Abstract
Description
Technical Field
[0001] This utility model relates to the field of press equipment technology, and in particular to a press air cushion oil tank with a secondary oil tank buffer structure, used to stabilize the oil temperature in the buffer oil tank of the press air cushion tie rod. Background Technology
[0002] like Figure 1 As shown, this is a buffer structure of a press air cushion tie rod oil tank in the prior art. The tie rod 8 is connected to the top crown of the press air cushion and moves synchronously with the air cushion. The lower part of the tie rod 8 is connected to the main oil tank 1 for buffering.
[0003] In the oil tank buffer structure described above, the air cushion rod moves up and down with the air cushion during the operation of the press air cushion and is subjected to a large alternating force in both directions, which causes a large impact on the machine tool. In order to avoid the impact on the machine tool, a buffer oil tank is added to the lower end of the air cushion rod.
[0004] In the aforementioned fuel tank structure, when the air cushion rod repeatedly cushions the fuel tank, according to the principle of energy conservation, some kinetic energy will inevitably be converted into heat energy, causing the fuel tank temperature to rise. Excessive fuel tank temperature will shorten the lifespan of the fuel and seals, and significantly reduce the cushioning effect. Without reducing work efficiency, conventional heat dissipation methods include: 1. Increasing the fuel tank volume; 2. Adding cooling fins to the fuel tank cylinder; 3. Physical cooling. These methods are all based on the fundamental principles and theoretical calculations of air cooling, increasing the heat dissipation area A and the ventilation coefficient K to cool the fuel tank. However, the fuel tank is a closed working area, and the generated heat cannot be effectively cooled. Unrestricted increases in fuel tank volume will lead to increased costs.
[0005] In the above structure, when the air cushion lever moves, the oil level in the tank will rise / fall rapidly according to the lever's movement. According to actual observation, when the lever falls and the oil level rises, the lubricating oil level in the tank does not rise steadily, but sprays out of the tank from the vent, causing environmental pollution and posing a safety hazard. Utility Model Content
[0006] This invention addresses the need for stable oil temperature control in the buffer oil tank of a press air cushion tie rod in the prior art by providing a press air cushion oil tank with a secondary oil tank buffer structure. By setting a secondary oil tank connected to the main oil tank and its buffer and anti-splash oil structure, the fluctuation of oil temperature in the main oil tank is reduced.
[0007] The purpose of this utility model is achieved as follows: a press air cushion oil tank with a secondary oil tank and a buffer structure, comprising a main oil tank, a pull rod connected to the upper end of the main oil tank and connected to the press air cushion, the main oil tank being filled with lubricating oil, an adjusting screw slidingly fitted on the outer periphery of the pull rod, an adjusting nut threadedly connected to the outer periphery of the adjusting screw, a worm gear screw adjusting mechanism on the outer periphery of the adjusting nut, a worm gear box on the outer periphery of the worm gear screw adjusting mechanism, a pull rod seat on the top of the main oil tank, a through hole at the center of the pull rod seat for easy fitting with the adjusting screw and adjusting nut, the lower ends of the pull rod and the adjusting screw extending into the main oil tank, and a buffer structure connected to the lower ends, characterized in that a buffer interface is provided at a slightly upper side position of the main oil tank, the buffer interface being connected to an oil pipe, the other end of the oil pipe being connected to a secondary oil tank, the secondary oil tank being provided with an anti-splash oil structure and an oil level gauge, an exhaust buffer pipe on the top of the secondary oil tank, and an inspection port and an oil overflow detection port on the side wall of the secondary oil tank.
[0008] To ensure the main oil tank is filled with oil, the bottom of the auxiliary oil tank is installed at a height higher than the top of the main oil tank. The bottom of the auxiliary oil tank is equipped with an oil inlet, which connects to an oil pipe. The anti-splash structure includes an oil baffle cap coaxial with the oil inlet, which is supported and fixed by several support rods arranged around the outer periphery of the oil inlet. The oil baffle cap, located in the oil inlet direction, prevents oil splashing caused by oil inflow impact.
[0009] To effectively prevent oil from entering the oil port, the diameter of the cap top is larger than the inner diameter of the oil inlet, and the brim of the cap expands downwards and outwards.
[0010] To further prevent shock fluctuations when oil enters the auxiliary oil tank, an oil baffle plate is also provided inside the auxiliary oil tank on the upper side of the oil baffle cap, and the oil baffle plate has a through hole in the center.
[0011] To prevent oil mist from overflowing during exhaust from the auxiliary fuel tank, the exhaust buffer pipeline includes an upward-extending exhaust pipe, the other end of which is provided with a horizontal pipe section, and the end of the horizontal pipe section is connected to an air filter.
[0012] To ensure the lubrication of the worm gear adjusting mechanism, the auxiliary oil tank is also provided with a worm gear box lubrication oil pipe connected to the worm gear box on the side wall near the main oil tank.
