Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for regulating the temperature of hydraulic press oil. Background Technology

[0002] A hydraulic press is a machine that uses liquid as its working medium and is designed based on Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the main body, the power system, and the hydraulic control system. The main body includes structural components such as the frame, cylinders, and pistons. Hydraulic oil temperature refers to the temperature of the hydraulic oil within the hydraulic system. The temperature of the hydraulic oil is one of the important indicators of the hydraulic press system's operating condition. It is affected by various factors, including the workload, working time, ambient temperature, and the heat transfer performance of the oil pipelines. However, during operation, the hydraulic oil temperature rises, which can cause the hydraulic press to malfunction. A cooling device is a means to cool the hydraulic oil.

[0003] A search revealed CN211314736U, which discloses a cooling device for a hydraulic press used in the production of shaped refractory materials. This device utilizes a double-layered, U-shaped heat exchange tube design to increase heat exchange in the hydraulic oil and improve cooling efficiency. A semiconductor refrigeration chip helps maintain a low temperature in the coolant. However, the coolant in the pipes of this device is stagnant, and the device can only cool the coolant inside the cooling tank. This results in the coolant in the pipes inside the tank not receiving timely cooling, leading to heat accumulation and poor cooling performance of the hydraulic press. Therefore, we propose a cooling device for regulating the oil temperature of a hydraulic press. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for regulating the temperature of hydraulic press oil.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a cooling device for regulating the temperature of hydraulic press oil, comprising a hydraulic press oil tank, an observation window fixed at one end of the hydraulic press oil tank, an oil inlet slidably installed at the upper end of the hydraulic press oil tank, a fixing plate fixed at the other end of the hydraulic press oil tank, a cooling box installed at the upper end of the fixing plate, a partition fixed inside the cooling box, a liquid inlet slidably installed on one side of the upper end of the partition, a first dustproof box fixed on one side of the upper end of the cooling box, an intake fan provided inside the first dustproof box, an exhaust fan provided on one side of the inner side of the first dustproof box, a second dustproof box fixed on one side of the first dustproof box, connecting pipes installed on both sides of the cooling box, pipe joints installed on the connecting pipes, a circulation pipe provided inside the pipe joint, a check valve and a circulation pump respectively provided on the circulation pipe, a heat-conducting plate penetrating through the other side of the upper end of the partition, and a drain port installed at one end of the cooling box.

[0006] Preferably, the cooling box is located directly above the fixed plate, and one end of the cooling box is in contact with the hydraulic press oil tank.

[0007] Preferably, both the intake fan and the exhaust fan are located inside the first dustproof box, with the intake fan positioned directly above the heat-conducting plate.

[0008] Preferably, the circulation pipe passes through the hydraulic oil tank and is distributed at the lower end and the top of the hydraulic oil tank.

[0009] Preferably, a threaded post is fixed at the lower end of the cooling box, a nut is movably installed on the threaded post, support blocks are installed at the four corners of the lower end of the fixed plate, a bidirectional screw is provided through one side of one end of the support block, a sliding post is provided through one side of the bidirectional screw at the other end, and a first limiting plate and a second limiting plate are respectively provided on both sides of the bidirectional screw.

[0010] Preferably, one end of the threaded post passes through the fixed plate, and the threaded post is slidably connected to the fixed plate, and the number of the threaded posts is two.

[0011] Preferably, one end of the sliding column passes through the first limiting plate and the second limiting plate, and the sliding column is slidably connected to both the first limiting plate and the second limiting plate.

[0012] By employing the above technical solution, the coolant inside the cooling tank can flow rapidly in one direction and circulate through the cooperation of a circulating pump, circulating pipes, check valve, and connecting pipes. Then, the heat-conducting plate absorbs heat from the coolant inside the cooling tank, cooling it down. The intake and exhaust fans work together to cool the heat-conducting plate and circulate the air inside the first dustproof box, allowing the heat-conducting plate to continuously absorb heat. The cooling device used to regulate the hydraulic press oil temperature drives the coolant inside the cooling tank to circulate, allowing the coolant to continuously absorb heat from the hydraulic press oil tank, thus improving the overall cooling effect.

