Abstract
The utility model discloses a hydraulic device for a numerical control plate bending roll and relates to the technical field of manufacturing of the numerical control plate bending roll. The hydraulic device comprises a hydraulic oil cylinder (1), heating resistances (2), a fan shell (3) and cooling fans (4). The heating resistances (2) are uniformly arranged on the outer wall of the hydraulic oil cylinder (1). The fan shell (3) is arranged outside the hydraulic oil cylinder (1) and the heating resistances (2). The cooling fans (4) are arranged around the fan shell (3). When the hydraulic oil temperature is excessively low, the hydraulic device can be heated; and when the hydraulic oil temperature is excessively high, the hydraulic device can be cooled. The hydraulic device has a simple structure and a reasonable design and is easy to maintain.
Description
Technical field:
The utility model relates to numerical control plate bending rolls manufacturing technology field, is specifically related to a kind of numerical control plate bending rolls hydraulic pressure installation.
Background technique:
The temperature of hydraulic oil generally is controlled at 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; Machine run speed is unstable, is easy to generate and creeps: after the oily temperature rise, hydraulic system pressure descends; 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 is complicated, and 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.
The model utility content:
The purpose of the utility model provides a kind of numerical control plate bending rolls hydraulic pressure installation, and it is crossed at hydraulic oil temperature and can heat it when low, can be when hydraulic oil temperature is too high to its cooling of lowering the temperature, and simple in structure, reasonable in design, be easy to maintaining.
In order to solve the existing problem of background technique; The utility model is to adopt following technological scheme: it comprises hydraulic jack 1, heating resistor 2, fan hub 3 and cooling fan 4; Hydraulic jack 1 outer wall evenly is provided with heating resistor 2; Fan hub 3 is arranged on the outside of hydraulic jack 1, heating resistor 2, and fan hub 5 around be provided with cooling fan 4.
The principle of the utility model is: hydraulic oil temperature is crossed when low, can heat it through heating resistor 2; When hydraulic oil temperature is too high, can be through cooling fan 4 to its cooling of lowering the temperature, simple in structure.
The utility model is crossed at hydraulic oil temperature and can be heated it when low, can be when hydraulic oil temperature is too high to its cooling of lowering the temperature, and simple in structure, reasonable in design, be easy to maintaining.
Description of drawings:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the right elevation of Fig. 1.
Embodiment:
With reference to Fig. 1-3; This embodiment adopts following technological scheme: it comprises hydraulic jack 1, heating resistor 2, fan hub 3 and cooling fan 4; Hydraulic jack 1 outer wall evenly is provided with heating resistor 2; Fan hub 3 is arranged on the outside of hydraulic jack 1, heating resistor 2, and fan hub 5 around be provided with cooling fan 4.
The principle of this embodiment is: hydraulic oil temperature is crossed when low, can heat it through heating resistor 2; When hydraulic oil temperature is too high, can be through cooling fan 4 to its cooling of lowering the temperature, simple in structure.
This embodiment is crossed at hydraulic oil temperature and can be heated it when low, can be when hydraulic oil temperature is too high to its cooling of lowering the temperature, and simple in structure, reasonable in design, be easy to maintaining.