[0013] The advantages of this utility model's press air cushion oil tank with auxiliary oil tank buffer structure are as follows: Based on the original air cushion tie rod buffer oil tank structure, an auxiliary oil tank is added, increasing the overall volume of the oil tank; as an oil tank in a separate, independent space, the auxiliary oil tank has significantly better ventilation and heat dissipation than the main oil tank, ensuring sufficient and timely cooling of the oil inside, thus ensuring stable oil temperature in the main oil tank; simultaneously, the anti-splash structure inside the auxiliary oil tank prevents oil splashing caused by oil inlet impact; a horizontal buffer pipe is installed in the exhaust pipe of the auxiliary oil tank to prevent oil mist carried by the exhaust from being discharged from the exhaust outlet, and an air filter is further installed at the end of the exhaust port to prevent foreign objects from entering the pipe, thus ensuring the cleanliness of the auxiliary oil tank's interior.

[0018] The following describes in detail, with reference to the accompanying drawings, the press air cushion oil tank with auxiliary oil tank buffer structure of this utility model.
[0019] like Figure 2 and Figure 3As shown, the press air cushion oil tank with auxiliary oil tank buffer structure of this utility model includes a main oil tank 1. The upper end of the main oil tank 1 is connected to a pull rod 8 connected to the press air cushion. The upper end of the pull rod 8 moves synchronously with the press air cushion to buffer the impact generated when the air cushion moves. Therefore, the following oil tank buffer structure is set at the lower end of the pull rod. Specifically, the main oil tank 1 is filled with lubricating oil. The pull rod 8 is slidably fitted with an adjusting screw 4. The adjusting screw 4 is threadedly connected to an adjusting nut 5. The adjusting nut 5 is equipped with a worm gear screw adjusting mechanism 6. The worm gear screw adjusting mechanism 6 is equipped with a worm gear box 7. When the press air cushion lifts and lowers, the pull rod 8 can slide axially along the central hole of the adjusting screw 4. The top of the main oil tank 1 is equipped with a pull rod seat 3. The center of the pull rod seat 3 is provided with a through hole for easy fitting with the adjusting screw 4 and the adjusting nut 5. The lower ends of the pull rod 8 and the adjusting screw 4 extend into the main oil tank 1, and the lower ends are connected to a buffer structure 2. The main oil tank 1 is provided with a buffer interface at a slightly upper side position. The buffer interface is connected to an oil pipe 9. The other end of the oil pipe 9 is connected to an auxiliary oil tank 14. The auxiliary oil tank 14 is equipped with an anti-splash oil structure 12 and an oil level gauge 17. The top of the auxiliary oil tank 14 is equipped with an exhaust buffer pipe 15. The side wall of the auxiliary oil tank 14 is equipped with an inspection port 13 and an oil overflow detection port 19.
[0020] To ensure that the main oil tank 1 is full of oil, the bottom of the auxiliary oil tank 14 is installed at a height higher than the top of the main oil tank 1. The bottom of the auxiliary oil tank 14 is provided with an oil inlet 11, which is connected to the oil pipe 9. To prevent the oil from splashing into the auxiliary oil tank, the anti-splash structure 12 of this utility model includes an oil baffle cap 1201 coaxial with the oil inlet 11. The oil baffle cap 1201 is supported and fixed by several support rods 1202 arranged around the outer periphery of the oil inlet 11. To achieve effective oil blocking, the top diameter of the oil baffle cap 1201 is larger than the inner diameter of the oil inlet 11, and the brim of the oil baffle cap 1201 is expanded downward and outward, which can guide the oil flow obliquely downward along the brim, effectively preventing the oil flow from splashing upward.
[0021] To further prevent oil ingress shock fluctuations in the auxiliary oil tank 14, an oil baffle plate 18 is also provided in the auxiliary oil tank 14 on the upper side of the oil baffle cap 1201. The center of the oil baffle plate 18 is provided with a through hole so that the liquid oil can pass through when the oil level is higher than the oil baffle plate 18.
[0022] To prevent oil mist from overflowing when the auxiliary oil tank 14 is vented, the exhaust buffer pipe 15 includes an upward-extending exhaust pipe, and the other end of the exhaust pipe is provided with a horizontal pipe section, the end of which is connected to an air filter 16.
[0023] To ensure the lubrication of the worm gear adjusting mechanism 6, the auxiliary oil tank 14 is also provided with a worm gear box lubrication oil pipe 10 connected to the worm gear box 7 on the side wall near the main oil tank 1. The lubrication of the worm gear adjusting mechanism 6 is achieved through this lubrication oil pipe.
[0024] This utility model discloses a press air cushion oil tank with an auxiliary oil tank buffer structure. Based on the original air cushion tie rod buffer oil tank structure, an auxiliary oil tank 14 is added to expand the overall volume of the oil tank. Since the auxiliary oil tank 14 is an oil tank in a separate independent space, its ventilation and heat dissipation effect is significantly better than that of the main oil tank 1, which can ensure that the oil in the tank is fully and timely cooled, thereby ensuring the stability of the oil temperature in the main oil tank 1. At the same time, the anti-splash oil structure 12 in the auxiliary oil tank 14 avoids oil splashing caused by oil inlet impact. The exhaust pipe of the auxiliary oil tank 14 is provided with a horizontal buffer pipe to prevent oil mist carried by the exhaust from being discharged from the exhaust outlet. Furthermore, an air filter is installed at the end of the exhaust port to prevent foreign objects from entering the pipe, thereby ensuring the cleanliness of the interior of the auxiliary oil tank.
