Abstract
The utility model discloses a hydraulic system of a copper strip pickling line wringer roll. The hydraulic system comprises hydraulic cylinders and the wringer roll. The two hydraulic cylinders are respectively the first hydraulic cylinder and the second hydraulic cylinder. The two hydraulic cylinders are respectively arranged on a hydraulic pipeline at the two ends of the wringer roll and communicated through the hydraulic pipeline. A reducing valve is arranged on the hydraulic pipeline. In the operating process of the wringer roll, when pressure in the hydraulic pipeline is large, the pressure is reduced by the reducing valve, and when the pressure in the hydraulic pipeline is small, the second hydraulic cylinder is started to increase the pressure, and eventually the pressure is controlled within the range that the wringer roll can stably work. The yield is improved, and cost is reduced.
Description
Technical field
The utility model relates to copper strips pickling technical field, especially relates to a kind of hydraulic system of copper strips pickling line squeeze roll.
Background technique
At present, copper strips pickling line squeeze roll when operation, little when large when hydraulic pressure is unstable, affect the quality of production of copper strip surface.
When hydraulic pressure is larger, cause the surface of the fracture of pickling line squeeze roll roller footpath and copper strips to be damaged, affect manufacturing schedule, increase cost of production; Hydraulic pressure hour, causes copper strip surface band water, variable color, and yield rate is low, to copper strips production and quality of product, causes very large impact.
The model utility content
For the prior art deficiency, technical problem to be solved in the utility model is to provide a kind of hydraulic system of copper strips pickling line squeeze roll, stability hydraulic while moving to reach squeeze roll, the purpose that the copper strips yield rate is high.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of hydraulic system of copper strips pickling line squeeze roll, comprise oil hydraulic cylinder and squeeze roll, described oil hydraulic cylinder is two of oil hydraulic cylinder I and oil hydraulic cylinder II, two oil hydraulic cylinders are located at respectively on the hydraulic pipe line at squeeze roll two ends, be connected by hydraulic pipe line between two oil hydraulic cylinders and be provided with reduction valve on this hydraulic pipe line.
Be provided with the pressure transducer of controlling the work of oil hydraulic cylinder II in described hydraulic pipe line.
In the hydraulic pipe line at described squeeze roll two ends, pressure range is 0.4-0.6MP.
The utility model compared with prior art, have the following advantages: the squeeze roll operation, when the pressure in hydraulic pipe line is larger, by reduction valve, pressure is reduced, hour, the oil hydraulic cylinder II starts and improves pressure pressure in hydraulic pipe line, and pressure is controlled in the squeeze roll stable operation range the most at last, improve yield rate, reduce costs.
The accompanying drawing explanation
Below to each width accompanying drawing of this specification, expressed content and the mark in figure are briefly described:
Fig. 1 is the utility model hydraulic system schematic diagram.
Embodiment
Below contrast accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the hydraulic system of this copper strips pickling line squeeze roll, comprise oil hydraulic cylinder and squeeze roll and the hydraulic pipe line that is communicated with oil hydraulic cylinder and squeeze roll, wherein, oil hydraulic cylinder comprises two, is respectively oil hydraulic cylinder I and oil hydraulic cylinder II, and two oil hydraulic cylinder I and oil hydraulic cylinder II are located at the two ends of squeeze roll, by hydraulic pipe line, make hydraulic pressure I and oil hydraulic cylinder II and squeeze roll form the hydraulic system of series connection, on the hydraulic pipe line between oil hydraulic cylinder I and oil hydraulic cylinder II, be provided with reduction valve.
Wherein, be provided with the pressure transducer of controlling the work of oil hydraulic cylinder II in hydraulic pipe line.Hour, the oil hydraulic cylinder II starts and improves pressure pressure in hydraulic pipe line, and pressure is controlled in the squeeze roll stable operation range the most at last.
Reduction valve uses ball-and-spring valve, automatically regulates pressure size in hydraulic pipe line.
By the adjusting of reduction valve and oil hydraulic cylinder II, pressure in the hydraulic pipe line at squeeze roll two ends is controlled in the scope of 0.4-0.6MP.The squeeze roll stability hydraulic, good operating stability, yield rate is high.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
