Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, specifically to a hydraulic press with good heat dissipation. Background Technology

[0002] In modern industrial production, hydraulic presses are widely used in metal forming, material pressing and many other processing technologies due to their powerful pressure output capabilities. However, with the continuous improvement of industrial production efficiency and the increasingly stringent requirements for continuous operation of equipment, hydraulic presses face serious heat dissipation problems during long-term operation. In particular, the hydraulic cylinder, as the core component of the hydraulic press to realize pressure conversion and output, generates a lot of heat during its operation due to the frequent flow of hydraulic oil and the friction of mechanical parts.

[0003] In the existing technology, most hydraulic press hydraulic systems do not have heat dissipation devices, making it impossible to accurately and efficiently dissipate heat from the hydraulic cylinders. The hydraulic oil circulation path inside the hydraulic cylinder is complex, making it difficult for heat to be quickly conducted to the outside, resulting in a continuous rise in the temperature of the hydraulic cylinder. Excessive temperature not only reduces the viscosity of the hydraulic oil, thereby reducing the transmission efficiency and control accuracy of the hydraulic system, but also accelerates the aging of seals, causing hydraulic oil leakage and affecting the stability and service life of the equipment.

[0004] According to the description in the patent announcement (CN221873333U) of a hydraulic press for pressing stacked plates, the hydraulic press for pressing stacked plates includes a "worktable, control console" etc., to achieve the pressing work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This hydraulic press for pressing stacked plates utilizes a worktable and control console to perform the pressing operation. During operation, the press uses hydraulic cylinders to drive the pressure plates to move up and down. However, these cylinders lack a cooling structure for heat dissipation. The complex circulation path of the hydraulic oil inside the cylinder makes it difficult for heat to be quickly conducted to the outside, causing the cylinder temperature to rise continuously. Excessive temperature will reduce the viscosity of the hydraulic oil, thereby reducing the transmission efficiency and control accuracy of the hydraulic system. Therefore, this hydraulic press needs to be improved. Utility Model Content

[0008] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic press with good heat dissipation, comprising a base, a hydraulic press body fixedly connected to the top of the base, a hydraulic cylinder fixedly connected to the top of the hydraulic press body, a first heat dissipation mechanism provided on the top of the hydraulic press body, and a second heat dissipation mechanism provided on the right side of the top of the base.

[0009] The first heat dissipation mechanism includes a protective frame, which is fixedly connected to the top of the hydraulic press body. A heat dissipation frame is fixedly connected to the top of the protective frame, and a servo motor is fixedly connected to the top of the heat dissipation frame. A rotating shaft is fixedly connected to the bottom of the servo motor, and fan blades are fixedly connected to the periphery of the rotating shaft. A fixing frame is fixedly connected to the inner side of the protective frame, and a heat-conducting pipe is fixedly connected inside the fixing frame. A water tank is fixedly connected to the top of the rear end of the heat-conducting pipe, and a support platform is fixedly connected to the bottom of the water tank. The support platform is fixedly connected to the rear side of the hydraulic press body. First heat dissipation fins are fixedly connected to the left and right sides of the water tank, and a water pump is fixedly connected to the periphery of the heat-conducting pipe.

[0010] Preferably, the heat dissipation frame has heat dissipation holes inside, and the heat dissipation holes are circular to facilitate the dissipation of heat inside the protective frame.

[0011] Preferably, the rotating shaft is rotatably connected inside the heat dissipation frame, and the bottom front side of the water tank is fixedly connected to the bottom rear end of the heat pipe, so that the fan blades can be driven to work by the rotating shaft.

[0012] Preferably, the protective frame is located around the hydraulic cylinder, and the heat-conducting pipe is located inside the protective frame and extends through the interior of the protective frame, so as to absorb the heat generated by the hydraulic cylinder during operation through the heat-conducting pipe.

