Description

Technical Field

[0001] This utility model relates to the field of hydraulic cooling equipment technology, specifically a cooling device for an aluminum alloy melting and casting hydraulic system. Background Technology

[0002] The tilting furnace hydraulic station is a key system in the tilting furnace equipment that provides hydraulic power. The tilting furnace hydraulic station uses a motor to drive an oil pump, which draws hydraulic oil from the oil tank and pressurizes it to form high-pressure oil. Then, through various hydraulic control valves, such as directional valves and relief valves, the high-pressure oil is precisely distributed to each hydraulic cylinder of the tilting furnace, thereby driving the piston movement of the hydraulic cylinders to realize the tilting and resetting actions of the tilting furnace.

[0003] The hydraulic oil in the tilting furnace hydraulic station is cooled by water. Due to the frequent use of this hydraulic station (for furnace door lifting and furnace tilting), the temperature is high in summer, and the water cooling effect is poor, failing to achieve the desired cooling effect. The oil temperature can reach 70℃, which leads to frequent equipment failures, frequent replacement of parts, and high maintenance costs. Equipment failures during casting operations can lead to casting failures, increasing manufacturing costs. Utility Model Content

[0004] The purpose of this utility model is to address the problem that the hydraulic oil cooling in the hydraulic station of the tilting furnace is water-cooled.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 5In this embodiment of the present invention, a cooling device for an aluminum alloy casting hydraulic system includes a hydraulic station body 1. A motor 2 and a motor 20 are fixedly installed at the top of the hydraulic station body 1. A reversing valve 4 is provided at the top of the hydraulic station body 1. A switching valve 21 is provided at one end of the reversing valve 4. An oil filter 3 is provided at the top of the hydraulic station body 1. A mounting base 5 is provided at one end of the hydraulic station body 1. A cooling oil body 6 for increasing the cooling effect is fixedly installed at the top of the mounting base 5. A filling pipe 8 is fixedly installed at one end of the cooling oil body 6. An oil drain pipe 9 is fixedly installed at one end of the cooling oil body 6 and on the side of the filling pipe 8.

[0023] The above scheme is adopted: the oil cooling unit 6 is firmly installed on the top of the mounting base 5 by welding, which significantly enhances the cooling effect. The oil filling pipe 8 and the oil drain pipe 9 are respectively installed on one end of the oil cooling unit 6 for convenient oil filling and draining. The advantage of this device is that the structure is reasonable, the components work together to ensure the stable operation of the hydraulic system, and the maintenance and operation are also very convenient. By replacing the oil cooling unit 6 with the original water-cooled cooler, the oil temperature can be controlled below 30℃, the service life of hydraulic station parts is restored to normal (the replacement cycle of the plunger pump can reach half a year), and the equipment failure rate is reduced. A switching valve 21 is set on one end of the reversing valve 4. When one pump fails, the switching valve 21 can be opened to use the other pump to provide power. Motor 1 2 and Motor 2 20 are symmetrically fixed on the top of the hydraulic station body 1, and one end of Motor 1 2 and Motor 2 20 corresponds to a set of plunger pump oil circuits. They can work alternately through the switching valve 21 and the reversing valve 4.

[0024] Reference Figures 1 to 5 The top of the refueling pipe 8 is provided with a filter pipe 10 to reduce the entry of impurities inside the oil into the oil cooler 6. The filter pipe 10 is fixedly installed with a filter screen plate 11 for filtering impurities. The bottom of the filter pipe 10 is provided with a sealing groove 18 to increase the sealing performance. The top of the refueling pipe 8 is fixedly installed with a sealing block 19 that matches the sealing groove 18.

[0025] The above solution involves a filter pipe 10 tightly connected to the top of the refueling pipe 8. Both are made of oil-resistant engineering plastic. Inside the filter pipe 10, a filter screen 11 woven from stainless steel wire is welded and fixed. Its fine mesh effectively intercepts tiny impurities in the oil, significantly reducing the amount of impurities entering the oil cooler 6. A carefully crafted annular sealing groove 18, approximately 5 mm deep, is opened at the bottom of the filter pipe 10. A matching sealing block 19, made of highly elastic rubber, is installed at the corresponding position on the top of the refueling pipe 8, perfectly fitting into the sealing groove 18. The advantages are that the filter pipe 10 and the filter screen 11 ensure the cleanliness of the oil, and the cooperation between the sealing groove 18 and the sealing block 19 ensures excellent sealing at the connection, preventing oil leakage and improving the stability and reliability of the entire cooling device.

