Description

Technical Field

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

[0002] Hydraulic devices are mainly used for press forming. Taking wheel hub processing as an example, the raw materials are placed on the lower die, and the upper die presses the raw materials downward to press the raw materials into the shape of the wheel hub according to the shapes of the upper and lower dies. The pressure of the hydraulic device comes from the oil cylinder, so an oil tank needs to be set up in the hydraulic device to supply oil to the oil cylinder. After long-term use, many impurities such as metal debris will be generated in the oil cylinder, so the oil in the oil cylinder needs to be released and filtered, and then the filtered oil needs to be re-injected into the oil tank, which is more troublesome. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a hydraulic device with an integrated auxiliary oil tank to solve the technical problem in the prior art that impurities in the oil filter of the hydraulic device tank need to be discharged from the tank, filtered and then injected back into the tank, which is a relatively cumbersome operation.

[0004] In order to solve the above technical problems, the present invention provides a hydraulic device with an integrated auxiliary oil tank, including a device body, a main oil tank and an auxiliary oil tank, the main oil tank and the auxiliary oil tank are both connected to the device body, an oil chamber is arranged in the auxiliary oil tank, the oil chamber includes an oil return area, a cooling area, an oil suction area and a sedimentation area, a partition arranged in a vertical direction is provided in the auxiliary oil tank, the partition separates the oil return area, the cooling area and the oil suction area on the left and right sides of the partition, a sedimentation area is formed between the lower end of the partition and the bottom end of the auxiliary oil tank, the sedimentation area is connected with the cooling area and the oil suction area, the cooling area is connected to the main oil tank, a cooling assembly is provided in the cooling area, the auxiliary oil tank is connected to a plurality of oil pumps for pumping oil in the oil suction area back to the main oil tank, the oil inlet of the oil pump is connected to the oil suction area, the width of the sedimentation area gradually decreases from top to bottom, a drain outlet is provided at the bottom of the sedimentation area, and the drain outlet is detachably connected to a drain plug.

[0005] After adopting the above structure, the hydraulic device with an integrated auxiliary oil tank of the present invention 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 to be 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 impurity density in the oil is greater than 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. It only needs to open the drain port regularly to discharge the impurities. Regardless of whether the hydraulic device is in working state or on standby state, the oil in the main oil tank can be cleaned, and the operation is simpler.

[0006] As an improvement, the upper end of the partition is connected to the top of the auxiliary oil tank; this structure prevents the oil in the main oil tank from flowing directly into the oil suction area, ensuring that the oil is fully cooled and precipitated.

[0007] As an improvement, the cooling assembly includes a plurality of cold water pipes vertically arranged in the cooling zone; this structure has the advantage of being simple in structure.

[0008] As an improvement, the auxiliary oil tank is provided with a water inlet and a water outlet connected to the cold water pipe; this structure facilitates timely replacement of the cooling water in the cold water pipe to ensure the cooling effect.

[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 by 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 inclined from top to bottom towards the other baffle. With this structure, the two inclined baffles guide the precipitated impurities, assisting 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, thereby facilitating the discharge of the sediment and improving 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] A hydraulic device with an integrated auxiliary oil tank according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1 to Figure 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, both of which are connected to the device body 1, wherein the main oil tank 2 is a prior art and will not be described here, and 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 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 zone 43 is formed between the lower end of the partition 5 and the bottom end of the auxiliary oil tank 3, and the sedimentation zone 43 is connected with the cooling zone 41 and the oil suction zone 42. That is to say, the cooling zone 41 can only be connected with the oil suction zone 42 through the sedimentation zone 43, and the cooling zone 41 is connected to the main oil tank 2. Specifically, an oil return zone 14 is formed on the upper part of the cooling zone 41, and the cooling zone 41 is connected to the main oil tank 2 via the oil return zone 14. A cooling assembly is provided in the cooling zone 41, and the cooling assembly includes a plurality of cold water pipes 9 arranged in the cooling zone 41 along the 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, and the connecting port of the cooling zone 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 a plurality of 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 port 7 is provided at the bottom of the sedimentation area 43. The drain port 7 is detachably connected to a drain plug 8. Specifically, the drain plug 8 is threadedly connected to the drain port 7.

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

[0021] Since the main oil tank 2 is connected with 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, and the impurities will settle at the bottom of the sedimentation area 43. 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 easier.

[0022] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned one embodiment, and all other embodiments obtained by those skilled in the art without making any creative work belong to the scope of protection of the present invention.