[0013] By adopting the above technical solution, the cooling box and the fixed plate can be fixed by the cooperation of the threaded column and the nut. Then, by the cooperation of the double screw and the sliding column, the first limit plate and the second limit plate can move to both sides and limit the nut, so that the nut will not rotate when the hydraulic press oil tank is in use. The cooling device used to regulate the hydraulic press oil temperature can limit the nut, so that the cooling box will not detach from the fixed plate when the hydraulic press oil tank is used for a long time.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: a cooling device for regulating the temperature of hydraulic press oil, including a hydraulic press oil tank 1, an observation window 2 fixed to one end of the hydraulic press oil tank 1, an oil inlet 3 slidably installed on the upper end of the hydraulic press oil tank 1, a fixing plate 4 fixed to the other end of the hydraulic press oil tank 1, a cooling box 5 installed on the upper end of the fixing plate 4, a partition 6 fixed to the inner side of the cooling box 5, a liquid inlet 7 slidably installed on one side of the upper end of the partition 6, and a first dustproof box 8 fixed to one side of the upper end of the cooling box 5. An intake fan 9 is installed inside the first dustproof box 8. An exhaust fan 10 is installed on one side of the first dustproof box 8. A second dustproof box 11 is fixed on one side of the first dustproof box 8. Connecting pipes 12 are installed on both sides of the cooling box 5. Pipe joints 13 are installed on the connecting pipes 12. A circulation pipe 14 is installed inside the pipe joint 13. A check valve 15 and a circulation pump 16 are installed on the circulation pipe 14. A heat conduction plate 17 is installed through the other side of the upper end of the partition 6. A drain port 18 is installed at one end of the cooling box 5.

[0022] The cooling box 5 is located directly above the fixed plate 4, and one end of the cooling box 5 is in contact with the hydraulic oil tank 1.

[0023] Both the intake fan 9 and the exhaust fan 10 are located inside the first dustproof box 8, and the intake fan 9 is located directly above the heat conduction plate 17.

[0024] The circulation pipe 14 passes through the hydraulic oil tank 1, and the circulation pipe 14 is distributed at the lower end of the hydraulic oil tank 1 and the top of the hydraulic oil tank 1.

[0025] Specifically, oil is injected into the hydraulic press oil tank 1 by opening the oil inlet 3. After the oil filling is complete, the process is stopped through the observation window 2, and the oil inlet 3 is returned to its original position. Then, coolant is injected into the cooling tank 5 by opening the liquid inlet 7. After the injection is complete, the process is stopped, and the liquid inlet 7 is returned to its original position. When cooling of the oil inside the hydraulic press oil tank 1 is required, the circulation pump 16 is started, causing the coolant to flow through the connecting pipe 12 into the circulation pipe 14. The coolant then flows from the other end into the cooling tank 5, thus forming a circulation. As the coolant passes through the hydraulic press oil tank 1, it absorbs the oil temperature inside, cooling the oil. When the coolant reaches the top of the hydraulic press oil tank 1... The coolant is cooled by external natural wind, and the heat-conducting plate 17 absorbs heat from the coolant returning to the cooling tank 5. Then, the intake fan 9 and exhaust fan 10 are activated, so that the intake fan 9 draws in fresh air from the outside and dissipates heat from the heat-conducting plate 17, allowing the heat-conducting plate 17 to continuously absorb heat from the coolant. At this time, the exhaust fan 10 will expel the hot air that has been dissipated from the first dust box 8, so that the coolant can continuously cool the oil temperature inside the hydraulic press oil tank 1. In addition, with the cooperation of the check valve 15, the coolant is prevented from flowing back and always flows in the same direction. The cooling device used to regulate the hydraulic press oil temperature can drive the coolant inside the cooling tank 5 to circulate, so that the coolant can continuously absorb the oil temperature inside the hydraulic press oil tank 1, improving the overall cooling effect.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a cooling device for adjusting the oil temperature of a hydraulic press. A threaded column 19 is fixed at the lower end of the cooling box 5, and a nut 20 is movably installed on the threaded column 19. Support blocks 21 are installed at the four corners of the lower end of the fixing plate 4. A bidirectional screw 22 is provided through one side of one end of the support block 21, and a sliding column 23 is provided through one side of the bidirectional screw 22 at the other end. A first limiting plate 24 and a second limiting plate 25 are respectively provided on both sides of the bidirectional screw 22.

[0028] One end of the threaded post 19 passes through the fixed plate 4, and the threaded post 19 is slidably connected to the fixed plate 4. There are two threaded posts 19.

[0029] One end of the sliding column 23 passes through the first limiting plate 24 and the second limiting plate 25, and the sliding column 23 is slidably connected to both the first limiting plate 24 and the second limiting plate 25.

[0030] Specifically, when the cooling box 5 needs to be installed, it is placed on the fixing plate 4, and the threaded post 19 below the cooling box 5 passes through the fixing plate 4. Then, the nut 20 is tightened to fix the cooling box 5 to the fixing plate 4. Then, the double-acting screw 22 is rotated clockwise to drive the first limiting plate 24 and the second limiting plate 25 to move to both sides, so that the first limiting plate 24 and the second limiting plate 25 limit the nuts 20 on both sides. Conversely, the rotation is canceled. When the hydraulic press oil tank 1 is in use, it will vibrate, and the vibration will cause the nut 20 to rotate. When the nut 20 rotates, it will be blocked by the first limiting plate 24 and the second limiting plate 25, so that the cooling box 5 and the fixing plate 4 will not separate. The cooling device used to regulate the hydraulic press oil temperature can limit the nut 20, so that the cooling box 5 will not separate from the fixing plate 4 when the hydraulic press oil tank 1 is used for a long time.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
