Description
Technical field
The utility model relates to a kind of extrusion press hydraulic oil cooling device, particularly a kind of tungsten alloy shaping extruder hydraulic oil cooling device.
Background technique
Tungsten alloy is in extruded process, and general employing fluid press take hydraulic oil as working medium.Because hydraulic oil has reasonable sealing effect, and have lubricating effect, fluid press is widely used, at work, be constantly circulation, the heat produced during work can discharge hydraulic oil in cyclic process, and its temperature can not be risen so high, but too high in ambient temperature, work strong larger time, it is higher that the high temperature that hydraulic pressure does not have can rise.When high temperature, hydraulic oil is thinning, and hydraulic system pressure decreases, and causes the mechanical efficiency of fluid press to reduce.In addition, hydraulic oil, under High Temperature High Pressure effect, is easy to generate the impurity such as oxide with medium effects such as moisture, air, metals, impurity can not only wear and tear each movement parts, and once be stuck in spool or other kinematic pair, will the normal operation of whole system be affected, cause machine to produce fault.In order to ensure the extruded efficiency of tungsten combined pressure, hydraulic oil generally remains on 30 to 40 degrees Celsius.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of cooling unit of high efficiency cooling hydraulic oil, and the hydraulic oil recycled can be made to remain between 30 to 40 degrees Celsius.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of tungsten alloy shaping extruder hydraulic oil cooling device comprises hydraulic oil collection box, the first cooler bin, the second cooler bin, first cooler bin is communicated with hydraulic oil collection box, and the second cooler bin is communicated with the first cooler bin;
Described first cooler bin comprises the first casing, first casing is provided with multiple Cooling Holes, in Cooling Holes, is provided with water cooling box, water cooling box is respectively equipped with water pipe by two ends, hydraulic oil collection box is communicated with the first casing upper end by pipeline, is provided with nozzle in the first casing lower end;
Described second cooler bin comprises the second casing, is provided with inverted U cooling tube in the second casing, and cooling tube is connected with the compressor outside the second casing, is provided with inverted L shape discharger on the second casing two limit, and nozzle to be located in the second casing and above cooling tube.
Further, half arc filter screen is provided with in hydraulic oil collection box.
The utility model has the advantage of, by the water-cooled of the first cooler bin and the refrigerant cools of the second cooler bin, the temperature that effectively can realize hydraulic oil controls, but the water-cooled effect of case can carry out achieve effective control by regulating the temperature of cold water for the first time, if when hydraulic fluid temperature is lower, the temperature of cold water can be relatively higher, if when hydraulic fluid temperature is higher, and suitable lower of the temperature of cold water; Hydraulic oil in first casing is sprayed onto on cooling tube by nozzle by nozzle, can improve cooling comparatively fruit.
Half arc filter screen makes the impurity in hydraulic oil cannot enter the first cooler bin, improves cooling effectiveness (anti-blocking), has also filtered impurity simultaneously and has prevented impurity from reentering extrusion press.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
