прессам.The invention relates to hydraulic presses.
Известен гидравлический пресс, содержащий колонны, соединенные между собой поперечинами , силовые цилиндры с плунжерами, а также установленный на колоннах стол дл креплени с двух его сторон иструмента.A hydraulic press is known, which contains columns, interconnected crosspieces, power cylinders with plungers, and a table mounted on the columns for fastening the tool on its two sides.
Основным недостатком известного пресса вл етс невозможность получени различных усилий нажима инструмента.The main disadvantage of the known press is the impossibility of obtaining various press forces of the tool.
В предлагаемом прессе с целью изменени частоты срабатывани предусмотрена рама, через которую пропущены колонны, служаща дл креплени на ее внутренней поверхности инструмента, силовые цилиндры смонтированы на наружной поверхности рамы; а их плунжеры выполнены ступенчатыми, воздействующими ступенью большего диаметра на поперечины, соедин ющие колонны, при этом рабочие полости каждой из ступеней соединены с источником питани .In the proposed press, in order to change the frequency of operation, a frame is provided through which the columns are passed, which serves to be mounted on its inner surface of the instrument, the power cylinders are mounted on the outer surface of the frame; and their plungers are made in steps, affecting a step of larger diameter on the cross-pieces connecting the columns, and the working cavities of each of the steps are connected to a power source.
На чертеже изображен предлагаемый пресс.The drawing shows the proposed press.
Пресс содержит колонны 1, пропущенные через раму 2 и соединенные между собой поперечинами 3. Силовые цилиндры 4 расположены на наружных поверхност х рамы, а их плунжеры 5 выполнены ступенчатыми. На колоннах установлен стол 6.The press contains columns 1, passed through frame 2 and interconnected by crossbars 3. Power cylinders 4 are located on the outer surfaces of the frame, and their plungers 5 are made stepped. On the columns set table 6.
Поперечины 3, соединенные с колоннами гайками 7, взаимодействуют с планжерамп 5. На цилиндрах при помощи резьбового соединени закреплены зубчатые кольца 8, наход щиес в зацеплении с черв ками 9, которыми регулирзетс величина рабочего хода обоих плунжеров.The crossbars 3, which are connected to the columns with nuts 7, interact with the Planjeramp 5. On the cylinders, toothed rings 8 are fixed to the cylinders by means of a threaded connection, which are in engagement with the screws 9, which regulate the magnitude of the stroke of both plungers.
Пресс работает следующим образом.The press works as follows.
Через отверстие в цилиндре 4, например через отверстие 10, подаетс жидкость под больщую ступень плунжера, затем узел, состо щий из плунжеров 5, поперечин 3, колонн 1, стола 6, перемещаетс вниз, и в нижней рабочей зоне происходит пластическое формообразование под вли нием силы нажима пресса , котора вл етс произведением величины данной поверхности п давленп жидкости.Through the hole in the cylinder 4, for example through the hole 10, fluid is supplied under the large plunger stage, then the assembly consisting of plungers 5, crossbars 3, columns 1, table 6 is moved downwards, and plastic formation takes place in the lower working area. the pressing force of the press, which is the product of the magnitude of the given surface and the pressure of the liquid.
Затем распределительное устройство (не показано) направл ет жидкость, например, через отверстие 11 под ступень больщего диаметра плунжера, и весь узел поднимаетс , и в верхней рабочей зоне происходит пластическое формообразование под вли нием силы нажима, завис щей от величины данной поверхности плунжера и давлени жидкости, имеющего посто нную величину.A distribution device (not shown) then directs the fluid, for example, through the opening 11 under the step of a larger plunger diameter, and the entire assembly rises, and plastic formation takes place in the upper working area under the influence of the pressing force depending on the size of the plunger surface and pressure liquids having a constant value.
Таким образом, в одном цикле получаем две различные силы нажнма пресса. СоответThus, in one cycle we get two different press nazhm forces. Corresponding to