[0013] Preferably, a water inlet pipe is fixedly connected to the top of the water tank, and a first sealing cap is threadedly connected to the outside of the water inlet pipe. The water pump is fixedly connected to the top of the support platform, so that the coolant in the water tank can be circulated in the heat conduction pipe through the water pump.

[0014] Preferably, the second heat dissipation mechanism includes an oil tank, which is fixedly connected to the top right side of the base. An oil supply pipe is fixedly connected to the left side of the oil tank. The oil supply pipe is fixedly connected to the right side of the hydraulic cylinder.

[0016] Compared with the prior art, this utility model provides a hydraulic press with good heat dissipation, which has the following beneficial effects:

[0017] 1. This hydraulic press with excellent heat dissipation features a primary heat dissipation mechanism. When the press is in use, the connection between the water tank and water pump ensures efficient circulation of coolant within the heat-conducting pipes. These pipes remove heat from the vicinity of the hydraulic cylinders, providing water-cooled cooling. Simultaneously, a servo motor drives the fan blades, generating forced convection and accelerating airflow to quickly remove heat generated by the hydraulic cylinders. This heat rises and is expelled through the heat dissipation holes inside the heat sink frame, further cooling the coolant. The heat-conducting pipes, located inside and penetrating the protective frame, effectively absorb heat generated by the hydraulic cylinders. The protective frame, located around the hydraulic cylinders, protects critical components like the cylinders from external interference. When the coolant circulates from the heat-conducting pipes into the water tank, heat exchange occurs through the first heat sink fins on both sides of the tank, further enhancing the cooling effect on the hydraulic cylinders. The water inlet pipe and matching first sealing cap on the top of the water tank facilitate coolant replenishment.

[0018] 2. This hydraulic press with good heat dissipation has a second heat dissipation mechanism. When the hydraulic press body is in use, the hydraulic pump draws hydraulic oil from the oil tank and delivers it to the hydraulic cylinder through the oil pipeline for hydraulic operation. The second and third heat dissipation fins on the right side and front and rear sides of the oil tank increase the heat dissipation area and can dissipate the hydraulic oil in the oil tank.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a hydraulic press with good heat dissipation, including a base 1, a hydraulic press body 2 fixedly connected to the top of the base 1, a hydraulic cylinder 5 fixedly connected to the top of the hydraulic press body 2, a first heat dissipation mechanism 3 provided on the top of the hydraulic press body 2, and a second heat dissipation mechanism 4 provided on the right side of the top of the base 1.

[0032] The first heat dissipation mechanism 3 includes a protective frame 31, which is fixedly connected to the top of the hydraulic press body 2. A heat dissipation frame 32 is fixedly connected to the top of the protective frame 31. A servo motor 33 is fixedly connected to the top of the heat dissipation frame 32. A rotating shaft 37 is fixedly connected to the bottom of the servo motor 33. A fan blade 38 is fixedly connected to the periphery of the rotating shaft 37. A fixing frame 36 is fixedly connected to the inner side of the protective frame 31. A heat conduction pipe 35 is fixedly connected inside the fixing frame 36. A water tank 34 is fixedly connected to the top of the rear end of the heat conduction pipe 35. A support platform 391 is fixedly connected to the bottom of the water tank 34. The support platform 391 is fixedly connected to the rear side of the hydraulic press body 2. First heat dissipation fins 39 are fixedly connected to the left and right sides of the water tank 34. A water pump 392 is fixedly connected to the periphery of the heat conduction pipe 35.

[0033] The heat dissipation frame 32 has heat dissipation holes inside, and the heat dissipation holes are circular, so that the heat inside the protective frame 31 can be discharged through the heat dissipation holes. The rotating shaft 37 is rotatably connected to the inside of the heat dissipation frame 32. The bottom front side of the water tank 34 is fixedly connected to the bottom rear end of the heat conduction pipe 35, so that the fan blade 38 can be driven to work through the rotating shaft 37.

