Description

Technical Field

[0001] This utility model relates to the field of forging press technology, and in particular to a circulating oil structure for a forging press. Background Art

[0002] Circulating oil is used when the forging press is working. Circulating oil is a lubricating and cooling fluid used in the hydraulic system of the forging press. Its main function is to maintain the stable operation of the hydraulic system, help transmit power, reduce friction, reduce wear, clean the inside of the system, and effectively remove the heat generated during operation through circulation.

[0003] Application No. 202220588345.3 specifically describes a circulating oil structure for a forging press, including a base and an oil tank. The oil tank is located on the upper surface of the base, and mounting grooves are symmetrically formed on both sides of the oil tank. A mounting frame is movably mounted inside the mounting groove, and several sets of semiconductor cooling chips are arranged inside the mounting frame. Fixed seats are symmetrically arranged on both sides of the mounting groove, and a fixed pressure rod is movably mounted on the surface of the mounting groove. A rubber pressure plate is provided on the lower surface of the fixed pressure rod, and the side of the rubber pressure plate away from the fixed pressure rod is in contact with the surface of the semiconductor cooling chips. In existing circulating oil structures for forging presses, the hydraulic oil is easily affected by the ambient temperature during use. In winter, the hydraulic oil temperature is low when the machine is first started, resulting in poor hydraulic oil flow. In summer, the hydraulic oil temperature is high after working for a period of time. Both high and low temperatures are detrimental to the stable operation of the forging press.

[0004] The above solution has shortcomings in use. Due to the action of the agitator, the hydraulic oil is continuously stirred in the oil tank, which keeps the hydraulic oil in a constant state of flow. Although the semiconductor cooling chip can reduce the temperature of some hydraulic oil, this cooled hydraulic oil will always be trapped inside the oil tank. At the same time, the hydraulic oil that has not been sufficiently cooled will gradually transfer heat to the cooled hydraulic oil under the action of the agitator, causing the temperature of the cooled oil to rise, thus affecting the heat dissipation efficiency of the hydraulic oil. To address this, we provide a circulating oil structure for forging presses. Utility Model Content

[0016] Beneficial effects:

[0017] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] First Embodiment

[0027] As attached Figure 1 Appendix Figure 2 To the attached Figure 3 As shown: A circulating oil structure for a forging press includes an oil storage tank 1, an oil inlet pipe 2 and an oil outlet pipe 3 located on the top of the oil storage tank 1, and a water tank 4 located above the oil storage tank 1. By utilizing the cooperation of the oil inlet pipe 2 and the oil outlet pipe 3, the hydraulic oil can achieve the effect of recycling.

[0028] A set of equally spaced heat-conducting plates 7 are embedded on both the left and right sides of the oil reservoir 1. The heat-conducting plates 7 can be used to dissipate heat from the hydraulic oil inside the oil reservoir 1.

[0029] The heat absorption component 5 is disposed outside the oil inlet pipe 2 and the oil outlet pipe 3, and includes a sleeve 501 sleeved outside the oil inlet pipe 2 and the oil outlet pipe 3. Each sleeve 501 is connected to the top of the oil storage tank 1, which can prevent external heat from entering the sleeve 501 and affecting the heat dissipation effect.

[0030] The heat-absorbing structure, located above the oil storage tank 1, includes a pump body 502 mounted above the oil storage tank 1. The input end of the pump body 502 is connected to a water suction pipe 503, and the output end of the pump body 502 is connected to a first T-shaped pipe 504. Both output ends of the first T-shaped pipe 504 pass through a sleeve 501 and are connected to condenser pipes 505. The two condenser pipes 505 are respectively fitted outside the oil inlet pipe 2 and the oil outlet pipe 3. The output ends of the two condenser pipes 505 are connected to a second T-shaped pipe 506. The output end of the T-tube 506 is connected to the water tank 4. When the pump body 502 is working, the water suction pipe 503 will draw out the cooling water inside the water tank 4. The cooling water will enter the condenser pipe 505 through the first T-tube 504. When the hydraulic oil flows from the oil inlet pipe 2 and the oil outlet pipe 3, the water flowing inside the condenser pipe 505 will absorb the heat in the hydraulic oil, which can reduce the temperature of the hydraulic oil entering the oil storage tank 1. At the same time, it can also cool down the hydraulic oil drawn out of the oil storage tank 1 again, ensuring the heat dissipation effect of the hydraulic oil.

[0031] Two reinforcing blocks 507 are fixedly connected to the outer surface of each condenser tube 505. The other side of each reinforcing block 507 is connected to the inner wall of the sleeve 501. This can effectively fix and stabilize the condenser tube 505, ensuring that the condenser tube 505 will not be displaced due to vibration outside the oil inlet pipe 2 and outside the oil outlet pipe 3, thereby maintaining good contact and heat exchange performance of the condenser tube 505.

[0032] Second Embodiment

[0033] As attached Figure 1 To the attached Figure 4 As shown: Cooling component 6 is set at the bottom of oil tank 1 for dissipating heat from the water inside water tank 4. Cooling component 6 includes a partition 601 set at the bottom of the inner wall of water tank 4. A set of heat dissipation fins 602 arranged at equal intervals are embedded on the upper surface of partition 601. The heat dissipation fins 602 can conduct heat from the water inside water tank 4, thereby reducing the water temperature.

[0034] A set of blowers 603 is installed on both the front and back of the water tank 4, and protective covers are provided on both the front and back of the water tank 4. By using the blowers 603, air can be blown to the heat dissipation fins 602 to dissipate heat, which accelerates the heat dissipation of water and is conducive to water recycling.

[0035] Air vents 604 are provided on both the left and right sides of the water tank 4. Each air vent 604 is equipped with a filter screen. The air vents 604 can ensure the air circulation at the bottom of the water tank 4, and further ensure that the heat dissipation fins 602 can conduct heat from the water to the outside of the water tank 4.

[0036] The upper surface of the water tank 4 is provided with a sealing cover 605, and the outside of the sealing cover 605 is provided with anti-slip texture. The sealing cover 605 makes it convenient for staff to change the water in a timely manner, thereby ensuring continuous heat dissipation of the hydraulic oil.

[0037] Working principle: When in use, the pump body 502 is started, and the water suction pipe 503 draws out the cooling water from the water tank 4. The cooling water enters the condenser pipe 505 through the first T-shaped pipe 504. When the hydraulic oil flows from the oil inlet pipe 2 and the oil outlet pipe 3, the water flowing in the condenser pipe 505 absorbs the heat in the hydraulic oil, which can reduce the temperature of the hydraulic oil entering the oil storage tank 1. At the same time, it can also cool down the hydraulic oil that is drawn out of the oil storage tank 1 again, ensuring the heat dissipation effect of the hydraulic oil. After absorbing heat, the water will re-enter the water tank 4. The blower 603 is started, which blows air on the heat dissipation fins 602, which accelerates the heat dissipation effect of the heat dissipation fins 602 on the water, so that the water can continuously dissipate heat from the hydraulic oil.
