Description
Technical field
The present invention relates to numerical control both arms twin-tub stretch benders manufacturing technology field, be specifically related to a kind of numerical control both arms twin-tub stretch benders hydraulic oil temperature controlling device.
Background technique
The temperature of hydraulic oil is generally controlled the scope about 30 ℃～50 ℃ in the hydraulic transmission, the highest should be above 60 ℃.If hydraulic fluid temperature is too high or low excessively, hydraulic system will produce harmful effect, and work is affected.After the oil temperature rise, the viscosity of oil product reduces, and the cohesive force of fluid reduces, and leakage increases, and machine run speed instability is easy to generate and creeps; After the oil temperature rise, hydraulic system pressure descends, and the stability of a system is affected, and has reduced operating accuracy, influences the equipment proper functioning; After the oil temperature rise, the lubricant film attenuation of relative motion surface, the hydraulic element expanded by heating has increased mechanical wear, and the pump valve class component increases wearing and tearing, even is stuck.
In order to reduce hydraulic oil temperature, dispose cooling system in the present hydraulic system, this cooling system structure complexity, volume is bigger, is not easy to maintaining.If it is low that hydraulic oil temperature is spent, then need start preheating earlier, reduce working efficiency, increase the wearing and tearing of machine.
Summary of the invention
The purpose of this invention is to provide a kind of numerical control both arms twin-tub stretch benders hydraulic oil temperature controlling device, it is crossed at hydraulic oil temperature and can heat it when low, can be to its cooling of lowering the temperature when hydraulic oil temperature is too high, and simple in structure, reasonable in design, be easy to maintaining.
In order to solve the existing problem of background technique, the present invention has adopted following technological scheme:
Numerical control both arms twin-tub stretch benders hydraulic oil temperature controlling device of the present invention comprises hydraulic jack 1, circulating pipe 2, feed-water end 3, waterexit end 4, temperature transducer and servovalve, circulating pipe 2 even solderless wrapped connections are in hydraulic jack 1 outer wall outside, and the feed-water end 3 of circulating pipe 2 is arranged at a upper lateral part of hydraulic jack 1, and the waterexit end 4 of circulating pipe 2 is arranged at a side bottom of hydraulic jack 1.
Its principle is: hydraulic oil temperature is crossed when hanging down, can in circulating pipe 2, feed hot water it is heated, when hydraulic oil temperature is too high, can in circulating pipe 2, feed cold water or frozen water to its cooling of lowering the temperature, 4 outflows reserve for other use energy saving to water after the heating through the waterexit end.Its temperature control is by temperature transducer and the control of various servovalve corresponding actions.
For when hydraulic oil temperature is too high, further strengthening radiating effect, also be provided with fan hub 5 and fan 6 in numerical control both arms twin-tub stretch benders hydraulic oil temperature controlling device of the present invention, fan hub 5 is arranged on the outside of hydraulic jack 1, circulating pipe 2, and be provided with fan 6 around the fan hub 5, feed-water end 3 and waterexit end 4 pass from fan hub 5.
Its principle is: when hydraulic oil temperature is too high, not only can in circulating pipe 2, feed cold water or frozen water to its cooling of lowering the temperature, can also open fan 6 and accelerate cooling, and good cooling results, assurance equipment can normal operation.
The beneficial effect of the invention: the present invention crosses at hydraulic oil temperature and can heat it when low, can be to its cooling of lowering the temperature when hydraulic oil temperature is too high, and simple in structure, reasonable in design, be easy to maintaining.When opening fan, heat radiation obtains promoting that cooling effect is strengthened, so cooling effect is better.