[0034] The protective frame 31 is located around the hydraulic cylinder 5, and the heat conduction pipe 35 is located inside the protective frame 31 and extends through the interior of the protective frame 31, so that the heat generated by the hydraulic cylinder 5 during operation can be absorbed through the heat conduction pipe 35.

[0035] A water inlet pipe 393 is fixedly connected to the top of the water tank 34. A first sealing cap 394 is threadedly connected to the outside of the water inlet pipe 393. A water pump 392 is fixedly connected to the top of the support platform 391, so that the coolant in the water tank 34 can be circulated in the heat conduction pipe 35 through the water pump 392.

[0036] Example 2

[0037] Please see Figure 1-6 Furthermore, based on Embodiment 1, the second heat dissipation mechanism 4 includes an oil tank 41, which is fixedly connected to the top right side of the base 1. An oil supply pipe 45 is fixedly connected to the left side of the oil tank 41. The oil supply pipe 45 is fixedly connected to the right side of the hydraulic cylinder 5. A hydraulic pump 44 is fixedly connected to the periphery of the oil supply pipe 45. The hydraulic pump 44 is fixedly connected to the top of the base 1. A second heat sink 42 is fixedly connected to the right side of the oil tank 41. A third heat sink 43 is fixedly connected to the front and rear sides of the oil tank 41.

[0038] An oil injection pipe 46 is fixedly connected to the top of the oil tank 41. A second sealing cap 47 is threadedly connected to the outside of the oil injection pipe 46, which facilitates the addition of hydraulic oil to the oil tank 41 through the oil injection pipe 46.

[0039] In actual operation, when this device is in use, when the hydraulic cylinder 5 of the hydraulic press body 2 generates heat during use, the coolant in the water tank 34 is transported to the heat conduction pipe 35 by the water pump 392, and then returns to the water tank 34 through the top of the rear end of the heat conduction pipe 35, realizing the circulation of coolant in the heat conduction pipe 35. The heat conduction pipe 35 can carry away the heat near the hydraulic cylinder 5 for water cooling. At the same time, the servo motor 33 drives the fan blade 38 to rotate, generating forced convection, accelerating the air flow, and quickly carrying away the heat generated by the hydraulic cylinder 5 during operation. The heat moves upward and is discharged through the heat dissipation holes inside the heat dissipation frame 32, which can also dissipate heat from the coolant, thus achieving air cooling for the hydraulic cylinder 5.

[0040] The heat pipe 35 is located inside the protective frame 31 and penetrates the interior of the protective frame 31, which can fully absorb the heat generated by the hydraulic cylinder 5. The protective frame 31 is located outside the hydraulic cylinder 5, protecting the hydraulic cylinder 5 and other key components from external interference. When the coolant in the heat pipe 35 circulates into the water tank 34, it uses the first heat sink 39 on both sides of the water tank 34 to exchange heat, further dissipating the coolant and further improving the heat dissipation effect on the hydraulic cylinder 5. The heat dissipation effect on the hydraulic cylinder 5 is improved by combining air cooling and water cooling. The water filling pipe 393 on the top of the water tank 34 and the matching first sealing cap 394 make it convenient for the staff to add coolant.

[0041] When the hydraulic press body 2 is in use, the hydraulic pump 44 draws hydraulic oil from the oil tank 41 and delivers it to the hydraulic cylinder 5 through the oil delivery pipe 45 for hydraulic operation. The second heat sink 42 and the third heat sink 43 on the right side and front and rear sides of the oil tank 41 can increase the heat dissipation area of ​​the oil tank 41 and dissipate the heat of the hydraulic oil in the oil tank 41, quickly removing the heat from the hydraulic oil. The oil filling pipe 46 and the second sealing cover 47 on the top of the oil tank 41 are designed to facilitate the replenishment of hydraulic oil.

[0042] The hydraulic press body 2 is existing technology, and those skilled in the art are well aware of the specific operating steps and usage methods of this equipment; therefore, it will not be described in detail in this case.
