Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic devices, in particular to a hydraulic device with an integrated auxiliary oil tank. Background Art

[0002] Hydraulic systems are primarily used for press forming. For example, in wheel hub production, the raw material is placed on a lower die, and the upper die presses down on the material, shaping it into the wheel hub according to the shapes of the upper and lower dies. The hydraulic system's pressure comes from a cylinder, so an oil tank is required within the system to supply the oil. Over time, the cylinder will contain impurities such as metal debris, necessitating the draining and filtering of the oil, followed by the refilling of the filtered oil into the tank. This is a complex process. Utility Model Content

[0005] After adopting the above structure, the utility model has the following advantages: since the main oil tank is connected with the auxiliary oil tank, the oil in the main oil tank can flow into the auxiliary oil tank regardless of whether the hydraulic device is working or on standby, and in the working state, the oil first passes through the cooling zone and is cooled by the cooling component and then flows into the sedimentation zone. Since the width of the sedimentation zone gradually decreases from top to bottom, the density of impurities in the oil is greater than that of the oil, the impurities will settle at the bottom of the sedimentation zone, and the oil can return to the main oil tank from the oil suction zone under the action of the oil pump.

[0009] As an improvement, the connection port between the cooling zone and the main oil tank is located above the cold water pipe; this structure ensures that the oil entering the cooling zone from the main oil tank can be fully cooled through the cold water pipe, thereby improving the cooling effect.

[0010] As an improvement, the lower part of the left end surface of the auxiliary fuel tank is arranged in the vertical direction, and the lower part of the right end surface of the auxiliary fuel tank is inclined from top to bottom to the left or right, and the sedimentation area is formed between the lower part of the left end surface of the auxiliary fuel tank and the lower part of the right end surface of the auxiliary fuel tank; with this structure, the sedimentation area is directly formed by the auxiliary fuel tank structure, which has the advantage of simple structure.

[0011] As an improvement, two front and rear baffles are connected in the sedimentation area, and each baffle is tilted from top to bottom toward the other baffle. With this structure, the two tilted baffles guide the precipitated impurities, helping the impurities to settle at the bottom of the sedimentation area, making the sedimentation area wide at the top and narrow at the bottom, so that the sediment is concentrated in the lower part, which facilitates the discharge of the sediment and improves the sedimentation effect.

[0012] As an improvement, an air filter is connected to the top of the auxiliary fuel tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is a detailed description of a hydraulic device with an integrated auxiliary oil tank according to the present invention in conjunction with the accompanying drawings.

[0017] like Figures 1 to 2As shown, a hydraulic device with an integrated auxiliary oil tank includes a device body 1, a main oil tank 2 and an auxiliary oil tank 3. The main oil tank 2 and the auxiliary oil tank 3 are both connected to the device body 1. The main oil tank 2 is a prior art and will not be described here. The auxiliary oil tank 3 is located outside the device body 1. Figure 1 As shown, an oil chamber 4 is provided in the auxiliary oil tank 3, and the oil chamber 4 includes a cooling zone 41, an oil suction zone 42 and a sedimentation zone 43. A partition 5 is provided in the auxiliary oil tank 3 along the vertical direction, and the upper end of the partition 5 is connected to the top end of the auxiliary oil tank 3, and the front and rear ends of the partition 5 are connected to the front and rear inner walls of the auxiliary oil tank 3. The partition 5 separates the cooling zone 41 and the oil suction zone 42 on the left and right sides of the partition 5, or in some other embodiments, the partition 5 is composed of several blocks, and the several blocks of partitions 5 are combined to form the cooling zone 41, thereby separating the cooling zone 41 from the oil suction zone 42 laterally.

[0018] like Figure 1 As shown, a sedimentation area 43 is formed between the lower end of the partition 5 and the bottom end of the auxiliary oil tank 3. The sedimentation area 43 is connected to the cooling area 41 and the oil suction area 42. That is to say, the cooling area 41 can only be connected to the oil suction area 42 through the sedimentation area 43. The cooling area 41 is connected to the main oil tank 2. Specifically, an oil return area 14 is formed on the upper part of the cooling area 41. The cooling area 41 is connected to the main oil tank 2 through the oil return area 14. A cooling assembly is provided in the cooling area 41. The cooling assembly includes several cold water pipes 9 arranged in the cooling area 41 in a vertical direction, and a water inlet 10 and a water outlet 11 connected to the cold water pipe 9 are provided on the auxiliary oil tank 3. The connection port of the cooling area 41 and the main oil tank 2 is located above the cold water pipe 9.

[0019] like Figure 2 As shown, the auxiliary oil tank 3 is connected to several oil pumps 6 for pumping the oil in the oil suction area 42 back to the main oil tank 2. The oil inlet of the oil pump 6 is connected to the oil suction area 42. The width of the sedimentation area 43 gradually decreases from top to bottom. A drain outlet 7 is provided at the bottom of the sedimentation area 43. The drain outlet 7 is detachably connected to a drain plug 8. Specifically, the drain plug 8 is threadedly connected to the drain outlet 7.

[0020] like Figure 1 As shown, the lower portion of the left end surface of the auxiliary tank 3 is arranged in the vertical direction, and the lower portion of the right end surface of the auxiliary tank 3 is inclined from top to bottom to the left or right side. In this embodiment, it is inclined to the left side. The sedimentation area 43 is formed between the lower portion of the left end surface of the auxiliary tank 3 and the lower portion of the right end surface of the auxiliary tank 3; Figure 2 As shown, two baffles 12 are connected to the sedimentation area 43, and each baffle 12 is tilted from top to bottom toward the other baffle 12. An air filter 13 is connected to the top of the auxiliary fuel tank 3.

[0021] Since the main oil tank 2 is connected to the auxiliary oil tank 3, the oil in the main oil tank 2 can flow into the auxiliary oil tank 3 regardless of whether the hydraulic device is working or on standby. In the working state, the oil first passes through the return oil area 14 and the cooling area 41 to be cooled by the cooling component and then flows into the sedimentation area 43. Since the width of the sedimentation area 43 gradually decreases from top to bottom, the density of impurities in the oil is greater than that of the oil, the impurities will settle at the bottom of the sedimentation area 43, and the oil can return to the main oil tank 2 from the oil suction area 42 under the action of the oil pump 6. It is only necessary to open the drain port 7 regularly to discharge impurities. Regardless of whether the hydraulic device is in working state or on standby state, the oil in the main oil tank 2 can be cleaned, and the operation is simpler.

[0022] The above describes the implementation mode of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned implementation mode. All other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.
