Utility model content
Utility model object of the present utility model is: provide one with chamber Double Tops hydraulic press, it can be in same set of hydraulic control system, completes controlling in satisfactory to both parties taking blame for others in same cavity.
For completing above-mentioned utility model object, the utility model is achieved in that a kind of with chamber Double Tops hydraulic press, it is characterized in that: on the cavity being communicated with, be provided with two push rods, be provided with balance pipe in the middle of cavity, described two cavitys that separated by balance pipe are independently controlled separately; Be respectively equipped with two fuel feed holes and two-way oil outlet, two independently cavity be respectively equipped with a topping up hole; Described topping up hole is connected to independently topping up control part, and topping up control section is connected to the trunk pipeline of hydraulic circuit; On the in-line of two bodies and fuel-displaced pipeline, be respectively equipped with a balance oil circuit part.The utility model is realized in same hydraulic cavities and being realized two controls up and down of taking blame for others, and can complete from technique scheme, and when lifting on a cylinder, another cylinder body is realized lifting on oppositely of equilibrant force in the effect of same power.In realizing separately this spline structure, we also increase topping up hole, can realize twin-tub in the same way with lifting motion.
Above-mentioned technical scheme is improved further to described topping up control section control two-way charging line; Two described flow liquid pipelines are cascaded by the control of a separatory flow valve.Be provided with two storages at topping up control section and press storehouse, two storages are pressed between storehouse and are provided with solenoid directional control valve, and solenoid directional control valve one tunnel connects storage and presses storehouse, presses storehouse to be out connected to afterwards implementation of port by storage, and another road takes back road.
Hydraulic oil by main pipeline out after, be divided into two-way, a road connects topping up control section, another road connects balance portion; On entering, before oil circuit balance portion and lower oil way balance part, two parts access respectively an independently storage pressure storehouse, press on storehouses and are incorporated to respectively a solenoid directional control valve two storages, and two electromagnetic switch Hou Yi roads are interconnected, and another road takes back road.
Described lower balance oil circuit is to be made up of two-way oil circuit, and the first via connects reversal valve through bunker, and reversal valve one tunnel connects ground connection after two return tanks, and another road of reversal valve directly takes back ground; The second tunnel connects reversal valve after bunker again, reversal valve one tunnel ground connection, and another road takes back working connection.
Described upper balance portion is that access increases part after storehouse is pressed in a storage; A pressure detecting table of access in parallel before storehouse is pressed in access storage.
Described upper balance portion and lower balance portion accessed one before cut-in pressure cylinder increases oil circuit, and described increase oil circuit is to seal in a storage to press storehouse, presses the two ends in storehouse to be incorporated to a valve and individual magnetic valve one by one in storage; Magnetic valve Yi road takes back main line, another road ground connection.
The utility model, in same cavity, completes the flexible of two kinds different directions; And two to pressure keep one to, and in needs, jack-up and with entering to shrink when can realizing two tops, more flexible than general hydraulic means.
Figure of description
Fig. 1 is hydraulic schematic diagram of the present utility model.
The specific embodiment
For the advantage of further description utility model, do the explanation of carrying out more in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of with chamber Double Tops hydraulic press, on the cavity 12 being communicated with, be provided with two push rods 13,14, in the middle of cavity 12, be provided with balance pipe, described two cavitys that separated by balance pipe are independently controlled separately; Be respectively equipped with two fuel feed holes and two-way oil outlet, two independently cavity be respectively equipped with a topping up hole; Described topping up hole is connected to independently topping up control part 11, and topping up control section is connected to the trunk pipeline of hydraulic circuit; On the in-line of two bodies and fuel-displaced pipeline, be respectively equipped with a balance oil circuit part 3,4.
This balance oil circuit part is for being divided into two-way; before upper oil circuit balance portion 3 and lower oil way balance part 4, two parts access respectively an independently storage pressure storehouse 1, press on storehouses and are incorporated to respectively a solenoid directional control valve two storages; two electromagnetic switch Hou Yi roads are interconnected, and another road takes back road; Lower balance oil circuit 4 is to be made up of two-way oil circuit, and the first via connects reversal valve 21 through bunker, and reversal valve one tunnel connects ground connection after two return tanks, and another road of reversal valve directly takes back ground; The second tunnel 23 connects reversal valve 22 again after bunker, reversal valve one tunnel ground connection, and another road takes back working connection.Described upper balance portion is that access increases part 5,6 after storehouse is pressed in a storage; A pressure detecting table 3 of access in parallel before storehouse is pressed in access storage.Lower balance portion accessed one before cut-in pressure cylinder increases oil circuit 8,7, and described increase oil circuit is to seal in a storage to press storehouse, presses the two ends in storehouse to be incorporated to a valve and a magnetic valve in storage; Magnetic valve Yi road takes back main line, another road ground connection.So just, formed the oil circuit of a upper and lower balance, must control the balance on upper and lower four road binders roads in this process, after equilibrium process, setting corresponding pressure at back segment increases or step-down, presses equilibrium of forces thereby realize two cylinders.
For topping up hole, his effect is, be combined with original upper balanced controls or lower balanced controls, and two motions in the same way of changing, concrete function mode is such: described topping up control section control two-way charging line; Two described flow liquid pipelines are cascaded by the control of a separatory flow valve.Be provided with between storage pressure storehouse, 9, two, two storage pressure storehouses and be provided with solenoid directional control valve at topping up control section 11, solenoid directional control valve one tunnel connects storage pressure storehouse, is out connected to afterwards implementation of port by storage pressure storehouse, and another road takes back road.In operation, Double Tops cylinder is being received after the order of while jack-up, and topping up control section starts topping up, and coordinates upper balance oil circuit part, completes topping up, at this moment, and two common jack-up of taking blame for others.