[0026] Reference Figures 1 to 5The inside of the refueling pipe 8 is provided with a guide groove 14, and the guide groove 14 is symmetrically provided inside the refueling pipe 8. The inside of the refueling pipe 8 is provided with a limiting groove 15 that is connected to the guide groove 14. A connecting block 12 is fixedly installed inside the filter pipe 10, and the connecting block 12 is symmetrically fixedly installed inside the filter pipe 10. A limiting block 13 that is fixedly fixed to the limiting groove 15 is fixedly installed at one end of the connecting block 12. A limiting slot 16 that limits the limiting block 13 is provided inside the limiting groove 15. A limiting rod 17 that is connected to the refueling pipe 8 and is fixedly fixed to the limiting slot 16 and the limiting block 13 is inserted into one end.

[0027] The above-mentioned design features two symmetrical guide grooves 14 inside the refueling pipe 8, each 5 mm wide and integrally formed from wear-resistant metal. A corresponding limiting groove 15, 3 mm deep, is also symmetrically distributed within the groove. Inside the filter pipe 10, two connecting blocks 12 made of high-strength plastic are symmetrically fixed. One end of each connecting block 12 extends into a limiting block 13, which precisely matches the limiting groove 15. The limiting groove 15 also contains a limiting slot 16 with a depth of 2 mm. At one end of the refueling pipe 8, a metal limiting rod 17 can be easily inserted, penetrating the limiting slot 16 and tightly fixed to the limiting block 13. The advantage of this design is that it simplifies the installation of the filter pipe 10, and the precise limiting structure ensures its stable installation on the refueling pipe 8, effectively preventing loosening and ensuring stable operation of the filtration and sealing functions.

[0028] Reference Figures 1 to 5 The bottom end of the mounting base 5 is rotatably connected to a self-locking universal wheel 7 for easy movement, and the self-locking universal wheel 7 is symmetrically rotatably connected to the bottom end of the mounting base 5.

[0029] The above solution is adopted: the bottom of the mounting base 5 is symmetrically connected to four self-locking casters 7 through a sturdy metal pivot. The casters 7 are made of high-elasticity rubber material, with smooth internal bearings and flexible rotation. The braking device is made of metal material and is easy to operate. The wheels can be locked by simply stepping on the pedal. Its advantages are convenient movement and stable positioning.

[0030] The working principle of this utility model is as follows: When refueling the oil cooler 6 is required, the oil enters the oil cooler 6 through the refueling pipe 8. A filter pipe 10 is installed at the top of the refueling pipe 8, and a filter screen 11 is fixedly installed inside the filter pipe 10. As the oil enters the refueling pipe 8 from the filter pipe 10, impurities in the oil are intercepted by the filter screen 11, thereby reducing the amount of impurities entering the oil cooler 6 and filtering out impurities. When installing the filter pipe 10, a sealing groove 18 is provided at the bottom of the filter pipe 10 to ensure the sealing and stability of the connection. A sealing block 19 that matches the sealing groove 18 is fixedly installed at the top of the refueling pipe 8. The combination of the two increases the sealing of the connection and prevents oil from entering the oil cooler 6. Leakage is prevented. Meanwhile, the inside of the refueling pipe 8 is symmetrically provided with guide grooves 14 and limiting grooves 15 that are connected to them. One end of the connecting block 12 inside the filter pipe 10 is fixedly installed with a limiting block 13. When the filter pipe 10 is installed, the limiting block 13 slides down along the guide groove 14. When it reaches the position of the limiting groove 15, the limiting block 13 can be pushed further into the limiting groove 15. The limiting groove 15 is provided with a limiting slot 16 to limit the limiting block 13. By inserting a limiting rod 17 that passes through the limiting slot 16 and the limiting block 13 into one end of the refueling pipe 8, the limiting and fixing of the filter pipe 10 is achieved, ensuring that the filter pipe 10 is stably installed on the refueling pipe 8 during the refueling process and continuously and effectively filters the oil.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
