Abstract
The utility model discloses a hydraulic system of a transmission station of a rolling mill. The hydraulic system comprises an oil tank. An output loop pipe and a circulation cooling pipe are installed on the oil tank, and the hydraulic output loop pipe is sequentially connected with a pressure pump I, a one-way valve I, a pressure overflow valve and a filter in series and then is connected with an executing component and an energy accumulator in parallel. A circulating pump and a condenser are installed on the circulation cooling pipe. The pressure pump is provided with an overflow pipe and connected with the oil tank. A one-way valve II is arranged on the filter. The hydraulic system is more reasonable, the arranged circulation cooling pipe can guarantee that the temperature of oil in the oil tank is kept reasonable, and the hydraulic system is high in practicability and worthy of popularization.
Description
Technical field
The utility model relates to a kind of hydraulic system, relates in particular to a kind of milling train driving terminal hydraulic system.
Background technique
At present, in milling equipment, all to carry out stamped workpieces with pressure roller, wherein pressure roller is all that the hydraulic system of milling train is carried out operation, but the rolling mill hydraulic system of prior art can be arranged pressure roller and carry out work, it is too high that but the long working of milling train can make the hydraulic oil of hydraulic system stablize, when hydraulic oil is stablized too high, just easily be vaporized, produce bubble, and hydraulic oil can become rarer, will make milling train operation like this time, be short of power, not only easily damage milling train, and cannot ensure quality of product.In addition, in the time that milling train runs into special circumstances and quits work, and the hydraulic oil of high pressure still can pour in milling train at this moment, so just easily damages the hydraulic component of milling train.
Model utility content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of milling train driving terminal hydraulic system.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of milling train driving terminal hydraulic system, comprise fuel tank, output loop pipeline and circulating cooling pipeline are installed on fuel tank, output loop pipeline and circulating cooling pipeline are all circulation loops, wherein, hydraulic pressure output loop pipeline is from the oil outlet of fuel tank bottom, the I pressure pump of connecting successively, I one-way valve, Pressure relief valve and filter, executive component in parallel and accumulator again, finally get back to the upper end of fuel tank, executive component is the milling train of production use, pressure pump is provided with spill pipe and connects and fuel tank, filter is provided with II one-way valve.
Circulating cooling pipeline is also to connect from the bottom of fuel tank, is then installed in series after recycle pump and condenser, and last loop is to fuel tank.
Compared with prior art, the Novel pipeline that the utility model adopts, not only can help milling train to carry out stamping press, and the hydraulic oil of the circulating cooling pipeline arranging in can circulation cooling oil box, allow hydraulic oil maintain rational processing temperature, the accumulator arranging can be in the time that milling train cut be worked, the space that gives unified buffering of hydraulic pressure system, prevents that the hydraulic oil of high pressure from washing out milling train device, and total is reasonable in design, practical, be worthy to be popularized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, model utility is described in detail.
As shown in Figure 1, the milling train driving terminal hydraulic system the utility model proposes, comprise fuel tank 1, on fuel tank 1, there is water level gage, output loop pipeline and circulating cooling pipeline are installed on fuel tank, hydraulic pressure output loop pipeline connect successively I pressure pump 2, I one-way valve 3, Pressure relief valve 4 and filter 5 then executive component in parallel 6 and accumulator 7; Recycle pump 8 and condenser 9 are installed on circulating cooling pipeline; Pressure pump is provided with spill pipe 10 and connects and fuel tank 1; Filter 5 is provided with II one-way valve 11.
In the time of specific works, the hydraulic oil in fuel tank is twitched in pressure pump 2 work, after the adjustment of one-way valve and Pressure relief valve, enter the filtration of carrying out impurity in filter, enter again executive component, wherein executive component is milling train punch roll structure, and as long as providing power to pressure roller, last loop to fuel tank forms hydraulic circulation.Wherein, in the time there is fortuitous event, the punching press cut of milling train and hydraulic system can not stop, now accumulator just can receive from the hydraulic oil of pressure pump output, gives system a buffer space, protects hydraulic component.
Moreover recycle pump 8 can circulate and carry the hydraulic oil in fuel tank 1 always, hydraulic oil can carry out cooling processing by condenser, so just can ensure the reasonable temperature of hydraulic oil in fuel tank.
Above-described embodiment has only been expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
